Mining.com, who would seem to be knowledgable about mining, disagree: https://www.mining.com/web/evs-vs-gas-vehicles-what-are-cars...

Do you have a source for your claim that cobalt/rare-earths are used in conventional cars to the same extent as electric?

And my point all up is that no new vehicles should be mined/built/purchased, at least while any old reasonably efficient one remains drivable. And that is what I have done. Pulling a bunch of lithium out of the earth isn't better than simply using what we already have made.

> Is it still a recommended practice on the US to rely on overcurrent protection to protect against current leakage? It's an horrible practice, as it requires several amperes of leakage before triggering.

Yes.

I don’t agree with it, personally — I think that there should be standard ground fault trip curves that are functions of circuit breaker rating such that they coordinate properly, and that they should be used at least on all circuits that extend outside of a building and really on most circuits, period. This would add costs, and it would detect and thus prevent a lot of dubious wiring practices and outright errors.

But you should still bond all your “ground wires” together so that even if these breakers fail to trip you have a degree of protection. (And breakers do fail.)

Under current NEC (the US code), when you supply a building with a feeder (i.e. from another building or similar structure), you must provide it with all the current carrying wires and separate ground, and you must ground it to the Earth.

In any case, if you live in a place where your utility supplies power above ground, and a utility pole or line is hit by lightning, its ground is most certainly solidly connected to your house. So you can’t really pretend that your house’s ground is connected only to the Earth near your house and that it won’t let lightning in.

Hmm, I wonder if you can take the ground wire running between two buildings and carefully insulate it and give it a wrap or three around a piece of steel to add some inductance and reduce lightning currents that might otherwise go through it. I’m not saying this is wise…
Most servers have something like an announcements channel. Muting everything but that is the equivalent of subscribing to an events / other big news mailing list for (Discord-centric) communities, these days. You'll only get notifications for that, and can still engage with muted channels on a pull basis whenever you want.

It’s in China. Lately it feels like the real question is not “can we deploy these technologies scalably” but rather: “can the West possibly catch up with China.” It’s thrilling that things are moving so fast in China, but simultaneously really worrying that we in the US and Europe are so far behind on the deployment of renewables and battery tech. It also feels like our financialized system deploys capital on a ridiculously short time horizon, while China has correctly realized that it can make uncontested long-term bets in these critical areas and destroy the competition.
In Twitter/X's case, I'm not sure how much is related to large cuts in headcount and how much is that Musk's behavior just cause a lot of people and companies to re-evaluate their relationship with Twitter.

I've got nearly 30-year-old optical drives that still work fine today. I can plug a 3.5" floppy drive into my Android phone and it still works. Sure, there's a chance in a decade or so SATA ports disappear, but USB adapters still work. Do you really think in 10-15 years it will be hard to find a device that still talks USB?

ZIP drives had a number of mechanical issues (click of death). That's probably the biggest reason why they're challenging to try and use today. But as it stands right now, I can take a CD-ROM drive from the 90s, use a cheap USB adapter, and plug it in to a USB port on a brand-new Linux or Windows or MacOS device without issue.

And even then, so what. In 25 years when I'm an old man I'll need to plug in my last optical drive into my 8 year old computer to read the disks and move that data off into the four dimensional hypercrystal storage mediums we'll all be using, and then I'll go into my cryogenic storage chamber to sleep for another 100 years and then transfer my data to the next media format when I wake.
PDF/A is a joke of a “standard” that does almost nothing that is promised on the cover. It is just a subset of PDF with limits on variable options like color representation, frozen at some arbitrary point in time, probably because people working with digital archives realized that they couldn't reach the moving goal, and implement the ever growing list of features. We may only expect programs producing PDF/A files to be less “creative”, and produce straightforward markup, but it's not guaranteed at all, because PDF/A doesn't address any of the real core format issues.

How do things work? From what I can tell (speaking as an American), we do seem to have imbued corporate leaders with a reverence classically reserved for religious leaders. And who else are we supposed to look to? God is dead, and 40-odd years of starve the beast has left the government with seemingly few policy tools to enact change; though as you note they can still change interest rates and print money.

What’s wrong with metal tubing indoors?

Outside is another matter. Those galvanized steel tubes don’t last very long underground, and the results are terrifying. And nothing in the code requires ground fault protection upstream of a 120V circuit running through a corroded steel tube underground.

Except, in non English speaking counties, the vast majority of people do not change the Accept-Language header (through various browser/OS mechanisms), and receive default results. But then experiments show that they are more likely to interact with pages when shown in the languages Google thinks you actually use.

If you go to myaccount.google.com/language , you can remove languages you don't actually speak, or turn off automatically adding languages altogether. It doesn't always work for everything, but it's a good signal.

> Sadly, multithreading is an afterthought for Emacs

It is, but it's usable. I'm actually amazed that, even after three major versions, the built-in threading is not used by the community.

Yes, the threads currently are not usable for number crunching in the background. And yes, there are bugs, and trying to do many things from the background thread doesn't work, sometimes in unexpected ways. You can still block the main thread from the background thread since some things block the event loop, no matter where they were started.

But, the threads do give you independent control flows. Whatever you cannot do in the background, you can offload to the main thread with a timer and a queue of lambdas.

The built-in threads are very, very bare-bones - it's around 15 functions, for threads, mutexes, and condition variables. They are very limited by their "mostly cooperative" nature. However, with a bit of sugar, they are usable for at least one thing: async processes and network communication.

In a background thread, you can "block" to wait for a child process to do something. It's natural and requires no macrology (async.el...). The same is true for network communication. You can block and wait for a response while the rest of Emacs does whatever. With just two functions, you can write code without blocking as if you used `call-process`. Sequential actions - call this, wait for it to finish, call that, wait for it to finish, etc. - can now be coded in a sequential way, without having to worry about callbacks, sentinels, and a poor-man FSM implementation that invariably appears in Elisp that doesn't use threads.

The threads built into Emacs, currently, are closer to green threads or coroutines, functionally, than to OS-level threads. But that's still a huge help in a bunch of important and pervasive scenarios. It's really strange that nobody seems to realize this.

With threads (as they are), the Continuation Passing Style compiler macro (in generator.el), and dynamic modules (for actual parallelism where needed) Emacs now has everything it needs to make it non-blocking by default. Of course, that would entail rewriting everything on top of these abstractions, so it's unrealistic - but for new code and packages? I think we're just one package (along the lines of dash, s, etc.) away from convenient concurrency and parallelism in Emacs. The problem, of course, is that someone needs to design and code that package...

The issue is that 1-2% of users of a random service might use screen readers. As an industry we’ve agreed that it often makes sense to drop support for browsers with more market share. Every screen reader is going to have an order of magnitude smaller user base than the browsers we’ve decided to stop supporting.

“No one” is going to do meaningful cross-reader testing. The only reason “anyone” does any accessibility work at all is the law (and thank god for it).

The Union had a much larger population, far more resources, and almost all of the divided nation's industrial production capacity. In most cases, it's factors like those that determine the eventual victor in a war (see WWI and WWII for good examples of this).

But the weaker party doesn't need to defeat the stronger one. They just need to make the cost of the war greater than the price the stronger side is willing to pay. That's how the USA won its independence from Britain, after all. Part of what made the price too high in that case was assistance from the French (it was the French navy, not Washington's army, that sealed the victory in Yorktown, for example).

The leadership of the Confederacy was well aware of this and had diplomats all across Europe seeking help for their cause. If they had succeeded, history might have taken a very different turn.

It's insightful to observe the difference between the emergent behavior of natural systems and the architectured approach often used in AI development. The focus on neural networks, while beneficial for certain applications, might overlook the potential of emergent, decentralized systems that could offer solutions for complex, dynamic challenges. Hivekit's work is a step towards exploring these alternative approaches, emphasizing the importance of communication and interconnectedness in creating effective complex systems.

After working on PDF document reconstruction for more than a decade, I often fantasized about inventing a cleaner and simpler alternative. After all, there are only three kinds of objects in PDF: shapes, images and glyphs. But it is all those little details that will get you in the end. A line - all you need is a coordinate and a length, right? No: is it solid, what is its width? Is its end point anchored on the left most part of the visible line, or does the thickness spread out from the anchor point? And is the end square of curved? If curved, what are the parameters of the curve? Are both ends the same? On it on it goes. And don't event get me started on glyphs...

PDF is a remarkable creation. It has some notable weaknesses, such as the fact that its color channel for images does not include alpha, and thus needs masks, but the fact that it covers so much visual complexity in a relatively compact form is just amazing. (BTW: Its graphics model is strictly from Adobe Postscript, but PDF content streams are not programs.)

One thing that bugged me while reading this article was the use of the definite article ("the PDF"). Since PDF is an acronym for "Portable Document Format" there may be a grammatical case to be made for the "the", but no one says "the HTML" or "the NASA" and so on.

It's the constant tug of war between the idealized security status where users have just enough access to do their jobs and the fact that it's hard to know the precise access you need until you get the task at which point the idealized process of review to grant access takes too long and really drags down your development pace.

At my job for example we don't have a separate support team for the ETL work we do so I have a lot of access I don't use unless things are breaking and then I can't wait for the access approval process to get added to database XXX or bucket YYY to diagnose what data has broken our processes.

This is factually incorrect, which is why you were (formerly) downvoted.

Right from the abstract:

"Persuasive content in online news contains elements that aim to persuade its readers and may not necessarily include factual information. Since a news article only has some sentences that indicate persuasiveness, it would be quite challenging to differentiate news with or without the persuasive content."

No, persuasion is not disinformation or something alike. While mileages vary, persuasion can be even seen as a necessary part of a democracy; thus, trying to censor it is ill-advised.
Boring Co. took billions of funding to solve transportation and it built a 2 mile test tunnel in Las Vegas and spent the rest of its money on God knows what.

NeuraLink has made 0 revenue, it's all investor cash.

xAI is tied to X and relies on investors' cash including Musk's own, as well.

SpaceX survives on huge NASA contracts, which it occasionally bombs (literally), such as the Starship, which should've been operational by now.

Tesla has cut prices like a dozen times this year to maintain demand, and all their profit last quarter was FROM SELLING CRYPTO. Their revenue crucially depends on overinflated self-reported EPA range (carbon credits) and subsidies from the govt.

So yeah, what is this "financial stability" you see, I don't know. He doesn't have a single company that has a normal, stable business model. It's all hype, memes, and subsidies. The man built the biggest house of cards the world has seen.

The reason he can't handle X is because big advertisers are smarter than retail investors who eat up anything he says, like he'd have billions of robotaxies and trillions of Optimus bots covering the Milky Way, or whatever is the latest grift.
Modern AA NiMH is so superior to the crap we used to have, and cheaper too.

I get that Li-ion charges faster, but there is something about industry standard batteries.

Hmmmmm. Maybe it's not so much AA that I miss, but the standardization. If Li-ion were sold and designed for swappable 18650 form factor, then we wouldn't need as many. The problem is that different Li-ion can have different specs and/or safety features (protected cells have slightly less current and are slightly longer).

Still, modern AA NiMH remains a standard form factor and capable.

----------

The other set of standard batteries is Lead Acid (6V 4.5 Ahr is standardized for example).

When did we become incapable of standardizing parts btw? Why are all of our batteries across iPhones and Google Pixels and Samsung Galaxies different?
That's true, but then contrast that to the treatment of the openai situation, where there were 1000+ comment threads devoted to vague tweets. (The "I Love You All" = Ilya thing was particularly wacky.)
