&gt; Each of these tasks I am setting for myself needs to be answered by consulting tutorials and references, but if I just follow a tutorial I will not build true knowledge, I will just know how to do things when someone is holding my hand.<p>That makes so much sense, thanks for the advice. I struggle with this too much nowadays, I just try too much to reach perfection too soon when learning new technologies. Thinking about this made me realize how this wasn&#x27;t how I started when I was younger. I wasn&#x27;t going for perfection, I was going for something that worked. Slowly afterward I learned the more technical parts, mostly by need, and the best practice, first by need, but then by desire. Nowadays I think that because I can handle some pretty technical knowledge, I can start by learning that, but seems like I waste quite a bit of time doing this and it just doesn&#x27;t stick in my head.<p>Next time I&#x27;ll learn something, I&#x27;ll start that way, a crude experimentation, and then see from there the next steps. Screw the best practice, that&#x27;ll just be another experimentation down the line, could even be some rewrite of previous experimentation.</text></comment> | <story><title>Ask HN: How do you learn complex, dense technical information?</title><text>When in the past I&#x27;ve picked up a reference manual or something of the sort I&#x27;d go slowly, lookup every word I didn&#x27;t understand and started experimenting as soon as possible.<p>But that is quite time consuming and intense.

Its like buying McDonalds at an isolated highway rest stop - I don&#x27;t particularly love McDonalds, but if my choices are a hot meal or whatever I can get from a vending machine or pack with me, I&#x27;ll take the hot meal every time.

Actually I blame Google for killing Usenet. They used Microsoft&#x27;s EEE (Embrace, Extend, Extinguish). They acquired DejaNews, renamed it to Google Groups, provided a gateway that allowed everyone to use Usenet. This introduced a lot of spam to the network, but whenever someone reported it, they did nothing. Eventually they introduced their internal groups, and shifted search in a way that it got hard to use Google Groups for searching Usenet posts.<p>They did similar thing with XMPP (Jabber). When they introduced Google Talk, their service was interconnected with the other XMPP servers. Once it got popular they discontinued it and introduced Hangouts (then later iterations) Hangouts was still connected people could see each other being present people on Hangouts could message anyone, but people on other XMPP couldn&#x27;t message people on Hangouts. It didn&#x27;t even show an error. This made many users switch to Hangouts to continue taking with their friends.<p>They attempted to do the same thing with email, but were less successful (since many big companies are also providing the service), this was done through introducing various anti spam measures. You now have to jump through various hoops (SPF, DKIM, RBAC) to have your service still reach Google uses. It didn&#x27;t matter that I used the same IP and domain for 15 years never had spam sent from it, but suddenly my emails started being silently classified as spam without any warning.</text></comment> | <story><title>The old internet died and we watched and did nothing</title><url>https://www.buzzfeednews.com/article/katienotopoulos/how-we-killed-the-old-internet</url></story><parent_chain><item><author>api</author><text>You&#x27;re forgetting spam.

My dad would relentlessly quiz me on the concepts, and he was ruthless in making sure that I understood <i>why</i> the formula was used just as much as <i>how</i> it was used.

When we create environments that embed even richer concepts, children learn those concepts just as easily.

It&#x27;s not an ID per bot and there&#x27;s no way to change the ID without deleting your Telegram account and creating it again later (I&#x27;m not sure if it changes then either). Bots can also see and save your name (as entered on the profile) on Telegram. This makes it easier for bots (or bot swarms) to track users on Telegram.

It has many features other platforms lack, is reasonably privacy-friendly, more so than fb&#x2F;whatsapp&#x2F;etc, but not enough to sacrifice features or UX. The have an API ind both official and unofficial clients for almost all platforms, including command line and native, non-electron Windows (UWP). The client API is not easy to use, as crypto and similar features are involved, but C libraries exist. On the other hand, the bot API is one of the most pleasant APIs I&#x27;ve ever seen. It just works, can be tested in the browser, there&#x27;s no oAuth crap one needs to set up. It&#x27;s beautifully simple. I use Telegram whenever I can, and it has become my goto Messenger these days.</text></comment> |

The problem is that people build up proofs like they&#x27;re something to freak out about, or that the proofs that are presented are inherently mechanical because that&#x27;s what students are taught. You can&#x27;t expect someone learning to write proofs to be perfect any more than you can expect a first-time drawer to color within the lines. It&#x27;s okay and should be embraced as an opportunity to reflect and improve. A proof is not complete just because you &quot;got to the answer.&quot; It&#x27;s complete when it&#x27;s simple, elegant, and easy to explain to others.<p>I can and have explained beautiful proofs without the need for mechanical proficiency to ten year olds and mathphobes alike.

3. Yes, it still rattles my brain that Algebra teachers force students to memorize the quadratic formula. It&#x27;s ridiculous. The method of completing the square is straight forward, more applicable in other situations, and can even derive that verbose formula.

If you start shifting from &quot;living as long as possible&quot; to &quot;living with the most dignity up until the end&quot;, you end up questioning euthanasia, but also how people live post work-life: typically, how people are going to live decently through their last stage post 60s, can they enter a stage where they are relieved from the stress, pain, etc. You can&#x27;t just say &quot;well let them die earlier&quot; if you don&#x27;t provide some form of hope of relief for their last years.<p>Today I&#x27;d argue that the growing lifespan is used as an argument to make people work longer, which means in worse physical conditions. The &quot;Work until your death&quot; motto (the curse of people living in poverty) is not great for a healthy and attractive society. Questioning it ends up in a heated political&#x2F;societal&#x2F;philosophical discussion pretty quickly. And we&#x27;re definitely not heading in the healthy direction: not because we don&#x27;t want to shift the medical institution, but because we need a more profound society change. From a purely economical PoV, it&#x27;s great that people die before around the beginning retirement, from a societal PoV it&#x27;s a disaster.</text></comment> | <story><title>Alzheimer's: 'Promising' blood test for early stage of disease</title><url>https://www.bbc.co.uk/news/health-53567486</url></story><parent_chain><item><author>coldpie</author><text>I have an idea that&#x27;s been floating around in my head for a while, and I don&#x27;t know how I feel about it.

Add a lot of zeros to a number series and it gets pretty low.<p>Ancient comedy even had a stock character, sexex iratus: angry old man. Certainly there are many more very old people now, but it wasn’t something totally unknown.<p>The aging of people has also coincided with a decline in our physical health and diets. Strength is declining year on year: we have grip strength measures for college age students since the 1980s and it is a steady decline. Diets are worse, people are much fatter and with more health problems such as type 2 diabetes.<p>One of the theories of alzheimers is that it is a form of diabetes. <a href="https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pmc&#x2F;articles&#x2F;PMC2769828&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pmc&#x2F;articles&#x2F;PMC2769828&#x2F;</a><p>Certainly it is correlated with type 2 diabetes, and with obesity in mid life.

(The last chapter of HPMoR went up on Ultimate Pi Day - 3&#x2F;14&#x2F;15 - last week.) I picked it up on the advice of some friends, and while the editing is less than perfect, it is overall an impressively well-organized and cross-linked treatise on how to reason.<p>At the heart of the book is the assertion that rationality is not about justifying why we are <i>right</i>, but thinking how we might be <i>wrong</i>, and paying careful attention to any evidence that puzzles us or could convince us to change our minds. The resulting philosophy is a combination of the falsification principle and the scientific method, applied to your own character.

For instance crossbar.io uses it [0]. Some shops use it as a second step until they refactor code into a compiled language, but often that second step never materializes.<p>But the value of a second implementation of a language goes beyond the immediate &quot;who uses this in practice&quot;. It can be a fertile bed for innovation and for new ideas, and provides a contrast to the nay sayers. For instance, the recent pitch to vastly improve CPython&#x27;s speed has some roots in ideas that were tested out in PyPy. CFFI [1], revdb [2] and vmprof [3] all started as PyPy projects. Some of these turned out to be very popular, some less so. The next project in this line is HPy [4] (still alpha-quality), which is trying to re-think the C-API for Python to make it even easier to interface with.<p>RPython [5], the language behind PyPy, is also an accessible playground for dynamic language research.<p>[0] <a href="https:&#x2F;&#x2F;crossbar.io&#x2F;about&#x2F;FAQ&#x2F;#python-runtime" rel="nofollow">https:&#x2F;&#x2F;crossbar.io&#x2F;about&#x2F;FAQ&#x2F;#python-runtime</a><p>[1] <a href="https:&#x2F;&#x2F;cffi.readthedocs.io&#x2F;en&#x2F;latest&#x2F;" rel="nofollow">https:&#x2F;&#x2F;cffi.readthedocs.io&#x2F;en&#x2F;latest&#x2F;</a><p>[2] <a href="https:&#x2F;&#x2F;morepypy.blogspot.com&#x2F;2016&#x2F;07&#x2F;reverse-debugging-for-python.html" rel="nofollow">https:&#x2F;&#x2F;morepypy.blogspot.com&#x2F;2016&#x2F;07&#x2F;reverse-debugging-for-...</a><p>[3] <a href="https:&#x2F;&#x2F;vmprof.readthedocs.io&#x2F;en&#x2F;latest&#x2F;" rel="nofollow">https:&#x2F;&#x2F;vmprof.readthedocs.io&#x2F;en&#x2F;latest&#x2F;</a><p>[4] <a href="https:&#x2F;&#x2F;hpy.readthedocs.io&#x2F;en&#x2F;latest&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hpy.readthedocs.io&#x2F;en&#x2F;latest&#x2F;</a><p>[5] <a href="https:&#x2F;&#x2F;rpython.readthedocs.io&#x2F;en&#x2F;latest&#x2F;examples.html" rel="nofollow">https:&#x2F;&#x2F;rpython.readthedocs.io&#x2F;en&#x2F;latest&#x2F;examples.html</a></text></comment> | <story><title>PyPy Project looking for sponsorship to add support for Apple Silicon</title><url>https://morepypy.blogspot.com/2020/12/mac-meets-arm64.html</url></story><parent_chain></parent_chain><comment><author>smspf</author><text>A couple of years ago we reached out to the python community about wheels and arm64 - how it should be handled and whether they plan on embedding non-x86 blobs.
We received the standard &quot;we&#x27;ll think about it and let you know&quot;.
Now that Apple switched to arm64, all communities are suddenly interested in porting things to arm64.<p>And of course, Apple is not investing in these ports, at least as far as I know. They just rely on what other arm64 players did in the ecosystem before Apples rolled out M1; respectively lets developers figure out the remaining porting.<p>As much as I hate to say this, IBM does handle porting things to ppc64 right - you can find IBM contributed code and optimizations anywhere you look. For many packages, porting to arm64 was a matter of &quot;does it have ppc64 support? if so, it can be reused for arm64&quot; ...<p>Disclaimer - used to be a contractor porting stuff to arm64 for a couple of years.</text></comment> |

Even if much of the work is offloaded to the corporations backing modern free&#x2F;libre browsers (e.g. keeping up with new web standards and technologies), it certainly goes without saying that rebasing with upstream or even just applying the latest security fixes is no trivial task I would entrust any browser fork with minimal developer backing with.<p>This problem is especially worsened with the kind of user base that firefox forks tend to attract, from what I have seen. These users tend to ask very high-level questions e.g. &quot;is waterfox more secure than pale moon&quot; and will usually blindly switch from one fork to the next based on poorly-backed, unsubstantial crowd opinion. No userbase means waning support + maintenance. If you ask me, I think in the very special case of browser technologies, it would be more beneficial if the developers and users of firefox forks directed their energies towards making generally desirable changes in upstream.</text></comment> | <story><title>Librefox: Firefox with privacy enhancements</title><url>https://github.com/intika/Librefox</url></story><parent_chain><item><author>elagost</author><text>This seems like an a slightly more complete version of Firefox Profilemaker (<a href="https:&#x2F;&#x2F;ffprofile.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;ffprofile.com&#x2F;</a>).<p>I personally use a fairly vanilla Firefox with a few addons and try to keep customization as default as possible.

While it was much easier to understand how to implement Raft, I think my students gained deeper insight when focusing on single-decision Paxos. There is a lightbulb moment when they first understand that consensus is a property of the system that happens first (and they can point at the moment it happens) and then the nodes discover that it has been achieved later. Exploring various failure modes and coming to understand how Paxos is robust against them seems to work better in this setting as well.<p>I think this paper by Heidi Howard and Richard Mortier is a great way to move on to Multipaxos:<p><a href="https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2004.05074" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2004.05074</a><p>They present Multipaxos in a similar style to how Raft is laid out and show that Multipaxos as it is commonly implemented and Raft are almost the same protocol.<p>Raft was a great contribution to the engineering community to make implementing consensus more approachable, but in the end I don&#x27;t think the protocol itself is actually more understandable. It was presented better for implementers, but the implementation focus obscures some of the deep insights that plain Paxos exposes.</text></comment> | <story><title>Raft: Understandable Distributed Consensus (2014)</title><url>https://thesecretlivesofdata.com/raft/</url></story><parent_chain></parent_chain><comment><author>benbjohnson</author><text>Author here. I&#x27;m happy to answer any questions although this project was from 10+ years ago so I could be a little rusty.<p>Over the years I&#x27;ve been trying to find better ways to do this kind of visualization but for other CS topics. Moving to video is the most realistic option but using something like After Effects takes A LOT of time and energy for long-form visualizations. It also doesn&#x27;t produce a readable output file format that could be shared, diff&#x27;d, &amp; tweaked.<p>I spent some time on a project recently to build out an SVG-based video generation tool that can use a sidecar file for defining animations.

If you read stories in the New Yorker, or the Atlantic, or similar publications, then you'd find equally "naval-gazing" writing from "real" reporters.<p>When I write a post, or when a journalist writes a story, or when you write a comment, you want to have an angle: something that sets your writing apart from the other thirty people who are writing about the same thing. Many publications today will cover detailed information about Mountain Lion. Gruber knows that. Further, there's not actually much new in Mountain Lion: Gruber successfully summarizes the new release in a handful of words in a middle paragraph. While I suppose he could go into more detail on interface minutia between Contacts and Address Book, or pontificate on why Notification Center on OS X looks more like Growl and less like the iOS pull-down, even doing that would provide him relatively little material.<p>Instead, Gruber focused on the culture of the event. From a company so well known for massive product releases and on-stage demos, the idea of doing not just one, but a large number of in-person demos across the country represents a substantial shift. It could symbolize any number of things, from a lack of confidence to a desire to repair image damage from Foxconn, which is why Gruber finds a need to emphasize how polished the presentation was and how the event was set-up in detail.<p>I can understand why this might feel like naval gazing, but to me, it's anything but. Gruber is in a unique position to comment on the cultural shifts of Apple, precisely because he's so involved with that selfsame culture. If he's going to comment on Mountain Lion's release this morning, that's going to be his angle. It's completely fine if you don't find it interesting, but questioning his competency, or calling this approach conceited, is wrong.</text></comment> | <story><title>Mountain Lion: John Gruber's personal briefing</title><url>http://daringfireball.net/2012/02/mountain_lion</url></story><parent_chain><item><author>beatpanda</author><text>When journalists say they're different from bloggers, what they're talking about is the kind of navel-gazing bullshit that Gruber spends half his time on here — describing the event itself, and his presence and experience there, making sure the reader knows that he was among only a few dozen people invited to this exclusive one-on-one press briefing.<p>A more competent writer would have spent maybe a sentence or two explaining the novelty of the briefing and then moved on.

Gruber was trying to convey a sense of how <i>different</i> this is from the Apple of days gone by.

The sole reason for the difference is the strain of yeast used.<p>And it&#x27;s not just a wheat beer thing: in general, American yeast strains are bred to produce cleaner fermentations than European strains.

With your &#x27;throw it all in a box&#x27; system, you have a high barrier to finding documents in the future and this discourages you from doing so. However, with a more organised approach you are more likely to retrieve specific documents.<p>One example: Some mid-priced electronic device breaks a few months after you buy it. You might weigh digging through all the paperwork versus shrugging your shoulders and throwing it away. I would go straight to the warranty document and also look at my credit card issuer&#x27;s warranty&#x2F;returns policies(if any), and I would return the item for a replacement or refund. No biggie, only a few minutes work and I as a consumer prevail in exercising my rights.<p>Sounds boring but I believe it is definitely worth making the effort.</text></comment> | <story><title>Show HN: Open Paperless – Scan, index, and archive paper documents</title><url>https://github.com/zhoubear/open-paperless</url></story><parent_chain><item><author>jopsen</author><text>Question: why bother organizing papers?<p>I just throw everything in a box, if I ever need it again later it&#x27;ll take a long time to find.. but I rarely need to find a document again.<p>Complexity of archiving a document is O(1) with a very small constant.

The active process of reading - each and every effort - builds the associative networks. To me that's what is so pernicious about the most popular platforms of the internet today. Because information is a click away, the immediacy masquerades as depth. Blogs, tweets, comments, and updates just feed the perception of being educated. By contrast, essays and books require a significant effort to digest. The effort is meaningful in building the pathways. That's why education is stressful. We're working to re-orient our heads. Walking up a mountain may just start out as one foot in front of another. 3,000 feet later we <i>really</i> appreciate and understand the height we've climbed.</text></comment> | <story><title>Why read books if we can’t remember what’s in them?</title><url>http://www.nytimes.com/2010/09/19/books/review/Collins-t.html</url></story><parent_chain><item><author>Arun2009</author><text>My key take-away from the article was this quote:<p>“There is a difference,” she said, “between immediate recall of facts and an ability to recall a gestalt of knowledge.

You could simply tell a child that "the Boy Who Cried Wolf is about a boy who kept lying then got eaten by a wolf because no one believed him when he was telling the truth." But largely, the message would be lost.<p>Without the context of the rest of the story, getting the child emotionally involved, getting the child to see the short term benefits, the impact of reading about how the kid gets eaten when he finally does see a wolf, tells the truth, and no one believes him is greatly diminished.<p>Studies have shown that people remember how facts/events/information makes them feel more accurately than the specific facts/events/information, and I think the idea of context is similar. You remember the emotions you felt when you read a story about X action, you remember the context of your emotions, even if you don't remember the specific cause.</text></comment> |

But thinking about it for a bit, it is wrong too. First, naming is hard. Finding good recognizable name for a package is hard enough, if each BC break would require a new one, we&#x27;d drown in names. Second, behavior breaks are not total. If RoR or ElasticSearch releases a new version with BC break, they do not stop being essentially the same package just with somewhat different behavior. Most of the knowledge you had about it is still relevant. Some pieces are broken, but not the whole concept. New name requires throwing out the whole concept and building a new one, essentially.

&gt; Predicating the availability of any of Google’s apps, including the Google Play Store, on OEMs not taking advantage of the open source nature of Android on devices that will not include Google apps seems much more problematic than Google insisting its apps be distributed in a bundle. The latter is Google’s prerogative; the former is dictating OEM actions just because Google can.

This is important, as the whole object of the lab accreditation process is to provide traceability to the primary standard.<p>There&#x27;s not much option here apart from repeating the measurements in a traceable way, as one can&#x27;t retrospectively make a measurement traceable.

Human Rights Council in Geneva said the West could learn from his country’s program of vocational training. “If you do not say it’s the best way, maybe it’s the necessary way to deal with Islamic or religious extremism, because the West has failed in doing so,” said Li Xiaojun, the director of publicity at the Bureau of Human Rights Affairs of the State Council Information Office.<p>&gt; The Chinese government has been trying to change the ethnic balance by shifting members of the majority Han Chinese into the region. [...]<p>&gt; Photos of ancestors and prayer mats usually on display in Kazakh homes were all gone. They were “burned,” the locals told him. “These items,” he said, “were replaced with photos of the Chinese president and Chinese flags.”<p>As someone unfamiliar with the situation, a question I still have is whether this is something unique or unusual for the Chinese government, or how they&#x27;d treat any other mass of people following some organized ideology or creed they saw as competing with their totalitarianism.<p>E.g. I&#x27;ve heard about their efforts to shift the ethnic balance in Tibet, has that been followed-up with similar indoctrination efforts?</text></comment> |

A contemporary user can certainly combat these feelings by the comforting information that LSD is a widely used, and well studied chemical, and the effects are non-lethal and presenting in their proper manifestations.<p>For Hofman, this was not the case. It must have been extremely concerning to be without this information. The complete alteration of the perception of all of his senses, no information about the duration or magnitude of the event, and unsure if he had been fatally poisoned.<p>Given his initial experience, it is amazing that he persisted the way he did.</text></comment> | <story><title>Albert Hofmann discovers the effects of LSD (1943)</title><url>http://laphamsquarterly.org/intoxication/exploring-alternate-universe</url></story><parent_chain></parent_chain><comment><author>MichaelGG</author><text>I read <i>LSD: My Problem Child</i>. Interesting, short, book. At one point, Sandoz was giving out samples to anyone who asked, as they were hoping someone would find a good commercial use. Timothy Leary went and ordered 10 grams (which is 100,000 x 100ug doses), but apparently Princeton(?) didn&#x27;t back him up or there was some importing issue, and by that time Sandoz started getting suspicious and stopped sending out samples. Oops.<p>It&#x27;s probably due to the reckless behaviour of early users that LSD got such a bad rap and banned so hard. Not that they should have had to been responsible -- they shouldn&#x27;t be blamed for stupid government actions -- it&#x27;s just an unfortunate thing. And early proponents weren&#x27;t very rigorous and came up with fantastical claims, greatly exaggerating LSD&#x27;s capabilities. It&#x27;s still great stuff, just not quite a magical cure-all. Also I&#x27;m guessing most ethics systems would have issues with dosing people without their knowledge&#x2F;consent.<p>The book also talks of later trips to Mexico where they did mescaline I believe. And how the images they saw, the shapes and patterns, looked exactly like Aztec art.</text></comment> |

Can you name a company that has actually been doing this better?<p>For instance, they often resist new technologies like high refresh rate or OLED screens, 5G, etc., until they feel the technology is developed sufficiently and won’t impact battery life. There are other brands that compete by making a list of features rather than a coherent product.<p>Of the examples you named, both the Touch Bar and the butterfly keyboard are gone now, and the latest Macs are the best Macs ever. That shows a willingness to try new things, while also showing that they have good judgement in the long term and a willingness to move away from what doesn’t work.<p>Also, the iPad and Apple Watch haven’t been as important to Apple as the iPhone, but they are still original and category-defining products that I would call innovative. Not every new product needs to double your company’s market cap to be a big success in the category.</text></comment> | <story><title>The Google incentive mismatch: Problems with promotion-oriented cultures</title><url>https://www.warp.dev/blog/problems-with-promotion-oriented-cultures</url></story><parent_chain><item><author>lisper</author><text>Another former Googler here (from waaaaaaayyyy back -- I was employee #104).<p>The reason Google is the way it is, and many organizations are the way they are, is that they are trying to reproduce the circumstances that led to their initial success.

Cuil tried, and they had a huge spike in traffic at launch. Then people discovered the product was broken. Also, they didn&#x27;t have a revenue model. They were able to build a full search engine with about 50 people and $50M, which indicates the price of entry isn&#x27;t that high.<p>Over time, hardware gets cheaper, and the cost of building a search engine declines. This has not been matched with a reduction in ad density. The cost improvement is going into Google&#x27;s profit margin. That indicates a vulnerability.<p>Google has some striking weaknesses. The two I focus on are provenance and business background. I&#x27;ve done work on business background (see &quot;sitetruth.com&quot;). That tries to find the real-world business behind a web site that&#x27;s selling something, and then uses the data available about real-world businesses to check it out. That can then be fed into search result ordering. SiteTruth is a demo; it&#x27;s running off free data sources. Paying for higher quality data from Dun and Bradstreet and other non-cheap sources would make the business background check much better.<p>Google&#x27;s other big weakness is provenance. Search engines should find the original source of information. Much of the Internet is sites scraping other sites, linking to other sites, and commenting on other sites.

And they continue to cannibalize themselves by making ads more and more indistinguishable from normal search results. I&#x27;m sure that&#x27;s made them a lot of money in the short-term, but everyone now knows they can&#x27;t be trusted, as quality is no longer sacred (which was its main appeal back in the early days!). They are now in the same category of pedestrian ad peddlers as Facebook and Twitter.<p>Therefore a competing product doesn&#x27;t need to be as good as current Google, only as good as it used to be. Still hard, but far from impossible for someone with money.<p>What may be harder is Cuil&#x27;s second problem as mentioned: Finding a revenue model. You can&#x27;t compromise your data by manipulating searches (lessens quality) and you can&#x27;t compromise your integrity by prioritizing ads (lessens trust). I&#x27;m sure a lot of people would pay big money for the answer, which no one seems to have (as demonstrated by Twitter&#x27;s descent into ad trickery such as camouflaging the ad disclaimers).</text></comment> | <story><title>Frighteningly Ambitious Startup Ideas (2012)</title><url>http://www.paulgraham.com/ambitious.html</url></story><parent_chain><item><author>Animats</author><text>I&#x27;m surprised that someone hasn&#x27;t taken on Google in search. Cuil tried, and they had a huge spike in traffic at launch. Then people discovered the product was broken. Also, they didn&#x27;t have a revenue model. They were able to build a full search engine with about 50 people and $50M, which indicates the price of entry isn&#x27;t that high.<p>Over time, hardware gets cheaper, and the cost of building a search engine declines. This has not been matched with a reduction in ad density. The cost improvement is going into Google&#x27;s profit margin. That indicates a vulnerability.<p>Google has some striking weaknesses. The two I focus on are provenance and business background. I&#x27;ve done work on business background (see &quot;sitetruth.com&quot;). That tries to find the real-world business behind a web site that&#x27;s selling something, and then uses the data available about real-world businesses to check it out. That can then be fed into search result ordering. SiteTruth is a demo; it&#x27;s running off free data sources. Paying for higher quality data from Dun and Bradstreet and other non-cheap sources would make the business background check much better.<p>Google&#x27;s other big weakness is provenance. Search engines should find the original source of information. Much of the Internet is sites scraping other sites, linking to other sites, and commenting on other sites. We see this on HN all the time, where someone links to an article, but the actual source is two blogs deep. The original source should be the primary search result, perhaps annotated with notes about the more heavily promoted sites mentioning it.

I.e. I know I want a page from stackoverflow, or Wikipedia, or arxiv, or Reddit, or Yelp but rather than navigating to those sites I just cmd+T in Chrome, type keywords, and scroll to the site&#x27;s link on the result page which is almost always at the top anyways.<p>I&#x27;m sure others use Google like this too (varying on your culture&#x27;s go-to sites), so does it even need to exist as it does right now? I could imagine a new app that indexes just within this band of sites. And Google or some other app is relegated to &quot;the rest&quot; for rare occasions.</text></comment> |

The filer was arguing that the ai created the work on its own as a work for hire and thus the ai was the author with the computer scientist merely being the owner of the copyright as it was made for hire. I don’t think the argument that ai is a tool and the human operating it is the author was considered because the filer explicitly didn’t want to consider it.<p>In the review being appealed here (<a href="https:&#x2F;&#x2F;www.copyright.gov&#x2F;rulings-filings&#x2F;review-board&#x2F;docs&#x2F;a-recent-entrance-to-paradise.pdf" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.copyright.gov&#x2F;rulings-filings&#x2F;review-board&#x2F;docs&#x2F;...</a>). It makes it clear that the computer scientist doing the filing was trying to argue this was a work made for hire with the author being the computer. They wanted to argue that copyright can be assigned to non humans, but that just isn’t how the law works. The summary makes it clear early that it’s just taking their word that the work had no human input and was thus purely the creation of the computer.

Our fiscal deficit is already $3 trillion this year and it&#x27;s only April. This is a recipe for disaster. How much of corporate America will the Fed own when this all comes crashing down? Will we have a nationalized economy by default?</text></comment> | <story><title>Seen everywhere in last U.S. crisis, moral hazard is nowhere in this one</title><url>https://www.reuters.com/article/idUSKCN21U0GV</url></story><parent_chain><item><author>davidxc</author><text>The statement about the lack of inflation from QE and other stimulus programs from 2008 is pretty questionable. There&#x27;s been little inflation as measured using usual consumer price indices, but the construction of those indices is typically fairly focused on consumer goods and underweights the assets that rich people tend to invest in (stocks, real estate, bonds, etc).<p>The QE and stimulus programs from 2008 were significantly more targeted toward the upper and upper-middle classes (arguably without that much trickle-down), and so there wouldn&#x27;t be much significant inflation as measured by consumer price indices.<p>But if we look at the assets that rich people invest in (since it&#x27;s mostly wealthier people who benefited from the 2008 stimulus programs), then I&#x27;d say there&#x27;s been a significant amount of inflation - P&#x2F;E ratios for stocks have been historically high in the last few years, real estate in desirable cities has gotten significantly more expensive, and bond yields have been low.<p>We seem to be already seeing some of the same, with the stock market being pushed up by the Fed&#x27;s commitment to 4T+ in stimulus this time around and ever lower interest rates.</text></item></parent_chain><comment><author>grey-area</author><text>We&#x27;re about to find out what global QE to infinity does.<p>I&#x27;d expect more events like the recent boom in stock prices in spite of massive global unemployment and the wave of unrest nicknamed the Arab spring which came after 2008 and had origins in economic disruption. Revolutions often come after the unbearable has passed.<p>Even if we quickly overcome the virus the global economic impact of the lockdown and QE will be severe and long lasting. It&#x27;s quite possible that due to QE&#x2F;stimulus none of that will show up in stock prices and they will shoot up, boosting inequality again.</text></comment> |

As an introvert, chatting or small talk isn&#x27;t really a chore, and I waste enough of my own time on my own time, so what&#x27;s a few words with a stranger?<p>That said, it should be considered perfectly acceptable to signal that you don&#x27;t want to stay engaged in a conversation if it&#x27;s someone trying to explain their theory on building a perpetual motion machine. That actually happened. I did not want to stay in that conversation. But even extroverts don&#x27;t like dealing with crazy.<p>It only becomes a chore when the talking itself is <i>the work</i>, such as dealing with Comcast charging you for a modem you totally did return, or dealing with the hospital when they incorrectly billed your health insurance and now they&#x27;re trying to make you pay for the difference.</text></comment> |

You'd have to shut the lid and re-open it for it to wake again.<p>I also had the infamous ghosting issues, though my LG panel was decent enough that I put up with it for a few months. Luckily, when I took it in to get the entire upper clamshell replaced, there was a new part number in stock literally the day before that had apparently resolved the problem.<p>I've purchased a dozen or so MacBooks since the original Unibody and countless iPhones, iPads and other minor Apple products — it is my opinion that engineering quality has gone down over the past two years considerably.<p>As for the issue TFA refers to - it does not plague my 2012 rMBP and I'm sure Apple will, sooner or later, issue a patch to fix it.

While it was generally OK to use, Java in Play is definitely a second class citizen compared to Scala. Most documentation (which btw is sorely lacking) concerns how to do stuff with Scala and you&#x27;ll have to figure out how to do the same in Java yourself.<p>Even worse, breaking backwards compatibility between even minor releases seems to be standard for this framework. So once you&#x27;ve finally managed to find some piece of documentation from some random source on the net (as again, the official documentation is pretty much a joke) you&#x27;ll find that it doesn&#x27;t work at all because it was written with Play! 2.0 in mind which is different from 2.1 which is different from 2.2 and so on.<p>Once you figure it out, it&#x27;s a pretty nice framework. It&#x27;s a shame so little attention seems to be paid to exposing that in a better fashion.</text></comment> | <story><title>An Opinionated Guide to Modern Java Development, Part 1</title><url>http://blog.paralleluniverse.co/2014/05/01/modern-java/</url></story><parent_chain><item><author>twistedpair</author><text>How&#x27;s Play! compare to Spring?

Guice or picocontainer work well, but you can achieve the same effect by using spring&#x27;s Java configuration and avoiding silly things (AOP, shudder), and that way you can migrate existing spring XML piece by piece.<p>If you&#x27;re writing an actual webapp (i.e. something that outputs html) then I highly recommend Wicket; it&#x27;s the most beautiful framework I&#x27;ve ever used, in any language. If it&#x27;s just REST APIs I can&#x27;t really recommend anything - by the time I started writing those I&#x27;d switched to Scala (in which Spray is wonderful).</text></comment> |

We&#x27;re near a freeway, but it&#x27;s not the only culprit. The freeway is either silent or quite noisy depending on ambient weather conditions.<p>But when the cars open up, it sounds like a racetrack.

You may write the essay and just publish it, but in most cases you do some research and at least proofread it once. And again the blogging UI is optimized for this: you have an empty page, nothing other than your written content.<p>And they really complement each other: you talk to people to get ideas for your essays, and you write essays to share your ideas with people and use them as the base for your writing.

Took me 9 months to find a gig a couple years ago when I was looking. Now to be completely honest that&#x27;s also because I can afford to be pretty picky at this point and I was only applying for stuff that looked really interesting. And if it looked like there was just too much bullshit I wasn&#x27;t interested. When you hit your 50s you&#x27;ve seen a lot of bullshit in your time and can smell it a mile away. So yeah, it works both ways. There&#x27;s definitely ageism, but many of us who are aged have saved up enough so we are also picky about what we want to take.<p>I&#x27;m currently between gigs again (previous contract may come back when they get funding so I&#x27;m kind of biding my time because that was a good place to work and good places to work can be hard to find). I don&#x27;t want to call it quits and retire just yet, but I&#x27;m finding less and less that&#x27;s non-bullshit out there these days.

If AMD is willing to pay $1 and Apple is willing to pay $1.01, you make more profit selling to Apple. However, as this article shows, you might end up losing the other business if you offer Apple such preferential treatment. If Apple isn&#x27;t going to use all of your capacity year-round, you don&#x27;t want to alienate the other companies whose orders you rely on.<p>I think Apple likely has to pay a significant premium for getting access to the latest and greatest to the detriment of competitors. It&#x27;s not in TSMC&#x27;s interests to become too dependent on Apple. If AMD and Qualcomm mutiny and their orders start boosting Samsung&#x27;s foundries with more money for R&amp;D, TSMC could find itself 1) competing against a better-funded Samsung foundry; 2) with one customer that now has leverage over TSMC and getting paid less.<p>If AMD and Qualcomm move all their orders to Samsung, it provides Samsung with the money to reinvest in its chip business. If they&#x27;re able to make long-term commitments to Samsung, that&#x27;s bad for TSMC since it will allow Samsung to invest knowing it will make a profit (just as TSMC has been able to do that with Apple&#x27;s commitments).<p>Likewise, if the two other giant chip design companies move to Samsung exclusively, that leaves TSMC in a tough negotiating position with Apple. Before, Apple would have to compete against AMD and Qualcomm for capacity. Now if AMD and Qualcomm have made long-term commitments to Samsung, TSMC becomes really reliant on Apple and Apple will know that TSMC has capacity they can&#x27;t sell elsewhere. Sure, MediaTek and others exist, but it swings the power away from TSMC and toward Apple. Let&#x27;s say that Apple was using 40% of TSMC&#x27;s capacity, AMD 25%, Qualcomm 25%, and MediaTek 10%. Now AMD and Qualcomm make long-term commitments to Samsung. Apple knows that TSMC&#x27;s orders have dropped 50% and that gives Apple a lot of power.<p>Giving Apple the best to the detriment of AMD, Qualcomm, and others is a risky play for TSMC. They&#x27;ll definitely want to be getting very well compensated for it, not merely slightly more. They&#x27;ll want to make sure that what Apple is offering is enough to offset the substantial risk of angering competing chip design companies who might look for fabs elsewhere.</text></comment> | <story><title>TSMC “Apple-first” 3nm policy leads to AMD and Qualcomm mutiny</title><url>https://www.club386.com/tsmc-apple-first-3nm-policy-leads-to-amd-and-qualcomm-mutiny/</url></story><parent_chain><item><author>rob74</author><text>They don&#x27;t have to buy TSMC a fab, they simply have to pay (slightly) more than other TSMC customers - and Apple with its uniquely high margins can afford to do just that.

The idea is that with lower interest rate, companies and people will be more likely to borrow money to spend and that will boost the economy.<p>I for one do not really believe this to be true. I suspect it&#x27;s the act of lowering rates that gives a <i>temporary</i> boost until things rebalance. In other words, economic activity has some dependence on the derivative of interest rates. This is why things were so good from 198x through 2003 or so, rates were dropping the entire time (filtered of course).</text></comment> |

It&#x27;s well intentioned, but the intentions aren&#x27;t to ensure that America can keep up with a rising China.<p>It&#x27;s shocking to me that people in California aren&#x27;t more worried about this. About 15 years ago, I was talking to an engineer at Juniper&#x2F;Cisco. We were joking about how Huawei had copied one of their router designs down to the silk screened assembly instructions (in English!) on the PCBs. Fast forward to today, Huawei is making fully custom equipment down to state of the art switch and router chips, and Chinese companies are white boxing lower end products made by American brands.<p>There&#x27;s a big bet out there that the U.S. can survive on software and social media alone. I would think the success of Tik Tok would have blown even that rationalization out of the water.<p>On the general point of U.S. math education: my cousin who lives in a nice California suburb was complaining that the math education her early high school student is receiving is several grade levels behind what she got--in Bangladesh. My mom, who also went to school in Bangladesh (in the 1960s!) was deeply unhappy about the math education in our affluent Virginia suburb, until I got into a top STEM magnet high school. My own kids go to an expensive private school, but are still getting math tutoring on the side. Math is just a shockingly low priority for Americans.</text></comment> | <story><title>An update on the campaign to defend serious math education in California</title><url>https://scottaaronson.blog/?p=6389</url></story><parent_chain><item><author>kurthr</author><text>From the original letter:<p><pre><code> While well-intentioned, we believe that many of the changes proposed by the CMF are deeply misguided and will disproportionately harm under-resourced students.

Some of the underlying beliefs:<p>1. Blank slate - All humans are of equal ability<p>2. Any observable differences between humans are merely the result of social factors<p>3. Any observable differences in outcomes between groups of humans are the result of oppression from the majority group<p>4. If you observe differences at your org&#x2F;institution, it&#x27;s your moral duty to create policies which disfavor groups of humans performing better and to favor groups of humans performing worse, as those performance differences are due to oppression.<p>If these beliefs undergird your worldview, and your social groups&#x2F;information environment reinforce and reward these beliefs, it is of no surprise that we&#x27;ll see a lot of people soberly propose the types of policies we see here.

Some comments suggest cnc router but simple part like that with the right set of woodworking tools could be made in a couple of minutes freehanding it or maybe using paper template glued to a piece of wood. Also maybe the 3d printer was busy printing the other more complex parts which actually benefit from it. Different tools have different advantages for different parts.</text></comment> | <story><title>Ink/Stitch</title><url>https://inkstitch.org/</url></story><parent_chain><item><author>jstanley</author><text>Seems strange to go to the trouble of making them out of wood when there&#x27;s evidently a 3d printer available.</text></item><item><author>bennyp101</author><text>100% OT - but the wooden cable grips on the DIY Embroidery Machine tutorial really appeal to me!<p><a href="https:&#x2F;&#x2F;user-images.githubusercontent.com&#x2F;44113605&#x2F;47873925-215c9900-de1b-11e8-9f2e-0598991a7ad3.JPG" rel="nofollow">https:&#x2F;&#x2F;user-images.githubusercontent.com&#x2F;44113605&#x2F;47873925-...</a></text></item></parent_chain><comment><author>bennyp101</author><text>Maybe one of those bored days and turn out a load of 1&#x2F;2&#x2F;3&#x2F;4 cable grips to live in a box for the next project</text></comment> |

Her explanation is simple: smart women don&#x27;t go into teaching anymore because they have vastly better options than having to chose between nursing vs teaching. Something to consider since labor can only be as good as the pool of candidates allows.</text></comment> | <story><title>IQ decline and Piaget: Does the rot start at the top?

I have an Android app out there (and more on the way). I work with my girlfriend as kind of a team on Android stuff. We needed to implement an "action bar" kind of like the Android twitter app has up top. I saw a horizontal bar with two buttons. She kept insisting I dig through some of Google's open source implementations and go rip out some random code that I didn't write and don't yet understand and try to get it to work properly with my code. She was convinced this was the only right thing to do.<p>I refused. Whipped up some basic UI XML in a couple minutes with two images buttons for the actions. Done. While many people tweak and tweak, our app is out there. Nobody would know the difference between the official bar and my completely idiot-proof implementation.<p>All this kind of reminds me of a twitter post I made a while back when reading an argument here on HN: <a href="https://twitter.com/BeyondHostile/status/20922938324688896" rel="nofollow">https://twitter.com/BeyondHostile/status/20922938324688896</a></text></comment> | <story><title>How to program independent games</title><url>http://the-witness.net/news/?p=1004</url><text></text></story><parent_chain></parent_chain><comment><author>MetallicCloud</author><text>An excellent talk, but the thing that I disagree with is his defense of having functions with thousands of lines of code in them.<p>It's true that breaking up a function into smaller ones just for the sake of it doesn't make sense, but if you have a function that needs to be over 1000 lines in the first place, it makes me think that the code wont be very reusable in future projects.</text></comment> |

Why is lisp always rejected?<p>I started programming seriously (for money) in 2009, and when we needed a language we went with python because it had better math&#x2F;science libraries than Java and much more libraries in general than clojure&#x2F;lisp&#x2F;ocaml. I confess I like the functional languages and like using some of their features in python.<p>Was the no-libraries dealbreaker for the &quot;pure&quot; functional languages also true in 1999, which led google to java? Or maybe there are complex meta-programming bugs you can generate in the functional languages (and elsewhere) that are the dealbreaker? Or what?</text></comment> | <story><title>Lisping at JPL (2002)</title><url>http://flownet.com/gat/jpl-lisp.html</url></story><parent_chain></parent_chain><comment><author>proximitysauce</author><text>I really feel like they should teach LISP in elementary school.

Whatever it is, pick something physical, grounded, and engrossing, where you can put a bunch of time and effort in, to achieve a real change of pace.<p><pre><code> If they think you&#x27;re crude, go technical; if they think you&#x27;re technical, go crude.
