I agree about GPUs. Intel used to have a low-end CPU with a 128MB L4 cache that was shared with the iGPU. It turns out having that large cache improved a lot of regular software too. I'd rather see die space used for that than AVX512.

The only AVX512 instructions that actually seem essential imo are the VNNI extensions.

There are a lot of use cases for a neural network that is trained on the GPU but where inference is done on a bunch of CPUs because it's cheaper than buying/renting inference hardware.
That's fine, because the US government can't print Bitcoin and hand it to megachurches and wealthy corporations every time there's an economic downturn.
Software Development in a Nutshell
100%, this is also driving capital into the private equity markets (of which VC is a subset that is very relevant to Hacker News readers). Startup funding has remained exceptionally robust, especially for companies with traction at the later stages. All of that capital lost at sea, looking for a port in the storm.
It has a linuxy backend with a good gui frontend. And the hardware is usually very good. I just don't really like flapping about trying to get everything working well in linux.
> I'd argue that without modern IGBTs, it'd be impossible to make an electric car today.

Er, everybody switched to SiC MOSFETs, so... definitely not.

> The power-switch that controls "on" vs "off" needs to be incredibly efficient when you're shoving 200+ kW of energy through it!!

Even before SiC became economical, FETs were edging out IGBTs in most applications. The voltage drop across IGBTs is just too high.

In fact SiCs have worse on/off efficiency, but are still preferred because they can switch more quickly and in the end that makes them more efficient, overall.

> Its probably one of the most major sources of efficiency in the modern electric vehicle.

I would give that to the battery or the motors before the controller. Controller have been >97% efficient for ages and ages, but motors are another thing entirely and better computers, salient rotors and permanent magnets, and better characterization have led to bigger gains than the switching elements have seen.

Neither hold a candle to batteries though. The resistance of switches is <10 milliohms, and motor resistance isn't much higher. The resistance of a 400 volt, 250 Ah NiMH battery is around 180 milliohms. The same battery built with venerable NCR18650Bs (original model S) is 68 milliohms. That's a full 7x improvement, or an 86% reduction in loss, and by far the biggest inefficiency besides aerodynamics and rolling friction.
Man, I did not see that change... I read it a couple of times, too, to make sure it was the same.
I agree but for different reasons. There is no financial incentive to run a TOR node-- it's expensive and opens you to real legal risks. Therefore most nodes are run by universities and unknown actors-- in any case they are almost all funded by the state. If I was a nation state it would make my job much EASIER if I corralled all of the bad actors into a network that has a handful of defined exit points more or less under my control. The entire notion is absurd. I2P is actually more secure because it routes traffic dynamically rather than trusting a centralized "authority"

David Deutsch is the only person who has a theory of everything, not just for mechanics. He connects quantum theory (he wrote the first quantum algorithm), evolution (of genes and memes), and computation into the only true theory of everything. It's elegant, meaning the explanation of the theory is beautiful and highly structured. He presents it in The Fabric of Reality (1997) and has since been building it into constructor theory http://constructortheory.org/

The flu also also causes significant delirium in hospitalized patients:

https://onlinelibrary.wiley.com/doi/full/10.1111/irv.12177

Brain swelling caused by the flu is more dangerous than swelling caused by SARS, this research was done in 2013. We don't know if applies to SARV COV2, but it is a positive sign.

At this time the "discovery" that COVID-19 causes delirium in hospitalized patients should not cause anyone to panic, as it is a well known side effect of SARS like viruses.

Why it is being presented so sensationally I cannot say, it has been known for three months that patients with severe symptoms that originate in the nose (not chest) are in danger of a mild encephalopathy.

A typical clickbait title.

No, dolphins are not helping us hunt for aliens. Rather, researchers are putting forth the idea that dolphin intelligence might be a good model as they search for other intelligences in the universe.

As an aside, John Lilly is described as a neuroscientist who in 1961 was best known as trying to talk to dolphins (George C. Scott's character in Day of the Dolphin was based on him). He went on, however, to be equally well-known for his experimentation with LSD (which inspired a second Hollywood movie, Altered States). Lilly also developed the first sensory deprivation tank.

You would think that Lilly would appear on Wikipedia's listing of Caltech notable alumni, but he does not.

Linus somewhat waved away the idea of tradeoffs, which is fine, he was speaking in generalities.

Changing the law takes a fair amount of time, and it would unlikely be retroactive. Not to mention that if everyone is doing it (and it doesn't go against the Charter), good luck legislating against it.

Historically, predatory behaviour by media companies in Canada has been pretty badly received by both major parties, which is how we ended up with notice-and-notice, where the emails have a long intro about "this is just a notice and you don't have to do anything".

I don't encourage piracy, but it's probably the kind of thing that most people do occasionally, while also being 'good' paying consumers.

Agreed both being very impressed by Illich, but it not being workable. I dimly recall The Alphabetisation of the Popular Mind arguing that possibly you shouldn't teach language.

Eleos Technologies | Android Engineer | Remote (US only) | Full time |

Eleos Technologies is a growing 9-year-old company building communication software for truck drivers and field workers.

We’re helping a diverse mix of customers—from mom and pop operations to household names—improve how they communicate with their employees by tackling information overload, reducing phone calls, and eliminating obsolete technologies.

Our app is used by thousands of big-rig and small truck drivers, day and night, every day, and we've been on a sustainable growth curve for long enough that we're ready to grow our Android team from one to two!

The app does some unique things, including assisting drivers to plan their trips, find stopovers, manage their electronic duty log, and more—there's a lot more than just CRUD and chat features to go around.

As a remote team, we're super lucky to have some great folks who use the ability to work from home to spend more time with their kids, help volunteer at a school, or otherwise be more fulfilled than they would be working from an office. You could join us!

If that sounds fun and rewarding to you, the full description and info about applying are over here: https://jobs.lever.co/eleostech/94ff56e4-9ca3-4fdd-b769-9238...
Also, Intel almost never provides the frequency throttling details for AVX-512 heavy workloads, which is called AVX base frequency.

You can only see the performance values for yourself, or believe the SPEC benchmarks.

If you're working in an HPC center, you may ask your fellow centers and get off-the-record answers, sometimes.
The belief is that they will follow the same path for both ridesharing and trucking. If and when Autopilot is able to handle fully autonomous driving, Tesla will turn on that ability for owners to rent out their vehicle with Tesla taking a cut. Once that is successful, Tesla would then start to build its own internal fleet of autonomous vehicles to rent out and take all the revenue. This Tesla owned fleet would be the second stage because the vehicles themselves have a huge upfront costs. There is no point in incurring that upfront cost until the system has proven to be profitable among existing Tesla owners.
«No, bitcoin isn't going to become a mainstream kind of money. It's too awkward for most people.»

This strikes me as something written by someone who is fundamentally not a problem solver. It's like someone seeing the first cars in the late 19th and early 20th century: awkward, unreliable, etc, and thinking "clearly, cars are NEVER going to become mainstream".

Really? You can't think of any way the technology and tools could improve to make using Bitcoin less awkward?

> the main immoral thing about theft is that it deprives someone of what they used to have

You should have just stopped there. That "or takes the place of a sale" rider is a very recent invention. You know what else takes the place of a sale? Spending your time doing anything else and ignoring the fact that the work even exists. If I could have paid to listen to a song from artist A and instead I listen to a song from artist B (free or paid, but we'll assume it was with permission either way) then that "takes the place of a sale" for artist A, but there's absolutely nothing immoral about choosing to listen to artist B's song instead. Or reading a book, or sleeping, or whatever. You could even write your own songs and give them away for free, directly competing with artist A and taking the place of many sales, and there still wouldn't be anything immoral about that. Artist A was never guaranteed sales, so they haven't lost anything simply by not making a sale. They still have their copy of the work, so they have not in fact been deprived of anything.

Complaints about piracy always read to me as: "You aren't complying with this monopoly which was promised to us in a rather one-sided deal with a third party (government) which (unilaterally) claims to represent you. If you don't shape up—or even if you do—we intend to sue you for everything you own in courts run by our beneficiaries and otherwise do whatever we can to ruin your life, just on general principles and not because we suffered any actual damages." And yet they have the audacity to pretend to claim the moral high ground…
Yes, that would be me, and half if not most of my colleagues.
Association between active commuting and mortality
> I've been a bit short with you because you've written long speculative comments without making any attempt to look up the numbers yourself. That's something to be embarrassed about.

That's an assumption on your part, one that is both incorrect and unfortunate. (as far as theoretical physics is concerned.)

Embarrassment, however, is largely irrelevant when trying to understand anything in a systematic way.

> and it offends me to see you play-acting as a critic of science without even understanding the lay of the land.

Offendedness. Well, we simply have different experiences and perspectives within academia. We see the land differently. If that's your threshold for offence then life must be difficult indeed. I don't envy your position. If it will somewhat assuage your being offended I should tell you that, as a mathematician, I champion science above any other human activity. But who I am and what I do should be irrelevant when testing hypotheses.
>One heuristic I use for evaluating technical material is orthography: if you spell or capitalize or spell something improperly, it's likely you'll get a lot else wrong too.

And while the program env is lowercase, the environment is commonly referred to as ENV in technical literature, APIs and so on. If you didn't know that, it's likely you are getting a lot else wrong too...

Plus, the "heuristic" is bogus anyway. Though it might be fine for evaluating candidates for secretarial roles though...
I was unschooled as well, in the 1980s, and I'm considering the idea of a modern interpretation of this for my future son.

If you can afford a garbage collector, then you can also just use something like Haskell or OCaml or Python, which also gets you memory safety. No need to think about lifetimes or different types of smart pointers. Not saying that it’s a lot of mental overhead, but it’s definitely a trade-off.

The whole OSS licensing field is a true minefield. IMHO, the Creative Commons folks (CC) have done a much better job at creating a series of clearly defined licenses. With CC, you can quickly determine the freedoms and responsibilities conferred by each license.

Meanwhile, in OSS, you have to research the fine distinctions between BSD-2 clause, BSD 3-clause, MIT, etc. Or Apache vs. Eclipse, etc. Even fundamental distinctions such as between OSS and Free Software (GNU-style) are regularly misunderstood, as in this article.

I'd like to see the OSI convene the organizations that have issued the various licenses and get them to agree on a new OSS licensing scheme modeled after the system used by the Creative Commons.

I think everyone would benefit from that level of clarity.

The reason we have low-quality public schools is because education is criminally underfunded and poorly handled, especially in poor areas because of property tax funding.

I don't fully support removing magnet schools, but you can bet that if rich families had to send their kids to the same schools as the poor kids, they'd be lobbying all day for better funding. Apportioning funding per-head from state taxes rather than property taxes would be a good first step.

Totally, and French intellectuals don't usually go over well with the average reader of HN. But, if anyone finds the discussion in this comment section resonates strongly with them, just reading about Foucault's ideas would be a good place to start. Why limit ourselves to school. :) This is fertile ground for thought and I'm glad to see discussion here.

> I wish Foucault had provided a more thorough treatment of schooling, though

Agreed. I think most schools were just broadly more authoritarian when he was writing. There's certainly more room to discuss the ways in which schooling has changed as we've shifted from the factory to service and knowledge economies.
There's many reasons why he isn't considered a good architect:

- Notoriously bad detailing (see the lawsuit associated with the Ray and Maria Stata Center at MIT). Precise detailing is a reflection of an architect's craftmanship, and something a lot of architects take a lot of pride in.

- No theoretical or functional underpinning to his work, it's literally just a large sculpture. Architects who do incorporate sculptural form (Zaha Hadid, Rem Koolhaas, Alvaro Alto, Oscar Niemeyer, Preston Scott Cohen etc) are a lot more rigorous about how and why they deploy this strategy.

- A related criticism: little to no translation of his sculptural forms to the interior. If you cut a section through his building you'll see that the building contains a lot of empty, useless space at the corners, and then a lot of typical boxy rooms inside. Again look at someone like Koolhaas, Cohen or Zaha to see how efficiently and effectively they integrate their geometric experimentation.

- The most impressive part of his projects: the structural calculations, construction and implementation of his work was achieved by others at Gehry Technologies, a technology spin-off that he's basically outsourced all the difficult/interesting parts of his project to. If you look at architects who do structurally experimental work (Santiago Calatrava, Antoni Gaudi), they're actually integrating their analytical work with the design.

Gehry himself has said he's more of an artist then an architect. I will say though, that one of my favorite architects (Rafael Moneo) once wrote a pretty good defense of Gehry's work in his book 'Theoretical Anxiety and Design Strategies in the Work of Eight Contemporary Architects', albeit focusing mainly on his use of material.

ETA: Oh god. Reading the hacker news crowd confidently opine about architecture is excruciating. There just seems to be a huge gap between what people think architects do, and what the discipline actually does.
> If five years from now everyone in the world has become a bitcoin user, that could only be because something very very bad has happened to the regular monetary system. Perhaps hostile aliens have enslaved us and are using the payments system to control what we can buy, sort of like Margaret Atwood's Compucounts in her dystopic Handmaid's Tale. And so bitcoin has gone mainstream, but only because we have all been forced to become under-the-table bitcoin users in order to buy stuff we need.

I'm not sure the author is paying attention to what really is happening to money around the world.

- Local currencies are being weaponized in various ways from countries to individuals, including surveillance, sanctions, and civil asset forfeiture.

- Physical currency is being withdrawn incrementally around the world, forcing citizens into electronic payment networks with greater weaponization potential.

- The dollar's position as global reserve currency and asset have placed unprecedented stresses on the US financial/political system. there are only two options: default on the national debt(s) or devaluation. It's not going to be default. So, for as long as the global dollar short squeeze[1] rages, the Fed's balance sheet will expand, fuel devastating bubbles, and cause rational people to look for alternatives in the strangest places.

- Gold is increasingly becoming problematic if held abroad. Venezuela recently discovered that gold stored in UK vaults can be stolen by men in 3-piece suits. This makes the picture around gold as a settlement asset increasingly murky.

Bitcoin may or may not offer solutions here. But to brush off obvious problems with the world's financial system at this moment in time seems rather short-sighted.

I have the webcam on top of my desktop monitor, when I videoconference, I slide the whole monitor lower so that the camera is just above height of my eyes and I put the chat screen on the top of the screen, so the talker on the screen and the webcam are just a few cms / inches apart. I sit about an arm's length away from the webcam.

It's not perfect, but it's adjustable within 3 seconds and is very close to directly looking into the camera.
Reference counting doesn't solve all memory management problems. With closures you often end up with circular references.

And yes, in probably 99% of cases you can actually find a way out of a memory management problem in Rust if you think hard enough.

But my point is that quite often you don't want to think about memory management. Rust doesn't help here. Rust advertises that it solves memory management problems, but in reality that only holds up to a point. So use Rust for your OS or your low-level server, but don't think it is a panacea.

This is like a bingo chart of right-wing fearmongering rhetoric.

I don't know, maybe I am out of touch but almost all boomers I know are extremely well off, they started as scientists or other typical professional occupations and now own assets in the millions, basically housing in California and other areas. Prop 13 has helped them(their prop. taxes do not go up) as well as dirt cheap college costs when they went to college. Housing was rather cheap as well considering salaries, I remember my Dad looking at houses in Palo Alto in the mid 90's and they were in the 300's(they are now 3-4M). I feel like gen X and Millennials are really getting the short end of the stick when it comes to alot of essential life costs. Sure economists say inflation is not happening but I think the formula to look into inflation is incorrect as Housing/Medical/College has skyrocketed where a gallon of milk and bread has not jumped in cost.
