In case of Earth, Wikipedia describes [1] it as being "[..] generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core". This makes Earth a geodynamo [2]. (The aforementioned Wikipedia page is actually really long and detailed, a lot more than I would have thought)

Yes indeed, this is what we do :) There is an opaque Mask type for which operations such as CountTrue, AllFalse etc are provided. If you really want the one or other representation, VecFromMask and BitsFromMask/StoreMaskBits convert as required. The former is a no-op on AVX2.

As to the AVX2 comparison, for ICL I think we can do two of those per cycle, so no more than the throughput of an AVX-512 mask comparison. The question is what we do with it afterwards - for VQSort (one of the few applications where comparisons are really the bottleneck?) we are much happier to have the packed bits, because that can feed into vpcompress or a LUT implementing that.
Muggy city keeps cool with minimal AC
The only way to keep standards high is to cease using degrees solely as class indicators and stop requiring a bachelor's degree for the overwhelming majority of white collar jobs (that we all know don't need the specific knowledge from the degree or else the required degree would be more specific, and that we also know the degree doesn't indicate work ethic necessarily, go look at the people working much harder precisely because they don't have a degree, if anything the degree serves as a license to slack off like the upper class so).

Otherwise the potential downside of not graduating with at least a bachelor's degree is so devastating that the population (who don't want to be perpetually responsible for their adult children that have been made unemployable in any decent capacity for no reason other than to make certain email job people feel important) will accept nothing less than a pass rate approaching ever closer to 100%.

If you want to make education rigorous, you have to address that problem and then also try to address the K-12 education system that faces a similar but more extreme version of the same issue (because not being able to properly read and write are genuinely bad indicators for the majority of white collar jobs, and failing to graduate high school tends to indicate fundamental issues in that respect moreso than failing to graduate with a bachelor's, which usually just indicates immaturity / lack of money / boredom / a million other things that don't imply missing fundamental skills).
Cool thing.

How do you handle the interaction between 2 pieces being moved at the same time ? Can I dodge a capture by picking up a piece ? Say 2 rooks are facing each other, how do you handle a mutual capture attempt ?

I have solved this problem, but still in a turn based setting :

* Both player choose their move, and moves are resolved simultaneously

* A piece cannot be moved 2 turns in a row (discrete cooldown time)

* When 2 pieces land at the same place, they are both considered captured.

* If they move in straight lines, in opposite direction, they are also both captured.

* NO CAPTURE for pieces crossing each other path / knights can exchange their positions.

* No pat. A player can skip his turn.

* the goal is to capture the oposite king obviosuly, not to checkmake it.

With a low blitz time, it solves the same fundamental problem as RT chess, but it can only be played online.

From a few test game, it looks like basic chess structure is preserved. But then there is the question of finding the Nash equilibirum of the game ! 2by2-simultaneous-move-chess with both rook and king leads to some sort of rock-paper-scissor.
That just pushes the question off a step; a chair fit for sitting isn't fit for sleeping, etc. Fitness assumes a purpose.

I think it won't be far-fetched to say the current generation of children possibly has the lowest impression of their elders as compared to all previous generations in human history.

Not that you can blame them, honestly, looking at the state of the world despite all wisdom and knowledge being more accessible to everyone than it has ever been...
“I do not care how dumb the bureaucrats are, as long as I get the result of you spending thousands of hours designing something almost magical for free without paying you”
I haven't seen any data that backs that up based on general principals. Most of the cost is in artificially-imposed operational requirements - however well founded.

Also, remember that nuclear, unlike solar, has a lot of room for improvement still, both in how it's done, and how it's regulated. Solar has already been tremendously optimized, while nuclear has not.

The cost argument seems to be advances by the same people who impose or support the additional operational requirements, and who also just have a philosophical aversion to nuclear power.

There are hundreds of nuclear power plants already in operation, many decades old. There have been only a very small number of minor accidents (3 come to mind: Chernobyl, Three mile island and Fukushima), in which only a few dozen people were killed. Nuclear, even using old technology, has proven to be far safer and better for the environment than any scalable alternative, including solar. New designs are even safer.

Sure, but not all degrees are equal. Institutions have reputations based on how smart / effective their graduates tend to be. So by making it harder for the careless ones to graduate, a university can enhance the value of the degree for those that do. Even with the transactional attitude, it would behoove students to want to be pushed.

Exactly my point (I couldn't tell if you were agreeing or disagreeing). I pulled the "1fps 100ms" number as target that a user might tolerate for a typical embedded display. And since as I said modern higher-end microcontrollers are much more powerful that dos-era CPUs (which could run games much faster), the unspoken conclusion I was trying to convince the previous commenter of is that a GPU (beyond maybe a specialized blitter-like pipeline) is unnecessary for the demands of typical embedded application displays. I was also going to give the example that the GUIs of early versions of Windows were software-rendered too.

Out of curiosity I'm looking at the most recent demo video LVGL posted, which benchmarked an ESP32-S2, and it's getting between 50ms-100ms for various tests like rotating multiple bitmaps and such.[1] So seems like the "100ms" number I pulled was quite apprirate for what LVGL can do on on a popular modern microcontroller.

(Also note for any readers: when I typed "1fps", that wasn't a typo for "10 fps". An embedded application would be wanting to do something else for that ~90% remaining CPU time each second that is not spent software-rendering the GUI.)

I'll believe destroying stacktrace information is a valid complaint when people start complaining that for loops destroy the entire history of previous values the loop variables have had. Tail recursion is equivalent to looping. People should stop complaining when it gives them the same information as looping.
Ugh yeah that's why you tell them it's been put out.
Devices are smaller and portable batteries are treated roughly. Also, many devices have batteries with custom-ish shapes that may be better or worse than standardized designs that were popular before devices get thinner.

The other thing is that consumers won’t be aware of risks for semi-disposable batteries. I found out a few days ago that a high capacity Anker battery that I own was recalled last year. Would such a thing even happen for a random battery sold at CVS?

I was in a leadership role for an org with about 95k laptops. We had, on average 4-6 significant battery incidents with an ignition per year. Anywhere from 30-250 reported battery swelling events annually. It’s enough that we provided kits for safe storage of at risk batteries to every field office.

Now that’s a pretty low risk of an incident, but in an airline environment the impact of that risk is very high.
Sure - to be clear, I am not suggesting banning technology itself. Computers and the internet were also a boon of joy and discovery for me. I self-started programming in TI-basic back in middle school because "computer science" classes that covered anything beyond typing and "here's how to use to a web browser, here's how to use a text editor" skills weren't available until high school for me. I have vivid and fond memories of learning visual basic and making my own GUI apps after this, before eventually starting to learn javascript, python, and "real" programming languages like C.

None of this exploration ever required or involved Facebook or other social media platform or highly immersive video game, save YouTube.

And to be clear, I'm no proponent of the state simply passing universal bans, or infringing upon privacy of adults with facial recognition requirements for using social media, this is a responsibility of parents, many of whom I fear themselves haven't been adequately warned about how addicting these platforms are.

I don't think DARE-style assemblies for both students and parents would be the worst idea to warn both groups about the risks of these platforms, provided they were done honestly, rather than being filled with hyperbole. It doesn't infringe upon anyone's rights, and wouldn't really "cost" anything, but would help educate those who might lack the awareness on the subject.
And that is why we can’t have nice things, apparently.

Solve the waste problem and you solve nuclear. Waste is still the giant elephant in the room and a lot of people have a fifth grade solution to the problem (we will bury it under ground! We will fly it to the sun! We will resuse it until it is no longer radioactive!)

I used to have a neighbor who worked for the DOE, all of the viable solutions are blocked by people who don’t want it in their backyard. Can’t really move forward until that is solved..
Yep, including draining the store buffer.

We've gotten our ThreadPool barrier+wait to use only acq/rel, but not yet the work stealing. Does anyone have experience with that already?
Best Linux distro in 2025 for non-experts
This is about finding a good linux distro for my parents to use. Apparently, Windows now requires an outlook account in order to log into your computer. Well - his outlook account has been hacked. (In fact, it's the second time he's had a Microsoft account be hacked. He's pretty savvy about scams and phishing, but we can't figure how how this keeps happening.) Anyway, understandably, he's pretty freaked out about what they might have access to on his computer and will probably end up just reformatting it.

He's open to switching to linux, but I've been out of the game for a while and not sure what to recommend. In olden times, Ubuntu was my go to - is that still a reasonable default or is there a new game in town?

They primarily use the internet and I guess they might need to print sometimes (which I'm assuming is going to be a hassle no matter which distro we pick).

Until I hear a vote of no confidence from Paul for YC’s current leadership, I have no interest in anything he has to say. After all, Elon Musk — the guy cheerfully and illegally dismantling the federal government, who called my friends “parasites” for taking benefits and apparently wants to see witnesses against the president executed, who enthusiastically supports far-right populist parties like the AfD and makes suspiciously Nazi-looking salutes on stage — is still invited to YC’s AI Startup School. Garry Tan, it seems, has no problem with any of this. I’m sure he relishes a new world order where he sits on the board of Yarvin’s fever dream government.

Want to do something good, Paul? Do everything in your power to stem the bleed of encroaching fascism and neo-reactionaryism. Put your reputation and wallet on the line. Be a leader. Otherwise, you’re just posting platitudes while one of the world’s great democracies dies an agonizing death by the hands of your peers.
A bad question, as it has been doing that literally (rotationally) since before life started. This power is busy generating the magnetosphere. We would not be enjoying our nice oxygen atmosphere and would be as dead as Mars if Earth's rotation wasn't also powering a dynamo.

Functions are just containers of calculations (the whole “code is data”).

I don’t know why lists as values in a container would be confusing. Lots of very popular languages literally have box types which may not be exactly the same, but show that expecting containers to potentially commission complex data isn’t unusual.

> Karl Popper pointed out that the free speech must defend itself.

Yes, that's in fact a very old idea - that the "soap box" must defend itself with the "ballot box", and the ballot box with the "cartridge box". But what's happening now is a lot worse: free speech is being destroyed for the sake of not "causing offense". Which amounts to giving express legitimacy to intolerance, and saying that it must always win over tolerance.
It's only about one shelf in a standard bookcase.
Did he mention speech?

I think you refer to the quotes about the paradoxes of freedom and tolerance.
You're kind of making his point - the second and third paragraphs are explicitly about the fact that he is not an Ivy League professor. Be the change you want to see in the world by doing the reading first.
I did mean sum types, variants, etc. It's not really clear what I meant by representing the data but I'm referring to type inference. SML can't solve the problem, and Lisp doesn't have it.

I also dailied it on XFCE. The UI was very utilitarian and purposeful. I suppose aesthetically it is unimpressive and not streamlined, but it serves the purpose of being a good interface to do a task.

Same as you say, people have asked me a lot about it and even asked me if I could set it up for them. The theme is evangelizing Linux a little bit, and that is interesting. In the right hands, these UI principles could convert many people to some product.

Noooo, really?

It all depends on what you want to do. For things that are already in files like all that data that DeepSeek and other models train on and for which DS open sourced their own distributed file system, it makes sense to go with a distributed file system.

For OLTP you need a database with appropriate isolation levels.

I know someone will build a distributed file system on top of FoundationDB if they haven’t yet.
I've no clue why people have downvoted this; you're right as rain. A phone is nothing short of a digital slot machine and shouldn't be put in front of adults or children. These algorithms are designed for profit, not humanity. They have far greater control over us than they should.

> I don't think DARE-style assemblies for both students and parents would be the worst idea to warn both groups about the risks of these platforms, provided they were done honestly, rather than being filled with hyperbole.

Yeah that's fair. Probably can't hurt anything with that. But it's hard to get the actual danger across.

> None of this exploration ever required or involved Facebook or other social media platform or highly immersive video game, save YouTube.

That's why I am gunning to limit these kind of platforms, specifically.

> It doesn't infringe upon anyone's rights, and wouldn't really "cost" anything,

Well it depends. If these assemblies worked, they would "cost" the platforms potential engagement and potential revenue. Which is kind of a pointless distinction, I just thought it's interesting
Aren't we just saying that matter is complex enough to form an input to a model of the world and self which results in a really complex feedback loop where organisms which adjusted actions to increasingly complex projected model state had more descendants?

The self is just the only part of the model directly wired to our neurons and self awareness is just correct labeling.

In that context will is certainly a function of a how much a things internal model of self encoding the idea that its actions are moreso based on its own model than the tgings its model is built with and ability to make this distinction right or wrong and free will is basically meaningless.

Its certainly not a magical out for determinism all the qualities that we imbue with such meaning are as based on the same principals as anything else.
> “China had a plan when they let Tesla have a fully owned factory. They wanted the technology and the knowledge and experience. With that came a risk China would take that technology and build better stuff,” said shareholder Ross Gerber, CEO of Gerber Kawasaki Wealth and Investment Management. “That’s exactly what they’re doing. Now they’ve got really competitive vehicles, really competitive technology and the vehicles are cheaper.”

They seem to allege that BYD somehow mushroomed on the Tesla secret sauce. But really? It seems to surpass it on all angles.

I'm sure they wouldn't be beyond IP grabbing, but let's give credit where it is due. BYD cars just seem better than Teslas, regardless of subsidies, labour costs and price comparisons.

Someone should correct me if I am wrong, but AFAIK - PG stands behind current shift in USA’s status quo. That is, support of MAGA, Trump, DOGE, techno takeover of USA, that vague idea of of converting USA into totalitarian corporate city states controlled by billionaire techno class.

Hence - people are now much more critical of him.
Supposedly, according to their financial reports, Tesla has $37 billion in cash and equivalents.

That they haven't got the Tesla semi into series production, that they don't have a new roadster, nor do they have a new lower cost car, nor do they have nearly enough 4680 cells to update all of their battery packs, nor do they have a plausible robotaxi vehicle and that two seat gullwing thing isn't it, you have to wonder why?

Not "Why are they somehow blocked from having these things?" but why haven't they even spent more money to try to get there? That's a bigger mystery than what happened to $1.4 billion or how to sell 6800 Teslas in two days in Canada.
