I wonder what the limits are on transmitting power around the world? Like, if we wanted to connect Northern Africa to the North American power grid, how feasible would it be, and what would the losses and power capacity be?

It seems that with all the interest in using ReBCO tape in tokomaks due to its ability to transmit more power at higher temperatures than the materials that preceded it (used, for example in ITER) that it could be used to transmit power over long distances. Has anyone actually done it yet, or is it just too expensive? (Apparently the current capacity of superconducting cable is finite; if you run too much current through it, it'll transition to becoming non-superconducting. So maybe the amount of ReBCO tape needed per unit of power or the amount of active cooling needed makes it impractical.)

Eventually, to be able to usefully transmit power from daytime sun to nighttime will require crossing oceans. Which I imagine would be tough to do with a cable has to be actively cooled and work for many years without maintenance. Maybe for my hypothetical North America to North Africa route, you'd run a superconducting cable down through Central and South America over to Brazil, then have a normal high-voltage DC line across the Atlantic, with another superconducting cable that crosses the Sahara.
The USA got rich because of unbridled capitalism. Then richness trickled down through generations of companies while regulations caught up and their government became a behemoth not dissimilar to the ones living in EU and that the USA was running from.

Nowadays the USA jurisdiction is comparable to the EU one, but they still have more $$$.

Probably not... but ancillary benefits like this can lower the selective pressure against trisomy 21, so that it's less likely to go away.

That's the thing. Something rare like Down Syndrome only has a very small selective pressure against it, and it's really easy for other effects to remove a fraction of it.

So things that seem ridiculous like this assertion or the "super uncle" theory about homosexuality are not so easily dismissed when one really thinks about them. Of course, there can be selective benefits from genes with a propensity for (forming trisomy 21, having homosexual individuals, etc) when the specific condition doesn't manifest.

Not at all. The technology for hydrogen energy storage is (with the possible exception of cheap electrolysers) is off the shelf. It's not widely used not because it's not available, but because natural gas is cheaper to store and burn when there are no CO2 taxes. But the CO2 taxes will be raised enough to push natural gas out, if we're going to control global warming.
"For example, airlines just want to fly passengers. They don’t care who puts those butts in seats"

Not sure who you talked to, but I've never heard that before. They all want to sell more direct and forego GDS fees and/or other types of fees and commissions. I'd love to see a quote from an airline VP or above that they don't care about their distribution model, boosting direct sales percentages, etc.
> 4. The requirements are often flat out wrong.

I have used nfshost for hosting multiple sites for over a decade. They're a fantastic service that's simple, secure, and provides great, fast support.

They recently published this blog post: https://blog.nearlyfreespeech.net/2021/01/19/free-speech-in-...

After reading this, I made the decision to move my hosting elsewhere. I have never hosted content that is even remotely political, and have no intention to do so. I had chosen to patron nearlyfreespeech based upon the belief that their conception of 'freedom of speech' matched my own. I believe 'freedom of speech' is not just a convenient vehicle for expressing my own political ideas, it is an important political idea in and of itself. I believe that the freedom for individuals to express their ideas without censorship is integral to a free and intelligent society. This post of theirs demonstrates that I had clearly misunderstood their beliefs.

It's clear that 'freedom of speech' is a controversial notion in today's society. If they market their service based upon their respect for so-called freedom of speech (it's in their name), I don't know what kind of crowd they expect to come. I came not out of a need, but based upon my political views. I imagine I'm a minority. I'm not interested in a host that markets itself in such a way, and then demonstrates that what they _really_ meant was that they want an environment where you're free to agree with their views.

With fixed mortgages this is true, but if you get an adjustable rate, you’ll need to refinance and that’s when you need to requalify and meet loan to value ratios.
I hear you on this. I loved the Ramona books when I was a kid, but I also got so frustrated with Ramona because she acted so irrationally. My favorite was "Beezus and Ramona" because it was told from Beezus' point of view and I identified with her much better. I think maybe some kids are just Ramonas and some are Beezuses.

Maybe you could have been Claude Shannon but he already solved those things. Sometimes coming later, the low hanging fruit has already been picked.
I will repeat the reply I gave elsewhere to this argument:

Dude. You are falling back to the "if it isn't already being done, it can't be done" argument. Please stop this foolishness.

Hydrogen is being stored in a few places. That the storage isn't larger isn't because of any technical obstacles, it's because there's no reason to store it now. In particular, when we can burn natural gas without CO2 charges, using the hydrogen for energy storage is pointless.

This doesn't mean hydrogen CAN'T be stored, it just means the market conditions for widespread adoption of an off-the-self technology aren't there yet.
I know what I mean (-:

At a certain point, you've got to stop pumping the gas. You want the company to outlive you. Gas needs to get pumped after you're gone. You fade into the background and replace yourself; others carry on your legacy. You cash out and ski six days a week or whatever.

Edit: some legends are bullshit. Scale that up and it's called "toxic culture".
> Leadership failure? How is your compiler doing?

I'm enjoying rustc very much, thank you! I hope that gcc-rs will catch up soon, but until then, I'm thrilled that the Linux kernel compiles just fine with Clang and there are millions of people running Clang-built kernels, because it means adding rustc into the mix is straightforward.

I'm also enjoying using libLLVM in projects from Numba to llvmpipe. Numba is helping us speed up some serious research computations at my current job, and llvmpipe solved a major practical problem with GNU/Linux on the desktop at a previous job. Those projects could not have been built on top of GCC.

I'm also enjoying all sorts of analysis tools that use libLLVM and libclang (include-what-you-use being a very simple example) even on code that I compile with GCC for legacy reasons. If you look at the linked threads, RMS wants such tools to not exist, or at least to be hard to write and buggy.

> Apple didn’t develop LLVM. It was developed at University of Illinois at Urbana-Champaign.

Not disputing this. Apple didn't develop GCC either. They contributed to both.

Stallman was worried that if he made GCC either permissively-licensed or modular, companies like Apple would privately fork the compiler and not contribute back. He thought it was a vindication when NeXT contributed back their Objective-C frontend, which they were going to keep private until he threatened them with legal action. But UIUC made LLVM both permissively-licensed and modular, and Apple contributes back to it nonetheless, with not even the slightest legal obligation to do so, making a killing while also producing a free software compiler that is superior to GCC.

Everything GNU tried to do by technically hobbling GCC, UIUC actually did by producing a superior product in LLVM. My whole point is that Apple didn't develop LLVM, but that they contributed back to it because they saw a financial advantage in doing so.

> RMS has a strong political stance and the result is software that has benefited billions in one way or another.

Correlation is not causation. I'm not claiming that GCC was unsuccessful; I'm claiming that RMS's strong political stance did not make it so.

And RMS would be the first to argue that mere popularity is not the sign of a software product's success. GCC is supposed to protect a user's freedoms more strongly than LLVM, yet a user is practically more free with LLVM; for instance, I am free to get the AST of my own software. For those of us who believe in the ideals of free software - which includes both me and RMS - this is a sign of a strategy that failed, somewhere, that should prompt some reflection.
how long before I can buy a Tesla for 50% of what one costs now? If the batteries are going to get so cheap we should be seeing some great price drops in electric cars. If not ... why not? And that reason will probably apply to battery energy storage too.
I agree there's nothing to rule out your theory. Likely we will never know. But then why authorize sharing the story?

Specifically I don't think the owner thought it was likely, just a concern he couldn't shake. Probably he relaxed as soon as the consultant didn't make excuses, and tackled the job—extracting the binary from an unlinked inode is definitely not showing reluctance. Pure speculation, of course.
For a like-for-like example, the Galaxy S10 released in 2019 like the Nokia 7.2 is 4.14.212.
Sorry, not very convincing. As they point out, peer review sources needed. The peer review sources they cited are either speculative, side issues or informational, but not evidence.

This entire debate is silly without numbers, but even worse it's missing the point - 38% of UK CO2 is from heating. Most of CO2 is produced to heat and cool building while the stand, not to build them.

Even tiniest improvements in quality of building, it's heating system and insulation will result in dramatic changes. This favours something well built, well insulated, with a heatpump, high thermal mass, and most importantly with heat recovery ventilation. Not hastily constructed crap that goes to shit in 30 years.
Pros: no government "middle man" taking a "cut" (although I'd like to see how much % was used to administer the trump/biden checks, for instance)

Cons: Totally arbitrary. Have a generous employer? Great! Stingy employer? Sucks for you. I'd also imagine that whether you'd get this kind of "relief" depends on your job, kind of like how waiters get tipped but fast food workers don't.
He was writing one paper a week even after he became blind!

"So prolific was he that the journal of the St. Petersburg Academy was still publishing the backlog of his papers a full 48 years after his death." – Euler: The Master Of Us All

p.s. Last year I read his Introductio in analysin infinitorum (1748), "one of the most influential mathematics books of all time", which made the function concept basic in mathematics. Polynomials, trig functions, exponential functions, the logarithm function, etc etc - doing amazing things with infinite series. It was hard to believe it wasn't a thoroughly modernised text, everything looks so modern, but it's just that he introduced a lot of our notation. And he explains things so helpfully and modestly. A joy to read, highly recommended.

hey, kristian from the workers team here - i wrote these docs, so this is good feedback :)

we don't have any plans to get rid of workers sites! but we do think that for most people deploying static sites, pages is a better fit than workers sites.

when we do talk about the future of pages versus workers sites, we're generally talking about making it easier to deploy serverless functions /with/ your pages sites - providing better tooling and DX around that is a super high priority for us.

the interplay between workers serverless functions and static asset serving via workers sites is still a really strong use case (and IMO a thing that workers is uniquely capable of doing) that we don't have any plans to shelf. again, i wrote the docs here so this is on me if it came across as "we're getting rid of workers sites" - i'll take a shot at improving these docs and helping clarify that next week!

I like pen and paper because it's secure. It's an unhackable, hard to forge tamper evident record.

There's a stupid number of problems where the easiest answer is "pen and paper" because while it's hard to make redundant, it's completely security auditable.
Yes, that's what I said, and even included the second link to make that more explicit. I don't mean to imply that the wealth gap in wealthy countries is decreasing. The point I am getting at is that it's far more difficult to make the argument that the wealth gap is increasing, full stop. It's quite likely that the vast majority of the world will live in countries where it's decreasing.
I guess it depends on when we talk about it but it certainly matters if it is the janitor / secret hacker in the building or someone from somewhere that you have no legal recourse.
I was a founder of a VTF (downtown project VC) funded company. We had an exit. I can’t vouch for the rest of the companies but hard drinking wasn’t part of our culture. Careful painting all of us with that brush. I was around for the first Vegas Jelly, and was funded in 2012 so I would be part of the “surge” you defined.
That's what I said: that they got a special exemption (which is not part of ARM's official license offering) to allow them to do this for embedded use cases (iOS devices), which implied that they wouldn't be documenting or having other people use these instructions.

The problem is that the M1 threw a wrench in the works because now suddenly running non-Apple code that can use these instructions is allowed, and everyone else can see that they exist, so suddenly the existence of that special exemption is public.
I'm taking it to mean union employees wouldn't get new grants. Which makes sense to me - I have a hard time squaring how you can be in a union with an adversarial relationship to management, whilst at the same time being an owner of the company. It's one or the other.
Probably should mention that the US constitution was written largely to protect bond speculators (against state legislatures trying to protect debtors).
You can use older devices safely. Switch to iOS. My iPad Air 2 from 2014 still receives every update. It’s clear that android vendors have no interest in long term support and apple does. So I send my money to the company that works the way I want.

I truly don’t mean this to be provocative. The Ramona books weren’t “books for girls” per se, but the default perspective in literature, especially kids’ lit in that era, is male. That it’s a book which appeals to everyone, but is written from a girl’s perspective, causes male readers to wonder if it’s “for” them.
We've been using hydrogen in the chemical industry. We haven't been using hydrogen to drive combustion turbines very much, and even then it's in a mixture of natural gas.

1. Demonstrably false. All of those nations I listed have huge offensive capabilities as well as plans.

2. Russia’s military is much better equipped than Italy’s, so pure GDP numbers probably don’t matter 100%.

3. US generally enforces international law, and the world has never risen to this level of stability in the past few hundred years. Almost all parties have benefitted. China hugely. You’re just assuming that this stability can exist in a world of autocratic ethnostates that have no hard rules imposed?

Your comment is clearly naive and unread.

Capitalism is not exploiting anyone. Capitalism is purely about organising the economy around voluntary transactions.

Exploiting, enslaving and murdering is purely what socialist countries do - and they can get away with all of this, just because they can socialise the cost of all their evil deeds and force people into paying them money.

The only reason capitalism hasn't collapsed is that it's the only way to have a profitable economy. The crooks that you call government recognise that they can steal only so much from the economy before a country collapse.

I'd also argue that we've experimented with elements of socialism and elements of capitalism for the entire existence of civilisation.

Communism can't work unless you have either perfect individuals or a tyrannical states which force resources distribution. In the real world, you end up with socialism. Because people are not perfect, the government which will redistribute resources won't do a perfect job in the best case and will just be completely corrupted in the worst case.

And still, communism was attempted. When did we ever attempt to have an entire capitalist society without a government to ruin it?

Like most things, it depends on your workload. If all of the files are written all at once when they created (e.g., no slow append workloads) and the files are all the same size, then that's a very "friendly" workload that will be much less likely to suffer fragmentation. But if you are creating and deleting files that have a large range of sizes, and some files grow gradually over time, then free space fragmentation will tend to occur much more quickly.
Just to augment or explain in a slightly different way: Coming in with the most abrasive terminology you can, and being aggressive convinces no one. People who disagree don't read what you say. And it can even upset people who agree with you. It just destroys communication.

I hate it when people do this. When I agree with them, I cringe, because it means my milder argument will not be heard. When I disagree, it has its intended effect and provokes me and leaves me angry.

I suspect that the wild price increases in Texas are from people not realizing the price had gone up and continued using electricity as usual. With demand not dropping, that just continues to push the price up.

I doubt this would happen a second time, as people wise up. They'll either monitor the electricity prices, or put automatic shutoffs in place if the price exceeds $xx.
