Always nice to see an end-to-end compiler example for a real programming language.<p>Unfortunately, real programming languages are very complex, so writing compilers often gets bogged down in complexity, edge cases, and &quot;mop up&quot; work. Often it can be better to learn on a simpler language where you can afford more focus and more depth before things get too complex.<p>Most &quot;write a compiler&quot; tutorials end up focusing predominantly on having a <i>working</i> compiler rather than one that produces well-optimized code. I decided to write a blog series dedicated specifically to implementing compiler optimizations for a simpler programming language -- the one from last year&#x27;s Advent of Code day 23.<p>It&#x27;s called Compiler Adventures and every episode in the series describes and implements a new optimization, like no-op elimination (ep. 1), constant propagation (ep. 2), value numbering (ep. 3), value range analysis (ep. 4, coming out in a few days), etc.<p>Check it out here: <a href="https:&#x2F;&#x2F;predr.ag&#x2F;blog&#x2F;compiler-adventures-part1-no-op-instructions&#x2F;" rel="nofollow">https:&#x2F;&#x2F;predr.ag&#x2F;blog&#x2F;compiler-adventures-part1-no-op-instru...</a></text></comment> | <story><title>A Compiler Writing Journey</title><url>https://github.com/DoctorWkt/acwj</url></story><parent_chain></parent_chain><comment><author>hardwaregeek</author><text>Always nice to see compiler tutorials that extend beyond the common &quot;compile a calculator to a stack machine&quot; genre.<p>I&#x27;ve recently restarted writing a compiler for fun and I&#x27;ve found that the hardest part is actually psychological. There&#x27;s so much stuff I want to put into the compiler and language, so I often end up a little overwhelmed. When that happens it&#x27;s important to just focus on the code and get something done.<p>It&#x27;s also very easy to get myself into a rabbit hole, i.e. I&#x27;m using tree-sitter as my parser, but tree-sitter isn&#x27;t designed to be used as a compiler front end, but hmm what if it was, maybe I should write something that automatically translates tree-sitter grammars to Rust AST definitions so that I don&#x27;t have to manually convert a tree-sitter CST to an AST? Sure, I could go down that path, or I could bite the bullet and manually convert the tree.<p>Compilers are great exercises in scoping and prioritization because there&#x27;s so damn many of these rabbit holes.</text></comment> |

I even wrote my own init scripts, so I really understood a lot what&#x27;s going on at startup time. Linux was quite simple at that time. I could write my own init, if I wanted. Unfortunately now this knowledge is obsolete. Systemd is a complex beast which uses a lot of arcane techniques, I&#x27;m hardly understanding it. chroot was a really simple concept, but nowadays people use containers, and they are much more complex than chroot. Logging is complicated. In the past I could try to load and then mount partition from livecd or another OS and read logs, now I don&#x27;t know how to do it. Init scripts were simple bash scripts. They were verbose, may be buggy, but after all they were just bash scripts and every Linux user knows bash, so every Linux user could write or modify init script. Now systemd uses its own format, I&#x27;m spending hours every time I need to write new service or timer for RedHat. SELinux is just so complex. I know about UNIX permissions. They are so simple and elegant. I&#x27;m using them everywhere, when I need security. I could explain them in 2 minutes. SELinux has books. I have those books in bookmarks, may be I&#x27;ll read them sometimes. But until then, I just use copy-pasta from internets to solve my tasks, like allow ssh to listen at non-standard port. I don&#x27;t think that it&#x27;s good, that I have to run some random strings on my computer from root without fully understanding what they are doing. SELinux has binary compiled configurations and some encrypted logs for tools to decipher them, what a mess! Sometimes I just disable it to get things done.<p>Don&#x27;t get me wrong. I think that Linux looks more professional, more robust, especially for system administrators, who can devote their lives to learn about those systems. But for hobbyists, who doesn&#x27;t have a lot of time, Linux became much less transparent.<p>May be if I didn&#x27;t have that prior knowledge, it would be easier to learn those things from scratch. But I doubt it.</text></comment> | <story><title>Build yourself a Linux</title><url>https://github.com/MichielDerhaeg/build-linux</url></story><parent_chain><item><author>djsumdog</author><text>Back in 2002 I ran LFS for a semester and a half.

The field of vision is a <i>little</i> bit limited but overall It’s pretty clear to me that anyone who tries this on will say “wow!”.<p>The problem is that while it’s a cool toy there’s nothing available that’s im aware it that would make me want to spend much money on it. Right now, it’s more of a cool toy to show off at parties.<p>So the issue with a video on the website is:<p>a) it would be hard to have a video that doesn’t oversell or undersell it. Imagine advertising a TV in a magazine to an audience who has never seen a TV before.<p>b) more importantly, if the goal is to sell enterprise then you are now a sales company, not a marketing company. For b2b businesses a website just needs to look professional enough… No one is actually going to look at it. The sales process is higher touch and will be done either offline or via email brochures.</text></comment> | <story><title>Magic Leap 2</title><url>https://www.magicleap.com/magic-leap-2</url></story><parent_chain><item><author>sam1r</author><text>I just cannot fathom how billions of dollars are spent into developing a product -- that is just marketed so poorly.

What a surprise - and honour - to find my website featured here, this morning.<p>I just want to add a comment: because the sounds are drawn randomly, everyone hears something different! So, comments like &quot;it does sounds more like a brook&quot; may be right, but just for one particular user, and particular occurence.<p>Today, the average visit duration time is about 30s... and it takes my engine about that same time to evolve from one sound to another. If you think that you are not hearing something that does sound like rain to you, either reload the page (it will start all over again with a new draw) or give the generator a longer listen, like two minutes (I know, this is a lot of time, on the Internet). Then, you will understand why this rain noise generator is different from others. It really shines over longer listening sessions.<p>How it works? Basically, I have sounds in four categories: Light Rain, Heavy Rain, Thunder, and Water sounds (like those occurring once the rain has stopped). The generator starts by choosing one of these categories (with higher probabilities for the rain, but sometimes, it can start with the water sounds - hence that user comment). For each category, there are dozens of different recordings. So, even if you keep playing rain from the same category, it will keep changing. Staying in the same category or switching to another is governed by a very simple transition probabilities matrix.<p>Also, you can change the spectrum of the rain (white&#x2F;pink&#x2F;brown) by means of the pencil (this setting affects the next draws, so its effect is not instantaneous). Being able to change the color of a natural noise, is an interesting feature, IMHO.<p>Cheers,<p>Stéphane</text></comment> | <story><title>Stochastic rain generator from the author of myNoise.net</title><url>http://rain.today/?</url></story><parent_chain></parent_chain><comment><author>AceJohnny2</author><text>I&#x27;ve been using mynoise.net regularly at home and at work to help me relax or concentrate. It&#x27;s surprisingly effective, especially after you&#x27;ve calibrated it to your hearing&#x2F;headphones.<p>The basic concept is surprisingly simple: each generator is actually a collection of 10 looping sounds, each ostensibly covering a given frequency range. You can achieve really different resulting sounds my adjusting each channel. See for example the different presets (on the middle right of the page) for the Crystal Stream generator. [1]<p>I&#x27;m impressed by the quality of work that Stephane Pigeon put into each of these, and I&#x27;m glad he&#x27;s marketing it well with rain.today :)<p>[1] <a href="http:&#x2F;&#x2F;mynoise.net&#x2F;NoiseMachines&#x2F;waterSpringStreamNoiseGenerator.php" rel="nofollow">http:&#x2F;&#x2F;mynoise.net&#x2F;NoiseMachines&#x2F;waterSpringStreamNoiseGener...</a></text></comment> |

The more ridiculous those total compensation packages may seem to outsiders the more they are built up from RSUs. In theory you should just live off base salary and RSU are the (very thick) icing on the cake, but this is unrealistic in SV. This stock part of the compensation goes a long way to paying for the insane housing in that region. Stocks drop and instantly Bay area income does to.<p>Tech will be effected, but a combination of naiveté and denial
make conversations here seem like tech is safe.</text></item><item><author>nimbius</author><text>This is anecdotal and it might come across as bitter and tonedeaf as someone who is not in a STEM job and cant see the bigger picture very well. Im a diesel engine tech who repairs those big trucks carrying food and shit tickets to grocery stores. the fact that ANY market is completely detached from whats actually happening to Americans is frustrating.<p>My job just cut benefits and hours but we&#x27;re &quot;essential.&quot;
Remember those $1200 checks? Im still waiting on mine. Lenders and banks were supposed to start going easy on loans but ive had two emails and a phone call about the loan for my Silverado this month and wouldnt you know, the caller was excited to mention my stimulus check.<p>A guy who used to be my bartender now couch surfs a few days a week at my place while he looks for work. His mother is getting evicted from an assisted living center in a few days and his girlfriend is sick. She &#x27;works at the Amazon&#x27; so she cant take any time off, but hes hoping if he gets a job at the Flying J at the edge of town he can switch places with her and she can take a few days off.<p>Shops are closing and nobody seems to care. Ive counted 2 furniture stores, a consignment shop, a few barber shops, and half the god damn bars in this town including one that was burned to the ground &quot;mysteriously&quot; over the last two weeks. Someone spray painted a swastika on the late night pizza joint.<p>So yeah this is a recession but it is so much worse than a lot of people think. No school means poor kids roam the street like packs of feral dogs asking for money for food around here.

The housing market in the bay area will go down even more. The last year changes in tax rules such as lower deduction for mortgage interest and municipal taxes had already weakened the market. With RSUs going down, even less people will be able to buy housing, driving the price down. I think my house lost 8% in the last year, pre-COVID19. Sucks for me as a home owner, but I really believed the housing market was over-inflated. If we have layoffs, in FAANGs, I suspect a lot of folks will not be able to pay there mortgage.</text></comment> | <story><title>U.S. Economy Shrinks at 4.8% Pace, Signaling Start of Recession</title><url>https://www.bloomberg.com/news/articles/2020-04-29/u-s-economy-shrinks-at-4-8-pace-signaling-start-of-recession</url></story><parent_chain><item><author>baron_harkonnen</author><text>Tech people will be hit much harder by this than they think.

Before 2008 at lot of these companies still had not capture their full market share, so even in a recession there was room for growth. Now profits in these companies are based on market dominance. Even the big names will likely take a hit as the severity of this recession starts to take hold.<p>Finally in the Bay Area there&#x27;s the looming problem that huge amounts of everything is paid for in RSUs (restricted stock units). The more ridiculous those total compensation packages may seem to outsiders the more they are built up from RSUs. In theory you should just live off base salary and RSU are the (very thick) icing on the cake, but this is unrealistic in SV. This stock part of the compensation goes a long way to paying for the insane housing in that region. Stocks drop and instantly Bay area income does to.<p>Tech will be effected, but a combination of naiveté and denial
make conversations here seem like tech is safe.</text></item><item><author>nimbius</author><text>This is anecdotal and it might come across as bitter and tonedeaf as someone who is not in a STEM job and cant see the bigger picture very well. Im a diesel engine tech who repairs those big trucks carrying food and shit tickets to grocery stores. the fact that ANY market is completely detached from whats actually happening to Americans is frustrating.<p>My job just cut benefits and hours but we&#x27;re &quot;essential.&quot;
Remember those $1200 checks? Im still waiting on mine. Lenders and banks were supposed to start going easy on loans but ive had two emails and a phone call about the loan for my Silverado this month and wouldnt you know, the caller was excited to mention my stimulus check.<p>A guy who used to be my bartender now couch surfs a few days a week at my place while he looks for work. His mother is getting evicted from an assisted living center in a few days and his girlfriend is sick. She &#x27;works at the Amazon&#x27; so she cant take any time off, but hes hoping if he gets a job at the Flying J at the edge of town he can switch places with her and she can take a few days off.<p>Shops are closing and nobody seems to care. Ive counted 2 furniture stores, a consignment shop, a few barber shops, and half the god damn bars in this town including one that was burned to the ground &quot;mysteriously&quot; over the last two weeks. Someone spray painted a swastika on the late night pizza joint.<p>So yeah this is a recession but it is so much worse than a lot of people think. No school means poor kids roam the street like packs of feral dogs asking for money for food around here. Half the country is out of work and the best Bloomberg can come up with is &quot;its the start of a recession dont you know!&quot;</text></item></parent_chain><comment><author>lm28469</author><text>&gt; Startups<p>The problem with a lot of startups is that they aren&#x27;t making a profit when everything is going fine, let alone during a world wide pandemic, sometimes for years.<p>I see it as a wake up call for tech.

He saw a mathematical analogy between the equations for light and the equations for mechanics. The principle of least time (Fermat&#x27;s principle) for light became the principle of least action for mechanics.<p>But the principle of least time does not predict diffraction, just the geometric path of a light ray. It fails when the wavelength of the light is large compared to whatever it&#x27;s interacting with.<p>At the time, the equations for mechanics were clearly failing for small systems. Here&#x27;s where Schrodinger had his incredible insight: what if mechanics broke in <i>the same way</i> as optics? Could matter itself display a kind of &quot;diffraction&quot; when its &quot;wavelength&quot; was similar in size to the objects it was interacting with? Could this explain the success of de Broglie&#x27;s work, which treated small particles like waves?<p>Guided by that, he was able to add &quot;diffraction&quot; to the equations of matter and come up with the Schrodinger equation.<p>It&#x27;s worth reading the original paper if you have a physics background -- probably grad-level (just being realistic.) I&#x27;ve been wanting to write a blog post about this because the physics lore is something like &quot;Schrodinger just made a really good guess&quot; but that totally undersells the depth of his reasoning.</text></comment> | <story><title>Schrödinger equation emerges mathematically from classical mechanics (2012)</title><url>https://www.researchgate.net/publication/241778960_A_Pseudo-Quantum_Triad_Schrodinger%27s_Equation_the_Uncertainty_Principle_and_the_Heisenberg_Group</url></story><parent_chain></parent_chain><comment><author>bluish29</author><text>I don&#x27;t know if there is a rule about science papers links, but I think using the journal paper link [1] is more suitable.

Oktoberfest in Munich led to a big Covid surge with hospitals filling up at a dangerous rate, and experience tells that December will be worse, so their event would almost certainly be severely downsized or altogether disallowed by the authorities. Renewed Covid restrictions are already being debated in German politics with the general expectation being that some restrictions like masks and less or no large events will be imposed. Can&#x27;t do an event at their scale in such an environment, not to speak of pricing issues due to energy etc. that they didn&#x27;t even go into, but that will almost certainly have played a role as well. All of this really, really sucks.<p>It&#x27;s a bit sad that they (apparently?) won&#x27;t be doing a remote replacement, though. I realize you can&#x27;t do a proper Congress remotely, but having some of the nice things (like the talks) sure beats having none. Not sure how exactly those decentralized events will shape out, but their announcement reads like they&#x27;re focusing on the in-person elements, so I have to assume they&#x27;ll be like hackerspace open-door events that cater to the locals.</text></comment> | <story><title>No Congress 2022: Looking forward to decentralized alternatives and Camp 2023</title><url>https://www.ccc.de/en/updates/2022/no-congress-2022</url></story><parent_chain></parent_chain><comment><author>mnd999</author><text>Is it normal in Germany to still be cancelling large events due to Covid?

All assumptions about network robustness in particular will be proven wrong on a long enough timeline.<p>* Leader election in a world without a robust network is an exercise in managing acceptable failure tolerances. Every application has a notion of acceptable failure rates or acceptable downtime. Discovering that is a non-trivial effort.<p>Jeff Dean and others at Google famously came to the conclusion that it was ok for some parts of the Gmail service to be down for limited periods of time. Accepting that all self-healing&#x2F;robust systems will eventually degrade and have to be restored is the first step in building something manageable. The AXD301 is the most robust system ever built by humans to my knowledge (I think it did 20 years of uptime in production). Most other systems will fail long before that. Managing systems as they fail is an art, particularly as all systems operate in a degraded state.<p>In short, in a lab environment networks function really well. In the real world, it&#x27;s a jungle. Plan accordingly.</text></comment> | <story><title>Paxos vs. Raft: Have we reached consensus on distributed consensus?</title><url>http://charap.co/reading-group-paxos-vs-raft-have-we-reached-consensus-on-distributed-consensus/</url></story><parent_chain></parent_chain><comment><author>benlivengood</author><text>Since the article mentions Google as the outlier preferring Paxos, I may be able to shed some light from a few years ago.<p>The Paxos, paxosdb, and related libraries (despite the name, all are multi-paxos) are solid and integrated directly into a number of products (Borg, Chubby, CFS, Spanner, etc.). There are years of engineering effort and unit tests behind the core Paxos library and so it makes sense to keep using and improving it instead of going off to Raft. As far as I am aware the Google Paxos implementation predates Raft by quite a while.<p>I think in general if most other people use Raft it&#x27;s better for the community to have single, stable, and well-tested shared implementations for much the same reason it&#x27;s good for Google to stick with Paxos.</text></comment> |

Try to find the small hole in the very middle of the trunk and drill down into it. This is how the sap flows through the tree. Carefully spray 3-4 good sprays of Glyphosate into the hole with gloves and eye protection. The tree and gravity will take this down into the roots where they will die. The small amount of Glyophosate will stay in the roots for approximately eight years, and it won’t leak out into the soil as it’s held by them.</text></comment> | <story><title>Bradford pear trees banned in few states – More are looking to eradicate them</title><url>https://www.usatoday.com/story/news/nation/2024/03/25/bradford-pear-trees-smell-invasive-species-banned/73040722007/</url></story><parent_chain><item><author>aidenn0</author><text>What herbicide do you use?

You can get excessive jail time just for having some (regardless of quantity) marijuana on you - and that is in &quot;western&quot; country. It was not so long ago that &quot;marijuana had no possible medical application&quot; and was scheduled as a class A drug in UK (and I think, still is). There is a lot of stigma, and decades of bad science, propaganda, and manufactured hatred run deep. Research is difficult, if at all possible because excessively harsh legislation. And who benefits?.. criminal cartels and enforcement agencies. This is also why scientists go such extreme lengths to create psychoactive mimics (&quot;legal highs&quot;) - so they can research the stuff that is at least similar without going to jail. It&#x27;s a fucked up world, my friend.<p>It&#x27;s not the scientists&#x27; approach that is wrong, it&#x27;s the legislators...</text></comment> |

If someone asks you how to achieve financial independence and you tell them to just make half a mil working at FAANG, your advice is going to get filed under the &quot;no shit&quot; folder. I also don&#x27;t quite follow how the author claims to have achieved financial independence while relying on a $600K&#x2F;yr salary from Amazon. This isn&#x27;t the type of content folks usually expect. I think for most people it&#x27;ll be about using their salaries to their potential via smart investing and compounding, while focusing their free time on generating alternative streams of income which will supplement their existing salary. I think this is the foundation of most &quot;financial independence&quot; stories. With that said, I do think that the article is very inspirational to most engineers on here. I&#x27;m a fellow immigrant who has achieved a bit in my life in the US, but not nearly as much in terms of salary. I&#x27;m still grateful and very content knowing that the ceiling is as high as I pretty much want it to be.</text></comment> | <story><title>My Path to Financial Independence as a Software Engineer</title><url>https://software.rajivprab.com/2021/12/26/my-path-to-financial-independence-as-a-software-engineer/</url></story><parent_chain><item><author>deanmoriarty</author><text>I do not understand why articles like these consistently score poorly on HN?

It took long enough.<p>20 years ago I worked there, selling Packard Bell and Macintosh computers, as well as vaccums. Who decided those departments should be merged, I don&#x27;t know. Once in a while I&#x27;d sub at a smaller store about 45 minutes away, and cameras got thrown into the mix.<p>I always liked the Sears Auto Center for tires, service, and Diehard batteries. Craftsman hand tools were decent until the mid-2000&#x27;s when they started changing warranty policies.<p>The power tools and lawn equipment were never really any good. If you buy a &#x27;Craftsman&#x27; mower, you&#x27;re getting the same Chinese-engined lawnmower that you buy at the same price point at any other store. Just like any other product these days.<p>They used to have an entire part of the store dedicated to flat-screen TV&#x27;s. As they cheapened, the area got smaller and smaller, until it was 4-5 sad TV&#x27;s hanging on a wall. Just this last year they decided to fill that part of the store with mattresses.<p>I noticed the store filling up with Craftsman, Kenmore, and other Sears-branded junk. Just low end stuff like cheap shoes, plastic utensils, and pots and pans. I figured distributors weren&#x27;t willing to give Sears enough credit to stock the stores with stuff of any value.<p>The store itself hasn&#x27;t been kept up in forever. Most of the ceiling tiles are stained from leaks. the carpets are probably as old as I am, everything is broken, and it doesn&#x27;t even feel like they turn the heat on in the winter.</text></comment> | <story><title>Sears Hasn’t Fared Better After Bankruptcy</title><url>https://www.wsj.com/articles/sears-hasnt-fared-better-after-bankruptcy-as-another-100-stores-will-soon-close-11570959000?mod=rsswn</url></story><parent_chain></parent_chain><comment><author>zipwitch</author><text>Sears biggest problem is that the now-former CEO had been looting it for years.<p><a href="https:&#x2F;&#x2F;www.reuters.com&#x2F;article&#x2F;us-sears-lawsuit&#x2F;sears-sues-lampert-claiming-he-looted-assets-and-drove-it-into-bankruptcy-idUSKCN1RU1V3" rel="nofollow">https:&#x2F;&#x2F;www.reuters.com&#x2F;article&#x2F;us-sears-lawsuit&#x2F;sears-sues-...</a></text></comment> |

Most of the good coders I know have been doing it from a young age, and I think a lot of it comes from the fearlessness of youth.<p>Personally, I know I owe a lot to this. I "broke" the computer more times than I can count, by just experimenting, playing and otherwise doing stuff that I now know to be "reckless". There was a guy in the IT department and my dad's work who gave me an absurd number of hours of free tech support and teaching, because I couldn't figure out how to undo some of those mistakes, and would patiently walk me through getting things put right before my folks came home from work.

I’m glad that works for you. But it’s a strange reply. I’ve described an attention disorder and a method for coping with it and your suggestion is that maybe I shouldn’t have the disorder in the first place. Which I agree with, but it’s not particularly helpful.
I suppose that’s not fair. Let me try again: I’d love it if I could mindwander a bit while still paying attention to the lecture, the entire problem is that I cannot do this. That inability is called an attention disorder. If I have time to mindwander at all then I immediately get lost in my thoughts and am unable to pay any attention to the lecture.</text></comment> | <story><title>People Who Speed-Listen to Podcasts</title><url>https://www.buzzfeed.com/doree/meet-the-people-who-listen-to-podcasts-at-super-fast-speeds?utm_term=.jdJ8Pn6MBG#.ioEx4N69Mb</url></story><parent_chain><item><author>tw1010</author><text>Lectures isn&#x27;t just about feeding the information into your brain.

If we allow an exact 50% share to count as a “majority” then both nodes can potentially continue to accept and acknowledge updates during the division, because each is capable of updating a majority of the nodes in the cluster (in this case, just itself, but the same argument applies if we have larger numbers of nodes in each half). However, when the division is healed, a simple check to see which leader node has the higher term count and allow its log to take precedence is no longer sufficient.<p>The problem is that we have violated the State Machine Safety guarantee described in the Raft paper (that is, we can have different nodes that have different committed entries at the same index in their respective logs). We now have no way to resolve the conflict, because those updates were already committed by some of the nodes in the cluster and have been acknowledged by their respective leader nodes, so now we can’t just append any extra committed log entries from one node to another node’s log to get back to a consistent state.</text></comment> | <story><title>Neat Algorithms: Paxos</title><url>http://harry.me/blog/2014/12/27/neat-algorithms-paxos/?hn=1</url></story><parent_chain><item><author>Retr0spectrum</author><text>Surely that means that none of the nodes will reach a concensus, so the cluster cannot be updated?</text></item><item><author>nacs</author><text>Ah, thanks for the response.

Getting traffic to online store.<p>2. Converting it to sales.<p>3. Able to deliver it to customers in time.<p>4. Service the complaints or product in time.<p>Out of this website traffic is directly linked to assortment and sales is directly linked to price (value for money vis a vis quality) and delivery besides traffic. Logistics i.e. storing, sorting and last mile delivery is one of the toughest challenges to solve in this business. Amazon used UPS, FedEx and USPS in the beginning to help them understand how its done, acquire expertise. They took that knowledge and than applied technology to solve some of the challenges and reduce costs.<p>It was just a matter of time they become full logistics company, because in reality every retailer and distributor is primarily a logistics company with stores, warehouses and distribution center.<p>So it&#x27;s hardly surprising they are competing with them. But I feel UPS, FedEx still do many other B2B supply chain work like delivering components to manufacturing site, vendor managed inventory, defence supplies, government supply chain, Olympics, major events and sports supply chain etc. so there will still be room for them to grow.</text></comment> |

Newer C programs can be robust as well. In fact, I write C programs both for fun and at work and so do a lot of people I know, and these programs still end up being much more robust than I would even expect myself. And when you run them continuously, you will find some bugs in the program but the next bug will appear much later until you don&#x27;t remember when was the last time a bug caused a failure.<p>There&#x27;s something about the robustness you&#x27;re forced to implement. I never trust scripting languages like that, not mine nor others&#x27;, as much as solid C. I&#x27;ve seen it way too many times that when a C program is well-written solid code, it keeps on doing what it does and doesn&#x27;t give surprises. I&#x27;ve had many Python scripts running for years and I always need to fix something little there every year. Maybe something has changed in some library, or I bump into a new failure mode, or something.

Just control your internal interruptions, stay focused. That&#x27;s all, eh? Hehehehehe</text></item><item><author>sanderjd</author><text>I think the primary point here is that interruptions don&#x27;t only happen <i>externally</i>, but also <i>internally</i>. I think this point is a bit obscured by the article&#x27;s use of this &quot;fragmented thinking&quot; terminology, which it does not do a good job of defining before building an argument on top of it. (I found myself searching for those words to see if I had missed the definition.)<p>However, I do think this is an insightful point! I think these &quot;internal interruptions&quot; are indeed a big problem for me, and one I don&#x27;t think about nearly as much, but will try to more now that I&#x27;ve read this article.<p>The frustrating thing about external interruptions is the inability to control them. Things like turning off notifications and putting on headphones are mechanisms to reduce that frustration by imposing control over those interruptions.<p>The good news for these <i>internal</i> interruptions is that it should be much easier to control them. But it requires being aware of the problem! So I&#x27;m thankful to this article for making this more top of mind for me.</text></item></parent_chain><comment><author>sanderjd</author><text>Not <i>easy</i>, eas<i>ier</i>! For &quot;external interruptions&quot;, you have to do both things, keep people from bugging you <i>and</i> control your own mind. I think it&#x27;s definitely easier to only do one of the two, despite still being really hard.</text></comment> |

The DMV gives you three choices: he picked SAILING, BOATING. If he couldn&#x27;t get those, he didn&#x27;t want a personalized plate, so he put NO PLATE. Of course, he ended up with NO PLATE. Since that&#x27;s what the police put as the license if a car doesn&#x27;t have a plate, he ended up with 2500 tickets. Eventually the DMV told the police to write &quot;NONE&quot; instead of &quot;NO PLATE&quot; and said &quot;We&#x27;re just hoping that no one will come up with plates that say NONE.&quot; (Which would be ironic if the parent comment is accurate.)<p>The article is pretty entertaining - it talks about him becoming semi-famous and getting pulled over because cops wanted their picture taken with him:

On one hand, I totally get that the internet is a massively important portion of most people&#x27;s lives, and people that need special accomodations should be able to participate. On the other hand, accessibility still doesn&#x27;t seem to be easy to implement. I don&#x27;t work on the frontend, so I could be wrong, but last I looked, it seemed heavily manual and somewhat hard to integrate. It will be expensive to implement, at least until someone makes a better abstraction.<p>I suspect the Domino&#x27;s ruling will be the winning one, but I don&#x27;t know where that line gets drawn. Does my blog have to support accessibility? I don&#x27;t sell anything, but it is public. Is the neighborhood softball league going to have to implement it? Commercial entities will probably have to comply, but I&#x27;m curious what the impact on the rest of the landscape will be.</text></comment> |

It only aggregates writes together if you already have in-flight data. The second you get back an ACK, the next packet will be sent regardless of how full it is. Equally your first write to the socket will always be sent without delay.<p>The case where you want to send many tiny packets with minimal latency doesn’t really make sense for TCP, because eventuality the packet overhead and traffic control algorithms will end up throttling your thought put and latency. Nagle only impact cases where you’re trying to TCP in an almost pathological manner, and elegantly handles that behaviour to minimise overheads, and associated throughput and latency costs.<p>If there’s a use case where latency is your absolute top priority, then you should be using UDP, and not TCP. Because TCP will always nobble your latency because it insists on ordered data delivery, and will delay just received packets if they arrive ahead of preceding packets. Only UDP gives you the ability to opt-out of that behaviour, and ensure that data is sent and received as quickly as your network allows, and lets your application decide for itself the handling of missing data.</text></comment> | <story><title>Golang disables Nagle's Algorithm by default</title><url>https://withinboredom.info/blog/2022/12/29/golang-is-evil-on-shitty-networks/</url></story><parent_chain><item><author>jrockway</author><text>Why does a congestionless network matter here?

However that difference appeared to be mostly related to form factor and not necessarily from the screen itself. Studies that used tablets showed smaller gaps in performance than studies that used computers. Studies that used e-ink e-readers showed almost no difference in comprehension. I was not able to find a single study that compared more than 2 or 3 different devices using the same methodology. If I were to design a study I would want to see a full range of tests including print books, e-ink e-readers, tablets with full color screens, traditional computer monitors, and e-ink monitors. Hopefully then you could better isolate the cause of the lower comprehension.<p>My own hypothesis (I have a comp sci degree, so take this psychology explanation with a grain of salt) is that comprehension is more dependent on the person&#x27;s approach to the technology rather than the technology itself.

I have tried to switch to e-readers several times, but it never works. I learn the subject slower and I remember much less of what I read from e-reader. I use computers and e-readers to skim or check some details, but never to thoroughly study.<p>If I read physical book or printed article and underline it, leave coffee stains on the paper etc. I&#x27;m working with actual physical object. When I achieve the paper in a map, I can often recall where the book is stored physically and even the coffee stains and notes in the paper.<p>I think physical book or paper works the same way as memory palace technique. You remember stuff by working with them physically better than in abstract. Physical library might be mirrored in our mind. Ancient augmented memory technology we did not know we have and might lose. E-reader or computer associates everything to the same object.</text></comment> | <story><title>Students learn more effectively from print textbooks than screens, study says</title><url>http://www.businessinsider.com/students-learning-education-print-textbooks-screens-study-2017-10</url></story><parent_chain><item><author>slg</author><text>I did an in depth review of the research for a Human Computer Interaction class in college a couple years back before the Taylor and Francis study and the research then generally agreed with the idea that reading a print book was the best for comprehension (I tried quickly searching for the paper to pull sources, but no luck). However that difference appeared to be mostly related to form factor and not necessarily from the screen itself. Studies that used tablets showed smaller gaps in performance than studies that used computers. Studies that used e-ink e-readers showed almost no difference in comprehension. I was not able to find a single study that compared more than 2 or 3 different devices using the same methodology. If I were to design a study I would want to see a full range of tests including print books, e-ink e-readers, tablets with full color screens, traditional computer monitors, and e-ink monitors. Hopefully then you could better isolate the cause of the lower comprehension.<p>My own hypothesis (I have a comp sci degree, so take this psychology explanation with a grain of salt) is that comprehension is more dependent on the person&#x27;s approach to the technology rather than the technology itself. Books are single purpose devices. When you have a book in your hand your brain knows it is time to focus on reading. When you sit down at a computer, the brain doesn&#x27;t know what to expect or to focus on.

Whenever I hear some big successful entrepreneur saying how everything is better now then it used to be (and sincerely believe this to be the case) - They are proving themselves to be completely out of touch with reality.<p>Sure, today&#x27;s working class can get access to more goods and services than ever before but when it comes to things that actually matter like our time and our ability to feel fulfilled in our work; we have never been so poor.<p>People today are unhappy. Our working conditions are deteriorating and we are starting to feel like slaves. Our rents or mortgages are massive and we cannot afford to lose our jobs. People are no longer allowed to be themselves because saying the wrong thing to the wrong person might have serious negative repercussions for their careers and livelihoods. People are turning to video games and drugs to give themselves the feeling of fulfilment that they desperately need.<p>Based on US statistics I&#x27;m like in the top 5% of household income bracket but I feel like a slave at work - I seriously wonder how people in the bottom 95% must feel!<p>The distribution of income seems so unnatural: <a href="http:&#x2F;&#x2F;money.cnn.com&#x2F;calculator&#x2F;pf&#x2F;income-rank&#x2F;" rel="nofollow">http:&#x2F;&#x2F;money.cnn.com&#x2F;calculator&#x2F;pf&#x2F;income-rank&#x2F;</a>

Effectively, the current approach is mostly fine, it just needs a few tweaks and reforms to turn it into a &quot;social democracy&quot;.<p>If money is the problem, then the solution is not to engage in petty social democratic welfare reforms, but to end the monopoly on currency and allow for communities and individuals to coordinate savings-investment decisions and account for their local capital using the denomination of currency that they have decided to create. This is the mutual credit solution as advocated by 19th century anarchists and a minority of monetary reformers since then.<p>Pfeffer quotes Article 23 on the &quot;right to work,&quot; and indeed full employment has always been a bizarre fetish for Keynesians, social democrats, Marxists <i>and</i> conservatives. The Protestant work ethic is the right-wing version of the labor theory of value. It is a contradiction how so many bemoan the supposed rat race working conditions and then advocate the &quot;solution&quot; of having the state put everyone into the rat race through full employment policy. Nowhere have I seen any social democratic reformer argue for artisanal crafts and decentralized governance. It&#x27;s always more and more massive centralization. I will note it was the mercantilists who first provided economic rationales for full employment. And they went to great lengths to achieve it: anti-vagrancy and poor laws to forcefully turn people into serfs. The current proposals are more humane, but borne of the same logic of &quot;to live is to toil&quot;.<p>I will also note that a reason why formal models haven&#x27;t focused that much on things like subjective utility and happiness is because those suffer from intractable aggregation problems. It&#x27;s easy to speak of the &quot;public interest&quot; in colloquial language, it is brutally difficult to model and quantify it, actually drawing the line of how far it extends. Then, of course, interpersonal comparison of utility is fraught with issues because there is no measurement of utility as such. Robert Nozick&#x27;s thought experiments have been good at illustrating this.<p>This trite paternalistic reformism leads nowhere except to further exacerbation of instability.</text></comment> |

But I haven&#x27;t really explored moving further apart. I suspect that this suffers from a sharp knee where it starts out reliable and then very quickly fades off.<p>To be clear, the 7kbps is the raw frame throughput, not the effective rate with TCP. There are two ways I can see to boost this number. One would be to pack more bits into each symbol, e.g. to use a wider QAM mode. I find that in practice the degradation from using speaker&#x2F;mic makes this somewhat impractical. The other would be to use a more broadband signal (the width of the the main audible channel is a few kHz). But this is also kind of undesirable since it has to compete with more interference across the spectrum and can also be a less pleasing sound.</text></comment> | <story><title>Show HN: TCP over sound on Android</title><url>https://github.com/quiet/org.quietmodem.Quiet</url></story><parent_chain><item><author>steventhedev</author><text>Seems like this would benefit from not using standard TCP (which assumes that a dropped packet is always due to congestion), and maybe use one of the WiFi retransmission protocols (the names are slipping my mind at the moment).<p>Might increase that bandwidth from 7kbps to something more comfortable.</text></item></parent_chain><comment><author>noselasd</author><text>Presumably the old V.42 protocol used for modems would be quite suitable for this - it does re-transmissions.</text></comment> |

The word &quot;pointless&quot; springs to mind.<p>In fact it&#x27;s strange that there is NO useful filtering at all apart from the very useful folder&#x2F;hierarchy&#x2F;prefix filtering. But apart from that you can&#x27;t do wildcard searches or filters or date filters or tag filters.<p>I&#x27;m building an application right now that needs to get a list of all the jpg files - the only way to do that is get every single object in the bucket and manually filter out the unwanted ones - feels like its 1988 again.<p>It seems like it would also be valuable for there to be alternate interfaces to S3 such as the ability to send data via ftp or SMTP or sftp or whatever, but there are no such interfaces.<p>Hopefully Google will goad AWS into action on S3 innovation by implementing such features.</text></comment> | <story><title>Show HN: s3-lambda – Lambda functions over S3 objects: each, map, reduce, filter</title><url>https://github.com/littlstar/s3-lambda</url></story><parent_chain></parent_chain><comment><author>simonw</author><text>First impression: this is a brilliant piece of software design.<p>The ability to compose a map&#x2F;filter chain and execute it in parallel against every object in an S3 bucket that matches a specific prefix - wow.<p>The set of problems that can be quickly and cheaply solved with this thing is enormous. My biggest problem with lambda functions is that they are a bit of a pain to actually write - for transforming data in S3 this looks like my ideal abstraction.</text></comment> |

However I was a pretty heavy user of Twitter - scrolling through my timeline on the tram, in cafes, on the toilet or whenever I had a spare moment. I assumed that the API outage was temporary so I didn&#x27;t download the &quot;official&quot; app, and figured I&#x27;d just wait a day or so for Tweetbot to be fixed. It&#x27;s now been ~3 days, I don&#x27;t miss not having Twitter, I don&#x27;t check it at all. I&#x27;m maybe missing a couple of @dril posts, podcast recommendations or funny images I could&#x27;ve shared with friends but that&#x27;s nothing.<p>So intentional or not, I&#x27;m effectively lost as a Twitter user. I&#x27;m not claiming to be particularly high value, but I don&#x27;t imagine my experience is unique. I&#x27;m quite far from a fan of Musk but I enjoyed my Twitter experience enough that his meddling was just an amusing side-show until now. It&#x27;s not a dramatic rage quit, just a sort of accidental &quot;oh I guess I didn&#x27;t need that&quot; realisation that I didn&#x27;t plan on having at all. Weird.<p>Interestingly if Twitter had said &quot;We are killing off Tweetbot, you have to use our app&quot; I <i>probably</i> would have just begrudgingly downloaded the Twitter app. But because they didn&#x27;t say anything, I just waited and went through the &quot;cold turkey&quot; period, where every now and then I&#x27;d instinctively tap the Tweetbot icon before thinking &quot;ah yeah it&#x27;s down, oh well&quot; - before completely losing that habit. What an own goal.</text></comment> | <story><title>Twitter API Page</title><url>https://developer.twitter.com/apitools</url></story><parent_chain></parent_chain><comment><author>samwillis</author><text>I&#x27;m not sure what that link was supposed to be before it 404ed.

Then flip the switch in the database. Sure, it might be out-of-bounds for normal workflow.<p>My previous employer did something like this. If you currently had the $8&#x2F;month plan for 12 months and chose to switch to the $20&#x2F;month plan, you&#x27;d get it instantly but with (8&#x2F;20) * your remaining time, e.g. 4.8 months if you had 12 months left. (This also worked the other way round for plan downgrades.) Then when it came time to renew you&#x27;d pay a new 12-month subscription fee for a full 12 months.<p>It&#x27;s a very elegant and convenient system. Choose the wrong plan by mistake at time of payment? Want to try the premium plan? You can switch instantly without entering any payment details, and without the provider having an extra payment card fee to stomach.</text></comment> |

Russia supplied and controlled the export of the dried root, thus controlling its price. It banned the export of the seeds to block the growing of the plant elsewhere. Catherine the Great took considerable interest in the cultivation and sale of rhubarb, as it helped to finance her military campaigns in Finland, Poland, Ukraine and Crimea. The price of rhubarb root rocketed! At one time the seeds were more valuable, weight for weight, than gold. To give some idea of the veneration that was given to the plant, Lord Stanhope, a Catholic peer, sent some rhubarb seeds to the Pope in a gold case, encouraging him to grow the plant in the gardens at the Vatican. This monopoly could not last indefinitely. Professor John Hope stated in 1770 that if &#x27;Russian&#x27; rhubarb could be grown successfully in the UK, it would save the economy about £1 million a year (approximately £20–30 million in today&#x27;s money)&quot;</text></comment> | <story><title>In England, rhubarb is grown by candlelight</title><url>http://www.bbc.com/travel/story/20190424-the-english-vegetable-picked-by-candlelight</url></story><parent_chain></parent_chain><comment><author>istjohn</author><text>The article says one can hear &quot;forced&quot; rhubarb grow. &quot;Forcing&quot; is a technique to stimulate growth of sweeter rhubarb stalks by depriving the plant of sunlight.

Can I make one suggestion with regards to business processes? You currently appear to have domain renewals done shortly in advance of need, with manual scheduling. <i>This is a source of risk.</i> There are a <i>lot</i> of failure modes there, including "my registrar fubars the renewal", and many of them have unpleasant consequences.<p>Domain names are cheap and abandonment is infrequent and unlikely to save much money, for most people on HN. So renew them early, for long terms. For your business or blog or other domain which will be a going concern for the foreseeable future, go renew it for ten years. If your business gets sold to Amazon tomorrow, oh well, that cost you only $60 ~ $80 or so.<p>I own a small stable of domains (a few dozen) and keep most of them on rolling two year registrations, with my main ones (product sites, my blog, etc) on rolling five year registrations. I renew all of them yearly. This way, screwups by myself, my bank, Paypal, or GoDaddy probably won't deprive me of use of my property.</text></comment> | <story><title>Moniker Deactivated My Domain 26 Days Before The Expiration Date</title><url>http://peterc.org/blog/2010/345-moniker-deactivation.html</url></story><parent_chain></parent_chain><comment><author>jacquesm</author><text>hey Peter,<p>Mail this guy: [email protected]<p>His full name is Monte Cahn, he's only going to be there for another 3 weeks or so so move while you can.

If I need to load 1000 rows from a database and splash them on a webpage, will my response time go from the 300ms it takes without asyncio to something &quot;more performant&quot;, like 50ms? Answer: no. async only gives you throughput, it has nothing to do with &quot;faster&quot; as far as the Python interpreter &#x2F; GIL &#x2F; anything like that. If you aren&#x27;t actually spanning among dozens&#x2F;hundreds&#x2F;thousands of network connections, non-blocking IO isn&#x27;t buying you much at all over using blocking IO with threads, and of course async &#x2F; greenlets &#x2F; threads are not a prerequisite for non-blocking IO in any case (only select() is).<p>it&#x27;s nice that uvloop seems to be working on removing the terrible performance latency that out-of-the-box asyncio adds, so that&#x27;s a reason that asyncio can really be viable as a means of gaining throughput without adding lots of latency you wouldn&#x27;t get with gevent.

In October 1981, he wrote to the producers [1]:<p><i>I came to the conclusion that this indeed is not science fiction; it is not fantasy; it is exactly what Harrison said: futurism. The impact of BLADE RUNNER is simply going to be overwhelming, both on the public and on creative people -- and, I believe, _on science fiction as a field._ … Nothing that we have done, individually or collectively, matches BLADE RUNNER. This is not escapism; it is super realism, so gritty and detailed and authentic and goddam convincing that, well, after the segment I found my normal present-day &quot;reality&quot; pallid by comparison. What I am saying is that all of you collectively may have created a unique new form of graphic, artistic expression, never before seen. And, I think, BLADE RUNNER is going to revolutionize our conceptions of what science fiction is and, more, _can_ be.</i><p><i>… As for my own role in the BLADE RUNNER project, I can only say that I did not know that a work of mine or a set of ideas of mine could be escalated into such stunning dimensions. My life and creative work are justified and completed by BLADE RUNNER. Thank you...and it is going to be one hell of a commercial success. It will prove invincible.</i><p>[1] Philip K.

You have to pay real money to get illiquid stock in a company that might easily fail. If the paper value of the stock is high, owing to recent funding rounds, you will have to pay ordinary income tax on the spread between your exercise price and the then fair market value. If you have ISOs, you may avoid ordinary income tax but may easily get hit with AMT. After you pay for the stock, and any associated taxes, you hold common shares that stand in the back of the line on any liquidity event, meaning that you might get nothing even in a liquidity event should the proceeds not exceed the value of the liquidation preferences held by preferred stockholders or should the acquisition be structured in a way that primarily rewards those who get bonus/retention packages with the acquirer and leaves others with essentially nothing.<p>As if this all were not risk enough, Skype now comes along with a vehicle by which you lose the value even of that illiquid stock you thought you had bought - and paid for, and paid tax on, and whose value you ran the risk of losing in case the company went nowhere - at the very time when the wild success case strikes. This is the essence of a rigged game. The company fails or plods along uneventfully: it has no obligation to buy back anything from you; you took the risk and lost. The company succeeds: it has the option to rob you of your equity value by getting it all back at a strike-price cost that is a tiny fraction of its now vastly appreciated market value. This is what they call "heads I win, tails you lose."<p>This is not equity ownership. It is merely the illusion of ownership - an ownership that comes with all the risks of buying stock (the cost, the tax risk, the economic risk) and none of its benefits. As this piece points out, legally, you might be able to frame things this way and maybe this is the custom and practice in private equity deals (it can even make sense in an individually-negotiated deal with a senior executive who knowingly accepted the risks involved). But it is not legal to offer it up in materially misleading terms, which seems to have happened here. And, whether technically legal or not, no one wants to play a fool's game - once exposed as the stink bomb that it is, this particular PE ploy should hereafter die the death that it richly deserves.</text></comment> | <story><title>Skype’s Worthless Employee Stock Option Plan: Here’s Why They Did It</title><url>http://techcrunch.com/2011/06/26/skypes-worthless-employee-stock-option-plan-heres-why-they-did-it/</url></story><parent_chain></parent_chain><comment><author>patio11</author><text>I once heard some advice worth remembering from a lawyer: do not sign contracts on the basis of trust for the counter party, because they are your counter party <i>today</i>. For long-term contracts, when you actually have a dispute several years down the road, you may be dealing with a totally different set of actual people. People change jobs. Companies get bought. Cultures and personalities drift over time.<p>Your contract will not, ordinarily, adjust itself just because the guy who promised that Odious Clause X was boilerplate that would never be held against you has left the company and been replaced by Scrooge McStealYourEquity. Don't give Scrooge the opportunity. Get exactly what you expect to have happen to you written in the contract.<p>P.S. Relatedly, your discount rate is probably too low, and you probably overestimate your odds of a liquidity event <i>and</i> the upside potential. Your employers will act to encourage this.

Use existing models. The easiest is web services (mostly payed). Harder way is local install, still need a good computer<p>2. Understand how models work<p>3. General understanding where all this is going.<p>4. Being able to train or finetune existing models<p>4.1 Create some sort of framework for models generation<p>4.2 frameworks for testing, training, inference, etc..<p>5. Models design. They are very different depending on the domain. You will have to specialize if you want to get deeper.<p>6. Get AGI finally.<p>All things are different. Some require just following the news, some need coding skills, others more theory, philosophy. You can&#x27;t have it all. If you have no relevant skill the first 4 are still withing the reach. Oh, yes. You can become ethic &#x27;expert&#x27;, that&#x27;s the easiest.</text></comment> |

On the one hand WhatsApp probably have more people working on the app and likely more security people too. On the other hand they may be pushed to add more features and having lots of code churn may introduce security holes.<p>3. How much work will be put into exploiting each app. On the one hand more people use WhatsApp but on the other, I guess security conscious people may be more likely to use signal.<p>A known exploit to WhatsApp happened due to 2 with a bug in how audio calls were initiated. I don’t really have a good guess as to how the apps compare on points 2 and 3 but I guess WhatsApp loses on 1.

Have fun with all the mocks.</text></comment> | <story><title>SQL databases come up with algorithms you’d never have dreamed of (2017) [video]</title><url>https://www.youtube.com/watch?v=wTPGW1PNy_Y</url></story><parent_chain><item><author>ak39</author><text>So in 20 years we&#x27;ve gone from vilifying SQL statements in code, witch-hunted folks who did this and instead invented and propped up clunky ORM implementations, ignored sage advice on the famous &quot;object-relational impedance mismatch&quot; (which the author claims he doesn&#x27;t &quot;believe&quot; exists - it&#x27;s not a choice btw) and now, after 20 years of agent orange in the bloody Vietnam of Computer Science, we are presenting why SQL was better all along - showing off windowing functions as examples? This is irony that took 20 years to sink in.<p>Am I understanding this guy&#x27;s presentation correctly? (I left around the 20 min mark of the 50 min presentation).</text></item></parent_chain><comment><author>thegeomaster</author><text>Recently I tried using an ORM &quot;properly&quot; for a bigger application. I tried for days to fix the performance problems, which were mainly caused by serialization&#x2F;deserialization overhead because of humongous generated queries where I didn&#x27;t need 90% of the info.<p>I finally gave up, and now most of the ORM usage in the codebase is just to communicate my custom queries to the underlying database and translate to&#x2F;from domain entities. I feel like this is the sweet spot―give me a thin abstraction over SQL and do the gruntwork of converting domain entities to tables and vice-versa, but nothing else, thanks.<p>I&#x27;m still unhappy about the performance (when everything is in the working set, query takes 2ms and returns a couple of rows but the whole API call, which doesn&#x27;t do much except massage the response to some kind of JSON, takes 30ms!), but that&#x27;s on me for my ORM&#x2F;language&#x2F;runtime choice, I suppose.</text></comment> |

When studying physics I found that the lectures were incredibly useful, because it&#x27;s quite hard to get in the &quot;zone&quot; of understanding the derivation being discussed when at home. However, with mathematics subjects the textbook was almost always a much better learning tool, because the derivation did not require a discussion of the physics that justified said derivation. Computer Science lectures were almost unilaterally a waste of time.</text></comment> | <story><title>Laptops Are Great, But Not During a Lecture or a Meeting</title><url>https://www.nytimes.com/2017/11/22/business/laptops-not-during-lecture-or-meeting.html</url></story><parent_chain><item><author>retrac98</author><text>To be honest, I found lectures to be a complete waste of time at University, with or without a laptop.

You could just download the lecturer&#x27;s slides and speaker notes outside of class and learn the material ahead of exams&#x2F;coursework.</i><p>This was very much my experience too. My first foray to university was the traditional full time format. I really didn&#x27;t get on well with the lectures - it felt too slow in some cases, too fleeting in others and beyond a few particular classes, not very illuminating at all. For what it&#x27;s worth this was at Imperial so I guess a &quot;top&quot; uni.<p>In later life, I did a degree with the Open University which has no lectures at all (well almost, there&#x27;s a few online and night schools but they are more like practicals than lectures). Instead it&#x27;s all self-study from guidebooks and notes with regularly graded coursework which for many of the courses is a pre-requisite to pass the examinations. I greatly preferred the latter option and felt I had a much better understanding of the material.<p>It&#x27;s been mentioned elsewhere on this thread, but audio&#x2F;video recordings are a different ballgame all together for me. I actually really like lectures in that way. I guess it all boils down to the idea of tailored, self-service. I can review&#x2F;pause&#x2F;skip and repeat at my leisure.</text></comment> |

And let&#x27;s not forget surge pricing. Or people living, or wanting to get to a place, along low-profit routes. Or people with disabilities.<p>You can always take a regular cab. Low profit routes were pretty much impossible to get pre-Uber. I am almost certain that Uber is more likely to obey disability laws than &quot;Joe&#x27;s taxi&quot; with a few cars.<p>&gt; Depends. Regular taxis tended to cost a bit more, but had much lower variance.<p>My experience with cabs is calling a dispatcher while in route and getting a price. I was charged $30 for a two mile trip to the train station before. No reasoning. Also they were much less likely to pick up minority passengers, or people in poorer neighborhoods. Also &quot;credit card machine was broken&quot; very often. Also you don&#x27;t know the route the driver will take. I guess my experience with cabs pre-Uber was different from yours, but it was incredibly high variance.<p>&gt; That seems implausible at best.<p>Many places you had a gatekeeper. You can&#x27;t just ride a taxi, and would have to purchase a medallion or sign on to an existing vendor where there&#x27;s much less competition.

In additions to all the economic gains you talk about it has saved thousands of lives a year due to less drunk driving. Additionally, it has enabled millions of people in cities to skip buying a new car&#x2F;any car which saves tons of emissions.<p>More predictable as in you know the fair before you get in. I did have to take a taxi in Los Angeles from the airport earlier this year and the guy wouldn&#x27;t tell me how much it would cost. Gave me a ballpark that was $22 less than what it ended up being.</text></comment> |
