A eulogy for Twitter - zabramow http://www.theatlantic.com/technology/archive/2014/04/a-eulogy-for-twitter/361339/?single_page=true ====== teaneedz I'm one of those exploring elsewhere. Twitter today feels even more dysfunctional as a company. The pursuit to become algo driven and Facebooky reached its limit for me with the new link previews which fundamentally transform the Twitter experience from being text based to visual. The problem though is that the entire timeline is now visual with a spammy marketing vibe because most people today use Twitter for sharing links, not specifically for photos. The resulting photos from link previews are not interesting for the most part and certainly don't convey the fun that a visual experience such as Ello conveys. Because Ello supports Markdown and text can live just fine there, I've personally made it my place to play and relax. I updated my Twitter bio to indicate that my tweets will become stale. I will still tweet now and then, minus my personality. Ello has been a relaxing experience for me, but I miss the in-the-now vibe of Twitter. I'll miss Twitter, but never really forget it.

Steve Jobs' old resume from his mac.com page - nikcub http://replay.waybackmachine.org/20090204025538/http://homepage.mac.com/steve/Resume.html ====== yoda_sl Folks it was just a marketing page just to show what you could publish with the web app HomePage which was part of the iTools suite. Don't take it seriously ! I know a few folks that used to work in iTools and .Mac and it was well known that Steve's web pages where just for demo purpose. ~~~ benatkin Got a reference? I think it could have been made by a fan. It doesn't have any information that isn't available publicly. With the same phone number appearing in four places, it doesn't seem particularly like Jobs. ~~~ yoda_sl When Apple released iTools / .Mac and so on, even recently with Ping they usually reserve a bunch of name for either marketing pages or of their own usage. Many exec have usually their accounts created way ahead before the services goes live, and often Apple product name are reserved or unavailable. When Apple did introduce iTools at MacWorld January 2000, a few days afterward every employee at Apple got a mac.com/iTools account based on their existing apple.com email address. ------ alexobenauer On the first Apple employment: "Learned many things, including do's and don'ts for building executive teams." Snide remark of the year? ~~~ edo Wish he wrote those do's and don'ts down. ~~~ nikcub not sure how it can apply to a startup, but it would be 'do not hire John Sculley to run your company' ~~~ jarin Unless your company is PepsiCo, that is. ------ jamesrom I don't know if this is supposed to be some tongue in cheek demo of Apple iTools, but I get the feeling after reading that résumé, that if Jobs had to start from nothing again, he could. ~~~ oscardelben Success is a habit. I bet that most successful individuals who started from scratch, if sent in a foreign country with no connections or resources at all, would recreate their level of success given enough time. ~~~ zrgiu I actually know someone from Somalia who got successful there, got screwed and left to Holland. Got successful there again, and again got screwed and left to Romania. He has a successful business here, and he probably won't get screwed again :P After the first "failure", his connections helped him rise again. ~~~ jergason Can you say that "getting screwed" is a habit too then? ------ alexobenauer More interestingly, this site first was noticed by Wayback on September 25, 2000. (Presumably about the time it was first published). Apple's homepage at that time: [http://replay.waybackmachine.org/20001008232304/http://apple...](http://replay.waybackmachine.org/20001008232304/http://apple.com/) ~~~ p0ppe It's fascinating how little the homepage has changed over the years. ------ Evgeny _"Discovered a little animation company that needed a vision."_ That's so amazing - or amusing - I absolutely can not tell if this is humbleness, irony, some bragging disguised as humbleness or something totally else ... ~~~ monopede Actually he bought Pixar to turn it into a hardware company. John Lasseter is probably the bigger reason why it became such a successful animation company. Of course, thanks to Steve the company survived long enough to discover its true purpose and thanks to Steve got such a great deal with Disney for marketing the initial movies. ~~~ jakarta Yeah, if you read "The Pixar Touch" you get a good picture of what Jobs hoped to achieve with Pixar (focusing on selling the hardware to consumers). His main contribution was money. I think it was only after Toy Story did he truly "get" how good the computer animated films could be. It's funny because in the book they describe the brief period where Pixar was owned by George Lucas, and he too did not have faith in computer animated films. ~~~ nikcub I remember reading something along the lines of 'Jobs saw Pixar as the next SGI' - which matches a lot of what has been said in Pixar biographies ------ allenbrunson This can't be real. What type of employer would say "Oh, Steve Jobs. Yes, I think I may have heard of you, but let's have a look at your resume before we get serious." And would Steve really write that one of his skills was "That 'vision thing?'" ~~~ alexobenauer I think he's being modest for the asset that most clearly has. Being a visionary is his greatest strength, I think he humbles it down by saying it like that. ~~~ allenbrunson I'm not contesting Steve's vision. This just seems too cutesy to be serious, by several orders of magnitude. If this was really Steve's home page, I bet he put this up as a joke. ~~~ rahoulb It used to be the marketing page for iTools (which became mac.com which became MobileMe). I used to think it was a nice (slightly tongue in cheek) way of promoting the service. ------ bluehat That's a remarkably informal tone of writing for a resume. Is Steve Jobs just casual or have resumes gotten more formal? ------ elvirs I have great experience, lots of energy, a bit of that "vision thing" Yeah, just a bit of vision thing :) ------ dustingetz its likely fake. homepage.mac.com was for public content, kinda like geocities. ------ reason This résumé looks far better than many I come across today, aesthetically. ------ rbanffy Wow! Rounded corners! ------ razin Curious as to why he wrote "Left in 1986 to decide which step to take NeXT" under his first stint at Apple. I thought he was fired by John Sculley. ~~~ willifred The Apple board reduced Steve Jobs's role at Apple to ceremonial/figurehead. Steve Jobs actually resigned from Apple. [http://folklore.org/StoryView.py?project=Macintosh&story...](http://folklore.org/StoryView.py?project=Macintosh&story=The_End_Of_An_Era.txt) ------ ammarkalim "references: available on request" I wonder who will Steve Jobs ask for references...woz? Bill gates?...oh yes i think it would be Mark Zuckerberg..haha ------ ammarkalim guys..seriously is thing real? i always thought it was made by some fan boy ------ alexobenauer What's interesting to me is I can't imagine why he would need this unless he was looking to move on to his next thing after apple. This isn't a list of accomplishments - it's a resume, geared to sell someone on why this guy should be hired.

YC Demo Day: Why I Pitched BARE Foot + Tips for Being Relaxed on Stage - jkresner http://hackerpreneurialism.com/post/81222695099/pitching-airpair-bare-foot-tips-for-relaxed-on-demo-day ====== swederik This looks incredibly useful for researchers, though you'll need to offer a lower price. e.g. I'm a neuroscientist. Say I have a question about whether or not to perform fiber tractography through brain regions that show hypointense lesions, like in multiple sclerosis. There are probably a few thousand people that could give decent answers to solve the problem, and less than a hundred that could directly answer it more-or-less definitively (since they are likely to be the eventual paper's reviewers). I'd certainly be willing to pay to get that answer up front. Especially when the alternative is doing your best and having to redo the analysis and rewrite the paper later. ------ aerosmile While pitching barefoot might not work for everyone, watching the referenced TED talk and the Tropical Thunder scene are highly recommended!

Show HN: Make Me Work – a solution to procrastination - sixhobbits https://make-me-work.com ====== sixhobbits Hey HN, creator here. I've been thinking about remote personal assistants for a while, but it's quite a bit to get off the ground. After publishing a book recently and realising how important the role of my editor was, mainly just in her role of checking that I was writing, and helping me set short-term deadlines, I decided on productivity assistants instead. I hope to grow the idea into a full-blown PA service (people who can organize phonecalls and other admin tasks for you), but for now these people will be around to talk to you and help keep you productive. Feedback on the idea, site, or anything else would be highly appreciated. Specifically: \- Do you see the need for a service like this? \- Do _you_ need a service like this? \- How much would you be willing to pay for a service like this? As mentioned in the pricing page, I'm giving a trial of the service free for the first 5 members (1 month each), so feel free to be one of those five if you're working on a project at the moment and battling to find motivation to put in the hours. ~~~ magic_beans The site's design is very lovely EXCEPT for the drawer menu. I spent a couple minutes looking for more information before I finally realized I ought to click the menu drawer. It was frustrating after committing the time to read through the front page. Design suggestion: put your 4 drawer items into the main nav so a user can immediately find more detail after reading the intro page. ~~~ novium Possibly a call-to-action-like button or something similar would be nice as well. Otherwise I certainly like the idea ~~~ brudgers I would say a call-to-action button is a necessary change if a high priority goal is to be a business. ~~~ sixhobbits Thanks for the feedback! As I'm running this solo and on the side for now, the priority for me is experimentation and to see if I can find even 5 people who would be keen on the idea. If it goes well I'll definitely completely change the pricing page and add a call-to-action on the main page. ~~~ geoelectric Just make sure you know what you're getting into. The type of coaching you describe is something people typically get training for. It goes past simple project management skills since you're dealing 1:1 with their personalities and other life considerations as well. Even if you don't bring those into the conversation they'll play hell with the results--that may mean it's unavoidable to bring them into the conversation as "blockers" or "risks" and that potentially opens a can of worms. One suggestion I'd throw out is to do the market research to figure out how many people have severe enough procrastination issues to benefit from your services, but who are otherwise sufficiently well-adjusted to not be more than you could handle. How many people out there really do just need another pair of eyes and a nudge, but are sufficiently isolated that they would have to turn to this kind of service to get them? Otherwise you might find yourself in a non-existent niche between people who just needed a todo program and people who actually need serious help. If you don't screen out that second type somehow, assuming you're not set up to handle them, they'll potentially confound your scaling calculations by being exceedingly high maintenance and they'll have a bad experience as well. ~~~ sixhobbits Very good point. I definitely don't want (in the extreme case) suicidal customers who expect me to fix their problems! The "market research" I've done has been extremely informal and involved me describing the idea to some academics (mainly master's/PhD candidates and a couple of freelancers). I've had mainly positive feedback on the idea -- from people who lean more towards your "just need a todo program" than "need serious help". I'll definitely put some thought into screening out the latter group, as neither I nor the PAs will be qualified to deal with them. ------ andrewfromx why use a dot com domain and dashes? There are so many new top level domain options now. What about dowork.club or procrast.stopper just anything other than .com and dashes in the domain! You might as well have a "the" in there too :) ~~~ sixhobbits A few other people (outside of hn) have complained about the dashes :) I'm considering alternatives! I do still think that .com is preferable, both because it's the first thing a lot of people try if they only remember the name and not the TLD, and because a lot of the new TLDs (especially .club and others that you can get on namecheap's 88c deal) are being used for pretty crummy businesses. Obviously if I can get to top of Google results for a couple of decent queries, neither problem matters too much. ~~~ andrewfromx i really like the people running [http://get.club](http://get.club) they are helping us at every step. Lot of professional sports people moving to dot club. ------ rmasis I think it is definitely a neat idea! I would use this-- but not right now.

Update on Taking Tesla Private - chollida1 https://www.tesla.com/blog/update-taking-tesla-private?redirect=no ====== hn_throwaway_99 > I left the July 31st meeting with no question that a deal with the Saudi > sovereign fund could be closed, and that it was just a matter of getting the > process moving. This is why I referred to “funding secured” in the August > 7th announcement. He has a waaaaaayyy different definition of "secured" than I (and I think the SEC) do. That tweet is going to cost Tesla and Musk big time. ~~~ garmaine I don't know, that sounds like a handshake agreement, right? I wouldn't balk at calling a handshake agreement "secured" given the context. ~~~ gamblor956 Between businesses, a handshake agreement means nothing. If the agreement is not committed to paper it doesn't exist. However, a handshake agreement could be valid between individuals depending on the context. ~~~ tpetry It‘s funny. In Germany a handshake agreement between individuals is worth nothing but between businesses it‘s enforcable like a written contract. ~~~ gamblor956 We're not in Germany. Contract laws vary by country and by state. In the US, the general law is that verbal contracts are worth the paper they are written on, which is to say, not at all unless other facts/circumstances support the existence of the verbal agreement _and its specific terms._ Otherwise anyone could claim to have a contract with anyone else. For example, I claim to have had a verbal agreement with Mark Z for the development of a social networking site owned by me but built by him. In the absence of any other facts, no court would agree that such a contract exists. However, maybe I show copies of emails where we discussed the idea for a social networking site before it launched. That's some evidence that a verbal agreement might have existed, but not as to what the terms were. Most likely, the parties would settle without going to trial, simply because Mark wants to proceed with the IPO without the sword of litigation hanging over his head-- even though he would very likely win. The marginal cost of winning at trial is not worth the much larger cost of the harm to the IPO. (This is very loosely based on the Winklevoss saga.) ~~~ checkyoursudo Your generalization is backwards. In general, US contracts do not need paper memorializing. The majority of transactions are not memorialized. Specific types of transaction and certain value thresholds require memorializing. Facts and circumstances are required to support verbal contracts, but _in general_ verbal contracts very much are enforceable. ~~~ gamblor956 Yes, of course. I'll ignore the law that I actually learned in law school and in the actual practice of litigating contracts for what some guy said on the internet... There's a reason I brought up the falling apple example. Verbal contracts are enforceable--if they satisfy the same requirements as written contracts. On top of that, the terms of a verbal agreement must be corroborated by other evidence outside of the verbal agreement itself in order to survive litigation --and the trend in the US legal system is to require _more_ supporting evidence. ------ Nokinside Private companies are allowed to have up to 2,000 shareholders under they fall under the same SEC reporting requirements as public companies. Tesla could keep big investors and smallish investors with over $1 million in investable assets or yearly income above $200k if they accredited themselves. Other issue is what kind of owner PIM is. In principle it's long term patient investor. KSA has a new active prince/ruler that is self assured and proud. He is really sovereign and relationship to him must be well managed. We all know that Musk not a diplomat in his public or private communications. Saudis have had little bit of cash flow problems because they have constant budget deficit is typically 10-15 percent of their GDP or ~$50B/year and it probably just grows in the future . On paper PIM has $2 trillion in assets, but most of it is Saudi Aramco. Aramco IPO would generate cash flow but it's delayed, probably because there is fair amount of air in the valuation. Saudi Arabia has previously inflated it's oil reserves as a political decision to match some OPEC agreements and real production capacity potential is top secret. If KSA continues to have cash flow problems and Tesla is disappoints somehow, Tesla may end up at the hands of corporate raiders like Carl Icahn. ------ csomar $358 is what TSLA is trading at right now (30minutes after this blog post hit HN). I'm guessing the traders are calling BS on whatever Musk has in hands. Imo, this looks like a stage to liquidate shorters (which Musk hates). Musk could have mentioned here that S.A. had "committed" in some way to a private deal. He didn't. They are still negotiating. There is literally 0 reasons why the stock will trade below $420 if the funding was "secured" let alone trade 15% below that. ~~~ freerobby There's more to a buyout than the funding though; lack of board approval or any agreement on terms (i.e. not just financial terms) are obviously deal- breakers. Certainly the market doubts whether this deal will go through, but it's not clear to me that it's all about Tesla's access to capital. ~~~ csomar I'd like to be convinced otherwise (both because I like what Tesla is doing and I think Musk is a great executer) but I don't find anything on that blog post that suggest that "funding is secured". ~~~ freerobby Oh, I agree about that. I'm just saying that even if everybody felt that funding was secured, the price would still not be at $420, because there are other risks of a deal like this falling through. ~~~ csomar Sure but this means that interested investors are willing to put $420 for Tesla. Which means its' price should be higher. ------ noir_lord That sounds like a retroactive arse covering exercise. ~~~ mikedouglas Specifically the section on "funding secured". Any reasonable person would interpret that as Musk having a term sheet in hand. This sounds more like "funding potentially interested". ~~~ dwighttk Especially since he later claimed: "Only reason why this is not certain is that it’s contingent on a shareholder vote." ------ abhiminator > Saudi Arabian sovereign wealth fund has approached me multiple times about > taking Tesla private. Interesting to see countries most dependent economically on fossil fuels heavily investing in their energy nemesis. Curious about the ramifications that might emanate out of partly giving away control of a large American automobile manufacturer to a foreign entity -- a potentially hostile one no less -- given how sensitive Tesla vehicles' proprietary technologies are from a safety/security standpoint. ~~~ dragonwriter > Interesting to see countries most dependent on fossil fuels heavily > investing in their energy nemesis. Saudi Arabia and Kuwait have been hedging against fossil fuels massively for many decades. It's been a driving force behind major regional conflicts with global participation, so it's kind of one of those things that people should generally be aware of. > Curious about the ramifications that might emanate out of partly giving away > control of a large American automobile manufacturer to a foreign entity You mean like when Chrysler got taken over by Fiat? ~~~ toyg To be fair, FIAT was hardly ever under the sort of nation-state influence that a sovereign fund is. They occasionally made business that "pleased", let's say, the Italian government, but it was decades before the Chrysler deal, and it was pretty rare anyway. Usually the relationship was the other way around, with the state making moves for the company to profit from, which is expected for any company. Sovereign funds are direct emanations of nation-states, which is different. When they buy a somewhat-strategic industrial asset, it is significant. The question is whether the US (and particularly this fossil-fuel-friendly administration) actually see Tesla as strategic at all - my guess is that the guys currently in charge wouldn't care one bit. ------ jaaames It's disconcerting this is written in the first person from Musk and not from a communications team as a public statement from the company. I think it's rather Freudian about his world view and behavior. He seems to have an opinion on everything and disregard experts left and right. I certainly wouldn't be comfortable with this personality running a company this size. Some CTO/engineering role, sure, CEO and board member with everything that entails is a time bomb. ~~~ mergejoin Have you considered the possibility that this blog article was reviewed by legal experts before being posted? I don't know of course but that's a possibility. ------ AlexandrB How is Tesla going private if the goal is for potentially _all_ its current shareholders to remain? Isn't there a limit on the number of investors a private company can have[1]? What if I own Tesla stock? Do I become a private shareholder afterwards? Does this just mean I don't get quarterly reports anymore? What if I still want to get quarterly reports? If I _am_ still getting the same reporting as before, in what meaningful way is Tesla private? None of this makes a lick of sense. [1] [https://blog.gust.com/limiting-the-number-of-shareholders- in...](https://blog.gust.com/limiting-the-number-of-shareholders-in-private- companies/) ~~~ JumpCrisscross > _if the goal is for potentially all its current shareholders to remain?_ Revise "all current shareholders" to "all current material shareholders" and Elon's tweets make more sense. > _Isn 't there a limit on the number of investors a private company can > have?_ Not technically. But you have to do all the expensive things a public company does if your "securities are 'held of record' by either 2,000 persons, or 500 persons who are not accredited investors" [1]. Practically speaking, those are the limits.

Would create special purpose fund enabling anyone to stay with Tesla. Already do this with Fidelity’s SpaceX investment." Still doesn't really make sense to me though. Not sure how that would work. ~~~ JumpCrisscross > _A tweet from [Musk]: "My hope..._ Elon expressed a hope, not a goal. Fidelity's SpaceX SPV is restricted to a small number of accredited investors. Goldman tried the "put investors in a box, put the box on the cap table, and call the box 1 investor" schtick when Facebook was private [1]. While Facebook went public before they fell afoul of the law, the authorities clearly expressed their views on such structures [2].

It's obvious that he loves it, but half the news about him is the stupid things he's done or said on Twitter or on blog posts. It does him no favors and makes him look like a child who has just figured out he can scream, and that the world will react when he does[0]. Elon, go back to what you're best at: inventing, being in the lab, running the factory, making the world better with your mind. Stop trying to be famous because it does you more harm than good. The biggest danger to Tesla today is an over-inflated ego. [0](I wonder if any politicians have figured this out?) ~~~ knight-of-lambd I disagree from a practical standpoint. Personal infamy is essentially free advertisement, up to a certain limit. As long as Elon isn't perceived as running the company into the ground. He spends a few seconds tweeting and suddenly his name and Tesla is plastered over the next news cycle. Great ROI. ------ uhnuhnuhn A Saudi government owned Tesla will lose me as a customer. If you're eager to do business with the Saudi government your moral compass is seriously out of whack. ~~~ berberous Greater good? For all the advantages and potential success of TSLA, it is in a precarious financial position and could fail. If the Saudis want to dump money into it and accelerate the world's transition to solar and electric cars, seems like a net win to me. ~~~ rsynnott If Tesla collapsed tomorrow, I don't see that that'd make a huge difference to adoption of electric cars in the long-term. Arguably, Nissan collapsing would be worse. The Leaf is a much better model for widespread adoption than Tesla's stuff. ~~~ MrEfficiency I was going to say GM's Bolt/Volt since it was one of those 'best cars of the year'. If that fails + is electric, thats a bad indicator for the future. Tesla gets a pat on the back for trying to be new/different. The quality of Tesla is nothing like established companies. You cant even blame Tesla, they dont have data like a company thats been around for decades. ~~~ rsynnott > I was going to say GM's Bolt/Volt since it was one of those 'best cars of > the year'. Barely available outside the US. There's the Opel Ampera, which is mostly a GM Volt, but it's weirdly expensive so no-one buys it. The Leaf is the world's best-selling electric car, for now (especially if you include its very close relatives like the Renault Zoe; I don't think that's precisely the same platform, but it's close). ~~~ greglindahl GM doesn't get California credits for selling Bolts outside of California and the other states that follow the California standard. Isn't the Leaf about to stop being the world's best-selling electric car? ~~~ rsynnott It's possibly been replaced by the BAIC EC, at least for the first part of this year. That's unlikely to last, though; the Chinese market is too fragmented for that. The BAIC EC is also of very limited relevance worldwide. ------ liaukovv To me it seems that the deal relies on 2/3 of current investors being willing to keep their money in the company while losing any leverage they have to control Elon at least in some way. I wonder if these estimations are correct, especially for bigger funds. ~~~ martin_bech Not at all true. if you have 20% of the stock of a private or public company is exactly the same voting wise etc. The only difference, is thats its publicly traded, and the pros and cons of that (very liquid, quarterly reports etc.). ------ haaen I'm wondering how Musk's compensation scheme will change when Tesla becomes private again. It was approved a few months ago by Tesla shareholders. It gives Elon Musk no salary, only restricted stock awards. They can reach a value of tens of billions of dollars. Restrictions for the full package: Tesla has to reach annual sales of 175 billion and the stock market has to give TSLA a market cap of 650 billion. ------ paulus_magnus2 __capital required for going private would be funded by equity rather than debt, __approximately two-thirds of shares owned by all current investors would roll over into a private Tesla. Musk needs to find 23 friends willing to put $1b into a retirement-fund. The fund takes over the existing shares and buys whoever wants to exit at $420. ------ JumpCrisscross > _the Managing Director of the [Saudi Arabian sovereign wealth] fund_ Does anyone know to whom this refers? ~~~ whatok [https://www.bloomberg.com/research/stocks/private/person.asp...](https://www.bloomberg.com/research/stocks/private/person.asp?personId=241125061&privcapId=12455701) that's what "PIF managing director" on google gives me. ------ panarky This is strategic for the Saudis. Other strategic investors and sovereign wealth funds that will not want to see Tesla controlled by a competitor for 10% over today's price. Norway, China and Abu Dhabi each have SWFs larger than Saudi Arabia [1], and the energy implications of letting Tesla go would be strategic for each of them. Tesla's market cap is only 6% of Apple's, and Apple isn't geopolitically strategic. We may see a bidding war for Tesla before they go private.

Elon Musk sent an e-mail to all his employees on August 7th, and published the e-mail to the world. In the e-mail he made a number of quite worrying statements as the CEO of the company and some outlandish claims. One week later on August 13th, Elon Musk rips off his mask and cackles manically: Behold! It was me all along! Not the mild mannered CEO of your heart, but I have been secretly talking as a potential bidder for your company! Moohahaha. ------ WhompingWindows I'd be interested to know who besides the Saudis are interested. Who are the biggest players? I'm guessing Elon has many, many wealthy friends with huge numbers of Tesla shares that are interested in this plan. ~~~ jbergens Maybe he could contact the Norwegian Oil Fund also. They should also be interested in something else than oil and Tesla sells a lot of cars there. [https://www.nbim.no/en/the-fund/](https://www.nbim.no/en/the-fund/) ~~~ agnsaft I cannot possibly imagine that Norway would gamble with such a large stake in a single company. Such funds usually have some strategies to reduce risk and thereby protect the wealth of their citizens. ------ _Codemonkeyism Sounds like trying to get the SEC away. ------ runamok I'm confused why elon says 2/3rds of shareholders would keep invested in a private Tesla. How would they ever get their money back out? Only if they went public in future or if they sold to another party? Based in their market cap compared to GM, Toyota, etc. that seems a bit crazy. ~~~ nickik You can still trade stocks and there are events to do that. ------ MrEfficiency Any idea why the Saudi (government) wants to buy Tesla? Is it part of the oil conspiracy to kill electric vehicles? Given how GM, Nissan, and others have electric vehicles, I dont think this could stop the new wave of buyers.

Show HN: Counters – GUI for those who don't do GUI - okaleniuk https://github.com/akalenuk/16counters ====== Evidlo Cool idea. Here's how to do it in Linux with files: # create the "counters" touch {01..16} # use multitail to show all counters in a grid, 4 columns multitail -s 4 * Now you can write to any of these files echo hello > 01 echo world > 16 The result looks like this: [https://i.imgur.com/yVWWMfr.png](https://i.imgur.com/yVWWMfr.png) You can also tell multitail to automatically rescan the directory and display new files # check current directory for new files once/sec. match any file multitail -s 4 -q 1 "*" ~~~ Phrodo_00 You can also have nice dialogs by using dialog/xdialog/zenity. For example, you can use named pipes and get a nice progress bar: mkfifo progress cat progress | zenity --progress --text='progress' --percentage=0 & echo 10 > progress sleep 10 echo '# Done!' > progress echo 100 > progress [https://help.gnome.org/users/zenity/3.32/progress.html.en](https://help.gnome.org/users/zenity/3.32/progress.html.en) [http://linuxcommand.org/lc3_adv_dialog.php](http://linuxcommand.org/lc3_adv_dialog.php) ~~~ brbsix I always use YAD, a much more feature-filled fork of zenity. [https://sourceforge.net/projects/yad- dialog/](https://sourceforge.net/projects/yad-dialog/) ------ saagarjha > The buttons seem misaligned but there is logic in it. The buttons that has > to do with the coutners are closer to the counters. And the buttons that > expose the window handler are closer to the window handler. And yes, the > number on top is the window handler. I'm having a bit of trouble understanding this, since I can't see how this works. How does [C], which "copies a C-style SendMessage template to the clipboard", have anything to do with exposing the window handler? ~~~ tastroder If you look at the SendMessage code examples, they contain the window handle as the first parameter. Looks like that's a convenience feature to reduce the amount of typing required to get data into the target. It basically generates code to communicate with the instance you pressed the button on I believe. ------ weinzierl I've heard from game dev circles that some use _Dear ImGui_ in the same spirit - as quick ad-hoc sort of GUI. A printf on steroids, if you will. ~~~ akx That + this post gives me an interesting idea... a local network interface for ImGui for environments where you don't have a native window, or there are no convenient bindings for ImGui. ~~~ tom_ See also imdebug: [http://www.billbaxter.com/projects/imdebug/](http://www.billbaxter.com/projects/imdebug/) ~~~ codetrotter From the name and context I was expecting something directly releated to ImGui, but imdebug is not directly related to ImGui nor to immediate mode GUIs in general in any way. Still interesting however, even though it wasn't what I was expecting. ~~~ tom_ It was the network interface aspect that made me think of it. ------ tastroder I wouldn't personally use this since my preference usually goes towards terminal UIs but I love seeing these personal productivity tools that people come up with. Nice work (and kudos on actually maintaining readable assembly code)! Isn't it annoying to have to change out window handles manually all the time? Or did that just become muscle memory after using the concept for that long? ~~~ okaleniuk I try not to keep the SendMessages for too long. We actually have a Linux gate-build at work so they only live on local machines. But every once in a while I spawn them all across the code to hunt some bug, and then I think I got it, and I do the victorious "Aha!" and close the window. And, of course, it's not it and then yes it gets annoying to update the handlers. ~~~ mst A thought sprung to mind: In *n?x environments, if I were implementing something like this I think I'd do it using an env var for sync. Think something like: $ eval $(start_counters); # start process, print 'COUNTERS_ID=...' $ ./myapp i.e. "stealing the way ssh-agent works for fun and profit" I'm suspecting you already thought of this sort of trick and rejected it as not worth the extra complication for the rare annoyance, but since it didn't pop into my head until hours after originally reading this comment I figure it was worth noting just in case. ------ pjc50 The ""deluxe"" (ie far more complicated) version of this might be to use ETW, which is one of those extremely Microsoft APIs that's both powerful but obtuse and can only really be learned from the one blogger providing examples. Which in this case is the amazing series of posts from [https://randomascii.wordpress.com/2015/09/24/etw- central/](https://randomascii.wordpress.com/2015/09/24/etw-central/) ETW would also work in those rare situations where SendMessage() doesn't, such as from a device driver, and can more easily be logged. ------ hanniabu From the title I thought it would be some type of data dashboard with a simple conf file to grab all the data. The conf file could have options like "endpoint" for the API endpoint, "type" for the chart type (bar, plot, pie, etc), "target" for how to target the data in the response (res["someData"]), or "targetx" and "targety" for graphs, "labels" and "axis" for assigning labels to the data, and "style" for selecting different variations for the graphs/chart such as solid/dotted/dashed for line types. ------ rs23296008n1 This reminds me of those old carpenter tools and worn workbenches. Deceptively simple and specific but its really a complex multitool full of subtleties embedded mostly in _how you use it_ rather than in another GUI or command line option. In assembly language _and_ targeting windows as well. Novelty++. ------ stiray Ehm, this just how windows work, you are having a hwnd (window handle) and message with optional parameters. There are hundreds of messages and WM_USER just defines start of custom defined messages. Typically you define your custome message as WM_USER + arbitrary number. And you also have PostMessage. ~~~ okaleniuk You're right, it is generally a good idea to use messages for this. It is also better performance wise to keep all the dispatching in one place. But I tried that at the very beginning and it was rather inconvenient since I had to drag defines to every place I want to send a message from. "WM_USER + 'R'" might have worked but it's worse than "WM_USER, 'R'" aesthetically. And there is an extra parameter anyway. PostMessage is also better for writing things to the counters since it's asynchronous. But it doesn't work for reading. It's just more convenient to have one function do both but of course you can post messages too. It's a silly tool anyway. Basically made of compromises. ------ vorpalhex Given that this is <500 lines of assembly this is frankly amazing given the overall complexity of the layout. Very clever. ------ 29athrowaway gnuplot, graphviz, ministat can help you visualize stuff fast. For interactive stuff, you can create a HTTP server and send requests to it from a web UI. For example, using this: [https://github.com/yhirose/cpp- httplib](https://github.com/yhirose/cpp-httplib) ~~~ weinzierl gnuplot and graphviz both are a staple but I've never heard of ministat so far - looks really useful though. ------ janci This is neat. From time to time I use a thing I call livedisplay. It is a http endpoint that you can send json message to an it will forward it to web interface via websocket. Obviously much more overhead than 16 Counters, but works on network and cross platform. ------ fareesh I can't relate to this environment or workflow but off the top of my head if I wanted to do something like this I'd use some kind of pub-sub and publish to it from one place and read from another - is that what this is ? Or am I missing something? ~~~ 0xffff2 Yes, except there isn't really a subscribe step so it's really just "pub". You are manually publishing messages to a static window handle. ~~~ fareesh Got it Is it not possible to just use redis or some windows equivalent for this kind of requirement? ------ bmn__ Oleksandr, I can't help but be reminded of [http://okcancel.com/strips/okcancel20031010.gif](http://okcancel.com/strips/okcancel20031010.gif) :) To be fair, your software probably was not intended to be used by anyone else and publishing it to Github is just for sharing the underlying idea. ------ momofarm MFC, still alive? In this “web” world, who still code use MFC framework? ~~~ FpUser Yours truly and many, many others. I do not actually use MFC as I only use C++ for servers. GUI things in my case go to Delphi/Lazarus. There is a whole world outside of that web juggernaut. ~~~ momofarm Delphi! Whaaaaat a surprise ! I still miss MFC/windows programming a lot, I think in many ways it's quite efficient. But for job seeking it's not a good idea, opening for windows gui is quite rare. Maybe I should setup a web(!!) For lonely job seeker on windows programming / and Delphi/lisp/scheme / all other good oldies forgotten by rest of the world. ~~~ FpUser Delphi is quite popular still in Europe.

How Good Are UW Students in Math? - slackerIII http://cliffmass.blogspot.com/2010/01/how-good-are-uw-students-in-math.html ====== lunchbox As shown on the scanned answer key, this was an anonymous quiz. College students have a tendency to put in pathetically minimal effort on things they're not being directly graded on. Also, the quiz's stated purpose was to help the teacher calibrate the assignments; maybe some students purposely answered questions wrong in hopes of dumbing down the class. (Though I don't dispute the author's central point.) ------ swolchok The author says that UW students taking Atmospheric Sciences s101 "should be the creme of the crop of our high school graduates with high GPAs". 1) Atmospheric Sciences 101 sounds like a "blowoff" class that liberal arts students would take only to fulfill a science requirement. In other words, the students are likely self-selected for lack of math/science ability. 2) UW is a public university. It may very well be the best public university in Washington, but I'd bet the best students have a nontrivial rate of private school attendance. (So as to dispel any illusions of elitism, I attended the University of Michigan, which is also a public research university.) ~~~ timr _"UW is a public university. It may very well be the best public university in Washington, but I'd bet the best students have a nontrivial rate of private school attendance."_ Don't kid yourself. This is an epidemic problem at _all_ schools, public and private. I have friends who teach at both public and private universities, and they all have the same horror stories. My own personal experience (private undergrad / PhD at UW) bears out their anecdotes. With certain institutional exceptions, private school kids are richer, not smarter. Also, the GPA and SAT scores of incoming UW freshman are _astonishingly_ high right now (IQR of 3.60-3.91 GPA, 570-680 SAT math, according to <http://admit.washington.edu/Numbers>). Admittedly, those aren't Harvard numbers, but one would still expect a 600 math SAT student to be able to do well on a basic high-school algebra quiz. ~~~ swolchok I did not disagree with the author's main point, merely the assertion I singled out. ~~~ timr Perhaps, but your argument was a challenge to the statement that the students represent the best and brightest of the state, and that's what I was addressing. When the test is as easy as this one, the argument that these students aren't elite isn't important. ------ chancho I'm just as upset with the state of math education in the US as anybody, but if UW is anything like my alma mater, then "Atmospheric Science 101" is a class that liberal arts majors take to satisfy their math & science general education requirements. A lot of these students (my wife, for example) have serious math anxiety. She could probably get a 70% on this test, even today, so many years after school, but throw it at her without warning on the first day of a non-math class and she'd literally cry. Now there's a case to be made that a good high school math curriculum should not leave anyone anxious about math, but I still think it's a bit of a leap to take this test and extrapolate to all students. ~~~ dschobel Same experience with my girlfriend. She has a good analytical mind (she graduated near the top of her law class) but she's just terrified of math. The weirdest aspects of this phenomenon are that: a) there's a very real fear of math unlike any other subject and b) there's no stigma against being mathematically illiterate as there is for other subjects (most likely because so many people just accept that "math is hard" and not for them). ~~~ spamizbad Is it any surprise, though? Math is taught in a manner that focuses very much on the _how_ but rarely ever the _why_. And while Discovery Math/Reform Math/etc are lambasted for not teaching kids to memorize certain algorithms, they do something else that's very important: encourage students to use creative problem solving skills to develop their own solution algorithms. I'm not going to advocate reform math in its current form, but I have to question traditional "drill and kill" teaching methods in today's modern world. If I can't remember how to find the area of a triangle, I just Google it. Drilling it into my brain would have made sense in the 1920's when there was no internet, no assurances my peers had the appropriate level of education to know such a thing, and possibly no ability to reach an "expert" via telephone to tell me the algorithm. I'd be completely reliant on my memory and (possibly) a math book if I was fortunate enough to have one with me. For all practical purposes, memorizing one half times base time height would have been the way to go in a pre-Internet era. Today, it seems like it's far more worthwhile to develop students who are solid problem solvers with strong information retrieval skills, as opposed to wasting precious time memorizing trivial algorithms that are readily available. ~~~ maximilian _Is it any surprise, though? Math is taught in a manner that focuses very much on the how but rarely ever the why. And while Discovery Math/Reform Math/etc are lambasted for not teaching kids to memorize certain algorithms, they do something else that's very important: encourage students to use creative problem solving skills to develop their own solution algorithms._ The idea sounds really great, but everything i've ever seen is that the students just end up terrible at everything. I even tried to teach it some, and the material seemed great to me as a teacher, but the students just never got it. I feel like the discovery idea makes a lot more sense in hindsight, but when learning that way, doesn't work out like hoped. However, I study applied math and I would say i learn in a more discovery way... But thats at the graduate level. ~~~ spamizbad If students are ending up terrible at everything, then the problem is deeper than just tradition vs reform. What's likely occurring is we are much better at teaching plug-and-chug than we are at developing problem solving. That's to be expected, as it's significantly harder to develop problem solving skills than it is to simply memorize steps, grade, correct, and repeat until perfect. This is especially true when you consider most math teachers really aren't trained in the art of problem solving, and were likely taught in a traditional manner themselves. As such they have no real frame of reference to go off of when attempting to foster problem solving skills in their students. ------ gommm And I remember in France how my university professors used to complain that high school students became weak in set theory... I didn't know that the level in the US had fallen that far... but it's true that I remember helping a girl in the nearby community college on her math classes and the level of the exercises she had was about the french 7-8th grade math. But of course, I think the emphasis on math in europeans countries is maybe different than in the us. In France, for example, ability in math is the main selection criteria and students who took the scientific curriculum in highschool had 6-8 hours/week of mathematics and for calculating the gpa, mathematics had a coefficient of 7-9 (compared to 3 for english for example). And because the scientific curriculum is considered the most prestigious a lot of students who intend to later study non-scientific specialities like law or business take it. ------ Dilpil Interesting premise, questionable conclusion. Kids can't do simple concept problems, so they need more drilling? Failure to calculate 1/.1 is not due to lack of practice, it is due to fundamental lack of understanding of fraction division. This is not a problem you fix via repeated long division of 4 digit numbers. This is a problem stemming from the fact that these students were never given a good idea of what the symbols they are being forced to move around really mean. And who cares that they don't know the definition of cosine, or the formula for the area of a circle? These are not fundamental ideas for non engineers. ~~~ mquander In my opinion, those are fundamental ideas for human beings in the year 2010; obviously we have to lower our expectations to match reality, but we shouldn't pretend they are unreasonable. Really, how difficult is the idea of a cosine? That's not exactly an unapproachable level of abstraction. Remember, these are people who have had _12 years_ of full-time mandatory schooling, and have signed up for a few more years on top of that. If anyone with an average IQ cared even a tiny bit about such things, they could learn all of it in half that time; and if they don't care at all, parents and teachers didn't do their job. Of course, I agree with the main thrust of your post. Somehow, you have to actually encourage (and allow) the students to understand what they're dealing with, instead of giving up, moving numbers and letters on paper, and passing to the next class. If that doesn't happen, there's no surprise that they've forgotten it six weeks after the course. ~~~ roundsquare I agree that just drilling on the mechanics of long division doesn't help. But, drilling the concepts can help. The point of the article is that instead of letting kids discover everything on their own and then feeling happy, teachers should direct their learning. In doing so, I would say they should drill the same concept repeatedly and ask questions that test both the ability to do the procedure and understand the concept. Anecdotally, this is how I taught my sister multiplication and how my friend tutored someone in calculus. ------ shalmanese In UW's defense, "Weather 101" is pretty commonly known as an easy class to fill up General Education requirements. ------ lutorm Another lament of what's wrong with mathematics, by mathematician Paul Lockhart: <http://www.maa.org/devlin/devlin_03_08.html> He doesn't quite agree with this article. ------ tigerthink Actually, I'm pretty sure this problem is exclusive to Washington. Go here <http://www.wheresthemath.com/> and scroll down to 'Washington State Facts'. Anecdote: I attend a community college in California, found the problems laughably easy, and have met tons of people in my classes who would feel much the same way. ------ tkahn6 I would bet these students got excellent grades in math. EDIT: As in, I'm sure that during high school they got high marks in math class without actually understanding the fundamentals of what they were 'learning'.

When CONSTants vary (critique of 'const' in C++) - samstokes http://james-iry.blogspot.com/2010/07/when-constants-vary.html ====== samstokes I've argued in the past for 'const' being a feature of C++ that would add value to other languages, but this article shows it's a more subtle and confusing abstraction than it appears. I'm not convinced the abstraction actually leaks - both the author's complaints are examples of "things you thought const guarantees when it doesn't" rather than "ways to circumvent what const guarantees" - but it doesn't mean what you'd instinctively hope it means. (I feel this oblique Princess Bride reference is justified given that, if you say 'const' in any part of your program, you really do have to keep using that word.) With all the talk of "support for immutable datatypes" I hoped Scala would do more to support this sort of programming - e.g. statically guarantee a function didn't mutate its arguments - but it actually offers less than C++ did. Forcing you to make the val/var choice for each variable is a nice improvement over Java's "mutable unless you go out of your way", and having performant immutable collections solves a common case (final reference to a mutable HashMap); but you're still basically relying on code inspection or documentation to tell you whether a given class is immutable. Having the type system able to tell you that would help both the authors of a class and its consumers. ~~~ gtani Mutations inplace are often done /necessary to make things performant with the JVM, viz clojure transients. For those playing along at home, the tapir book ("Purity Inside vs. Outside) and staircase book ("What makes an object stateful? p 357) are good little summaries. [http://programming- scala.labs.oreilly.com/ch08.html#PurityIn...](http://programming- scala.labs.oreilly.com/ch08.html#PurityInsideVsOutside) ~~~ samstokes I'm not claiming that all data should be immutable, or even that all data in Scala should be immutable; just that when you _are_ using immutable data, the compiler should help you do that.

Ask HN: How to learn through freelancing? - vermasque I want to become a full-time Ruby on Rails developer. I've read things like this (http://www.quora.com/Ruby-on-Rails/What-are-the-minimum-level-of-skills-for-an-entry-level-RoR-job#) that range from as little as throwing a few sample apps on GitHub to joining a programmer school. However, it may be hard to be motivated to build a few sample apps that have no users, and I don't want to move far away to attend one of these schools. Another option I've thought about is freelancing on sites like oDesk or elance to learn through experience. I'll have real problems to solve, and I can do it from my current location. I could do freelancing for 6-9 months to prepare a portfolio to get the full-time gig. The freelancing only is needed to provide significant experience; I'm not expecting much money out of this. I've got the savings to cover the living expenses. If you've attempted to learn via freelancing, did it work? What were the pitfalls? I can see one issue being that a lot of these online freelancing websites have a lot of people applying for the jobs so it may be hard to get them as a beginner even with some sample apps ====== timmm Build your own projects and do freelancing on the side. Doing this will make you a better programmer, allow you to compile a portfolio, and earn you some cash.

Ask HN: Stuff for dads and sons to build together? - marcamillion I have a 2.5 year old son, and one of my dreams has been to build things with him. Preferably things that he would like to be able to use after we build it.<p>Any suggestions?<p>A variety of complexity, cost and time commitment would be appreciated.<p>Every day, around-the-house material, would be best. However, I am not opposed to having to buy a few stuff.<p>Thanks. ====== SwellJoe Stuff my dad and I made: Downhill racer painted to look like the General Lee. The go cart idea famousactress suggested is great, but costly. A downhill racer costs maybe 50 bucks, or a trip to the dump or polling your friends and family for parts (old lawn mower or bikes for wheels, for example). Tree house in the woods behind our house. A boat. Sort of. It wouldn't float, because my friend Steven and I put thousands of nails in it...Some sort of decoration or something. Wooden deck (this was for my mom, but it was a useful learning experience, and kids don't mind doing work, if it's kept light-hearted and easy going and they get to hang out with their dad while he's being awesome) Numerous electronics projects using various kits from Radio Shack. Eventually ended up with a 200-in-1 kit, that I saw on reddit a few weeks ago is still in production. The radio transmitters were always the most exciting for me, though extremely complex, especially if you want to be able to hear it all over the neighborhood (you need an amp and an antenna to really break federal law properly). Numerous computer projects. Mostly repairing old ones that we'd bought at garage sales and then reselling them. Numerous car projects, including fixing and doing oil changes and such on my own car when I got old enough to have one. All of these things led to me having a pretty severe DIY attitude...maybe too much so. I try to fix and build just about everything myself. This week, for example, I specced out what it would cost to take a box truck and turn it into the perfect motorhome ($29000, including a late model 17' medium duty diesel box truck with attic, and mostly new interior parts; about $9k less if most of the RV parts can be obtained through salvage sources, in case anyone is wondering). ------ famousactress Go Cart!!! Sorry. Lost opportunity from my childhood. Still pretty enthusiastic about turning a lawn mower into a race car, apparently. ~~~ SwellJoe You could make it an electric project these days, and teach environmental friendliness from an early age. All of the big problems with electric cars (range, battery weight/cost, lack of charging stations, charging time, etc.) aren't present in a go-cart, so solving the technical problems is much easier.

Why the US can beat China: The Facts about SpaceX Costs - cwan http://www.spacex.com/updates.php ====== mixmax Although it's a bit of an apple to oranges comparison Copenhagen suborbitals are on the trajectory to launching a human into space in around three years time. In a months time they'll have their first testflight from Bornholm in the baltic sea. They're doing this whole thing based on nothing but sponsors and goodwill. Their budget is around $8000 a month - orders of magnitude lower than spacex. They also built the worlds largest homemade submarine btw. Until now they've developed solid rocket boosters, parachutes, recovery programs, astrouanut survival and cockpit, etc. etc. and have not run into major problems yet. Some links: Website: <http://www.copenhagensuborbitals.com> Static test of solid rocket booster (110.000 HP): [http://www.youtube.com/watch?v=3g_xjGOJRws&feature=relat...](http://www.youtube.com/watch?v=3g_xjGOJRws&feature=related) TEDx talk by Christian Von Bengtson: <http://www.youtube.com/watch?v=ua9oGxNNGd0> All their technology is open source by the way. _Shameless plug:_ These guys survive on donations, and a few months ago I helped start a support organization to help them survive economicvally. It's $20 a month to be a member, and we really need more members so we can get these guys into space. If you feel this is a worthy cause and want to join send me an e-mail (it's in my profile). Our website is <http://raketvenner.dk/> (currently only in Danish...) ~~~ pdelgallego Are you guys developing any kind of software? I am a web developer, so I don't know much about C, but I am sure a lot of people here can help if you put a repository. ~~~ sukuriant Just a head's up. If there are human lives involved and at risk based on software development, it is incredibly, incredibly important that the software go through the highest possible level of testing, including every possible codepath, every input partition, everything. If it crashes midflight due to a bug, there's about nothing you can do about it. And people will die. Remember that when you're considering developing mission critical software. It is the most dangerous sort of software to write, and needs aggressively comprehensive testing. ~~~ count I mean this in the most positive fashion possbile, so please don't take it as just snarky assholism: It's that kind of thinking that would have prevented most of human achievement in the last few hundred years. If the people signing up to ride this open source rocket into space are aware of the risks, then let them take them. That doesn't mean don't put any care and testing into things, but don't turn into NASA when trying to innovate. ~~~ potatolicious There's a difference between a risk-taking pioneering spirit, and needless stupidity. There's also a difference between accepting the inherent dangers of primitive spaceflight, and being cavalier with people's lives. ------ Symmetry An illuminating anecdote: A while ago my friend from work was at an base where SpaceX would be launching from. However, during the launch an anomaly was discovered and the countdown was suspended. At this point all the Air Force people went home, since they were used to this sort of thing taking a week to sort out, but the SpaceX people quickly isolated the problem and the launch only ended up being delayed an hour. ------ protomyth I'm glad that SpaceX is so concerned with cost. It is sometimes hard for a company to stay focused on that when they get a government contract. As for the rest, I would imagine when robots get good enough, then the incentive to use cheap labor in China drops and factories in the US become more economically viable. ~~~ pradocchia I have often wondered whether free trade of goods has retarded the development of more sophisticated automation & robotics. What technology advancements have we missed out on when it's been cheaper to move manufacturing to China, rather than make capital investments at home? Note that any decision to off-shore is distorted by a) limits to the free movement of labor and b) currency manipulation. So at the margin, you might replace an efficient domestic operation w/ an inefficient foreign process, and make up the difference in currency and labor cost arbitrage. In such cases, free trade of goods alone has a detrimental effect on technological progress. Or at least that's the speculation. ~~~ Dove I don't mind. Sending manufacturing jobs overseas raises the standard of living there and introduces technology and industry to the region. The folks doing those jobs won't be stuck at that income level forever. I think my standard of living is pretty good. If I could have super robots next decade, or I could have them in three decades after conditions around the globe have equalized a bit . . . well, I don't mind the wait. ~~~ pradocchia True, it's probably better to forgo a degree of technological progress in some areas while the rest of the world catches up. And as it does, technological progress will still occur, just in different areas, like energy, transportation and computers. Health too, maybe. Actually, I have no idea what industries will respond to growing prosperity w/ higher capital investment in technology--at the moment it seems to be computers, but I don't know how far to project that into the future. I know some people project it off to a singularity. Time will tell! ~~~ JoeAltmaier I imagine the responders here are not blue-collar. So its easy to say "I don't mind that guy's job going overseas, it appeals to my liberal philosophy". While they lose their house, we feel warm inside. ~~~ Dove Yeah, nobody _ever_ outsources technical work. ;) I don't think anyone is ever entitled to work, whatever the industry. Especially if someone else wants to do the same work for cheaper -- be it with a machine or in another country. If you tell me someone lost their job and is having a hard time supporting their family, I do feel compassion. But the tool I reach for is charity, not a free job. It's not like there's a shortage of opportunity. If your skillset doesn't support your desired income -- especially if you find yourself unemployed -- go get some new skills. Whether it's reading a book about PHP or learning to repair refrigerators at the local community college, someone can pivot in a few months' time. (I wish this were more of an expected fallback; it seems like simple common sense to me.) In the mean time, the rest of us have cheaper products, and are that much richer. ~~~ JoeAltmaier It might be possible to reach that goal without rapid destabilizing change. Some folks don't retrain as easy as us, and have a real hard time when we change society as fast and often as we do. ~~~ Dove You know, I would normally let this sort of argument go, but you've stepped on a pet peeve of mine and it's been a while since it got some fresh air. I dislike arguments that focus on a particular consequence producing a particular strain of human misery, and dare the reader to disagree at the risk of being cold-hearted. I find the argument inappropriately personal -- focusing as it does on the virtue and piety of the person. But mainly I find it . . . well, myopic. Near-sighted. Take the outsourcing we're discussing. The suffering of the fellow who loses his job and maybe his house and has to move back in with his parents is one piece of the equation. The other piece is his counterpart in China who lives in worse conditions, and wants to work hard to improve life for him and his family, but lacks the opportunity. And then there's the cheaper product itself. There's the company that makes more money, which affects its shareholders and stock prices, which in aggregate affects people's retirement accounts. Perhaps one of _them_ is in danger of losing a house? And then there are the customers, who can now afford the cheaper product, or who can afford more other things because it _is_ cheaper. Perhaps one of _them_ is in a tight situation, too? And that doesn't even include tertiary effects. Perhaps this cheaper product is used as a component for something else new. Perhaps a whole new technology becomes feasible now. Perhaps it changes the _world_. Where does _that_ fit in the equation? That's why the argument strikes me as myopic. Our notional blue collar worker may indeed _be_ miserable, but who is to say his misery outweighs everyone else's? Why is he special? In fact, I find the reasoning to be kind of . . . maybe not exactly racist, but kind of people-ist in some way or another. I'm sorry for the guy, but I don't feel his concerns ought to trump anyone else's. I'm not saying you shouldn't try to figure out the impact of decisions on people at large. But I am definitely saying to have respect for how incalculable it can be, and to at least think in terms of all the people you can see right off will be affected -- and not just one class of them. I'm also saying to use the right tool for the job. As a rule of thumb, I like industry to make _progress_ , and charity to _relieve suffering_. Not that there aren't exceptions -- I myself am advocating the establishment of industry in a region as a way to improve conditions, and I certainly see the value of non-profit research. But usually I don't want the wires crossed. If you're worried about the suffering of folks who have lost jobs and are having trouble making ends meet, the right approach seems to me to start or assist a foundation that helps those sorts of folks financially and educationally (or whatever). Limiting the help to, say, textile manufacturing workers, and having the help come in the form of keeping their jobs at the expense of jobs for folks in other regions, and ignoring an economic opportunity and possibly retarding progress in general . . . . . . well, that seems to me really inefficient. And kind of morally dubious, too. ------ erikpukinskis _COTS has proven that under the right conditions, a properly incentivized contractor — even an all-American one — can develop extremely complex systems on rapid timelines and a fixed-price basis, significantly beating historical industry-standard costs._ If the "right conditions" include having Elon Musk as CEO, then "proven" is probably a reasonable word. ~~~ Alex3917 Exactly. Don't get me wrong, this article is extremely inspirational. But I doubt if there are more than a couple dozen people in America talented enough to pull this off. And, similarly, the vast majority of people in the government aren't capable of recognizing who the people this talented are, or if they are then they are unable to act on it. ------ bcl SpaceX gives me hope that we can become a space-faring nation once again. The added bonus is that it is private industry doing it, not the behemoth bureaucracy that NASA has become. ------ olalonde I don't want to sound too pessimistic but the trend in China is towards more free market capitalism whereas the opposite is happening in the US. Of course, trends can change and China is still far behind in terms of economic liberty. ------ burgerbrain That 300Million figure to develop Falcon 9 seems stunningly low. Fascinating stuff. ~~~ hugh3 I've always wondered why rocket development _should_ be nearly as expensive as NASA makes it sound. It's mostly a plumbing problem, surely -- pump the fuel to the right place and let it burn. I'm sure there are a few added complexities, but the tricky bits were all figured out decades ago. ~~~ dman Winning the world 100m is just about running faster. A Nobel prize is won if you think just a little bit harder... Pushing the envelope has always been heroically hard and always will be. ~~~ rwmj SpaceX aren't pushing any envelopes. They're just doing what has already been done for decades, but for a lower price. Edit: Instead of downvoting, how about replying? There are only 3 clauses above, so you can just say which one of those clauses is wrong and why. ~~~ dman Do you consider the IBM PC something that pushed the envelope? Sometimes disrupting an industry by making its products available at a dramatically lower cost is just as much a push to the envelope in the real world as a new discovery. (Other examples include firms like 23andme etc) ~~~ rwmj Look at the comment I was replying to[1]. The author of that comment was using "pushing the envelope" to mean running faster in the 100m dash or winning a Nobel prize. Disrupting an industry, as SpaceX are doing, is extremely worthwhile, but no one has ever argued that the IBM PC was some sort of breakthrough in computing, or represented progress in programming techniques (quite the opposite in fact, it was cheap and took many shortcuts, resulting in the horrible situation we have in computing today). [1] <http://news.ycombinator.com/item?id=2523927> ~~~ pg At the time, the IBM PC was very impressive compared to the other microcomputers available. ~~~ Someone The way I remember it, the main thing it had going for it was that 'IBM' tag. Its graphics were worse than that of the 4 year old Apple II, its speed was only a little higher (certainly way of from what the 1:4.77 clock speed ratio would make you think; both ran at around 1 MIPS). Yes, it handled more than 64k RAM and was 16 bit-ish, but very impressive? Not in my memory. ~~~ maxharris The original 5150 PC had a wonderful keyboard. We'd consider it very heavy and loud today (each key had a spring beneath it, and made a very audible click when pressed), but compared to the other keyboards at the time, it was easily the best. ------ adnam It's funny, but this is the _opposite_ of what happened during the 1950s space race. Russia, having less cash to spend, contracted work out various bidders, whereas america established the massively centralized NASA. ~~~ JoeAltmaier And Russia killed and maimed hundreds in their pell-mell race to the moon. So it was cost-effective and politically expedient, sure. But there are towns still expunged from Russian maps that were blighted by that irresponsible program. ------ spartanfan10 Though I really don't like the idea of an "Us vs. Them" mentality in global development (it's been commented many times that this is not a zero sum game, there doesn't have to be winners and losers like in football), this article is inspiring. Congrats to Elon and SpaceX on their wonderful innovation. ------ jmarbach This is an inspiring mark of American spirit that has seemed to escape our minds amidst international business pressures. I'm grateful that we have hardworking leaders such as Elon who take risks when others won't, and are dedicated to living their dreams. ------ jmtame I didn't see this before, but the SpaceX office tour is pretty awesome: <http://spacex.com/multimedia/videos.php?id=26> ------ breathesalt "Beat" China? Why not work together? ~~~ timsally Because as much as we'd like to pretend otherwise, there are significant ideological differences between the US and China. China just enacted a 3 month ban on all spy dramas on TV [1] and I'm about go home and watch Casino Royal with a bottle of scotch [2]. And as JFK says, _our leadership in science and in industry, our hopes for peace and security, our obligations to ourselves as well as others, all require us to make this effort, to solve these mysteries, to solve them for the good of all men, and to become the world's leading space-faring nation._ [3]. This may seem nationalistic to you, but I think JFK is right. [1] [http://www.nytimes.com/2011/05/06/world/asia/06briefs- China....](http://www.nytimes.com/2011/05/06/world/asia/06briefs- China.html?_r=1&ref=china) [2] Citation not needed. [3] <http://er.jsc.nasa.gov/seh/ricetalk.htm> ------ lostbit Fine. This is definitely good news. It proves a company is doing a great job, it gives hope and inspiration to other business try to be innovative and bring back the American spirit. But what will happen to space programs if American economy goes into a harder crisis? People will probably vote not to launch anything, not to look at the sky, but to spend money on land issues instead. My big concern is regarding the end of the dollar as the world's reserve currency. That could bring many succesfull companies down, specially those on American markets only. China can be a big issue to America if it starts no to believe in dollar currency anymore. In this context, beating China on innovation at Space programs might not mean Americans won. ------ VB6_Foreverr That blog post is written in such an unpretentious way.

Over the course of a year I probably made $5, obviously far below the $100 payout limit. I kept it open and now that I DO have a site that makes money, I eventually got that money from Google. In other words: keep the account open if you care about what happens to the money advertisers pay google? ------ RobGR I doubt an Adsense account has much value by it's age. I would close it.

Twitter sets max user caps for 3rd party clients and limits rates - rkudeshi http://thenextweb.com/twitter/2012/08/17/twitter-4/ ====== danilocampos Basic truth: New technology is driven by early adopters, who then influence their less tech-savvy pals. Happened with Google, happened with the iPhone, and it happened with Twitter. So now that the obvious is out of the way – we'll look back one day and see this as the day Twitter fucked the dog. They've made a decision that motivates the very core of early adopters who embraced Twitter to move on. Yeah, they have to make money. They've convinced themselves the experience must be entirely under their control to do it. Okay. And maybe that's so. And maybe they'll squeeze some pennies out for awhile. In the meantime, there's a group of folks who first jumped into Twitter during the days where you weren't chained to their mediocre user products. They'll start the move to a better network. And one day, everyone will look around and see all that's left on Twitter is the glitter gif morons and big brands with more money than sense, just as happened with MySpace. ~~~ pkulak MySpace didn't die because they pissed off the early adopter geeks. They pissed off everyone. And everyone left. If Twitter just becomes the place where hundreds of millions of people follow hundreds of celebrities while also looking at ads, I think they're okay with that. ~~~ citricsquid I don't think Myspace pissed anyone off, it was more that their product didn't make any sense. In my experience people didn't leave Myspace for Facebook because they "hated Myspace", they left because Facebook was a better product that met their needs. I don't think Twitter should be concerned unless someone builds a better product. ~~~ danilocampos > I don't think Twitter should be concerned unless someone builds a better > product. Which is inevitable. Their clients are crappy, otherwise there wouldn't be a third-party ecosystem to piss off in the first place. Which means their only defense is network effects. Which means it's probably a bad idea to motivate all your early adopters to find and grow the network that unseats you. ~~~ citricsquid I think you're really underestimating the value that "normal people" provide to Twitter, I would bet that the majority of Twitter users (that are active) are not "early adopters", but "normal people" that follow celebrities and talk to their friends. I left high school a few years back and the majority of my Facebook friends are ~19-20, almost all of them use Twitter and not a single one could write a line of code in any programming language, nor could they give a damn about whether or not Twitter is open to developers. Take a look at the Twitter trends list if you want proof that Twitter caters more to "normal people" than it does "technology" people, here's the #1 trend as I type this: <http://twitter.com/#!/search/%23NameATurnOn> Yes, their only defense is their network (which is, in my opinion, their "product"), but the majority of their network is not going to leave because of their developer relations. Twitter are safe as long as an alternative doesn't exist and they provide value to their users. Twitter aren't stupid, they're not going to be enacting this plan if the majority of their users use third party clients. I suspect the majority of people that do use third party clients are those using "value adding" third party clients, like Hootsuite, and those that use Hootsuite are the people that get value from Twitter's network (for example marketing people) so if Hootsuite shuts down they're not going to quit Twitter, they're going to move to an official client. ~~~ w1ntermute If the percentage of 3rd party client users are small, then why would they even bother enacting this change in the first place? > Twitter aren't stupid Oh come on, that's not an argument. There have been countless examples throughout history of companies (in tech and otherwise) that have done stupid things that have directly contributed to their demise. There's no reason to assume that Twitter won't end up like them. ~~~ citricsquid Small as a percentage is still millions and millions of people and tens of millions of requests. ------ aaronbrethorst Wow, fuck you very much, Twitter. I really wish this had happened when App.net was still raising their $500k. Even though I still don't think App.net will work out, I would've still chipped in out of spite towards Twitter. This is ridiculous, and I'm going to figure out how to get out as soon as possible. edit: I put my money where my mouth is, as it were: Success! Thank you for joining App.net! You will receive an email confirmation to complete the signup process. Your plan is Developer Tier for $100 per year. You're in line to join the alpha with username: @aaronbrethorst. ~~~ abraham App.net got over $800k in funding and still has a large amount left from picplz.

As in several years at their current burn rate. ~~~ illicium 1 week to write a Twitter clone, several years to blog about it. ~~~ jordanthoms They can just use the rails tutorial, right? :-) ------ ctide Congratulations Dalton Caldwell! Who could have known that Twitter would just hand you the entire game with one stupid maneuver. ~~~ dm8 It makes things harder for developers. But it doesn't affect end-user at all. Twitter already has eye balls, celebrity users. Average joe doesn't care if Twitter has 100k user cap for third party client. End-user experience is getting better day by day. Ask someone who is not tech savvy is on Twitter. ~~~ jonursenbach Users will care then their favorite application no longer works. ~~~ dm8 They will curse the application developer and choose the next best application. In this case, it will be Twitter. ------ pavel_lishin Please read the original article. This very unfairly summarizes the actual blogpost. The limit isn't 60 hits per hour. It's 60 hits per hour per endpoint, and only for some endpoints. The user limit is 1 million users for certain api endpoints, and 100k for others - and if you need more than that, they would like you to reach out to them. Oh, and also, all current clients are grandfathered into the old terms. Please examine the bandwagon carefully before jumping on it. ~~~ aaronbrethorst From <https://dev.twitter.com/blog/changes-coming-to-twitter-api>: "If your application already has more than 100,000 individual user tokens, you'll be able to maintain and add new users to your application until you reach 200% of your current user token count (as of today) — as long as you comply with our Rules of the Road. Once you reach 200% of your current user token count, you'll be able to maintain your application to serve your users, but you will not be able to add additional users without our permission." Translation: 'Fuck you, 3rd party Twitter clients.' They'll still cut them off at the knees when they hit _at most_ 200,000 users. Edit: I kept reading the blog post and it got better: _That upper-right quadrant also includes, of course, "traditional" Twitter clients like Tweetbot and Echofon. Nearly eighteen months ago, we gave developers guidance that they should not build client apps that mimic or reproduce the mainstream Twitter consumer client experience." And to reiterate what I wrote in my last post, that guidance continues to apply today._ In other words, 3rd party Twitter clients are dead. Not today, but next year they're dead as a doorknob. Edit 2: Thanks for the clarification on the '200%' thing. I think the net result is still about the same for Twitter clients in the end. They'll be EOL'd by their developers and increasingly ignored by users. ~~~ rlivsey Translation: 'Fuck you, 3rd party Twitter clients.' They'll still cut them off at the knees when they hit at most 200,000 users. Nitpick - it's 200% of what they're at now, so if they currently have a million users they're good for up to 2 million. ------ zethraeus It's rather frightening that the _only_ example that they give of a user facing service in the appropriate 'quadrant' is Klout. ~~~ ceejayoz Good: Klout Bad: Tweetbot, Storify What is this, Opposite Day? That stopped being fun in kindergarten. ------ rksprst In the tweet display guidelines: "No other social or 3rd party actions may be attached to a Tweet." <https://dev.twitter.com/terms/display-guidelines> Wonder if that means 3rd party apps can't add actions to tweets like "assign to a user", "translate", "schedule a reply", etc. That might just kill major functionality for apps like HootSuite, CoTweet, Radian6's Engagement Console. Or, since it's under the guidelines for individual tweets, are tweets in the timeline excluded from that limitation? ~~~ whamill Tweets in a timeline, on the Twitter feed in the web client, all have the retweet/quote/reply/favourite actions per-tweet so I would expect that they mean each and every tweet displayed anywhere. ------ ljd "It is also limiting the rate on its API per end-point, meaning that most individual clients will be limited to 60 calls per hour instead of 350 calls per hour. " If you can't raise revenue, reduce expenses. That cut is significant enough to reduce their rate of growth of monthly expenses but probably not enough to reduce their rate of user growth. Probably not a bad move for them. With press releases like this Twitter is App.net's new best friend. ~~~ gjulianm <i>Most individual API endpoints will be rate limited at 60 calls per hour per-endpoint. Based on analysis of current use of our API, this rate limit will be well above the needs of most applications built against the Twitter API, while protecting our systems from abusive applications. There will be a set of high-volume endpoints related to Tweet display, profile display, user lookup and user search where applications will be able to make up to 720 calls per hour per endpoint.</i> 60 calls per hour are only for certain endpoints, probably creating lists, tweeting... It's really rare that an user uses so much of this kind of resources. The endpoints that are used the more (viewing tweets, look up an user, etc) are actually less limited than before. ~~~ kmfrk Maybe they just hate the crazed Bieber, Glee, and Twilight fans out there with over 20k tweets to their name like the rest of us. :) It could suck for live-tweeting events, though. ------ waterlesscloud Remember the Great Twitter Strategy Document Leak of 2009? [http://techcrunch.com/2009/07/16/twitters-internal- strategy-...](http://techcrunch.com/2009/07/16/twitters-internal-strategy- laid-bare-to-be-the-pulse-of-the-planet-2/) What happened to those plans? They seemed so smart... ~~~ aaronbrethorst New management, new strategy. ------ _lex Twitter is making it very unappealing to build on their platform, since developers have to effectively give up a large chunk of autonomy and trust that Twitter's business model won't change again, and that Twitter won't suddenly start competing with them. And anyone who's paying attention knows that that's exactly what Twitter will do, since they don't have a clear, believable business model, and they've done it(destroyed their 'developers') before. ------ guelo I use Twitter via their official apps, I have tried some of the third party apps but haven't really been impressed. After all this time it didn't seem like the app ecosystem was coming up with anything really innovative besides slightly different ways of organizing the feeds. ~~~ dustyreagan That's because they bought the cool third party apps like the TweetDeck and Tweetie, and have since begun shunning third party developers. In short, the official apps were third party apps, and now no one wants to make any additional Twitter apps because Twitter has become hostile to developers. They've closed the door on third party inovation for their platform. ~~~ masklinn > like the TweetDeck and Tweetie Don't you mean Tweetbot or something? Tweetie was bought by Twitter, rebranded to be the official Twitter client, and in no small part gutted and left to rot (gutted for the mobile version, left to rot for the desktop one). ~~~ RKearney >> That's because they bought the cool third party apps like the TweetDeck and Tweetie >Tweetie was bought by Twitter That's what they said. I think you misread that post. ------ fudged71 I finally got really into Twitter this year. Sad to see them being so restrictive with their platform. Maybe App.Net isn't such a bad idea after all. It's amazing how poor the first party clients for Facebook and Twitter are compared to the functionality and rate of development on 3rd party apps. Maybe paying to be a part of a less restrictive network will be worth it in the end. I just hope they can get a big following with a bunch of apps integrated with it. ------ px1999 I'm having trouble trying to figure out who Twitter's trying to target with these changes - and can't figure out if: 1\. They want to corner the advertiser & business market - ie it's an attack on Hootsuite etc 2\. They want to lock out competitors from pwning them on search (Google/Bing incorporating [good] twitter results into their searches would IMO be devastating to twitter - particularly if they didn't embed intents / hueg links to twitter everywhere) 3\. They want to own the ecosystem so that twitter clients don't cross-post to Facebook/G+/app.net/favourite social network here 4\. (I don't think this is likely) - Twitter thinking that they can somehow squeeze an extra couple of bucks out of each user if they're on an official client via advertising or something similar. . Each of these seems plausible to me, but all of them essentially involve twitter holding customers/data/users hostage which doesn't seem like a great strategy. Is there some angle I'm missing here / reading too much into? ~~~ jchung I was also trying to figure out the business rationale for this move. Their 2x2 chart gets us relatively close to understanding their strategy. Here's what it looks like: \- Twitter doesn't want to own analytics for business or consumer players. \- Twitter doesn't want to own engagement for businesses. \- Twitter DOES want to own engagement for consumers. This seems pretty counter-intuitive to me. Since businesses are the ones who actually pay twitter cash, I would have expected them to try to own the whole left side of their chart, and leave developers to create new innovations for the whole right side of the chart. What would you have to believe in order for this to be a good idea? Some possibilities: \- Twitter thinks that developers will ruin the consumer experience, slowing their growth. \- Twitter thinks that businesses won't pay them unless consumers are tweeting on twitter.com \- Twitter doesn't think that analytics or business engagement services will be lucrative enough for them to invest directly in. \- Twitter thinks that if the developer community spends its effort in the top-right, it will distract the community from innovating in the other three quadrants, where Twitter wants to see more development to unlock more business-driven revenues (This one is a _real_ longshot, but I'm trying to be comprehensive) \- Twitter doesn't care about users tweeting or consuming tweets if they aren't on twitter.com (I'm still struggling to figure out why this is bad for twitter -- any thoughts, HN?) ------ jot How would you feel if Google announced that you could only access their services using Chrome? What does it take to activate the antitrust lawyers? ~~~ SoftwareMaven I wonder if "antitrust" and "monopoly" talk are HN forms of Godwin's Law. Before Twitter would be remotely concerned about antitrust, there would have to not be a place with more users that you can talk about your cat's lunch to your heart's content. Facebook has more to fear than Twitter does. ------ mhartl This is the kind of thing that happens when you don't have a business model. ------ dave_sullivan I wonder if a p2p twitter would be possible. I guess there would be real storage/timeliness issues, but twitter always struck me as more rss replacement than anything else, and I'm not sure it makes sense to have something like that run by one company. I think twitter is a cool concept/application, but I'm not sure it will ever be a great _business_. ~~~ runn1ng I have a genius idea how to make a p2p pseudo-twitter which I have shared with only one person yet, but why not share it now on HN (maybe someone can build it instead of me, since I don't have the time at the moment because of school stuff). Basically, what you need to solve in something like p2p twitter is: how to authentificate the user, how to send the message around, how to archive the message that it is not lost. Now the genius idea: all of this is _exactly_ what bitcoin solves. Bitcoin already has mechanisms for authenticating. Bitcoin already has mechanisms for sharing messages (altough it is called "transactions"). Bitcoin has a mechanism for archiving those messages (it's called "blockchain"). And the kicker - bitcoin already has an ability to enter arbitrary data into the transaction. (sure, not much, but about the 160 letters tweets have.) You just add it into the script and add OP_DROP; since the transaction including script is signed, noone can just remove it. My idea was to hijack the already existing bitcoin infrastructure and hack Twitter-like P2P messaging thing on top of it; let's call it "bitmessage". How would sending a "bitmessage" look like? Well, you can, for example, send money from your address to the same address (send money to yourself) and add the wanted string into the script. You can then look for a message of a given user (if you take bitcoin address as an ID of the user). Now of course, this wouldn't be free for long (if it catched up). Right now, bitcoin miners take just anything the P2P network throws at them, but if the network was flooded with people sending money to themselves with a message in script, they would just throw these away so it doesn't enlarge the already giant blockchain. However, you can add fees to any transaction. If you add fees high enough, some block miner will eventually take your "bitmessage" and add it to the blockchain. Would the resulting thing be equivalent of twitter? No, it would be slow (it takes about 10 minutes to get transaction to blockchain) and it would most likely not be for free (if it catches on, miners will throw away the messages with low fees). On the other hand, every message would be recorded _forever_ , without _any_ chance of anyone deleting it, censoring it or getting your IP address. Also, the Bitcoin seems to be going strong and doesn't seem like it will go away any time soon, and the infrastructure is super-strong. I want to hack a prototype... maybe... one day. ~~~ lukeholder Just a tip. When you start a sentence with "I have a genius idea" people will not think it's a genius idea; or at least judge your comments to an unreasonably high standard of your own creation. ~~~ runn1ng well, I didn't mean it _that_ seriously, but thanks ------ state It seems to me that the kinds of applications they are trying to prevent from existing are precisely the ones that they could learn the most from and could provide them with the most new users. I also don't see how this action actually wins them that many more eyes. Are there really that many third party Twitter apps out there? ------ jmathai I anticipate a flurry of parodies on their use of the term "flock" except away from Twitter and not towards. ------ WALoeIII There could be a revenue stream in here. They're limiting how many free users an application may have, but I would expect they could charge Tweetbot to have more users. Tweetbot could simply build this cost into the software. ------ jonknee I have seen a lot more pushes trying to get me to advertise lately (tons of sponsored tweets). I wonder if this is related to their revenue push--knock out their competitors and lower API costs. ------ DigitalSea Can you smell that? It's the smell of victory, the smell of Dalton Caldwell lighting a Cuban cigar in celebration of Twitter driving basically every single 3rd party developer over to App.net. ------ fufulabs This removes their duality of being a media / service play. This is highly beneficial to Twitter itself as well as to a new service/platform aiming to be a pure microblogging piping service. The only loser here are the Twitter app developers and startups which are faced with a now limited channel to promote their apps. ~~~ dannygarcia I don't see how this benefits Twitter. A large amount of users rely solely on a dedicated third party client. If those apps lose the ability to provide the same reliable service, then Twitter (as a platform) will also be affected. ~~~ danilocampos "Only" 23% of users. Still, I could see the argument that some users are better than others and the most engaged ones are more likely to get a third party client. Which means either Twitter loses those users eventually or coerces them into using their first-party offerings. ------ imrehg I really want to like Twitter, I really do. So many possibilities, so many interesting services built on top of them, it would be a great centre for "online identity", a main front to communicate with friends and audience. Except when they do these kinds of things, and I wonder how on Earth it makes any sense besides "because we can"? ------ ashbrahma Anyone know how to check the number of users that have authenticated the apps on the twitter dev portal? ~~~ abraham Currently you can't. They used to show those numbers but dropped it, I think, for scaling issues a long while ago. Maybe Twitter will bring it back. ------ bane So why are they doing this? My guess is to drive users to their clients, so that they can start displaying ads and gather revenue. 3rd party clients won't display Twitter's own ads so there's no way for the service to collect on that. ------ mehulkar Winter is coming. ~~~ dm8 Which winter are you talking about? Twitter has been tightening the strings for a while now. ------ moe R.I.P. Twitter *06/2006 †08/2012 ------ galactus I guess twitter thinks it is big enough to stop worrying about pissing third party developers off.

Status.net somehow didn't deliver, although I guess I could reevaluate.

Ask HN: Was Snapchat the first app of its kind? - Xcelerate One of my problems in developing apps is that for every idea I think of, I do a Google search and almost always find an app that already exists for such a thing. Sure, there's always the potential to create a better app that does the same thing, but at least for me, coming up with a novel ideal seems to be difficult.<p>So I am kind of surprised that Snapchat has taken off in the way that it has considering such an idea probably crossed my and many others' minds.<p>I can think of three possibilities: Snapchat was an original idea; Snapchat developed the concept of temporary photo sharing much better than any competitor; this current period in time is simply the point at which an app like this acquires popularity.<p>Thoughts? ====== vitovito It sort of depends on what you think Snapchat does. If you think it's _temporary_ photo sharing, who knows. If you think it's _expiring_ content sharing, there's been imageboards and textboards forever. Given that Twitter "expires" content off your stream and off your own profile after 3200 tweets, Twitter could be considered that sort of model. You can probably imagine how you could make a custom Twitter client that works like Snapchat but uses Twitter as its platform. You might wonder if there'd be a market for that. But all of these over-simplify and over-generalize what Snapchat does. The correct answer is #4, the one you couldn't envision. If you were surprised, it means you don't understand why people use it, which means you're not thinking of it in terms of the _problem it solves for them,_ but only as an idea with an arbitrary, coincidental implementation. Snapchat solves a problem for a segment of users and solves it very well. It is both a _solution_ and has a _well-executed design._ You need both, and then you also need marketing and network effects and traction and luck. To better understand why Snapchat is the current communications darling, you might look into danah boyd's research into how teens use social networks, or this recent anecdotal exploration of one US 10th grader: <https://medium.com/product-design/d8d4f2300cf3> Don't start with an idea, start with a problem that you have evidence exists, then develop a solution. ~~~ Xcelerate Great explanation. > means you don't understand why people use it I think this is a problem for app developers in general. I can't predict what a typical app user will really like because I'm not one of them. It's kind of funny because even though I really love developing new technology, I find that I don't use any of the really popular things (Twitter, Instagram, etc.). So instead I have to imagine "if I was a normal person... what problem would I be trying to solve?" A lot of times I guess wrong. (I remember how happy I was when I developed an icon editor when I was young. The feedback I got was very positive but I got very little of it.) Solving my own technical problems isn't going to get me any business at all. ~~~ vitovito I should be clear: I've never used Snapchat, and I am not a 10th grader, and the world current 10th graders live in is not the world I grew up in. But I understand the problem it solves. I'm not "imagining" it's a viable solution for a hypothetical problem: I've read the research that explains the problem teens have and their mental models of their social interactions and can see where Snapchat fits in appropriately. That's what research is _for._ It's why Steve Blank says to get out of the building. You don't have to imagine. Leave your office, get away from your laptop, spend time in other places and discover problems that people have, and then see if there's a market for a solution. Incidentally, the work a founder does in developing a product through customer development is most of the same work a product designer, user experience designer, or interaction designer has to do. If your product already makes sense, it saves us a lot of time and effort. This other link from HN earlier today, about what Amy Hoy taught this person about starting a business, which sums it up pretty well: <http://justinjackson.ca/amy-hoy/> Good luck with your apps in the future.

There’s also one attendant on hand to help the tech challenged. So no, it isn't fully automated. Just the front staff. That's not nearly as interesting, and the headline is intentionally misleading. ~~~ kagamine It's essentially a drive-thru that you walk through and there is only one person to complain to when you find a bug in your salad. I don't see how this is anything "new" at all. ------ todd8 In 1964 my parents took me to a restaurant in New York called an Automat (see [http://cityroom.blogs.nytimes.com/2012/06/17/revisiting- the-...](http://cityroom.blogs.nytimes.com/2012/06/17/revisiting-the-era-of- automatic-dining/)). It had a wall with little windowed doors that would open for a few coins. Inside were dishes of food that one could take to your own table. Off topic aside: we were in New York to go to the 1964 World's Fair. All I remember of that was the IBM pavilion. There I wrote handwritten digits on a card (in little boxes) that a machine read and printed out. Even then I was fascinated with computers. ------ vinay427 >As it’s all automated, be aware that the restaurant only accepts credit cards. No cash. I understand the allure of credit cards for their target marker, but has the author not heard of vending machines, ATMs, and other automated cash handling systems already in place? Those need regular maintenance, to be fair, but considering there's a regular staff of cooks that wouldn't be a problem. ------ crdoconnor Not exactly a new concept: [https://en.wikipedia.org/wiki/Horn_%26_Hardart](https://en.wikipedia.org/wiki/Horn_%26_Hardart) ------ bullsbarry So for those of us on the east coast, this is what Wawa has been doing for years now.

The entire place consisted of one wall of frozen foods and another wall of microwaves. Not completely automated but pretty minimal human involvement since you had to microwave your own food. ------ JoeAltmaier So 'fully automated' means 'partially automated', i.e. just the order-takers are missing. Still a kitchen; still busboys; still hand-made food delivered to a cubby with your name on it. I guess 'fully automated' means 'lousy service' now. ------ sdm This is a pretty common thing -- except the glass door cubby hole thing that your food gets put in. You find in a lot of Taiwanese restaurants machines at your table for ordering, requesting things like water and utensils, etc. Yes they have people who bring these things out to you, but otherwise it doesn't sound too different. What's new here? If it was machines preparing the food the title might be more deserved. ------ Pinatubo San Francisco plans to raise its minimum wage to $15 in a couple of years. Expect to see more businesses that follow this model. ------ technofiend Considering the recent troubles with Listeria Blue Bell had I would be very worried if all the food was automatically prepared.

(how spartan a name for a luxury brand!) edit: Ah nevermind, re-reading the lexus wiki page states that: _The etymology of the Lexus name has been attributed to the combination of the words "luxury" and "elegance," and another theory claims it is an acronym for "luxury exports to the U.S." According to Team One interviews, the brand name has no specific meaning and simply denotes a luxurious and technological image._ ------ kia This is nice _Six Apart – company co-founders Ben and Mena Trott were born six days apart_ ------ TeMPOraL It's interesting how many companies were named after founders. I get the feeling that today it's no longer the case for technology companies. ~~~ saraid216 I honestly have trouble deciding if this is a good thing or a bad thing. Good: It's less ego-centric. Bad: It's more idea-centric. I mean, the YC mantra is that founders matter most, no? ~~~ dredmorbius I think on balance it's bad. Naming an enterprise for the founder/founders helps wire in more of the critical DNA, but in a way which _doesn't_ tie you to a specific product or service. It's tricky to do this with a more generic name. This gives both an anchoring identity and flexibility to grow. It tends to imply a long-term view by the founders as well: why attach your name to something for which you've got an explicit exit strategy? By way of counter-examples, "IBM" (International Business Machines) turns out to be a really good, generic, but still applicable and adaptable, name. "Apple" has worked fairly well. "Xerox" is tied to a specific duplication method. "Polaroid" grew and died with a specific photographic process (though "Land" doesn't seem to have helped much in this case). From recent tech memory, "VA Research" (later "VA Linux") was named for its cofounders. ------ libria So Wendy's is named after Dave Thomas's daughter Melinda.

China puts final touches to world's largest telescope - yexponential http://www.aljazeera.com/news/2016/07/china-puts-final-touches-world-largest-telescope-160703080236077.html ====== gjkood Can someone explain the following to a relative layman to the science of radio astronomy? a) How much more can this accomplish in comparison to the well known Arecibo Radio Telescope? b) How is a fixed parabolic dish radio telescope different from a radio telescope array like Karl. G. Jansky Very Large Array? What are the relative pros and cons of one over the other? c) How do you 'steer' the telescope to look at different parts of the sky? I understand the dish is fixed, but the feed horns can be repositioned, but I don't really understand the physics/math behind it, other than the focus is changed. I also assume there may be some massive supercomputers doing the data analysis of the vast amounts of data collected. Any details of the back end computing infrastructure dedicated to this effort? ~~~ amluto > a) How much more can this accomplish in comparison to the well known Arecibo > Radio Telescope? It's bigger and therefore collects more light. This lets users see dimmer targets. It could also have a different field of view, different wavelength sensitivity, and/or different instrumentation. I don't know details of this new telescope. FWIW, Arecibo is also a radar (it can transmit pulses and look for reflections). I don't know whether the new telescope can do that. > b) How is a fixed parabolic dish radio telescope different from a radio > telescope array like Karl. G. Jansky Very Large Array? What are the relative > pros and cons of one over the other? Very generally, single dishes will have much nicer point spread functions, so the images are more like camera pictures. Aperture synthesis images can have weird artifacts. Huge dishes like this are also huge and this have more collecting area than many small dishes combined, anthough the big arrays, in contrast, have much, much better angular resolution. > c) How do you 'steer' the telescope to look at different parts of the sky? I > understand the dish is fixed, but the feed horns can be repositioned, but I > don't really understand the physics/math behind it, other than the focus is > changed. Imagine a big mirror on a wall. If you stand in a different place relative to the mirror, you see a different image in the mirror. ~~~ saboot Could you clarify on the difference between a single radio telescope having a better PSF, and an array having better angular resolution? What's the difference between those two qualities? ~~~ amluto There are a few ways to have good angular resolution with a weird PSF. Even with just optics, you could build an instrument with a PSF that has a narrow central peak with a big ring around it. This would be great for separately resolving nearby objects but bad for resolving a single object against a background of many nearby objects. For aperture synthesis, particularly strange things happen. If you take a quick (no rotational synthesis) exposure with a huge 3-antenna array, for example, you only get 3 choose 2 = 6 degrees of spatial freedom, but you get very fine angular resolution. In practice, you do "map making", in which you try to extract specifically the parameters you care about, but if you try to make an actual picture, you certainly can't fill in your whole field of view with tiny pixels, since you can't get past the small number of degrees of freedom. My personal favorite example of aperture synthesis is the images of Saggitarius A*. You can get incredible detail, but the "images" are made under certain assumptions and don't represent actual individual pixels with reasonable PSFs. ------ Trombone12 Telescope without qualifier implies optical telescope, title should be changed to clarify that it is a radio telescope. ------ ourmandave _The "Five-hundred-metre Aperture Spherical Telescope", or FAST, is the size of 30 football fields..._ This thing will look adorable when the Square Kilometre Array comes on line in 2020 and starts pumping many Petabits of data per second.

It doesn't need a long time on-source to make an image. So it is "FAST". A telescope array is basically a huge structure with _lots_ of holes in it. As the Earth rotates, the elements of the array sweep out arcs. That fills in some gaps. So even with a relatively bright source, you might need to wait a while before you fill in enough to be able to discern the details. So a big, single dish is "FAST". Array elements are spread over thousands of meters. You get great _resolution_ , like a microscope on the sky. But you also get all these diffraction patterns. Since you know the shape of your array, you can mostly solve for this, but it's a pain in the ass. ------ copperx Someone ought to make a shouldwelearnchineseyet.com page. ------ wollstonecraft Please do not call the Trisolarians.

It's almost like harmful has lost meaning because of the complexity of the systems of which to it refers. Everything modern is ridiculously complex, even if it looks simple. You can't state that a single thing in a complex system is harmful without forcing yourself to re-evaluate the entire construction of the rest of the system, in which case you can either (A) determine that there is no alternative solution, or (B) the system must be altered in some other way (in which case now multiple things are equivalently harmful. Since (B) happens so frequently, this means many parts of every system are harmful precisely because the system isn't perfect yet (and every part can be minorly adjusted so long as other parts of the system are adjusted - and this latter part is never discussed (probably because the complexity involved is actually complex and someone else would be like 'dude, that's also harmful - your solution has side effects'))). If it was easy to implement new things people would do that instead of complaining. There's a good reason things are the way they are and not some other way. ------ jflatow I stopped drinking the REST cool aid years ago, for pretty much the same reasons. It's not that HTTP APIs aren't useful - of course they are - it's the religious adherence to REST doctrine that is harmful. I take the author's point to basically be, "do the simplest thing that makes sense for your use case, don't worry about how RESTful it is", which I totally agree with. ------ merb RESTful doesn't mean "JSON" only. It never did and never will. People using RESTful APIs with XML. Also i don't get many things he is saying like: > multiple parameters for each criteria, e.g. age=10&name=John&company=Foo > (but how to implement OR operator?) I mean seriously? How would one represent a filter in a GET URL... there aren't many solutions. Also CRUD by Design? What are you talking? REST is not a fucking standard, it's just a way to create your API, you are totally free, to use CRUD or not, your API's could still be within REST if you not use CRUD at all. You could even make REST APIs with GET and POST. Everything he writes has nothing todo with REST. It's just a design decision. ~~~ andrewstuart2 RESTful also never meant HTTP. REST is literally just transferring resource state explicitly, via some mutually-understood representation of a resource. JSON just happens to be much more readable as well as pretty familiar for anybody who's written code in a C-like language, and especially familiar for JavaScript developers. ~~~ jazzyk >RESTful also never meant HTTP NOt in its original spirit, but it was developed in parallel with HTTP 1.1 (see [https://en.wikipedia.org/wiki/Representational_state_transfe...](https://en.wikipedia.org/wiki/Representational_state_transfer)) and uses the same verbs (GET, POST, ..) as web browsers to transfer data. I agree with the posters who say that just using 4 verbs is CRUD-oriented and semantically just not rich enough to support often complex business operations. ------ akoumjian This is such a non-issue. All you have to do is look at how successful RESTful APIs have been this decade. It's easy to consume, which is really the number one priority if you actually want anyone to use your API. Anyone who has built an API will tell you that REST gets you 80% of the way, and if you need some transactional business logic the world will not end if you add a few non-REST custom endpoints. ------ strictnein > "By building all these levels of abstractions we forgot that web is really > asynchronous" Uhh... nope. No one forgot that. Least of all the people he's chiding. Any decent Javascript / Front End Dev is acutely aware of this. Overall, this is perhaps the most unpersuasive clickbait I've read in a long time. It is amusing, though, to see a Java dev complain that REST isn't enterprisey enough. That's not a negative, good sir, that's a selling point. ------ skazka16 Our team is currently working on building a pretty big internal API from scratch. I took a look at some popular APIs (twitter, facebook, twilio, etc.) as a starting point. All of them has its own structure of the response, as well as the way you interact with those APIs, i.e. one may use `order` field to sort the resultset, while the other one prefers `sort_by` instead. There is definitely nothing wrong about that. But most of us like standards. We try to follow specifications as much as possible, at least to make things more predictable. Long story short - we ended up with [http://jsonapi.org/](http://jsonapi.org/) \- a complete specification for building JSON-based APIs. It supports such things as pagination, filtering, sorting, relationships, etc. All of us could implement it all very easily, but only God knows what is on the mind of an engineer, i.e. whether he likes /endpoint.json vs /endpoint?format=json. ------ moistgorilla Can articles with the words "considered harmful" in the title (or the article itself for that matter) be banned? It's almost always a low effort way to get votes by taking a popular technology and finding some flaws to write an article on. ~~~ andybak Ignore the title and take each post on it's merits. Personally people complaining about 'considered harmful' irritates me more than said articles. I thought this article was OK - certainly good enough to skim read for 5 minutes. Neither an upvote nor a downvote from me. ~~~ moistgorilla The problem with considered harmful I'm having is that so many low quality articles are using it in their titles and it really says nothing about the content other than somebody thinks some technology is bad. ------ nine_k A nice article, the key ideas can be scooped by reading headlines. REST has its limitations, but it has one nice advantage: it uses a very well- understood, totally ubiquitous, firewall-piercing protocol. I suppose it's still a huge win for any public-facing, moderate-load service. One can use compact (non-JSON) data representation and even compress headers to save bandwidth. ~~~ slantyyz I found this headline odd: "Bloated, human readable format that demands extra compression" Is human readability a main reason for using JSON or is it a beneficial side effect? I always assumed (rightly? wrongly?) that the reason for using JSON was that it uses Javascript's native object format and therefore much easier to serialize/deserialize and debug at the browser level. ~~~ nine_k Human-readability means low density: ASCII only uses 7 bit of 8, and most characters, like letters or digits, use only 6. Nobody in their sane mind would `eval()` a JSON received from network, so parsing is required in any case, JS or not. A combination of lists and maps (maps being just a special-form list of pairs) can be represented in a much more compact way, especially numbers. Thrift and Cap'n Proto are definitely more compact _and_ as fast, or faster, to parse. I still suspect that in many cases, HTTP headers can be comparable to the message in size. A high-efficiency protocol would create a connection and avoid re-sending this information with every request — but good luck taking it through certain corporate firewalls. ~~~ slantyyz I totally get that there are better ways and security pitfalls with JSON. My assumption was more related to the intent behind choosing JSON for REST, not so much related to the actual implementation(s). ~~~ nine_k Sure, JSON is easy and intuitive. ------ clavalle This just in: one particular technique is not good for every use case! Most of these complaints boil down to REST is not complex enough to capture more complex interactions. But that is its strength -- yeah, there might be some tweaks to make but if you run into a RESTful interface it is easy to get your bearings. If you need something with more meat, pick something else. That said, shoehorning problems into a limited number of return codes with pre-existing specific meanings is an inherent problem with the whole REST approach, I'll give the author that. It is almost never a good fit. ------ josephscott <blockquote> Of course JSON has one (literally, one) tremendous advantage - it's human readable. </blockquote> I was surprised he didn't mention ease of use inside JavaScript. ~~~ jpollock You're not supposed to eval the strings, that way leads to xss. Since you're supposed to parse it no matter what, there's no difference between JSON and any other format. ~~~ bwy Umm. I have no clue how you can say this. In JavaScript, JSON is unquestionably the easiest format to use. It may or may not be the same to parse, say, JSON and XML. But how is xmlDoc=new DOMParser().parseFromString(booksXml); newatt=xmlDoc.createAttribute("edition"); newatt.nodeValue="first"; x=xmlDoc.getElementsByTagName("title"); x[0].setAttributeNode(newatt); as easy to use as JSON.parse(booksJson).title.edition = 'first' ? ------ Yhippa Short of the service provider giving you a library to access their code I prefer REST over SOAP for integration work I've done. REST in my experience forces better documentation and interaction between the service provider and client. I've worked with way too many SOAP services where some dev from 8 years ago wrote the service and nobody at the company wants to go anywhere near it to modify it. On top of that there is nearly zero documentation or if it exists it's very poorly done. With REST I feel I'm forced to interact with the creator which in my experience also drives better documentation. Because who wants to answer all of my usage questions :-) I have never run into HATEOAS in the wild but it sounds pretty cool. I hope to get to try out a service that implements that one day. ------ maxehmookau Harmful to whom? You don't like REST. That's cool. REST has actually been very useful. ~~~ vezzy-fnord This is kind of a thought-terminating cliche, though. Not that a lot of "considered harmful" essays necessarily have much substance, but actually pointing out that a lot of popular software is architected in a harmful manner and reinforces negative feedback loops, antipatterns and wrong conceptual frameworks is a legitimate thing to say in general. Dismissing such criticisms with "It works for me," "If you don't like it, don't use it," or "Who cares about X? I just want my Y to work!" is annoying and by definition anathema to any _technical_ discourse. They're vapid emotional arguments. ~~~ cholantesh I would rather see a discussion of how a potentially destructive mechanism could be improved, particularly one as ubiquitous as REST. But I imagine a lot of these essays are not particularly well thought out; they're just an expression of momentary frustration that the author won't hold a month or even a week after publishing. ------ sneak I frequently wonder why json-rpc isn't more of a thing. I've always rather loved it. ~~~ mands I agree - JSON-RPC is simple to use, parse and understand. Plus I feel it makes more sense when you are triggering computations remotely rather than querying. At StackHut ([http://www.stackhut.com](http://www.stackhut.com)) we're hacking on a platform that takes code you've written and hosts the API in the cloud over JSON-RPC. We think it's pretty cool and would love to hear from others doing interesting stuff with JSON-RPC. ------ mcguire " _There are plenty of well-established binary protocols that are both easy to parse and use little memory, e.g. Protocol buffers, Avro or Thrift._ " I'd just like to point out that none of JSON, Protocol Buffers, Avro, or Thrift are _protocols_. They're serialization/unserialization formats/libraries/frameworks of greater or lesser tonnage. Whether they suck or not largely depends on how they're used; if you're tunnelling all of your communications over HTTP, you might want to do something HTTP-friendly. " _Not to mention Swagger, the de facto standard for REST documentation, officially claims such approach is "not per design" \- and sticks to fixed URIs._" What? (One of the great downsides of REST is that most of the tools that claim to support RESTful designs, including JSR311 and apparently Swagger (I've never used it) simply _don 't_.) ------ muaddirac > Talking about documentation, purists claim that the only piece of > information API should expose is the root URI, e.g. www.example.com/api. > Everything else, including allowed methods, resources, content types and > documents should be discovered via HATEOAS. And if URIs are not officially > documented but instead should be discovered, it implies we should not rely > on hard-coded URIs in our code but instead traverse the resource tree every > time we use such API. discoverable != must be discovered This is a misconception and criticism I used to have. However, it's a misunderstanding of the point of HATEOAS - the point isn't that you can't use hard-coded URIs, but that any given URI should be reachable by traversal from the root URI. In other words, it's fine to keep a bookmark to your favorite article, just make sure you can get to that article from the homepage, too. (I guess I would say modulo redirects as well) ------ richmarr I belong to the static typing camp... REST, static/dynamic typing... all decisions like this are a cost trade-off. There aren't really two 'camps', there are just comfortable positions on a scale, places where people are acclimatised to the trade-offs by their experience. ------ batou I agree with this to a point. I just built an API over HTTP, ignored all the REST rules and separated everything into commands and queries. Commands are POST and do something. Queries are GET and get something. I need to write this up. Schema is hell with JSON etc. I don't get how you can enforce something like this cleanly in a language like JavaScript under node.js or something without piles of assertions or some weird meta-format. I'm barely managing with an informal Also JSON is a crapfest for transferring data. Need something better than that over HTTP that is strongly typed with strong schema and has flexible binary formats other than whacking a base64 encoded string in an object or using multi-part mime. And then you're back at RPC and protobufs or something similar. Perhaps that's the answer. ~~~ robinhowlett Are you describing CQRS? [http://martinfowler.com/bliki/CQRS.html](http://martinfowler.com/bliki/CQRS.html) ~~~ batou No, CQS. CQRS is slightly more complicated and decouples everything via a service bus model along with a massive software ghetto lead by Udi Dahan who I personally despise. An excellent marketer but a poor engineer. I've cleaned up two companies who bought into that idea (event sourcing, service bus etc). Simply a command is something mutative. A query is something not mutative that returns information. There is no further specification other than that. It doesn't mandate a bus or event queue or publishing model nor whether or not the commands are synchronous or asynchronous. ~~~ gregyoung4321 CQRS does not involve a service bus (though people like to sell them). This sounds like some people were led down very bad paths. Using event sourcing and a service bus together is frankly retarded. Greg ------ danpalmer The benefits of REST come when making public APIs that can be discovered with HATEOAS. People aren't doing that much yet, but I do hope it catches on, because we're not going to reach the next level of interaction between services until it (or something similar does). I think the title misses the point a little, or at least generalises too much. REST is not harmful, it's incredibly powerful when used for the right thing. However, REST is not the correct technology choice for internal or high performance APIs. ------ reklis I actually agree with you on static-typing and am a huge fan of binary protocols but using "no standards" around anything is a weak argument that everybody needs to just stop. If you don't like the fact that there are no standards with a particular tech, go out there and MAKE SOME. Show people how to do it right, document it and propose it. Get some buy in. Don't just sit around going "oh woe is me, no standards" ------ dpweb Is HATEOAS generally considered good? I recently had to integrate to two corporate systems. One, the API used typical GET, POST, PUT, etc.. The second (before I knew the term applied to this) provided a single URL whose response was needed to describe the other operations. I remember instinctively hating the second. Now MY code has the burden of translating these into the specific calls. However, now we are version proofed. ------ sigsergv Not all business/domain logic is document-oriented. You can map any api to “documents” but result will be horrible usually. There is an excellent book — “RESTful Web Services Cookbook” by Subbu Allamaraju, it covers all aspects of practical REST API and trains very useful sense of REST applicability. ------ justizin Since nobody can agree what RESTful is, and RESTful services tend not to follow any particular set of rules, indeed to the extent that most RESTful services aren't really RESTful, it's hard to get past the section titles in this as being anything other than an exhausted straw man. ------ mmilano I was expecting to see an alternate suggestion for communication via client- side browser based JS apps. ~~~ mands JSON-RPC always works well and is quite simple. I often find it easier to just use JSON-RPC and clearly mark which methods are remote than to try and fit my remote semantics into correct HTTP verbs and status codes. ------ clessg Ugh, can't read it because of the scrolling. Not sure what that's about. ------ xwintermutex I agree with his problems with status codes.

Cameras are about to get a lot smaller - spuz https://www.economist.com/news/science-and-technology/21724796-future-photography-flat-cameras-are-about-get-lot-smaller ====== wallflower > He was holding a small device in his hand, the size and shape of a lollipop.

But once you have enough perspectives to create a decent 3D model, you can generate as many fake perspectives as you like. Also, there are obvious downsides to panopticons. But none of that matters, I guess. We will have the cameras _and_ the fakes. ~~~ coldtea > _What good is video evidence, if it can be faked?_ Even better: what good is video evidence if few care? Consider officers shooting black people. There are several videos of that, but does it show any sign of stopping? They even walk off without any repercussions at trial... And, conversely, when people do care, no extra evidence is needed. ~~~ Shivetya Actually people do care, especially since there is video. what they still don't care about that would probably need video as well is the staggering amount of black on black shooting. however as a society are we willing to give up that much privacy the moment we step out the door, where anything and everything could be a recording device. then again if we are drowning in being observed do we in turn find more freedom? ~~~ mirimir With as many cameras as we already have, there isn't much privacy anywhere, unless we live alone.

They then go on to tell you what would be necessary to have their device equal a present day sensor in a phone, but they haven't made one yet. In fact, no estimate is given for when this technology might be competitive with CMOS sensors. The article just points to his previous work as proof he can get some of his ideas to market. Relevant XKCD: [https://www.xkcd.com/678/](https://www.xkcd.com/678/) I am excited by advances in camera technology, but this headline is peddling research as a pending disruption to the industry, and I don't see any evidence of that in the article. ~~~ regularfry He's saying he can make a commercial sensor in 5 years. Now, that's admittedly not saying it'll be in phones in that time, but when it works it won't just be competitive with CMOS sensors, it'll do things they aren't capable of. ~~~ orbital-decay There are planar Fourier capture arrays, which are also lensless, can be implemented with existing CMOS process and seem to be better by every metric than this. AFAIK they are currently being evaluated for eye tracking sensors which aren't sensitive to resolution (128x128 is enough) but need to be flat. There are also single-pixel compressed sensing cameras, which can be made lensless as well and are limited by the optical modulator specs. The problem with lensless sensors is always the computing power required to reconstruct the final image. ~~~ regularfry Admittedly I'm reading between the lines here, but I suspect that these don't need computationally expensive reconstruction. The reconstruction is done entirely by setting up the delays correctly on the input sensors, then the image is formed by simple interference. You'd read the image off just like an ordinary ccd. ~~~ vel0city From the article: "He concedes that there are challenges: improving the optical performance of the elements; suppressing spillover effects between different signals in the device; and honing the algorithms that calibrate the camera’s performance." The line of "honing the algorithms" is the complexity orbital-decay is referencing. These types of sensors do need computationally expensive reconstruction to generate images we're used to seeing with traditional optics and sensors currently found in many consumer devices. The filtering and focusing work the lenses do still needs to happen. These sensors essentially rely on complex math to replace the finely ground glass. ~~~ regularfry Those algorithms are already very well understood from radar and sonar, though. It's not like he's starting from scratch. And I'd take issue with the characterisation that they need "complex math to replace the finely ground glass" \- what replaces the glass is the analogue photon detection, delay, and amplification channel on the front end. My suspicion is that the only "complex math" is done calculating the delays before capturing the image, not doing the reconstruction (again, unless I've missed something unique about moving from GHz to THz). ------ ChuckMcM This is very much on the path I've seen in software defined radio (SDR). I am particularly interested to see when they invert atmospheric interference in real time. A telescope or spotting scope with a co-linear laser visible to the circuit should be sufficient. Then no shimmering heatwaves in the distance, just a clear picture. ------ leke Some ingredients for a always recording society... \- Super cheap and gigantic capacity storage. \- Wireless network like 5G. \- Wireless charging. \- Nano cameras. I think there was a Black Mirror episode about this. ~~~ stefanpie Well there was white bear which was more of a philosophical debate and then there was Most Hated in the Nation which I think really hits home the development of small new technologies such as cameras and the consequences of keeping their power and security unchecked. ~~~ swashbuck1r There was also The Entire History of You - where everything you see is recorded and can be played back at any time - leading us to hyper-focus on details from the past rather than experiencing the present. ------ amelius Could this enable a light-field camera?

Once it's working, competing with a 35mm system "should" (famous last words) be a matter of scaling up the number of elements to match the lens size. The thing is, once that happens, it's got a huge advantage: it doesn't need any other lenses. At all. Any "lens" you could want is a software configuration away. ~~~ leemailll is there already a model on sale? Like lytro? ~~~ spuz No, the technology demonstrated is only capable of imaging 8x8 pixels.

When you put a whole array of them you will be able to do various scans of light signals to simulate the camera pointing at different direction, or fisheye, telephoto effects without the need of tilting or moving the surface of the array. The underlying computation relies on the ability to calculate and control the timing of signal travelled from each antennas, plus some classic signal interference and phasing issues. An 1cm x 1cm array will contain 1 million such couplers which would create a similar sized image as an iPhone 7 rear camera, but since there is no lens involved, the camera can be made a lot thinner. ~~~ mtgx Using the Brave browser with the block scripts option enabled seems to work, too.

Dell XPS 13 Developer Edition (Linux) Review - Lio http://arstechnica.co.uk/gadgets/2017/01/dell-xps-13-ubuntu-review-2017/ ====== overcast These are definitely the awesome laptops Apple should have made. I just really don't want to give up macOS. I've literally put this thing back and forth into my cart, twenty times by now. But there is just too much I'm giving up environment wise. Either I go with Windows, and lose unix, or I go Linux, and lose everything but unix. That's why MacOS works for me, and I'm sure others. It's what Linux should have been by now, a hybrid Windows/Unix experience. Apple is really pissing me off, forcing me even to contemplate this. I KNOW Linux isn't Unix. ~~~ passivepinetree What's getting in the way of buying the XPS 13 and dual-booting it in order to have it both ways? Sure, you couldn't use both at the same time, but that seems like it'd take care of most (of at least my) use cases. ~~~ aceperry You'll probably need a larger hard disk to accommodate both operating systems if you dual boot. I prefer to run virtualbox/vmware and have both running side by side while using the best tools/software on each platform. ------ kag0 Does anyone know if the XPS 13 with linux suffers the issue where you can't rest your thumb on the bottom of the touchpad like a button [https://bugs.launchpad.net/ubuntu/+source/xserver-xorg- input...](https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input- synaptics/+bug/1026046) ? This issue has been my bane, and the biggest reason I haven't upgraded from my old thinkpad (has dedicated mechanical buttons). I would have thought there would be a resolution by now since more and more laptops do away with the dedicated buttons, but I've never found one. ~~~ kminehart I'm on my XPS 13 right now, on Arch Linux using xf86-libinput, thumb rested on the bottom left of the trackpad ready to click. Moving my finger on the trackpad towards the top moves the cursor. Using two fingers (with my thumb rested) scrolls the page. However, if I use my thumb to move the cursor first, this doesn't work and instead scrolls the page. Hope that answers your question. ------ jvehent An interesting review would be to compare this XPS13 with the upcoming Lenovo Carbon X1 as a Linux laptop. ------ evacchi I'll bite the bullet and be that guy. What about dual monitor support? What about suspend/resume? Do WiFi and Bluetooth work without issues? ~~~ CityWanderer I've run it with one monitor, two would be hard since it only has a single USB C and I don't have any monitors that can daisy chain.. if that's even a thing. The issue is that Linux doesn't play nicely with having different pixel densities on each monitor. You can try to make it scale, but then apps appear in different sizes depending on which screen you open them on. It's pretty horrible, so I run the laptop at half-res (1600x900) so that it matches the monitor and everything is the same size. Suspend/resume works fine. I've had to restart the network-manager service just once to get WiFi to refresh. Otherwise it's fine reconnecting when you come in/out of suspend. Other things: battery isn't great but I don't use it away from a desk. On the first couple of days the Ubuntu Software Centre kept crashing; I think it's fine now but I don't tend to use it anyway. I disabled the Dell apt source because it was failing - I don't know if that was a one-off problem or it's just broken. But, I'm running Linux as my primary development environment again and it just feels _so good_ after a few painful months on OS X. ~~~ bardworx > But, I'm running Linux as my primary development environment again and it > just feels _so good_ after a few painful months on OS X. Can you expand on that, please. Why were you months on OS X painful? Just curious to hear the use case that caused this. ~~~ CityWanderer I've been using Linux of some flavour at home for the last 15 years, only straying onto Windows for gaming. I've been lucky to use Ubuntu at work for most of my professional career too (6-7 years?) - so it's what I know and what I'm used to. I started a new role a few months ago that forced me onto OS X and found physical and software issues. Physically OS X does not let you configure mice properly without installing third party drivers. Of course I ditched the "magic" mouse pretty quickly after my hand started hurting after a couple of days, but even with a normal mouse you simply cannot configure mouse sensitivity and acceleration properly - it cannot treat a mouse on par with what Linux or Windows will. You need extra drivers to even enable mouse buttons 3,4 and 5. The keyboard shortcuts hurt too, sometimes using Ctrl, sometimes using Cmd, but that could be just fighting 15 years of muscle memory - so take that with a grain of salt (but it indirectly caused more physical finger pain). Software-wise I don't know how objective I can be, but it feels faster/simpler to install software and things like the terminal are much better integrated - I can auto-complete git branch names on the command line for instance. Maybe OS X can do that kind of thing, but certainly not out of the box. To me, OS X feels like a 95% emulation of Linux, just that slightly bit lacking. Then there are the embarrassing things like I couldn't find the shortcut to go to the end of the current line.

I am asking since I am considering one of these machines. ~~~ arca_vorago Here it is or at least a variation in the past: [http://sprunge.us/DQhC](http://sprunge.us/DQhC) "By placing your order for Product, you accept and are bound to the terms of this Agreement."

Pretty standard overzealous boilerplate that companies get away with these days, but I don't like it so I don't agree to it. ------ chpmrc As usual "battery" is repeated multiple times in the article but without any number. When will reviewers understand that "battery life is not great" means absolutely nothing and replace it with something like "battery lasts 3 hours and 4 minutes while repeatedly streaming a youtube video in 4K on Chrome 52"? Notebookcheck is the only consumer tech website worth reading for the reviews (if you know others please share them) because of their precise, standardized tests from the display to the noise and heat produced by the chassis. ~~~ chias For what it's worth, my XPS 13 (with the 3200x1800 screen) lasts a good six hours on battery. I typically don't bother bringing the charger with me. The power brick on the charger is also very small and lightweight, making bring it with you not a big deal either. ~~~ sliken Despite the 22 hour number, dell only promises 12 on the 3200x1800 screen. Rather frustrating that they limit the good cpu/ram configurations to the 3200x1800 touch screen. So if you want more ram you are forced to switch from a matte screen that gives you 22 hours on battery to a shiny screeen that lasts 12 hours. ------ to3m Can anybody say whether the ANSI-style keyboard shown is the "Internal US/International Qwerty Backlit Keyboard" option that's available on Dell's shop on the website, or whether this place just got sent a US-spec laptop for whatever reason? The word "international" is rather worrying, suggesting it might have one of those upside down L return keys... ~~~ moreentropy US International keyboards have a AltGr key instead of right Alt and a € symbol on the 5 key. Afaik there are no other differences. ------ StavrosK This sounds like a great replacement for my aging MacBook Air, but, having been bitten by its non-upgradeable 4 GB of RAM, I'm wondering whether I should just get a 32 GB laptop. I think I'll spring for the XPS 15 in the end, since it has a better graphics card as well, and I could do some light gaming on it. ~~~ JamesMcMinn I'll be going for the XPS 15 too. I've been using an XPS 13 9333 from 2014 with 8GB RAM and recently I've struggling to keep things under that limit. The XPS 15 has the advantage that the RAM is user replaceable, and as I understand it, the 16GB model comes with a single 16GB module, so should be fairly cheap to upgrade to 32GB yourself if you'd like to save a few $ initially. ~~~ StavrosK You mean it has two slots but only one module? That's great news if so, it means I can just buy the 16 GB model and upgrade later, if/when I need the 32 GB (possibly replacing both modules). ~~~ DocG Last year XP15 (8gb) model has two 4gb sticks inside. Still, two easily accessible slots. ------ buckhx Anyone know how the XPS 13 2 in 1 is w/ Linux support? I don't think they have a DE for the 2 in 1, but thinking about snagging one for a light work/entertainment laptop. ~~~ kminehart The main difference in hardware between the DE and the non-DE is the wireless card, which isn't impossible to get working but definitely a pain in the ass. I can only imagine with the touch screen and tablet-mode combined it would be a tall order for out-of-the-box Linux compatibility. ~~~ szarecor For the previous version, DE used a different wifi card (intel for DE, otherwise Broadcomm), but I don't think that's true for this latest version. I think DE and non-DE both ship with the same Qualcomm "Killer 1535" ------ Hydraulix989 The keyboard is shit according to the reviews. Every developer needs a good keyboard. This is why I exclusively use ThinkPads, even if they aren't as good under Lenovo as they were before. ------ ld00d > What's more disappointing for some Linux fans is the fact Dell still uses > the Windows logo on the super key. It's the first thing I look for and most often the first source of disappointment.

Lenovo Just Released a New Laptop That Beats the MacBook on Basically Everything - jseliger http://www.slate.com/blogs/moneybox/2015/05/04/lenovo_s_13_inch_lavie_z_laptop_is_lighter_than_a_macbook_has_multiple_ports.html?wpisrc=obnetwork ====== akhalr Bait and switch title. Most of the comparisons in the article are contrived because the laptops being compared are very different types of machines. Even so, the article itself lists quite a few areas where the new laptop doesn't come close to beating the Macbook (e.g. battery life). All that is followed by the admission "I also haven't tested the LaVie Z in person, so it could be a crappy computer, who knows". ~~~ ratfacemcgee it really is a terrible article. "To pack it all in, the Lenovo laptop is thicker than the MacBook. Apple's offering is 0.52 inches at its thickest, whereas the LaVie Z is 0.67 inches at its thickest point. _But still._ " "The LaVie Z is currently shipping for $1,500 or $1,700 depending on which model you get, compared with the MacBook, which is priced at $1,300 or $1,600." "Lenovo only estimates six hours of battery life for the LaVie Z...Apple estimates nine hours for its new MacBooks." "Even if the MacBook is a superior product, it's not way out in front like the MacBook Air was."

Saudi Arabian Hackers Leak Credit Card Details of 400,000 Israeli Citizens - Ohadr http://pastebay.com/150288 ====== yuvadam I just gave a talk last week at 28C3 [1,2] about how all the personal details of Israeli citizens are up for grabs for anyone inclined enough to get them. I'm ashamed to see that we've learned nothing in the past 10 years. [1] - <http://www.youtube.com/watch?v=ow7cvZOzp6w> [2] - [http://speakerdeck.com/u/yuvadm/p/28c3-data-mining-the- israe...](http://speakerdeck.com/u/yuvadm/p/28c3-data-mining-the-israeli- population-census) EDIT: Israeli media now claims that 400K is an exaggerated number, and the actual number of leaked CC is much smaller. EDIT2: I'm gonna go ahead and publish a mirror list [3] for the leaked data and for affected accounts by email [4]. I might be affected and I prefer to know if I am ASAP, even if this means the data leaks more, which it will anyway. [3] - <http://pastebay.com/186092> [4] - <http://pastebin.com/EnY7E0Hw> ~~~ maayank what's the password of the rar inside the rar? the page referenced in the "readme" file is unavailable ~~~ runn1ng At least the file, hosted on hacked sites, called israeli.rar, is without a password. ~~~ maayank I downloaded one of the files yuvadam posted (not sure if it's the same one there now - the post was edited) and it had a password protected rar in a rar ------ waffle_ss I have a very hard time resolving how this type of attack could fall under the umbrella of Anonymous. Saudis specifically attacking Israel implies a nationalistic attitude, given their history. They also affiliate their hacker group with Wahabbism, which is a strict branch of Islam that most would brand as fundamentalist (and sometimes extreme). I can't really see the ideals of Anonymous coexisting with nationalism and religious fundamentalism. ~~~ pjscott It's inspired by the Anonymous style: find someone you dislike, attack their computers somehow (e.g. private information theft, DDoS, web site defacing), and brag about it online. The ideals are very different, but the method is pretty similar. ~~~ noduerme The difference being that the people involved wouldn't be aware there was oil under their feet if our country hadn't invented the market for it, told them it was there and given them the equipment to drill it. Left to their own devices, the only thing they'd be hacking right now would be the back end of a camel. What do you think the chances are that their brute force method wasn't one of a million snippets written by someone in the west? Or in Israel, for that matter? How about the computers they used to get on the network they benefit from, but didn't create? Reckon the intel chips were made in Israel? After all the petty bullshit, Saudis like to party too. The problem is their government and society is repressive as hell, and they're so scared to confront it, they have to go into this whole make-believe world where they act as heroes by attacking Israeli servers. It's pretty funny. I'm sure Israelis will recover. The Saudis on the other hand still live in a medieval hellhole where women can't drive a car... and this really doesn't do much to change anything. Their time and energy would be better spent trying to bring civilization to their own wasteland. [Edit] I should add, the fact that if you did this in your own country, you'd probably have your hands cut off, is a powerful motivation to go after somebody with more liberal values. ~~~ agilo Ironic how despite all this, the american government finds it fit to support this repressive regime, while demonizing countries like Syria where citizens (or at least women) enjoy greater freedoms. One could say it all depends on your stance vis-a-vis Israel. The fact of the matter is that, countries like Saudi Arabia, Jordan, Yemen, old Egypt, North Korea etc. have normalized or at least neutral relations with Israel (despite the hypocritical rhetoric to appease the masses), and hence are supported or allowed to have their way (even their bombs). I think this hacking incident is a mere accident, and the ruling Saudis will be quick to repress it and assure Israel none of this will happen again. ~~~ berntb >>demonizing countries like Syria How can you "demonize" that type of brutal regimes? What _more_ can you say about them? That Assad eats children? >>One could say it all depends on your stance vis-a-vis Israel. >>the ruling Saudis will be quick to repress it and assure Israel none of this will happen again Sigh, so Saudi Arabia is pro Israel? :-) [http://en.wikipedia.org/wiki/Antisemitism_in_the_Arab_world#...](http://en.wikipedia.org/wiki/Antisemitism_in_the_Arab_world#Saudi_Arabia) This is a model of what happens there without conspiracy theories: Saudi Arabia is _needed_ as an ally by the US. It is called "realpolitik" -- all countries, including democracies, use it and lie about it. (The difference with democracies is that they do support human rights, as long as it doesn't cost too much.) North Korea sells/sold nuclear tech to Syria/Iran; are you really claiming they have "neutral" relations with Israel? And so on... please don't write this kind of thing on HN. ~~~ rbanffy I would say this whole thread took a wrong turn with noduerme's deeply rude, ignorant, arrogant an plain racist post. We would all have gained something had it never existed. ~~~ ThaddeusQuay2 "We would all have gained something had it never existed." Fuck off, Mr. Wannabe Censor. Progress requires unfettered conversation of all types, not just the ones of which you approve. "... noduerme's deeply rude, ignorant, arrogant an[d] plain racist post." It was none of those things. What he said is basically correct, and it reminded me of 2005's Syriana, in which there was a conversation between Matt Damon as Bryan Woodman, an energy analyst, and Alexander Siddig as Prince Nasir Al-Subaai, successor to the Emir. NASIR: An ancestor of mine owned this bird's [falcon's] ancestor before Christ was born. Six more North Field blocks will be available for development. We would like to offer your firm the right to represent them. WOODMAN: If I were your economic advisor I'd tell you it's not the dumbest thing you've ever done, but it'll probably be the dumbest thing you do today. Probably. But why would you need an economic advisor? Twenty years ago you had the highest GNP in the world and now you're tied with Paraguay. Your second biggest export is second-hand goods. Followed by dates on which you lose five cents a pound. You want to know what the business world thinks of you. They think a hundred years ago you were chopping each other's heads off in the desert and that's exactly where you'll be in another hundred. So, yes, on behalf of my firm, I accept your money. <http://en.wikipedia.org/wiki/Syriana> I included the first sentence, about the falcon, because it shows that Nasir is proud of his people having been around for a long time, but that apparent plus is effectively countered by Woodman's observation about their primitive nature, and how the oil money is really the only thing keeping them from regressing. Sure, the film is fictional, but there is a lot of truth to be found in it. ~~~ rbanffy > Fuck off, Mr. Wannabe Censor I'm not one who wants to impose restraint on others. I merely suggest a little bit of tact makes dialog possible. Or, more important, that its lack may make dialog impossible. > Progress requires unfettered conversation of all types, not just the ones of > which you approve. It also requires the conversation itself, which may be rendered unproductive by the kind of comment made upstream. > it reminded me of 2005's Syriana, in which there was a conversation between > Matt Damon as Bryan Woodman, an energy analyst, and Alexander Siddig as > Prince Nasir Al-Subaai Is all your knowledge in Middle East affairs derived from a movie? ------ Ohadr Anonymous just declared that they are not responsible for this: <https://twitter.com/anonyops/status/153969476277248000> "We have no love for Israeli gov't but targeting 1000s for being Israeli? Sorry, you are not #Anonymous pastebay.com/148920" ~~~ runn1ng Heh. I like how Anonymous keep on repeating how are they "decentralized" and the only thing really needed to join is to call yourself Anonymous - and at the same time keep on telling trough semi-official twitter accounts, how this Wahhabi attack or that Stratfor attack was not official Anonymous and blah blah blah. Hypocrisy on hypocrisy. ~~~ pdeuchler I would argue that the purpose of allowing anyone to call themselves "Anonymous" places the group's identity on their actions, not who they say they are. It's kind of the whole point of calling themselves "Anonymous" and leads right into the "we are legion" bit. There is no individual, only the movement. However, by performing actions that are contrary to the Anonymous ideology the Saudi attackers distanced themselves farther from Anonymous than any name could ~~~ jonhendry But what is "Anonymous' ideology" if anyone is part of Anonymous? Maybe Anonymous should have chosen a different name. Other groups could then remain anonymous, without being assumed to be Anonymous. ~~~ runn1ng Well, actually, Anonymous didn't really chose the name - it was a joke made on default "Anonymous" username on 4chan. And it really grew somehow organically into this point. That's what I don't like about people saying "You are not true Anonymous". First hackers under the name "Anonymous" posted other people MySpace passwords on 4chan and put blinking lights on epilepsy website. And the whole scientology movement was first meant as a joke, as a reaction to the leaked Tom Cruise video. Really, people calling other people "not true Anonymous" are hypocritical. I think. ------ asjd This is the IP of the hacker: 188.75.86.66 (It's possible this is a bounce server, but geo locating it suggests against this.) I know because I was involved in cleaning up one of the hacks. (I have to stay anonymous, but my main account has more than 7000 karma.) In the one I dealt with they did not copy stored cards (because they couldn't), but rather added extra code that would email a copy of the details to the hacker as the order was placed. (So even with PCI compliance credit card numbers can still be stolen.) ~~~ 3pt14159 Right now, right this second edit this post. Get right of the karma count and remove the rest of what you posted besides the IP of the hacker. Word frequency analysis + knowledge of your karma count will easily identify you. ------ krembo My CC was in the list that the hackers published. Just canceled it... Does anyone have good arguments against leaving the files where they are now and not deleting them from pastebin/megaupload/...? Since the beast is already out of it's cage, there is no point in chasing it. It is even better to let the public d/l the file and try to find themselves if their card and other details like emails, passwords were stolen. ~~~ darklajid Do you have any idea where your card was leaked from? Can you share what card provider you used? I was already paranoid about credit cards before I came, now it's really affecting my blood pressure.. (nice username btw, learned the word here..) ~~~ krembo I'm not sure if they stole it directly from the sites (coupon site in my case) or from the clearance company. In any case it seems that the site who store the details broke the law by storing the CVV (not to mention that passwords were not encrypted..) ~~~ ceejayoz Broke the law, or broke the PCI standards? ~~~ krembo i think in IL standing in the PCI standards is a must for clearance comapnies. ------ darklajid I have an israeli credit card. I'd have liked to understand where this was leaked from. And - well - make sure that mine is not among them. Unfortunately (or fortunately?) the file isn't available any more. ~~~ Ohadr I also have three of them... I think once that file was online even for a few minutes, the card numbers mentioned in it are not safe anymore. It will be leaked again. If it's not some kind of provocation (files with false data) then this is a pretty big crisis. I'm going to have to monitor my credit card logs closely in the next few weeks... ~~~ krembo Since i found my CC details over there I assume this is not false data. Can we call it a cyber terror attack? ~~~ HotKFreshSwag I would call it black hat hacking, hacktivism or sabotage. I wouldn't call it a terror attack unless you feel terror when you realize you have to call your credit card provider. Lets save the word terror for things that terrify people like say bodily harm or death. ------ hack_edu Curious to see how the general consensus of Anonymous falls in line with this. Lets not forget the long history of black hats in Israel. ------ theunixbeard Interesting. I wonder, have there been other examples of religiously-motivated hacks on this scale? ~~~ nostromo Religious or political? I suppose in the Middle East the two are conflated. ------ usaar333 When I went to Israel a few years back I could not believe my eyes when I noticed that my entire CC number was printed on every receipt. I don't imagine online CC security being much better.. ~~~ eliben That was mostly fixed, AFAIK. Now only the last 4 digits are printed on receipts. ------ vsviridov I thought Anonymous were against corrupt politicians et al, and not just general populace :( ------ teyc Don't VISA et al require some kind of PCI compliance for storing credit card details? ~~~ jacquesm PCI compliance is worth as much as the party that signs off on you being compliant, in most cases that is you. Audits are few and far between, lots of places have shoddy security but claim they are Fort Knox. PCI compliancy is quite meaningless unless the people that implement it take their job seriously. That's very frequently not the case, it is just seen as a small obstacle in the way of doing business. ~~~ teyc Thanks. Odd that VISA would let the third party auditors get away with it, until they don't... which I'd hope so in this case. Related: [http://serverfault.com/questions/293217/our-security- auditor...](http://serverfault.com/questions/293217/our-security-auditor-is- an-idiot-how-do-i-give-him-the-information-he-wants) ~~~ rdtsc It is mostly to cover their behinds not really to protect your data. When it comes to litigation they basically want to point to a piece of paper with your signature on it and say "see they agreed to be compliant" it is not our fault, we did all we could. ~~~ teyc I saw an Australian company offering tokenising solutions for credit card transactions. Glancing briefly, they talked about replacing credit card number with "tokens" that can be stored on the customer's premises, while the actual card numbers are securely stored on theirs. To me it seems to be a sensible approach to reducing the attack surface or auditable surface. Is this what Stripe does? ~~~ rdtsc Visa has the "visa verify" and it is a web service that basically asks extra security questions during authorization. That works online only. Relies on the merchant to provide the extra security. Another thing is temporary one-use credit card numbers. My Discover card as that feature. Of course then it also relies on me to assess the risk of a merchant and go through the steps of getting that number. ------ desireco42 Just because is easy, it doesn't mean you should do it. Stealing from ordinary people even from nation that you feel so much hostility to, still it is wrong. ------ samstave Faction warfare. EDIT: I got downvoted, without a reply. So, explain how doing this sort of thing is not faction warfare? The details of israeli credit is leaked by anons from the house of Saud. This is clearly a faction issue. It is not likely government sponsored (though likely condoned) and as a religious rift exists between jews and muslims, the word faction applies perfectly. Jews, muslims, christians; all factions within religious zealotry. ~~~ jonhendry I think the term is 'sectarian'. ~~~ samstave A sectarian word for factions. Tomato Potato \--- Sectarian: of, relating to, or characteristic of a sect or sectarian limited in character or scope \--- Faction a party or group (as within a government) that is often contentious or self- seeking : clique party spirit especially when marked by dissension \--- You would be a fool to claim that sectarian skirmishes are not also political, given the widespread theocratic nature of governments under both muslim and jewish rule. In this case - this is an attack, while premised on the appearance of religion, is actually a theocratic/political-religious attack. ------ saljam I find it odd they call themselves “Wahhabis.” For starters, that term isn't something a “Wahhabi” would call himself. I've never been able to trace when it was first used. However, it's often used by western scholars to refer to “the Saudi guys” when classifying Muslims. Does anyone know more about this group? ------ gokhan > We have posted this message in pastebin, but it seems they have deleted the > file. That Stratfor dump with 75.000 card details is still on Pastebin. Why this one deleted and the other is still there? (I believe both should be deleted.) ------ pm90 Attacking the general (innocent) populace for the faults of their government/military? That's the definition of terrorism... and not activism. ~~~ rdtsc > Attacking the general (innocent) populace for the faults of their > government/military? Generally agree but with one exception -- in places were the government claims it represents the people and most people agree with that. Then everyone who votes basically shares the guilt of what the government does. ~~~ dvirsky Most democracies I know are usually divided between conservatives of some sort and liberals of some sort, who agree and nothing, and usually just over 50% of the voters if not less, agree with their government's policies. I totally disagree with the Israeli gov's policies and often protest them. Guess what? My personal info was inside those files (deprecated credit card and email though). Attacking citizens of democracies because they are inseparable from their government and responsible for its actions, is a common argument for terrorism, btw. ~~~ rdtsc Democracies (or just "advertised" democracies) can't have it both ways. They get to tell the world about their superior system of government where citizens have a say in how their government runs (sometimes they even invade others to impose this "superior" system on them). And that's great. But then there is the other side of the coin when the said govt. screws up, then citizens should man up and take responsibility. I am responsible for US invading Iraq and Afghanistan. If I am in those countries and I would be afraid for my safety (and rightly so). I didn't vote for it, and I don't think realistically people have the power and the voice in most advertised democracies. But then, one can argue, they are also responsible for now changing the system (and therefor the 99% Occupy stuff is happening all over, it is not about economy it is about who has the power, control and responsability). ------ shn too much fuss for something you can not verify. a)are they really valid identities. %100 of them? b) how do you know that these were done by Saudis? ------ billpg I've set up a site to check if your card was on the list. Just go to my site and type in your card number... ------ kingkilr Stay classy... ------ noduerme From what I can see, the real Anonymous at least has the balls to go after their _own_ government. Sure it's easy to hate on Israel, and these douchebags will no doubt get some props from fellow haters for their little hack, but if they had a pair of testicles between the lot of 'em, they'd start leaking info on the dictatorship they live in, rather than stealing credit cards from the democracy next door.

document.f.q.focus(); The Billion Dollar Line of JavaScript - jkush http://www.blogstorm.co.uk/blog/billion-dollar-javascript/ ====== vlad The author confuses correlation and causation. Google has been setting the cursor to the textfield since they were in beta and long before AdWords. I've done the same. It's funny the author neglected to consider that Google could have eliminated the I'm Feeling Lucky Button (try it) if they really wanted to give users a chance to make the "mistake." Actually, it's just a side-effect of making life easy for users. ~~~ jkush I totally agree with you vlad. I've always attributed the cursor focus as being just good user interaction and not some ploy for more ad clicks. ~~~ vlad Yeah! However, it is one of those great moments where one goes out of their way to make life simple for their customers, and then notices a pattern they couldn't have possibly deduced had they not implemented their idea. ------ Alex3917 There are actually a number of legitimate reasons for typing URLs into Google instead of the address bar. For example, public computers in foreign countries are often configured to redirect .com requests to the national TLD. So it's much faster to type amazon.com into Google than it is to figure out how to make Amazon.com stop resolving to Amazon.cn or whatever. ------ rwebb "At an average cost of $5 per click this adds up to maybe $500 per day in revenue for Google just for this one search. Multiply across 365 days and taking a very conservative guess that this happens across 10,000 different domains gives over $1.8 billion in yearly revenue for Google." clearly! ------ henning Google's revenues are largely dependent on the behaviors of inexperienced users, especially ones who can't tell the difference between text ads and actual content? No way! ~~~ rms When I want to immediately engage in a financial transaction, I always click on the Google ads because I know there I will find someone selling me something rather than useful pure information ~~~ henning Google's results for things often result in places to buy that thing rather than information about it, so I don't know if you're being sarcastic or not. ~~~ rms I was being serious, sometimes I do find the Google ads useful.

Why does the apple watch exist? Who knows - joering2 http://www.wired.com/2015/03/apple-watch-exist-dont-know/ ====== 27182818284 Of the people I know with Android watches, most like it for the ability to prioritize notifications. Every single one has said that. They can see if they need to answer some reminder, meeting, etc with a more gentle glance. With that, I'm smart enough to remember that I "didn't need a smartphone" when they first came out and resisted them before they eventually became part of my daily life. More to that point, I think it is pretty easy to imagine really neat things in generations II and III. Say, when you can use your watch to pay with a biometric confirmation that it gets from being on me. Or 2-factor auth the same way, or fixing the bugs the article mentions when calculating the harder health metrics like stress. Imagine the generation V that measures insulin and logs it. Etc.

The Maginot Line - devindotcom http://techcrunch.com/2013/08/25/the-maginot-line/ ====== revelation The image of the Maginot Line article in full resolution: [http://tctechcrunch2011.files.wordpress.com/2013/08/maginotl...](http://tctechcrunch2011.files.wordpress.com/2013/08/maginotlinearticle.jpg) Its better reading than all of techcrunch, so.. ~~~ Patient0 Interesting that they originally planned to have it cover Belgium too - if they'd actually finished it Germany would not have been able to go through Belgium after all. I wonder why they didn't finish it? ~~~ vonmoltke As I recall there were a few reasons. The two biggest ones: 1) The Belgians threw a shitfit over the French wanting to build a wall to seal in France with them on the wring side of it. They offered instead to allow the French to connect French eastern border defenses to Belgium's eastern border defenses, promising that if the Germans did decide to invade Belgium again that their line would hold. 2) The portion that was completed cost over twice what was projected. The Franco-Belgian border would have been harder to fortify than the Franco-German border, and considering the cost overruns on the latter portion the former started to look infeasible. ~~~ cstross Also worth noting: Belgium was traditionally neutral, having been set up as effectively a buffer state in the wake of the Napoleonic wars. The bloody quagmire First World War was in no small part precipitated by Germany's violation of Belgian neutrality, which brought Great Britain into the war on the Franco-Russian side -- the UK had committed as a guarantor of Belgian neutrality. So despite strong misgivings about German revanchism during the 1920s and 1930s, Belgium was also historically somewhat ambivalent about joint defense projects with foreigners. ~~~ walshemj But if they had allowed the British and French to advance to the defense line before the Germans invaded ww2 would have turned out very different. Part of the reason that the German blitzkrieg worked so well is the french and British forces where out of position. ~~~ cstross Yes, absolutely. And I note that these days Belgium is home to NATO's Supreme Headquarters Allied Powers Europe (SHAPE). They might not have worked it out after WW1, but after WW2 ... ------ ballard Strawman recapitulation of PHKs thoughts. Unfortunately, the conclusions are both wrong, and naïve at worst. Crypto that gets used has to be easy-to-use, MySQL style. I think a project like tcpcrypt is great example, in theory. Simple is good because the pain of setup has to be least. (Tcpcrypt is opportunistic encryption that needs no additional setup and is different from SSL.) Crypto does work. Snowden admitted as such. “Encryption works. Properly implemented strong crypto systems are one of the few things that you can rely on. Unfortunately, endpoint security is so terrifically weak that NSA can frequently find ways around it.” [http://m.techcrunch.com/2013/06/17/encrypting-your-email- wor...](http://m.techcrunch.com/2013/06/17/encrypting-your-email-works-says- nsa-whistleblower-edward-snowden/) (The last point is another form of the ancient security problem of taking steps to minimize chances of plaintext disclosure.) The cost to capture or recover plaintext should be much greater to the proportion of the potential value of the PT over the time it could cause damage. Just giving up is defeatist and expects that some future government made of fallible people would suddenly get enlightenment and act benignly. Never going to happen, there is too much money and power at stake. (USG fears its citizens but abuses power to crucify dissenters.) Encrypting almost everything is one immediate way to forcibly remove the possibility of abuse. Remember that even if (and that's a big "if") political sands were shifted one way, they would certainly shift back to a culture of secrecy and expedient Machevellianism. If you don't take reasonable measures to protect yourself, you don't understand what's going on or what works. There are no easy fixes, only defense-in- __depth __. Security is fundamentally an unending competition of gambits and countermeasures that will continue so long as people have secrets or desire freedom from intrusion. ~~~ eru > Crypto that gets used has to be easy-to-use, MySQL style. I think a project > like tcpcrypt is great example, in theory. Simple is good because the pain > of setup has to be least. (Tcpcrypt is opportunistic encryption that needs > no additional setup and is different from SSL.) The off-the-record (OTR) plugins for various IM clients spring to mind as easy to use. ~~~ Argorak Except that a lot of people never care about validating the peers fingerprint. "Hey, I am A, I am at another computer at the moment, hence then new keys." (I know this is somehow mitigated by SMP in libotr, but some clients have not implemented it yet, e.g.: [https://trac.adium.im/ticket/9768](https://trac.adium.im/ticket/9768)) ~~~ eru I found OTR's handling of that via shared common knowledge (e.g. Socialist Millionaire Protocol) quite pleasant. ~~~ Argorak Hence the reference that not all clients provide an interface to SMP, including very popular ones. ~~~ eru Sorry, my reading comprehension failed. ------ fauigerzigerk I think what we can achieve with cryptography is to force the government to use proper courts and due process instead of mass surveillance. I don't know why war metaphors are used for everything since 9/11\. The Maginot Line is completely irrelevant, because this is not a war where one party wins and one loses. It's a complex and ongoing political and social process. We can use technology to make long standing legal principles more effective and their violation more visible. ------ gruseom I read somewhere recently that the Maginot line has been unfairly maligned and that it actually did its job pretty well. Edit: this is the piece I was thinking of: [http://ericmargolis.com/2013/06/on-ne-passe-pas-the- unknown-...](http://ericmargolis.com/2013/06/on-ne-passe-pas-the-unknown- victory-of-the-southern-maginot-line/) ~~~ PhasmaFelis Yeah, my understanding is that the French knew very well that the Germans would go around; the Line was only meant to force them to detour through rough country and slow them down long enough for the French Army to mobilize. It failed because the Nazis used unprecedented tactics and technology to storm through Belgium and the Netherlands faster than anyone thought they could; the French Army still knew they were coming, but weren't able to mobilize fast enough to stop them. ~~~ rodgerd Also, the British forces that were supposed to be guarding the Western route into France folded quickly and retreated. "Blood, Tears, and Folly" contains exceprts from contemporary sources noting that the British determination to retreat was such that they prevented French troops from redeploying to their Western flank so as to avoid the French defence impeding the British retreat. ~~~ vonmoltke Additionally, the Belgian fortifications were not nearly up to the level of the Maginot Line, nor the level the Belgians boasted. They proved to be little more than a speedbump for the Wehrmacht. ~~~ pash The Germans also devised novel tactics to overcome the Belgian fortifications. In the initial attack on Eben-Emael [0], for example, commandos descended on the fort in gliders in the black of night and used newly devised shaped charges to destroy the heavily bunkered Belgian guns. Blitzkrieg itself was a new tactic, but its success depended on surprise, which the Germans achieved by sending their main mechanized force through the rough, wooded terrain of the Ardennes while feinting an attack to the north, through the plain of Flanders, where the Belgians and French expected them. That was a hugely risky endeavor, and the offensive would probably have failed if the German movements had been discovered during the several days it took to cross the Ardennes Wood. 0\. [http://en.wikipedia.org/wiki/Fort_Eben- Emael](http://en.wikipedia.org/wiki/Fort_Eben-Emael) ------ jpalomaki The article mentions " I was told yesterday (by Bruce Schneier, so I trust it) that the noise pattern from a device’s antenna can be used to fingerprint it, a side effect of high-precision wireless transceivers." My quick attempts with Google did not provide any good results. Does anybody have pointers to research about how feasible this fingerprinting is for example against modern cellphones? ~~~ AsymetricCom Modern cellphones have many, many other ways to fingerprint them that are more economic. I doubt what Schneier suggests would ever be used in anything other than military applications for the next 10 years. ~~~ rdl It's more of an issue for something like wifi, where you can trivially change MAC (and do host-level stuff to change the fingerprint of the rest of the stack). ------ Sagat This is perhaps off topic but my cousin is a tour guide in one of the villages close to the border with the Germans. Thanks to this I had the opportunity to visit some of the Maginot bunkers where the French troops waited anxiously for the invasion to come to their doorstep. A few rooms had their walls entirely covered in miniature Mickeys, giving the place an eerie and deeply melancholic atmosphere. The point of my post is that it feels really great that France and Germany are now allies, maybe even friends. You can criticize Europe a lot but at least we aren't fighting each other and hopefully won't do so for another century. Whenever I see Americans complaining about their country turning to shit I want to tell them to focus on the fact that it could have been so much worse. ------ dangayle I actually appreciate that article. Yes, it is written a little heavy handedly, but the point is sound. Sure, there are some smart/informed people who knew the actual power of the gov't to snoop, but by and large the "carbon copy" metaphor is dead on. Even here on Hacker News recently, there was an article about how the entire US nuclear armament is run through ancient computers and we chuckle. "Ha ha, you gov't people are stuck in the stone ages". Of course, they let us laugh. ------ unhammer "when a burglar comes through the window, do you put more locks on the door? Better to just acknowledge that we chose to live in a dangerous neighborhood." So they start keeping both the door _and_ the window unlocked? If that happened to me, I would 1) get better at keeping my windows closed/locked/barred 2) consider moving to a better neighbourhood.

[http://www.pewinternet.org/Reports/2013/Where-Teens-Seek- Pri...](http://www.pewinternet.org/Reports/2013/Where-Teens-Seek-Privacy- Advice.aspx) suggests the opposite. "in violation of the 5th amendment, likely, but how long until a friendly precedent on that account?" – so vote, speak out, do something instead of accepting the status quo. Who wrote this, Keith Alexander? ------ joseph_cooney I was amused to learn the Germans had built a similar line on THEIR side of the river, called the Siegfried line. ~~~ arethuza Defence of their Western border was very important when the Wehrmacht was active in the East - early in the war they really didn't have the men to attack in the East _and_ defend in the West so having fixed defences there was seen as very important. ~~~ joseph_cooney By the time they were active in the east, their western border was "The English Channel". This was the one they built before the outbreak of WWII. ------ snowwrestler It's written to be over-the-top, but I agree with the sentiment that we cannot fight government eavesdropping with "even better" technology. The only thing that limits the law is the law; the solution to our problems, at least in the U.S., must in the end be political not technological IMO. ~~~ unhammer The fact that law must limit law does not make "privacy technology" pointless. E.g. the dragnet would capture a whole lot more if no web sites used TLS at all, and three-letter agencies would have a lot easier time of it.

Lookup the current textbook for "Marketing 101" (or it's equivalent) at a nearby college. Go buy the book and read it, even if you don't take the class. If you have time and money, take the class. 3\. _The Ultimate Sales Machine_ by Chet Holmes. I'm deep into studying Chet's approach now, and his book has some great stuff on it. If you can, get hold of his videos from the program he did with Anthony Robbins titled "Ultimate Business Mastery System." You can safely skip the Tony Robbins part, but Chet delivers some good stuff. 4\. _In Search of Stupidity_ by Merrill Rick Chapman. 5\. _Positioning: The Battle for Your Mind_ by Al Ries, Jack Trout and Philip Kotler 6\. _The 22 Immutable Laws of Marketing: Violate Them at Your Own Risk!_ by Al Ries and Jack Trout 7\. _Re-Positioning: Marketing in an Era of Competition, Change and Crisis_ by Jack Trout and Steve Rivkin 8\. _The 22 Immutable Laws of Branding_ by Al Ries and Laura Ries 9\. _Differentiate or Die: Survival in Our Era of Killer Competition_ by Jack Trout and Steve Rivkin 10\. _Successful Business Research: Straight to the Numbers You Need - Fast!_ by Rhonda Abrams. This is good for learning about how to find the numbers you'll want to use to put together a first cut of a marketing plan. Think your "target market" is "screw, nut and bolt manufacturers in the southeast with more than 500 employees"? Then you need to know how many of those even exist, before you know if the market is even theoretically worth pursuing. Think your market is "adolescent girls in Massachusetts?" Then you might want population demographics and birth rates, etc. This is a good basic, (and cheap) book with some good pointers on how to get started on that kind of market research. 11\. _Marketing High Technology_ by William H. Davidow 12\. _How to Drive Your Competition Crazy: Creating Disruption for Fun and Profit_ by Guy Kawasaki 13\. I'm a big Seth Godin fan, I'd say read anything and everything by him. _The Purple Cow_ stands out in my memory as a particularly good one. _Permission Marketing_ is good as well. 14\. _The Cluetrain Manifesto_ Also, I don't have any specific titles handy (I'm out of town consulting right now, unfortunately, so I can't even walk into the other room and check), but just go to a good used book store near you (if you have one) and find a couple of cheap used textbooks on "marketing research" and "marketing strategy".

Ask HN: How long can you actually work standing up? - Vivtek Here's a question for people who are working at a standing-level desk - how long can you actually type while standing? Do your knees and feet get tired? I'm intrigued, but... I have to type a lot if I want to get paid. ====== ukdm Last year a hurt my lower back and was forced to stand up as much as possible to help the healing process for 6 months (sitting down puts 6x more pressure on your lower back than standing according to my chiropractor). I created a workstation that allowed my screen to be at eye height and keyboard/mouse to be at the right height for my elbows to be at right-angles. That was by far the most comfortable position to stand and type/mouse from. Later on I found having the mouse higher actually helped too with arm ache. As for how long I could stand for, the first week was not a problem. I was doing 8am-1pm followed by 30 minutes sitting down, and then 1:30pm-6pm without a break other than a walk to the toilet occasionally. From week two my legs really started to ache from the kneee down, I found myself leaning on the desk to take away the pressure. Investigating why this was happening I found it is to do with keeping your legs stationary as the muscles can cramp or just go stiff. The solution is to keep moving so a cheap manual treadmill should do the trick. The alternative of taking frequent breaks doesn't work as it breaks concentration. If you have to do this for a couple of weeks then you should be able to cope, if you want to make a "change for life" then come up with some way to keep moving while working. For those who do sit down all day and don't have back problems a word of caution. Sitting all day makes your lower back very stiff, but you won't notice this until you try to do something and hurt yourself. It may be a lifting task that an unstiff back could cope with. Taking time to exercise and stretch can save you such a disaster, I am healing well now, but still get twinges and have to be carefull. ~~~ jnorthrop "For those who do sit down all day and don't have back problems a word of caution. Sitting all day makes your lower back very stiff, but you won't notice this until you try to do something and hurt yourself. It may be a lifting task that an unstiff back could cope with. Taking time to exercise and stretch can save you such a disaster, I am healing well now, but still get twinges and have to be carefull." That is the right caution, but the wrong reason. A stiff lower back (lumbar) is desirable. You want to be mobile at your hips, and upper back (thoracic) and have the ability to keep the lumbar stable. When you lift something your lumbar spine should be immobile. You are correct that there are problems with sitting but it is that typically your lumbar is rounded so that you are weakening and stretching it all day long making it difficult to maintain proper posture when you lift something from the ground. A quick rule of thumb for mobility: Ankles (mobile), Knees (immobile), Hips (mobile), Lumbar (immobile) and Thoracic (mobile). Stuart McGill is a great resource for learning about proper back mechanics. Oh, BTW, I use a stand up desk and love it. ------ artlogic I recently (a week ago) converted my desk at my day job to a standing desk. It's easily the most ergonomic position I've ever worked in. I have noticed that just to keep my legs from getting stiff and my feet from getting sore I move a lot more throughout the day. At first this was slowing down my typing a bit, but I'm almost back up to speed. I also brought in a bar stool to lean on (not sit on) when my legs get a bit tired. I'd say I'm standing now for about 80-85% of the work day. I have noticed a bit of residual pain in my heels, but I just got a fatigue mat, and hopefully that will help. By and far the hardest thing to get used to had been minor lower back pain - which, from my research, is due to some core muscle weakness from - you guessed it - sitting too much. One of the best things I've found about standing is that it keeps me more alert and awake throughout the day. This is by far the most immediate plus, for me. The important thing to remember is to keep moving - change your position often. I have considered the manual treadmill route, but I'm a little concerned my co-workers wouldn't appreciate the noise. Walking in place seems to work just fine - but does earn me some odd looks. ------ rarrrrrr 8 - 10 hr days are no problem. I built up to that over a few weeks. Other possibly relevant factors: Switched to dvorak about 10 years ago. I'm in athletic shape and maintain a healthfull diet. I usually have a dead tree format book going, and take occasional breaks during the day to read, cook, exercise, take a walk, etc. Footwear makes a big difference. Minimal slippers were best. Anything with arch support makes my feet hurt after a few hours. ------ kylecordes I split my work about 40/60 between: 1) sitting down at my home office (nice wood furniture and decor the whole works) 2) standing at my work office (ugly but very functional perma-temporary standing desk) ... and don't have any problems at all. I type as long as needed, etc. However, I never stand still for more than a few seconds. (This seems to be a built-in feature of me, rather than anything I do intentionally.) ------ wbond I recently did a week long stint on a temporary standing desk before ordering new longer legs for my current desk. For the first few days my feet hurt after standing for an hour or so, however I did find that I felt more energetic throughout the day. I did have an odd feeling of being unsettled the first day, but after that I found it easier to focus, especially with the extra energy. By the fifth day the pain in my feet was significantly reduced. This week I've returned to my (fairly) ergonomic sitting desk setup and I've noticed posture issues and some discomfort in my lower back. My experience was that alternating short periods on a tall stool with standing provided the most comfort. The paper, "The benefits of sitting and standing to work" ([http://www.ergomotion.com.au/images/PDF/HFESA%20paper%202008...](http://www.ergomotion.com.au/images/PDF/HFESA%20paper%202008%20%20illustrated.pdf)), references a study in which 30 full-time bank tellers came to the same conclusion. Using a chef's mat can also provide some comfort for your feet. ------ johnyzee I have a motorized sit/stand desk, as is the norm here in Denmark (and Scandinavia in general probably). I have used these for five-six years. I tend to stand around half the time at work, which comes to something like three-four hours on the average day. If I have just done a long run or bike ride I might sit for the entire day as my legs and back will already be fatigued. The thing that makes me sit is aching feet. I suppose standing for a long time makes bodily fluids assemble in the lower legs, so after a while the feet start to feel a bit swollen and the heels get sore from having all the weight on them. This is alleviated by switching around from one leg to the other, but after a couple of hours I need to sit for a while (this is the reason a desk must be stand OR sit and not fixed to standing-only - you need the ability to adjust according to the situation.) ~~~ TrevorBurnham The norm? Really? Motorized desks are pretty rare here in the US. ------ imp I set up a temporary standing desk at home for my work at night and on the weekends. I didn't really have a problem typing for five hours at a time or more. However, after about three weeks, I was getting aches in my ankles and calves. I took down the standing desk soon after that. I felt like it was sucking up my energy. I think standing about 20% of the time would be ideal. ------ oscardelben I am now using an exercise ball <http://www.freestylemind.com/exercise-ball- office-chair> . I don't have a standing-level desk but the ball reminds me to stand up every once in a while. It's not exactly what you're looking for but it could be a cheaper alternative ~~~ docgnome I just started using one of these. Today is day 4. (The weekend was in the way, so it's consecutive day 2) So far the only real change is my back is hurting in a different place than with the cheap chair I had. (upper back instead of lower) I'm giving it till Friday because I've heard that back pain is normal at first mostly due to muscles being used that you weren't using before. ~~~ oscardelben I also recommend doing some back exercises if you can.

Motorola Droid hands on - alexandros http://www.boygeniusreport.com/2009/10/19/motorola-droid-hands-on/ ====== fjabre It really hope it does well and I love the direct marketing blitz attack on the iPhone... It's about time Apple had some real competition and Google is really the only company that can give them that.. I just feel bad for the established players.. They're going to have to watch as their core markets erode even further. ------ dmpayton A lot of the comments here seem to be about how ugly the device is. While I agree that they could have done a better job to make it more aesthetically pleasing, it's the hardware and software that are important. It could be a bright pink Hello Kitty phone, and I'd still want it. ------ nimbix Can you get a version that doesn't have 5 logos from 3 different companies on it? ~~~ swombat Yes, it's funny how the iPhone has no logo whatsoever on the front, and a subtle, elegant one on the back. If it's a great piece of design, you don't need to stick labels all over it. ~~~ sonofjanoh It's on the back so everyone can see it. It's a fashion statement to have an iSomething. Even here on HN you never (or rarely) read I have booted up my Asus or Dell or whatever BUT there's always "my Macbook" or similar. I like the underdog companies and I appreciate their effort and technology and I'm not buying into the iXXX hysteria. Apple was clever as it is being paid for being advertised. People pay sh%%loads for their products and they never ever forget to mention it in their discussions that they have one. Geeks are a very small percentage of the market so unless the phone is not a "fashion accessory" there won't be massive commercial success with it...but it will be a great thing I hope. ~~~ gohnjanotis I agree with your last point. It's too bad the Apple brand has been reduced to that of a designer fashion by the masses, or some kind of status symbol. It's like some people want a BMW just to impress the neighbors with a badge, while others can appreciate the level of engineering and the minds that went into the precision you can feel when you are driving it. I like to make purchasing decisions based on the competency of the company in making what they make, but unfortunately most people don't think that way so a phone like this doesn't even get a chance. ~~~ ektimo "while others can appreciate the level of engineering and the minds that went into the precision you can feel when you are driving it." I'd like to see a blind test for that. And who cares anyway if an expert can detect a certain "feel", other than for status? ------ maxklein I just need to look at this picture ([http://www.boygeniusreport.com/gallery/handsets/motorola- dro...](http://www.boygeniusreport.com/gallery/handsets/motorola- droid/?pid=3582#picture_nav)) to know that it's going to be another flop. Two things I believe someone should tell these companies: 1\. Don't save on your casing 2\. Girls don't like slide-out keyboards. The killer android phone will look like the razr and be pretty expensive. ~~~ davidw The thing about Android is that eventually, there will probably never be a phone that is as beautiful as whatever iPhone's doing, but that there can models for everyone's tastes. Something like this for the geeks, a slick, slim clamshell like you say, and all kinds of others. ~~~ roc Which is/was the same philosophy behind Symbian and Windows Mobile. Suffice to say, that flexibility comes at non-trivial cost. ~~~ fpgeek First, Android is _already_ light-years ahead of Windows Mobile. Second, from what I've seen of the SDKs, Google is doing quite a bit (most notably with their manifests) to maximize the reach of the platform (e.g. netbooks, automotive systems, set-top boxes) without unduly burdening cross- device portability. ------ zyb09 well it kinda looks ugly... ~~~ rbanffy What's about that golden thing in the center of the cursor pad? ~~~ 8plot I believe it's the fingerprint scanner. ~~~ rbanffy I imagined a blood-sampler for foolproof biometric authentication.

Giving Away Our Recommendation Engine - kky http://blog.mortardata.com/post/82195614895/giving-away-our-recommendation-engine-for-free ====== mck- Fwiw, here are two light-weight feature-based recommendation engines I built for Node.js (for situations where you have the cold-start problem and therefore can't rely on user/item based collaborative filtering): Alike [1] and Look-Alike [2] [1] [https://github.com/axiomzen/Alike](https://github.com/axiomzen/Alike) [2] [https://github.com/axiomzen/Look-Alike](https://github.com/axiomzen/Look- Alike) ~~~ yblu Thanks for sharing. What do you mean by the "cold-start" problem? Just want to know exactly when I can use your engines. ~~~ elwell Just speculating: not having a recommendation when you first begin because you don't have any data. ~~~ mck- Exactly right. I borrowed that term from Chapter 2 on Collective Intelligence [1] [1] [http://shop.oreilly.com/product/9780596529321.do](http://shop.oreilly.com/product/9780596529321.do) ------ contingencies So hang on, what exactly is a recommendation engine? They give examples of LinkedIn ( _people you may know_ ) and Amazon (presumably _other people who bought this_ , _so-and-so 's list of such-a- subject books_). That makes sense, though the segment of businesses that may actually benefit seems limited. Social stuff, sure. Most of us? What's the minimum recommendable-entity/category-or-user threshold that this makes sense for? Is success with these sorts of engines merely a reflector of poor UI design in your normal UX? (Of the above examples, the first seems very unidimensional - in that it's basically a simple graph distance - and the latter also rather rudimentary and often irrelevant). So what exactly is this thing providing? Graph analysis? I think not. It reads more like some kind of raw timestamped user behavioural event data processing to infer relationships between users or products they interact with. Reading through the docs it seems this is a layer on top of Apache Pig ([https://pig.apache.org/](https://pig.apache.org/)) - _a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs_. I think clarity in explaining this thing could be improved, particularly selling clearly what a recommendation is and when its useful. Using phrases like "award winning" doesn't help. PS. Why all the downvotes? Sheesh. ~~~ icambron I suspect you're being downvoted for having a dismissive tone in the same breath as you admit to not understanding the problem space. My guess is that the marketing copy on the site isn't targeted towards you, so it shouldn't surprise you that you don't understand it, whereas their target customers know all sorts of things about, say, Pig. That's fine, but then your comment should read like, "Can someone explain to me what this is for?" Instead, your comment is dripping with condescending snark, lecturing someone or another about how this thing you don't understand probably isn't useful, and incredulous that you don't understand something on the internet. Imagine opening an advanced textbook on a subject you don't understand, reading two paragraphs of it, and throwing up your hands in disgust because _what does this even mean?_ ~~~ contingencies Apologies, condescending snark was not the intent (I can't even see where you see that, actually!). In response to your more salient points, it could be argued that a web+EC2 layer on top of existing software is hardly an _advanced textbook_. Likewise, their announcement's stated intent is to gain customers, so feedback on what's unclear should be well within an acceptable scope of discussion. Finally, I doubt any of us are excluded from their intended market as software people move frequently between problem domains. ~~~ erichmond For the record, this reply seems as snarky and dismissive as the first. Hopefully some constructive criticism. ~~~ contingencies Thanks. ------ olidb2 FWIW we've been using the mortar platform to run large pig jobs without a fuss at [http://datadog.com](http://datadog.com) and we've been very happy with it. Glad to see them contribute their recommender code too. ~~~ alecsmart1 Can you please suggest why you need a recommendation engine for datadog? ~~~ olidb2 We don't use the recommendation engine but the underlying platform, which makes it really simple to write and run pig jobs. Though the majority of our business deals with real-time data processing, the ability to crunch numbers in batch without dev or ops overhead is attractive and well worth the price to us. ~~~ kldavenport Is this better or similar to Hue? ------ pixelmade I'm curious what the business case was for open sourcing the code. Maybe to create an ecosystem? ~~~ showerst From the "What you'll need" section of the first tutorial - A Mortar account. You can sign up for a free Public account with Mortar here. If you want to keep your customized recommendation engine code private, you will need a Solo-level account ($99/month). Beyond that, you'll only pay for your actual usage of AWS cloud services (we never add an upcharge). Kudos for the open source, but it looks like to actually use this for business you'll still need to pay. Unless i'm misreading it, "Open source but you'll still have to go through our platform" is pretty disingenuous. ~~~ ethanbond It reads like "open source but not free to make proprietary." First, it's awesome just to see source as something to learn from. Second, it seems reasonable they don't want people forking, modifying then profiting from their work without contributing back to it - either by also releasing source or by paying. I think it's a nice model actually. ~~~ catern It's called the GPL. If that's really the model they're trying to create, it would be nice if they just used the GPL. ------ dsheth Anyone know of any comparisons between this and Apache Mahout? I've used Mahout's Item-Item recommender in the past, and it's worked well, just wondering if there were advantages to this recommender. ------ ASquare I'm sure plenty of good karma (even the non-HN kind) is headed your way - kudos. ------ X4 WOW, Awesome Documentation and Product!! Kudos and Greetings from Germany 😊 Those who know what Hadoop, Pig and the whole "Data Science Stack" is, will find this surely useful.

Mexican Drug Gangs Kidnap Computer Hackers and Programmers - voodoochilo http://resources.infosecinstitute.com/mexican-cartels-infosec/ ====== dannyobrien There's nothing in this article to confirm that headline, apart from the sentence "Recent claims that computer programmers are being forcibly recruited by Mexican drug gangs, if true, suggest that these groups are acquiring the ability to reap the potential profits of cyber-crime", which has no citation. I'd be very interested to hear of corroborated incidences of such kidnapping or recruitment occurring. I was in Sinaloa, Mexico this month actively looking for such evidence as part of my work. There's some indication that the cartel have reasonable IT infrastructure (which isn't surprising, given their size), and some growing involvement in physical piracy (counterfeit items in markets have to be marked with a cartel symbol, which is purchasable). But I've yet to see strong evidence that they are involved in "cybercrime" in any organized fashion. They certainly take discussion forum flamewars pretty seriously though: [http://www.cpj.org/internet/2012/03/online-news-sites-as- bat...](http://www.cpj.org/internet/2012/03/online-news-sites-as-battleground- for-mexican-drug.php) ~~~ sebastianavina From what I understand, drug cartels need software for running their bussiness, and because they can't take a call to SAP and have a representative build a custom solution, they just kidnap programmers, extortion them and make them build the software they need for bookeping and all the stuff made by computers on this days. ~~~ adambyrtek This doesn't seem very convincing. Simply paying programmers lots of money would be a simpler and more effective solution. They could certainly afford that, and bookkeeping is too critical to their business to risk. Would you suggest that they kidnap lawyers and doctors as well? ~~~ sebastianavina Well, they don't kidnap them... They just hire them, and when they want to quit or resign the job, they just can't. ------ hef19898 Sounds too much like Password: Swordfish 2.0 to me. Unfortunately I can't access the article right now. For me, one thin gis sure, the cartels aren't stupid. At least the leaders and the heads, that is. Don't judge the organization by the goons welding guns and that get killed. They are running a multi-billion dollar business, and I'm pretty sure that they know that forced labour only gets you so far in anything more important than packaging (even thats not sure, given the budget they have and mexican salaries). So I think they are rather hiring the best IT-guys they can get along with the best intel-guys they can get. These hackers may not be of the "don't be evil"-type, what after the cartels aren't in that kind of business neither. ~~~ hef19898 I'm quite new to HN, so I have a question. Was anything wrong on my comment that I'm the only one to get down voted on this topic? I'm not going to bitch around due to that, don't get me wrong, I only want to understand why, tht's all. :-) ~~~ dagw Random downvotes are a fact of life on HN, if for no other reason than the close proximity of the vote buttons (I know I've accidentally down-voted more than a couple of stories over the years). These things tend to correct themselves if you're patient and wait a few hours. ~~~ hef19898 Ah, that could be a reason. Again, no offense taken, I just wondered. There is no other thing like randomness to add some salt to life! ------ malandrew Were I an activist involved with this, I think that providing a "dead man's switch as a service" could be quite useful. Were I to engage in risky journalism, while living in close proximity to these gang wars, I'd want a way to spill additional information to the media were I to go missing. ~~~ there <http://www.deadmansswitch.net/> ------ brianbreslin I was told by some Mexicans that the cartel is already employing (as in paying salaries to) numerous hackers and IT professionals. They have very high level of banking access and technology that rivals government spy agencies. Unlimited funds will do that for you though. ~~~ coopdog Kidnap is funny though, they could kidnap someone and say comply with everything we tell you. If either you or your family leave our control (they could be in separate places) or signal for help we will kill you both. The only escape would be to perfectly synchronize it. Would work especially well if two or more kidnapped hackers were forced to monitor each other, adding a prisoner's dilemma to the mix. If one failed to catch the other's escape he/she and their family would be killed. So it isn't impossible to enslave security professionals. ~~~ unimpressive >Would work especially well if two or more kidnapped hackers were forced to monitor each other, adding a prisoner's dilemma to the mix. If one failed to catch the other's escape he/she and their family would be killed. And you just described what would be an _amazing_ cyberpunk novel. Two security professionals both try to escape and prevent the other from escaping at the same time. If done right it could quickly become the best kind of thriller; the one where you're actually speculating as to what happens next. ------ alecdibble The section on the feud between Anonymous and Los Zetas was fascinating. It's very interesting that Anonymous has that kind of leverage against such seemingly powerful people. ~~~ FreakLegion No part of that story has _ever_ been corroborated. Barrett Brown isn't exactly a trustworthy source. ------ kingpharoah HN readers around the world should be able to do something to take heat off the Mexican people. ------ ernirulez This is a very good opportunity for governments to make public opinion even worse against hackers and therefore make new laws to control us even more. That will be very easy for them: Hackers -> Help drug gangs -> Hackers = Criminals ------ user2459 Events like this are the main reason why The War on Drugs™ is so dangerous for everybody. It's not the drugs or gangs killing gangs. It's the gangsters that live through it sitting on piles of money who now have the resources to expand into crimes that take more than a gun, friends with guns, and some luck. Because of the prohibition they can now hire hackers to commit crimes for them in any place in the world. It's going to get harder to implicate them in crimes, and yet easier for them to make money off them. Possibly the worst part is that this happened to us(and is still affecting us) in almost exact detail during the prohibition of the 20s and yet we continue to shrug our shoulders and keep giving them more money. ~~~ gregbair Well, first of all, this article is complete BS with no corroboration or even references. Secondly, even if there weren't a war on drugs, the gangsters would find something else to peddle, like people. Gangsters existed before prohibition and existed after, they just moved into different rackets. ~~~ oinksoft Oh, come on. Joe Blow wants to buy weed, blow, crank, and dope because his life sucks, he's bored, or he just likes the stuff. Very few people like that are in the market for a human being. You really can't compare the profitability of an easily produced and smuggled commodity with something like the trafficking of persons. ~~~ gregbair I'm not, I was simply saying that if all those things were legal, criminals (the cartels, not the users) would find something else illegal to peddle. These people look for an easy buck, and right now, that happens to be in illicit drugs. Take that profit away, and they'll just find something else. ~~~ mjallday But some easy bucks are easier and less damaging than others. No doubt if drugs are legalized they will move on to something else but the total market they can address will be smaller. ~~~ DanBC People trafficking is the second largest organised criminal activity. It's low risk with bigger profit margins than drugs. Data is hard to get, partly because there's little international agreement about what should be measured as well as the difficulty of finding the victims. Here's a UN document which is reasonably cautious. (<http://www.ungift.org/docs/ungift/pdf/knowledge/ebook.pdf>) Global profits are > $30billion USD. > _the total market they can address will be smaller._ Bigger profits. ------ shareme What is sad is that US citizens do not understand that this un-civil war has been going on for the past 30 years and we as US citizens have done nothing that has a statistical impact of reversing the damage. Instead we invade Iraq and Afghanistan based on the political connections of a former Haliburton employee and stockholder. And if we do not wake up soon.. WWII will be on our doorstep. ~~~ armandososa I've thought about it too. You guys catch Saddam and Osama, why can't you launch some drones and put a missile trough capo's asses? I guess our lives and peace are not worth the intervention. ~~~ dagw Can you imagine the magnitude of the political shit storm on both sides of the border the first time a US drone operating in Mexican airspace with the blessing of the Mexican government blows up a few Mexican kids? ~~~ yummyfajitas And unlike Afghanistan or Iraq, Mexico actually matters to the US. They are our #3 trading partner (Canada and China are #1 and #2), even ignoring trade in labor (and trade in drugs). Messing that up would be foolish. ------ trotsky bullshit

Ask HN: Getting Eyeballs - kyro Seems like Arrington's post has sparked some conversation about the community and founders' desperation for exposure. What's the problem? Are people not clever enough to come up with unique marketing plans? Or do most of them fail?<p>Coming from someone who hasn't been involved in a startup (yet!), I've never really understood this inability among founders to develop clever marketing campaigns. Everyone seems to think they need to score a blog post. And even if that's what it takes, there's huge frustration and difficulty with doing so.<p>During Startup School '08, Arrington said the best way to get on TC was to create a story. That seems pretty straightforward to me. So create one. That doesn't mean email him asking him to demo your product. It means to stir up some drama. Leak a screenshot, 'accidentally' post something on twitter, etc. I'm pretty sure that's the type of story he's talking about. In being creative with creating features, you also need to be master storytellers.<p>Instead of blog posts, there are myriad of things you could do for promotion and eyeballs. Make a bogus/cute little app that might not relate to your site like that 'Is Hillary Swank Hot?' app that was here a week ago. Make it a gag site and promote there. Here's an idea: Make weekly videos of a puppet version of your logo gruesomely killing the logos of your competitors or just popular sites in general. Be a sensationalist.<p>It really shouldn't be all that hard, guys, honestly.

You can't forget that "crowdsourcing" is in. ------ jamesbritt "Make a bogus/cute little app that might not relate to your site like that 'Is Hillary Swank Hot?' app that was here a week ago." Except that gave me a poor impression of the people behind it, since the notion of it being an "app" struck me as disingenuous.

The Disaster of Python 3 - pcr910303 https://changelog.complete.org/archives/10053-the-incredible-disaster-of-python-3 ====== nas I suggest taking this article with a grain of salt. The assumption seems to be that it's totally fine that Linux can have filenames that are arbitrary byte strings and that don't convert to valid Unicode text. First, Python 3 has a good way to deal with those. See PEP 383: Non-decodable Bytes in System Character Interfaces. Second, having filenames that are not valid Unicode text (even if Python 3 has a way of handling them and round-tripping them) is going to cause you a lot of pain. No one who has thought through all the issues thinks its a good idea. The modern computing world uses Unicode text all over the place. Filenames are manipulated by humans and we deal with them as text. The idea that 8-bit byte strings are the ideal way to deal with text is a dead end. I expect we are going to see more of these kinds of articles now that Python 2's EOL is coming. In retrospect, you could argue that Python 3 should store Unicode text in memory has UTF-8. However, at the times decisions were made, UTF-8 was not dominate as it is now. ~~~ rini17 So just handwave it and it eventually goes away? Nope, as long as: 1\. Python standard library itself does not adhere to PEP 383. (Which is not likely to be fixed if everyone has such dismissive attitude.) and 2\. Operating systems do not enforce valid UTF-8 on filenames. (This is unlikely to change sooner than in few decades, if at all.) ~~~ matheusmoreira > Operating systems do not enforce valid UTF-8 on filenames. Should they? There is no difference from a file system perspective. We'd still run into problems even if they did: the line feed is a valid UTF-8 character and is one of the characters with special meaning in many programs. Dealing with file names properly is a chore even on bash. [https://mywiki.wooledge.org/BashPitfalls](https://mywiki.wooledge.org/BashPitfalls) ~~~ skissane > We'd still run into problems even if they did: the line feed is a valid > UTF-8 character and is one of the characters with special meaning in many > programs. They could ban new line from file names too. See this proposal: [http://austingroupbugs.net/view.php?id=251](http://austingroupbugs.net/view.php?id=251) ------ hprotagonist As always, the one true link is this: [https://nedbatchelder.com/text/unipain.html](https://nedbatchelder.com/text/unipain.html) Read, understand, and be glad that the interpreter isn't trying to "help" any more! ~~~ pen2l I just want to chime in and say that Ned Batchelder is one of the greatest human beings alive. Or, at least, to me he is. This man helps so many people with nothing in return. He's a regular on some python IRC channels, he has personally helped me so much. He makes difficult concepts easy to understand. I encourage everyone to watch his pycon talks. Start with his talk on loops: [https://www.youtube.com/watch?v=EnSu9hHGq5o](https://www.youtube.com/watch?v=EnSu9hHGq5o) ~~~ stevenjohns There's a few outstanding people that make me love the Python ecosystem, Nedbat is definitely in that list. FunkyBob (Curtis Maloney) is also a staple with Django, he's spent years and years helping people and asking for nothing in return. ~~~ commandersaki I'll throw in Raymond Hettinger & Jack Diederich -- excellent peeps. ------ oefrha Okay, another flamebait article. I'll byte, uh no, bite. > Inconsistencies in Types There's just no such thing as a builtin character type in Python. No, that's not new to Python 3. '/' is a str. b'/' is a bytes. Indexing str gives you a str because there's no such thing as a character type, and introducing it would be pointless. Indexing bytes gives you a byte (an int) instead of a bytes because if you're working with a raw byte sequence you probably want to access the bytes individually? If this wasn't the case people working with raw byte sequences would probably be even more displeased during the transition period. "But I can't port the code by prepending b to every string literal!" Sorry, that's not the correct way to port. > Bugs in the standard library Yeah, that might be Unicode-related bugs in PSL. They were users' problems in Python 2 era, now Python core team shoulders the burden. Instead of every single programmer making Unicode errors in their own code, if you find an error in PSL you can fix it once and for all. ------ StefanKarpinski This problem in Python 3 is not limited to OS file names, that’s just one way to get invalid Unicode data. But invalid data happens all the time when working with real data. The Python 3 string design requires that all strings must be valid Unicode or Python will raise an error. This is a really unfortunate property that has bitten every single data scientist I know who uses Python 3. At some point, often hours or days into a long, expensive computation, one of their programs has suddenly encountered just a single invalid byte and crashed, costing them days of time and work. The only recourse for writing robust programs that can gracefully and correctly handle invalid data is not to use strings, which, frankly makes the string type seem pretty useless. The Python 3 string design also necessitates scanning and often transcoding every piece of string data that it encounters, both on the way in and again on the way out. That means that not only is the string type inappropriate for any data that might not be valid Unicode, it is also inappropriate for any data that might be large. I’ve been meaning to write a blog post about how Julia handles strings, but haven’t yet gotten around to it. Among other benefits: \- You can process any data as strings and characters, whether it’s valid Unicode or not. \- If you read any data as strings or characters and write it back out, you get the exact same data back, no matter what it is, valid or not. \- Invalid characters are parsed according to the Unicode 10 spec. \- You only get an error if you actually ask for the code point of an invalid character, which is a fairly rare operation and must error since there is no correct answer. \- The standard library generally handles invalid Unicode gracefully. \- You can use strings for large data: there’s no need to look at, let alone transcode string data—if you don’t need to access something no work is required. ------ Areading314 It's open source. If you are having so much trouble with your ultra niche filename use case, just open a pr and clean up some of the code. ------ xpasky This is a nostalgic article, as underlined in the closing section about XON/XOFF and mainframe-compatible escape sequences. The world is moving on, and while historic systems are beautiful (I still have a 2.11 BSD emulator running - or rather runnable - somewhere), at some point you need to weight the breakage for legacy users against the cost of maintenance of the compatibility. Indeed, POSIX is still mandating that filenames are arbitrary byte sequences. But it is just becoming impractical, and in the end it's up to whoever has the motivation to have it working to keep it working, and if there's not enough people with this motivation it's just going to inevitably rot. It's likely that 10 years from now, anything non-Unicode will be completely broken on modern (desktop, at least) systems and perhaps Linux even gets an opt-in mount option for enforcing filenames to be utf-8-compatible (which may change to opt-out another 10 years on, just as POSIX is going to evolve too in this regard). Yes, it's a pity and I likely still have some ISO-8859-2 files from 1999 on my filesystem. But I think it's unreasonable for anyone to waste time with that support. And I wouldn't advise anyone wasting extra 20 hours of your developer life on building things around ncurses instead of a more direct approach - build a cool feature in that time instead! ------ mixmastamyk Not a disaster, been loving it at least five years. Still, a few niche bugs could be fixed, why not? In the meantime as a workaround, make fs links with ascii names and/or subclass ZipFile. I had to monkey patch a Py2 stdlib module once to fix it for a year or so until it was fixed. Probably httplib if memory serves. ------ rcarmo I just don’t see the problem here - most of the piece completely ignores documented ways to deal with encodings. For instance, I export PYTHONIOENCODING=UTF_8:replace in some machines where I know the default locale and terminal settings might cause problems with logging. Edit: premature posting from mobile ------ 3JPLW The site seems to be having some trouble keeping up; here's an archive/cache/mirror: [https://archive.is/efTT9](https://archive.is/efTT9) ------ mantap The string encoding is actually the best part of python 3. There's a large number of small feature regressions that really irritate me, like the removal of comparators, and gratuitous changes like the removal of print statements and moving shit around without providing aliases. But the bytes/str distinction is actually really useful for anybody who uses unicode, which is everybody. If Python 3 had just made that change and no other breaking changes, the transition would have been much faster and the value propositon much clearer. ------ drivingmenuts I’m fascinated by the idea that someone is using an IBM 3151 terminal in 2019. Other than for nostalgia, should not those have been retired about a decade ago? ~~~ jgoerzen I bought it off eBay a few weeks ago. As to why - sitting in front of emacs with a clicky model M keyboard produces a very different frame of mind. I am more focused and more deliberate in what I type (one doesn't just type ls /usr/bin on such a thing). Although it's by no means my primary computing device, I do find myself going down there for at least a little while on most days. It is a pleasant break, a change of scenery, a different mental state. I got it, and my vt420 and vt510, after thinking about the bifurcated nature of computing history. Although I started with computers in the 80s, it was the PC side of things. The Unix/"big iron" simply wasn't accessible to many in those days. I have spent decades doing work day in, day out in what amounts to a fancy vt510 emulator (xterm). I wanted to use the real thing. Also it got my son to play zork with me. I wrote about it here: [https://changelog.complete.org/archives/10013-connecting- a-p...](https://changelog.complete.org/archives/10013-connecting-a-physical- dec-vt420-to-linux) and here: [https://changelog.complete.org/archives/10031-resurrecting-a...](https://changelog.complete.org/archives/10031-resurrecting- ancient-operating-systems-on-debian-raspberry-pi-and-docker) ------ fargle Normally when I see a headline of this sort, I expect I will find another over-enthusiastic bombastic smoke-and-mirrors hit-piece. The fact that this article hits home and is right scares me a tiny bit. For example: "I should note that a simple open(b"foo\x7f.txt", "w") works. The lowest-level calls are smart enough to handle this, but the ecosystem built atop them is uneven at best." Oh Crap... ------ enriquto i do not understand why the unicode type is needed inside the program. Why can't you treat everything as bytes? It's not like you can't concatenate two strings of bytes! If these bytes mean something or something else, this is a concern for the user of the program that feeds it these bytes. The program itself could be oblivious to that. ------ sytelus Title is overblown. At best this might be "disaster" for string/bytes types but many would argue even that is not the case. ------ pontifier This one (Python 3) does not spark joy. Somehow python, as a whole, started to feel like it needed too much boilerplate and special fiddling to do simple things. I felt like I spent way too much time keeping track of different environments or versions to make each project work, and was always dissatisfied. ------ bildung Authors problem starts right at the beginning: He mentions that POSIX filenames consist of 8bit _bytes_ , but then uses a utf-8 _string_ as the example filename in the first code block. ------ sprash Python 3 is a disaster for many other reasons, UTF-8 bugs is just one of them. So far I'm sticking with Tauthon[1] which seems to be the best of both worlds. 1.: [https://github.com/naftaliharris/tauthon](https://github.com/naftaliharris/tauthon) ~~~ nas I don't wish the Tauthon project ill but I suspect people are underestimating how much work goes into maintaining Python 3. If the Tauthon project scope was limited to taking Python 2.7.X and doing bug fix only releases of it, I think it could be a successful project. Since they seem to be backporting features from the 3.X branch, I don't see them keeping up. Python 3 has too many users at this point. If you look at the Tauthon commit log, it seems clear they are being left behind. There is another problem with trying to backport selected Python 3 features. How do you decide what gets backported? New features will introduce incompatibility. Even if the feature is forward compatible, you end up with code that will run on Tauthon 2.X but not on Tauthon 2.X-1. If it just a better Python 2, that's fine. When it is some 3rd kind of thing with a relatively tiny user base, who is going to use it? ~~~ sprash > I suspect people are underestimating how much work goes into maintaining > Python 3. And I suspect people are vastly overestimating it. The latest additions to Python look like they were made by a committee. It is the committee style work that eats up all the man hours. The programming itself is rather simple. > Python 3 has too many users at this point. Most were dragged along by force. Many people are happy that 2.x versions like Tauthon are still maintained. To all projects I'm personally involved in (mainly scientific) python 3 offers literally ZERO advantages and only causes additional costs. > I don't see them keeping up. > How do you decide what gets backported? New > features will introduce incompatibility. You gave your own answer. All features that don't introduce incompatibility are going to be backported. In that regard "keeping up" is also not the top priority. ~~~ joshuamorton Py3 is currently more performant than py2. There are a number of py3 only features pushed for by the scientific community (@ is the most obvious, but there are others). ~~~ sprash > Py3 is currently more performant than py2. No it's not. It is a clear regression. The minuscule performance improvements stem from the enforcement of xrange() vs range(). But using xrange() on 2.x is still faster. ~~~ joshuamorton No, starting in 3.6 or 3.7, there are general performance improvements at the c level in the interpreter.

Tell HN: Digital Ocean will start collecting fees for backups - jrs235 DO subscribers have received the following email:<p>Some Important News About Backups<p>Hi there,<p>We’re in the process of updating our backup system and we wanted to give you a heads up about some changes you’ll be seeing.<p>You may have noticed that, though the cost for backups has always been 20% of your Droplet usage, you’ve never actually been charged. Don’t worry, we’re not coming to collect for past backups now. So far, we’ve been happy to offer backups, free of charge.<p>Starting in February, however, you will begin to see charges for backups on your monthly invoice. Backups will now happen on a weekly basis, with at least four backups occurring per month. You&#x27;ll only be charged for a maximum of four backups in any given month and you&#x27;ll never be charged for backups that fail to happen. Payment for backups occurring in February will be due on March 1st, and so forth.<p>We&#x27;ll provide you with a scheduled window each week in which your backup will occur. This information will always be available in both the control panel and the API. If you’d like a more in-depth explanation of how backups work – and when and why to use them – we’ve prepared some detailed articles on the topic: Understanding DigitalOcean Droplet Backups DigitalOcean Backups and Snapshots Explained How to Choose an Effective Backup Strategy for Your VPS<p>Happy Coding,<p>Team DigitalOcean<p>UPDATE: Made paragraphs to remove wall of text. ====== squiguy7 Correct me if I am wrong, but if you enable this option when you make a droplet a popup comes up and tells you it will cost 20% of the droplet's fees per month. This isn't news to me as I don't use it because I have such a small amount that I pull it down to my own machine. ~~~ jrs235 You are not wrong. What is newsworthy is that they are going to begin actually collecting that 20% which they have not been actually charging for in the past. This is more of a heads up for those that see an increase in their monthly bill/charge. ------ rpietro agree this is nuts. EC2 always an option ~~~ stephenboyd It's an option for people who want the convenience. DO has free snapshots and you can roll your own backup system anyway. ------ novocraig 20% for four backups per month? That's insane. ~~~ Someone1234 It is opt in in fairness. You have to set it to backup when you create the droplet. 20% flat is not THAT crazy, backup services and EC2 and Azure both nickel and dime a bit via bandwidth and storage fees. ~~~ toomuchtodo To snapshot EBS volumes in EC2 is pennies per GB. 20% flat is crazy. ~~~ jrs235 Its really not though, as long as you are using the smaller droplets. $5/month 20 GB droplet would be 80 GB of backups for $1.25 on AWS S3 that would cost $2.40 $10/month 30 GB droplet would be 120 GB of backups for $2.50 on AWS S3 that would cost $3.60 $20/month 40 GB droplet would be 160 GB of backups for $5.00 on AWS S3 that would cost $4.80 $40/month 60 GB droplet would be 240 GB of backups for $10.00 on AWS S3 that would cost $7.20 $80/month 80 GB droplet would be 320 GB of backups for $20.00 on AWS S3 that would cost $9.6 ADD: Then if you compare outgoing to internet bandwidth costs DO is better. Assume you use all 1 TB of your small droplets bandwidth. That's included in your $5 while on AWS that will cost you an extra $89.91. UPDATE: Bandwidth pricing for droplets is for incoming and outgoing, so assuming 50/50 (bad assumption) then AWS would cost you $44.91 more per month.

One device, 1TB of personal cloud storage - blaze33 https://www.spacemonkey.com/ ====== tckr I was one of the kickstarter backers and I am quite disappointed in the product … so far as I have dismembered the SpaceMonkey and the 2TB hard drive now is part of my Synology NAS setup. SpaceMonkey's features are at best rudimentary and only usable as a personal cloud storage. Don't even think about working in a team (to be fair, the team is working on sharing features). The device used huge amount of bandwidth and made the network in my coworking space unusable. So today I can only recommend to look into a different solution … ~~~ antr I too was a backer in their Kickstarter campaign. Due to the poor communication, continuous delays, and uncertainty on pricing and ownership, I requested a refund. I then bought a synology NAS, setup it up with raid 10, vpn, and Amazon glacier backup. I couldn't be more happy with the decision. Since then, SpaceMonkey got acquired... which I find fascinating. ~~~ tw04 Skip the glacier and use crashplan for backup. Cheaper, and better options for restoring your data (like having a drive mailed to your house vs. pulling it over the WAN). ~~~ jm4 Unfortunately, Crashplan doesn't work on a Synology box. Even if you are willing to muck around in Busybox it still won't work because there is no inotify support. The best you can do is sync your Synology to a PC and then upload to Crashplan from there. Support for S3 and Glacier is built in and very easy to configure. It's not a major issue if you have a RAID setup because it's less likely you will have to restore from backup. I've only had single drives go bad and I hotswapped them. I would feel much differently if I had a single drive unit. ~~~ driverdan That's untrue. Synology devices have supported CrashPlan for a while. DSM 4: [http://www.hanselman.com/blog/HowToSetUpCrashPlanCloudBackup...](http://www.hanselman.com/blog/HowToSetUpCrashPlanCloudBackupHeadlessOnASynologyNASBackupStrategies.aspx) DSM 5: [http://www.hanselman.com/blog/UPDATED2014HowToSetupCrashPlan...](http://www.hanselman.com/blog/UPDATED2014HowToSetupCrashPlanCloudBackupOnASynologyNASRunningDSM50.aspx) ~~~ junto To be fair, this isn't a Synology package, it is provided by one guy who works hard to try and get the Java Crashplan code to work on Synology. When Synology upgrades the DSM it stops working. Check out the forums to see the pain points people have to address to keep this headless client working: [https://www.google.com/search?q=synology+crashplan+not+Worki...](https://www.google.com/search?q=synology+crashplan+not+Working) It is a hack. There should be an official release from Crashplan or Synology. Same for the other big backup cloud providers. If there was something better and supported on Synology than Amazon S3 or Glacier, I'd personally be prepared to get my wallet out. These companies are missing a big market of Synology owners who are desperate for an alternative, and no I don't want to use HiDrive. ------ unwind So, if it's "Only $49/year" (top of page) but also provides "1TB of personal cloud storage for $10/month" (bottom of page), how many months are there in their years? Do I pay per year, or per month? Is the hardware "free"? Very confusing, and that took _maybe_ 20 seconds to find. ~~~ alenlpeacock The confusion results from two different plans: Plan A: buy the device upfront and own it. Price includes 1 year of network backup service. After the first year, if you want to continue the network backup, it's $49/year ($4/month). Plan B: don't pay anything upfront for the device and lease it plus the service for $10/month for as long as you like. Plan A is the only service available directly from the website currently, and we need to clarify the copy on the webpage -- thanks for pointing out to confusion. ~~~ gregd As a Kickstarter backer too, we've pointed out to you guys for _months_ that your pricing scheme was confusing and didn't make any sense. You haven't cleared it up any since. ------ mrb I have been watching Space Monkey for a while... I love the concept of local- to-your-home-network storage made easy to use and easy to share anywhere, even on devices outside your home network. This easily beats any cloud service when it comes to synchronizing speed because I can sync at 1 Gbit/s on my GbE network, vs. the ~10 Mbit/s uplink of my cable Internet. There is also Pogoplug [1] which is a superior idea IMHO: the user provides his own USB hard drive(s). This reduces the price of the device and gives more space flexibility: you can connect any size and any number(!) of drives via a USB hub. There is another company doing something similar to Pogoplug, but I cannot remember their name at the moment. Of course the downside of Pogoplug is that there is no backup. But for my own needs, I would prefer Pogoplug's trade-off (unlimited storage & no backup & no constant Internet traffic) compared to Space Monkey (1TB limit & automatic backup & constant ~400kbit/s of traffic background to the SpaceMonkey distributed network). [1] [http://www.theverge.com/2012/4/5/2910802/pogoplug- series-4-r...](http://www.theverge.com/2012/4/5/2910802/pogoplug- series-4-review) (I link to a review because the company's main website does not do a good job of describing the product: [http://pogoplug.com/devices](http://pogoplug.com/devices)) ------ blaze33 Seeing the discussion around disk42 (Saas version of seafile) [https://news.ycombinator.com/item?id=8739094](https://news.ycombinator.com/item?id=8739094) I thought it would be a good time to repost the space monkey link (not that I'm affiliated nor a user) to see where we are in terms of distributed storage protocols now. Some q&a I had with their co-founder: [https://news.ycombinator.com/item?id=6996053](https://news.ycombinator.com/item?id=6996053) (parent discussion mostly about an alleged kickstarter scam) ~~~ notum Actually Space Monkey was discussed before as well: [https://news.ycombinator.com/item?id=5564546](https://news.ycombinator.com/item?id=5564546) While the fragmented/distributed backup approach is cool and useful some people might not like paying $50 for the privilege of seeding other people's files with their bandwidth. ~~~ blaze33 Thanks, I hadn't seen this thread before, I was actually thinking that an open protocol would allow you to have a fast/reliable/etc. backup in exchange of a share of your local storage. Obviously if it's phrased like I'm paying to have other people use my bandwidth, that's a big issue. ~~~ ansible A few years ago, when Dropbox was starting to get popular, I was thinking of a similar scheme. You would pay for the device, and then you would get X% free cloud storage as long as it was online. Some people would prefer a fixed up front cost and no monthly fee. ------ cabirum "So, what a wireless speaker has to do with cloud storage?" — my first thought after opening the website. "Oh, its not wireless" "And not a speaker." ------ zhte415 So, the storage and distribution model is a bit like FreeNet, distributed across other devices, but everything is private, no sharing? ~~~ alenlpeacock Everything is private, every user has a unique key associated with their account, and every object (file and folder) has unique, individual encryption keys generated for it. Because of the way data is encrypted, the system supports sharing at the file and folder level without granting access to other data in a user's filesystem. ------ akerl_ I admit to being confused by their security statements. Is the OS and code running on the device open sourced? Given that it looks like the device is handling the encryption, and I got the device from them, I don't see any publicized way for me to verify that any encryption is actually happening. ------ RyanMcGreal > Whether you use an iPhone, Android, Mac, or Windows, we have you covered. Does it support Linux? ~~~ cefstat The page [https://www.spacemonkey.com/tour](https://www.spacemonkey.com/tour) mentions under Linux "Alpha access by request". ------ thedangler I want to try this one. [https://www.lacie.com/ca/products/product.htm?id=10597](https://www.lacie.com/ca/products/product.htm?id=10597) ~~~ alenlpeacock One of the reasons Space Monkey exists: [http://www.infoworld.com/article/2856553/cloud- storage/you-c...](http://www.infoworld.com/article/2856553/cloud-storage/you- cant-buy-a-cloud-at-best-buy.html) ------ kolev People continue to abuse the term "cloud" these days... ------ rehemiau [http://sherlybox.com/](http://sherlybox.com/) I'd say sherlybox is a better deal ~~~ serf [http://pogoplug.com/devices#pick](http://pogoplug.com/devices#pick) a top end pogo plug with a 3TB drive would be cheaper and more capable (usb3.0/sd card/user choice in HDD), or you can save fifty bucks if you don't need multi-user support.

Reddit CEO admits he secretly edited comments from Donald Trump supporters - idleist https://techcrunch.com/2016/11/23/reddit-huffman-trump/ ====== Natsu Related discussion can be found here: [https://news.ycombinator.com/item?id=13027031](https://news.ycombinator.com/item?id=13027031) ------ defgeneric This could cause a meltdown that will make previous reddit meltdowns look tame. Facebook higher-ups have been fired for creeping on ex-girlfriends. This is arguably worse--editing user's posts has huge legal repercussions. I would be pissed if I was a board member of reddit right now. A CEO is empowered and paid for exercising good judgment and leading people, not "trolling the trolls a bit" by violating the site's fundamental rules and creating a storm of bad press in doing so. ~~~ pulisse _editing user 's posts has huge legal repercussions_ Keep smoking that good stuff, SV. ------ redthrowaway It was a stupid decision, but it's not nefarious. He got pinged every time someone wrote "fuck /u/spez" in /r/the_donald, and he got sick of it. So he changed "/u/spez" to the members of the /r/the_donald mod team so they would get pinged instead. Professional? No. But not nefarious, either. ~~~ gormo2 I agree it was not nefarious, but it was a decision that shows unbelievably poor judgement, especially for a CEO. I'd be surprised if he keeps his position. He's undermined his fundamental role as the leader of one of the biggest social media sites by violating the trust that users put into the site's administration. The context as I understand it involves some ravenous hordes of conspiracy- theory redditors promulgating fake news stories and doxxing innocent people. However, by changing the text of these users comments, whatever their actions, and by admitting to it, Steve has opened the floodgates. Now there is no question -- in the minds of these users -- that the site is truly "against them" and willing to not only censor them but to rewrite history as they see it. They can no longer trust anything they read on the site. But what is worse is the effect and message this sends to normal users. How can, for instance, any person safely participate in an AMA now? When the real possibility exists to have their words changed out from under them, and no way to prove they aren't in fact the author? And from that, why would anyone post anything potentially personally identifiable, if (in their mind) some disgruntled admin could modify what they said to include false yet humiliating or criminal things (e.g., throw in racial epithets, link to porn, admit adultery / drug use) that might eventually link back to them. And how far does this go? Can admins send PMs under the name of other users? What else? To me at least, the scary thing is that Reddit posts that _only obliquely_ reference personal information have already been used as the basis for surveillance and legal action [1]... And taking one final step back, from a business side this drama goes beyond just being unprofessional. Reddit posts are now often linked to from news articles. How can the media trust the source they link to? If the content of posts are 'up for grabs' to be edited by admins in the minds of users and the media (even if they aren't in reality), then one of Reddit's functions that is growing in importance -- that is, news-making -- may be stymied. Harming trust is extremely dangerous for social platforms. And when it is the CEO themselves doing the harm, it could very well border on being suicidal for the site. [1] [https://np.reddit.com/r/AskReddit/comments/58hae4/what_is_a_...](https://np.reddit.com/r/AskReddit/comments/58hae4/what_is_a_piece_of_reddit_history_every_redditor/d90lago/) ~~~ _up I agree that this behavior is very bad and reddit lost a lot of trust. As I understand it pizzagate wasn't entirely fabricated "fake news". Instead it originated from strange code word ridden Podesta and Straftor Mails, that where published by wikileaks.

How the EVE Online Servers Deal with a 3,000 Person Battle - JGM564 http://penny-arcade.com/report/editorial-article/planning-for-war-how-the-eve-online-servers-deal-with-a-3000-person-battle ====== rauljara The report of the battle they link to (<http://www.pcgamer.com/2013/01/28/eve- online-battle-asakai/>) is even more fascinating to me. You spend hours and hours of effort in order to get a ship, and one way of thinking about them is as the time spent to earn them compressed into 3d form. Unlike (most) other MMO's, battles actually destroy things. So in that youtube clip, you're watching years and years of effort getting evaporated because of a mis-click. In most of the games I play, the pay off of the grinding is getting to enjoy fighting more. But I could never play EVE, because battles would be so anxiety provoking. There would be no pleasure at all in earning a Titan, because I would be forever terrified of losing it. Of course, all games are kind of there to destroy your time. But for some reason it doesn't feel quite as wasted when you have a virtual thing there that is bad-ass in proportion to your time investment. ~~~ fatbird That feeling of "My ship! My beautiful, beautiful ship!" is offset by the fact that major alliances tend to have strong reimbursement programs. If your dreadnought goes boom in a fleet op, you get the cost of another hull and gear, and get to draw on corp/alliance stores as well. Otherwise, they'd never get their supercap pilots out of the hanger :) ~~~ baddox What would be the point of having all this cool stuff if no one else even gets to see it and you don't get to use it? ~~~ fatbird If you spent six months grinding the ISK to buy and outfit a carrier, how willing would you be to take it into a battle where any of a hundred things could destroy it, including server lag or a random disconnection? ~~~ baddox I would invert the causality. Why would I spend six months outfitting a carrier if I had no intention of using it in combat or even flying it anywhere where other people would see it? ~~~ glesica Same reason people spend hours tending their farmville farms... ~~~ baddox I've never played Farmville, so I probably shouldn't speculate, but I'm under the impression that it is at least ostensibly a social game where you invite people to help with or at least view your farm. ~~~ glesica Yeah, but so is EVE and other games like it. I have never played EVE for any significant amount of time, but I did play WoW for awhile and there were tons of things that people would sink time into for purely social reasons. I imagine EVE is the same way. You don't just want a Titan because it is useful in the game, you want a Titan so you can have a Titan. ------ jere [Edit: this comment turned out not to really be about Eve and more about the difficulty of real time MMOs] This blows my mind. I've been thinking about writing a small multiplayer game for a few weeks. And today I was actually doing back of the napkin calculations. The thing that quickly became clear is bandwidth is O(n^2) where n is the number of players in the same location, since you have to share the location and velocity of each player with each other player. Here's an example of a calculation I was using. It's the monthly bandwidth in TB of having a certain amount of players in a shared space (3000 in this case), assuming that the location/orientation/velocity of each player's ship is contained in a measly 48 bytes and you attempt 30fps. (48 * 30 * 3000 * 3000 * 3600 * 24 * 30) / 1e12 = 33592 TB = 33 PB THIRTY THREE PETA BYTES to simulate a single battle for a month. I'm looking around at various VPS providers and the bandwidth they offer. Using the naive calculation above and the cheapest Linode offering and it'd take $3 million/month to support a single one of these ongoing battles. Now, I'm sure the numbers above aren't used in reality. Obviously, you can reduce the updates per second... but not by much. You can't shave much off how much you send. It at least gives you a sense of the orders of magnitude required to support such a thing. Even contemplating supporting 100-1000 people at once is looking very difficult for me to pull off. ~~~ gnarbarian I think one thing Eve has going for it (and this is only an assumption) is that it wouldn't need to sync each player's position on each frame. It could reduce the load dramatically by only sending the acceleration / orientation data for a ship. So if a ship has set a course and has stopped accelerating it doesn't need to send anything else unless that course is changed. ~~~ jere I haven't really played Eve, so I can't say. I'm imagining ships flying around and changing course constantly in a battle, but if someone can give a better description, I'd appreciate it. It'd be further reduced by several players sharing a ship... no idea how common that is. What I'm describing is definitely leaning more towards players that are constantly moving around though. It helps explain to me why in Asheron's Call, for instance, when you had too many people in the same city a "portal storm" arose and people started getting teleported out of the city randomly. ~~~ afterburner If you check the video you'll see it's very slow paced and the ships basically don't seem to move at all (maybe tiny unseen ones do I don't know) <http://www.pcgamer.com/2013/01/28/eve-online-battle-asakai/> ~~~ gknoy Part of the reason it is so slow is that (as mentioned in the article) the server slows time down (as far as 10% of normal) in order to ensure that nothing gets lost. ------ RickHull Fun facts: This fight was between the Honeybadger Coalition (HBC) and the Clusterfuck Coalition (CFC). The core of the Honeybadger Coalition is TEST Alliance, and the core of TEST Alliance is Dreddit, the "original" Reddit- based corp (there are / have been several, some of which predate Dreddit and have since folded). HBC routed the CFC, which has Goonswarm as its core, which is organized around the Something Awful forums. TEST Alliance was nurtured by the CFC for a long time, splitting off only in the past year to forge a more independent identity. As such, the hostilities between these old friends is hard to gauge. At this point, the presumption is that it's all in good fun. But that may change. ~~~ alex_c Admittedly I haven't followed Eve politics for over a year, but I would be very surprised to see Test and Goons get in a "real" fight (e.g. over sovereignty or revenue-generating moons). They both treat the game in the same way (a strange mix of competence, incompetence, and irreverence) and have too much shared history. I suspect the only reason they're even hostile right now is because they have absolutely no external threat and are bored. ~~~ Semaphor Fits with what I read on Reddit when it came up. Was a fun fight and TEST won but no one is really mad at anyone else:) ------ stephengillie It's like each solar system is a VM, and they can't move their VMs to a new physical server without disconnecting all clients. And all of their physical servers are at 100% load all of the time? Oh, I guess it's 100% utilization, not 100% load. As in, they don't spin down servers to save power during off- hours I guess. The time dilation is a neat solution to the server load problem, but it's sooo annoying as a player. In beta, it was interesting to watch the entire game desync and grind to a halt, but we could still chat and look around. Interesting, but frustrating. ~~~ alexkus Two main solutions (given that the article mentions that they have huge machines already):- A) Allow a single solar system to span multiple machines. Very hard, especially if the server software isn't architected for this. Retrofitting this can be nigh on impossible. B) Have a few _huge_ machines that can be used to host scenarios like this and, more importantly, have a way of migrating users over to the huge machine seemlessly. The latter can be done but it's tricky, especially if transferring game state between instances of the server is not simple (I'm not talking about transferring the VM itself with something like vMotion). It comes down to:- 1) Being able to make the bigger machine act as a temporary proxy pushing connections data back to the smaller machine. 2) Having a way of telling clients to make a new connection to the bigger machine and, once that connection is made (and the data is being proxied to the smaller machine) cut the connection to the smaller machine. Users see no loss of service or reconnects at all. 3) Once all clients are now being proxied by the bigger machine; pause and transfer the game state from the smaller machine to the big machine and then continue. Obviously it works best if a chunk of state can be transferred in the background and then the final transfer (and pause) is as short as possible in order to transfer over the bang up to the minute state. Option (A) is always the proverbial "In v2 of the server we'll do it a completely different way..." ~~~ dclowd9901 Option 4C) Create a raspberry pi cluster farm, and host every player with one microserver. ~~~ kalleboo How would the microservers keep up to date with each other fast enough to be useful? "eventual consistency" doesn't work with real time strategy games. ~~~ dclowd9901 How would they not? Latency between servers would be near zero, and if they all handled point to point transactions while broadcasting their state on each transaction, you're getting all the power you need. We're not talking about complex processing here. It's an RNG coupled with simple health and xyz. ~~~ kalleboo Broadcasting their state to what? All the other nodes? So each "microserver" would still need to handle thousands of connections and data for every player? ------ ChuckMcM This is a nice article. A friend of mine did some research for DARPA/NSF on internet 'crowds.' His research was looking at the question of fractal gatherings, which was basically you were 'near' the people around you in the virtual 3D space and could hear what they were saying, you were adjacent to people who were one space away but could hear them if they 'shouted' and the crowd was at a gathering that was sharing an experience from a presenter who was 'projected'. Basically a virtual concert venue for example where process affinity scheduling took into account where you "were" in the 3D space. The questions are many and as far as I can tell the folks who research this are few and far between. Process migration continues to be a hard thing to do. VMware and others have made progress, virtualized interfaces and peripherals, self contained 'state'. Works 'ok' at the VM level but still doesn't work at all AFAIK at the 'thread' level. World of Warcraft addresses this somewhat by 'instances' which is that under certain circumstances (entering a dungeon for example) you and your party of 5, 10, 25, or 40 people all transition (through a loading screen) into a place with nobody else (except you). They can dedicate machines to host an instance and do process migration at that level. DARPA is interested of course because they would love to have a way of connecting warfighters into a virtual command and control center regardless of where they are physically. Essentially being in two places at once is a big force multiplier. ------ EarthLaunch This was particularly interesting for me. I've already built a scalable MMO server architecture in Erlang, which hosts all players on one world, using server nodes that can be moved between machines. I calculate that my server architecture can handle up to 10,000 moving players in a local area. That's characters, not EVE-style ships (characters are heavier). If anyone is interested in talking about this, helping, or funding me, please get in touch. My server is called Proxima and my game is First Earth (you can find it if you're interested). I've been slowly bootstrapping it for 3 years. ~~~ outworlder Have you got more details? Links? ~~~ EarthLaunch I haven't been public about my process of building the server or its details (I just don't have time), but the game is at: <http://firstearthgame.com> Someday I'll make time to blog about the server. ~~~ bestes Wow, those screenshots look impressive! ------ DigitalSea I always wondered how Eve coped with what seems like a massively data heavy game, keeping track of battles and logging data especially for epic battles where alliances are pitting their expensive ships against each other. Pretty insightful article, would love to know a bit more about their development processes and how they go about pushing new changes up. It's such a sensitive game, changing just one thing could throw the whole game into disarray. It's crazy when you think that they not only have to track battles, but they also have to capture every other action and movement within the game; mining, agent missions, the marketplace and all of the other components that rely on accurate and up-to-date data capture and realtime reporting. What makes this all even more crazier is the game has been around for over 10 years and counting. I still play Eve everyday, once you get past the menial tasks, you can have some real fun with this game being a drug runner, miner or just straight up renegade roaming the infinite environment. ------ Draiken The environment EVE creates in almost every aspect of the game is just fascinating. It is the only game I ever played I actually felt an enormous thrill and adrenaline rush when playing pvp. It doesn't matter if you're pvping alone or with a fleet. The fact that you actually lose/gain on a fight differentiates the game from any other MMO. Events that you may have experienced in-game can be recorded forever and actually impacts the whole game universe. I really hope more companies invest into having one persistent world in their MMOs. Instead we see this segregated servers in which great players/achievements/events are limited to this little server. It ends up lessening the interest of many players, specially older ones. Funny thing is that, normally, when the hit MMO stops being a hit they end up merging lots of servers anyways. Which IMHO end up lessening even more the time people have spent on that game. ~~~ Scramblejams "The fact that you actually lose/gain on a fight differentiates the game from any other MMO." Could you please expand on this? I'm interested in this point, but I haven't played Eve or other MMOs. ~~~ guizzy For instance; I play Guild Wars 2. If I die, I lose a little bit of in-game cash from having to repair my armor after restarting (less cash than I can make in 5 minutes), and will possibly have to have to trek a couple of minutes back to where I was. But back when I played EVE (that's a very long time ago, the game's changed since)... I was playing as a trucker in low-sec, essentially carrying goods in somewhat dangerous territory. I was really lusting for T2 transports (blinged out trucks), and it was my goal to get one. So I trained and saved for months, until I finally could afford it. I'm not a very patient person, so I took it for a ride before it was fully fitted with the modules I needed for my protection. Some pirate jerk blew it up. It was insured, but I wasn't quite able to easily replace the modules I had lost. In one fight, weeks of my in- game time were lost. In other MMOs, winning and losing can mean that you've wasted a few minutes of your time. In EVE, it can mean months of wasted effort. ~~~ Scramblejams Thanks for your reply. Do you think this game mechanic would work without the availability of insurance? I would think all but the most hardcore would be dissuaded. ~~~ Draiken Well, insurance in EVE does not free you up to suicide your ship. There is a saying in EVE "don't fly what you can't afford to lose at least 3 times". It is a hardcore game, for those who want it to be :) You can always just live in high-sec (safe zone) and probably never lose your ship. Of course the game tends to reward you for taking risks. ------ plasma Second Life (I may be wrong on the game itself) talked about how it manages game scale across many servers. The entire game is a virtual machine. When a player leaves a server boundary, their player VM state is packaged up and sent to the next world server and then resumed on that server. Players don't even notice they crossed server boundaries, and this was possible because the game can be paused mid flight for that player - pretty neat. ------ clarky07 I haven't played EVE in years, but I always love reading these reports to reminisce. It took a huge time investment but it was a lot of fun. Reading that CFC apparently has hundreds of titans and lost 3 just in this battle is crazy. I was playing when the first Titan was built, and I remember distinctly when the first one was destroyed. ------ mseebach On moving the game to a beefier server: _“This is the machine that systems get reinforced on when players request that. Unfortunately, the same thing above applies – anyone in the system when the move happens gets disconnected. Because of this, it’s basically never done,”_ It seems like a fairly small addition to the game logic to allow the game to freeze for a few seconds and be forcibly moved to another server. Is this kind of scenario so rare that it's not worth the trouble, or am I missing something else? ~~~ CJefferson The problem (I believe) is that they don't have a way to 'freeze' and transfer a running game. Think of it like any program -- it is easy to "save your work" and load the file on another computer. It's much harder to exactly save the state of all parts of a running program and transfer that to another computer. Each user is represented by a stackless python program, these are hard to shut down and move. As you say, it could probably be done, but it would be a lot of work, which wouldn't get used very often. ~~~ archon The other problem is that they would have to 'pause' the entire game while the physical move was in progress, otherwise players would still be able to move around in the rest of the game world (other than the cluster of stars they took offline to move them). As I understand it, this is already sort of a problem with the Time Dilation mechanic they currently use; time moves at 10% normal within the fight, giving people outside the slowed-down star systems time to deploy forces at 10x speed relative to the fight. ------ warmwaffles And of course it's a video of the former Goonswarm[GOONS] now [GEWNS] ------ Syssiphus Aww, and now I want to start playing EVE again :). Great article, great battle. ------ OGC This alliance has some guy who does simultaneous translation to russian? ------ dholowiski tl/dr: Sharding and slowing everything down. ~~~ lflux Eve isn't sharded in the common MMO sense. ~~~ dholowiski No, but they talked about disconnecting the battle from the surrounding solar system, and the negative consequences. Essentially sharding. ~~~ lacksconfidence Actually they do not disconnect the battle from the solar system the battle is in. What they said is they run many solar systems on one server. During a major battle they migrate those other solar systems to different servers so that the server only has to deal with the one system. So in a sense, yes, each solar system is its own shard.

German Scientists Create Aerographite, the Lightest Material in the World - japaget http://www.sciencespacerobots.com/blog/71720122 ====== rejuvenile I used to make aerogels (a related class of materials) in high school; allow me to give a (hopefully accurate) layperson's overview. Aerogels formerly held the record for least dense solid. They're not gels, but they're called aerogels because they're made from gels. As the name "aero" implies, they're mostly air, giving them incredible strength-to-weight ratios and insulating properties. Silica aerogels are translucent and quite amazing to hold; it's like holding a cloud. Aerogels are made from colloids (a.k.a. gels), which are long chains of polymers formed in water. Free-floating around in the water, they form very long, intricate, 3-D maze-like structures. If you've ever made JELL-O, you've made (and eaten) a colloid. It’s the intricate structure of the colloid which keeps the suspended water from spilling out. Silica aerogels are formed by removing the water from a silica gel, leaving only the maze like structure behind. This structure is very delicate, and if you attempt to evaporate the water out near room temperature/pressure, the capillary action of water will collapse the structure like a dried out jellyfish. However, if you heat and pressurize the system past the critical point, the water becomes a supercritical liquid and it can be removed without pulling the rest of the material inwards. It appears that what they’ve done here is similar, except they use a multi- step process to deposit carbon on the colloid, then remove the colloid completely, leaving nothing but a carbon maze. I presume they can't make colloids out of carbon directly, hence the multistep process. ~~~ fusiongyro What an awesome hobby that must be! I'd be inclined to try it if I weren't sure I'd kill myself with chemistry. ~~~ Ralith I am certain it's easier than you are imagining. Try it! ------ beambot That's pretty cool. But I'm a bit confused... FTA, _the aerographite density is 0.2 mg/cm3._ From Wikipedia on Aerogel (another very lightweight solid) [1], _The lowest- density aerogel is a silica nanofoam at 1 mg/cm3, which is the evacuated version of the record-aerogel of 1.9 mg/cm3. The density of air is 1.2 mg/cm3 (at 20 °C and 1 atm). Only the recently manufactured metallic microlattices have a lower density at 0.9 mg/cm3._ How are they computing the density of the aerographite such that it doesn't float away (having 1/6 the density of air)? Are they only considering the mass of the carbon and not the internal air?! [1] <http://en.wikipedia.org/wiki/Aerogel> ~~~ ehsanu1 It's probably "evacuated" as well, ie there's no internal air. You can get the weight inside a vacuum so it doesn't float away. ~~~ Ralith If you RTFA, you see there's a video of them sitting on a table in regular atmosphere. You'll also see that it's just basically a very fine carbon hairball. They're obviously measuring the density of the thing itself, and not the air that happens to be drifting through the gaps. ~~~ SilasX Which is to say, they're counting the air passing through the gaps for purposes of _volume_ but not _mass_ in the density calculation. So, could I claim to have the lightest material if I made a hollow, porous, giant hairball? ~~~ sigkill As someone who has worked with metal foams, you are technically correct. ------ Arjuna Here is the press release with further information, video and images: [http://www.uni- kiel.de/aktuell/pm/2012/2012-212-aerographit-...](http://www.uni- kiel.de/aktuell/pm/2012/2012-212-aerographit-e.shtml) Interesting potential for batteries (quoted from above link): _"Due to its unique material characteristics, Aerographite could fit onto the electrodes of Li-ion batteries. In that case, only a minimal amount of battery electrolyte would be necessary, which then would lead to an important reduction in the battery's weight. This purpose was sketched by the authors in a recently published article. Areas of application for these small batteries might be electronic cars or e-bikes. Thus, the material contributes to the development of green means of transportation."_ ------ stephengillie <https://en.wikipedia.org/wiki/Aerographite> _Owing to its interconnected tubular network structure, aerographite resists tensile forces much better than other carbon foams as well as silica aerogels. It has a very low Poisson ratio, as demonstrated by a complete shape recovery of a 3-mm-tall sample after it was compressed down to 0.1 mm. Its ultimate tensile strength (UTS) depends on material density..._ How soon will we see this used instead of metal frameworks or latex foam? In aircraft wings, car seats, etc? Even more interesting: _Upon external compression, the conductivity increases, along with material density_. Pressure-sensitive aircraft wings? Car seats that know what their occupants weigh? ~~~ Ralith > Pressure-sensitive aircraft wings? Car seats that know what their occupants > weigh? Both of these things are pretty easy and cheap to do with existing technology. ------ btipling The research on light and strong materials is key to one day developing space elevators. <http://en.wikipedia.org/wiki/Space_elevator#Cable> I don't know what the strength of this material is or its breaking length (a breaking length of 5,000 km is required for a space elevator), the abstract doesn't say so, but research like this is really exciting. ~~~ ZoFreX I don't understand geeks' obsessions with space elevators. It's not like materials are the only obstacle holding us back - they would be continually bombarded by meteors, and travelling up them would involve extremely long exposure to the high radiation band of the atmosphere. Now launch loops, that I could get excited about. ------ ajays Aerogel (aka "solid smoke") was the lightest so far, at 1mg/cc[1] . The density of air is 1.2 mg/cc. FTA: "The substance weighs just 0.2 milligrams per cubic centimeter" So why doesn't this thing just fly away, if its density is 0.2 mg/cc ? [1] <http://en.wikipedia.org/wiki/Aerogel> ~~~ jws I suspect it is 0.2mg/cc when weighed in a vacuum. It does point out a blurry line between substance and structure. At some point, the voids in the material get large enough that you would call it a structure, for instance, if you outlined a soccer ball in fine copper wire and removed the soccer ball it would certainly be even lighter than this, but you wouldn't call it a substance. ~~~ ars > It does point out a blurry line between substance and structure. It's not new. What is the density of a boat? The density of the boat as a whole is lower than water - so it floats. But if you could only the materials it's made of they are all heavier. So you have to know what you are describing. ~~~ ChuckMcM Exactly and a boat only 'floats' because it holds out the water and thus establishes a pressure differential. If you could put one of these things in a vacuum chamber, then put a seal around the outside of it, and then take it out, it would float. Except what it would really do is compress. And from the article it looks like it would compress to a size which put it into the 3 - 5 mg/cc range if not higher. That said, in Neal Stephenson's diamond age they used vacuum balloons as a floatation device. something that I hope we can build at some point. ------ jere >Think of the Aerographite as an ivy-web, which winds itself around a tree. And than take away the tree. I would totally expect this stuff to be transparent based on the description. Shows what I know. ~~~ tbrownaw The structure is on approximately the same scale as the wavelength of visible light. I think that's in common with other recent ultra-black materials, it's either that there's just a huge amount of surface area or some sort of quantum-mechanics effect. ~~~ rejuvenile Aerogels can have a surface area of ~2,500 m2 g-1, which is incredibly high. I wonder if this material, being made of carbon and likely having a similarly high surface area, would make a good capacitor. ~~~ Someone [https://en.wikipedia.org/wiki/Aerographite#Potential_applica...](https://en.wikipedia.org/wiki/Aerographite#Potential_applications) claims 1.25Wh/kg. I hope that isn't for the lightest variant; in Wh/m^3, that wouldn't be that good. ------ gmack IANAP, but if this material is "jet black", i.e. absorbs most light, and also highly conductive, wouldn't it also be a great component for organic solar cells? Graphene is apparently already an interesting candidate for this application, promising lower costs of manufacture (if not higher efficiency). ------ uncomfytruths If they could turn it into a thread imagine what it could do for the fashion industry. Amazing dresses that flow in the wind even when there is no wind. I'd be worried about strength though. ~~~ padobson Plus one for the least geeky application, and the most marketable I've seen so far in this post. ------ unreal37 I had a dream last week that scientists would someday be able to remove the Higgs Boson from atoms to make truly weightless materials. I should patent that. As far as "flying away", from the video embedded in the linked article, you can see the aerographite is barely able to sit still on the table before the rod is introduced - one of them is about to fly away just sitting there. It just "looks" extremely light. ~~~ Locke1689 The Higgs boson doesn't provide mass to anything, the Higgs field does. The Higgs field also provides a negligible fraction of the mass of baryons. ~~~ InclinedPlane Indeed! The Higgs field provides rest mass to electrons and other fundamental particles. However, most of the mass of, say, a human body comes from the mass of protons and neutrons, and that mass is almost entirely from the kinetic energy of quarks and other nucleon constituents. ~~~ Locke1689 Actually, no. The kinetic energy is a property of the particles (thermal energy, actually), but it does not supply their rest mass. 99% of the rest mass of baryons is due to the strong nuclear force. ------ jhuckestein Think about this for a second. If you wear a tracksuit made of this you'll be able to jump higher than when you're naked. ~~~ jhuckestein Why is this being downvoted? I'm not a physicist but to me this sounds plausible. I think that's pretty mind-boggling. ~~~ archangel_one Same concept as the full-body suits that competitive swimmers wore for a few years (IIRC they are now banned) which made them more buoyant than they would have been without.

Processing Billion-Node Graphs on an Array of Commodity SSDs - gk1 http://highscalability.com/blog/2015/5/19/paper-flashgraph-processing-billion-node-graphs-on-an-array.html ====== Smerity I cannot recommend FlashGraph strongly enough. FlashGraph was one of the first graph computation engines to enable near trivial analysis of the Web Data Commons Hyperlink Graph - 3.5 billion web pages and 128 billion links. For smaller graphs, analysis using FlashGraph is hilariously quick. If you're interested in how this is achieved, refer to [1]. From memory, Da Zheng said he created FlashGraph primarily as he wanted to prove how efficient the storage system was. Full details on the FlashGraph (though FlashGraph runs far faster now!) in the paper at [2]. Note: I'm a data scientist at Common Crawl, the dataset that the Web Data Commons Hyperlink Graph is based upon and the main developer of Flash Graph, Da Zheng, wrote a guest post for us on this very topic[3], so I'm rightfully biased as to thinking this is an amazing project! [1]: [http://www.cs.jhu.edu/~zhengda/sc13.pdf](http://www.cs.jhu.edu/~zhengda/sc13.pdf) [2]: [https://www.usenix.org/system/files/conference/fast15/fast15...](https://www.usenix.org/system/files/conference/fast15/fast15-paper- zheng.pdf) [3]: [http://blog.commoncrawl.org/2015/02/analyzing-a-web-graph- wi...](http://blog.commoncrawl.org/2015/02/analyzing-a-web-graph- with-129-billion-edges-using-flashgraph/) ------ mrry An interesting comparison point: a single core on a late-2014 MacBook Pro can achieve runtimes for the same graph that are within a factor of 4 for WCC (461 seconds for FlashGraph versus 1700 seconds for the laptop). [http://www.frankmcsherry.org/graph/scalability/cost/2015/02/...](http://www.frankmcsherry.org/graph/scalability/cost/2015/02/04/COST2.html) (previously on HN: [https://news.ycombinator.com/item?id=9001618](https://news.ycombinator.com/item?id=9001618)) There are also results for PageRank on that graph, which make the difference more pronounced. FlashGraph runs PageRank in 2041 seconds (I'm assuming for 30 iterations, per Section 4 of the paper), whereas the laptop takes 46000 seconds for 20 iterations. ~~~ Smerity Absolutely spot on - between FlashGraph and Frank McSherry's COST work, the two have really pushed the envelope on efficient large scale graph analysis. Frank McSherry wrote a "call to arms" for the broader graph community at [1]. The main point of interest is that academia generally compared their work with existing distributed graph processing systems, celebrating when any achievements were made, yet not aware of the significant overheads brought on by the distributed approach. Both Frank's work (run on a single laptop) and FlashGraph (run on a single powerful machine) run far faster than the distributed approach and have very few disadvantages. Note: I'm a data scientist at Common Crawl and Frank's graph computation discussion article was a guest post at our blog.

NIST declares the age of SMS-based 2-factor authentication over - Osiris https://techcrunch.com/2016/07/25/nist-declares-the-age-of-sms-based-2-factor-authentication-over/ ====== Matt3o12_ I don't think eliminating SMS authentication is a good idea. While it is vulnerable to social engineering attack (and sniffing if you are near the receiving phone), SMS authentication has proven to be invaluable for most ordinary users. Those users are everything but eager to use anything more secure then their 6 letter password. With tricking many users into using SMS authentication, companies like Google have improved the overall security of most account by a lot. While it is possible to remove an SMS authentication mechanism, it is a lot harder and probably not worth for most accounts. Most people will not bother to install Google authentication and just not use 2FA (who wants to steal their account anyways /s). Even if they did install it, recovering their authentication codes if they have lost their phone is incredible hard (because too many won't use backups – even if it is as simple as apples iCloud backup). What I think companyies should do is give their users a choice not to use SMS authentication. Power users (and hopefully most high profile users) will make use of that and normal user can just use SMS. In the end it is always a trade off between convenience and security and sadly convenience almost always wins for most users even for easy solutions. So we (the developers) should provide them with the most convenient way they accept which offers the maximum security and SMS does just that. ~~~ scrollaway SMS auth is atrociously bad compared to offline 2fa: \- Requires a telecom provider in the first place (in some countries, that legally requires a passport/national ID tied to the phone number) \- Offers no means of backup \- Forgot to disable 2fa on that one account you log into once a year, before changing your phone number? have fun with that Nevermind Google Authenticator. Android and iOS should have a high quality TOTP app installed _by default_. One that permits backups. "Users won't install it" should NOT be a factor and if Apple/Google want their users to start using 2FA it's in their own interest to do this anyway. ~~~ theGimp It's still better than no 2FA, which I imagine is the alternative for the vast majority of people. ~~~ scrollaway Meta: Why is it that in one thread, I'm saying "same-machine 2fa is better than no 2fa" and getting "but but it's not secure!" as replies, but when I complain about sms auth being insecure, impractical, nonstandard and more expensive than TOTP I'm getting "it's still better than 2fa" as a reply? ~~~ Ntrails I agree, it _is_ bizarre to be taking different sides of the argument in different threads... ~~~ ekimekim I want to call this out, because I feel it's a big issue we have as humans trying to engage in reasoned debate - the idea that an inconsistent or changing view is somehow "weak" or invalidates the argument. If someone is changing their opinion, that's a good thing. It means they are taking on board new information and not blindly following their original opinion. If someone appears to have an inconsistent view, perhaps their position is simply more nuanced than the simple "for or against" buckets the debate actively tries to lump all participants into? ~~~ Ntrails Yeah, I was sarcastically pointing out the absurdity of bitching about different people on HN having different responses whilst he himself has slightly different perspectives on subtly different issues... I don't care that his view is inconsistent, I just think the complaint of people disagreeing with him (in a comment format which encourages disagreement more than agreement) was kinda ridiculous :) ------ ams6110 This is the perfect being the enemy of the good. They should be calling for secure, validated SMS. Thinking that "Joe and Jane Six-Pack" are going to use Google Authenticator, is frankly laughable to anyone who does end-user support. But everyone understands "get a text and enter the code here" ~~~ smsm42 Moreover, did you ever try to port Authenticator data from one device to another? There are rumors it's possible. I work in the industry since forever, if anybody can be called qualified for such simple task, it's me. I gave up, too much trouble. Imagining that a regular person would even think about getting into these woods is laughable. Sure _Google_ allows you to port authenticator data with an easy 5-step process. Almost nobody else does even this. Without portability, it means losing access to your Facebook, Instagram and Pokemon Go when you change your device? People would revolt if you do that. So what's the alternative? We either use SMS, or we use email (which will have like order of magnitude higher failure rate with no added security) or we don't use 2FA at all. Or we think really hard and invent better 2FA than SMS that works on every mobile device and is simple for the user. _Then_ we can deprecate SMS. ~~~ bigiain I always refuse to use the "scan QR code" thing, and everybody I've tried that with (at least Google, Amazon, Github, Dropbox, Linode) give you a TFA secret to type in as an alternative - I then store these in 1Password and can back that up and use them to key Google Authenticator on additional devices. (I've never tried to extract or backup.reuse secrets from Authenticator.) ~~~ asuffield This only works for services using TOTP mode; HOTP prevents replay/cloning attacks. ~~~ Rafert The HOTP counter is something you can increment yourself if needed when storing it somewhere? Proper implementations of TOTP do not just rely on expiring the codes. From chapter 5.2 of RFC 6238: "Note that a prover may send the same OTP inside a given time-step window multiple times to a verifier. The verifier MUST NOT accept the second attempt of the OTP after the successful validation has been issued for the first OTP, which ensures one-time only use of an OTP." ~~~ vel0city Yep, right at the top of page 7 of the RFC: [https://tools.ietf.org/html/rfc6238](https://tools.ietf.org/html/rfc6238) If it accepted the same token more than once, it couldn't possibly be called a "one-time password". ------ Kortaggio One of the biggest weaknesses of SMS 2FA that I didn't see the article cover is when an attacker can socially engineer their way into your account with your cell service provider. I'm thinking of a high-profile example when an attacker tried to take over h3h3's YouTube account by requesting his SIM card from T-mobile by pretending to be a T-mobile employee: [https://youtu.be/caVEiitI2vg](https://youtu.be/caVEiitI2vg) ~~~ legohead The other day I forgot my Github password. When I went to go through the password reset process, it must have triggered the 2FA because it asked for my code. I use Google Authenticator, but I had switched to a new phone since the last time I used GA with Github, and never scanned the code on the new phone. So now I'm at an impasse. How do I get the code? Well, Github has a backup -- it will SMS the code to your phone! When it said this I just kind of chuckled to myself as I also had seen the h3h3 video. Sure enough, it texted me the GA code and I got back in control of my account. Github actually provides a list of emergency codes that you can print out and use as a last resort. I had printed these before and actually had them available, but forgot about that process. Github is trying so hard to have your account secure, but yet the SIM card cloning threat is still there. ~~~ bigiain Hint: don't just scan the QR codes on one device, switch to the "type in the TFA secret" mode, and store that in your password safe (this makes it easier to add the key to all your devices too - I have thew Google Auth app in two phones and an iPad. I'd advise against doing that without at least considering something better than a 4 digit pin unlock for your devices). ~~~ danieldk _Hint: don 't just scan the QR codes on one device, switch to the "type in the TFA secret" mode, and store that in your password safe_ I just don't use an authenticator app at all. Some password managers (e.g. 1Password) have support for storing TOTP. So, as long as I can access my 1Password vault (use a strong password!), I can access my TOTP codes. Besides that, I prefer U2F, which is supported by GitHub. ------ wfunction The problem with 2FA apps is that they don't also serve as an instant notification you when someone is trying to log in as you. 2FA SMS does. This needs to be addressed somehow before we declare the former superior. ~~~ lyonlim Instead of SMS, wouldn't email notifications suffice? Apple (iCloud), Gmail and Salesforce does this when there's a new login on a new device. Furthermore, I'm not too in favour of using SMS... I have two numbers and when I don't have both phones with me, it's a huge hassle. I end up setting up my phones to auto forward such smses. I use 1Password OTP support and love how it works seamlessly across my phones. (Edited for clarity) ~~~ gambiting When my Origin account was hacked, I found out that hackers used a very basic vulnerability in Gmail - they've logged into my Origin account, changed the language to Russian, and then changed the password - I received the "your password has been changed" email, but because it was in russian, gmail automatically put it in Spam folder and I never saw it(when I eventually found it the message shown by gmail was "this email is in a different language than used normally for this email address so we've automatically marked it as spam".). Obviously by the time I realized, the "I didn't do this!" link in the email has expired and I had to call EA to recover my account(surprisingly, I did!). So yeah, now I have 2FA enabled on my origin account, but I still wish I received a text message telling me my password was changed. ------ Stratoscope When I think of NIST, the first thing I think of is the old National Bureau of Standards (now NIST) WWV Time and Frequency broadcast on 2.5, 5, 10, 15, 20, and sometimes 25 MHz. (You old-timers can probably hear the radio voice already!) This came to mind because I just read a great PDF with a detailed history and technical description of WWV and its sister stations WWVH and WWVB: [http://tf.nist.gov/general/pdf/1969.pdf](http://tf.nist.gov/general/pdf/1969.pdf) Not directly related to 2FA, of course, but that PDF is recommended reading. These people were hardcore hackers before any of us were born! ~~~ jlgaddis The suffix of my amateur radio callsign is WWV. A few decades ago, when I actually talked on the radio, there would always be somebody who would ask me what the time was. Ironically/coincidentally, nowadays I run several stratum 1 and stratum 2 time servers. ------ viraptor > the verifier SHALL verify that the pre-registered telephone number being > used is actually associated with a mobile network and not with a VoIP (or > other software-based) service Is that possible to do this reliably in any country right now? I know you can easily migrate numbers and the oldschool block assignments don't mean anything in a few countries. ~~~ djsumdog I moved out of the country and depended on my number being on Google voice to use existing services. I'm also curious how to check if a US number is associated with a VoIP services. I worked for an international Telecom whose SMS gateway would just broadcast messages to the two other national providers if the number wasn't there's (the other providers would drop messages that didn't belong to them). That was one of my first assignments; writing a task that would check the ported number database and only send the SMS to the correctly ported provider. ------ niftich Github repo for the working documents: [https://github.com/usnistgov/800-63-3](https://github.com/usnistgov/800-63-3) Issue tracker (discussion/request for comments): [https://github.com/usnistgov/800-63-3/issues](https://github.com/usnistgov/800-63-3/issues) ------ techsupporter > "...the verifier SHALL verify that the pre-registered telephone number being > used is actually associated with a mobile network and not with a VoIP (or > other software-based) service." Now this bothers me. I deliberately use a service (RingTo, discontinued for new users) to park a handful of numbers and be able to exchange SMS and MMS with them. One of the things I do not do is give out my actual mobile number to every random web service that wants it for "2FA," primarily because that now opens me up to even more phone spam. With RingTo, I just set that number to always go to voicemail but am still able to use SMS through their app. It is arbitrary to say "one number type is acceptable for SMS verification but another is not." I'm actually _more_ concerned that my mobile carrier will cough up my account to an arbitrary attacker than I am about some out-of-the- way number parking service that I log into using credentials that are not able to be easily discovered (an alternate e-mail address and such). My mobile carrier is a much larger target _and_ has scores of fallible humans working for it just waiting to be socially engineered. ~~~ greggman I agree. Namecheap currently only supports SMS 2FA. I'm abroad with a local sim in my phone so I registered my Google Voice # with them. It would really suck if I had to carry my USA sim at all times and swap it anytime I wanted to login to those accounts. Ideally they'd support the standards so I could just use one of the many standard OTP apps ~~~ iamshs Same problem. Don't know why namecheap doesn't support 2FA app like FreeOTP. Would make it so much simpler and more secure at least. ~~~ rafaelm They've been promising to implement a better 2FA option for ages. I just got tired of waiting and moved to another registrar. It's a shame because in general, I've never had any problems with Namecheap. ------ sdm It's about time. Phone numbers change too much to be used as part of a reliable 2FA. You go on a business trip or a vacation, you of course get a pre-paid SIM card with a local number in your country of destination. It's simple and straightforward, most airports are lined if kiosks of vendors. But then you can't access any of your services. You can't do your work. 2FA should be based around something that isn't tied your location and doesn't change so regularly. ~~~ _nedR For international travellers, I imagine its a problem. Within a country - it is less a problem. In india at least, we have number portability between providers, so there is little reason to change your number. ------ AdmiralAsshat Good riddance. I live in a basement. I can't tell you how many times I've been scrambling to log into a service that only allows SMS-based 2FA, requiring that I then run upstairs or outside, waiting for my phone's signal to get strong enough that it will receive the SMS, then dash back down before the code expires. ------ tombrossman I'm curious, do people still consider it "two factor authentication" when you have a mobile device generating (or receiving via SMS) one-time codes and that same mobile device syncing passwords? For example, if your web browser or password manager is syncing your passwords to your mobile phone, and that's the same phone the SMS codes or TOTP app runs on, is this completely circumventing the whole concept of "two factors"? Asking for a friend, because I'm sure no HN readers would be dumb enough to do this... (also, The Register covered this same story yesterday, here's my dupe submission: [https://news.ycombinator.com/item?id=12157529](https://news.ycombinator.com/item?id=12157529)) ~~~ chronial See wikipedia: > Multi-factor authentication (MFA) is a method of computer access control in > which a user is only granted access after successfully presenting several > separate pieces of evidence to an authentication mechanism - typically at > least two of the following categories: knowledge (something they know); > possession (something they have), and inherence (something they are). So as long as your phone is sufficiently password-protected, that is is still 2fa. ~~~ tombrossman So a laptop or phone with a fingerprint reader and TOTP app would qualify as well I suppose. I think many people assume that two separate devices are necessary for proper security, and I wonder if this is true? ~~~ vel0city Yes, it would qualify. While having additional devices does increase security (harder to break into both the laptop and a phone, or laptop and smartcard/yubikey/RSA SecurID token) its not entirely necessary. Many physical security systems utilize multiple factors of authentication for access that are tied into a single reader. They often have a badge reader (something you have) and a fingerprint/eye scanner (something you are) or a PIN pad/digital combo dial (something you know) all built into the same device stuck on the wall. Sometimes they'll use separate systems for this, but the combo units are very common. ------ roywiggins I love Google Auth, and SMS really does have security problems, but you need a 2FA method for dumb phones, don't you? Are there Java apps for it? ~~~ niftich Or a hardware token. It doesn't have to be a software token running on your existing phone. That being said, several companies [1][2][3] have in fact made software authenticators that run on J2ME. [1] [https://guide.duo.com/j2me](https://guide.duo.com/j2me) [2] [http://www.aradiom.com/SolidPass/2fa-OTP-security- token.htm](http://www.aradiom.com/SolidPass/2fa-OTP-security-token.htm) [3] [http://www.eset.com/us/products/secure- authentication/](http://www.eset.com/us/products/secure-authentication/) ~~~ BinaryIdiot > Or a hardware token The trouble is with the user (the user is always the problem). What happens if they lose their hardware token? You _must_ have a way to recover that is not exploitable by bad guys but usable by the good people just trying to get back into their account. SMS fills this pretty well despite its security flaws. I'm not convinced hardware fixes this, at least not in any current form I've seen. ~~~ mtgx My bank gives out hardware tokens. It's super easy to use, and I trust it way more than using SMS, even though they tried to push me over to using SMS (probably cost cutting move on their part). When it gets lost, they can replace it. ~~~ BinaryIdiot That sounds like a pretty miserable user experience though. People are forgetful and lose things. Doing something online for the ease of it only to have to wait for something physical seems like a big step backwards as far as UX is concerned. Until you make good security dead simple it'll never be used by the majority. ------ mappu One possible impetus is the rise in SMS phishing like this: [https://twitter.com/maccaw/status/739232334541524992](https://twitter.com/maccaw/status/739232334541524992) How do you verify that the SMS is really from your service? ~~~ BinaryIdiot > How do you verify that the SMS is really from your service? The way the phone system works I don't think there is an actual way. It's inherently insecure from multiple angles. Unless there is a way to verify it, reliably, that I don't know about but I tried looking into this before and found essentially nothing useful. ------ kozak The problem with 2FA is that quite often it will turn into (a weaker) 1FA when users gets a possibility to restore their primary password by the SMS. ------ original_idea Wouldn't PUSH notifications over the Google and Cloud networks resolve this? I know Google Prompt and Authy do this already because of SMS. Authy posted this a couple weeks ago: [https://www.authy.com/blog/security-of-sms-for-2fa-what- are-...](https://www.authy.com/blog/security-of-sms-for-2fa-what-are-your- options/) ~~~ bdcravens Interestingly, when you sync a new device with Authy, one of the options to verify is SMS. ~~~ vel0city IIRC, Authy uses this SMS challenge to authenticate users to allow you to download the database of secrets. This db is encrypted by a passphrase which never leaves the device. So, Authy is using SMS as one part of a multi-auth system to get to the final unencrypted data. That said, anyone with a SIM card able to get messages for your phone number can download the encrypted database and attempt offline passphrase recovery. It might take a while to brute force, they seem to use a lot of hashing rounds as it takes a couple of seconds to verify the passphrase on a 2014 Moto X. ------ pixie_ It's annoying in a lot of services I can't use my google voice number to authenticate. ------ mankash666 Reading through the draft, the level-2 authentication and upwards (AAL-2 [https://pages.nist.gov/800-63-3/sp800-63b.html#sec4](https://pages.nist.gov/800-63-3/sp800-63b.html#sec4) ) spec is encouraging. NIST is encouraging eliminating the password and fully embracing cryptographic authentication (like SSH public-private keys). ------ onetimepassword The biggest threat that other people have mentioned is using social engineering to get a new SIM card that works with your telephone number. I have a google alert for "sim swap fraud". It's oddly under-reported in the US, but quite common everywhere else. How bad is this?? Well, what if at attacker obtained more information about you (ie security questions possibly obtained from a keylogger), then was able to get your phone number, then contacted your bank or other investment broker and drained your accounts? Yes it happens- all the time. It's about time that NIST declares this form of 2FA insufficient. Hopefully the rest of the world will take notice, soon. I prefer OTP... hopefully there aren't any other RSA-type hacks in the future. ------ ComodoHacker What's wrong with SMS to virtual number? I mean how it's less secure than regular number? ------ ittekimasu Coinbase, too hasn't gotten the memo yet. [https://community.coinbase.com/t/can-i-use-google- authentica...](https://community.coinbase.com/t/can-i-use-google- authenticator-instead-of-sms/1104) ------ davidhyde In South Africa, this scenario is becoming a big problem: A victim's cell phone, in their possession, is triggered to go into no-signal state which is sometimes not noticed for hours. During this time, criminals are somehow able to capture communication that would have originally gone to the cell phone. Communication like 2FA passwords. This is then used to transfer money out of the victims bank account. How can 2FA over sms be considered safe if this is possible? ------ Glyptodon It's fine that there are flaws with using SMS, but the alternatives -- proprietary apps, proprietary dongles -- aren't any better. They also just create more parties you have to trust. And if it comes down to using public/private keys, there's no reason an open source SMS app couldn't authenticate encrypted text messages or something. If SMS in the clear is bad (and it probably is), then whatever is okay needs to be broadly accessible, open, and usable. ~~~ WorldMaker «It's fine that there are flaws with using SMS, but the alternatives -- proprietary apps, proprietary dongles -- aren't any better. They also just create more parties you have to trust.» TOTP and HOTP are both open OATH moderated standards. You can use any app or dongle of your choice with any provider that follows the standards. This is a way better alternative than SMS. ------ willvarfar Here's a story about a friend whose phone number was hacked in a banking Trojan attack: [http://williamedwardscoder.tumblr.com/post/24949768311/i-kno...](http://williamedwardscoder.tumblr.com/post/24949768311/i-know- someone-whose-2-factor-phone-authentication) In this case it was a land line, but it's still a relevant empirical data point for those weighing options. ------ Dowwie The list of drafts and request for comments on a range of topics can be found here: [http://csrc.nist.gov/publications/PubsDrafts.html](http://csrc.nist.gov/publications/PubsDrafts.html) Other than the SMS-based 2FA work, see: \- Identity and Access Management for Smart Home Devices \- Multifactor Authentication for e-Commerce: Online Authentication for the Retail Sector ------ xg15 So what exactly is the alternative? I should carry around a physical security token with me for every single account I ever made? ~~~ dchest Get U2F FIDO USB key ([https://www.amazon.com/s/ref=nb_sb_noss_2?url=search- alias%3...](https://www.amazon.com/s/ref=nb_sb_noss_2?url=search- alias%3Daps&field-keywords=u2f+fido&rh=i%3Aaps%2Ck%3Au2f+fido)) [standard, works with Chrome & Firefox for Google, GitHub and more] and/or install Google Authenticator on your smartphone [works with anything supporting TOTP]. ------ xaduha Any 2-factor auth is better than none. ------ forgotpwtomain I'm somewhat surprised NIST is using github (a private company) rather than self-hosting. ------ billpg Does anyone have any experience of using hardware tokens (like the sealed key- fobs) running TOTP? For some services, I would much rather have a key-ring-ful of these devices rather than an app on my phone which I also use for reading websites. ~~~ kabdib I use a mix of \- Google two-factor \- Service-specific two-factor (e.g., Steam authenticator, which provides other features beyond TOTP) \- Non time-based authenticators; Yubikeys are great, and appear to be made of some indestructible material that survives multiple trips through the wash. ------ bdamm Eventually the government will issue identity cards with certificated key pairs. ------ cmurf My bank uses SMS based 2FA. I'll send them this link and reiterate they should support U2F, or at least TOTP supported by Google Authenticator. If SMS is problematic for 2FA, why isn't it problematic for account recovery? ------ retox I never used SMS 2fa because I don't want my phone number out there. ------ ungzd And still in "secure" messengers like Telegram SMS is primary authentication method, not even secondary for 2-factor. Despite documented cases of account hijacks this way. ------ nutanc "For now, services can continue with SMS as long as it isn’t via a service that virtualizes phone numbers" How much of an affect will this have on companies providing such a service. ------ Illniyar I failed to find in the article the reason why it's frowned upon, are there reasons published in the guide? ------ turnip1979 The headline seems a bit click-baity. It seems to merely add some suggested guidelines to how this is done. ------ nxzero If SMS is out, any form of verification or identity tied to phone numbers should be too. ------ tlrobinson > To avoid red tape, the Institute is trying out a new method for reviewing > and commenting on the guidelines that isn’t quite so official: GitHub. Ironically, GitHub uses SMS-based 2-factor authentication... ~~~ petetnt Or alternatively authenticator based 2FA, which is their suggested way. ~~~ lorenzhs Or alternatively U2F, which uses a dongle and is phishing-proof. ------ Kiro I will never ever use 2FA if it's not via SMS. I just don't care enough to be bothered. ~~~ bigiain You've never had anybody try to seriously take over the email account you manage domains names with, have you? (Try owning a domain name with the word "anonymous" in it, and watch the skript-kiddies descend en-mass...) ~~~ dozzie Well, I didn't (I'm not the OP). I host my own e-mail myself. ~~~ bigiain I've been forwards and backwards on that one myself many times... Do you seriously think you're more capable of securing your mail server than Google/Microsoft/Apple? Is the time/effort you'll spend maintaining it worth the privacy tradeoffs? How are you dealing with outbound mail? Where are you hosting your email that isn't already on half the spam blacklists already? (That last one was the killer for me last time I ran a mail server of my own, neither my home ip address, nor any of the Digital Ocean/Hertzner/Linode/AWS vpses I could easily use/afford to make outbound mail connections with were ever trusted by the big email providers. A self hosted mail service that couldn't reliably get mail into the inboxes of 80+% of the people I correspond with didn't end up being of much use... I've ended up back with Gmail and hating myself for it.) ~~~ dozzie > Do you seriously think you're more capable of securing your mail server than > Google/Microsoft/Apple? I don't know about Apple, I stay away from them. I also stay away from Microsoft, but I had to go through some of their products in my time, so there's good chance that I'm more capable. And Google? Extrapolating how they interact[1] with the rest of the world, it's not improbable, too. [1] Did you know, they were a source for backscatter for _several years_? > Is the time/effort you'll spend maintaining it worth the privacy tradeoffs? Wrong question. The correct one would be: why would I give up access to server logs (yes, I use them sometimes) just to give up my privacy on top of that? > Where are you hosting your email that isn't already on half the spam > blacklists already? In a place that is not a known spam source? (Yes, this excludes AWS and Digital Ocean.) ~~~ wtracy >In a place that is not a known spam source? Examples? Shall we take turns guessing the names of these elusive spam-free providers? Your non-answer reads to me as, "Just don't use any providers that you can actually afford, and you'll be fine!" (Sorry if this comes across as grouchy--I can't sleep, and I have to get up early tomorrow.) ~~~ dozzie Well, there are smaller companies with own server rooms that offer VPS-es. I use one in my country (Poland), and I use it since a little longer than Amazon entered our market. I don't think such a regional provider would be of much use to you, unless it operates in your region, of course. What my comment boils down to is to avoid big hosting places. ------ cutie_honey The double-speak and quack-speak is getting a little thick for me lately. Government bodies frown heavily on end-to-end encryption, but also frown heavily on authentication methods that are less secure. Why, whichever directive shall I adhere to? The more secure behavior or the less secure behavior? Maybe I should just do whatever benefits everyone else but me. ~~~ retrogradeorbit Remember this is the same NIST that backdoored the EC coefficients [ [http://safecurves.cr.yp.to/rigid.html](http://safecurves.cr.yp.to/rigid.html) ].

World Renowned Heart Surgeon Speaks Out On What Really Causes Heart Disease - oracuk http://myscienceacademy.org/2012/08/19/world-renown-heart-surgeon-speaks-out-on-what-really-causes-heart-disease/ ====== th0br0 Dwight C. Lundell, M.D. lost medical license in 2008. Since that time he has been promoting books that clash with established scientific knowledge of heart disease prevention and treatment. His book, The Great Cholesterol Lie, invites people to "forget about everything you have been told about low-fat diets, saturated fats, cholesterol and the causes of heart disease." [http://www.quackwatch.org/11Ind/lundell.html](http://www.quackwatch.org/11Ind/lundell.html) ~~~ grannyg00se That's a nice ad hominem collection there. Not one point I could find about his actual claims. He didn't file his taxes properly? Bad patient review history? These things are not relevant to the scientific claims he puts forth. ~~~ bradleyland Ad hominem isn't always a bad thing. The fact that someone lost their medical license is good information when evaluating professional credibility. Professional credibility is absolutely important when evaluating someone's claims. ------ pgcudahy This is pure quackery. The cholesterol -> heart disease framework was developed by the Framingham studies ([http://en.wikipedia.org/wiki/Framingham_Heart_Study](http://en.wikipedia.org/wiki/Framingham_Heart_Study)) that showed a strong correlation between cholesterol and heart attacks and strokes. Now correlation does not equal causation but decades of subsequent studies have shown that cardiac event rates drop linearly with decrease in LDL (a form of cholesterol) ([http://www.nature.com/nrcardio/journal/v8/n12/fig_tab/nrcard...](http://www.nature.com/nrcardio/journal/v8/n12/fig_tab/nrcardio.2011.158_F1.html)). It has culminated so far in the JUPITER trial ([http://en.wikipedia.org/wiki/JUPITER_trial](http://en.wikipedia.org/wiki/JUPITER_trial)) where people with "normal" LDL levels and no history of heart disease were able to decrease their heart attack risk with statins by driving their LDL even lower. The whole inflammation stuff came into play because JUPITER also looked at an inflammatory marker called CRP. Now, that angle is still controversial but could play a role. However, it does not invalidate the dozens of studies linking cholesterol to heart disease. Plus there is nothing linking this guy's quack theories on nutrition to inflammation/CRP or ultimately to heart attacks. I'm surprised that it made it this high on HN. Maybe people just love feeling that "freakanomics" feeling of mental superiority that they're willing to swallow any alternative hypothesis that challenges the norm. Maybe people just don't trust medical science. ~~~ skylan_q _Maybe people just love feeling that "freakanomics" feeling of mental superiority that they're willing to swallow any alternative hypothesis that challenges the norm. Maybe people just don't trust medical science._ I hope it's the case. It was fat, then it was cholesterol, then it was LDL, now it's pattern B LDL that shows a correlation. The ratio of HDL/LDL still factors in as well as triglyceride levels. The jury is still out there as to whether that specific type of LDL is what causes damage or is a sign of damage being caused. To act as if we can say "cut out all cholesterol because it's bad for you" is wrongheaded. We know there is a correlation with these factors as we measure them in the blood. We can't say with a high degree of certainty that eating a certain way will cause a certain effect on people. But when people are taking in over 20% of their caloric intake as saturated fat and showing incredibly healthy cardiovascular health readings, you've got to wonder if the common wisdom is something we should be comfortable with. ------ ceautery That reads too much like baloney. ------ grannyg00se Another slam against overconsumption of sugar and processed foods. This guy may not have the best reputation but the advice doesn't seem all that bad. ------ skylan_q I'm glad that there will be that 1% or so of people who pick up this article and have it change their minds. :) That dietary cholesterol necessarily causes heart damage is taken as a matter of faith. :( ------ nodata tl;dr cholesterol is not the problem, things that inflame the arteries, e.g. high processed carbs and over consumption of certain oils ------ NAFV_P "Well,smokers perhaps, but at least they made that choice willfully." He knows very little about smoking. ------ oracuk In hindsight I wish I had done more than just read this article before I submitted it. A lesson learnt.

Ask HN: What docs to request from SaaS after being laid off? - saas-laid-off I&#x27;ve recently been laid off from a Georgia-based SaaS. What documentation should I request?<p>I did not have any equity, so that simplifies things a bit.<p>Things that come to mind:<p>* compilation of permanent employment record * letter of recommendation * Paystubs<p>I&#x27;m not familiar with what I should expect to have in a permanent record.<p>Any advice or resources would be greatly appreciated. ====== bitshepherd You're overthinking it a bit, and that's understandable. Records and letters, in my experience, are more doing-motions-to-move than actually doing anything. In general, nobody cares if you had a spotless record, or were employee-of-the-interval unless it's a well-known company, in a highly visible situation. Many of these things are simply expected, so long as you present yourself as a level-headed individual that can GTD. At best, they're a conversation point at some point in, before, or after, the interview. Once you're no longer in the employ of a company, it's more or less a done deal, especially in terms of a layoff. Next year's taxes are about the only thing that matter here on a long-term basis, and if they've been paying to UI (legally, they should have been). Mark the point of employment on your personal permanent record (read: your resume/CV/online presence) and talk yourself up a bit in terms of what you've done with honesty. That's one of the hardest parts when you've been freshly laid off. In the immediate future, what needs to happen is ensuring continuity by making sure that you have your UI filed with the state and ready to be processed, while looking for that next place. They tend to ask if you've been looking for work, and you will have to show proof if they ask. The cushion, while it lasts, tends to be helpful in such a time. ------ idoh Those three things are not supplied / needed in my experience.

Mpemba effect: warmer water can freeze faster than colder water - mike_esspe https://en.wikipedia.org/wiki/Mpemba_effect ====== mattdeboard I have no idea what this has to do with HN, but, one of the best "life hacks" I've ever learned was from my Iraq tours: evaporative cooling. If you're outside on a hot day and your drink is hot (in our case, it was palettes and palettes full of bottled water), get a wash rag or a skivvy shirt wet, wrap it around your drink container, and let it sit out in the sun. In a little while, voila, cold drink. Apropos of nothing. ~~~ SiVal It works better in the shade, and best of all in the shade exposed to a breeze. You don't need to warm the water in the rag to evaporate it. It will evaporate in the dry air, even if cool. Putting it in the sun raises its temperature as the evaporation lowers it. If there's a nice breeze, evaporation will still win, but it will get cooler if you don't add energy at the same time you are removing it. ~~~ mattdeboard That's it, it's been awhile (6 years... wow). Thanks for the correction. Heat + breeze (even if the only breeze is warm). ~~~ SiVal +1 thanks for your service ------ InclinedPlane And nobody understands exactly why. The British Royal Society offered a 1,000 pound prize recently for an explanation, so far this is the winner, though it's not complete: <http://www.rsc.org/mpemba-competition/mpemba-winner.asp> ------ sk5t I can perceive this as nothing but a horrible, horrible failure to account for unseen variables. ~~~ gijjk AKA, every unsolved problem in science. ------ ck2 Didn't they prove this happens only if the water is impure? If the water is purified, ie. steam distilled, the warm vs cold effect disappears? ------ slm_HN Back in my high school chemistry class this effect was noted and explained in the following way: Ice needs to form a particular crystalline structure when it freezes. This is what makes ice float in water. The molecules in warm water are moving faster and therefore have a greater chance to wander into this correct formation. The cold water molecules are moving more slowly and simply take more time to find the correct alignment. There wasn't really any proof to this theory, but it was followed with a bunch of anecdotal evidence, like Canadian's washing their cars with cold water, etc. ------ Jach Newton's cooling law can be written as t = -ln(T(t) - Te)/k + ln(To - Te)/k. T(t) is the object's temperature at t, Te is the surrounding environmental temperature that's assumed constant, To is the object's starting temperature, and k is a constant scaling factor related to the material of the object in question. Since this effect is contrary to that law, the law is wrong, i.e. too simplistic. It's not hard to imagine that the surrounding Te is changed by the object or that k of water+container can change depending on its temperature or purity... ~~~ manglav I don't quite follow your reasoning of why the law is wrong. You say yourself "Te is assumed constant", yet you imagine that converting the Te from a constant to a variable could affect the result. However, if you change Te from a constant to a variable, Newton's Law of Cooling is null and void, because a simplification is that Te is constant, and that allows a lot of /dt's to cancel. The law is correct for when you can assume a constant Te, for example an object within a fluid flow (like an airplane wing during flight). The problem is, for stagnant situations, convection plays a _huge_ role in heat transfer within the air. Controlling convection is really really hard, and even harder in a scientific setting that needs to be reproducible. Also, when dealing with transition temperatures, various things need to be taken care of, such as supercooling. This can literally stop working if your beaker is slightly dirty. So the problem is there isn't a way to universally control the conditions for this experiment. However, I did find that the winner of the RSC paper had a suitable explanation that involves the presence of supercooling for the colder sample of water. Essentially, if the colder sample supercools, it will take slightly more time to freeze, because while it should have frozen, the ice does not have a nucleation site. On the other hand, the warmer sample does _not_ supercool, and freezes upon reaching 0 C. This experiment only works if the temperature difference is slight, probably within 15-30 C. Quite ingenious really! Edit: After reading the rest of the comments, air bubble/filtered water/de- ionized water all have great effects on ice nucleation and supercooling, which for me supports the winner's paper. ------ jnellis The controller/thermostat on a stabilized freezer turns on and off in a steady state as it reaches setpoint and then drifts away from it when the motor is off. Filling your ice cube trays with hot water forces the thermostat on sooner, makes it stay on longer because of hysteresis in the controller settings and so freezes faster. That is the only demonstrable reason I have ever seen. ------ drakaal Warm water has less disolved gas, and provides less bouyancy so particulates that would lower the freezing point settle to the bottom. These two factors make the water freeze faster. This isn't "unexplained" unless you never took a college level physics course, which is pretty typical of the people who edit WikiPedia pages. ~~~ derleth Then why did the Royal Society create a contest to explain it? ~~~ drakaal RSC 1000 GBP contests are to encourage youth to develop science experiments. Did you think that amount was enough to finance a study? The 1000 GBP contests are all things for which RSC already has answers. ------ themgt A friend of mine swears that if you're making say a gin & tonic, filling the glass with ice will result in less ice melting and therefore your drink will be colder but less watery. ~~~ nohat That makes sense - the ice cubes are below freezing, so it will take less melting to reach melting point equilibrium temp. In this case you are simply using the heat storage of ice rather than the phase transition energy required to melt the ice. ------ phamilton If I recall correctly, ice frozen after being heated has fewer air bubbles. I wonder if there is a correlation. ~~~ marshray The explanations I heard were that heating the water drove off trapped gases or the warmer water took _longer_ to freeze giving them longer to escape. ------ dsjoerg This is clearly madness. ~~~ etfb All the best science is. Sadly, most of the worst pseudo-science is too, which makes it largely useless as an indicator. Ah well.

Sure, having a nice mascot or graphic mark is great to have, but this software can't solve that problem either (because it can only provide a few pre-drawn marks, which once used by anyone become stale and indefensible as a trademark).

Ask HN: Do you think the "democratic Internet" is over-stated? - aridiculous A recent TED talk explaining YouTube virality says that tastemakers determine the initial spike in views. If a celebrity tweets or a journalist writes about a video, that creates the conditions for virality.<p>It got me thinking that, despite all the talk of a flat democratic Internet, the basic system of hierarchy (or oligarchy) from pre-Internet publishing and media is still fully in place. It's just that different small number of people determine what gets mass exposure.<p>What are your thoughts on this, particularly in regard to how it diverges from the public meme of a truly "democratic" Internet? ====== wmf The term "democratic" is generally over-applied. For example, open source is not democratic — developers have no formal responsibility to their users. (Of course, if it was really democratic you'd have to pay taxes.) I wouldn't call the Internet an oligarchy (it also has random information cascades), but there are definitely power structures at work that are not democratic (or meritocratic). It may be dangerous to believe that the Internet is more free than it really is, because that implicitly legitimizes those power structures. (In other words, if the system is fair and you're winning, you obviously must be winning fairly so let's not question how you got there.)

Ask HN: Choosing an open-source license that's compatible with selling? - speps I am in the process of choosing a license for a projet I&#x27;m doing. I want that code to be used in other open source projects freely. However, if people need to use it for a commercial product, they should acquire the rights from me.<p>What license would fit this? What choices are there? Any existing examples?<p>Thanks. ====== detaro Open-source can be used commercially. Forbidding all commercial usage is incompatible with most definitions of "open-source" and thus all important open-source licenses. Code that can't be used in a commercial product is useless for most open-source projects as well. Generally it is a common pattern to dual-license code as both a) GPL or AGPL and b) a sold commercial license and hope that commercial users prefer to pay instead of dealing with/thinking about the consequences of using the open- source variant. ------ mtmail Those other open projects then need to tell all their users that part of their code has additional restrictions in place, making in incompatible with their licence. ~~~ speps I've seen dual licensed projects before. ~~~ brudgers I am not a lawyer. A common dual license is GPL and a license that removes the copyleft requirement and allows modifications to the code to be distributed without source code. There are a lot of implementation details, for example if part of the code being licensed is GPL, then dual licensing the project can easily run afoul of GPL. My advice is if the project is going to be open source, focus less on a custom license as a way of making money and more on providing valuable service to the people using it. If making money off the license is the goal, then start with a proprietary model and work backward form there over time. ------ brudgers I'm not clear what 'commercial product' means in this context.

Extra domain names? Offer them to fellow news yc'ers here. - acgourley ====== gscott This is the most amazing place to get domain names <http://www.tdnam.com>. Some of the recent ones I have registered using tdnam are ShareCircle.com, RealtyGoLive.com, SharedList.com, SoftwareOutpost.com, UserLinks.com, and AskShare.com. All of them cost $10+$8 to register. People who say good domains are gone are not totally correct. ~~~ acgourley Thanks, that looks nice. ------ acgourley At some point I was thinking of building a quick site to allow people to list/give/swap domain names with a small community of developers. My rational is that many of us sit on a pile of them we bought for past or never-to-be completed ideas, and we could help each other out by making them available. It would be cool if someone did build that side one day, but for now it probably makes more sense to just piggyback on an existing community. Of course I just had several names expire before I thought to do this, but I'm willing to part with: dealray.com mobophile.com mobozen.com I'm not looking for money, but I will ask that you actually plan on using the domain for something cool somewhat soon. The transfer of a domain off 1and1 is a mild pita after all. ------ spking This thread resparked my interest in building a free place to sell and buy domains. I used to frequent Sitepoint's domain marketplace to sell some of my domains or find some good deals, but I hate paying 10 bucks just to list.

If you want me to email you with the link when it's live, please email me at: [email protected] with the subject: Domain Market ~~~ acgourley The important point is that its not just a charity to whomever wants them, because there are many sleezy people who will just scoop them up.

Fiber.js - Lightweight JS inheritance model - krisk https://github.com/linkedin/Fiber ====== ltcoleman I applaud the effort that was taken to build this, but I would hope that none of my devs would approach me with wanting to implement inheritance in js.

I saw a presentation on this and the performance increase was not even an advantage with prototypes because you would have to call a js function 10,000s of times to gain anything. ~~~ krisk Agreed. Although benchmarking performance, in my opinion, is more of a study than a programming advantage. It's to affirm that a model does indeed work without flooding the system with memory intensive operations. The goodness an inheritance model brings has more to do with simplifying code rather than performance.

What's your opinion on websites that "force" users to use modern browsers? - ergo14 I'm about to launch my first SaaS application, it is geared specifically towards webshops, or owners of big sites, in short I don't expect general audience to use my services (basicly webdevelopers) would use it.<p>I strongly believe that web should not be slowed by Internet Explorer, and I want to use features like canvas, css shadows and other properties - without resorting to ugly hacks or image slicing to get a pleasant effect. I know IE9 will support this functionality or other users can use chrome frame if they insist to use IE.<p>Would you find it acceptable to demand from my future clients to use modern web browser?<p>I strongly believe in open technologies and what HTML5 and CSS3 has to offer and would go in that direction. ====== limedaring Why not use things that'll degrade gracefully in less-modern browsers? shadows are awesome, but whatever if they don't show up in other browsers. For example: <http://dowebsitesneedtolookexactlythesameineverybrowser.com/> Now, when it comes to major functionality — if your application simply won't work in IE — you need to decide whether the tradeoff is worth it. You won't be tarred and feathered if you have a giant sign saying people need to use a different browser to use your application. You're simply going to lose users. And note, the vast majority of those users aren't going to download the browser and use your application, they're simply going to leave. ~~~ ergo14 I'm perfectly fine with idea of losing 5 users out of 100 - because 95% of my target base will use modern browser(or less because someone that doesn't use a decent browser will very likely be unable to benefit from my site in first place - specifics of my target group I suppose). Anyways It's not like i'm going to block anyone - I just don't want to support hacky code just to make IE users happy. It's not like the website will be non-functional to IE users - it will probably just be ugly, thats all ;-) Which I guess is fine because its purpose is being a tool for webdevelopers and programmers. Also some features just don't degrade at all ;-) like canvas (unless i use something like excanvas), but this part is competly optional to use, so not a biggie. Think like <https://developer.mozilla.org> \- being made to work in IE ;-) ------ obsessive1 Personally, I don't mind when sites complain about my browser, as long as there is still an element of choice. Not all HTML5/CSS3 features are there in stable versions of a lot of browsers, so if your site were to use a feature only available in the latest stable version of Chrome, for example, and not Firefox, then I would consider that to be too restrictive. However from the sounds of it, your application should work in the latest stable version of the major web browsers, which, in my opinion, is enough. ~~~ ergo14 Indeed, but i would find a common denominator - I would go with features firefox 3.x, webkit, opera + ie9 support. This seems like sane compromise to me. ------ mikecane You're ignoring the many slow computers that are still out there in the world, but perhaps your market won't encompass those. I have an old PC. 1.8GHz Celeron. YouTube complained all the time that I should get a "modern" browser. I was using Firefox 2.x -- which was faster for me than the latest Chrome. Also, Fox could play YT videos, while Chrome and even Safari could not. (I'd tried Fox 3.x early on, but it slowed the entire PC to a crawl and I had to rollback to 2.x!) I forget what frustration I encountered a week ago, but it finally drove me to try Opera. Let me tell you that Opera is sooooo wicked fast on this old PC that it's as if I've had an entire hardware upgrade. I'm not connected with Opera at all, just incredibly happy in using it. Now I can visit sites I had to avoid in the past due to multiple JScript errors (Gizmodo, io9, and the like). If people are hesitant to switch browsers, suggest they try Opera at least once. As usual, TMMV. ~~~ ergo14 Well, I can only say that I don't plan to put anything resource intensive to the layout, i'd risk to say that the website should work fast for you, not sure how well it would look on 2.x, but keep in mind that YT uses flash that is main resource hog(especially on linux). I'm pretty confident that it would run fine on your pc with firefox - because my android phone can run it ;-) That makes me think now i should install fennec on my phone and see how that works. ~~~ mikecane >>>because my android phone can run it ;-) Sorry, but no. I've actually had to transfer some AVIs to my LifeDrive (400Mhz CPU) to play them because they'd be cloggy when using vlc on this PC! (Yes, I've scanned for malware; done _plenty_ of officially recommended optimizing stuff -- which, btw, I should have also said I'm at XP SP2, because SP3 made this machine crawl too!) It could also be I have the crappiest PC on earth, one of very few. ~~~ ergo14 My phone has 560mhz procesor, hadly processing power of your pc. If you are having issues of this kind, maybe thermal sensor on your cpu is broken and cpu is slowing down because it things it has temperature problems, or bad drivers? That 1.8ghz celeron should be fine for majority of tasks. Maybe you could try downloading ubuntu live image and test there if the problem persists(its free)? Then you would at least know if it's not a problem with your operating system. ~~~ mikecane Funny you should mention thermal. Had to replace heatsink retention module recently. But that didn't help anything, really. It's just XP being all clogged up from years of use. Can't do clean re-install. Point of no return. ------ prodigal_erik I'd be ashamed to put out something that completely failed without nice frills like CSS and canvas. Links (the browser) is good enough for Gmail, so that's the level of competence I expect of myself. ~~~ ergo14 Indeed, links is awesome at showing real time charts, I agree. I'm also sure mozilla is ashamed of their new MDN site, and FB for its facebook chat. I need clarify, i want to use it for features, not "bling". ~~~ prodigal_erik A real-time chart is a great progressive enhancement over the raw data. But when I can't get the data even without the chart, that's broken. As for other sites out there, I never claimed my opinions are commonly held. There's a long history of shoddy work succeeding in this industry. ~~~ ergo14 Shoddy is building sites that HAVE to support IE(unless there is really a good reason to do so) - i've done this for years and the only outcome of this is that we contribute to the fact that users don't change their habits and use browsers with shoddy approach to web standards. How can that be better in 21st century? If i'd really want i could support everything, but how long should we keep this up? 10 years? 20? It's like you would say that games should be built to work on 286pc's. Yet no one complains about that (unless it's poor optimization). You were so kind to suggest that my work is shoddy, I would say that shoddy work are websites that use hacks, or use non-semantical markup to archieve the goal of being able to work everywhere. Overall quality of code is sacrifaced for bacwards compatibility with browser that uses 9 year old rendering engine? People switch cars more often than browser versions, I fail to understand why we allow that to happen. We have good solutions to handle legacy app compatibility like chrome frame. Everyone has right to it's own opinion, but is it wrong to want users to use proper browser? Even my phone is capable of rendering charts. How can supporting everyone at all cost be better than pushing for standards? We are forced to standards everywhere in real life, why not in IT? This is a nice quote about what happens if you support broken by design browsers forever: "Facebook explains its decision by saying that many users have complained about unstable chat sessions, or ones that stop completely. In order to improve the way connections are established and messages are sent, however, the social networking giant must make changes that aren't supported by older browsers." I'm not saying that everything FB does is right, but I think that legacy support sacrificing experience of everyone else is not a solution to the problem, and this is a good example. ~~~ prodigal_erik Step one should be valid semantic HTML 4.01 (or equivalently, XHTML 1.0 served as text/html). That's still the current standard, and was carefully designed to be at least accessible on every browser we've ever had. Step two is adding CSS and JS to make the experience nicer for browsers on which it's switched on and known to work reliably. It seems to me that a lot of devs complaining about IE6 have a grudge because it reveals they routinely skip step one. They had every opportunity to build something that always works and always will _and then_ make all the shiny variations they can handle, but they prefer the "this page optimized for arguing with customers" approach.

They are currently working on performance improvements [2]. Quoting from the repo, "automerge is a library of data structures for building collaborative applications in JavaScript: * You can have a copy of the application state locally on several devices (which may belong to the same user, or to different users). Each user can independently update the application state on their local device, even while offline, and save the state to local disk. * (Similar to git, which allows you to edit files and commit changes offline.) * When a network connection is available, Automerge figures out which changes need to be synced from one device to another, and brings them into the same state. (Similar to git, which lets you push your own changes, and pull changes from other developers, when you are online.) * If the state was changed concurrently on different devices, Automerge automatically merges the changes together cleanly, so that everybody ends up in the same state, and no changes are lost.

Interestingly, that extensive post obsessively vivisects RON 1.0 (Replicated Object Notation [2] as of 2017) which was based on columnar compression techniques Automerge recently implemented (53:24 in the talk). Columnar formats have their upsides and downsides, though. [1]: [http://archagon.net/blog/2018/03/24/data-laced-with- history/](http://archagon.net/blog/2018/03/24/data-laced-with-history/) [2]: [http://replicated.cc](http://replicated.cc) ~~~ lann It's worth noting that you are the author of RON :) ~~~ gritzko ... and working hard to release the new version. Hearing the fuzzer buzzing as we speak... ~~~ archagon Are there changes coming to RON that aren't currently mentioned on [http://replicated.cc](http://replicated.cc)? Any clues as to what they might be? ~~~ gritzko I think, the new RON oplog is the biggest change. ------ mike_red5hift Does anyone take issue with the fact that CRDTs seem to require keeping a history of every change ever made to the document? Seems like it could get unwieldy very fast. Especially, in the face of a bad actor spamming a document with updates. I've considered using CRDTs in a few projects now, but the requirement to keep a running log of updates forever has ruled them out. I've ended up using other less sound (more prone to failure), but more practical methods of doing sync. Perhaps, I'm missing something. Wouldn't be the first time. Are there alternatives without this requirement, or that would at least allow a cap on the update log? ~~~ appwiz > I've ended up using other less sound (more prone to failure), but more > practical methods of doing sync. Could you share the alternative methods that you’ve used? ~~~ mike_red5hift Stuff like diffing multiple json documents and merging adds, updates and deletes where conflicts did not exist and overwriting conflicting attributes based on timestamps (latest wins). There's some reasonably good jsonpatch libraries out there that will do the heavy lifting. Plenty of room for problems to arise, but it did not require keeping a log of updates. My use cases did not require real-time collaboration and the structure of the document was known beforehand, though. ~~~ appwiz Got it. I’ve typically seen Operational Transforms brought up as the alternative to CRDT for real-time collaboration. But, if you don’t need to solve for that use case and the format is JSON, it’s a different problem to solve and you don’t need that journal of changes. If you have code available in the public domain, I’d love to see it. ------ infogulch There was a recent post of a series that dives into CRDTs [1] . Someone linked to a paper, _Chronofold: a data structure for versioned text_ [2] dated this April, that attempts to map CRDT semantics onto text editing. It's still on my list. [1]: [https://news.ycombinator.com/item?id=23737639](https://news.ycombinator.com/item?id=23737639) [2]: [https://arxiv.org/pdf/2002.09511v4.pdf](https://arxiv.org/pdf/2002.09511v4.pdf) ------ alextheparrot This spawned an idea, which I feel a need to post. It seems the hard part about CRDT is choosing the correct commutative function, as merging two operations in line with user intent is non-trivial. Would it be possible to use a combination of superposition (Please correct me if this word is wrong) and pruning to derive user intent? The idea being that instead of combine being (A, A): A (A commutative semigroup), couldn’t we represent the operation as (A, A): Set[A] and have a way of showing the user set results in a way that their next operation shows us the “correct” interpretation. He’s doing this implicitly with the file tree example, wherein operations that don’t create trees usually defy user expectations (Symlinks aside), so he decides to prune those choices from the result Set[A] before introducing a heuristic to further prune the set. There’s still an issue of users having opposite intent, but at that point it just seems like we need to introduce “Set pruning” or “Superposition collapse” operations as a user-level primitive and then rely on recursion to resolve the possible nesting of these result sets. Does this riff with anyone / does anyone have further thoughts on this formulation? ~~~ benrbray This sounds similar to the concept of a "multi-value register" [1] I've seen in a few places while reading about CRDTs the last couple days. Is that what you're looking for? The idea is that each process maintains a vector clock with the latest timestamp from all other processes, and we don't delete values until one version can be verified to be "later" than all the others. [1] Section 3.2ish of [https://hal.inria.fr/inria-00555588/document](https://hal.inria.fr/inria-00555588/document) ~~~ alextheparrot This was 100% the path I think I was traveling (Thank you for the link). I had a hard time grocking the complete specification from the paper, but the README of this repository that implements CRDTs in that frame was helpful [1]. The core part is separating the "merge" from the "resolve" state. Merging state can be done in a variety of ways, so in the default formulation there seems to be a focus on making the "merge" operation also "resolve" to only one value, when really there could be multiple formally valid merges that the client may desire (Which is part of the difficulty that the video notes as he proposes a variety of possible file system mutations for a set of two uncoordinated operations). The cleanest clarification of my thought process is similar to the following: Given the operation Merge(4, 2), I could propose that there are two valid ways to perform this merge, addition and multiplication. This means the result would be either 6 or 8. The act of returning a single value (6 or 8) changes that proposal into a statement, though, which is the "resolve". One subversion of this restriction is to return a set of all possible results for the operations we think are valid, so {6, 8}. At this point, the user can say (Either explicitly or implicitly) "I actually want 6" and we resolve it to the single value of {6}. There are also special cases like Merge(2, 2), where this whole situation is especially ergonomic because the merge operations are equivalent. There are problems, of course, with this approach. One issue is the need to categorize all possible operations the user may think are valid for Merge(4,2). If the user intended to do division, the result set proposed above will not include the state that they would expect. Still, this seems more general now, as we just need to gather the set of operations that the user may think are valid instead of assuming which one is valid. There's also a ranking problem that then exists at the UX level, as we need to find a way to cleanly propose this set of alternatives. Another issue is, of course, exists if both users propose conflicting resolutions (Actor1 says "I want multiplication" and Actor2 says "I want addition"). This is the issue with decoupling the "merge" and "resolve" steps, as now we may cause a fork in the model which causes a fundamental divergence of the collaborator's data. [1] [https://github.com/rust-crdt/rust-crdt](https://github.com/rust- crdt/rust-crdt) ------ sfvisser From my (admittedly very limited) experience implementing CRDTs it became clear that even technically correct is not good enough. Optimistic merge strategies require a very clear understanding of user intent and expectation. Properly consistent can still mean utterly confusing. ~~~ topicseed Exactly that which is pushing many people away from CRDTs despite them being mathematically proven true, and towards Operational Transformation. ~~~ heavenlyblue OT is just a fancy name for a CRDT. ~~~ sagichmal No, it isn't. ------ hencq First off, this is an excellent talk. The presenter explains the different topics in a way that even a layman like me can easily follow along. The compression scheme he presents at the end seems very interesting as well. I do wonder if in practice OT isn't a simpler solution for most applications. He mentions the differences in the beginning of the presentation and the main advantage of CRDTs is that they don't need a central server. It seems to me that for e.g. a web app you have a central server anyway so all the extra complexity of CRDTs isn't needed. I know almost nothing about this though, so would love for someone more knowledgeable to explain why I might be wrong. ~~~ vivekseth For single server/database web-apps, CRDTs might be useful because they allow offline edits, and (to me at least) they are simple to understand and implement. OT does allow offline edits too, but (I think) has poor performance if there are many offline edits. For multi server/database web-apps, CRDTs might be useful because they reduce the centralization required for collaboration, and increase the fault tolerance. In a load balanced web app, different clients could connect to different servers/databases and stil achieve eventual consistency when those back-end systems sync up. If any of those systems go down, in theory traffic could be routed to other systems seamlessly. ------ migueloller I recently shared a thread [1] on Twitter with CRDT resources I found useful if you’re interested in that kind of thing. [1] [https://twitter.com/ollermi/status/1279067350269124609?s=21](https://twitter.com/ollermi/status/1279067350269124609?s=21) ------ sradman CRDTs are great examples of what the NoSQL movement called Eventual Consistency. I never understood why this movement assumed that abandoning ACID-style consistency automatically gave you Eventual Consistency. As a side question, have any new algorithms been developed over the last decade that have significantly improved automatic source branch merging? ~~~ Taek Eventual consistency and ACID are not at odds, you can have one or the other or neither or both. ~~~ dboreham Not true. Eventual consistency can not (provably) provide consensus. ~~~ IggleSniggle sure it can! A particle can be _either_ this or that until someone looks at it, and when they do, the act of looking at it causes the state to collapse and propagate. Sure, a partitioned group may come to alternate realities before they reunite, but then you just get to do the same thing again! Like Conways Game of Life, except with application state. (I am joking of course) ------ benwr If anyone is interested, I've been trying to think about the problem of moving ranges in a list-structured CRDT for a couple of weeks now for a side project, and I've got a candidate that seems to satisfy the most obvious constraints. I'd be really interested in any feedback / holes you can poke in my solution! Rough notes are here: [https://docs.google.com/document/d/1p1K3sxgKGYMEBH72r-lnP9Gn...](https://docs.google.com/document/d/1p1K3sxgKGYMEBH72r-lnP9GnBm5N15h77C81W15kPiE/edit?usp=sharing) ~~~ anchpop This is interesting! I've been looking for a good sequence crdt to implement in my Rust CRDT toolkit [0], which is still very much a work in progress but I want to make it really useful. Do you know how this compares to yjs [1]? [0]: [https://github.com/anchpop/crdts](https://github.com/anchpop/crdts) [1]: [https://github.com/yjs/yjs](https://github.com/yjs/yjs) ~~~ benwr I hadn't looked at yjs; I'll check it out! [edit: It looks to me like yjs is much more flexible than my design here, but doesn't include an ability to move ranges of lists to different locations] Darn, and just after I'd implemented it myself in terrible beginner Rust! I might get started reimplementing it using your tool :) ------ mdptt What an excellent talk, many thanks. One idea comes to my mind (a bit out of topic): as we can store the complete editing history in a document (even including mouse movements) with a fairly small overhead using the ideas of automerge, would this be useful for distinguishing texts that are generated by machines and by humans? Or to detect plagiarism? ~~~ williamstein I wrote the realtime sync and edit history code in cocalc.com, which is used by instructors to teach courses that use jupyter notebooks with realtime collab. Instructors do regularly suspect and diagnose instances of cheating by students due to us storing the complete edit history. We don't automate this - it's more that they are grading, get suspicious, and use the edit history manually to investigate further. ------ 6510 I thought about this once and came to the conclusion that the problem doesn't exist: Anger is the only thing you can accomplish by typing letters into the sentence I'm writing. If the goal is not anger but to write text only one person can write a sentence at a time. The solution then becomes really simple: You insert your cursor where you want to edit. You wait for the text and/or background of that paragraph to change color. Light green would do nicely. Other users will see that paragraph turn red. The paragraph is now under your control. If someone else desires to edit a sentence in YOUR paragraph that sentence changes color again and the side bar displays a dialog allowing you (the owner) to 1) hand over the paragraph to the new author, 2) hand over only that sentence or 3) ignore the request. Dumb software wins! ~~~ sleepinseattle That falls apart as soon as the author with the locked paragraph leaves the document open while they’re doing something else, preventing others from editing. ~~~ Ozzie_osman Or if network connectivity isn't guaranteed. ~~~ 6510 I really don't get it. You want to add thousands of lines of code and complex data structures with tons of edge cases so that I can interrupt you while you write??? It's just not desired functionality. Poor network connectivity is not an excuse to break your workflow. You simply do not assign 2 people to a task that can only be done by a single person. It is like a system where 2 people can poor coffee into the same cup at the same time. We deal with the cup overflowing with some drainage (marvel at our creation of course!) but then 12 people put sugar in the cup. Solution: we overflow the cup further to dilute it! We solve the mobility issue by spilling a bit more coffee out of the cup and whip the bottom with just the right type of towel or napkin. The only problem that remains is both drinking from it at the same time. ------ sillysaurusx Hmm. Does anyone know of a transcript? I can’t watch right now, only read. I wonder if there’s some free YouTube transcription service... even just showing the captions would work. Oh, hm. It’s not on YouTube anyway. ~~~ benrbray Actually, the video on the page is a YouTube embed and the English captions are pretty good (although understandably it struggles with CRDT jargon). I found that the last 4-5 references listed in the link are pretty accessible, and most of the diagrams from the talk are taken from one of the papers by Kleppmann. ------ archagon Great talk! I look forward to diving into "Interleaving anomalies in collaborative text editors" to see how Kleppmann et al fixed the RGA interleaving issue. The section on moving items in a list makes my mind jump to Causal Trees (≈RGA). The problem here is that a) we need the concept of a list bucket or slot, and b) we also need to preserve the sequential integrity of runs of items as in text editing. In CT/RGA, each letter/item is simultaneously a list bucket and its contents. I wonder if this problem could be solved by adding a "reanchor" op that moves the "contents" (and some/all children) of a letter op to the "bucket" of another letter op? Each reanchor op would have the job of "moving" a subtree of text to a new parent bucket. (Under the hood, the subtree would obviously remain topologically unchanged for convergence purposes, but the reanchor op would inform how the tree is parsed and turned into a user-visible list or string.) First, the reanchor op would need to reference the start and end letter/item ops in a given subtree; and second, the reanchor op would need to reference the letter/item op into whose bucket the subtree contents will be moved. If the set of subtrees for a range of text/items contains multiple independent subtrees, they would each need their own reanchor op. Concurrent moves of the same subtree would be resolved as LWW, similar to the Kleppmann proposal. Let's say you have a graph for string "ABCD" that looks roughly like this, sans metadata: +---+ | A | ++-++ | | v--+ +--v +---+ +---+ | B | | C | +---+ +-+-+ | v +-+-+ | D | +---+ If you wanted to move "CD" after "A", you would add the following op: +---+ | A +<---------+ ++-++ | | | | v--+ +--v | +---+ +---+ | | B | | C +<---+ | +---+ +-+-+ | | | | | v | | +-+-+ ++-++ | D +<--+ m | +---+ +---+ "m" references "C" and "D" as the subtree range, and "A" as the target bucket. The string would render as "ACDB". We can get cycles with this scheme, but as far as strings or lists are concerned, this doesn't actually matter, since the parent references aren't reflected in the output (as they would be with an explicit tree data structure). If, concurrently to this, another device wanted to move "A" after "C", the merged graph would look like this: +---+ +---+ | m +-->+ A +<---------+ +-+-+ ++-++ | | | | | | v--+ +--v | | +---+ +---+ | | | B | | C +<---+ | | +---+ +-+-+ | | +---------^ | | | v | | +-+-+ ++-++ | D +<--+ m | +---+ +---+ How does this get resolved? Well, we can simply read this as "move the contents of 'A' to the bucket for 'C', and move the contents of subtree 'C' through 'D' to the bucket for 'A'." The string would consequently render as "CDBA", as we would expect. This is just a sketch, not sure if it would actually work in practice. Pain points are a) moving multiple subtrees in a somewhat atomic way (when the range to be moved covers more than a single run of items), b) sane results when overlapping ranges are moved concurrently, c) moving items to a bucket whose contents had already been moved before, and d) parsing performance, especially given the fact that we'll now have ops (and their children) whose contents might end up in arbitrary places in the output string or list. Might just end up with a slow, confusing, and labyrinthine data structure. There's also the question of intent: does the user want to move a range of items to the slot currently occupied by a different item, or do they want to move that range to the right of that item? Lists of notes will want the former, while strings will usually want the latter. Perhaps the reanchor op could explicitly differentiate between these two cases. ~~~ martinkl Interesting idea, but the devil is in the details. Especially two concurrent moves of partially overlapping ranges of characters is a tricky case to handle, and it is not obvious to me how your scheme would deal with this. Another fun case is two concurrent range moves in which the destination of the first move falls within the second move's source range, and the destination of the second move falls within the first move's source range. How do you handle this? I expect that any algorithm solving this problem will need a formal proof of correctness, because it's very easy to miss edge cases when using informal reasoning. ------ jwr Incidentally, Martin's book ("Designing Data-Intensive Applications") is excellent and highly recommended reading. If you find yourself saying things like "this database is ACID compliant", "we have an SQL database with transactions, so we're fine" or "let's just add replication to Postgres and we'll be fine", you need to read this book. ~~~ swyx > If you find yourself saying things like "this database is ACID compliant", > "we have an SQL database with transactions, so we're fine" or "let's just > add replication to Postgres and we'll be fine", you need to read this book. can you elaborate why? are these sentences fundamentally wrong? they dont appear so. ~~~ robto The entire book is about when and how these statements turn out to not be absolutely true. And it's not a short book. I don't have my copy in front of me right now, so I won't get into specifics. But I consider it one of the most important books I've read, if only for making me realize how difficult it is to get distributed systems correct. Or, rather, learning that getting distributed systems correct is impossible and what sort of tradeoffs you can make in order to keep things mostly working. And it turns out that most services that I find myself working on these days are distributed systems, so having a healthy respect for all the ways things can break is a useful place to be.

I drink a lot of tea... _47 year old woman...drank a pitcher of tea made from at least 100 tea bags daily, for 17 years_ Whew, not even close. Also, WTF. Glad to see that simply halting the excess consumption should allow her body to repair the imbalance over time. ~~~ YokoZar At some point you wonder if putting more teabags into the same pitcher doesn't actually make it any stronger. There's gotta be a saturation point for tea solutes. Except maybe for the flouride in them. ~~~ eksith It stops being stronger at some point I think. The water can only hold so much of the infusion. I have no scientific evidence other than my own observations -- and that's far from scientific. "Too much" is generally a relative term depending on where you're from (although this lady didn't fit the customs of the locale) since people drink it both in the morning, evening and stometimes in the afternoon. These cases also tend to show up in Sri Lanka, which has a tea culture as well. We also need to keep in mind that some areas have naturally high levels of fluoride in the groundwater. Without reading the detailed article (TBA), it's hard to tell if that played a part too. Edit: Something smells fishy. _Pass it on: A 47-year-old U.S. woman developed a bone disease after drinking a pitcher of tea a day for 17 years._ The actual case hasn't been published in detail and the link to the case : <http://www.nejm.org/doi/full/10.1056/NEJMicm1200995> But it mentions: _Brewed tea has one of the highest fluoride contents among beverages in the United States._ I'd like to see some actual backup of that with hard data. ~~~ phaus When I make tea, I find that as little as an extra 3g of tea, or an extra minute of steeping can ruin an entire pot. I can't imagine dumping several ounces of dried tea leaves into a single pot of tea, which is pretty much what this lady was doing. ~~~ eksith Agreed. At the most, tea should be left to infuse for 1 minute (loose tea less than that), especially for Black tea blends. Any more and it just kills the flavor. I'm willing to bet she was doing it for some sort of DIY health thing. People do silly things like over-doing something if they think it's good for you. Well, that then makes it bad for you. There's a great book on all this called The Book of Tea by Okakura Kakuzo : <http://en.wikipedia.org/wiki/The_Book_of_Tea> A very good read on the subject. I think Google Books probably has a free translation. ~~~ eru > Agreed. At the most, tea should be left to infuse for 1 minute (loose tea > less than that), especially for Black tea blends. Any more and it just kills > the flavor. Depends. I can leave my Pu-Erh in overnight, and the flavour is still fine. (But Pu-Erh is well known for that.) ~~~ eksith Pu-erh is not like ordinary loose tea so it's quite safe to do that. Without stirring or pressing, you don't get too much of the flavor into the water and it's much more coarse. You'll find a lot of the green teas also don't over- flavor the water because of this. ~~~ eru Yes. I guess your 1-minute rule is more appropriate for black teas than anything else. I like my teas more overbrewed in any case. ------ acabal Too much of anything is going to mess with your body. I would have been surprised if drinking the equivalent of 100 tea bags daily for 17 years _didn't_ mess this woman up. ------ Shenglong I am disgusted that they chose to measure _tea_ in _bags_. /teasnob ~~~ eru Yes.

I don't have much faith in the number10.gov.uk petition page. The number 1 petition there was for Gordon Brown to resign [1],[2] Despite getting more than 72,000 signatures, the response [3] was more like a boilerplate reply.

It's hardly likely a Prime Minister would resign based on an online petition though. ~~~ philh The Turing apology wasn't something anyone in power cared about. Granting petitions like that makes them look benevolent (and us feel empowered), but doesn't interfere with their plans. ------ tom_rath An e-peititon is going to do nothing. This nonsense distracts people from actual effort and helps bills like this get passed. If you want to make an impact, the minimum you should do is write a letter to your MP, on paper, sign it and send it to them by post. Letters and phone calls (but particularly letters) are the currency your MP uses to gauge public opinion. Use them. ~~~ bumblebird I think the whole point of the government petition website is to gauge public opinion. I think it'll do more than 'nothing'. I'd agree though, write letters as well. ~~~ tom_rath It actually does less than nothing. Since an e-petition site like the one linked gives people opposed to an issue the impression that they've accomplished something, those people are that much less likely to do something substantive to resolve the issue they're concerned about [Citation_Needed -- I couldn't be bothered to find it]. So, less is actually done to oppose the issue than if the site never existed in the first place. It actually _helps_ those who are in favour of the issue opposed. E-petitions aren't useless: They're _worse_ than useless. ~~~ bumblebird How about all the times the e-petitions on number10.gov.org have been reported in the mainstream media? Now each article which reports on the issue will be able to say "An issue which has seen X sign a petition against it". Also it's likely to make the news in more places. ~~~ eswat But how many of those e-petitions with the media traction actually got meaningful results, other than making the news in more places? ------ RiderOfGiraffes Done. ~~~ pierrefar Hardly. It's promising to be a long slug.

IPhone Push Notifications for any IMAP account - talison https://msgpush.com/ ====== modoc The privacy concerns here are obvious... Neat service otherwise, but I don't trust too many people with my e-mail. ~~~ RK People seem to be very loose with their account info these days when it comes to convenience. You'd never give your password to someone if they asked you in person, but if it's a website, that's a whole different scenario. ~~~ patio11 You wouldn't. I wouldn't. We are not most people. Many people will give their password to anyone who asks, and most will give their password to someone who offers them a candy bar. <http://news.bbc.co.uk/2/hi/technology/3639679.stm> ------ whalesalad An open source self-hosted implementation of this would be terrific :) I too would not trust this service, it seems pretty fly-by-night. ~~~ modoc Yeah, I'd love to be able to add real push notifications to postfix. ~~~ strlen I think you meant something like dovecot, instead. Postfix is an MTA, not an imap daemon. I'd _very much_ like to see a dovecot extension to do push. ~~~ modoc Yes sorry:( Up too late on a deployment. Dovecot is great. ------ jsz0 Has it been entirely proven that the iPhone only checks IMAP accounts on a 15 minute interval? I've never stop watched it but I feel like it's much shorter. I've seem some speculation that it depends on wifi vs. 3G connectivity. It seems to me that messages show up in my desktop client (IMAP-IDLE aware) only a few minutes before they hit my iPhone. My gut feeling is the iPhone is probably 3 or 4 minutes behind my desktop client (IMAP-IDLE aware) Has anyone been able to confirm or deny the 15 minute interval or is it just my imagination and poor sense of time? (I do have a separate MobileMe e-mail account account as well. Perhaps it changes the IMAP intervals system wide?) ------ steadicat Doesn't work if you're also using Google Sync. The iPhone will only let you add one "Exchange" account. We just have to wait till Google implements push for Gmail. ~~~ Skeuomorph Far as I can tell, this isn't an exchange account, just an unread email badge. I say far as I can tell, because during the registration, when I saw they were asking for password instead of using SSO, I abandoned. ------ bharris If you choose to disregard the privacy issue, don't get too attached. Their privacy policy states that they plan to charge for the service once it's out of beta: _"Information collected may include: contact information such as your name, phone/cell numbers (during the course of technical support incidences), e-mail address(es), e-mail password(s) (to monitor your mail account for new messages), an identifying question for security check purposes, billing information (if you choose to join our service post Beta) and information related to those of our service(s) in which you have expressed an interest."_ ------ zain I really wish they had _any_ information about the technical details behind this. Do they mirror your email on their exchange server or something? ~~~ nudded They don't mirror your mail, you receive a pushed mail on the msgpush account telling you new mail has arrived. You still have to read it on your regular account ~~~ nailer What protocol do they use on the msgpush account? Push IMAP? Something else the iPhone supports? ~~~ Skeuomorph Yes, "something else" the iPhone supports in OS 3.0, which is "push notifications". These is a background notification service any iPhone app can use that can show a text message on the screen and update a counter (aka "badge") on the icon of an app that isn't running. Push notification in iPhone OS 3.x is not to be confused with Exchange or ActiveSync so-called Push email. ------ jasonlbaptiste Is there a jailbreak way to modify the settings so it checks it faster than every 15 minutes? ~~~ nailer I don't understand - isn't this push? Shouldn't you be notified immediately, rather than pulling every 15 minutes? ------ yan This service/app will fall apart as soon as Apple adds this feature. ~~~ Skeuomorph Apple would prefer for you to use Mobile Me.

International Obfuscated C Code Contest Winners - lelf http://www.ioccc.org/years.html#2012 ====== biot Tromp's entry is amazing. Source: <http://www.ioccc.org/2012/tromp/tromp.c> Spoiler: <http://www.ioccc.org/2012/tromp/hint.html> It's based on a minimal implementation of Binary Lambda Calculus: <http://en.wikipedia.org/wiki/Binary_lambda_calculus> ~~~ batgaijin Did he _invent_ Binary Lambda Calculus as well?!? ~~~ jlgreco "Binary lambda calculus is a new idea introduced by John Tromp in 2008" Apparently so. Wow. ------ ioccc We hope you enjoy the 21st IOCCC results - we enjoyed judging the entries. If you have any feedback on the competition for the Judges, please contact us using the details at <http://www.ioccc.org/contact.html> Thanks. SimonC. ~~~ wtracy Just curious, since you're handy to ask: How do the judges view code that depends on external (but cross-platform and FOSS) libraries? Only Xlib is specifically mentioned in the rules. I'm specifically thinking of libpng, but I'm sure one could think of other meaningful examples. ~~~ dlowe I don't know the official policy, but anecdotally, I won with an entry that used libperl back in 2000: <http://www.ioccc.org/years.html#2000_dlowe> ~~~ Natsu I love this bit of history from the hint :) Aside: history... Larry Wall wrote the original Perl in 1986-87, the same two successive years he won the IOCCC. I hope this program helps you to realize that this was no fluke - that Perl and Obfuscation are as inseparable as, say, camels and humps. ------ dlowe FWIW, if anyone is curious to see the process of building my entry ("Conway's game of death") I just made the repo public: <https://github.com/dlowe/death> This contest is great. I'm so glad it's happening regularly again :) ~~~ omoikane Process of building my entry is mostly in spoiler.html.gz. For your viewing convenience, it's also here: <http://uguu- archive.appspot.com/nyaruko/edit.html> ~~~ dlowe How did you record that? ~~~ omoikane A VIM script snapshots the file every so often, and another program turns the recording into HTML. Package for both is here: <http://uguu.org/arc_homura.html> Manual: <http://uguu-archive.appspot.com/homura/manual.html> ~~~ dlowe Fantastic. Thanks :) ------ kqr2 There's actually a book that covers some of the old contest winners: _Obfuscated C And Other Mysteries_ by Don Libes [http://www.amazon.com/Obfuscated-Other-Mysteries-Don- Libes/d...](http://www.amazon.com/Obfuscated-Other-Mysteries-Don- Libes/dp/0471578053/) ~~~ johnx123-up My all time favorite is Wesley's code in 1992 that prints world map (found through _A to Z of C_ ): main(l ,a,n,d)char**a;{ for(d=atoi(a[1])/10*80- atoi(a[2])/5-596;n="@NKA\ CLCCGZAAQBEAADAFaISADJABBA^\ SNLGAQABDAXIMBAACTBATAHDBAN\ ZcEMMCCCCAAhEIJFAEAAABAfHJE\ TBdFLDAANEfDNBPHdBcBBBEA_AL\ H E L L O, W O R L D! " [l++-3];)for(;n-->64;) putchar(!d+++33^ l&1);} ~~~ pooriaazimi Care to share the output also (for those who don't have a C compiler handy)? Thanks! ~~~ zer <https://gist.github.com/3910435> ------ saint-loup Fun fact: David Madore, co-author of the conspiratorial contest, actually didn't mean to obfuscate his code. The winner page: <http://www.ioccc.org/2012/grothe/hint.html> The source in french: [http://www.madore.org/~david/weblog/2012-10.html#d.2012-10-1...](http://www.madore.org/~david/weblog/2012-10.html#d.2012-10-14.2083) ------ 16s deckmyn.c is my favorite. That's beautiful source code. Edit: This one is fun to look at too: <http://www.ioccc.org/2012/hamano/hamano.c> ~~~ makomk hou.c is kind of neat too. Looks like a big blob, but actually forms an image via cunning use of syntax highlighting. ~~~ rlt3 Is it supposed to be Kyubey? I pulled it up in vim, but the syntax highlighting didn't expose anything for me. ~~~ Tobu It is. Though it only works well if you use it like this: ./hou ansi.txt hou.c ------ ewanmcteagle Seems to be the same John Tromp of the Computer Go bet. <http://dcook.org/gobet/> ~~~ Evbn Wow, John accurately predicted the year computer Go would beat him, 15 years in advance, and made a $1000 by being slightly conservative. Nice long bet! ------ venomsnake Amazing entries. These are also the winners for "language you currently hate" clear code contest. ------ customary I must admit I was disappointed in last year's contest winners, namely their general focus. I thought maybe something had been lost in the years the contest was not running. But these entries are great! Binary lambda calculus? Top notch. IOCCC is back! Check this out { echo one;echo two;echo tres;}|./kang result: the sum in hex
