I never got in particularly much trouble, but many of my friends were screwed by minor miscommunication which incompetent adults escalated beyond any reason.<p>And yes, under the circumstances (assuming the goal is to avoid problems, instead of to aggravate the staff, perform ad-hoc psychology experiments, or the like), any high school student should avoid contradicting the staff in public, start by acquiescing to any request that doesn’t pose an immediate injury risk, disengage quickly and completely and then marshal their parents’ help if there has been any kind of mistake that will affect them academically.<p>Few teenagers have figured this out though. To any high school rule makers out there, please read <i>How to Talk So Kids Will Listen &amp; Listen So Kids Will Talk</i>, <a href="https:&#x2F;&#x2F;amzn.com&#x2F;1451663889&#x2F;" rel="nofollow">https:&#x2F;&#x2F;amzn.com&#x2F;1451663889&#x2F;</a> and in general, please try to treat the students with basic respect.</text></comment> |

It’s a bit like refusing to have gloves in your house, so that a burglar can’t borrow your gloves to avoid leaving fingerprints.<p>Adware, spyware, and malware has always had the ability to avoid system DNS. At its most basic, they could hardcode lists of IPs into their malicious code. At its most complex, the same building blocks that DoH&#x2F;DoT use were available to them: they could build similar tools that tunnel over HTTPS&#x2F;SSH&#x2F;etc, whichever protocol they felt was least conspicuous on their target system. Drop a list of hostnames into a pastebin post, tell your malware to check the list for updates, profit.<p>DoH in Firefox simply makes the above issue harder to ignore. Before this, an enterprise or individual sysadmin could implement DNS inspection at the border, see logs showing their users browsing naughty websites, and feel like they’d made progress. But they’d always be blind to attackers (or nefarious users) who just didn’t bother using the stock DNS offering to bootstrap their hijinks. Detecting that has always required device-level monitoring or further MITM of traffic; learning about DoH makes that more obvious to sysadmins, but it doesn’t materially change what adversaries were able to do already.</text></comment> | <story><title>Firefox 83 introduces HTTPS-Only Mode</title><url>https://blog.mozilla.org/security/2020/11/17/firefox-83-introduces-https-only-mode/</url></story><parent_chain><item><author>ignoramous</author><text>&gt; <i>I want my OS to do DNS - including DOH, not my browser.</i><p>The cat is out the bag, so to speak.

Ask any lucid dreamer and they will explain you than the key to lucid dreaming is to constantly question your current state(are your dreaming or not?).<p>And after some time it just doesn&#x27;t matter. Because every thing is just a electrical impulse to your brain. If your brain is sent a signal to treat hot as cold. You will hold a hot iron in your hands and be perfectly OK with it. The reality of things &#x27;hot being hot&#x27; doesn&#x27;t change, nothing changes but your perception of things.<p>If you ponder deep enough when you dream this is what happens in a dream too. You are perceiving things. Whether they are real are not, is as useless argument because your knowledge of it is the way your brain is telling you about it and not what it actually is.<p>I&#x27;ve had inception like dream within dream, losing lucidity while dreaming inside the dream and there after. In stages like that its difficult to say what is reality and what isn&#x27;t. The safest way is to not do any thing harmful or dangerous. In fact I didn&#x27;t know of it until I woke, it was then during a usual dream recall that I got a surreal feeling that I had woke up from three levels of &#x27;reality&#x27;.</text></comment> | <story><title>End of Inception decoded [video]</title><url>http://sourcefed.com/end-inception-de-coded/</url></story><parent_chain><item><author>AnonJ</author><text>That article seems far-stretched and circuitous, making things out of its own rather than really explaining what Nolan is trying to say(It&#x27;s actually not that complicated.

So the state could regulate homeschooling to ensure all children have access to an actual education.<p>&gt;If you feel these children are legitimately being abused in some way, I&#x27;m guessing there are plenty of state resources to address that challenge.<p>A lot of those resources rely on processes that come after reports from teachers and caregivers. If nobody outside the home ever sees or talks to the kids, there&#x27;s not much the state can do to even start an investigation. Children who go to daycare or public school are seen by professionals trained to spot abuse.<p>We allow anyone to have children, because otherwise we&#x27;re on a very slippery and short slope towards eugenics. But those children are entitled to the same rights and protections as their parents. It&#x27;s hard to strike a good balance between a family&#x27;s freedom and a child&#x27;s freedom.<p><i>Edited out some unnecessary detours in my ramblings</i></text></comment> |

I sometimes have to use the default shell of Linux distribution, especially on servers, and my main pain points with bash are:<p>- The history is editable by default. If I move to a previous history line and change it, the old line disappears. Hitting Ctrl-c will remove it from the history.<p>- If I use simultaneous shells (screen, tmux, or several ssh connections), the history saved will be the one of the last shell to quit. The bash config `histappend` should be the default, IMO.<p>- Most of the time, I search the history by the beginning of the command I just typed, which zsh maps to alt-p and which bash does not map by default. I rarely use the ctrl-r search.<p>- No way to pause a command and view the man. With zsh, `git clone&lt;alt-h&gt;` will display `man git-clone`, then return to the incomplete command line.<p>- No way to set a command aside.

That concentrated union power in the leadership which created an opportunity for more corruption, and also weakened certain powers that would make labor struggles more useful. Of course in Japan, they would likely use Japanese workers due to strong nationalist sentiment so this particular issue wouldn’t occur.<p>I’m only saying this because some will read your comment and take away “labor unions bad”. I suspect that the truth is we aren’t doing labor unions properly here, and also the desire to use Taiwanese workers suggests there is something lacking about the US education system. It is of course reasonable for US workers to want a chance, but we need to make sure they are worthy of that chance. You can leave it up to the market to let people find higher education, but that’s going to leave smaller numbers in the end due to how wealth is distributed in this country. If you want higher numbers of educated workers, more provisions for affordable education are required.</text></comment> | <story><title>TSMC is having more luck building in Japan than in America</title><url>https://www.economist.com/business/2024/02/22/tsmc-is-having-more-luck-building-in-japan-than-in-america</url></story><parent_chain><item><author>subtypefiddler</author><text>It boils down to<p>- Labor relations (unions in Arizona pushed back agains Taiwanese workers build the factory)<p>- Local partners (Denso&#x2F;Sony and Toyota investing in Japanese project, TSMC on its own in the US)<p>- Subsidies (Japan delivered on promises, US didn&#x27;t)<p>- Ambition (12nm-28nm in Japan, 4nm in US)<p>It seems the US gov is not very serious about it while Japanese gov surely is.

Furthermore it must understand some basic rules, such as, &quot;Any subject, set of subjects, or actions can be represented multiple ways.&quot;<p>So if you said, &quot;Mary&#x27;s brother is Sam,&quot; or &quot;Mary has a brother named Sam,&quot; or &quot;Mary&#x27;s brother is named Sam,&quot; the world model must collocate the meanings &quot;Sam&quot; and &quot;brother&quot; for Mary and be able to respond to queries about either.<p>Further, if you mention that John also has a brother named Sam, and then you mention Sam in an ambiguous context, the program should be smart enough to ask, &quot;Which Sam? Mary&#x27;s brother or John&#x27;s?&quot; Infocom games did this; you are building a more flexible world model builder, but the parser would operate similarly.<p>There is also the concept of recency. If I talk about &quot;John&#x27;s brother Sam&quot;, ignoring the fact that pronoun references to &quot;he&quot; should be contextually mapped correctly, and then mention Sam, the program should not need to ask which Sam I mean. It would be like talking to someone who wasn&#x27;t paying attention.<p>Finally, there is also the concept of confidence. In the face of ambiguity that can&#x27;t be resolved, a confidence rating should be assigned based on available information and future answers should be based on that confidence.<p>I suspect that if someone were to create a language parser that could create a mostly-accurate world model AND modify itself based on new rules it read (e.g., &quot;When some says &#x27;he&#x27; after referring to someone&#x27;s name, they are almost certainly talking about the man they previously referred to&quot;), you would be 90% of the way to creating a useful virtual intelligence. It would of course not be able to reason or have opinions of its own, but it would be extremely useful as a virtual assistant that could learn your preferences over time.</text></comment> |

But they can show <i>presence</i> of defects. So yes, a test suite that runs without errors tells you “nothing” in a way. But it&#x27;s a very good safeguard to ensure that code changes don&#x27;t inadvertently introduce unexpected changes.<p>For me it&#x27;s also the case that I think much more thorough about what inputs could be possible and potentially problematic, so there&#x27;s often an extra set of test cases around boundaries of input values that would have never been tried when just quickly throwing together a demo application to showcase and experiment with a new feature.<p>But the fundamental problem that lots of bugs don&#x27;t appear in testing since those code paths are never tested also means that testing alone isn&#x27;t sufficient. But I guess we all know that by now, and combining different kinds of tests with other approaches like code reviews (actual proofs are probably beyond the scope for the vast majority of software projects) is being done all the time to not bet everything on a misguided 100 % code coverage unit test approach that&#x27;s both expensive and fairly useless.</text></comment> | <story><title>I found a bug in SQLite</title><url>https://www.philipotoole.com/how-i-found-a-bug-in-sqlite/</url></story><parent_chain><item><author>adius</author><text>Just a few days ago I found a serious security issue in SQLite: <a href="https:&#x2F;&#x2F;sqlite.org&#x2F;forum&#x2F;forumpost&#x2F;07beac8056151b2f" rel="nofollow">https:&#x2F;&#x2F;sqlite.org&#x2F;forum&#x2F;forumpost&#x2F;07beac8056151b2f</a><p>It was also promptly fixed, but it makes me feel like the millions of tests sound better than they are in reality …</text></item></parent_chain><comment><author>komali2</author><text>I&#x27;m watching engineers re-implement error handling code I wrote line by line over the weeks after they &quot;optimized&quot; my error handling into a oneliner.

On top of this the Olympus engines generated a lot of thrust at idle, so much so that only two were used for taxing and it was still apparently tricky to control.<p>While cruising at supersonic speeds the engines were actually the most efficient machines of their time achieving 43% thermal efficiency [0]. Despite being very efficient they still had high fuel consumption rates as the total amount of energy required to sustain those speeds is a lot higher than subsonic.<p>Modern jet are in the 50%s thermally efficient [1] but despite airframe improvements there has been no way to improve fundamental aerodynamics so that supersonic energy costs aren&#x27;t high.<p>The Concorde did use reheat to take off and break the supersonic barrier which is very fuel inefficient.<p>Using a modern airframes and engines that also don&#x27;t need reheat will reduce fuel consumption but not to a level anywhere similar to a modern jetliner.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Rolls-Royce&#x2F;Snecma_Olympus_593" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Rolls-Royce&#x2F;Snecma_Olympus_593</a><p>[1] <a href="https:&#x2F;&#x2F;www.nap.edu&#x2F;read&#x2F;23490&#x2F;chapter&#x2F;6#38" rel="nofollow">https:&#x2F;&#x2F;www.nap.edu&#x2F;read&#x2F;23490&#x2F;chapter&#x2F;6#38</a></text></comment> | <story><title>Boom supersonic jet readies for rollout</title><url>https://www.airlineratings.com/news/boom-supersonic-jet-readies-rollout/</url></story><parent_chain><item><author>DomenicoMazza</author><text>If I recall correctly the Concorde used about 2 tonnes of fuel rolling on the ground alone..

Yes, I have seen poorly done source files. I made more than a few myself. However, many of the practices we have grown into as sound programming advice seem to be largely thrown out the window for these notebooks.<p>The irony, to me, is that I actually typically argue for the mixing of presentation and content. But to me, notebooks look like an attempt by people to make a WYSIWYG out of JUnit&#x2F;TestNG&#x2F;whatever style reports. Only, without the repeatability.<p>There is also the entire bend where these are taking off in a way that doesn&#x27;t make sense. Do they do the things you are saying? Well, yeah. But no better than plenty of tools before them. Mathematica and Matlab both had &quot;notebook&quot; like features for a long long time. Complete with optimized libraries. And this is ignoring the interactivity of the old LISP machines. (You can see from my history I have a soft spot for emacs org-mode.)<p>Jupyter is a lot of things.

C inherently has pointers. It has uninitialized variables. It has array overflows. It has all these problems that even if you have full control of your compiler and tool stack, you just can’t fix. To fix dangling pointers, you would have to fix lifetime issues, and C doesn’t have a framework to reason about that, and retrofitting that into a compatible way into the system just wouldn’t really work.<p>If you took away C from Objective-C, you couldn’t use C arrays on the stack, for example. And if you couldn’t do that, there’s entire classes of applications where the performance just wouldn’t be acceptable. We went around, around, around. We said the only way that this can make sense in terms of the cost of the disruption to the community is if we make it a safe programming language: not “safe” as in “you can have no bugs,” but “safe” in terms of memory safety while also providing high performance and moving the programming model forward.</text></comment> | <story><title>On Apple's Love Affair with Swift</title><url>https://stefan-lesser.com/2018/06/20/on-apples-love-affair-with-swift/</url></story><parent_chain><item><author>pavlov</author><text>Chris Lattner writes:<p><i>”One of the best and most annoying things about Objective-C is that it has C in it.

That’s really, really, really important for Objective-C being successful in both in the days of NeXT on 16 MHz processors and also today for the low-level code that people are writing.”</i><p>This is indeed a great thing about Objective-C: it’s an improved C with a tight set of runtime features that help build interactive applications.<p>There’s a need for such a language, and I’m sad that so much of the rhetoric from Apple and the Swift community is working on the assumption that Obj-C should be completely replaced by Swift.<p>Swift is not a compact language like Objective-C. It’s more like C++ in how it tries to incorporate every programming paradigm that can possibly fit. The heavy focus on complex upfront typing is not necessarily the best choice for iterative app development.<p>Swift is useful in many places, but personally I found Objective-C’s “Smalltalk-flavored C” to hit a sweet spot for my GUI needs where integrating with C and C++ libraries is usually required all over the place.</text></item></parent_chain><comment><author>coldcode</author><text>I have used Objective-C since 1997 when I worked with WebObjects back then and I don&#x27;t miss it for a second. When I have to touch our one codebase with Objective-C I have to groan. It was amazing for its day and I did enjoy it despite its shortcomings. But I can write way more highly functional code faster in Swift than I ever could in Objective-C due to real type safety and other modern features. I also spent years doing regular C and C++ and Java (not at the same time) and all 3 languages seem clunky to me now. Preferring Objective-C over Swift is wishing for the golden oldie days kind of thinking and I&#x27;m one with almost 4 decades of programming experience. Swift is still young and growing and sometimes thats a bit challenging to adapt, but its the one language I truly enjoy now.</text></comment> |

Sometimes I think that the many different interpretations of &quot;open source&quot; leads to clash and conflict. There is the side where open source is merely a way to share code, a side where it is primarily community oriented,a side where FOSS is a mechanism of freedom and liberation, and so on.<p>I think this incident makes me feel that in any commercially-focused open source project I create I should be clear or that intention. Otherwise my focus on releasing code, and building a business and the corresponding lack of focus on community niceties may come back to bite me.<p>Open source is not necessarily about the community and not necessarily about you. I think it would be good to fork the project to make a community focused variant. I don&#x27;t think the VCV rack guy, though, Is necessarily falling short of any duties, because from my external perception it was never a community focused project. For example, the core afaik (unless I&#x27;m thinking of something different) is not &quot;open contribution&quot; at all.</text></comment> | <story><title>Why I’ll never create modules for VCV Rack anymore–and what I’ll make instead</title><url>https://aria.dog/barks/why-i-will-never-create-modules-for-vcv-rack-anymore/</url></story><parent_chain></parent_chain><comment><author>deorder</author><text>That is horrible and I did not fully realize this was going on.

But they can vote and they can tell the CEO, you&#x27;re not getting another penny from us, we&#x27;d like to sell our shares. And that leaves the public markets as the investor of last resort.<p>So it does feel like a Unicorn reckoning is to be had.

Hence it will be much cheaper for companies to buy Google&#x2F;Microsoft Vision&#x2F;Audio REST APIs rather than paying the costs of: cloud + find data + deep learning experts. So, I don&#x27;t think we will see a massive growth of DL gigs.<p>e.g. Google Vision API: <a href="https:&#x2F;&#x2F;cloud.google.com&#x2F;vision&#x2F;" rel="nofollow">https:&#x2F;&#x2F;cloud.google.com&#x2F;vision&#x2F;</a><p>Except those areas where your own CNN implementation is needed (automotive, industrial automation), Deep Learning will be another &quot;library&quot; in the ever increasing Software Engineering mess of gluing many open source libraries and REST apis to get something useful done. You need 1 guy training a Neural Network for every 100 software monkeys maintaining the infrastructure complexity.
There are now many Software Engineering jobs because it&#x27;s hard to glue and maintain publicly-available code to solve some specific business problem.<p>I think the the same applies for many Data Scientist jobs, which are these days more about fetching&#x2F;cleaning&#x2F;visualizing data than making machine learning on it.</text></comment> | <story><title>How to Get a Job in Deep Learning</title><url>http://blog.deepgram.com/how-to-get-a-job-in-deep-learning/</url></story><parent_chain></parent_chain><comment><author>orthoganol</author><text>My question is, it feels like machine learning is reaching its &quot;Rails&quot; stage.

Even beyond the core setup it will do the peripherals - smart initializations, anti-overfitting, split up your data, etc.<p>Do people who implement (albeit real, useful) deep learning systems, but who have no formal machine learning background, who don&#x27;t really know much or care about implementing derivatives or softmax functions because the frameworks abstract all that away - are these people getting offered jobs?</text></comment> |

I remember doing J2EE in the early oughts everyone spoke about being able to swap out one RDBMS for another, and I eventually decided that kind of lowest-common-denominator approach was not worth the cost in preset-day productivity. Plus building on an open source project is less risky than something with outrageous licensing fees, so why not use it? So my own Rails projects have real foreign keys, CHECK constraints, some SQL functions (even some in C), views, and big queries. If I can express an invariant I trust Postgres more than myself to enforce it. I&#x27;ve also had some projects lately where building a JSON response for the front-end involved hundreds of ActiveRecord objects, and dodging that by using the JSON-construction functions in pg 9.4+ is a huge performance win. You can even still use the ActiveRecord DSL to build the query, using your scopes and associations and Ruby code, but then do a `to_sql` and wrap the whole thing in Postgres JSON fuctions. I feel like there could almost be a gem for that. Anyway, sorry for rambling. :-) I agree that Andl could make it much more appealing for people to &quot;put the logic in the database,&quot; and I feel like I have been moving in that direction for a long time. Maybe we will see an ActiveRecord Andl adapter?!</text></comment> |

The customer needs some problem solved. They assume the easiest way there is to get a different problem solved. They ask a customer support-type person about that. The CS person assumes a solution is best, and then go to a project manager. The PM assumes a particular implementation is best, and goes to a developer.<p>By the time the developer is trying to solve the customer problem, it has been transformed into a different problem at least four times, by mere assumptions that rarely have anything to do with reality.<p>Always, always ask &quot;Why am I doing this?

The software was written in C and there were no tools like Purify or Valgrind back then to deal with memory problem. It was a vexing problem that got punted until release time, when it became a show stopper.<p>I looked into the problem and found that the memory allocation used malloc and free. I then defined macros for malloc and free in a common header to call my_malloc and my_free functions with the standard __FILE__ and __LINE__ macros passed in as parameters. Re-compiled the whole program with the macros, which redirected every call of malloc and free to my functions. My functions logged all the calls with the allocated memory pointer, the filename, and the line number. Once I collected enough log data from test runs, I sorted the lines in the log file by the memory pointer address. Every pointer address should come in pair, one from the malloc() and one from the free(). The odd number pointer addresses are the ones with missing free().

After porting the code I benchmarked it - and, no surprises - it was waay slower than the original C code.<p>One reason C is faster than javascript is that C structs get &quot;inlined&quot; into the containing object. For example, in C struct Body { vec2 pos; vec2 velocity; } would just be 1 object. But the equivalent javascript code would allocate 3 objects instead.<p>I inlined vec2 (replacing it with pos_x, pos_y, etc) and performance got a lot better. But I was curious what other structs were thrashing the garbage collector. So I added a call into all my constructors which generated a stack trace (new Error().stack), and used the stack trace as the key in a javascript object - with the value being the number of times that stack trace was seen.<p>After sorting and printing the result, I had a hit list of the hottest stack traces which were thrashing V8&#x27;s garbage collector. I fixed all the worst call sites and by the time I was done performance improved by about 3x or so!</text></comment> | <story><title>Ask HN: What's your proudest hack?</title><text>I saw this question being asked on here years ago with few but interesting answers.

The software was written in C and there were no tools like Purify or Valgrind back then to deal with memory problem. It was a vexing problem that got punted until release time, when it became a show stopper.<p>I looked into the problem and found that the memory allocation used malloc and free. I then defined macros for malloc and free in a common header to call my_malloc and my_free functions with the standard __FILE__ and __LINE__ macros passed in as parameters. Re-compiled the whole program with the macros, which redirected every call of malloc and free to my functions. My functions logged all the calls with the allocated memory pointer, the filename, and the line number. Once I collected enough log data from test runs, I sorted the lines in the log file by the memory pointer address. Every pointer address should come in pair, one from the malloc() and one from the free(). The odd number pointer addresses are the ones with missing free(). And I got their filename and line number right there.</text></item></parent_chain><comment><author>bane</author><text>You know, that&#x27;s surprisingly an elegant hack.

Now I find it increasingly difficult to be enthused about anything AWS. It’s all so expensive, complex and locked in. I recently shut down everything I had on AWS except Route 53 and workmail, both of which I really like. The craziest AWS thing is that they moved all GPU instances to a quota system where you have to request access, specifying the number and type and location of instances that you want to run. It’s like Azure which has an equally terrible quota system. Anyhow I needed to run some performance tests in GPU instances. In the past I would have spun up a bunch of different instance types, run my tests and moved on. In this case I applied for a quota of one machine type and 24 hours later AWS got back to me to approve my request to run one instance. At that point I gave up on the idea of AWS being the heart of any GPU based infrastructure.</text></comment> |

But I think that instead of debunking this approach, it just limits its applicability.<p>(1) Keep the &quot;kvetching order&quot; for the (relatively) short time when the impact of the trauma is still very strong and hasn&#x27;t been processed by the person in the center.<p>(2) Do not allow two systems of kvetching rings clash. Yes, this includes both warfare, hopefully far from most people here, and, say, divorces.<p>This is not a universal solution. Taken too literally, or too long-term, it will harm the person(s) in the center it&#x27;s intended to protect. Yes, sometimes the only way out of pain is through, &quot;no pain, no gain&quot;. But this is a good rule-of-thumb kind of solution that helps limit the pain inflicted to the people <i>definitely more hurt than you</i>, without any significant gain. Maybe a traumatized person, for their long-term benefit. needs to have a difficult conversation that would be extra painful due to the trauma. But there&#x27;s no reason to inflict pain by small talk and trivial daily iissues.</text></comment> |

I was a classic nerd, including all the bad attributes that label comes with, but also one really good one: I was really into a number of things. But I learned from hard experience that being super into stuff was lame - being disinterested and too cool for stuff was hip. I internalized that attitude.<p>Even into adulthood, I occasionally find myself making fun of people for being into specific things. I eventually made myself a rule: if someone really enjoys something that&#x27;s not hurting anyone, that&#x27;s an admirable trait. It&#x27;s easy to obey this rule for things I like: science fiction, fancy beer, programming.

I was a classic nerd, including all the bad attributes that label comes with, but also one really good one: I was really into a number of things. But I learned from hard experience that being super into stuff was lame - being disinterested and too cool for stuff was hip. I internalized that attitude.<p>Even into adulthood, I occasionally find myself making fun of people for being into specific things. I eventually made myself a rule: if someone really enjoys something that&#x27;s not hurting anyone, that&#x27;s an admirable trait. It&#x27;s easy to obey this rule for things I like: science fiction, fancy beer, programming. It&#x27;s not too hard to obey this rule for things that I&#x27;m not personally into, but are culturally adjacent to me: classical music, literature, skiing, fancy coffee.

Unfortunately, it has been forgotten outside of database and query processing realm. A resurgence has happened in recent years, as PL researchers and also industry have discovered the virtues of datalog (e.g. Flix, DataFun). My own attempt at making this more widely known is here <a href="https:&#x2F;&#x2F;github.com&#x2F;google&#x2F;mangle">https:&#x2F;&#x2F;github.com&#x2F;google&#x2F;mangle</a>, a language from the datalog family and its implementation as a go library.<p>As the example shows: plain &quot;rules&quot; (or: plain datalog) is rarely enough to capture everything that one wants to express: the question then is, how to combine a pure declarative &quot;kernel&quot; with more general purpose programming (e.g. mapping a list).<p>PROLOG offered one answer, already in the 1980s, but I fully reject it: the fact that the writing a program in the wrong order with negation and recursion makes it non-terminating is not something we&#x27;d want everyone to deal with. Datalog with stratified recursion is somewhat better, as &quot;layers of rules&quot; is a concept that is easy to understand.<p>In mainstream programming languages, the possibility of writing non-terminating programs also exists, but is rarely an issue. That is why I believe a good combination of declarative and general-purpose has to make it really easy to recognize which parts of a program are in the declarative, terminating, safe kernel and which parts require more attention from the programmer.</text></comment> | <story><title>Prolog for data science</title><url>https://emiruz.com/post/2023-04-30-prolog-for-data-science/</url></story><parent_chain></parent_chain><comment><author>henrydark</author><text>A different, also very explicit way to go about this type of problem, that also generalizes fully, is to use a Bayesian hierarchical model of a dirichlet process and sub-isotonic regressions.<p>Gelman et al have written a lot about this, and they have a proposed general workflow [1]<p>[1] Bayesian Workflow <a href="https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2011.01808" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2011.01808</a></text></comment> |

Instead, the post is identifying the Android SDK as non-free because you have to agree to Google's Terms and Conditions in order to use it at all. That's absolutely correct, however...<p>As someone who downloaded the original SDK in 2007, I can tell you that this was true from the beginning. Sadly the Wayback Machine is having trouble retrieving their first crawl of the terms (February 2009), but here's a crawl from January 2010 that shows that the offending clause has been there for at least 3 years: <a href="http://web.archive.org/web/20100111025451/http://developer.android.com/intl/ja/sdk/terms.html" rel="nofollow">http://web.archive.org/web/20100111025451/http://developer.a...</a><p>A more accurate title would be: Google's Android SDK has always been proprietary, but I only just noticed.<p>Edit: Based on the date at the bottom of the wayback page, the linked version of the agreement dates back to April 2009.</text></comment> | <story><title>Android SDK is now proprietary</title><url>http://blogs.fsfe.org/torsten.grote/2013/01/03/android-sdk-is-now-proprietary-replicant-to-the-rescue/</url></story><parent_chain></parent_chain><comment><author>codeflo</author><text>At first I thought this is hyperbole, but there's an anti-forking clause in the license agreement:<p>&#62; "3.4 You agree that you will not take any actions that may cause or result in the fragmentation of Android, including but not limited to distributing, participating in the creation of, or promoting in any way a software development kit derived from the SDK."<p>IANAL, but this seems to be designed to prevent projects like the Kindle Fire from building their own ecosystem on Google's code.

Most of the above arguments don&#x27;t hold good at all.
* c++ std lib is total crap. Anyone arguing for it has no idea what a good API is. Have you used Qt container? It&#x27;s as intuitive as it gets. The C++ std lib is performance optimized and most desktop apps don&#x27;t need it. It comes at a cost of developers having to learn complex APIs.<p>* Complex object hierarchies - huh? Qt&#x27;s value based types need no memory management. The pointer types has a simple parent-child relationship. Delete the parent and all children are deleted as well. How hard is this?<p>* Raw pointers - Commented truly like someone who hasn&#x27;t understood Qt.<p>* Why do you care about UTF16? It&#x27;s an internal representation. BTW, Do you write any web apps? Do you know or care what internal representation is used by strings? If you some ultra-special case of a performance critical app, no string library out there will be good for you. You will have to roll out your own.<p>Let me guess. It really looks like you are one on the few guys who likes writing libraries (as opposed to apps). People who write apps love Qt. People who like writing libraries don&#x27;t like any other library other than their own because their way is the true way.<p>There are many valid criticism of Qt but these are none of them.</text></comment> |

After the initial C to Rust pass you end up with the same program, with a C-like architecture, and all you&#x27;ve done is replaced gcc with a slower rustc.<p>But wrapping a C implementation in a Rust API works <i>great</i>. You can translate C&#x27;s implied ownership semantics into explicit Rust types. You can wrap all these C structs&#x2F;handles with their init and free functions into RAII that never leaks.<p>It&#x27;s something you can do in days, not months to years.

It&#x27;s a big reason I&#x27;m a fan of liberalism (in the British rather than American sense) and subsidiarity, central planning in my opinion usually leads to poorer results because the people on the ground in a given situation tend to make better and more informed decisions than someone sitting at a desk in London with many degrees of seperation from the situation at hand. The solution I think is to make government as local as possible so that different places can have different priorities without breaking things for other people.<p>I believe that politics ought to be as decentralised as practically possible and political abstractions are employed only when absolutely necessary (ie it&#x27;d be a bit silly to ask Ceredigion County Council to run its own nuclear energy programme). Not only does this reduce tensions between ideologically diverse areas, it also frees up what remains of the central government&#x27;s power to focus on long-term globally important issues rather than flitting about with the issues of the day. We need to dispense with this &quot;winner takes all&quot; approach to politics where the most powerful ideological minority can lord it over everyone else for five years at a time and instead adopt a much more &quot;each to their own&quot; approach in my opinion.<p>The two big barriers to this approach are a) politicians that currently rule the roost of a highly centralised system would be loathe to give up their power - it&#x27;s very rare that powerful people have the moral fibre to selflessly abandon power and influence for the greater good of humanity and b) current local government infrastructure is pretty atrocious, it&#x27;s often made up of ridiculous retirees with nothing better to do than exercise their instincts for petty tyranny.</text></comment> |

They’re both declarative languages, but GraphQL is declaring a desired data format, whereas SQL is declaring (roughly) a set of relational algebra operations to apply to a relational database. GraphQL is really nothing like an ORM beyond the fact that they are both software tools used to get data from a database. You might use an ORM to implement the GraphQL resolvers, but that’s certainly not required.<p>I wouldn’t expect the performance issues to be much more problematic than they would be for REST endpoints that offer similar functionality. If you’re offering a public API, then either way you’re going to need to solve for clients who are requesting too many expensive resources. If you control the client and the server, then you probably don’t need to worry about it beyond the testing of your client code you would need to do anyway.<p>As far as query optimization goes, that’s largely out of scope of GraphQL itself, although many server implementations offer interesting ways to fulfill GraphQL queries. Dataloader is neat, and beyond that, I believe you can do any inspection of the query request you want, so you could for example see the nested path “Publisher -&gt; Book -&gt; Author -&gt; name” and decide to join all three of those tables together. I’m not aware of any tools that provide this optimization automatically, but it’s not difficult to imagine it existing for some ORMs like those in Django or Rails.</text></comment> | <story><title>How and why GraphQL will influence the Sourcehut alpha</title><url>https://sourcehut.org/blog/2020-06-10-how-graphql-will-shape-the-alpha/</url></story><parent_chain><item><author>WhatIsDukkha</author><text>I don&#x27;t understand the attraction to Graphql.

But even then there&#x27;s still some value in letting the client specify the shape of the the data it needs and having client SDKs (there&#x27;s definitely non-GraphQL ways to achieve these too).<p>My impression is GraphQL starts to shine when you have multiple backend systems, probably separated based on your org chart, and the frontend team needs to stitch them together for cohesive UX. The benchmark isn&#x27;t absolute performance here, it&#x27;s whether it performs better than the poor mobile app making a dozen separate API calls to different backends to stitch together a view.</text></comment> |

First of all, the excesses presented in December are more noteworthy because they demonstrated how much information flows between the supposedly &quot;independent&quot; general experiments. In December the global CMS excess (the one that matters) was 1.2 sigma, but heyoo a little bird told us ATLAS sees a 2 sigma global excess at the same place so into the slides it goes! So much for independence...<p>Since then there was an update in march where ATLAS still sees a global significance of 2 sigma and CMS is down below 1. Local significances are up though CMS has pushed their 2.6 to 2.8, and ATLAS has gotten their 3.6 sigma into 3.9 (Both have also added a new model for interpreting this, I&#x27;m just giving the largest sigma values reported). The reason improvement is so modest is because there hasn&#x27;t been any new data on account of the LHC being set in the &quot;off&quot; position.<p>Anyway, the reason the OP article is such crap is that it doesn&#x27;t mention any details about the rumour it is so clearly based on. Perusing more technical rumourmongers I find a mention of a 4.7 sigma excess in an ATLAS analysis that wasn&#x27;t approved in time for the big conference in March. So if the article is based on that rumour, it is about three months old by now. But we can&#x27;t tell, since the author wusses out on even saying what detector will &quot;CRACK PARTICLE PHYSICS WIDE OPEN&quot;... -_-</text></comment> | <story><title>Hints of an unexpected new particle could be confirmed within days</title><url>http://blogs.scientificamerican.com/guest-blog/is-particle-physics-about-to-crack-wide-open</url></story><parent_chain></parent_chain><comment><author>pdonis</author><text>Unfortunately, this sort of linkbait headline has become typical for Scientific American (which is one of the reasons I haven&#x27;t subscribed for years). As has already been pointed out in these comments, the Standard Model is already believed to be incomplete by particle physicists, and discovering a new particle in this general energy regime is exactly what everyone has been hoping for for a couple of decades now. Yes, such a new particle is not included in the Standard Model--because there hasn&#x27;t been any experimental evidence for one. If this discovery pans out, particle physicists will finally be able to start model building again the way it was done when the SM itself was built: based on good experimental data.</text></comment> |

There&#x27;s a lot of surplus tooling on Ebay, and they&#x27;re by far the best connectors I&#x27;ve ever used. Rugged, really high pin density, and impossible to insert wrong. The prices are high for new tools, but there&#x27;s tons of surplus floating around thanks to government standards. There&#x27;s also solder-cup versions of a lot of the connectors so that no crimp tools are required. If you want to use the crimped versions, you&#x27;ll want the M22520&#x2F;1 basic tool or M22520&#x2F;2 miniature tool for smaller wire gauges. You&#x27;ll also need a positioner to hold the crimp in the right position within the tool (these are interchangeable for a ton of different models). You&#x27;ll probably want the M22520&#x2F;1-04 turret head. A Chinese company called JReady sells new crimp tools with the positioners for $300. It sounds like a lot, but it&#x27;s much less than the $800 American made tool and even less than the single purpose crimp hand tools for cheaper Molex and JST connectors. One tool standard, lots of different high quality connectors!</text></comment> | <story><title>Digikey's Physical Connectors Tutorial</title><url>https://www.digikey.com/en/articles/connector-tutorial</url></story><parent_chain></parent_chain><comment><author>mitthrowaway2</author><text>This is a good tutorial. Connectors are very tricky purchases; even if you do know exactly what you want, it&#x27;s easy to buy the wrong version of a part, or forget to buy a necessary part of an assembly, or struggle to find the correctly-mating part that you know you need, or lack the crimping tool that goes with it, and so on. And they are expensive, so errors are costly. The difficulty, and cost, is why a lot of hobbyists (and even professionals) often stick to the same few connectors that they are familiar with. But sometimes you need to branch out; maybe you need something waterproof, or something which handles higher current, etc, and then you can spend hours looking through catalogs.</text></comment> |

As an anecdotal example, when visiting Beijing, I had some trouble breathing, so I went to a pharmacy to buy an inhaler. I didn't have insurance that worked in China, so I had to pay out of pocket.

I remember you had a choice between two programming language and on one side they taught Fortran and Fortran is the language of science, or it was the language of scientists.<p>[00:07:40] And then there was this new class that was started by this Professor Niklaus Wirth about Pascal. And it was, I think the first or second year it was taught. There were a lot of people in the Fortran class and not that many people in the Pascal class. So I said, oh, I&#x27;ll go to the Pascal class.<p>[00:07:59] And that&#x27;s how I met Professor Wirth. And that was great. That was my favorite class from that moment because he&#x27;s such a, such an enlightened person and a clear thinker that it was a great, great experience for me.</i><p>[1] <a href="https:&#x2F;&#x2F;ethz.ch&#x2F;en&#x2F;news-and-events&#x2F;eth-news&#x2F;news&#x2F;2022&#x2F;05&#x2F;we-are-eth-podcast-philippe-kahn.html" rel="nofollow">https:&#x2F;&#x2F;ethz.ch&#x2F;en&#x2F;news-and-events&#x2F;eth-news&#x2F;news&#x2F;2022&#x2F;05&#x2F;we-...</a></text></comment> | <story><title>Niklaus Wirth, or the Importance of Being Simple</title><url>https://cacm.acm.org/blogs/blog-cacm/279178-niklaus-wirth-or-the-importance-of-being-simple/fulltext</url></story><parent_chain></parent_chain><comment><author>dang</author><text>Recent and related:<p><i>Closing word at Zürich Colloquium (1968)</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38883652">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38883652</a> - Jan 2024 (28 comments)<p><i>Niklaus Wirth, 1934-2024: Geek For Life</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38871086">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38871086</a> - Jan 2024 (61 comments)<p><i>Niklaus Wirth has died</i> - <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38858012">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38858012</a> - Jan 2024 (403 comments)</text></comment> |
