I can mix and match any combination by checking&#x2F;unchecking a box in Proxyman.<p>This means there is no need to whitelist localhost for CORS, and other hoops. Another advantage is that you&#x27;re experiencing the app with SSL, so you may notice bugs that you would miss if you&#x27;re used to work with HTTP locally. I&#x27;ve had these bugs which &quot;only happen on production&quot; in the past, and it&#x27;s a nasty thing to deal with because it will be in a rush, since it happens as a surprise, and impacts users immediately. It can also bypass QA if the QA environment is also using workarounds and not a prod-like setup with SSL and the likes.<p>I recommend giving it a try. It&#x27;s a workflow I haven&#x27;t seen promoted anywhere before.</text></comment> | <story><title>How to win at CORS</title><url>https://jakearchibald.com/2021/cors/</url></story><parent_chain></parent_chain><comment><author>88913527</author><text>I can tell you how to lose at CORS in Chrome. If your browser caches a response, and sometime later you mutate the request by adding the &quot;Origin&quot; header it (e.g, add attribute crossorigin=&quot;anonymous&quot; to a &lt;script&gt; tag), Chrome won&#x27;t make a new request. What it will do is use the cached response, which is missing the ACAO response header, and thus the browser rejects a file from its own cache via draconian security policy.<p>There are many ways to lose at CORS and this one is my story.</text></comment> |

(Adam Smith&#x27;s &quot;Wealth of Nations&quot; gives a much better explanation in the first few chapters than I can.)<p>So, the point that you have to register as a security is the point that you start convincing people to own your cryptocurrency as in investment. At that point, your cryptocurrency isn&#x27;t money; because money is meant to be spent.<p>How do you keep the SEC out of your cryptocurrency? Invent a cryptocurrency that functions as money. You will need to figure out how to keep the value stable on a day-to-day and year-to-year basis.

Even leaving aside the tools argument (a human on a bicycle is vastly more energy efficient over long distances than a wildebeest, for example), our sight and hearing are actually pretty good compared to the rest of the animal kingdom.<p>For a certain range of tasks, we have the best visual perception of any species. Our eyes themselves are pretty damn good for close-in and medium range work. The pattern recognition processing that input is very, very good due to our big brains. Tasks like being able to detect a tiger moving through the underbrush. Color vision is also very good (at least in daylight) to better pick out ripe fruit and such.<p>Our directional hearing is better than owls who hunt at night for a living. We can better measure the angle at which a sound source is coming from with around twice the accuracy of an owl. Again due to big brains and very complicated audio processing. The folds in your ears are there for a reason. We aren&#x27;t as sensitive as other creatures like deer, who can steer their big ears (basically parabolic horns) in a particular direction.<p>And hand-eye coordination is far above any other species, even other primates.<p>Don&#x27;t sell yourself short!</text></comment> | <story><title>It looks like you’re trying to take over the world</title><url>https://www.gwern.net/Clippy</url></story><parent_chain><item><author>est31</author><text>These stories about AIs taking over the world in order to maximize a score often contain some computer that escapes the lab or such, in order to maximize some score.

And we don&#x27;t <i>realize</i> it because economic growth seems <i>normal</i>.<p>These clippy stories speak of a not unfounded fear that development might not stop with us, that one day some life form spawns that is even smarter than us, and turns us, the predators, into irrelevant side pieces that need to get out of the way for fulfilling the objective of the more powerful life form, even if it was us who brought that life form into existence or gave it that objective.<p>The forests of today are not inhabited by the life form that first discovered photosynthesis, but instead by highly specialized structures that grow higher so that they can put their competition into the shade. Similarly, just because we are the first highly intelligent + cooperative life doesn&#x27;t mean we will be the top of the world forever.<p>I&#x27;m not saying this with a light heart, I do feel sorry for the future humans, some of whom might even be alive today. But &quot;how to contain reward optimizers&quot; is a tough question, especially due to us running a giant project of reward optimization ourselves.</text></item></parent_chain><comment><author>slibhb</author><text>&gt; But mankind, as a whole, is a clippy optimizer already, albeit a manual one. Right now it is us that is destroying life around us, replacing rainforest with cattle farms and suburban developments. We are already working on farming robots to serve our goals. Does the lizard care if it is crushed by a farming robot&#x27;s wheel or an AI tank&#x27;s chain?<p>We already have a built-in solution for this problem: biophilia. People like nature. Once we stop being poor, preserving nature, living in natural environments with trees and animals becomes a high priority. The people &quot;cutting down the rain forest&quot; will stop once they&#x27;re sufficiently comfortable to prioritize nature over avoiding privation just like the Europeans stopped.<p>We used to built boats out of wood, now we build them out of metal. There&#x27;s no reason we can&#x27;t replace technologies that conflict with our biophilia with those that don&#x27;t.</text></comment> |

The past few years I've been living an expat traveler lifestyle.<p>Yes, other countries have visa requirements; I myself was bitten by the Schengen Zone requirement last time I was in Belgium and Germany. But the point is that I don't need to spend hundreds of dollars, navigate a series of confusing bureaucratic hurdles, and then have my <i>body</i> and bags x-rayed and the minutiae of my personal life cross-examined by high-school graduates on a power trip just to have a 4-hour layover in most other countries... unlike America.<p>To contrast this, the last international flight I took was entering Mexico last month (where I am now); the line was long, but I wasn't asked a single question before my passport was stamped. The 2nd to last international landing I had was in Belgium: I was asked the purpose of my visit and was waved along in 30 seconds.<p>The most complicated visa requirement I've run in to was Vietnam, which required a stamped visa to be processed before you crossed the border. Even then it was a matter of giving $25 to my travel agent along with a short customs-style form.<p>Yes you can say that, say, an Iraqi citizen will have a hard time getting in to any country, not just the US; but when we're talking people from England, Europe, China, hell, even Mexico and Canada--neighbors and close allies for generations--the process can <i>still</i> be harrowing. And that's not just unfriendly, it's damaging to relations in the long-term. 20-something backpackers who get hassled crossing into America today, or who choose to go to a different country for 6 months instead of face American border bureaucracy, will take those experiences with them when they enter industry and leadership positions in the future.<p>Edit: another anecdote--on entering New Zealand I was asked for proof of onward travel (as I later found out, a requirement to enter the country). I didn't have any; I had planned on staying a few months then carrying on to Australia when I felt like it. When I told the agent this, she laughed and waved me on.

For all intents and purposes, encryption is a unbreakable lock that can serve to perfectly hide valuable criminal evidence. Such a thing wasn&#x27;t possible when our laws were written and has never before been possible in the physical world. Its existence has potential to be a huge shift in how we enforce the law. Regardless of our views on encryption, we need to have a conversation about that shift. Refusing to have that discussion is likely a quicker path to things like government enforced backdoors than if we engaged with government and law enforcement on possible alternatives.</text></comment> |

I am a libertarian and I've spent 90% of my time post college life running or helping to run a food pantry in my spare time. Seems silly to suggest that libertarians don't care about such things.</text></item></parent_chain><comment><author>entangld</author><text>&#62;&#62;I have work I need done now that I just do not have time for.

They need a job that will pay bills for a reasonable amount of time in the future. They need to save money to live on during the next job search. Temporary low paid jobs just leave the employee stressed out and barely above water before they need to search again. I don't think many people enjoy looking for work.</text></comment> |

The Sun is getting hotter and in ~1 billion years the Earth will be uninhabitable by us in its current form.<p>Eventually (~4-5B years) the Sun will expand while in its dying stages and probably swallow the Earth.<p>What can we do? That&#x27;s actually quite &quot;easy&quot;. I mean &quot;easy&quot; in the essence that no weird new physics is required, it&#x27;s just an engineering problem, albeit a massive one. Then again, we have a lot of time. So there are essentially three things we can do:<p>1. Reduce the amount of light and heat hitting the Earth. Example: large arrays of solar power collectors at the L1 Lagrange point. If the Sun is 10% hotter in 1B years and you reduce the light hitting the Earth by ~10% it about evens out. The captured energy can be put to use and I expect it wouldn&#x27;t even be noticeable from Earth. The Sun will just be slightly dimmer;<p>2. You can move the Earth. Many people are familiar with gravity assists for spacecraft. Obviously gravity affects both bodies but the spacecraft is so low-mass it has no discernable effect on the larger body. Imagine taking large rocks and flying them past the Earth. The net interaction can be that the Earth moves slightly faster. Do this over a long enough time frame and you can move the Earth&#x27;s orbit outwards.<p>3. The Sun itself can be manipulated to remove mass from it, particularly Helium.<p>A lot can be done in a billion+ years.</text></comment> | <story><title>Photos from NASA's Perseverance rover indicate ancient flash floods on Mars</title><url>https://www.science.org/doi/10.1126/science.abl4051</url></story><parent_chain><item><author>harwoodleon</author><text>I was watching the ISS live feed going over North West Africa and up to Italy.

Accounting for model uncertainty, that envelope would likely be tighter than it could be if we knew our physics better, but that&#x27;s still far better than a black box ML model that doesn&#x27;t give you guarantees that similar inputs will lead to similar outputs (there&#x27;s a mathematical formalism to this whose name escapes me now).</text></comment> | <story><title>Machine Learning Reproducibility Checklist [pdf]</title><url>https://www.cs.mcgill.ca/~jpineau/ReproducibilityChecklist.pdf</url></story><parent_chain><item><author>sillysaurusx</author><text>This checklist has some flaws.

All you do is run wiring down the wings, with the Osprey you&#x27;re running pressurized, flexible fuel lines into a movable nacelle with enormously complex turbomachinery to do all of the compression + combustion. These things are a pandora&#x27;s box of fatigue problems from the multimodal vibrations and it takes years to analyze them all.<p>You also can&#x27;t compare operating costs of a military vs. civil aircraft. VERY different priorities, military aircraft have dramatically higher requirements due to where they operate (desert sand anyone?) and their mission. EVERYTHING gets inspected, components are designed to be performant like Formula 1 race cars and not necessarily for lowest operating costs. It&#x27;s like comparing an M1 tank, which gets 0.5 mpg, to a Ford F150.<p>&gt; What&#x27;s weird about mounting propellers at the end of the wing is that you lose half the lift of the propeller wash over the wing, over a normal placement.<p>This is nonsense, there&#x27;s no rule of the thumb that states any random wing reduces prop thrust by 50%. You must calculate it. It&#x27;s a very complex unsteady flow field dependent on all of the geometries involved. It will vary on flight condition obviously.<p>&gt; informal aerodynamics student<p>I&#x27;m sorry but the average pilot&#x27;s understanding of aerodynamics is very poor. I&#x27;ve seen blatant mistakes in flight manuals. At the least you should know how to explain what Reynolds number and Kutta condition are before diving into these discussions.</text></comment> |

Suppose the plan states that hold A and hold B need to be 11 holes apart. In the true spirit of the off-by-one error, this can be interpreted in 3 ways:<p>- either as 11 empty holes between the holds;
- as 11 holes, start counting 1 just above hold A;
- or as 11 holes, start counting with hold A as number 1.<p>Another real-life example, is a plumber who tells the construction worker that the distance between the holes for hot and cold water needs to be 15 cm. This was meant to be measured center to center, but the constructor worker interpreted it as the distance from the right side of the first hole to the left side of the second. The result can still be admired in our house, 10 years later.</text></comment> | <story><title>A Real Life Off-by-One Error</title><url>https://leejo.github.io/2024/09/01/off_by_one/</url></story><parent_chain><item><author>AEVL</author><text>Not an off-by-one error—at

If a manager leaves work unassigned and you pick it up, prepare to have a LOT more work dumped on you in the future for no reward.<p>2. If you pretend to be a manager with hopes of being made a manager, all that you will accomplish is you are going to end up doing your job AND your bosses job. Your boss will look like a hero to his&#x2F;her peers. You&#x27;ll kill yourself and won&#x27;t be made a manager regardless.<p>A better approach is to be smart about it. Always negotiate the work and what you&#x27;re going to get out of it ahead of time. Maybe you just get some political capital, praise, or a positive review.

What portion of your typical day would you honestly say is devoted to solid, in-the-flow work? After all the meeting, context switches, random interruptions, lunch, distractions on company chat -- I personally would say a fraction. Or flow state is simply dead for me at the office.<p>Recently, my roommate and I came home after work and ended up knocking out a very useful skunkworks project in about 6 hours over the course of 2 nights. That completely uninterrupted time mixed with the fact that it was a project that was freshly conceived and still full of passion in our minds let us get more work done in that burst than we felt like we had in weeks.<p>20% time is a joke. We need to ditch this 40 hour, strictly scheduled workweek in distracting office environments and try some radically different ways of getting productivity boosts. It just so happens that people also feel a lot better when they get these boosts to boot. I know after knocking out that project certainly made me feel awesome.</text></comment> |

My answer is always no.<p>Then I launch into a rant about the Wheel of Time series. I got sucked into that series on book one and chewed through it all the way to book 7. At book seven I had caught up to the author and the fact that he hadn&#x27;t written the next book in the series yet gave me an opportunity to take stock. I realized that the books had been getting less satisfying and more work to read than before. I also realized that Robert Jordan didn&#x27;t know how to finish the series. He hadn&#x27;t met a plot line he didn&#x27;t like. I was sure he would die before Wheel of Time was finished. Right then and there I decided I was done and would no longer give my money to the series or any other series that showed signs of the same problem.
I totally called the Wheel of Time. Robert Jordan died and they had to bring in Brian Sanderson to finish. Brian definitely knows how to finish. But for me the magic had already gone.<p>It&#x27;s not out of a sense of entititlement. I just don&#x27;t enjoy unfinished stories. It bugs the crap out of me. George R. R. Martin strikes me as an author with different symptoms but a similar problem. I&#x27;m not sure he knows how to finish it. I won&#x27;t spend my money until he proves it.</text></comment> | <story><title>Entitlement issues (2009)</title><url>http://journal.neilgaiman.com/2009/05/entitlement-issues.html</url></story><parent_chain></parent_chain><comment><author>logfromblammo</author><text>Creative writing is, much like software development, one of those jobs where you need to enter a different kind of mental state to be really productive. And that state cannot be maintained indefinitely.<p>George R.R. Martin writes big, fat books that are highly multithreaded, as part of a series that is already complex enough that it makes real life seem simple. If it were a software project, there would already be four or five more developers working on it. But he&#x27;s trying to punch it out solo.<p>I don&#x27;t expect him to finish, really. He&#x27;s probably burned out for the second or third time, at least, and is getting too much fan pressure resulting from the television adaptation bump to focus on regenerating the artistic mojo.<p>If you ever read bestselling authors, they&#x27;re always thanking their support people in the dedication or foreword or colophon or wherever. Most of them only need a few part-time or shared employees, like their editor, agent, and publicist. Martin probably needs at least one full-time assistant just for indexing and continuity.<p>This is why I like books that say &quot;third book of the Whatever Trilogy&quot; and the other two are right there on the shelf next to it. It lets me know that the author can finish something, and I don&#x27;t have to wait for it to happen.<p>I did read the first few books in Martin&#x27;s series, but I borrowed those copies. I don&#x27;t really want to get sucked in and be left hanging like those people who got into Wheel of Time. With something like this, you never really know if the bus that just pulled away was the last one on the route for the night. So if you sit on that bench, the next one may never come.</text></comment> |

Party discipline is <i>extremely important</i> in the UK system, maintained by the &quot;whips&quot;. Few UK MPs carry their own seat as an individual, although good constituency work can be worth a few thousand votes. One or two have managed to run as independents; Peter Law (ex-Labour protesting against all-women shortlists), Richard Taylor (Kidderminster Hospital).<p>Tony Blair was notorious for imposing ideological coherence from the top on the Labour party with pagers in exactly the way you are talking about: MPs were expected to keep exactly to the media line agreed by Blair and Campbell, and hide all dissent to avoid &quot;PARTY SPLIT&quot; headlines.<p>Note how the conservative party managed to campaign against itself for the Brexit referendum and has now seemingly zipped that right up again. Although the three Brexit ministers keep issuing daft announcements that have to be countermanded by the PM (this is called &quot;cabinet collective irresponsibility&quot;).<p>It&#x27;s worth comparing UK parliamentary elections with the regional parliament elections, which are all run on different systems with very different results.<p>US parties have traditionally been extremely strong. What has happened is that the US rightwing media &quot;bubble&quot; has taken over doctrine and thrown away the doublespeak. Trump is winning because he can say all the unpleasant things that other Republicans feel they have to dogwhistle or hint at.</text></comment> | <story><title>Iceland, a land of Vikings, braces for a Pirate Party takeover</title><url>https://www.washingtonpost.com/pwa/#https://www.washingtonpost.com/world/europe/iceland-a-land-of-vikings-braces-for-a-pirate-party-takeover/2016/10/23/f1bfe992-9540-11e6-9cae-2a3574e296a6_story.html</url></story><parent_chain><item><author>mseebach</author><text>&gt; In America, as has so often been proven, the system is rigged to prevent alternatives to the established parties.<p>But the difference is that the parties in the US and the UK aren&#x27;t very powerful in their own regard.

SQL is not an ideal language, but as a way of expressing intent rather than a physical query plan, it&#x27;s a long way away from C.<p>It&#x27;s hard to appreciate the power of interactive debugger REPLs like binding.pry or JS&#x27;s debugger without experiencing them. A C++ debugger, even a Java debugger, is a pale imitation, and it&#x27;s not easy to simulate the experience without building a dynamic language inside the static language.<p>If all you&#x27;ve ever known is statically typed languages, you can suffer from a myopic parochialism with respect to dynamic typing. IMO the most popular statically typed languages only work well because they have runtime polymorphism holes in their type systems. More powerful statically typed programming languages tend to grow ever more esoteric typing constructs to enable static types to follow dynamic control and data flow - there&#x27;s an inherent tension there and if language complexity isn&#x27;t carefully managed, it becomes harder to express intent and error messages get more vague and cryptic.<p>Algebraic data types and pattern matching tends to be under-appreciated if one is schooled in object-oriented languages. Object orientation has a big hammer for switching control flow based on data values, dynamic dispatch, and architectures tend to leverage dynamic dispatch where they would be much better off with switch statements. If the set of variants is known up front, you&#x27;re probably much better off with sum types and pattern matching than with interfaces, abstract classes and virtual methods.</text></comment> | <story><title>Trying new programming languages helped me grow as a software engineer</title><url>https://cichocinski.dev/blog/trying-new-programming-languages-helped-grow-software-engineer</url></story><parent_chain><item><author>tester756</author><text>I do believe that learning many programming languages is overrated<p>Learn concepts, obtain foundational computer science knowledge, write complex projects<p>not just get familiar with somebody&#x27;s interpretations that they implemented as a language.<p>Languages that I used besides my job language barely gave me anything, in most cases they made me appreciate more for sane environment (package managers, IDEs, debuggers, strong standard library)<p>edit. just to be clear:<p>I don&#x27;t see value in learning C#+Java+PHP, but C#+Erlang? yea<p>I do see value in learning Rust after C<p>but still - concepts are more important, you don&#x27;t have to learn langs in order to be familiar with concepts<p>Learn software engineering - it&#x27;s broad as hell and you can easily do that using one language</text></item></parent_chain><comment><author>larve</author><text>This is pretty much the point of the article.<p>I have a few reasons to work in (not just learn) close languages. The languages might use roughly similar concepts and syntax and solve similar problems (think, C++, C#, PHP, Java, Go), yet their community, practices, tooling, frameworks are wildly different.<p>If as a C++ developer in 2005 you never experienced how smooth debugging and profiling could be in Java, how fast things could compile, how easy it was to drop a jar and deploy to your server farm, you were missing out.<p>Similarly, if as a Go developer you don’t know how quickly you can install WordPress, write a 200 line PHP plugin, and get an entire business off the ground, you are missing out.<p>Most transformational for me was to be a Common Lisp developer, and find the language that allowed the ideas and concepts in my brain to be turned into prototype at the speed of thought. It’s a challenging language to use in the real world, but it really brought the point home that a language is just a vessel for ideas.</text></comment> |

As their paper states:<p>[We] find that, if the program pushes individuals above a threshold level of initial assets, then they escape poverty, but, if it does not, they slide back into poverty…Our findings imply that large one-off transfers that enable people to take on more productive occupations can help alleviate persistent poverty.<p>Their paper clearly illustrates that many poor people stay poor not because of their talent&#x2F;motivation, but because they are in low-paying jobs that they must work to survive.&quot;<p>More on this here: <a href="https:&#x2F;&#x2F;ofdollarsanddata.com&#x2F;why-do-poor-people-stay-poor&#x2F;" rel="nofollow">https:&#x2F;&#x2F;ofdollarsanddata.com&#x2F;why-do-poor-people-stay-poor&#x2F;</a></text></comment> | <story><title>Lambda School leaked documents show poor performance over the last two years</title><url>https://www.businessinsider.com/lambda-school-promised-lucrative-tech-coding-career-low-job-placement-2021-10</url></story><parent_chain><item><author>sam0x17</author><text>This one particular student sticks with me.

[e.g. These agents were not involved]<p>&gt; The charges stem from the agents’ role in one of the federal investigations into Silk Road; a separate Manhattan-based investigation ultimately led to the filing of charges against the website’s founder, Ross W. Ulbricht, who was convicted last month on numerous counts. The website was also shut down by the authorities.<p>&gt; The Baltimore investigation resulted in an indictment of Mr. Ulbricht on a charge of murder for hire, but that case has remained pending and the evidence in support of it was kept out of the New York trial, apparently because of the investigation into the agents.<p>However, I&#x27;m pretty sure the &quot;murder for hire&quot; trial is going to die quietly because of these agents.</text></comment> |

In the last 25 years or so, we actually got something like a pop culture, similar to what happened when television came on the scene and some of its inventors thought it would be a way of getting Shakespeare to the masses. But they forgot that you have to be more sophisticated and have more perspective to understand Shakespeare. What television was able to do was to capture people as they were. So I think the lack of a real computer science today, and the lack of real software engineering today, is partly due to this pop culture.<p>[1] <a href="http://queue.acm.org/detail.cfm?id=1039523" rel="nofollow">http:&#x2F;&#x2F;queue.acm.org&#x2F;detail.cfm?id=1039523</a></text></comment> |

Not only was John Bradmore a surgeon, he was also something of metalworker (and in fact, was arrested for making counterfeit coins; he had to be pulled out of jail to save the king&#x27;s life). He used that skill to design a bespoke tool to pull the arrowhead out of the king&#x27;s head, creating an antibacterial environment with honey and disinfecting the wound with alcohol (though this was before germ theory).

Obviously, Galen believed incorrectly that the human heart has sinuses from which blood flowed across and was filtered, but to his defense he was not allowed by the state to perform human dissections.

It&#x27;s Economy+ on United, Delta Comfort on Delta, Premium Economy on American, Main Cabin Select on Virgin America, Even More on JetBlue, etc. I found this out through looking at the front page of each of their websites. Prices range from $40-50 (additional) per seat per leg. You can select it upon seat selection at the airline&#x27;s website (which is where an aggregator will take you, anyway): the extra economy+ seats that are available are shown together with the price for the update, and you just have to click on them and it will adjust your fare accordingly.<p>So now you know. Incidentally, this is pretty good evidence of this subthread&#x27;s point: you expected to be told all of this by going through a 3rd-party aggregator where you can search by cost. If you are representative of the average American consumer (which is probably pretty likely), it&#x27;s no wonder the airlines compete on cost.</text></comment> |

I trained a bit harder than I should have. I was lucky to never have a significant injury that made me unable to run for more than a couple days, but there were definitely times when I felt burnt out, and I didn&#x27;t compete after high school. Burnout, stress fractures and other roadblocks were very common among kids who ran more than eight miles a day, but many of us had this attitude that we had to take risks and push ourselves. I think we felt pressured because college wasn&#x27;t far off, and we really only had one shot to go D1.<p>I&#x27;d troll a running forum called Dyestat a lot and there was this goon a grade above me who&#x27;d post questions every day about how he should structure his training (e.g. &quot;is increasing 10% per week too much? How long should my long run be?&quot;). The questions weren&#x27;t bad questions, but everyone found them absurd because he&#x27;d run 10, maybe 15 miles in a week. How about spend time actually training instead of talking about training?<p>Because he took his boundaries so seriously, he increased his training load at a snail&#x27;s pace -- I don&#x27;t think he ran a 60 mile week before college. He improved consistently every year, never got injured, and never burned out. He went D2 (D1 &gt; D3 &gt; D2) and killed it.

I trained a bit harder than I should have. I was lucky to never have a significant injury that made me unable to run for more than a couple days, but there were definitely times when I felt burnt out, and I didn&#x27;t compete after high school. Burnout, stress fractures and other roadblocks were very common among kids who ran more than eight miles a day, but many of us had this attitude that we had to take risks and push ourselves. I think we felt pressured because college wasn&#x27;t far off, and we really only had one shot to go D1.<p>I&#x27;d troll a running forum called Dyestat a lot and there was this goon a grade above me who&#x27;d post questions every day about how he should structure his training (e.g. &quot;is increasing 10% per week too much? How long should my long run be?&quot;). The questions weren&#x27;t bad questions, but everyone found them absurd because he&#x27;d run 10, maybe 15 miles in a week. How about spend time actually training instead of talking about training?<p>Because he took his boundaries so seriously, he increased his training load at a snail&#x27;s pace -- I don&#x27;t think he ran a 60 mile week before college. He improved consistently every year, never got injured, and never burned out. He went D2 (D1 &gt; D3 &gt; D2) and killed it. Now at 26 he runs 100+ mile weeks at 6:00 pace and tools on kids at the turkey trot every year. I check his twitter from time to time and it&#x27;s clear he loves the sport as much as I did when I started.<p>I like to think that the difference was that he had a long-term goal that wasn&#x27;t attached to some instantaneous outcome. He wanted to be able to push himself for the rest of his life, even if it meant waiting till past his prime to be any good.<p>I think in general if you make a change that&#x27;s sustainable for the rest of your life, you win.</text></item></parent_chain><comment><author>shubhamjain</author><text>Tiny improvements add up.

In order to do this with optimal safety, you want to have:
<i>genocided all sea monsters, so you don&#x27;t need to worry about krakens and the like
</i>have a means of magical breathing, in case you do end up in the water
<i>rustproofed all your metal armor and other gear
</i>have a large stash of Scrolls of Gold Detection, in a Bag of Holding (itself blessed and stored inside and oilskin sack so that water doesn&#x27;t get in and erase your scrolls)
<i>have a means of safely giving yourself the Confused status
(reading scrolls of Gold Detection while Confused lets you detect magic portals)
</i>a means of swiftly removing said Confusion, so that you can...
*use your Boots of Speed (or other speed-boosting effect) to close rapidly on the moving portal.<p>And that&#x27;s ONE challenge on ONE level (although its deep in the endgame and considered one of the harder things in the game). Now imagine doing that for 100+ levels of gameplay... you CAN virtually guarantee a win in Nethack, but its never fast.<p>I spent a couple years playing hard in college. I read spoilers, and save-scummed for a while, then stopped save-scumming because it wasn&#x27;t fun and I didn&#x27;t need to anymore. I&#x27;ve lost track of my legitimate ascensions - at least one with every class, and then I started in on conducts and score maximization.<p>Now, I still play on and off for a week here or a week there. I can ascend about 1 in 4 times with the easy starting classes like Valkyrie. My YASDs inevitably come from rushing or not thinking things through, plus very occasionally getting screwed early by the RNG.<p>And I&#x27;m not particularly good at the game. Really good players can virtually ascend at will, with the only limitation being their available time.</text></comment> | <story><title>The story behind NetHack's first update since 2003</title><url>http://gamasutra.com/view/news/269726/The_story_behind_NetHacks_longawaited_updatethe_first_since_2003.php</url></story><parent_chain></parent_chain><comment><author>bhaak</author><text>The article is a bit low on actual details why the release happened and what events lead to it.<p>&quot;Why not&quot; doesn&#x27;t adequately describe how ESR released the in-development code to the community without the rest of the devteam knowing about it.

But if you&#x27;re untrained, your body doesn&#x27;t actually know where this point really is.<p>Most strength and endurance gains when you first start training are neurological, where the effect of this feedback loop is pushed back as your body learns the true threshold for muscular damage.<p>The heart does get fatigued though.

Basically, we teach the patcher about the different archive formats that our games use (say, Unreal Engine PAKs) and the algorithm ensures that chunks stop at the file boundaries within the archive, so a chunk doesn’t straddle two unrelated entries. That way when files move around in the archive we can more reliably match their chunks across versions. I think this helped improve download sizes by 5-10% in our case.</text></comment> | <story><title>Zsync: Differential file downloading over HTTP using the rsync algorithm (2010)</title><url>http://zsync.moria.org.uk/</url></story><parent_chain></parent_chain><comment><author>dividuum</author><text>zsync is great. I&#x27;m currently using it to deliver system updates to Raspberry Pis. The system update (and initial install file) is a single install.zip file that gets extracted into the SD boot partition. zsync helps greatly with regards to transfer sizes as a normal OS upgrade is usually between 3-5MB instead of the full 50MB download for the full ZIP.<p>Of course for that you have to specially prepare how to store the files within the ZIP: For example the kernel image is stored, not compressed at it itself is already compressed. gzip based files (like initramfs.gz) are created with the rsyncable flag. And so one for other file types.<p>A really nice feature of zsync is that you can add any number of local data sources when syncing. It then uses all those to search for matching local data before retrieving it remotely. All without any explicit local state or special server side preparations. I usually add the previous and current OS install zip, the currently extracted OS files and previous interrupted transfers. zsync then magically uses all those to reduce download size as much as possible. This also means that the OS can initially reconstruct its own full install.zip file by using its extracted files and fetching the few remaining data chunks remotely.</text></comment> |

There was optimism, there was a desire to install Linux on everything possible, and the GPL was the default license for most new free software that was getting written.<p>It was not without strife. Since 1998, people like esr have been saying how the GPL is passé and is no longer needed because open source won, because open source was superior, because companies would naturally want to share their source code. Nobody needed anymore to be coerced into respecting user freedoms. Then the corporations started to take note and through their clout, they have convinced their employees that nothing is worse than keeping code free. Only unimportant scraps of code can be free, but the real code must remain secret, restricted, proprietary. AGPL is the ultimate evil to be avoided at all costs.<p>I don&#x27;t like this shift. I miss the Slashdot days. I miss the jokes about installing Linux on dead badgers. I wish we had a collective desire to do something about the most widely deployed proprietary software controlling our lives in the pocket computers so many of us carry around with us. We haven&#x27;t won. The code is locked up, the spying is worse than ever, and the corporations are winning. They even influence the direction of Linux, actively trying to subvert GPL compliance efforts such as the VMWare GPL lawsuit by pulling Conservancy&#x27;s funding.<p>The GPL is a much-needed defence. Software controls ever more things of the internet. We need to bring back the rebellious attitude of the late 90s and early 00s. Linux needs to be installed on <i>all</i> of your phone, down to the radio firmware (and the dead badger).</text></comment> | <story><title>The Linux Foundation: Not a Friend of Desktop Linux, the GPL, or Openness</title><url>http://fossforce.com/2017/04/lin-desktop-linux-gpl-openness/</url></story><parent_chain></parent_chain><comment><author>jlgaddis</author><text>I don&#x27;t know enough about this to take sides but I do think that the author of this piece is being a bit misleading on at least one point. This piece says:<p>&gt; <i>... Greg Olson [referred] to the GPL and other copyleft licenses as “Restrictive Licenses” and “viral.”</i><p>The original article, which he then quoted, reads:<p>&gt; <i>These licenses are often termed ‘viral’ because ...</i><p>So, while Mr. Olson <i>did</i> use the term &quot;viral&quot; in his piece, <i>he</i> didn&#x27;t specifically call them &quot;viral&quot;. Instead, he said, quite literally, that &quot;these licenses are often termed &#x27;viral&#x27;&quot; (and they are).<p>Anyways, the open source world has been having this argument forever -- often in the form of whether the BSD v. GPL is more &quot;free&quot; -- and it all depends on whose point of view you&#x27;re looking at it from (the developer&#x27;s or the user&#x27;s).</text></comment> |

It&#x27;s always said that there&#x27;s these crazy tough exams that determine your life in India. For instance this guy apparently spent 11 years trying to pass. Totally unlikely, who would do that? The point seems to be to underline the importance of exams in India.<p>Second, the method of cheating is some badly explained but intricate mechanism. Badly explained in that the story is not complete, how exactly is the Bluetooth used? Intricate in that it&#x27;s some weirdly complicated thing like getting an operation to have this implanted. It&#x27;s always something that sounds way too complex to be worthwhile.<p>Third, the authority in charge of catching the cheaters seems oddly well appointed. Would you really send a special squad to check these kinds of things? Sure, check for hidden notes and phones. You really gonna check for Bluetooth? I mean maybe but I doubt it. How could the guy have a crazy special plan for implanting the thing in his ear but not have anything other than an ordinary plan for smuggling in the phone?<p>To me it reads like that story of a religious couple that don&#x27;t know how babies are made. Comes about now and again, makes us chuckle, says something recognisable about society, but ultimately sounds not quite true.</text></comment> | <story><title>Medical student surgically implants Bluetooth into own ear to cheat in final</title><url>https://www.independent.co.uk/asia/india/mbbs-student-bluetooth-cheating-bhopal-b2021217.html</url></story><parent_chain><item><author>PragmaticPulp</author><text>I&#x27;m extremely skeptical of this story, at least as written.<p>It makes great clickbait, but it doesn&#x27;t really make sense. <i>Where</i> would someone implant a bluetooth earpiece into their ear?

It&#x27;s most likely a procedure similar to rhinestone implants[0].<p>As for why they use a 1-way device: this method of cheating has been around for decades; you get someone to take the test, they leave early and radio answers in. I don&#x27;t know the specifics for this particular exam, but India is certainly not the only place in the world w&#x2F; extremely competitive admission exams. Back in my days back home some twenty years ago, cram schools would be on stand-by outside school doors, they&#x27;d smuggle the question sheet out somehow and flash-solve them &#x2F; publish answers on the spot for publicity. You could get a full answer sheet online from a cram school website before the exam was over (these exams are hours long) and test takers would frequently do so after finishing their exams to see how they did.<p>[0] <a href="https:&#x2F;&#x2F;www.bodycandy.com&#x2F;blogs&#x2F;news&#x2F;microdermal-implants-body-jewelry-wave-of-the-future" rel="nofollow">https:&#x2F;&#x2F;www.bodycandy.com&#x2F;blogs&#x2F;news&#x2F;microdermal-implants-bo...</a></text></comment> |

And even though they present themselves as being &quot;successful&quot; at making a good living at medical transcription, what they really are making money doing is selling courses and books to people who want to get into the (dying) profession. Of course, they never mention to those people that it&#x27;s increasingly difficult to make a decent living at medical transcription.<p>This isn&#x27;t the first time I&#x27;ve watched social butterfly networkers and salespeople take advantage of people and engage in ethically dubious conduct, so I have a bad taste in my mouth regarding networking.

You don&#x27;t need to spend 5K+ to do so. The technology in mountain biking has really taken off in the last 15 years. I can ride trails that only people on downhill bikes would have done 10 years ago, and the bike weighs less than 30lbs, making pedaling up hills not a problem. Enduro mountain bike racing has really taken off in the last few years and really captures the essence of
mountain biking. It&#x27;s a good time to be into mountain bikes.

And existing solar&#x2F;wind operating costs are small, so their energy can be priced very low on day ahead and hour ahead markets, making it hard for fossil&#x2F;nuclear to cover their operating costs.<p>But renewables are intermittent, and adding storage pushes the costs of renewable + storage above existing nuclear operating costs and most new build nuclear options. And storage isn’t lossless—I wouldn’t bet on those batteries holding charge affordably for more than a couple days.<p>We’ll probably muddle through with fossil + renewables for a while, which is the cheapest combo. When we get to the point of trying to take the last 20% of the fossil down is when we might regret not trying harder with nuclear, and in the meantime nukes will continue to struggle with selling energy at a competitive price. But hey, we’ve got another ten years until we phase out the last of the fossil (at the earliest) so maybe some storage cost declines will make it easier. Here’s hoping. Nukes are getting more expensive not less, so I don’t have much expectation they’ll be in the generation mix by the end of the century.<p>[0] <a href="https:&#x2F;&#x2F;www.lazard.com&#x2F;perspective&#x2F;levelized-cost-of-energy-levelized-cost-of-storage-and-levelized-cost-of-hydrogen&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.lazard.com&#x2F;perspective&#x2F;levelized-cost-of-energy-...</a></text></comment> |

In children the whole thing is much smaller. So they hear much-smaller wavelengths of sound which means higher-pitched sound. As we grow so does the cochlea so we hear lower and lower sounds and lose the sensitivity to the highest-pitched ones?<p>I&#x27;m guessing that hair dryers have a scream in the upper register that adults don&#x27;t normally hear.</text></item><item><author>akerro</author><text>That&#x27;s not the only reason why children hear more and louder.

Today, I am much better at putting myself in the learning mindset because I have learned a basic truth: <i>learning is essentially the same as temporarily making a fool of myself, but in a safe place</i>. That&#x27;s how we all learned to walk, talk, and read, after all. If we can learn such complex skills as those then we can surely pick up a lot more skills, with effort.<p>I wish I had understood that as a child. I tried to learn to dance and act, but I mostly failed because I didn&#x27;t really put myself out there. I did learn to sing thanks to choirs. I got into computers partly because all my mistakes were completely private.<p>There&#x27;s no reason I can&#x27;t continue to learn new skills. I just need to shed my ego and try things without reservation.</text></comment> | <story><title>The fertility of the older mind</title><url>http://www.bbc.com/future/story/20170828-the-amazing-fertility-of-the-older-mind</url></story><parent_chain></parent_chain><comment><author>kevmo</author><text>I am 33, and I have paid a lot of anecdotal attention to what seems to keep my brain fresh, i.e. able to still learn new skills at a rapid clip. Just by way of credentials: I was a successful lawyer for a few years of my 20s (rising to level of federal law clerk), but then taught myself to program and have been working as a professional programmer since shortly before my 30th birthday. Even though I am on the older side of the programmer market, my career has been great, and I&#x27;ve been able to rapidly rise in the ranks. I also know a fair amount about design and business strategy now.<p>The secret seems to be: Practice. If you want to be able to do new things, you need to always be doing new things. I am always trying to learn something new - mentally and physically. For example, I am very right-side dominant in my body, but I have lately been trying to open more doors with my left hand, throw stuff at the trashcan with it, etc.<p>Always be doing at least one new thing in your life if you want to be doing new things for the rest of your life. It is OK to fail at a new thing! You just have to admit failure, pat yourself on the back for your courage, take stock of what went right and wrong, then pick a new new thing to do.<p>Relatedly, I have noticed that some people who I considered much smarter than me as a teenager often no longer appear to be, and I believe it is because they stopped trying to grow new types of skills and thus let their brains stagnate.<p>It is hard to do unfamiliar things, but so worth it.</text></comment> |

Expansion is cheap in America. It makes a hell of a lot more sense to expand to another US city than it does to expand to Norway or New Zealand; but for a company in those countries, expansion is very expensive, expanding requires new laws, regulations, business entities, and languages, and shipping costs more.<p>(fact) America is geographically isolated from war, can&#x27;t be invaded, isn&#x27;t saddled with war or reconstruction debts.<p>(fact) Also by virtue of geography, America can produce everything: it has plenty of space to create anything it needs, from mines to farms to factories.<p>(fact) Americans are ambitious to a fault. I am an American living overseas, and possibly one of the most offensive things anyone has said to me here is &quot;you should lower your expectations&quot;.

Expansion is cheap in America. It makes a hell of a lot more sense to expand to another US city than it does to expand to Norway or New Zealand; but for a company in those countries, expansion is very expensive, expanding requires new laws, regulations, business entities, and languages, and shipping costs more.<p>(fact) America is geographically isolated from war, can&#x27;t be invaded, isn&#x27;t saddled with war or reconstruction debts.<p>(fact) Also by virtue of geography, America can produce everything: it has plenty of space to create anything it needs, from mines to farms to factories.<p>(fact) Americans are ambitious to a fault. I am an American living overseas, and possibly one of the most offensive things anyone has said to me here is &quot;you should lower your expectations&quot;.

Canada though, not often considered a real economic dynamo in the same way as the USA.<p>Well one big difference is that Canada is a relatively small population spread thin over an enormously large area.<p>In Canada there&#x27;s a natural and easy North&#x2F;South transportation and trade links, but East&#x2F;West nature of the country breaks that. I read somewhere that prior to Canadian Confederation the Maritime provinces did thriving business with the North East United States trading easily using sea links, but after confederation tariffs ruined this trade, and trade with Quebec and Ontario was more expensive and not as viable. The Maritimes never really recovered their pace.<p>It would be remarkably simpler for a Vancouver company to expand into Seattle and Portland for example, but keeping within the Canadian borders the next natural expansion point is all the way over in Calgary, dramatically far away and a (surprisingly) remarkably different politicial and cultural environment.<p>Some of these problems for Canada mitigated after NAFTA in the 1980s, but still one can see here how the USA is in a better position with its huge and spread out population.</text></comment> |

Jobs or customers per day is something to tell you banker, or investors. For tech people it’s per second, per minute, maybe per hour, or self aggrandizement.<p>A million requests a day sounds really impressive, but it’s 12req&#x2F;s which is not a lot. I had a project that needed 100 req&#x2F;s ages ago. That was considered a reasonably complex problem but not world class, and only because C10k was an open problem. Now you could do that with a single 8xlarge. You don’t even need a cluster.<p>10k tasks a day is 7 per minute. You could do that with Jenkins.</text></comment> | <story><title>SQL Maxis: Why We Ditched RabbitMQ and Replaced It with a Postgres Queue</title><url>https://www.prequel.co/blog/sql-maxis-why-we-ditched-rabbitmq-and-replaced-it-with-a-postgres-queue</url></story><parent_chain><item><author>nemothekid</author><text>&gt;<i>To make all of this run smoothly, we enqueue and dequeue thousands of jobs every day.</i><p>If you your needs aren&#x27;t that expensive, and you don&#x27;t anticipate growing a ton, then it&#x27;s probably a smart technical decision to minimize your operational stack.

You can have lots of readers but not really a lot of writers, and in order to pop a job off of the queue you need to have a process spinning waiting for work, move its status from &quot;to do&quot; to &quot;in progress&quot; and then &quot;done&quot; or &quot;error&quot;, which is sort of &quot;write&quot; heavy?<p>&gt; An EXCLUSIVE lock is needed in order to write to the database file. Only one EXCLUSIVE lock is allowed on the file and no other locks of any kind are allowed to coexist with an EXCLUSIVE lock. In order to maximize concurrency, SQLite works to minimize the amount of time that EXCLUSIVE locks are held.<p>&gt; You can avoid locks when reading, if you set database journal mode to Write-Ahead Logging (see: <a href="http:&#x2F;&#x2F;www.sqlite.org&#x2F;wal.html" rel="nofollow">http:&#x2F;&#x2F;www.sqlite.org&#x2F;wal.html</a>).</text></comment> |

I worked at a major winery that had dozens of tanks, up to 100,000 liters each. A single failure in a tank represented many millions of dollars. Our extremely expensive micro-oxygen pump used a standard 7-segment display combined with little red LEDs representing On&#x2F;Off next to a list of tank numbers. The 7-segment display was used to read and to set the units (μg, mg , etc), amount, and rate of oxygen delivery. I never made the mistake of misconfiguring, but one of the senior Winemakers did resulting in some very angry customers, a 7 figure loss, and many contracts.<p>I&#x27;m left with two opinions: 7-segment displays are not usually fail-safe, and have the potential to be fail-deadly (figure 1). In my entire life I&#x27;ve never had occasion to use a tool with a 7-segment readout, handheld or otherwise, that actually failed or that I misread due to ambiguity.<p>So, I think a better conclusion would be don&#x27;t use 7-segment displays in important places.</text></comment> |

Turn it on and it&#x27;s mitigated, if it&#x27;s off kernel pages and user pages live in the same tables and are thus vulnerable. However AMD&#x27;s official stance is KPTI off-by-default, so generally they are still vulnerable unless you manually enable KPTI.<p>(their ass is covered by the &quot;obey good security practices&quot;, i.e. if you actually care you should be turning it on because it&#x27;s a good security practice in general, but it would nuke their benchmarks just like it did to Intel, so they want it off by default since that&#x27;s how things are usually benchmarked.)<p>The paper describes several approaches, some of which can be mitigated (the time and power measurement attacks) and some of which cannot except via KPTI (TLB-Evict+Prefetch).
