United States: We removed 39 Facebook accounts, 16 Pages, two Groups and 26 accounts on Instagram for violating our policy against coordinated inauthentic behavior. This network originated in the United States and focused on a number of countries including Afghanistan, Algeria, Iran, Iraq, Kazakhstan, Kyrgyzstan, Russia, Somalia, Syria, Tajikistan, Uzbekistan and Yemen. The operation ran across many internet services, including Twitter, YouTube, Telegram, VKontakte and Odnoklassniki. It included several clusters of fake accounts on our platforms, some of which were detected and disabled by our automated systems prior to our investigation. The majority of this operation’s posts had little to no engagement from authentic communities.<p>We found this activity as part of our internal investigation into suspected coordinated inauthentic behavior in the region. We’ve shared information about this network with independent researchers at Graphika and the Stanford Internet Observatory, who have published their findings about this network’s activity across the internet on August 24, 2022. Although the people behind this operation attempted to conceal their identities and coordination, our investigation found links to individuals associated with the US military.</text></comment> | <story><title>Meta’s Adversarial Threat Report, Third Quarter 2022</title><url>https://about.fb.com/news/2022/11/metas-adversarial-threat-report-q3-2022/</url></story><parent_chain></parent_chain><comment><author>cstejerean</author><text>* US: 39 accounts

A quick Google search turned up revenue of $24 million in 2013. 2014 and 2015 numbers did not come up on my quick search, but I&#x27;d imagine based on the amount of advertising they do it&#x27;s at least held steady. And then there&#x27;s the many millions of investment dollars they received before that. $2 million is not even a slap on the wrist. It&#x27;s like blowing in their ear gently.<p>As far as Lumosity believing their own claims, first this is not a mom and pop store. They have the resources to know for sure whether or not it&#x27;s true, and they have a duty to find that out before making claims. Second, I don&#x27;t buy it. Anybody with half a brain knows it&#x27;s baloney.<p>Lastly, as far as I can see they&#x27;re not being forced to make amends to the customers they ripped off, nor to make public apologies for false claims AND if they can gin up some bullshit study to support their claims (shouldn&#x27;t be hard with their resources), they can continue making them.<p>Also the whole time this lawsuit has been going on, I&#x27;ve been hearing claims that don&#x27;t differ much from the ones in violation on NPR constantly. Just enough to skirt the law.<p>Heavy handed my left foot.</text></comment> |

(not having me in person forces people to think about and write down exactly what they want to say or ask before they actually say it)<p>- My home setup is significantly nicer than my office set up.<p>- Open office means I hear all about everyone&#x27;s past or upcoming weekends, vacations, etc.<p>- I enjoy stretching or doing small exercises throughout the day, which is super weird to do while in the office (plus no yoga mat).<p>- People low key hate me because I am the only person with a mechanical keyboard and make lots of noise when I start typing a lot. (I&#x27;ve learned to ignore the not so subtle stare downs)<p>So probably my biggest thing is the open office problem.

Why do you presume to know more about the VC funding process and it's outcomes than Joel? You've run a successful business and you manage a great open source framework. That's to be commended. You chose to not take VC, and you have been successful. Congratulations.

The whole idea of getting VC money is to jumpstart the next phase of a company/product's life. Facebook was a college kid's side project that looked promising but VC money made it top 3 site on the web. YouTube would have been impossible for 3 typical 20-somethings to afford out of their personal/family savings. They needed VC funding because they were burning through $1m/month in cash. What exactly is it about Stack Overflow that Joel can't pay for himself with his own funds? What kind of hiring does he want to do to make it any bigger?<p>Joel listed all these vague reasons that sort of sound good without actually saying concrete steps / changes that would come out of VC funding. I would definitely like to hear what it is that he, despite being one of the most popular tech bloggers with a boatload of notoriety and savings, can't do with Stack Overflow that somehow VC money can.</text></comment> |

I think the “struggle” really does make people value things and others more highly and the lack thereof less.<p>My working hypothesis is our brains are always learning - literally everything. We learn our concept of time from our experience with it. We learn our concept of a relationship with another person from our experience with them. If someone comes into our life easily - relative to other relationships - our brain associates them with less value. It’s also horrible logic.<p>Edit- as for whether someone likes you: people accept, overlook, and tolerate more aberrations from normal&#x2F;good treatment from people they value or like. If they’ll accept little of your aberrations then they’re unlikely to ever like you - run for the hills.

They filled the room and presented me with a fairly expensive bottle of whiskey.<p>I&#x27;ve had a few girls tell me, after it was too late, that they always had a crush on me. Well, I was interested in them, too.<p>If someone would have just said something sooner, life, for me, would be totally different now.</text></item></parent_chain><comment><author>jacobolus</author><text>&gt; <i>Every single guy I have ever gushed at about how keen he is has, without fail, promptly turned into a psycho asshole monster and made me wish I never met him.</i><p>I have seen &#x2F; heard of many guys getting complimented over the years (including myself a few times), and never heard of one of them turning into a “psycho”, “asshole”, or ”monster”. A couple times I saw a guy get complimented out of the blue and then kind of stammer something and hurry away looking embarrassed, because he didn’t have any idea how to respond. A couple times I have seen men brush off &#x2F; refuse compliments it looked like because they wanted to seem modest (e.g. “oh it was really no big deal, please don’t think anything of it...” after someone had just directly said their action was very helpful&#x2F;meaningful). Once I saw a guy get complimented and respond “yeah, everyone says the same thing”, which I admit is a pretty obnoxious response.<p>I have also heard plenty of stories of guys who were monsters (physical abusers, stalkers, spreaders of nasty rumors ...), but to my knowledge none of those came out of a compliment.<p>I believe you, but I’m having trouble imagining quite what happened. Maybe you can elaborate a bit? Do you mean that those men turned around and demanded something more from you? Stopped treating you with basic respect? Wouldn’t talk to you anymore? Chased you around? ...</text></comment> |

Shine was a life saver when I was building the live broadcast capability of othernet.is.<p>Our Satellite link was really low bitrate ( less than 20kbps). I wanted to keep as much of that as possible for the data-casting part, which was our core offering. So after experimenting with varioud codecs I narrowed down to using Opus@8kbps as my downlink from the satellite to our custom receivers. The problem was, Opus wasn&#x27;t natively supported as a codec by most browsers (Safari being a major culprit). In fact after analysis, I found the only format that could be reliably played on every browser (including mobile) is mp3. So the solution I derived was to have the downlink in opus, decode that on the reciver, reencode it to mp3, and stream that out to the users browser. Now the reciever was a very low end linux device - 1GHz Arm6, 256MB ram - that ran the entire stack. Satellite receiver, UI server, filesystem maintenance, Wifi Hotspot (softAP). We also didn&#x27;t want to load it down with large heat sinks or fans as a design goal. So the cpu could not be loaded to its full capacity. Every other MP3 encoder I tried was too heavy duty, and would cause thermal issues for the SoC. But Shine worked perfectly - total cpu consumption remaining less than 10% for real time decoding (from opus) and encoding (to mp3).</text></comment> | <story><title>Shine: A super fast fixed-point MP3 encoder</title><url>https://github.com/toots/shine</url></story><parent_chain></parent_chain><comment><author>duskwuff</author><text>And for the other direction, there&#x27;s minimp3: <a href="https:&#x2F;&#x2F;github.com&#x2F;lieff&#x2F;minimp3" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;lieff&#x2F;minimp3</a><p>I&#x27;ve used minimp3 to implement a MP3 player on a STM32 microcontroller.

A simple change, like removing indirection in our list, was an order of magnitude improvement in our latencies since there’s memory prefetching in the compiler and the CPU can anticipate which vectors are going to be loaded next in order to improve the memory footprint.<p>This is a common experience and I&#x27;m still surprised by the choice I constantly see to use a managed-memory languages to build a database - one of a very small set of special cases where having full control over the memory layout might just be a reasonable thing to want. In this universe (absent doing something completely absurd) it&#x27;s not algorithmic complexity but managing data locality in the cache hierarchy (e.g. reading things from L3 vs main memory vs disk) that makes things orders of magnitude faster, especially if you&#x27;re in the realm of doing things like SIMD operations to speed things up.<p>Perhaps there&#x27;s some level of suck we&#x27;re willing to tolerate for all the other benefits you get, but I&#x27;ve been noticing a pattern of &quot;align things just so at the higher level and hope they mostly turn out the way you want at the lower level&quot; (e.g. also with the Apache java-y databases like hadoop &#x2F; hbase &#x2F; cassandra which I guess were mostly supposed to derive their total throughput from massive scale rather than per-node performance) which is a bit funny.<p>But also it seems like part of Rust&#x27;s promise was &quot;low level but make it high level&quot; which seems to be succeeding (zero-cost abstractions and whatnot), so I imagine this will get better over time - having not attempted a project like this myself, I&#x27;m not sure what the limitations you&#x27;d run up against are in terms of laying things out in memory in a favorable way - I imagine the kind of massive manually managed arena allocations and ad-hoc pointers going everywhere that one normally does doesn&#x27;t really fly.</text></comment> | <story><title>Rewriting a high performance vector database in Rust</title><url>https://www.pinecone.io/learn/rust-rewrite/</url></story><parent_chain></parent_chain><comment><author>einpoklum</author><text>The authors of this post rewrote _their own_ DBMS in Rust. Which is perfectly ok, but I&#x27;m not sure I would trust them to decide that theirs is a &quot;high-performance&quot; DBMS. They don&#x27;t have any benchmark results except images of their own internal performance measures; they don&#x27;t offer any way of comparing their performance with other DBMSes (e.g. Vectorwise&#x2F;Actian Vector, ClickHouse, DuckDB etc. - not to mention Oracle, MS or SAP offerings); and they only have marketing blurb about their numbers: &quot;Up to 10x performance&quot; (with no baseline of course).<p>So, they took some DBMS (which is probably not so hot in terms of performance) and rewrote it in Rust. Surely possible, possibly useful, but not much to write home about if one is interested in DBMS performance.</text></comment> |

So they still don&#x27;t have only about a 2&#x2F;3 output compared to the very same manufcaturing plants based in Germany.<p>While Asian companies have much higher working culture than Germany, I assume the experience at first is horrible for the Asian managers.</text></comment> |

Who demos in that case?<p>And what would be wrong with a manager demoing a product that was built by a team he&#x2F;she manages? It seems to imply that the manager should have no sense of ownership, but a good manager is absolutely crucial to the success of a project. Taken to the extreme, it would imply a CEO of a company could never demo a company product he didn&#x27;t &quot;build himself&quot;.</text></comment> |

Sure this won&#x27;t happen overnight...<p>But my theory with petroleum is that it has so many HUGE economies of scale built into its production that a demand collapse will send it into a rapid tailspin.<p>A small version of this happened in the Dakotas when the Saudis started dumping oil to get it under a price, and the North Dakota oil industry collapsed. That was due to intentional oversupply, not necessarily due to collapsed demand.<p>But so much of the oil market is now pretty expensive extraction: tar sands, shale oil, fracking, deep offshore. The easy stuff is gone. That to me means that the industry rests on a certain price, and if it falls under that, the industry can&#x27;t sustain it.<p>I think the big thing in this reverse economies of scale, where costs rise as the industry shrinks (and absorbs writeoffs) is that finance, already somewhat intimidated by the growing pressure to divest from fossil fuels, will rapidly abandon it once it becomes extremely risky due to collapsing demand and massive migrations of transportation modes to electric.<p>It&#x27;s all vague decade-away prognostication, but you&#x27;ll start hearing the violins playing for oil companies when some combination of this happens:<p>- charging infrastructure builds out (2 years to catch the current Tesla supercharger, probably another 5 years to get some semblance of every-50-miles availability)<p>- LFP chemistry hits a power density of somewhere around 200-250wh&#x2F;kg (LFP is really cheap and has far less materials restrictions from cobalt) (probably in 1-2 years for mass production)<p>- various solid state technologies hit production (looks unlikely for 5 years)<p>- EV drivetrain cost (battery, motors, cooling, case, management systems, etc) drops to 2&#x2F;3 of ICE (probably another 4 years)<p>- a carbon tax, a more substantial EV subsidy<p>The floor will rapidly fall.<p>I&#x27;m not saying Tesla isn&#x27;t insanely valued.

Sure, <i>if</i> society collapses and all records of these waste locations are lost, and <i>if</i> some future civilization decides to dig a mile deep in a remote area with no natural resources, and <i>if</i> they decide to crack open these concrete caskets because all knowledge of 21st Century languages are lost so they can&#x27;t read the warnings, and <i>if</i> they manage to do all this without knowledge of radiation then humans might get contaminated.<p>By comparison, CO2 emissions get pumped straight into the atmosphere<p>&gt; It is indeed a significant accomplishment. Let&#x27;s keep it that way by ceasing operation on time and not risk tarring the accomplishment with a reactor failure.<p>Yeah, and then turn around and build more coal and gas plants because the other alternatives cannot provide consistent power at the same price point. This is what happened in Germany and Japan. Anti-nuclear runs contrary to the principles of clean energy. In fact some estimates indicate that the coal plants built in Japan following the reactor closures after the Fukishima Daichi plant failure will actually end up emitting more radiation than the incident itself.</text></comment> | <story><title>Pictures show cracks in Ayrshire nuclear reactor</title><url>https://www.bbc.com/news/uk-scotland-47485321</url></story><parent_chain><item><author>einpoklum</author><text>1.

Superhero movies have tons of drama — the whole storyline typically lives solely to create character growth and personal shifts, and otherwise is largely irrelevant (if the characters don’t learn some lesson, they’ll never succeed).

Rheya, for example, says, &quot;I&#x27;m not the person I remember. I don&#x27;t remember experiencing these things.&quot; And later, &quot;I&#x27;m suicidal because that&#x27;s how you remember me.&quot; In other words, Kelvin gets back not his dead wife, but a being who incorporates all he knows about his dead wife, and nothing else, and starts over from there. She has no secrets because he did not know her secrets. If she is suicidal, it is because he thought she was.</i><p><i>The deep irony here is that all of our relationships in the real world are exactly like that, even without the benefit of Solaris. We do not know the actual other person. What we know is the sum of everything we think we know about them. Even empathy is perhaps of no use; we think it helps us understand how other people feel, but maybe it only tells us how we would feel, if we were them.</i><p><a href="https:&#x2F;&#x2F;www.rogerebert.com&#x2F;reviews&#x2F;solaris-2002" rel="nofollow">https:&#x2F;&#x2F;www.rogerebert.com&#x2F;reviews&#x2F;solaris-2002</a><p>I think it is a deep mistake to correlate one&#x27;s exterior appearance and behavior with a sense of selfhood. At best, it&#x27;s a shallow surface imitation of the actual person. At worst, it creates a nightmarish, Uncanny Valley-esque simulacrum, not unlike Harlow&#x27;s wire monkey mother surrogates.

Here&#x27;s one on WebGL.[1] Very impressive demo. But you need most of a GPU to do it.<p>The fountains in GTA V are just playing a short texture animation on repeat, plus a particle effect for water droplets. They have a whole game to run and can&#x27;t devote too many resources to water. GTA V does amazingly well at keeping a large number of active objects moving around.<p>GTA&#x27;s ocean water is quite elaborate. There are waves, you can jet-ski on it, and the effects all work together well. Much more impressive than the fountains.<p>I once briefly met the guy who did the first good water shader, for Softimage. That had synchronized levels of detail, so you could see fine detail close up yet see all the way to the horizon, and the waves matched up.
Not real-time, but it was the 1990s. First used on <i>Waterworld</i>, which didn&#x27;t get that guy any attention.

I find something nice to tinker with, and when my brain goes &quot;ooh, shiny&quot; I stop giving a shit about anyone&#x27;s bottom line.<p>To be fair, it usually turns out for the better for the project and its code base! But sometimes it doesn&#x27;t, and I figure that&#x27;s just the cost of doing business. Companies should be willing to take these kinds of informed risks in order to improve their employees&#x27; ability, and therefore the quality of their product. However, a lot of management only sees the short term gain, because long term gain isn&#x27;t incentivized for them. They just wanna do well and get a promotion.<p>Well, guess what, it&#x27;s the same for me. Except for me to do well, I have to be learning new things constantly.

Lol.)<p>But yes, it’s more complex than simply firing individual contributors for sure and I regret wording my statement that way, but I hope you all can understand the real point that I’m making.<p>Edit: I’d like to point out that, in my anecdote above, in hindsight, if anything, I was probably the one who looked incompetent when the suits started asking the expected questions re the sudden set of new issues, because I did my best to shield that software engineer from them (or at least I’d like to think that I did). I know the feeling of messing up at that level and I knew that he was most likely already beating himself up, so I couldn’t just let him take the fall, or worse, throw him under the bus. These tend to be complex situations in real life!</text></item><item><author>dkersten</author><text>You probably wouldn&#x27;t want to work for somebody who fired people so easily anyway. This is one reason why I find it stupid when people defend companies or are super loyal to their employers: companies don&#x27;t care about you and especially companies that fire on a whim without concern that they&#x27;re fucking with somebodies life.

I&#x27;ve thought about building a datapath on an FPGA that uses partial reconfiguration to synthesize new hardware blocks based on the math being doing at a particular instant, and it sounds like DARPA wants to do that on steroids. Server CPUs coupled with FPGAs are already being used for a lot of interesting things and I think it makes a lot of sense to integrate together even tighter. I&#x27;m also really happy to hear that they&#x27;re funding new EDA software that is actually smart. The best we have right now is some whitelist based rule checking for schematics and layout. I want full simulation, a perfect, proven parts library with symbols, footprints, 3D models, non-ideal SPICE models, and a thermal model for every part in existence, smart rule checking that looks not only for things like unconnected nets, but logic level mismatches and clock edges that are too fast.<p>Little pieces of this exist already, but in my opinion, software for creating hardware is way behind software for creating software.</text></comment> |

It&#x27;s impossible to know which parts of the dynamic environment are used by a module without inspecting its source code. And changes to the module&#x27;s dependencies are not noticed by callers, which may lead to cases where tests fail to stub out particular side effects without anyone noticing.<p>Given this drawback, dependency injection still seems like the better trade-off to me, despite of its higher amount of required boilerplate. Perhaps it is possible to bring some of the explicitness to the dynamic scoping approach, though.</text></comment> | <story><title>Dependency injection is dynamic scoping in disguise</title><url>http://gustavlundin.com/di-frameworks-are-dynamic-binding/</url></story><parent_chain></parent_chain><comment><author>cryptica</author><text>I agree that dependency injection and dynamic scoping are similar and I think they are both anti-patterns.<p>It doesn&#x27;t make sense to stub out dependencies in unit tests (unless you absolutely have to). Stubbing out dependencies is like stubbing out native functions, operators or loops. They are called dependencies for a good reason; because your class depends on them and assumes that they work. Trying to make dependencies substitutable is overengineering and leads to poor design and gives you more work when implementing unit tests.<p>Dependency injection is particularly bad because it makes it difficult to find the path to the dependency&#x27;s source code (which is critical for debugging). Hiding the source path of a dependency is a terrible anti-pattern. When it comes to programming, there are few things more horrible than not being able to determine where some buggy piece of logic is located. I cannot imagine any use case where that would be a fair tradeoff.<p>Any kind of injection of dependencies should be done via an explicit method&#x2F;constructor parameter. Sometimes it means that the dependency instance has to traverse a few classes in the hierarchy, but that&#x27;s way better because at least you can unambiguously track where the dependency came from. Also, if the dependency has to traverse A LOT of classes, then you know there is probably something wrong with your architecture (e.g. a dependency imported too high in the hierarchy and used in a deeply nested class can indicate poor separation of concerns and leaky abstraction between components).</text></comment> |

If you don&#x27;t trust my summary of it, and you consider yourself very, very well-briefed on what Bitcoin is doing under the hood and who the players are in the Bitcoin community, just read the next ~12 hours of logs. It&#x27;s absolutely riveting.<p>My summary:<p>The Bitcoin protocol doesn&#x27;t exist. The only protocol which matters is the actual behavior of the Bitcoin Core client -- the one originally coded by Satoshi, which forms a supermajority of the network. Bitcoin Core released version 0.8 on or about March 11, 2013. This differed from Bitcoin Core 0.7 in at least one respect, which was that 0.7 used Berkeley DB and 0.8 did not.<p>BDB has a configuration issue, specifying the maximum number of locks it can use at once. If you attempt to use more, it returns an error.<p>Here&#x27;s one reason I say the Bitcoin Protocol doesn&#x27;t exist: No sane person says &quot;An important feature of the Bitcoin Protocol is that conforming clients MUST REJECT any Bitcoin transaction which would exhaust the default number of locks available to the Berkeley DB.&quot;<p>Someone submitted a Bitcoin transaction which did, in fact, exhaust the number of locks available to the Berkeley DB. It was conformant with all the rules that Bitcoiners believe transactions have to be conformant with <i>except</i> that bit about the lock limit in the Berkeley DB. This transaction was accepted by a miner running the 0.8 software.<p>Let&#x27;s, for convenience, call the blockchain as it existed prior to that block being mined Blockchain B. The blockchain with that block in it is B&#x27;.<p>Bitcoin Core 0.7 rejected the authenticity of B&#x27;. Accordingly, when 0.8 nodes said &quot;I have a new block to publish! It checks out and builds off of the-present-head-of-B&#x27;&quot;, 0.7 nodes said &quot;I don&#x27;t know what that nonsense you&#x27;re spouting is, but it sure isn&#x27;t Bitcoin.&quot; Bitcoin Core 0.7 nodes and miners continued talking amongst themselves and building B up.<p>Bitcoin Core 0.8 nodes accept the authenticity of B&#x27; and all blocks chained on top of it. If you presented them with a block chained off of the head of B, they would say &quot;Oops, sorry, sucks to be you -- someone already has a longer chain. You&#x27;ve created <i>a</i> blockchain, but by the writ of Satoshi, we only do business with <i>the longest compliant</i> blockchain, which is B&#x27;.&quot;<p>This is called a network split. And it is, in laymen&#x27;s terms, utterly cataclysmic.<p>Here&#x27;s why: Suppose Mt. Gox runs on 0.7 and Coinbase runs on 0.8. I can create a transaction which spends some output(s) $COIN and have it accepted into a B&#x27; block. Perhaps that transaction deposits my $COIN into Coinbase. Since that transaction doesn&#x27;t exist on B, I can then deposit <i>the same $COIN</i> into Mt. Gox. Both Mt. Gox and Coinbase believe themselves to be in possession of the same Bitcoin.<p>And both of them <i>are right</i>.<p>Which is why after that channel figures out what is happening that <i>engineering gets real</i>. After discussions between several core developers they ascertain that the Bitcoin mining cabal behind B&#x27; is small enough to get, well, <i>both</i> of them on Skype and convince them to throw away hours of history on B&#x27; (which is, again, built off the new-and-improved <i>bug free</i> version of Bitcoin) and instead start building off of B instead. Their history must die so that Bitcoin can live.<p>This plan is executed. It works.<p>Read the chat transcript if you don&#x27;t understand this: Bitcoin was virtually unusable during the interim -- most of the merchants people cared about turned off transactions entirely because they were, sensibly, scared shitless. Several hours of transactional history got wiped out. One security researcher <i>successfully executed a ~$10,000 double spend attack against a merchant</i> -- he gave the money back afterwards.<p>Now, you tell me: how do you rate my credibility here versus your friend? My assessment of this event is &quot;Bitcoin has an identifiable governance structure. You can fit them into an IRC channel +&#x2F;- a few Skype sessions. They can independently decide to change the rules of the &#x27;Bitcoin protocol&#x27; a) at will b) retroactively. I cannot reconcile this with claims that Bitcoin is &#x27;does not require trust&#x27; or is &#x27;decentralized.&#x27;&quot;</text></item><item><author>swombat</author><text>Would be interesting to see Patrick&#x27;s answer to the above, particularly the first point... I pinged the tweetstorm to a friend of mine who&#x27;s knowledgeable about Bitcoin and he seemed to feel Patrick was, erm, not particularly believable on this topic.<p>For example, on the first point:<p><i>this is akin to saying the bit torrent foundation closed down bit torrent! waah!</i><p><i>it&#x27;s impossible</i><p><i>once they released the reference implementation, it was out of their hands</i><p><i>this is the beauty of open sourced and decentralised technology, once it&#x27;s out there it&#x27;s difficult to control</i><p><i>the analogy would be Linus going batshit mad and deciding to include binary blob drivers provided by the NSA in the kernel mainline, fine - nobody will use it, business continues as usual using a fork before that and he becomes irrelevant</i></text></item><item><author>0xFEED</author><text>There&#x27;s a number of things in that which aren&#x27;t totally correct.<p>&gt; <i>No, seriously, the decentralized nobody-needs-to-trust-anybody payments network </i>was shut down by an IRC channel&#x27;s consensus* for 8 hrs.*<p>It wasn&#x27;t &quot;shut down&quot; in any sense of the word, the network kept working (in duplicate, no less). It was the decision of two pool owners with extraordinary hashrates to sacrifice their chain (which was actually the &quot;correct&quot; one as far as intentions go), rather than the core developers. Nobody has some magic key to shut down the network (though originally, Satoshi&#x27;s alert key did enable a &quot;safe mode&quot;, this is long gone)<p>&gt; <i>Bitcoin is not a protocol in any meaningful sense of word. It is a single C++ codebase that you have to be bug-for-bug compatible with.</i><p>That&#x27;s the reality of distributed consensus.

If you don&#x27;t trust my summary of it, and you consider yourself very, very well-briefed on what Bitcoin is doing under the hood and who the players are in the Bitcoin community, just read the next ~12 hours of logs. It&#x27;s absolutely riveting.<p>My summary:<p>The Bitcoin protocol doesn&#x27;t exist. The only protocol which matters is the actual behavior of the Bitcoin Core client -- the one originally coded by Satoshi, which forms a supermajority of the network. Bitcoin Core released version 0.8 on or about March 11, 2013. This differed from Bitcoin Core 0.7 in at least one respect, which was that 0.7 used Berkeley DB and 0.8 did not.<p>BDB has a configuration issue, specifying the maximum number of locks it can use at once. If you attempt to use more, it returns an error.<p>Here&#x27;s one reason I say the Bitcoin Protocol doesn&#x27;t exist: No sane person says &quot;An important feature of the Bitcoin Protocol is that conforming clients MUST REJECT any Bitcoin transaction which would exhaust the default number of locks available to the Berkeley DB.&quot;<p>Someone submitted a Bitcoin transaction which did, in fact, exhaust the number of locks available to the Berkeley DB. It was conformant with all the rules that Bitcoiners believe transactions have to be conformant with <i>except</i> that bit about the lock limit in the Berkeley DB. This transaction was accepted by a miner running the 0.8 software.<p>Let&#x27;s, for convenience, call the blockchain as it existed prior to that block being mined Blockchain B. The blockchain with that block in it is B&#x27;.<p>Bitcoin Core 0.7 rejected the authenticity of B&#x27;. Accordingly, when 0.8 nodes said &quot;I have a new block to publish! It checks out and builds off of the-present-head-of-B&#x27;&quot;, 0.7 nodes said &quot;I don&#x27;t know what that nonsense you&#x27;re spouting is, but it sure isn&#x27;t Bitcoin.&quot; Bitcoin Core 0.7 nodes and miners continued talking amongst themselves and building B up.<p>Bitcoin Core 0.8 nodes accept the authenticity of B&#x27; and all blocks chained on top of it. If you presented them with a block chained off of the head of B, they would say &quot;Oops, sorry, sucks to be you -- someone already has a longer chain. You&#x27;ve created <i>a</i> blockchain, but by the writ of Satoshi, we only do business with <i>the longest compliant</i> blockchain, which is B&#x27;.&quot;<p>This is called a network split. And it is, in laymen&#x27;s terms, utterly cataclysmic.<p>Here&#x27;s why: Suppose Mt. Gox runs on 0.7 and Coinbase runs on 0.8. I can create a transaction which spends some output(s) $COIN and have it accepted into a B&#x27; block. Perhaps that transaction deposits my $COIN into Coinbase. Since that transaction doesn&#x27;t exist on B, I can then deposit <i>the same $COIN</i> into Mt. Gox. Both Mt. Gox and Coinbase believe themselves to be in possession of the same Bitcoin.<p>And both of them <i>are right</i>.<p>Which is why after that channel figures out what is happening that <i>engineering gets real</i>. After discussions between several core developers they ascertain that the Bitcoin mining cabal behind B&#x27; is small enough to get, well, <i>both</i> of them on Skype and convince them to throw away hours of history on B&#x27; (which is, again, built off the new-and-improved <i>bug free</i> version of Bitcoin) and instead start building off of B instead. Their history must die so that Bitcoin can live.<p>This plan is executed. It works.<p>Read the chat transcript if you don&#x27;t understand this: Bitcoin was virtually unusable during the interim -- most of the merchants people cared about turned off transactions entirely because they were, sensibly, scared shitless. Several hours of transactional history got wiped out. One security researcher <i>successfully executed a ~$10,000 double spend attack against a merchant</i> -- he gave the money back afterwards.<p>Now, you tell me: how do you rate my credibility here versus your friend? My assessment of this event is &quot;Bitcoin has an identifiable governance structure. You can fit them into an IRC channel +&#x2F;- a few Skype sessions. They can independently decide to change the rules of the &#x27;Bitcoin protocol&#x27; a) at will b) retroactively. I cannot reconcile this with claims that Bitcoin is &#x27;does not require trust&#x27; or is &#x27;decentralized.&#x27;&quot;</text></item><item><author>swombat</author><text>Would be interesting to see Patrick&#x27;s answer to the above, particularly the first point... I pinged the tweetstorm to a friend of mine who&#x27;s knowledgeable about Bitcoin and he seemed to feel Patrick was, erm, not particularly believable on this topic.<p>For example, on the first point:<p><i>this is akin to saying the bit torrent foundation closed down bit torrent! waah!</i><p><i>it&#x27;s impossible</i><p><i>once they released the reference implementation, it was out of their hands</i><p><i>this is the beauty of open sourced and decentralised technology, once it&#x27;s out there it&#x27;s difficult to control</i><p><i>the analogy would be Linus going batshit mad and deciding to include binary blob drivers provided by the NSA in the kernel mainline, fine - nobody will use it, business continues as usual using a fork before that and he becomes irrelevant</i></text></item><item><author>0xFEED</author><text>There&#x27;s a number of things in that which aren&#x27;t totally correct.<p>&gt; <i>No, seriously, the decentralized nobody-needs-to-trust-anybody payments network </i>was shut down by an IRC channel&#x27;s consensus* for 8 hrs.*<p>It wasn&#x27;t &quot;shut down&quot; in any sense of the word, the network kept working (in duplicate, no less). It was the decision of two pool owners with extraordinary hashrates to sacrifice their chain (which was actually the &quot;correct&quot; one as far as intentions go), rather than the core developers.

Many more than, say, graduates in accounting or business administration from Manchester University, although a few might make it. Hell, I know a Harvard philosophy major who co-authored a very useful Haskell library.<p>My conclusions from anecdotal evidence:<p>- these universities, regardless of degree, encourage very
hard, focused work, and teach and encourage critical thinking; both critical thinking and hard focused work are useful in all jobs;<p>- people overestimate the &quot;technical&quot; portion of most jobs, and how easily it can be taught (a law conversion course takes a mere few months in the UK, and banks routinely train thousands of fresh unqualified graduates every year);<p>- people overestimate the marketability of skills taught in most &quot;useful&quot; degrees especially outside its area of specialisation (e.g. is a medical major more qualified a strategy consultant than a philosophy major?);<p>- you gain access to a vast alumni network and its reputation (which includes world leaders, the CEO of the companies you apply to, etc.);<p>- the selective nature of admissions sends the market a signal about your &quot;intrinsic&quot; quality.<p>(edited to be more readable on mobile)<p>Obviously, if you want to become a specialist and you are sure of it, it is a better idea to study that field in the best place you gain admission to.

There is no grand set of rights attached to all persons. There are an infinite different types of persons, entities to which some rights are attached but never all. We in the west normally understand &quot;persons&quot; as in flesh-and-blood physical people but even then what rights a person has depends on all sorts of things, from the location of their birth, to their age, sex, mental capacity, education or wealth. And yes, race can still alter a person&#x27;s rights under the law. What matters is not the &quot;person&quot; label but what rights this court is willing to recognize at attach to this new type of person.</text></comment> |

With the web BT functionality I can now put a simple interface somewhere on the web, open it on my device and control the ESP (I am not a web dev either, but simple JS toy stuff is easy enough).<p>Of course this might require swapping the ESP8266 for an ESP32 if BLE is strictly necessary (the former doesn&#x27;t support BLE, afaict).</text></comment> |

The rolling is perhaps made more obvious with my use of a graticule. For this reason, I’d be interested in optionally restricting to two degrees of freedom when dragging on the globe, and the third angle could be modified when dragging outside the globe only. So the point being dragged on the globe could still remain under the cursor where possible using this approach.<p>Interestingly, Google Earth uses the same approach as I do, though perhaps it seems less obvious without a graticule.</text></comment> |

This is something I&#x27;ve wondered myself for a long time. This same idea of a electric motor on the wheels powered by the APU(auxiliar small turbine for electricity and air presure, is the loud noise you hear when boarding the plane), is what some other pilots and myself have talked about for a long time.
Just taking in to account that it makes you autonomous when pushing back and taxing, the long times you spend waiting for take of at the runway, it makes a lot of sense for this kind of planes that spend a lot of the daily time taxing on congested airports.
I don&#x27;t know exactly the reason why it hasn&#x27;t been done before, I don&#x27;t think is a weight or technology reason. It surely has seated on a TODO list for a long time, just take into account that in aviation we are way behind in aplication of the latest technology. For example we are still using single chanel radio for comunications with control( this is terribly frustrating and ineficient, it&#x27;s pretty common to have comunication jams due to excess of traffics on the same frequency).
Airplane computers even in new models are still 90s models (very slow but i suppose that stability is worth the boredom). There are a lot of other vintage technologies in aviation, after all every single release to production must be tested and approved by the FAA and EASA. It&#x27;s the same for all major changes in systems and procedures. That makes all changes and improvements very slow and expensive.</text></comment> | <story><title>Paris Air Show’s Slowest Plane Could Have Biggest Impact</title><url>http://www.wired.com/autopia/2013/06/electric-taxiing-airlines/?cid=co9091394</url></story><parent_chain><item><author>kevincennis</author><text>Does anyone have enough knowledge of commercial aviation to explain why this hasn&#x27;t been done before?

I love JavaScript, but if device reusability is a serious concern then JavaScript is the elephant in the room, not this topic. Is it available? What version is supported? What quirks does the engine have? To be fair... it was posted in 2013 :D.<p>The only working alternative (editing if I stand corrected!) using buttons is to make them form buttons. Now otherwise intuitive behaviors (e.g. forward&#x2F;back, refresh) are laden with &quot;you&#x27;re about to resend data!&quot; warnings that completely break the flow.<p>To me, it makes perfect sense why this trend evolved. Most people agree with the underlying premise about user expectation on button vs link. Dressing links up as button is a direct response to that. I understand the technical arguments, but users care what it looks like and how it behaves, not how you implemented it.<p>Edits:<p>- Yes, you can use &lt;form method=&quot;get&quot;...&gt; without scary browser warnings. It just gets a but ugly if you have lots of buttons, as each needs its own form wrapper.<p>- 303 redirects to POST request are a handy pattern to be aware of no matter what :)</text></comment> | <story><title>Links are not buttons (2013)</title><url>https://karlgroves.com/2013/05/14/links-are-not-buttons-neither-are-divs-and-spans/</url></story><parent_chain></parent_chain><comment><author>superkuh</author><text>Everything is a button now that javascript applications have replaced HTML documents.

Understanding why things are discardable and pageable is interesting though.<p>Memory is pageable because live memory is precious. Your multi-tasking OS that supports paging can dynamically load and unload pages of memory to a backing store, say, disk. This means that if the sum of the memory being used by all tasks is greater than the physical memory available on your computer, your computer can still work.<p>Ah, but let&#x27;s consider a few facts. Data is stored in memory, but so is code. Can all the code in your system be paged to disk? There is some code in your kernel called the page fault handler. This code is responsible for identifying when the region of memory being accessed is not present, and can talk to the backing store to bring that memory back in. What happens if the page fault handler is, itself, paged out? What happens when the page fault handler needs to run?<p>So, now some code needs to be pinned into memory. It can not be paged out, or the system might stop working. Transitively, this property affects other pieces of code on the system following control and data dependencies between that code and the page fault handler. This can include device drivers that third parties write.<p>Some kernels say, all kernel memory is nonpageable, deal with it. Not Windows. In an attempt to make more memory available, it allows device drivers to mark code and data in the driver as both INIT and PAGEABLE. There are two contracts that you, the driver author, must live under when you do this. You must agree not to access anything in INIT after your DriverEntry (main) has returned, and, you must not attempt to run code in a PAGEABLE segment when the system cannot take a page fault. Many kernel mode components can easily fit code into these two contracts, so some good citizens do this.</text></comment> | <story><title>W^X policy violation affects Windows drivers compiled in VS 2013 and previous</title><url>https://codeinsecurity.wordpress.com/2015/09/03/wx-policy-violation-affecting-all-windows-drivers-compiled-in-visual-studio-2013-and-previous/</url></story><parent_chain></parent_chain><comment><author>0x0</author><text>From the reddit netsec discussion, it seems like this is a mildly interesting compiler quirk with no obvious real-life consequence, as the steps required for exploitation could be better (and with less effort) applied to directly attack kernel data structures instead...?<p><a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;netsec&#x2F;comments&#x2F;3jlipz&#x2F;wx_policy_violation_affecting_all_windows_drivers&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;netsec&#x2F;comments&#x2F;3jlipz&#x2F;wx_policy_vi...</a></text></comment> |

If yes, then it could query anything. Whether or not you&#x27;d like the experience is another thing.<p>Queries are programs. Querying data from a fixed schema, is easy. Hell, you could make an &quot;universal query language&quot; by just concatenating together this dasel, with SQL and Cypher, so you&#x27;d use the relevant facet when querying a specific data source. The real problem starts when your query structure isn&#x27;t fixed - where what data you need depends on what the data says. When you&#x27;re dealing with indirection. Once you start doing joins or conditionals or `foo[bar[&#x27;baz&#x27;]] if bar.hasProperty(&#x27;baz&#x27;) else 42` kind of indirection, you quickly land in the Turing tarpit[0] - whatever your query language is, some shapes of data will be super painful for it to deal with. Painful, but still possible.<p>--<p>[0] - <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Turing_tarpit" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Turing_tarpit</a></text></comment> |

Or if the app only needs a simple HTML UI that is OK.<p>The main problems I have encountered are:
- good performance is very hard to achieve
- making it reliable is difficult
- HTML5 data input is hard if you want to do anything more than the standard controls (e.g. a searchable combo like searching for a contact, e.g. a typable time entry field that defaults to a numeric keyboard that you can also type a colon into).
- pinch-zoom should be disabled (many many nasty bugs in iOS, Android, and IE10. Especially if also trying to use fixed position).
- position:fixed is broken (e.g. on iOS, when an input gets focus and the input is scrolled to screen centre the fixed div is not placed properly. Android and IE10 have other problems).

A page should automagically adjust so that it's optimal for a 27" monitor, a 2" mobile display, or anything in between. It's a great idea in theory, but I've yet to see it executed well in practice. I guess it's exceedingly difficult to design an effective UI that can automatically and seamlessly scale between a large-format screen and a small-format screen.</text></comment> | <story><title>Why LinkedIn dumped HTML5 and went native for its mobile apps</title><url>http://venturebeat.com/2013/04/17/linkedin-mobile-web-breakup/#ygWxXrYeFLq8hzfF.99</url></story><parent_chain><item><author>gbog</author><text> Why on earth would you disable pinch zoom on mobile web? It is the most useful feature, it allows the reader to adjust the amount and size of text displayed. I use it all the time and despise those web apps blocking it.<p>Html is elastic by nature, and html 5 will win over native apps because it is elastic.</text></item><item><author>robocat</author><text>HTML5 stinks on Android (due to bugs and fragmentation) and HTML5 stinks on Win8 tablets (due to IE10 bugs, implementation differences, also supporting mouse and touch together is hard to get right due to event models). So it regularly doesn't make any sense to try and build a cross platform HTML5 solution.<p>If you are producing a content app or business app, you might get away with it... Or if the app only needs a simple HTML UI that is OK.<p>The main problems I have encountered are:
- good performance is very hard to achieve
- making it reliable is difficult
- HTML5 data input is hard if you want to do anything more than the standard controls (e.g. a searchable combo like searching for a contact, e.g. a typable time entry field that defaults to a numeric keyboard that you can also type a colon into).
- pinch-zoom should be disabled (many many nasty bugs in iOS, Android, and IE10. Especially if also trying to use fixed position).
- position:fixed is broken (e.g. on iOS, when an input gets focus and the input is scrolled to screen centre the fixed div is not placed properly. Android and IE10 have other problems).
- all scrolling solutions have downsides.</text></item></parent_chain><comment><author>miniatureape</author><text>In some browsers, removing the ability to zoom removes the 300ms delay that the click event has before it fires.<p>You can use 'touchend,' but in certain cases this causes another set of bugs because the click event follows anyway.<p>To fix this in a cross-browser way, you need to write some extra logic. There are several implementations floating around of various quality.</text></comment> |

And I don&#x27;t think raising interest rates is going to spur housing starts or investment in production capabilities.</text></item></parent_chain><comment><author>colinmhayes</author><text>Rising housing prices are caused by the post 08 slowdown in building. The Bay Area alone is 1 million units short . We need to deregulate the housing market. Only 2% of units nationwide are owned by large scale investors. That number is going up, but for now it’s not a real problem.</text></comment> |

You&#x27;re also comparing papers like the New York Sun and other tabloids, while this article is talking about respectable papers such as the New York Times.<p>I&#x27;ll quote the relevant part of the article:<p>&gt; The real story in this mess is not the threat that algorithms pose to Amazon shoppers, but the threat that algorithms pose to journalism. By forcing reporters to optimize every story for clicks, not giving them time to check or contextualize their reporting, and requiring them to race to publish follow-on articles on every topic, the clickbait economics of online media encourage carelessness and drama. This is particularly true for technical topics outside the reporter’s area of expertise.<p>&gt; And reporters have no choice but to chase clicks. Because Google and Facebook have a duopoly on online advertising, the only measure of success in publishing is whether a story goes viral on social media. Authors are evaluated by how individual stories perform online, and face constant pressure to make them more arresting.</text></comment> | <story><title>Anatomy of a Moral Panic</title><url>http://idlewords.com/2017/09/anatomy_of_a_moral_panic.htm</url></story><parent_chain><item><author>vonnik</author><text>Ironically, the premise of this critique of journalism is as false as the Amazon story it cites.

It’s true that this made the question a bit of a moving target for me (and therefore harder to address coherently), but I don’t a-priori assume that the incident was rooted in sexism. Maybe I’m too naive, but I simply gave him the benefit of doubt that he was so excited by the newly-learned idea of the duality that he couldn’t resist, and that the same might have occurred had the panelist been a male instead of me.

There&#x27;s something like 13 different mechanisms that co-operate in sound localization.<p>However, the bulk of it was known quite a bit before 1985, and had nothing to do with the &quot;spatialize me&quot; button on a specific car stereo.<p>There&#x27;s no simple way to add a delay to some speakers unless you&#x27;re working in the digital domain. In analog you have two basic choices. With passive components, you build a ladder filter, which is as the name suggests, just a long chain of low pass or all pass filters. Each &quot;rung&quot; only adds group delay on the scale of a couple usec, so these get very big and expensive fast. They also suffer from accumulated imprecision issues. With active components you can create a feedback loop through an op amp. This is how guitar delay pedals work, but the more delay you have the more distortion you introduce.<p>Technically there&#x27;s a 3rd way: extremely long wires, but that&#x27;s basically never practical.<p>Thankfully these days everything starts out in the digital domain, so you just need a controllable fifo before the DAC. Entry level home theater receivers have had this since circa 2000.</text></comment> | <story><title>The human ear detects half a millisecond delay in sound</title><url>https://www.aalto.fi/en/news/the-human-ear-detects-half-a-millisecond-delay-in-sound</url></story><parent_chain><item><author>function_seven</author><text>My dad bought an Isuzu Impulse in 1985.

It would be interesting to hear about how this sort of machine could affect companies like McDonalds and whether or not it's <i>the future</i> or just a cute idea that won't scale?<p>I have the feeling that, if this sort of idea was as value as the article implies, McDonalds (or Burger King, or any other big chain) would have put serious money into developing this sort of thing and it would already be everywhere.<p>(I wish there was a website or publication that took businesses and profiled how they work, the challenges they face and the costs associated with parts of the business consumers might not understand, so these sort of questions were easy to answer. I would love to read how McDonalds works (as a business))</text></comment> | <story><title>This robot serves up 340 hamburgers per hour</title><url>http://singularityhub.com/2013/01/22/robot-serves-up-340-hamburgers-per-hour/</url></story><parent_chain></parent_chain><comment><author>anandkulkarni</author><text>When I met the Momentum Machine guys here in San Francisco, I was shocked that they were planning to open a restaurant chain instead of licensing the technology out to existing players. Opening restaurants? Making food? Very un-startupy, right?<p>But it turns out that if anyone can do it, these guys can. The brick-and-mortar restaurant business is massive, bigger than many technology sectors, and prime for disruption with new food and models: there's a $184 billion global fast food market, a $2.1 trillion global market, and just about everybody needs to eat.<p>This has the potential elements of greatness: serious, hardcore mechanical engineers as founders, with a background in the restaurant industry. More power to John and Alex -- can't wait to try my first one.</text></comment> |
