Dynamic Programming – Live Sessions  Refdash - <AUTHOR> https://refdash.com/sessions <comment><AUTHOR> Refdash is developing the most engineer friendly way to apply to companies. A big part of that is doing well in interviews. We personally interviewed thousands of engineers at Refdash, and noticed how even the best engineers were stymied by trick questions. This led to the creation of Live Interview Sessions, aimed at helping engineers excel at interviews.

The Rhino's Last Stand - <AUTHOR> https://www.guernicamag.com/features/the-rhinos-last-stand <comment><USER2> Open trade in rhino horn? The only market-based approach I'd tolerate would be the development and flooding of the market with an indistinguishable synthetic horn designed to trigger impotence in all the idiots who buy it.

The answer isn't in economics. It isn't even in protecting rhinos. The answer is to educate all the stupid men of the world that still believe that eating something shaped like a penis will increase their virility. That myth is the real issue. I really don't care whether such things are part of any culture or belief system. You don't get to wipe out such a species because you cannot bother to exercise enough to keep it up on your own.

<comment><USER3> Rhinoceros horn is not used as an aphrodisiac, rather to treat fevers. (of course it doesn't actually treat fevers either) That aside, there are quite a few people who have misconceptions about medicine; it seems noble but very difficult to correct them all.

Why do you oppose market-based solutions? If any solution prevented some large percent of poaching incidents, would it not be a net improvement?

<comment><USER2> > If any solution prevented some large percent of poaching incidents, would it > not be a net improvement?

Perhaps for the Rhino, a single species, but this isn't just about them. Tigers, bears, lions, elephants ... nearly everything bigger and more powerful than humans gets chopped up for "traditional medicine". We cannot start farming each and every critter some group thinks is magic.

Market-based approaches are also an acknowledgment of the underlying mythology. I'm generally opposed to all quack medicine. Most of us are annoyed but not screaming mad when we see homeopathic junk for sale a drugstores. We laugh, try to educate our friends, and perhaps sign a petition to ban such practices. But if I see baby rhino horns for sale at WholeFoods expect blood.

</comment></comment></comment><comment><USER4> > Proponents argue that an open trade would flood the market and deflate the > bubble—the street value of horn currently stands at $100,000 a kilogram, > more than that of cocaine—driving down the incentive to poach.

It would not decrease the value enough to make poaching not profitable for the poachers. Proposals like this one are very frequent but none of them address the issue of how exactly are the animals living in the wild protected against poaching. The assumption seems to be that as long as there are ranchers raising these animals for profit, the species should be protected. It does not address the issue of what will happen to the species once the demand for rhino horn plummets.

These legalized sales are very unpredictable. For example, the current ivory poaching crisis is attributed to the 2008 CITES reclassification of ivory that let some African countries sell their ivory stockpiles to China and Japan. This event caused an increase in demand for ivory products in China and Japan and the demand for ivory has been increasing year over year since then. As a result, poaching has skyrocketed to meet the demand.

If you live in Washington state, please support Initiative 1401 ([http://saveanimalsfacingextinction.org](http://saveanimalsfacingextinction.org)) on the November state ballot. This initiative will help with reducing the amount of illegal wildlife products coming to the US. Most of these products come to the US from China so ports in Washington state are a prime destination for the ships smuggling these products. California has recently passed a similar law.

I've recently started volunteering with the campaign and we are looking for more volunteers who would help out with the campaign efforts. If you live in Washington state and have 2 hours of free time every now and then and want to help out, email me at adamnemecek at gmail.com.

<comment><USER5> I suspect that these proposals are partly due to desperation. Nothing else seems to be working; At least if we're farming them there's an incentive to keep enough alive that they won't go extinct.

<comment><USER4> The thing though is that these proposals usually come from groups that are not exactly impartial. These include e.g. Safari Clubs, "anti-environmentalist think tanks", ranchers and other groups who would gain from free trade of wildlife products.

> Nothing else seems to be working;

That's the thing though, not much has been tried as far as bans go. The current bans leave a lot of loopholes so getting around the restrictions isn't exactly hard.

</comment></comment></comment><comment><USER6> It might work if their were an appreciable increase in the African standard of living as well. As it is, the price of horn could be $100 per kg and there would still be someone poor enough to poach. However, it would at least reduce the drive to poach substantially, and that may be enough for the Rhino to survive.

On the other hand, we may have to face the fact that in the modern world large wild animals simply aren't going to survive. It seems sad, of course, but there is really nothing super-natural about it. Many more species have gone extinct naturally than currently roam the earth. Perhaps it is for the best. There is a reason we humans left the trees and created civilization. Surviving in the wild is hard. The larger (and generally smarter) animals have some awareness of this and probably, if given a choice, would choose a "civilized" existence as well. If we make the effort to make zoos very accommodating to the needs of animals (which means putting a lot more money into them) then I think that is the future --and a generally better one for all.

<comment><USER7> I wouldn't be surprised if the African poachers were already making around $100 per kg; a lot of that money goes to the cartels (and government officials who have been bribed to look the other way).

<comment><USER4> It's a lot less than that actually, it's on the order of hundreds of dollar per tusk (a male elephant's tusk weight ~50+kg). And you are right, the people who are making money from this are up to no good, a lot of these groups are militias and terrorist organizations. There was a recent article about this in National Geographic

Here for Android beta - <AUTHOR> http://here.com/beta/android/

<comment><USER2> Strange this is an APK download, requiring users to reduce their security settings and download+install manually. A better way since mid-2013 is to make use of Android's alpha/beta/staged rollout setup. Ratings of beta users don't count towards the official rating if that's what they're worried about.

[https://support.google.com/googleplay/android- developer/answ...](https://support.google.com/googleplay/android- developer/answer/3131213?hl=en)

<comment><USER3> > reduce their security settings

I don't get how enabling side-loading is "reducing" security. Regardless of whether an APK comes from the play store or not the system still presents you with the permissions dialog and the apps still run sandboxed.

<comment><USER4> Permitting the installation of apps from untrusted sources is a big security risk, because it facilitates drive-by install attacks. Once you've ticked that box, Android doesn't subsequently warn you that you're installing an app from an untrusted source. Malware is disguised as a system app and installation is deferred until something else updates, so even savvy users can be tricked into allowing the installation of malware.

<comment><USER5> You could just untick the box after you installed the app though.

</comment></comment></comment></comment><comment><USER6> HERE is the new(ish) name of NAVTEQ, before Nokia purchased them. They've been in the map business for a while.

[http://en.wikipedia.org/wiki/Navteq](http://en.wikipedia.org/wiki/Navteq)

</comment><comment><USER7> OpenStreetMap has such a level of detail (at least in Europe) that I can completely relay on it for my trips. I went on a drive from Italy to Holland a month ago using MapFactor Navigatior with OpenStreetMap maps, and I was really surprised how good it worked. It even had POIs for the toilets on the highway! Amsterdam was mapped really well as well, with house numbers and everything.

And it was completely offline (even the routing algorithm) and free.

<comment><USER8> It's just a pity the apps aren't quite there on Android. I find MapFactor Navigator to be clunky and outright confusing, Telenav Scout is only available in the US, Skobbler seems to have been withdrawn (at least, it's not accessible in the UK Play Store), and OSMAnd is great for what it is, but has no traffic information, and is a bit guileless in selecting a route - certainly enough so it's not sensible to trust it for long journeys.

<comment><USER9> Skobbler has been acquired by Telenav and they have been releasing updates to their apps. I'm surprised you're saying they have been withdrawn, as I got this app on all of my Androids: [https://play.google.com/store/apps/details?id=com.skobbler.f...](https://play.google.com/store/apps/details?id=com.skobbler.forevermapng)

I personally love it - it's cheap, it's polished and it works.

<comment><USER8> Yes, I was hoping to use that app- I can see that in the US webstore, but nothing comes up searching for it on my UK phone.

Maybe they're half-way in transitioning from Skobbler to Scout, and they've removed the former without adding the latter. But I'm pretty certain it's been like this for weeks if not months, because I've looked unsuccessfully before.

<comment><USER9> I'm from Romania, so it isn't just in the US. Maybe the app has problems in the UK that need to be fixed, as your zip codes are nonnumerical and you're driving on the wrong side of the road :-)

They had an update in September, so it's alive. You could contact them at firstname.lastname@example.com … BTW, I care about them because the company may have been German but the developers were Romanians :)

</comment></comment></comment></comment></comment><comment><USER10> I've used HERE on FirefoxOS and was impressed for a HTML5 application working relatively well on an under powered smartish phone.

Majority of the work the HERE guys do is behind the scenes magic for car manufactures, they are just attempting to crack the consumer market.

I met a couple of the HERE guys in Berlin, they seem quite humble and want to play a bigger part in the mapping community whilst keeping existing clients happy.

Also to note, OsmAnd is awesome and have just traveled eastern and western Europe extensively with it.

</comment><comment><USER11> Nice! 4,970 MB to download the entire map of the USA for offline use, or you can just download individual states. Unlike Google maps, there's full offline routing and search as well.

The transit overlay for pedestrians looks great with realtime tables for the stops.

</comment><comment><USER12> Interesting move. HERE Drive+ on Windows Phone is better than any Android alternative as a navigation system. It just works and has a seamless offline experience. It is (used to be?) one of the main reasons to own a Windows phone.

</comment><comment><USER13> Here originally was the branding for the Nokia suite of Navigation Apps on Windows Phone. I've been using them on and off for probably three years now and have used the mapping app in the US and Europe and find it quite useful. Downloaded maps and offline navigation is a great feature when traveling internationally.

I just wish it would find its way over to iOS.

</comment><comment><USER14> finally!... I bought a 60 euro, 4 inch android smartphone without a data plan on it, and I already tried to download a OSM export to just browse it on my computer, without any luck. I thought I could export tiles and browse them as a html file on my phone, but I did not manage to do it.

On google map on the nexus 7 I managed to select a portion of an area and download it, but I could do it again on my huawei Y330. I could not make it work offline.

<comment><USER15> > tried to download a OSM export

> export tiles and browse them as a html file

Huh no you're thinking way too difficult, just download the OsmAnd app. I'm afraid it needs a few gigabytes of storage though, at least in Europe the map is very detailed.

<comment><USER14> even for a single city ?

<comment><USER15> They offer regions as default downloads, but it's all open source and open data, so if you want you can export a single city and use it in the app. It is quite a bit more work than just downloading regions (or small-ish countries like the Netherlands) though. See OsmAndMapCreator if you want to do this for the OsmAnd app.

</comment></comment></comment></comment><comment><USER16> Why does this need read permission for my contacts?

<comment><USER17> Because of the Glympse integration, I suppose.

<comment><USER16> Ah, I see. I hope it won't crash with my Privacy Guard blocking contacts. Offline maps is a win!

<comment><USER15> > Offline maps is a win!

If you care about privacy and offline maps, OsmAnd is the way to go. Open source software and offline maps.

</comment></comment></comment></comment><comment><USER18> What if Google does it? (reference to [http://wigdi.aws.af.cm/](http://wigdi.aws.af.cm/) )

<comment><USER19> In this case Google Maps has been steadily getting worse, so no worries. It feels like every month they remove features and make things take more clicks or require mystery meat navigation. It took me 15 minutes the other day to figure out how to get the list of directions back in navigation mode. You have to tap some unlabeled header. I'm sure that feature is headed for the cutting room floor eventually too even though personally I have no use for step by step navigation and just need to see the list of turns and I'm fine.

<comment><USER20> > In this case Google Maps has been steadily getting worse, so no worries.

Whether the UI changes are worse is a subjective claim, but the data Google has has not gotten worse. I've found all the alternative mapping solutions (Here, Bing, OpenStreet, and Apple maps) to be inferior when it comes to data quality which is the more important factor, unless you think getting directed through non-existing streets is a small concern. I'm not a Google fan, I've given up a lot of Google, but I can't quit maps or google search, although I use ddg quite a bit. Google has the most reliable map data, there is no competition and no good alternative.

<comment><USER21> The UI definitely got worse.

About two weeks ago I was unable to switch to Street View in the android app. It simply wasn't accessible through dropping the pin, as it was in the past.

When Google's flagship app on their own platform forces me to find computer and use the web version, something is seriously wrong.

<comment><USER20> > About two weeks ago I was unable to switch to Street View in the android > app. It simply wasn't accessible through dropping the pin, as it was in the > past.

The first thing you should have seen after updating and adding an address is a message telling you to pull up to get more detail. It took me 2 seconds to figure out how to get street view in the new UI. So as I said subjective.

<comment><USER21> One week ago, it worked.

Two weeks ago, it didn't. I even googled it, how I'm supposed to find it. The street view strip just wasn't there.

It's unpredictable. Nothing subjective, just seek-and-hide UI, which was always hallmark of bad UI.

</comment></comment></comment></comment></comment></comment><comment><USER22> Well, I can't seem to download this from my Android because it keeps wanting to use the web app instead. So much for that..

</comment></comment><comment><USER23> Why not use built-in Android TTS functionality?

<comment><USER24> Personally, I find the Nokia TTS much better (UK English, if that makes a difference).

</comment></comment><comment><USER25> free offline maps on android! This takes away one of the big unique things Windows Phone had going for it.

<comment><USER26> There are plenty of free offline maps on Android. This is just Here arriving late to a party started by OpenStreetMap.

<comment><USER27> I have tried many of them (the most popular ones at least), and I found HERE to be way better -- not because of the map data itself, but the look and feel of the app and also the quality of navigation is better than the rest (imho).

I tend to use it instead of Google Maps as well.

Re. Windows Phone: I think that if a cross-platform service gains foothold (on Android) then it's good for WP. If GMaps is the de facto mapping solution (as it is more or less), then GMaps not being present on WP is a deterring factor.

<comment><USER9> For a polished app that uses OpenStreetMaps, check out this one: [https://play.google.com/store/apps/details?id=com.skobbler.f...](https://play.google.com/store/apps/details?id=com.skobbler.forevermapng)

</comment><comment><USER29> Why does this require me to sign up with my name and date of birth to use the offline functionality?

<comment><USER30> I wondered that too, and then I deleted the app (Moto E with small internal storage). I'll still try the final version, but this is a turn off.</comment></comment>


Ask HN: How do you find good designers for your projects? - <AUTHOR>

I'm wondering what techniques you've used to find good designers for your projects.
I've tried Craigslist, but ended up with a lot of spam and a lot of ... let's say not very experienced designers.
I've tried various well known designers, but the costs very quickly become very high.
I've tried oDesk with some limited success - much better than the local craigslist crowd - but nothing I was thrilled with.
Is there a way to find reasonably priced designers who are actually good? What's the secret? <comment><USER2> I simply tried here and got lucky twice already.

Simply post a 'Looking for a designer' with some basic requirements (job duration, an idea of the scope and your location preferences) and ask for portfolio links.

That'll get you plenty of response.

Make sure you put an email address in the text area of your profile!

One of the issues some people run in to when looking for designers and programmers is that they want to scrape the bottom of the barrel pricewise, but that is going to get you in to a very long period where you'll be looking at stuff that doesn't cut it.

In that case I'd suggest moving 'upmarket' a bit and spend what it's really worth. If you ever get lucky and find that $10 per hour designer or programmer that delivers stellar work let me know.

One that I have no personal experience with but that has a really nice portfolio lives here: <http://www.gursimran.com/> , I've spent half a day just looking through her website and flickr album, quite amazing.

\--

edited for clarity.

<comment><AUTHOR> I'm willing to pay much more than $10 per hour, so long as I find someone good. Maybe I'll try posting here, that's an interesting idea.

<comment><USER2> I'm sorry, I did not mean to suggest that would be applicable to you.

</comment></comment></comment><comment><USER3> You haven't mentioned any of the crowd-sourced design sites:

<http://99designs.com> <http://crowdspring.com>

<comment><AUTHOR> Haven't tried any crow-sourced sites. I have some sort odd of mental block when it comes to these; I should get over it and give it a try.

</comment></comment><comment><USER4> I know crowdsourced design gets a lot of flack around here, but take a look at crowdspring.com or 99designs.com

I used to work at CS (as a dev), so I got to see a lot of entries.

You can get some good work for way less than an independent designer would charge. Some buyers ended up establishing relationships with designers they liked, too.

</comment><comment><USER5> If you just need design (little "d"), it would be hard to recommend anything other than 99designs.com, since you can get dozens of people to do the design work you need on spec, at effectively no cost to you, then pick the best (or none at all).

If you need Design (big "D"), then you get what you pay for, and you should be going with established, known quantities like an identity/brand specialized design agency. They do cost a lot of money, but that's because Design (big "d") is very hard.

The difference is that Design (big "D") is about strategy and communication, whereas design (little "d") is about drawing and coloring. Sometimes you need one, sometimes you need the other, and sometimes you need both.

<comment><AUTHOR> I'm looking for little "d", but with good drawing and coloring. Haven't tried 99designs, that might be a good way to go. Ideally I'd like to have a long term relationship so we can keep going back to the same person as new needs arise.

<comment><USER5> What I did was set up a logo contest for $400, then personally messaged 30-40 designers whose portfolios I liked on the site to ask them to participate. Once I saw enough good stuff, I guaranteed the contest (meaning I would definitely pick a winner), and asked people for modifications. That part is key; you want to find out not just which piece of design you like, but who is a good person to work with.

Moving forward, I actually ended up working with the person who won the contest AND another person who was very good, but just happened to be the wrong person for this particular design. Once they've done good work for you through 99designs, there is no reason you can't work directly together on future projects. I suspect that's part of the reason designers use the site (although many of them are also from countries where the dollar is highly valuable).

<comment><AUTHOR> Out of curiosity, where the designers US based or abroad somewhere?

<comment><USER5> Croatia

</comment></comment></comment></comment></comment><comment><USER6> I look at universities for design students (graduated). I had general good experiences with that way. Another possibility might be to look in eastern europe for offshore design agencies.

<comment><AUTHOR> Years ago we connected with an undergrad, paid him well, and he did fantastic work for us. When he graduated we put in several recommendations for him and he ended up doing well. Would love to get into the same situation, but I haven't had much luck finding another student.

</comment></comment><comment><USER7> I am in the same bind. I am wondering what a decent rate for a good design is. I need to design two simple pages ("simple" may be subjective.) I have been quoted $400 - just for design - by htmlburger (they seem good). Would you consider that too pricey?

<comment><USER8> No, that's not pricey. Consider all the elements that would need to be created to make even one page. Once you have elements in place, you can reuse them on other pages. So the first page has a bigger cost for the designer.

</comment></comment><comment><USER8> What job do you want done?

<comment><AUTHOR> Redesign of our homepage and a few informational pages, which should be fairly straight-forward design work, and design of the product interior pages as well, which will require more thought on usability, layout, etc.

<comment><USER8> Sounds like a whole project, running something around 50-75 hours or so. At a hourly rate of $50, I'd say that would be somewhere around $3000-3500.</comment></comment></comment>


Using neural networks to solve advanced mathematics equations - <AUTHOR> https://ai.facebook.com/blog/using-neural-networks-to-solve-advanced-mathematics-equations/ <comment><USER2> Previous discussion: [https://news.ycombinator.com/item?id=21084748](https://news.ycombinator.com/item?id=21084748)

I think the point in the comments about Mathematica et al just being more careful about the domain is pretty damning of the claim the neural net beats them.

</comment><comment><USER3> The potentially interesting thing here, to me, is using networks to short- circuit searches that could grow explosively with expression size, but then filter down to answers that can be shown correct. That's also a way to get some value out of a system that doesn't always produce the correct answer as its first guess.

In some cases it may be easy to prove the correctness once you have the proposed answer, but in others the network might need to produce intermediate steps or some kind of 'argument' to let the CAS check correctness in reasonable time. Perhaps do that by instrumenting a CAS to output intermediate steps and train the network on _that_ , not just problem/answer pairs.

Broadly, _humans_ who have seen a lot of problems solved can say "this looks like a situation where you could try X" and do X without going down all the blind alleys that a CAS might. So it doesn't seem implausible that _automated_ learned models might _also_ outperform the heuristics CASes have hard-coded in for making those kinds of guesses.

(You can imagine closer coupling, e.g. a CAS that calls out to an NN to propose solutions to certain hard-to-solve-but-easy-to-check subproblems, or uses learned models to try to guess the right branch to go down in a solution process that already looks like searching a tree of possibilities. But the more you have to crack open the CAS, the less appealing the whole thing becomes.)

<comment><USER4> I wonder how much of this intuition can be formalized, if, say, the number of deduction steps from a theorem to another can be _provably_ reliably approximated before attempting its proof.

Elon Musk's Tesla Roadster mounted on Falcon Heavy Payload Adapter - <AUTHOR> https://i.imgur.com/A4YSU6R.png <comment> shaki-dora As always, Matt Levine said it best:

 _I 'm not sure I agree that he "isn't joking": Just because you actually do it, that doesn't mean it's not a joke. (Perhaps it's a "prank.") If you are rich enough, you can joke about sending a car in a rocket to Mars by actually sending a car in a rocket to Mars, which makes it funnier._

([https://www.bloomberg.com/view/articles/2017-12-04/bank- back...](https://www.bloomberg.com/view/articles/2017-12-04/bank-backups-and- space-bitcoins))

<comment><USER2> It's too bad he can't joke about sending a scientific probe to Mars and then doing it.

<comment><USER3> The point is that first launch has no serious interest to warrant a real payload due to the higher risk of failure. If they weren't doing something fun like this they would just be loading it up with dead weight.

<comment><USER4> Is't that machine worth six figures? Has the world gone mad that we can't find a more productive way to have "fun"

<comment><USER5> You are missing the point. The point he is making is that he is actually taken some risk or putting something that is dear to him, in jeopardy.

<comment><USER6> If the mission is successful, do they recover the car? Or will it be released into orbit? And if that, will it eventually burn up?

<comment><AUTHOR> It will orbit the sun for hundreds of millions of years

<comment><USER7> ... Until it is recovered by space pirates and sold as a historic artifact....

</comment></comment></comment></comment></comment></comment></comment></comment><comment><USER8> That thing inside Elon, that thing that whispered in his ear and pulled at his heart that drove him to build Tesla, SpaceX; those same exact neurons, or that karmic energy, or spirit, or demon; that insatiable lust and yearning, the ego and hubris to believe it could all even be possible; the fuck-all attitude which gave him the courage to try...

[The Greeks called it "Ate" (pronounced ay-tee) ~ the point between Hubris and Nemesis.]

The swirling vortex which is Elon had no choice but to strap his black cherry red Roadster onto the biggest rocket we've seen in a generation, and on its inaugural flight, send it to fucking Mars.

God speed Elon.

<comment><USER9> This is a juvenile BS move that will infest another planet...one that humans have never walked on...with this rich kids car.

With a rich kids car.

Scalable Stream Processing: A Survey of Storm, Samza, Spark and Flink - <AUTHOR> http://medium.com/baqend-blog/real-time-stream-processors-a-survey-and-decision-guidance-6d248f692056#.b1n6hnbrd <comment><USER2> What about using Apache Beam[0] for an abstracting over these stream processing frameworks? In a recent Software Engineering Daily podcast[1], Frances Perry recommends using Flink for the data flow model.

1: [http://softwareengineeringdaily.com/2016/08/19/apache- beam-w...](http://softwareengineeringdaily.com/2016/08/19/apache-beam-with- frances-perry/)

<comment><USER3> The problem with Beam is that it is an abstraction layer.

This sounds like a stupid comment, but when the underlying services are all evolving as quickly as they do in this space programming against an abstraction layer means you need to wait for (often sorely needed) new features.

(Frances Perry is an engineer on Beam at Google, so it would be surprising if she recommended against it)

<comment><USER4> Do you have examples of such features? Most production deployments of these kinds of things don't upgrade THAT often.

You have a point that abstraction layers can limit you since it's another compatibility layer, but looking at what's done in actual practice I don't see it being that bad.

If anything, it should be evaluated on a case by case basis.

Flink is actually better tech overall for my use case, but a lot of customers want spark streaming since it's already installed. Having beam where we can do both is kinda nice.

<comment><USER3> We had to abandon Cloudera (and Horton Works) Hadoop distributions because they didn't ship R support for Spark quickly enough (in 1.3 or 1.2 or whatever version that was).

We jumped from 1.5 to 1.6 because of algorithms in MLLib (although that turned out to be a bit of a disappointment).

<comment><USER4> Most organizations I see tend to just wait...this sounds more like 1 off to me. You're at a unique employer if the data scientists have that much power..

</comment></comment></comment></comment></comment><comment><USER5> Great article, although it would be nice to also add the cost (price) of running the systems. For instance, on our own custom solution we were able on 1 small machine to save 100M+ records (about 100GB) a day for $10 total (processing cost, disk cost, and backup cost). Which is why I'm curious how it compares. See [https://www.youtube.com/watch?v=sG5qtN8E-6Q](https://www.youtube.com/watch?v=sG5qtN8E-6Q) and [https://www.youtube.com/watch?v=x_WqBuEA7s8](https://www.youtube.com/watch?v=x_WqBuEA7s8) .

</comment><comment><USER6> I work on IBM Streams, which was discussed and dismissed. The author is correct that we need to have more public benchmarks. I think our system should be in the upper right of the high-level view, but of course I would think that, as someone who works on it.

Something I can point to is a modified Linear Road benchmark: [https://github.com/IBMStreams/benchmarks/tree/master/Streams...](https://github.com/IBMStreams/benchmarks/tree/master/StreamsLinearRoadBenchmark)

This benchmark was made at the request of a potential customer. Our implementation scaled to 200 "lanes." The other systems tested did not scale past 50. Unfortunately, that's as much as I feel I can say until I speak with some of the people involved in the comparison.

Something like spark or kafka streaming but that doesn't depend on hundreds of megabytes of java stuffs?

I just want to do basic windowing/counting against data streams.. I don't want to be part of a gigantic java ecosystem :-(

<comment><USER9> Depending on your requirements, a single-node solution like PipelineDB may suffice; it's a PostgreSQL extension that lets you write streaming SQL queries.

<comment><USER10> PipelineDB can scale out to multiple nodes (for $).

<comment><USER9> Is there a reference regarding the number of nodes that can be deployed in the cluster, and are feasible to maintain? From the docs, I gather that "[a]ll DDL/non-stream DML statements are executed in a distributed transaction on all nodes in the cluster and committed via two-phase commit." [1]

Doesn't that get in the way of low latency and availability?

Ask HN: Does anyone know the technology behind Magic? - <AUTHOR>

What platform do they use for two way text messaging? How do they do payments? <comment><USER2> They use a custom-made system for payments based on Stripe. I was working on a SaaS product where you could generate unique links either manually or via API for taking payments for SMS-based systems.

Drop me an email (it's in my profile) if you'd be interested in that and tell me what you would pay a month

<comment><AUTHOR> Can you email me? Our idea is, hire a local "expert" to build your itinerary when you are visiting that local's town/city. Someone posted it on HN and we wanted to run with it.

Ask HN: Are there any segmented HackerNews? - <AUTHOR>

Do you know whether there are any segmented HackerNews? The articles should be from HN or synchronized with HN but with segmented by countries such as US/UK/etc or targeted markets? So it will let people know more about that segmentation. <comment><USER2> There was a try for a HN-like specific to Europe news, hackful.eu but it is not really active

<comment><AUTHOR> Thanks for the information!

Yeah, activity is the problem if do a HN-like site because the community of HN is great and can't be copied. So I wonder whether there are any sites which segment the articles in HN. And also it can be the window to show the community what happened in that segment(country).

BTW, for HN-like specific to China, tea.tisiwi.com is another experiment.</comment></comment>

Pay for your own dog food - <AUTHOR> http://blog.inklingmarkets.com/2009/10/pay-for-your-own-dog-food.html

<comment><USER2> Good idea. The pricing structure is part of the product. I did the halfway version of this in a previous project: there was a special magic credit card number which didn't actually get charged, but I got the emails every month telling me what had been fake-charged so I felt that part of the customer experience. Recommended.

</comment><comment><USER3> People have wildly different notions about what they consider a reasonable price for something. Before I started making social apps, I was selling import books. I had people often paying $50 or more for something that in Japan might have cost $5. Definitely would have missed that if I had just tried to imagine what I would be willing to pay myself, only way I discovered the "real price" was by auctioning items first.

</comment><comment><USER4> It's also a good sanity check on your payments process -- if you don't get charged, or you get charged too much, you'll know about it a lot sooner than if you waited for customer complaints to roll in.

</comment><comment><USER5> Idea works well for subscription type payments. I don't know if it works that well for one-time software sales, though.

I'm making a mac application. Most likely I will be charging $50 for this application. It looks like my current design budget is about $1,500. I feel that if I find the product worth $1,500 someone might be willing to pay $50.

</comment><comment><USER6> Doesn't seem like that would work if, say, I'm a startup trying to sell high- volume VoIP service to large enterprises.

<comment><USER7> Agreed. It really depends on your market/product. Though I will say that finding a way to use your product (even if it is simply using your VoIP service at low-volume) will unearth the bugs you might otherwise be missing (but that your clients are definitely not).

</comment></comment><comment><USER8> It may be better to "pay" for your application by taking that money out of the organization by donating, "losing", or burning it.

Only when the money actually disappears will you be able to have a good feeling for how the price affects decision making.

edit: I think it would be better to burn the money than donate it to eliminate the positive reinforcement donating would provide.

</comment><comment><USER9> This is essentially how I set the pricing for Tarsnap -- I started out by asking myself "how much would I like to pay to store my backups?"

<comment><USER10> Nearly everyone does that, the problem is often that they're not entirely honest with themselves. I know I've caught myself (and others) doing this:

Bob: "I'd totally pay $20/month right now for X"

Sally: "Your lucky day! Xyz.com has exactly that and it's only $15/mo!"

Bob: "Oh, um, uh, well I don't _really_ need it that bad _right now_ "

Actually taking out your personal credit card can be an enlightening experience.

</comment></comment><comment><USER13> Not doing this is one of the biggest problems with Microsoft's internal dogfooding efforts, in my opinion. They dogfood just about every feature of every product MS offers, but the one thing they never, ever dogfood is licensing and pricing. Everyone just installs "Windows X Ultimate" or "Windows Server X Enterprise Edition" or "Visual Studio X Team System" or "SQL Server X Enterprise" as many times on as many machines supporting as many users as they feel like, rather than being pressured by budgetary constraints to pick the product that meets their needs best at a price they can afford.

The result is that most of the MS rank and file remain blithely ignorant of the extremely high retail prices of these products and their convoluted (sometimes almost punitive) licensing schemes. Given that licensing and pricing is a critical aspect of software use and can easily make the difference between user satisfaction and user desertion to a competitor's product, I've always felt this oversight hurt Microsoft far more than they imagine.

<comment><USER14> When I worked there a few years back, the developer tools team was begging for any feedback. The rest of the company would install Visual Studio Glacial Epic Edition and maybe fire it up to edit the odd dialog template, but did as much work as they could in vim or emacs and sometimes windbg (a much more powerful standalone debugger from the same team). Even if you wanted to use it, you were on your own getting it to compile your code, because the build system everyone else used (a make clone with specific support for win32 binaries) didn't interop at all with Visual Studio project files.</comment></comment>


Fixing the Ph.D.  - <AUTHOR> http://newyorker.com/online/blogs/joshuarothman/2014/06/fixing-the-phd.html

<comment><USER3> This article wrongly implies that people getting English PhDs are only doing so in order to become tenure-track English professors. But I just completed my PhD in English two weeks ago, and I'm also the TECH co-founder of a VC-backed startup. Many of my peers are not just tech savvy, they're also developers, designers, and entrepreneurs. They just also happen to be interested in studying slightly older forms of technology -- literary technologies.

Yes... books and poems and epics and dramas are all technologies, too.

I should hope the HN community isn't fooled by the _New Yorker_ article's professional typecasting. After all, Paul Graham has an entire book called _Hackers and Painters_, and he argues: "Of all the different types of people I've known, hackers and painters are among the most alike. What hackers and painters have in common is that they're both makers. Along with composers, architects, and writers, what hackers and painters are trying to do is make good things." ([http://www.paulgraham.com/hp.html](http://www.paulgraham.com/hp.html)).

"Hacking" \-- as both Paul Graham and much of my dissertation argues -- isn't a purely scientific discipline. It's also a humanist and aesthetic pursuit.

If you don't believe me, go pick up a collection of Emily Dickinson poems (you know... the things you probably haven't looked at since you were in 9th grade). You might be surprised to discover all of the conditional logic, the programatic loops, and the object oriented structures.

Impressive. However, judging from the available empirical evidence from recent professional surveys [1], you and your like-minded peers are indeed the _exception_ , not the rule: over the last 35 years, a consistent 90-95% of newly-minted English PhDs sought academic faculty positions; with only 5-10% seeking careers outside academia [Fig. 2]. There is a reason why the so-called ' _alt-ac_ ' career track is called that way in the broader MLA community.

[1] [http://mlaresearch.commons.mla.org/2014/02/26/our-phd- employ...](http://mlaresearch.commons.mla.org/2014/02/26/our-phd-employment- problem/)

</comment></comment><comment><USER5> Fixing the _English_ Ph.D; that's the only field they mention. They can make inferences about related fields but would have a hard time with other fields (STEM fields and even psychology).

<comment><USER6> "The M.L.A. report estimates that only sixty per cent of newly-minted Ph.D.s will find tenure-track jobs after graduation"

It's even worse for sciences.

But I think there are some insights in common; worth a read.

<comment><USER7> Once you get your doctorate, the logical step for most STEM graduates is a postdoctoral position. There aren't many of these at all, most departments have double the number of PhD students than they do postdocs. So right off the bat, half the students will be finding jobs elsewhere. Industry (hardware/software/analytics/whatever) pays more, is often more fulfilling and although your work isn't completely open it is usually more obviously relevant than your PhD.

So 60% will find tenure track jobs? Well that's obviously true. If there are only about half the postdoc positions compared to the number of new PhDs then only half the PhD students will be getting tenure track jobs.

Most postdoc positions are 2-3 years and are filled by newly minted PhDs. The logical evolution for most people is to do a postdoc (or two) and wait until their research is renowned enough for the university to offer a lectureship. You do that for another few years until they offer you a Readership, wait a bit longer and you get your coveted Professorship. If you're really lucky and you're top of your field you can hit assistant professor by 30-35 in the UK.

Until you get the all-important lectureship offer you're a contract worker and there is always the prospect that funding will be cut and you won't be able to renew your position. Remember that once you've done your postdoc there are even fewer positions to be promoted into.

Doing a PhD has largely put me off the idea of staying in academia, I think this is becoming more common. Being a professor would be nice, good pay (£60k min) lots of travel, but it's a very stressful job, you have no time to do any real research beyond project management and by that time you're thoroughly institutionalised.

Should point out that my experience is from physics, ymmv. On the plus side I don't know anyone who has struggled to find a job from my department; plenty go into research in non university groups like Microsoft, the British Antarctic Survey, the Met Office, etc.

<comment><USER8> > If you're really lucky and you're top of your field you can hit assistant > professor by 30-35 in the UK.

This role doesn't really exist on the UK, the equivalent is that of Lecturer/Senior Lecturer. I think you're overstating the barrier to entry -- it's not _that_ high unless you're fixed on a top university. In CS,I know lots of people younger than 35 with SL jobs. Getting to the level or prof after that is another matter but on the whole I think that should be hard.

</comment></comment></comment></comment><comment><USER9> From reading other articles and blogs on the problems with PhDs suggests that the situation is generally the same in other fields.

It is generally accepted that the PhD program is to train academic researchers. People who do both research and write papers, articles. Grants, etc are awarded on the basis of publishing accomplishments. Hence the "Publish or Perish" cry.

There is an oversupply of PhD graduates, so the academic job market is very competitive. Of course, in STEM, many PhDs find jobs in non-academic fields.

<comment><USER10> As someone who has earned a PhD I think the key thing is these programs are set up to train _researchers_, not specifically academic ones. As you say non- academic jobs in STEM are easy enough to find, and industrial research is alive and well.

</comment></comment><comment><USER11> It seems that the main issue is that people are only now discovering that PhDs and perhaps sometimes undergrad degrees in humanities are not vocational. This isn't to say they aren't worthwhile or that students shouldn't pursue them. There are plenty of degrees or experiences that are unlikely to be marketable in the future economy. The main thing students must learn is how to learn, and one can accomplish this by studying a variety of fields.

It does, however, mean that subsidizing higher education is a risky proposition. Universities go to great lengths to create humanities requirements perhaps in part motivated by a genuine belief that core requirements are necessary for a proper education, but likely also to beef up departments that have been isolated from market pressures. These departments are often political (almost always liberal), ideological, and rarely subject to any kind of quality control (there was the famous case of Larry Summers questioning what exactly Cornell West was doing as a tenured Harvard professor). Subsidizing learning with no direct market rewards can be a very smart long term investment in human capital. We need history and literature to have the cognitive tools to innovate and to articulate ideas necessary for the Western world to exist. But on the other hand, it's a dangerous proposition to create a mini-industry where you pay people without a clear understanding of what they are doing and why.

</comment><comment><USER12> It takes a while to get to the key point:

 _If anything, a continuing over-production of Ph.D.s will only make the problem worse. It creates an ever-growing pool of cheap labor, which administrators are only too happy to employ in place of tenure-track faculty._

Shortening Phd programs, and many other so-called solutions doesn't fix this. Blaming a lack of interest in writing doesn't fix it either.

In my mind, the #1 fix is to highlight with full transparency the lack of career options, so that potential Phds know what they're up against.

The second is to create a relevant drop-off point after 2 years. 2 years in a Physics Phd program is good enough to enable many other careers. 2 years in a Phd program in English should be enough to prepare the student to work in the news, writing or something similar.

The big issue here is optimal school behavior (produce as many Phds as possible) conflicts with optimal system behavior (produce roughly the amount as jobs). In the sciences, limits to funding helps provide some of the cap.

</comment><comment><USER13> In honesty, part of the problem with PhD 'grad school' in the US is that the prior parts of the pipeline - undergraduate and high school - are so poor. If you're spending a couple of years when people come to college teaching them, effectively remedial science, then of course it's going to set the whole thing back a number of years (manifesting itself, at least partly in this case, in it taking 10 years to complete a PhD in the US.) (Data source: the ten people or so I know who've worked in academia in the EU and the US - <USER2> conclusive, but compelling qualitative data when you consider the strength of their views.)

The other issue here is that, if you take into account the fact that most people studying a PhD in the UK will already have done a (taught) Masters level course, then there's a helpful process of elimination there as well. It seems much less of a pre-requisite in the US.

</comment><comment><USER14> Interesting that they are blaming the profs. There is certainly some culpability there. But there is plenty of info available to students about their prospects. If they want to take on massive debt to essentially be entertained for a few extra years, at some point, that is their choice.

<comment><USER15> It's not a always the case that people incur massive debt. A lot of students have scholarships that cover their fugitive fees and include a small stipend.

</comment></comment><comment><USER16> There is advice in business:

"fail, fail often, fail EARLY!"

Yes, the article is right in one thing: It can take you ten years (including undergraduate studies) to get a PhD. It takes you 10 years to find out if there is a market (not now but in 10 years) for you.

Don't get a PhD. Don't get a PhD in any field.

Scoop: A Glimpse Into the NYTimes CMS - <AUTHOR> http://open.blogs.nytimes.com/2014/06/17/scoop-a-glimpse-into-the-nytimes-cms/ <comment><USER2> Context: I'm a former copy editor with experience working for digital-only (e.g. Forbes.com) as well as print-driven magazines newspapers.

One of the things that's difficult when designing a CMS that works for both digital and print is that there are far fewer space constraints online than in print, and you want to ultimately generate an article that works in both formats. (Oh, and on mobile, and in a condensed version in a sister publication, and an expanded version for the wire.)

For hard news, the inverted pyramid format comes in handy -- if you don't have enough space in the print edition, you just lop off the last few paragraphs -- but for things like op/eds and magazine-style pieces, that doesn't always work.

What I'd love to see is a CMS (and, more fundamentally, a way of representing the underlying data) in which writers and editors can designate certain paragraphs or sentences or phrases as more important than others, so that even a story with a complex format can be dynamically "scaled," sort of like what web designers do with media queries, or what image editors do with seam carving.

<comment><USER3> > a way of representing the underlying data in which writers and editors can > designate certain paragraphs or sentences or phrases as more important than > others

Doesn't HTML do this?
 is more important than
, etc.

<comment><USER2>
Well, yes, but in only the broadest sense possible. For the purposes of an op-ed piece or a feature story, though, you'd need to have much more control.

Actually, this comment illustrates that such a system might not be as easy as you'd think. Some natural-language processing/generation would come in handy to ensure the following <num-of- bullets> things:

        * proper capitalization
        * subject/verb agreement
        * proper punctuation
        * number agreement

<comment><USER3> Aren't these the job of a human editor? (or is this the reason why my e-newspapers have so many copy editing errors?)

</comment></comment></comment></comment><comment><USER4> The CMS is in a renaissance period with Wordpress, Joomla, Drupal and the like falling out of favor.

I believe the CMS is bifurcating into two specialized directions.

Several online publishers are coming out and describing their new, home-grown custom CMS. The features are rich and provide robust, innovative tools across the long-form content lifecycle: writing, editing, and publication. There is special attention to collaboration.

On the other hand, more and more website developers align themselves with the goals and properties of static site generators. SSGs are best suited what I call "malleable" websites.

Thus, I think the way to think about this CMS renaissance is that traditional the CMS tried (and failed) to optimize for both long-form content and the malleable website. As a result, people are sick of trying to patch the traditional CMS with plugin after plugin and instead are simply crafting their own.

<comment><USER5> I would humbly suggest that static site generators are not nearly as popular as you might think if you only view the CMS market through the eyes of the HN crowd.

SSGs are hugely popular among nerds and practically unknown among everybody else. The result is a kind of distortion where, to nerds, it looks like SSGs are about to take over the world -- "all my friends use them!" But step outside that tight network of people and they are more or less completely off the radar.

<comment> chestnut-tree I agree - I find the idea of static site generators (SSGs) very appealing, but they are not user-friendly to setup - unless you happen to be technically- minded. Some tell-tale signs that SSGs are made by programmers for other programmers: command line-installation and configuration, a liking for markdown (and a dislike for WYSIWYG).

Just to be clear, I'm not knocking any of this. The fact that people have put their own time and effort into building SSGs and then generously open sourced them is pretty awesome.

In my view, the audience for SSGs, whether intentional or not, is mostly other programmers. What would it take to make an SSG appeal to a broader set of users?

<comment><AUTHOR> > What would it take to make an SSG appeal to a broader set of users?

I don't think the SSG, as they largely exist today, will ever gain widespread usage by mainstream users.

But one thing that _could_ drive greater adoption would be to develop an aesthetically pleasing web front-end that lets users write content using familiar WYSIWYG tools, but save the content to local files instead of a database. From there, the process would be largely the same as it is now: transform this directory of lightly marked up plain text files into raw HTML.

So, to answer your question: Make it more like Wordpress.

<comment><USER4> There is no doubt that SSGs will "grow up" and appear to gain features like Wordpress. The difference will be that SSGs are born out of loosely coupled tools in a toolchain ecosystem. Over time, I believe the successful SSGs will have a decidedly Unix flavor to them. Take [http://www.metalsmith.io/](http://www.metalsmith.io/) as an example.

<comment><USER6> SSGs are fundamentally flawed. The web is moving fast away from being a static page-centric medium to a dynamic content-centric one.

<comment> vertex-four I think the future of "SSGs" is that they're going to end up as programs running on the server that watch data from various feeds - databases, RSS feeds, APIs - and generate output from those. Basically, a streaming processor framework. The output would likely be in a "semi-baked" format so that they can contain processing instructions that are executed at request time, or otherwise lazily.

These won't be static site generators any more, and will lose out on the "you can throw it up on Github Pages" benefit, but they'll be far more powerful, and it'll be easier to develop dynamic, data-driven websites.

Seems like you could offload the editing, saving, tracking changes to google docs - a platform many people seem familiar with now - and then keep the actual CMS to a bare minimum. Have it import the text & spit out a static page even.

<comment><USER8> That is a very interesting idea, but since NYTimes opensourced their ICE editor, I am not sure what Google Docs would provide.

<comment><USER7> Transparent version control, tracking of changes, collaborative editing, familiar interface, familiar workflow (just drop finished articles into this directory to be available to the CMS)

<comment><USER11> No.

We use a pretty normal ("boring") Java stack with Spring, Hibernate and Jersey. Some of the older components use Struts + JSPs whereas the newer components use Backbone (and related libraries).

<comment><USER12> Which database? A JDBC one?

<comment><USER13> scoop uses mysql for its managed repository. we also use mongodb for our published repository that serves our apis to everybody else.

<comment><USER15> I know ICE is on it. That's just a VERY small part of the entire CMS, however. Why the downvotes?

<comment><USER17> I didn't downvote you, but vague comments idly questioning the point of the article usually don't do well on HN.

<comment><USER15> Oh, I should have written my post better.

It should be known that I love behind-the-scenes more than the movies, and I love these peeks more than anything else. Just was genuinely curious why NYTimes would take the time to show us. I don't think it would help any with the subscriptions/circulation numbers but I am probably wrong.

<comment><USER19> I don't, and it would be too expensive even at $15 imo. But even if something like this had a market there's the problem of the editor, as it uses contenteditable which is at best inconsistent across browser and at worst completely broken. That's also the reason Google Docs dropped it and started doing editing the hard way. As long as you know who uses your software and you can enforce the use of a given browser (as is the case with the writers for the NYT) there's no problem with contenteditable, but for a general solution you need to drop it.

Can this startup kill off the supermarket? - <AUTHOR> http://fortune.com/2014/08/04/can-this-startup-kill-off-the-supermarket/

<comment><USER2> I used FreshDirect frequently when I lived in New York. It's incredibly useful -- particularly if your only local supermarket is fairly awful for real food like produce or meat -- but it's also fantastically expensive. I don't see how Farmigo can skip FreshDirect's warehouse model of distribution without even more drastic cost premiums.

Grocery delivery IS the future of supermarkets, but it requires significant infrastructure to make it cost-efficient. As Amazon is the only real player in Silicon Valley to invest in delivery infrastructure, it seems pretty likely that this future belongs to Bezos.

Matthew Yglesias posited that groceries would be the next logical step to build out that final mile to customers. When AmazonFresh starts building out with muscle, that's when it's time to short FedEx and UPS.</comment>


Court grants Chevron access to 9 years of email data of activists, critics [pdf] - <AUTHOR> http://dg5vd3ocj3r4t.cloudfront.net/sites/default/files/documents/Kaplan-Order-Hotmail-IP-subpoena_0.pdf <comment><USER2> Welcome to the world of complex litigation, where cases take decades, span continents, and make lawyers eight figures.

[http://www.plainsite.org/tags/index.html?id=701&complex=1](http://www.plainsite.org/tags/index.html?id=701&complex=1)

This particular case docket can be found here:

[http://www.plainsite.org/flashlight/case.html?id=2322215](http://www.plainsite.org/flashlight/case.html?id=2322215)

Stanford Law had a one-day conference devoted to this case, and I heard top lawyers from both sides speak. I emerged disgusted by just about everyone. There are no winners in this matter--except the lawyers.

</comment><comment><USER3> If there is enough proof to grant them access to these records, why isn't a prosecutor taking over the case ? Giving access to confidential data to the adversarial party doesn't seem very wise.

<comment><USER4> The bar for discovery in a civil litigation is far lower than the bar for initiating a prosecution. And that's how it should be. If you are convinced that Enron dumped toxic waste in your town on purpose, should you have to prove your case to a point sufficient to initiate a prosecution before you're allowed access to their e-mails? That wouldn't make any sense--the point of discovery is to get all the potentially relevant facts on the table so they can be sorted through.

Also, setting the bar that high for discovery wouldn't make any sense. To initiate an arrest and criminal prosecution, you essentially have to have a "more likely than not he did it" belief in the suspect's guilt. But the "more likely than not" standard is all it takes to win a civil case. So by the time you get enough evidence to initiate a criminal case, you have enough to win a civil case.

<comment><USER3> Isn't there cases where the court would appointing a neutral party to do the search ? I understand that the plaintiff wants to get access to all these information but it seems unwise to allow them since they already are in a conflictual situation. It gives them power to discover other things unrelated to the case.

<comment><USER4> Chevron isn't getting direct access to a big e-mail database. Plaintiffs' lawyers will do the search and produce to Chevron only what's relevant, not privileged, not confidential, etc.

<comment><USER5> Chevron doesn't have council in house?

<comment><USER4> To be clear, I mean the counsel representing the activists will do the search and give only relevant documents to Chevron. Since the activists are adverse to Chevron, it wouldn't be appropriate for Chevron's counsel to go through the emails themselves.

<comment><USER12> Yeah really. Chevron is getting names and IP's for accused fraudsters/racketeers. Doesn't exact stir the same level of outrage as "the data of activists".

<comment><USER13> Wrong. Making a claim in a courtroom and telling truth has not got one thing to do with each other.

Chevron has the unmitigated gall here to claim the $18.2 Billion settlement against Chevron in Uruguay was the product of FRAUD. Chevron is claiming they did nothing wrong in Uruguay and they should be allowed to look look through 9 years of e-mail of activists to get the chance to try to dig up something up

</comment></comment><comment><USER16> Interesting, I wonder if this will lead to boycotts of Chevron? It does appear to be a pretty large human rights violation.

Show HN: CRUD Spreadsheets - <AUTHOR> http://www.hyperfiddle.net/:dustingetz!crud-spreadsheets/ <comment><USER2> Having a bit of trouble understanding what the potential solution is and what problem it solves. I may very well have missed it in There but figured I'd mention because others may have similar thoughts. So, what problem is this trying to solve?

<comment><USER3> Same for me. From what I understood you want to say that "people love spreadsheets" but "spreadsheets have limitations" (e.g. they have weak/no data schemas). If this understanding is correct then it would be helpful to see a practical example where said spreadsheet limitations become a problem and how your solution overcomes this problem.

The messy secret reality behind OpenAI - <AUTHOR> https://www.technologyreview.com/2020/02/17/844721/ai-openai-moonshot-elon-musk-sam-altman-greg-brockman-messy-secretive-reality/ <comment><USER2> An audio discussion of the contents of this article was front page HN back when this article came out: [https://news.ycombinator.com/item?id=22453211](https://news.ycombinator.com/item?id=22453211)

I'll go ahead and say what I said in that thread again re this article : "Person doing PhD in AI here (Ive seen all of OpenAI's research, been to their office couple times, know some people there) - tbh the piece was a pretty good summary of a lot of quite common somewhat negative takes on OpenAI within research community (such as that they largely do research based on scaling up known ideas, have at times hyped up their work beyond merit, changed their tune to be for profit which is weird given they want to work in the public interest, and that despite calling themselves OpenAI they publish and open source code much less frequently than most labs -- and with profit incentive they will likely publish and open source even less). The original article also presented the positive side (OpenAI is a pretty daring endeavor to try to get AGI by scaling up known techniques as they are, and people there do seem to have their heart in the right place) ."

</comment><comment><USER3> What I get from this article is that OpenAI is in many aspects similar to other research organizations, but with more resources and better PR. I think this article is reassuring for anyone doing AI research outside of the big labs. However, I also think that nothing that the article reports puts OpenAI in a particularly bad light; it's just the ordinary problems a research organization typically has.

(Note: GPT-2 communications were unfortunate and insincere, but I've witnessed similar, less high-profile communication blunders.)

</comment><comment><USER4> Recollections from past episodes of AI Hype Cycles. Soar was a massive project that spanned almost a decade and universities on multiple continents with dozens of researchers and significant funding from Darpa. See also Cyc.

 _" Soar is a cognitive architecture, originally created by John Laird, Allen Newell, and Paul Rosenbloom at Carnegie Mellon University.

The goal of the Soar project is to develop the fixed computational building blocks necessary for general intelligent agents – agents that can perform a wide range of tasks and encode, use, and learn all types of knowledge to realize the full range of cognitive capabilities found in humans, such as decision making, problem solving, planning, and natural language understanding. It is both a theory of what cognition is and a computational implementation of that theory. Since its beginnings in 1983 as John Laird's thesis, it has been widely used by AI researchers to create intelligent agents and cognitive models of different aspects of human behavior. The most current and comprehensive description of Soar is the 2012 book, The Soar Cognitive Architecture."_

</comment><comment><USER5> I read this when it came out and found it lame. It has the pretense of being an investigative hit piece, with all the length and gloss, but there's almost nothing to it. They come across as a bunch of painfully awkward geeks who are true believers and have been swimming in money. The reporter makes them look bad, you can make anybody look bad. I'm an AGI skeptic, but I thought she came out looking worse. A better or more experienced journalist would have dropped the story and moved on to something with some there there.

</comment><comment><USER6> As I've followed OpenAI, the recurring theme is that the subject/company goals opens messy politics and philosophies rather than focusing on the research. In some ways I can appreciate their retraction and controlling visibility so they can focus on the research. However, this only further exposes more politics and philosophical questions. They have to decide what "they want to be when they grow up" and filter out anything else that gets in the way, even the criticism.

</comment><comment><USER7> I think that AGI is a poorly understood concept and whatever it would signify, we're a couple of paradigm shifts away from it. One thing that bothers me is how there is little concern of legal personhood here, apart from popular action film style "rebellion" fears. (Let's remind ourselves of the 8 billion human level intelligences we're having right now, mostly not wreaking much havoc _individually_ ).

Let's say that some organization builds an AGI that's conscious and capable of human-like thoughts. There's an argument to be made that at that moment, if we don't immediately grant the AGI personal and political rights of citizens, this organization is essentially owning slaves. Which is contrary to the rules of our societies and never ends well. It seems likely to me that, barring some immediate and fantastical gains from AGI that would allow the organization to "break" the society, it would be soon forfeited as property with no compensation.

Which makes a commercial venture to build AGI a dubious proposition.

</comment><comment><USER8> Given that we don't even know AGI is logically possible, probably isn't, unsurprising a company founded on that idea will flounder insofar as it stays true to the goal.

<comment><USER9> I have to say I've never heard this argument before. Why would AGI be logically impossible? Didn't we humans evolve to possess AGI?

<comment><USER10> I don't know if AGI is possible or not but I do think this is a valid question. The AI risk people gloss over this fundamental question and proceed directly to the question of "AI safety". This is a major weakness in their argument.</comment></comment></comment>


Ask HN: What are the deals that Startup School companies receive? - <AUTHOR> YC posted a blog post listing vaguely that AWS, GCP, Clerky, Stripe will be taking part, but what are the specific details of the deals? How much hosting credits etc.<p>So far, how has Startup School been for the companies? Are you finding it useful and did it live up to your expectations? <comment><USER2> Just found out that AWS is giving a $1000 credit to each company on the current course. I just applied for it and am awaiting confirmation. Still finding out about the rest of the deals, as they will be really useful to us too.

<comment><USER3> Are you part the Startup School class? What is your company? How has the experience been so far?

<comment><USER2> Yes, got accepted into the current stream. My company is HR Partner ([https://hrpartner.io](https://hrpartner.io)).

Only the first week of the course so far, but it has been good. We seem to be in a good group with a great mentor who has excellent communication skills. Had our first 'office hours' meetup this morning that went well. Really looking forward to diving in a bit more and getting some questions answered on how we can best measure KPIs and market more effectively.

Honestly, I didn't know about the bonuses from AWS etc. until my co-founder let me know today, thus my application to Amazon, which will really help us out as we run a lot of services with them already.</comment></comment></comment>


How Google's Rankings Algorithm Has Changed Over Time - <AUTHOR> http://www.seomoz.org/blog/how-googles-rankings-algorithm-has-changed-over-time- <comment><USER2> Could someone shed some light on the "domain authority" piece? Any clue as to how this is determined, speaking qualitatively or quantitatively?

The part about 'links as votes' being less important explains why Stormpulse.com has a higher PageRank than wunderground.com, even though we only have about 35,000 inbound links whereas wunderground has over 12 million.

<comment><USER3> Since this is all a black art and guesswork at best and pseudo-science at worst...

The most obvious and simple method is to get an average PageRank of all pages and if it's higher than average use that figure to bias the results as 'domain authority'.

I think there is some sort of bias towards newness, so more recent links are worth more, and newer sites are biased to have a higher initial PageRank.</comment></comment>

Get Ready for Most Cryptocurrencies to Hit Zero, Goldman Says - <AUTHOR> https://www.bloomberg.com/news/articles/2018-02-07/get-ready-for-most-cryptocurrencies-to-hit-zero-goldman-says <comment><USER2> I've been thinking a bit on this idea - the idea of a cryptocurrency, this network of value going down to zero and if its even possible. I have one example: Bitconnect. [https://coinmarketcap.com/currencies/bitconnect/](https://coinmarketcap.com/currencies/bitconnect/)

This currency us a classic scam. They listed a 1% guaranteed daily interest on investment. Every notable and rationale person can take a look at bitconnect's offering and can see it's a scam/ponzi, or at least, something that's too good to be true. The price peaked $400+ with a market cap of over 2 billion.

After regulatory intervention, the price dropped off a cliff. Of all the tokens to go to zero, one should expect an exposed scam token to be there. But that didn't happen. It dipped all the way down to around $8 and started recovering. During the current dip in crypto market prices, bitconnect is still sitting at 2.63 with over 24million in market cap.

Why is this scam token not at zero? There's something interesting at play here. Factors may include the reporting of market data, the markets themselves exchanging this token, and token hodlers who will not sell.

I wonder if there are other factors that's novel to crypto technology. Possibly something associated with the network effect of these crypto tokens, the proliferation and effects of memes, or the natural of decentralization.

It may simply be that something like this take time to go to zero. In any cases, it seems to be quite interesting the market dynamics of these tokens.</comment>
