Ignoring for a moment the cache link (I’m not sure how many people use it, maybe it’s worth testing whether Google could do with it being a bit more hidden) Google’s results page is very sparse and only provides truly useful tools.<p>I use Google’s ability to search for links from a specific time frame all the time, for example. I couldn’t do without it, it’s also accessible and minimalist. I also quite often switch between the different kinds of links I can search for.<p>I don’t see much on the results page one could reasonably remove. Exposing some of the advanced search options in the UI was the right step for Google to take. They didn’t pick everything, only the most important stuff.

Paper packaging is much more fragile than plastic packaging. Boxes permanently dent, buckle when compressed, tear much more easily, etc, when enduring punishment that a plastic container will shrug off. Paper is also much less resistant to water damage. Paper-packaged products like milk cartons or juice boxes are usually transported in durable, rigid-walled crates, and would probably do much worse than the previous plastic bottle in a regular door-delivery use-case.<p>2. I&#x27;ve always found the relatively low rigidity of the whole assemblage to make sipping directly from a TetraPak sort-of-thing a little slippery and uneasy. The box can warp in all sorts of ways. Maybe I&#x27;ve just been burned by spilling milk on my shirt late at night trying to drink from the carton...<p>3. Bag-in-box specifically doesn&#x27;t &quot;scale down&quot; to single servings that well. The experience of drinking out of a bladder within a larger box is less-than-ideal because the bladder can slosh around inside the container. Maybe if they aimed to sell bulk wet Soylent fluid, bag-in-box would be the way to go.</text></comment> | <story><title>Designing a Bottle</title><url>http://blog.soylent.com/post/163186012757/how-to-design-a-bottle</url></story><parent_chain><item><author>ethagknight</author><text>Wouldn&#x27;t a Boxed Soylent (sealed bladder in a box like boxed wine) be most efficient for shipping to consumer, and most efficient for consumption?

I can also do &quot;Alexa, turn off living room light one&quot; to just turn off a particular light.
One thing that I&#x27;ve noticed with Alexa and Home Assistant is that I have an outlet labeled &quot;Xmas Light&quot; and I can either say &quot;Alexa, turn on Xmas Light&quot; or &quot;Alexa, turn on Christmas tree light&quot; and it seems to discern between the two.<p>Overall I love this combo and is working pretty dang good.<p>Next goal is to use PIR sensors so when I go to the basement it&#x27;ll automatically turn on the basement lights.</text></comment> | <story><title>Raspberry Pi 3 based home automation with Node.js and React Native</title><url>https://github.com/deepsyx/home-automation</url></story><parent_chain><item><author>redsummer</author><text>I managed to get bilingual voice activation (Alexa and Siri&#x2F;HomeKit - maybe Google Home in future) working with Home Assistant, homebridge, pi-mote, raspberry pi 3 and four energenie sockets.

After a BS and now almost a MS in computer engineering I think I could (...eventually) pull something like this off, but this guy clearly spent a lot of time and effort on learning the ins and outs of computer architecture on his own, in high school no less.<p>To those complaining that this could be done on a fpga in verilog or something, I think that might be kind of missing the point. There is just something about building the logic up from the ground that is very satisfying. Hooking up the physical wires makes it all that much more real. A huge time investment, but i got the feeling the kid spent a good deal of his free time on it.<p>So again, mad props.

It&#x27;s increasingly hard to find a version of a product that&#x27;s <i>not</i> low-quality garbage - the expensive option is often just the cheap option with extra markup for those who got fooled by marketing, or naively believe companies still care about their brands.<p>That&#x27;s the unexpected side effect that, I feel, people <i>still</i> mostly failed to realize: because running a company and manufacturing anything has nontrivial costs, letting the market race to the bottom hollows out the middle. You&#x27;re left with a bunch of specialty vendors who make quality goods for other businesses or governments, at ridiculous prices, and the low-quality throwaway garbage for everyone else. The &quot;more expensive, reasonable quality&quot; product group disappears - the vendors move either into low-quality crap or too-expensive-for-individuals specialty items (or sometimes both), as the middle can&#x27;t compete with either end.<p>I imagine the threat of AI-generated content to be similar: as it completely blows the bottom across creative industry, it will hollow it out. Skilled creators will, when they can, move to the high-end Big Art, where you pay more for the work&#x27;s provenance than for the enjoyment itself, because they won&#x27;t be able to afford competing with somewhat worse but <i>much cheaper</i> AI-generated shovel-art.<p>(Also relevant is that regular people are usually as good at distinguishing between crap and good products as they&#x27;re at distinguishing between crap and good art.)</text></comment> | <story><title>Drowning in AI Generated Garbage: the silent war we are fighting</title><url>https://ploum.net/2022-12-05-drowning-in-ai-generated-garbage.html</url></story><parent_chain><item><author>tylerrobinson</author><text>I see parallels here with industrialization and automation in manufacturing and food production.

The problem can be solved.<p>On the Intel 8086, every address has 4096 ways of referring to it by some combination of segment:offset. A segment is 64 kilobytes wide, and the segment: part of the address is &quot;paragraph&quot; (16 byte block) aligned. 65536&#x2F;16 = 4096. For instance address 0x1234 can be referenced as 0123:0004, or 0122:0014 and so on.<p>However, there <i>is</i> a unique underlying address.<p>A pointer value can be normalized (using nonportable code, of course) to use, say, the largest possible segment value and the smallest possible offset. The resulting value can then be hashed.<p>Another way to deal with it on 8086 might be to use a &quot;far&quot; pointer, and calculate its offset from a &quot;far&quot; null pointer:<p><pre><code> (far char *) ptr - (far char *) 0;
</code></pre>
This should produce the physical address as an integer.<p>So that is to say, the concept of hashing an address is sound; only using &quot;pointer&quot; to mean &quot;address&quot; is not maximally portable. An implementation of pointer hashing can be ported to such architectures by some nonportable code, if necessary.<p>If you care about such portability, wrap the &quot;pointer to integer address&quot; logic in a function and implement that function as necessary.</text></comment> | <story><title>You Can't Always Hash Pointers in C</title><url>http://nullprogram.com/blog/2016/05/30/</url></story><parent_chain></parent_chain><comment><author>gpderetta</author><text>Some motorola 68000 machines did automatically mask out some of the most significant bits of any pointers. This means that two pointers to the same object can have different representation. That did happen in practice as programmers used the highest bits to stuff metadata and relied on the automatic masking. That made things interesting when the platform wanted to increase the address space. And preventing this sort of backward compatiblity issue is the reason why AMD64 will trap if the unused bits of the address space are not all 1 or 0.<p>Bottom line, the pointer to integer conversion should be specified by your platform ABI. Read it, then either refuse to support your program on platforms with insane ABIs or have a fallback path for them.</text></comment> |

Even in products which ostensibly do want their users to develop expertise without being advertisement driven, such as Excel, Powerpoint or Word.

Also, if you guess wrong and a popular flight did not fill up -- you have to take the flights!</text></comment> |

The whole piece has as its backdrop the development of Fetchmail, which is not a well-regarded piece of software.<p>What&#x27;s notable about Cathedral is its timing; it did capture the zeitgeist of what was an important moment in the computing field, the moment where we transitioned from 386bsd-style hobby projects to an industry run on free and open source software. But Raymond isn&#x27;t the reason why any of that happened, and much of his description of that moment is faulty; the rest of it is just a retrospective of the engineering decisions involved in the writing of a midlist mail processing utility (fetchmailrc syntax, password encryption, the now-largely-irrelevant distinctions between MDAs and MTAs).<p>Even the high-level organizing notion of &quot;cathedrals&quot; and &quot;bazaars&quot;, which should have been a lay-up, hasn&#x27;t really proven out.</text></comment> | <story><title>The Cathedral and the Bazaar (1999)</title><url>http://www.catb.org/~esr/writings/cathedral-bazaar/cathedral-bazaar/</url></story><parent_chain></parent_chain><comment><author>dang</author><text>Related (surprisingly little over the years) - others?<p><i>The Cathedral and the Bazaar (1999)</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=35829361" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=35829361</a> - May 2023 (2 comments)<p><i>On Management and the Maginot Line</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=33314682" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=33314682</a> - Oct 2022 (27 comments)<p><i>The Cathedral and the Bazaar</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16328219" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=16328219</a> - Feb 2018 (1 comment)<p><i>The Cathedral and the Bazaar (2000)</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=12198625" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=12198625</a> - July 2016 (1 comment)<p><i>Eric Raymond&#x27;s &#x27;The Cathedral and the Bazaar&#x27; Turns 19</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11754279" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11754279</a> - May 2016 (57 comments)<p><i>Revisiting the many eyes theory</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=8416597" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=8416597</a> - Oct 2014 (1 comment)<p><i>A Second look at the Cathedral and the Bazaar (1999)</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=1222945" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=1222945</a> - March 2010 (1 comment)<p><i>The Cathedral and the Bazaar</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=162376" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=162376</a> - April 2008 (2 comments)</text></comment> |

Those are much more common than people realize.<p>As an example, in a recent case that I'm familiar with in Oregon, a man that I personally know was unjustly charged with 4 criminal charges that the DA knew were unjustified. He fought. He won. He now has, in addition to a crushing legal bill, a bill for the time he spent locked up in prison on trumped up charges?<p>Why did this happen? Various reasons. When bf unexpectedly comes home to find his gf having sex with the husband of the house that they're house surfing at, the upset bf can get the gf to make up a rape case. (The guy shouldn't have been having the affair, but it wasn't rape.) When said husband is a Native American in a rural area, the DA knows that given racism and the fact that the guy was doing something dislikable, there is a reasonable chance of winning no matter what the facts happen to be.<p>But in my opinion the biggest single factor is that the DA in question is an investor in the private jail to which he sends people. When the DA can use the powers of the state to send people to prison, and PERSONALLY PROFITS from this, abuse of power is only to be expected. And even when the DA loses - as in this case - the prison still gets paid. And if the bill doesn't get paid, care to guess whether a hard line will be taken...?<p>I have no idea how widespread this type of conflict of interest is. I suspect that it is much more widespread than most people think (because the people who run private jails are well aware that getting the DA on board generates profits). But as long as it mostly impacts poor people that nobody cares about, it won't be a political issue.</text></comment> | <story><title>Teenager facing terrorism charges for something he posted on Facebook</title><url>http://cms.fightforthefuture.org/teenager/</url><text></text></story><parent_chain></parent_chain><comment><author>mintplant</author><text>&#62; "(Expletive) a boston bominb wait till u see the (expletive) I do, I’ma be famous"<p>&#62; The actual line is:<p>&#62; "(Expletive) a boston bominb wait till u see the (expletive) I do, I’ma be famous <i>rapping</i>"<p><a href="http://bostonherald.com/news_opinion/local_coverage/2013/05/teen_methuen_rapper_held_without_bail_for_facebook_bomb_threat" rel="nofollow">http://bostonherald.com/news_opinion/local_coverage/2013/05/...</a><p>&#62; An accused teenage rapper pleaded not guilty today to making a bomb threat on Facebook he warned <i>would eclipse the horror of the Boston Marathon tragedy and make him “famous.”</i><p>That's absolutely disgusting.

I think the last time I touched anyone was when I hugged my mom when she visited me 3 months ago, and before that I don&#x27;t think I touched anyone for the 6 months since I broke up with my gf.<p>After finishing college I moved to basically the middle of nowhere for my tech job without knowing anyone in the area. Wasn&#x27;t proactive enough making friends, and because of my gf at the time I didn&#x27;t seek out any women. We broke up right as the pandemic started, which may have been the worst possible time.<p>I&#x27;m not sure if it&#x27;s because it&#x27;s been so long that I touched anyone, but I don&#x27;t get touch deprived as often as I would have expected. Sure there are times occasionally where I feel really lonely, but so far it&#x27;s been pretty easy to brush that off. However, taking care of my mental health has been nearly a full time job. I make sure to exercise daily, I picked up guitar and mountain biking, and I blocked all social media I see as toxic (reddit, youtube, facebook. HN is okay in moderation). I my sleep schedule in check with targeted melatonin and bluelight filters. Keeping up with old friends and family is also essential.<p>My running theory is that touch is certainly a positive, but it isn&#x27;t essential if the other parts of your life are kept in shape. Although shortening that list of mental health tasks to something more manageable does sound enticing. I&#x27;ve never been good at dating though, and with the double whammy of it being quarantine and not having a local friend group I&#x27;m not really sure how to solve that problem. Dating advice might be a bit off topic for HN though, considering temporarily unblocking reddit.</text></comment> | <story><title>The Need for Touch</title><url>https://aeon.co/essays/touch-is-a-language-we-cannot-afford-to-forget</url></story><parent_chain><item><author>nxc18</author><text>I don&#x27;t know how common this is, but I was raised to see intimate touch as reserved exclusively for family and sexual&#x2F;romantic partners.

I&#x27;m mostly not.<p>First I don&#x27;t want to catch something (aids, chlamydia, herpes, ...) so a few minutes of sex doesn&#x27;t seem worth the risk. I know, at least according to popular media that puts me in the minority. If my attitude is common it&#x27;s probably not easy to spot.<p>Second, I don&#x27;t want to hurt people. I know they exist but 9 times out of 10 people I meet want a serious relationship and would be hurt if we slept together than then I called it quits. I wouldn&#x27;t lie to them directly but they&#x27;d feel like I was lying to them if I say, slept with them 2-3 times and then stopped seeing them. So, I basically don&#x27;t get into it in the first place unless I believe that I&#x27;d like to be with them longer term. Of those people that could be more casual usually issue 1 comes up. They sleep around so they are more likely to have something and plus I don&#x27;t want my heart broken.<p>Third, I&#x27;m also someone who just wants one person not just for sex but for love and companionship so my attitude is bad when meeting &#x2F; looking for people. My attitude is &quot;can I see myself being with this person long term&quot; instead of &quot;would it be fun to be with this person for the moment&quot;. That answer is quite often &quot;no, I can&#x27;t see myself being with this person long term&quot;. I don&#x27;t think that&#x27;s that strange of a thought. A stereotype of a story is the person that doesn&#x27;t think this way and has lots of failed relationships for choosing superficial qualities of attractiveness as their reason for getting into a relationship. But, at least they had a relationship.<p>Anyway, the sum of those 3 things and possibly some bad luck being in jobs which have few members of the opposite sex and friends that have few friends of the opposite sex means I haven&#x27;t had a relationship for ~17 years. I hope every day that will change, I frequent 5 dating sites. I have matches. But getting something started seems really hard. I would do much better if I went to church (I&#x27;m atheist) or did some activity where I got to know people over time and become friends first. I&#x27;ve gone to several meetups but if they are truly about something I care about they usually have few members of the opposite sex. I&#x27;ve been to a few otherwise but it&#x27;s been the same bad luck I guess. No one I&#x27;m interested in or no one that shows interest.</text></comment> |

The degree of diplomacy varies, but there aren&#x27;t many NATO members in that region who are as compatible when it comes to diplomatic ties with the region&#x27;s powers. Russia, unfortunately doesn&#x27;t deal with Iran, Israel and the Saudis the same way.<p>Given their growing business ties and influence in the region, maybe China can be another powerful ally. Or India. It certainly would help to have more than one dependable ally there, but China, like Russia, is in a weird power-play game with the USA, Australia, etc. Russia is more biased than Turkey, and that says a lot since Turkey cannot be a neutral Switzerland type because of their borders and demographic, so they&#x27;re less of an option.<p>Also, let&#x27;s not forget that Turkey has better relations with some ex-USSR nation that have considerable natural resources, due to cultural heritage, but then again strained relations with most of the ex-USSR countries.<p>It&#x27;s a mess, but that&#x27;s world politics.</text></comment> | <story><title>The H-Bombs in Turkey</title><url>http://www.newyorker.com/news/news-desk/the-h-bombs-in-turkey</url></story><parent_chain></parent_chain><comment><author>mikeash</author><text>I&#x27;m skeptical that the PALs are as easy to bypass as this article says.

So if you start your design from trying to determine ADTs instead of trying to work out the kinds of message conversations that need to go on you end up with mess of types.<p>In the wizards and warriors we see a large amount of modelling of a domain with rules. But we, even at the end, still have little idea of what messaging is going to be going on, there is a hint about attacking werewolves. But we&#x27;ve already made a lot of assumptions about what our first class entites are. Often what can happen is we find, while we thought we modelled it ok and even sorted out a rule based system, it still seems difficult for our objects to have conversations.<p>maybe what would be better is some thing that can attack other things and wizards, weapons, and warriors are all simply modelled by some composable set of stat modifiers.</text></comment> | <story><title>How I Learned to Stop Worrying and Love the State Machine</title><url>http://raganwald.com/2018/02/23/forde.html</url></story><parent_chain><item><author>hprotagonist</author><text>Eric Lippert&#x27;s &quot;Wizards and Warriors&quot; blog posts seem appropriate here, especially as an example of how tracking state and OO can clash pretty badly.<p><i>A common problem I see in object-oriented design is:<p>A wizard is a kind of player.<p>A warrior is a kind of player.<p>A staff is a kind of weapon.<p>A sword is a kind of weapon.<p>A player has a weapon.<p>But before we get into the details, I just want to point out that I am not really talking about anything specific to the fantasy RPG genre here.

One little rule I&#x27;ve stumbled onto over the years that this series revolves around is:<p><i>When I&#x27;m stuck on a software design problem, pick some random part of the program and see what happens if I make it first class.</i><p>In this case, Eric takes the game rules and turns them into objects. (Essentially the Command pattern[1], which is close to my heart[2].)<p>You can go overboard with this, of course, but I&#x27;ve found time and again if it seems like I can&#x27;t get my code to hang together, it&#x27;s usually because I&#x27;m missing a noun — a reification of some part of my problem that I can pass around and do stuff with.<p>[1]: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Command_pattern" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Command_pattern</a><p>[2]: <a href="http:&#x2F;&#x2F;gameprogrammingpatterns.com&#x2F;command.html" rel="nofollow">http:&#x2F;&#x2F;gameprogrammingpatterns.com&#x2F;command.html</a><p>PS: Another solution to Eric&#x27;s initial problem with warriors, wizards, swords, and staves is to be more precise about what capability Player has. If Warriors can only wield Swords and Wizards can only wield Staves, then it&#x27;s <i>not</i> the case that Player&#x27;s Weapon field can be set with any weapon.<p>So one option is to make Weapon an abstract getter in Player. Then add setters and fields in Wizard and Warrior for the specific types. If all you have is a Player, you can see what their wielding, but not change it. Then, to wield something, you need to know what kind of player you&#x27;re dealing with first.<p>Of course, that doesn&#x27;t scale very well to lots and lots of business rules as in later in the series. But it works if you have a relatively small number of constraints in your subclasses — you just push them up such that the superclass API only exposes the intersection of all of the subclasses&#x27; allowed operations.</text></comment> |

Rather, it was a &quot;modest proposal&quot; in the tradition of Swift, in which the actual call to action was for the field to be more critical of papers, especially to be on the lookout for all fraud, both the obvious kind and the more subtle variants, the latter of which also do great damage to the field.<p>The tip: humor like this is fun and appreciated by people who run in the same circles as the author, but an essay like this will be read by a diverse cross-section of people. Some won&#x27;t have the cultural references, some won&#x27;t have English as a first language, etc. Almost always when I&#x27;ve snuck jokes into my writing, I&#x27;ve found it causes confusion.<p>So I might have written this a slightly different way, something along the lines of: the community is structurally more equipped to deal with blatant than subtle fraud. Ironically, now that we&#x27;re seeing more egregious examples of fraud, there&#x27;s a better chance that things will get better; we would have tolerated the subtle types for a long time, as lots of people benefit from the status quo.<p>If the author were actually legitimately calling for more fraud, then I apologize for misunderstanding.</text></comment> | <story><title>Please commit more blatant academic fraud</title><url>https://jacobbuckman.com/2021-05-29-please-commit-more-blatant-academic-fraud/</url></story><parent_chain><item><author>tlb</author><text>The idea that a field can be reformed by making it worse until it suddenly faces a reckoning and emerges much better is ...

This would help greatly with the kinds of issues that are being discussed:<p>- It would be much harder to hide makeup results and cherry-picked seeds<p>- Useless research would not be as easy to hide<p>- The real-world impact of the research would be more valued.<p>- Researchers would be forced to recheck their code for it to be presentable, which could be a net benefit in terms of finding mistakes<p>- and so on..<p>I do imagine this could harm the number of replications of the research.
However, I think there can be a net positive effect from such a policy. What do you think?</text></comment> |

Though they might not even be able to do that, because the law-enforcement skills to match typewriter documents to each other have also probably nearly completely atrophied.<p>You&#x27;re probably more likely to be caught by being the weirdo still buying typewriter ribbons.</text></comment> | <story><title>EU Commission doesn't understand what's written in its own chat control bill</title><url>https://mullvad.net/en/blog/2023/3/28/the-european-commission-does-not-understand-what-is-written-in-its-own-chat-control-bill/</url></story><parent_chain><item><author>jll29</author><text>Don&#x27;t believe vendors&#x27; lies about &quot;end-to-end&quot; encryption.<p>If caught red handed, they will always say it depends on how you define where both &quot;ends&quot; begin.<p>Do not trust a cloud service that you have not developed and deployed yourself.<p>You may trust untrusted hardware with your encrypted content, but only if you have given it your content pre-encrypted by yourself, not trusted a third party to encrypt it on your behalf.

This is definitely getting better, but the number of hours still seems high to me. As a developer, I&#x27;m strongly against extended hours because I know how quickly the error rate creeps up. (And I probably wouldn&#x27;t know that if I weren&#x27;t doing TDD and pair programming, because the first thing that goes for me is ability to notice my poor performance.) My basic question was: shouldn&#x27;t doctors work 8 hours and then go home?<p>The big difference between writing code and doing medicine is that patients won&#x27;t stay the same when a doctor leaves for the day. With 8-hour shifts and 40-hour weeks, covering a patient around the clock requires 4-5 people. Those people will have 21 handoffs during that week. Each one of those handoffs is an opportunity for information to get lost, for understanding to fade, for followups not to happen. If people work 12 hours, that&#x27;s only 4 handoffs. 16 and it&#x27;s 10. 24 and it&#x27;s 7.<p>Obviously, at some point the harm from overwork outweighs the harm from handoffs. But it&#x27;s not an easy decision to make. When I&#x27;m debugging some weird, urgent problem, I know how valuable it is to stay with it, to keep all the state loaded in my head until I figure it out. And hospitals are full of weird, urgent problems.</text></comment> | <story><title>75% of med students are on antidepressants, stimulants, or both?

More handoffs = more errors. My wife is a resident and she supports 30 hour shifts for residents for this reason.

How do you reconcile that sentence?<p>The fact that something is done in public does not mean that it is centralized. There is public and decentralized, public and centralized, private and centralized, and private and decentralized.<p>Decentralization itself, is a spectrum and not a binary quality. Just as, I assume, public &#x2F; private also falls on some sort of spectrum spanning from everyone in the world being able to see to VISA&#x2F;Mastercard corporate privacy policy to national intelligence agencies to group or individual privacy.<p>It is completely possible to conduct transactions privately on blockchains. Monero and z-cash (using zero knowledge proofs) are the best examples of this.<p>The biggest blockchains choose not to either due to legacy design choices (zero knowledge systems are a recent innovation) or the benefits of openness. For example, public transaction history allows for development of an on-chain reputation for a pseudo-anonymous account. It&#x27;s also quite useful for managing decentralized organizations, as the treasury and spending records is meant to be public to keep the DAO accountable to its members and prospective members.<p>With the recent introduction of zk rollups on Ethereum, it&#x27;s now possible to have the best of both worlds, in my opinion (see <a href="https:&#x2F;&#x2F;aztec.network&#x2F;index.html" rel="nofollow">https:&#x2F;&#x2F;aztec.network&#x2F;index.html</a>). Transactions that need to be private will be conducted on zero-knowledge rollups built for privacy. Mastercard is working on this with Consensys for Ethereum (<a href="https:&#x2F;&#x2F;www.coindesk.com&#x2F;business&#x2F;2021&#x2F;12&#x2F;16&#x2F;consensys-collaborates-with-mastercard-on-new-ethereum-scaling-solution&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.coindesk.com&#x2F;business&#x2F;2021&#x2F;12&#x2F;16&#x2F;consensys-colla...</a>).</text></comment> |

The core concepts are easy to understand and compared to other frameworks lean. JSX is easy, components are trivial but once you try to get productive, wow, it&#x27;s not that simple anymore. It&#x27;s more than a bit of HTML embedded in JS.<p>So, you need really to spend time to understand the core of React <i>very, very well</i>. And this takes time, effort and at least a couple of real and serious apps you should write to understand why React and its concept are the next step in FE dev and why others use React&#x27;s concept as blueprint (e.g. Inferno). Tutorials are not enough, real projects are the best way to grok React.<p>I don&#x27;t think it&#x27;s like Java Swing, not at all (I think the comparison is misleading since React is from the ground very different, e.g. totally different design patterns&#x2F;paradigms, .g. no observer pattern, and a super minimal API). It&#x27;s a tool which is super flexible. It&#x27;s definitely not your daddy&#x27;s jQuery-based front-end framework which let you start quickly. But once you get more experienced with React you face much better code maintainability with a small code base already. Further, you should be good at JS <i>and</i> ES6. I guess this might be another obstacle for many. Compared to Vue which I like a lot and which shares also some similarities, Vue is more complex due to a large API surface, code-in-HTML templating syntax, nested instance semantics, observable gotchas, ES5 workarounds and a larger documentation that is absolutely vital to read and understand.<p>Give React a try. You need of course a real use case. Many website&#x27;s use cases don&#x27;t require React and could be done with some simple server-side rendering. So, React is def not the best tool of every job.<p>I was ignoring React too long by just using it for some toy projects or going through tutorials. This was not enough. Once I tried React for a real project, I learned its brilliance and I don&#x27;t want to go back to anything else for SPAs or websites with more interactivity.</text></comment> | <story><title>Show HN: Read Hacker News Like Pinterest – Built with Vuejs</title><url>https://hnews.xyz/new</url></story><parent_chain><item><author>brilliantcode</author><text>The more I am studying React + Redux, the more it becomes apparent to me that it&#x27;s over engineered for an individual and even a small team.

The answer is, it retries twice and then you can have it go to a deadletter queue. If you want to have any configuration control over your retry or deadletter behavior, SQS is really handy.<p>It&#x27;s also a useful pattern to, instead of configuring the SQS event itself as your Lambda trigger, have a scheduled trigger and then perform health checks on your service dependencies before pulling messages from the queue. This technique saves you wasted retries and even gives you more fine-grained control over deleting messages (the SQS mechanism for saying, &quot;this is done and you don&#x27;t need to retry it after the timeout). The SQS trigger, in contrast, deletes the entire batch of messages if the Lambda exits cleanly and does not delete any of them if the Lambda does not exit cleanly, which is a bit messy.<p>Also, you can have an SQS queue subscribe to multiple SNS topics, which means you can set up separate SNS topics for backfill or other use cases. This is especially useful in cross-account use cases, where often your online events are coming from an SNS from a different account, but you want to be able to inject your own testing and backfill events.</text></comment> | <story><title>New for AWS Lambda: Use Any Programming Language and Share Common Components</title><url>https://aws.amazon.com/blogs/aws/new-for-aws-lambda-use-any-programming-language-and-share-common-components/</url></story><parent_chain><item><author>otterley</author><text>No need to use SQS here, assuming you don&#x27;t need strict ordering behavior, since SNS can use Lambda functions as notification targets.

I think the mail system is exceptionally well-functioning. It's a massively-scalable, decentralized, asynchronous messaging system that supports large file attachments. At this, it excels. There's not one big evil company controlling all messages and unless you're sending massive amounts of emails every day, your messages almost always end up exactly where they're supposed to. I'd challenge anybody to do better.<p>The author's main gripe is Mailer Daemon messages. It's not <i>email's</i> fault that people write shitty clients that don't display a pretty failure message. If your car doesn't have anti-lock breaks, it's not the road's fault when you hit a patch of ice and slam into a tree.<p>Email is great not only because it works simply and beautifully, but because it's so extendable. People think it's broken. It's not. It's just simple...and it's this same simplicity that makes it easy to build on top of. Look at Gmail or Xobni. Both have incredible features that "email" doesn't have because they took the time to build extras on top that make it work nicely.<p>Email is NOT broken. There's nothing to fix. Whatever fixes you think it needs <i>you can make yourself</i>. The underlying platform works great. If you have a problem, write/patch a client.</text></comment> | <story><title>This is the mail system</title><url>http://dewith.com/2012/this-is-the-mail-system/</url></story><parent_chain></parent_chain><comment><author>dsr_</author><text>Hi.

Topics and queues with different segmentation features are much more powerful and fine-grained in control compared to a service that&#x27;s tied to HTTP transport than, say, a REST or SOAP API. For object serialization &#x2F; marshaling, you can use a lot more stuff now all of a sudden like Protocol Buffers, Capn Proto, Thrift, Avro. The recommended advice comes down to what your bus &#x2F; queue is (each one offers vastly different best practices and features to implement them) as well as how you want to scale out and up. But perhaps a general set of terminologies &#x2F; jargon may be worth pursuing as a community for the problem.<p>The question I really have is how people have managed to upgrade their message bus and to keep availability high with rollback contingencies while upgrading, say, RabbitMQ or Kafka across all your connected services.

If we have a good idea and a poor implementation, then the correct response is to fix the implementation, not throw out the whole idea as fundamentally broken.<p>Unfortunately, there&#x27;s also not much that the CAs can do to fix this by themselves. If we want to have a digital representation of a legal entity&#x27;s identity, the best way to do that is to have a first-class digital identity rather than the hack of a system we have today which attempts to create a poorly supported, non-portable identity on the basis of emailed paperwork and phone calls. Such a first class identity - with private keys controlled by the legal entity, entrusted to the entity when it was first created - will allow clients to verify the identity against the <i>source which actually governs it</i>.<p>I can understand the privacy concerns surrounding the creation of legal digital personal identities - the creation of a definitive population ledger that goes along with it etc. But for <i>companies</i>? That the US doesn&#x27;t have such a solution for companies in this day and age is just myopic.</text></comment> |

Puppet suffers hugely from the influence from the fact that ordering is unpredictable and that you have to use arrows or requires to add order. People accidentally forget to add ordering, the resulting code works most of the time, and then one day you start running into an issue because some implicit dependency either didn&#x27;t happen, or happened in the wrong order. In as much as all logic programming involves not explicitly controlling flow, I think they&#x27;re inappropriate for configuration management. Sadly, I&#x27;m still stuck with using Puppet because of the organisation I work in.<p>Having worked with Prolog in the past, I would also suggest that an important feature of a configuration management language is that the syntax make it hard to make typos and other minor errors because the feedback loop of deploying your code against a local vagrant machine is already long enough. I vividly remember the annoyance of having missed the full stop to end a block. I&#x27;m not desperate to repeat that experience.</text></comment> | <story><title>Marelle: logic programming for devops</title><url>http://quietlyamused.org/blog/2013/11/09/marelle-for-devops/</url></story><parent_chain></parent_chain><comment><author>mickeyp</author><text>Prolog&#x27;s a surprisingly good fit for many every-day tasks where people otherwise invent DSLs or poorly-defined state machines and pattern matching algorithms.<p>So how come we don&#x27;t use it more often? Well, the reason is actually quite simple:<p>Prolog&#x27;s incredibly difficult to reason about once you grow past trivial facts and clauses like in the OP&#x27;s article -- the examples given by him would&#x27;ve been introduced to you in the first lesson on Prolog in, say, University. The complexities of green&#x2F;red cuts, backtracking and the procedural nature of Prolog makes it a really difficult language to truly learn -- much less one to specify complex programs in.<p>I&#x27;ve never programmed in a language where 5-6 lines of errant Prolog code could stump myself, a post grad and a professor before until I did Prolog.</text></comment> |

It allows staggered upgrades for people who do not want to upgrade yearly, but still create the necessary incentive for incremental improvement.<p>A new iPhone every 5 years for example, would be dumb. Ignore the hype and marketing and just pick the one you&#x27;d like if and when you upgrade.<p>A tangent:<p>Personally, I wish more things had yearly upgrades and the backwards&#x2F;forward compatibility Apple devices generally have. It&#x27;s a different model, but it would be nice if game consoles had improved iterations yearly. The once a half decade model creates too much of a boom&#x2F;bust cycle imho.

What should the compiler emit here? Should it emit a bounds check? In the event the bounds check fails, what should it do? It is only through the practice of undefined behavior that the compiler can consistently generate code that avoids the bounds check. (We don&#x27;t need it, because if `i` is out-of-bounds then it&#x27;s undefined behavior and illegal).<p>If you think this is bad, then you&#x27;re arguing against memory unsafe languages in general. A sane position is the one the Rust takes, which is by default, yes indeed you should always generate the bounds check (unless you can prove it always succeeds). But there will likely always be hot inner loops where we need to discharge the bounds checks statically. Ideally that would be done with some kind of formal reasoning support, but the industry is far that atm.<p>For a more in depth read: <a href="https:&#x2F;&#x2F;blog.regehr.org&#x2F;archives&#x2F;213" rel="nofollow">https:&#x2F;&#x2F;blog.regehr.org&#x2F;archives&#x2F;213</a></text></item><item><author>moomin</author><text>There are only two models of UB that are useful to compiler users:<p>1) This is a bad idea and refuse to compile.<p>2) Do something sensible and stable.<p>Silently fail and generate impossible to predict code is a third model that is only of use to compiler writers.

The excuse for not taking responsibility is that there are &quot;language standards&quot; saying that these bugs should be blamed on millions of programmers writing code that bumps into &quot;undefined behavior&quot;<p>But that&#x27;s not an excuse for having a bug; it&#x27;s the exact evidence that it&#x27;s not a bug at all. Calling the compiler buggy for not doing what you want when you commit Undefined Behavior is like calling dd buggy for destroying your data when you call it with the wrong arguments.</text></item></parent_chain><comment><author>opnitro</author><text>I think the &quot;do the normal&quot; thing is very easy to say and very hard to do in general. Should every case of `a &#x2F; b` inject a `(b != 0) &amp;&amp; ((a != INT_MAX &amp;&amp; b != -1))`? If that evaluates to `true` then what should the program do? Or: should the compiler assume this can&#x27;t happen. Languages with rich runtimes get around this by having an agreed upon way to signal errors, at the expense of runtime checking. An example directly stolen from the linked blog post:<p><pre><code> int stupid (int a) {
return (a+1) &gt; a;
}
</code></pre>
What should the compiler emit for this? Should it check for overflow, or should it emit the asm equivalent of `return 1`? If your answer is check for overflow: then should the compiler be forced to check for overflow every time it increments an integer in a for loop? If your answer is don&#x27;t check: then how do you explain this function behaving completely weird in the overflow case? The point I&#x27;m trying to get at is that &quot;do the obvious thing&quot; is completely dependent on context.</text></comment> | <story><title>Clang vs. Clang</title><url>https://blog.cr.yp.to/20240803-clang.html</url></story><parent_chain><item><author>Dylan16807</author><text>&gt; What should the compiler emit here?<p>It should emit an instruction to access memory location some_array + i.<p>That&#x27;s all most people that complain about optimizations on undefined behavior want.

What should the compiler emit here? Should it emit a bounds check? In the event the bounds check fails, what should it do? It is only through the practice of undefined behavior that the compiler can consistently generate code that avoids the bounds check. (We don&#x27;t need it, because if `i` is out-of-bounds then it&#x27;s undefined behavior and illegal).<p>If you think this is bad, then you&#x27;re arguing against memory unsafe languages in general. A sane position is the one the Rust takes, which is by default, yes indeed you should always generate the bounds check (unless you can prove it always succeeds). But there will likely always be hot inner loops where we need to discharge the bounds checks statically. Ideally that would be done with some kind of formal reasoning support, but the industry is far that atm.<p>For a more in depth read: <a href="https:&#x2F;&#x2F;blog.regehr.org&#x2F;archives&#x2F;213" rel="nofollow">https:&#x2F;&#x2F;blog.regehr.org&#x2F;archives&#x2F;213</a></text></item><item><author>moomin</author><text>There are only two models of UB that are useful to compiler users:<p>1) This is a bad idea and refuse to compile.<p>2) Do something sensible and stable.<p>Silently fail and generate impossible to predict code is a third model that is only of use to compiler writers. Hiding behind the spec benefits no actual user.</text></item><item><author>josephcsible</author><text>&gt; compiler writers refuse to take responsibility for the bugs they introduced, even though the compiled code worked fine before the &quot;optimizations&quot;. The excuse for not taking responsibility is that there are &quot;language standards&quot; saying that these bugs should be blamed on millions of programmers writing code that bumps into &quot;undefined behavior&quot;<p>But that&#x27;s not an excuse for having a bug; it&#x27;s the exact evidence that it&#x27;s not a bug at all. Calling the compiler buggy for not doing what you want when you commit Undefined Behavior is like calling dd buggy for destroying your data when you call it with the wrong arguments.</text></item></parent_chain><comment><author>cobbal</author><text>Ah, but what if it writes so far off the array that it messes with the contents of another variable on the stack that is currently cached in a register? Should the compiler reload that register because the out of bounds write might have updated it? Probably not, let&#x27;s just assume they didn&#x27;t mean to do that and use the in-register version. That&#x27;s taking advantage of undefined behavior to optimize a program.</text></comment> |

We lived in an apartment building in a major downtown area. My childhood memories consist of playing with other kids in the same apartment building or the neighboring buildings. These games were almost always improvised on the spot, where someone would throw out an idea and the others in the group would build upon it. There would be rule-making and negotiation, and lots of arguments. And then we would play.<p>Even when we played well-known games, they had at least some element of improvisation. For example, if we couldn&#x27;t pool enough money to buy a rubber soccer ball, we would find a soda can, crush it on the ground and use it as the ball. There would be rules with that, such as wearing close-toed shoes and keeping the can on the ground at all times (if it took into the air it became a sharp and dangerous projectile). The interesting thing is that these rules were invented on the spot by us kids. Parents had no involvement.<p>One of the major differences I noticed when I came to America for college was that, in social settings, people were utterly incapable of improvising a game from scratch. We always had to play a game that someone else had invented, such as a board game or a well-known drinking game - both of which had strict rules. And if the board game was missing a piece? It was deemed unplayable. No one tried to improvise a solution because it required outside-the-box thinking. One weekend, the guy who had all the board games went back home to visit his parents, and his door was locked. So I found a large piece of cardboard from the trashcans behind the dormitory, and some supplies, and spent an hour or so creating a board game. When I presented it to the group, people were <i>stunned</i>. We played for hours and I became the god damn hero.<p>The interesting thing is that I notice the same patterns in the workplace. But I don&#x27;t want to turn this into work talk!</text></comment> |

Also, rolling out new versions of the application means either breaking the previous versions (with some instances still running) or doing the migration in several steps.<p>We believe there is a better way, they way pgroll works, you can start a migration, and keep the old &amp; new schemas working for as long as you need to rollout your app. If the new version of the app&#x2F;schema doesn&#x27;t behave as you were expecting, you only need to rollback the commit and undo the migration. pgroll guarantees that the previous version is still working during the whole process.<p>There is a graph in the readme depicting this concept:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;xataio&#x2F;pgroll&#x2F;blob&#x2F;main&#x2F;docs&#x2F;img&#x2F;migration-flow%402x.png">https:&#x2F;&#x2F;github.com&#x2F;xataio&#x2F;pgroll&#x2F;blob&#x2F;main&#x2F;docs&#x2F;img&#x2F;migratio...</a></text></comment> | <story><title>Pgroll: zero-downtime, reversible schema migrations for Postgres</title><url>https://xata.io/blog/pgroll-schema-migrations-postgres</url></story><parent_chain><item><author>candiddevmike</author><text>Help me understand the value of
undoable migrations. I&#x27;ve always operated under &quot;the only path is forward&quot; and you release a new version that fixes the issue or create a new migration that does some kind of partial rollback if necessary. Once a migration is live, naively rolling things back seems like you&#x27;re asking for problems.<p>I also only perform migrations as part of app init, not separately.</text></item></parent_chain><comment><author>contravariant</author><text>I don&#x27;t think &#x27;undoable&#x27; is the clearest description, the crux is this:<p>&gt; Keep two versions of the schema (previous and next) accessible at the same time during the whole migration process<p>This has some obvious advantages. Like you said you can&#x27;t easily roll back once a migration is fully live, but it helps <i>a lot</i> if you can cancel a migration once it turns out it doesn&#x27;t work.</text></comment> |

A town near me, Olds, just rolled out gigabit fiber to the curb for $57&#x2F;mo.<p>I do wonder if Olds is just covering their costs (likely) or are turning a profit (unlikely) (most municipal initiatives I&#x27;ve seen aimed to provide bandwidth at cost)?<p>The infrastructure is new and shiny now, and works well, but in 15 years what will it look like? Most state highways systems are in atrocious condition, let alone federal interstates. If the municipal is not turning a profit (even a slight one), there might not be incentive&#x2F;budget to continuously upgrade the infrastructure as new technology becomes available.<p>I think I would prefer a system in-which municipals lay and operate fiber throughout the city, but don&#x27;t connect to the end users -- instead leaving that up to small ISP&#x27;s to make the final termination and provide bandwidth (pay for the upstream, etc). This way the fiber can be available to a greater many small ISP&#x27;s and give them a good footing to compete with the BIG5 and more, while simultaneously providing an incentive to keep the infrastructure current (better than the small ISP&#x27;s could lay themselves and upgrades paid for by leasing fees from downstream).<p>Something along those lines would spur small business (small ISP) growth while forcing the BIG5 to play more fair since consumers would have a significantly larger selection of ISP&#x27;s in a relatively short time.</text></comment> |

Note that these considerations can occur prior to any code being written and also as part of an iterative process as the product and understanding of the product develops.<p>I believe this stems from three sources:<p>1. The criteria and process for getting promoted is very focused on shipping new and complex things which in practice is at the exclusion of all other considerations. This means that improving or maintaining existing systems or producing systems which are well architected at all is not as clearly valued. The promo committee is comprised of people who don&#x27;t know the specifics of the systems you&#x27;re working on so the easiest thing to convey is that feature X or product Y was shipped.<p>2. There is a hyper-rationalist, hyper-modernist, data-driven, anti-intuitionist view which pervades Google which completely discounts any sort of philosophical&#x2F;qualitative thinking. People get really uncomfortable when you try to start even the most anodyne discussion about the product or service as it relates to some broader goal since those involve qualitative judgements that can&#x27;t be reduced down a set of metrics. Some of this may be attributed to the CYA culture among management.<p>3. The interview process doesn&#x27;t select for software engineering or software architecture skills (aka people who have developed an intuitive understanding of the art of software engineering) so there are many people within Google who lack the ability to effectively evaluate the architecture choices that are being made around them or that they themselves are making.<p>With all that said I did meet and work with many brilliant engineers and others who were very talented and did think deeply about things but those were relatively rare. And yes it is a big company with many different teams and subcultures but what the author and I have described are the patterns that one sees broadly across Google.</text></comment> | <story><title>Pkg.go.dev is more concerned with Google's interests than good engineering</title><url>https://drewdevault.com/2020/08/01/pkg-go-dev-sucks.html</url></story><parent_chain><item><author>warent</author><text>These are fair criticisms.

Organophosphates are probably one of those things that we should continue studying in detail. They seem more trouble than they&#x27;re worth.

I always hear that level of chemical is so low it has no negative effect on a person. But you add up all the low levels of toxic chemicals and they add up to something significant! Pesticides, detergents, personal products such as perfumes, hair dye, make-up.. oh gosh. The list goes on. People are drenching themselves in chemicals then take pills to mask the effects.<p>And its expensive to avoid these things, my family of three spend about 2K per month on food alone trying to eat healthy. Nothing extravagant, fruits, vegetables, and organic when it matters. Sure we could live on $400 with highly processed or fast food... but you feel terrible afterword. The longer you stay away from them the more sensitive you are to toxic food.</text></comment> |

That&#x27;s how we learn and progress overall. Unfortunately for the people who do follow through with unconventional ideas, actually getting a thing to work doesn&#x27;t necessarily mean (financial) success.<p>In this case, there&#x27;s really one big benefit at the cost of a lot of negatives.<p>It can VTOL&#x2F;VSTOL. Most fixed wing airplanes cannot do that. So it can theoretically take off in a parking lot or a helipad or a small field. That&#x27;s really the only plus as I can tell.<p>The negatives are many compared to a traditional plane. In no particular order:<p>Less efficient cruising due to much more drag from all the ducts and engines.<p>Much less likely to fly with engine failures as they can dramatically affect control (since they are essential parts of the control system).<p>Less control surface stability with mechanical or hydraulic failures. Those engines mounted on the surfaces hanging off a hinge are very heavy, and in some failure cases they would hang low and create immense drag.<p>Yaw (rotational) control is highly dependent on working engines on both sides.<p>The glide ratio of the aircraft would be very poor with all the drag, even assuming the surfaces were still controllable (not hanging).<p>I didn&#x27;t see, but I assume a parachute is part of the plan for this.

For instance, if you are say, Goldman Sachs, would you want to use a private database at JPMorgan for you and your clients funds? Or would you prefer to use a semi-private blockchain, where although it&#x27;s not open to the public, each participant in the network has equal stature to one another? I think that is the true innovation here, and I do think that it is important. It solves some of the corporate cooperation issues that prevent certain types of value from being created, because nobody wants to let their competitor control the space.</text></item><item><author>simias</author><text>&gt;The coin will be issued on the Quorum blockchain which was developed by JP Morgan over the last year and is a private blockchain inspired by Ethereum.

This the the major reason why Electron is popular - the barrier to entry is very low.

The market size of people willing to pay taxi rates for transportation is <i>much</i> smaller that the market sizes currently implied by Uber and Lyft&#x27;s valuation. Before Uber and Lyft, most people I know would only take taxis very occasionally, for special occasions or emergencies. Once Uber and Lyft started offering such good rates they would use ride sharing much more often.</text></comment> |
