The race for breakeven fusion is heating up, and it's exciting to see. That old adage about reaching breakeven being 'always 30 years in the future' is actually, finally looking more like 5-10 years. Relevant projects, all tokamaks: The largest ever fusion reactor so far which is being built now -- ITER in France, then there's MIT/Commonwealth Fusion's SPARC (they just demoed a type 2 superconductor magnet that developed 20T in its rather large borehole), China's EAST reactor and its recent 200+ million degree temperature and confinement time records, and the venerable JET reactor in the UK, which still holds the Q record of ~0.67 with D+T and they are prepping for another tritium run. These projects are some of the leaders in the field, amongst many others.

The stellarators are also fascinating projects though even more geometrically complex than tokamaks are. The Moebius strip-like twist allows them to impart stability to a ring of plasma in ways that tokamaks can't. The Wendelstein X7 in Germany and the Large Helical Device in Japan are the largest and most recent examples. The Princeton Plasma Physics Lab has a novel stellarator design called NCSX, which interestingly uses coils and arrays of permanent magnets.

The advent of type 2 superconductors at scale will contribute greatly to this speed-up to acheive breakeven with tokamaks and stellarators. The much smaller and newer design MIT SPARC (which will use the more recently developed type 2 superconductors) might even beat ITER(which uses type 1 superconductors) to Q=1+!

Yes. You only need to be “online” periodically to check for fraud, which is a task which can be relatively trustlessly delegated if need be.
It’s a valid question, given that US perpetrators never meet justice and the society isn’t even trying to do anything about it.
> and it raised the price of used cars

since the point of the program was to stimulate production of New cars, which it did, creating an increase in GDP and jobs, the experiment was a success.

If Biden forgives student loans it will not lower the price of tuition. Since the point of student loan forgiveness is to help people get on their feet, and buy houses and cars, it not lowering the price of tuition would also mean a success.

I'm guessing you have a house mortgage. If I pay that off for you, will it lower the price of your house? I guess there's no point in doing it then. Because you wouldn't take that monthly mortgage payment and instead buy more stuff or invest in stocks, boosting the economy. You would clearly spend it on sponsoring a super-spreader own-the-libs rally.

Turns out you're right, I was working from app notes which were trying to sell sync bucks. (Not that that's hard to do, sync bucks are awesome.) I do think there are a few pathological startup cases that get easier when the output can sink current, but while those cases are easier to get into with bipolar rails, they still ought to be quite rare.
Obama started the conflagration in Yemen. He overthrew their leader of over 20 years. He then bombed Yemen to the stone ages. In addition he armed the Saudi and other proxies with weapons to wreak havoc and genocide in Yemen. The Yemen story is like Obama’s grim reaper legacy in Libya (he even help create slave markets there), Sudan, Somalia, Africa and elsewhere.

The overthrow of Yemeni President Ali Abdullah Saleh by Obama which was the first step to destroy Yemen:

This type of failure could conceivably knock us-east-1 down, but I think it could be pretty easy to recover (precarious update? roll back!). I think Bray is considering total obliteration of the us-east-1.
The New York Times and other publications published multiple pages of the Pentagon Papers, they just were unable to realistically publish the entire leak. If you read the Supreme Court case involving the Times, it clearly says it was about publishing the contents of a classified study, not writing articles about a classified study.

There is no content difference, both contained leaked documents and articles about them, the only difference is the limitations of the medium.

Rust Crimes: Enum Ints
"-o" is mostly "--remove-assertions" already, so that wouldn't help.

While today's use case for assert is unit testing, the actual killer feature of the keyword is that it's removed only from prod.

The idea is that you can write things like function contracts, that are expensive, but only exist in dev.

Now, if one of you dependencies use assert for something they expect to still be in prod, which is the problem we are talking about in the first place, "-o" or "--remove-assertions" will strip their assert too, breaking their code, and hence, yours since it depends on it.
so nothing to see, please keep walking?
Even though they really, really shouldn't. As you undoubtedly know, it's a terribly dirty fuel source that is destroying the planet. When I saw this headline, my gut reaction was actually "good -- I hope that makes other fuel sources more competitive". I then realised that I am not an economist, and that it would have the opposite effect -- increasing production.

One thing I'd love to see come out of COP26 is an internationally agreed minimum tariff per ton of CO2e, including electricity weighted by its means of production. We want coal to be very expensive to buy (and very cheap to sell).

> The latter is an inevitable consequence of first past the post voting and plurality-majority representation, rather than proportional representation. Until the US moves past these systems, it will always be a game of voting for the lesser evil.

PR has its own problems and the US would do better to adopt range voting to break the two party system, but any system where parties exist is still susceptible to the original problem.

If Party A does something bad in favor of a special interest, Party B might gain support. But they can estimate how much support they need to control the government. Now that they have more support, Party B can do some other bad thing in favor of some other special interest and still be competitive. If you add Party C to the mix, they still have the same incentive and opportunity to abuse their power.

You can have a party which always makes the decision that maximizes social utility, but you can have that in a two party system too. For that party to win votes, you need voters who are willing to elect that party instead of the one that promises you that you'll be the beneficiary of the kleptocracy.

But these are the same people who do the right thing even when no one is forcing them to. If you society is full of them then you don't need the use of force to make it happen. If it's not then an elected government will represent the majority of selfish jerks.
The Rise of the ‘Vietnamese Rush Limbaugh’
The two natural disasters I’m most worried about are:

1. A Carrington-scale solar storm. This was talked about in the article. We have not had any significant solar storms affect earth in the last 150 years and basically all of our electrical, computer and communications infrastructure was built since then. Grid operators are not optimistic about the idea of starting up the entire electrical grid from nothing as it has never all gone down before.

2. A repeat of the recent historic activity in the New Madrid seismic zone. This is a place where historical accounts talk about aftershocks lasting for months but in more recent times it was not so seismically active so eg building codes don’t sufficiently prepare for this. Fortunately there is not that much economic activity there but there is still a lot.

I guess number 3 would be the “big one” in San Francisco. Though the fire risk isn’t so bad nowadays I think.

I'm trying to avoid any association with "classic liberals", cryptofascists by another name.

I think Yugoslavia is the better example fwiw - a society where there was high living standards and high degrees of freedom, arguably higher than in the West. They had greater economic freedom as all companies were worker-run coops with leadership elected by the workers competing in the marketplace; compare that to the autocracy of the modern capitalist workplace! They also had the freedom to travel both the Communist and the Capitalist blocks, but that's not as relevant today anymore.

I agree with your comment about having to look forward though. I think the ideal scenario would be fully automated space luxury communism - e.g. Star Trek, but baby steps ;) We'll have to make sure to avoid falling to deep into capitalism and its systemic descent into corporatism, then fascism though as has happened every time that system has been tried.

To me, the important litmus test is when bitcoin gets definitively linked to a specific terrorist incident. Now, terrorism in the West is mostly out of fashion, except US rightwing extremists, because it's hard to have a death toll that anyone would notice over COVID, but that's not to say it won't happen in the future.
As I understand it the stack size limit is because a process's threads share the same address spaces so basically where would you put all their stacks? With one stack you just start it from the top of (virtual) memory and put the heap at the bottom and when they meet you've run out of memory. Infinite stack!

But with lots of threads there aren't enough spaces for them to start from. At least on 32-bit. On 64-bit I think you could have effectively infinite stack, or at least very very large (like 1 GB) stacks. But as far as I know nobody has bothered to do it.

I guess an alternative solution would be to put the stacks in different address spaces somehow, but that could get very complicated (now you have two kinds of pointers). Are there any old systems that had separate heap and stack address spaces?
Since HN generally does not like mentions of Bitcoin, here are some stats.

Bitcoin was launched 12 years ago, reached $1'000'000'000'000 monetization this year (>1.5x larger than IMF), exploded interest and funding for cryptography and p2p networking over the past 6-8 years, and is marching towards reaching monetization of gold ($11T).

Lightning network runs over 3 years already and growing its capacity exponentially, offering truly "digital cash" capability: no trusted third parties and instant transactions.

Yes, Bitcoin is volatile and it will remain so until it saturates the market like gold did, and every person has as much bitcoin as they want to carry, relative to other assets.

There's always been the tacit assumption that using a package manager implies trust in the way that packaging is handled by that manager. Often people who handle packaging dozens or hundreds of packages over years actually ARE much more aware of the security implications of decisions made by developers of individual pieces of software.
It's a mess because for the average joe such as myself it's very confusing and foggy.

There's an Oracle jdk whose usage terms need to be deciphered using a lawyer to understand precisely when and how you can use it. So much that the average advice is to not use it. Like if they told you "hey, node.js is cool but don't use the one from those who maintain and develop the code". This would be a huge red flag for any other language than Java, which can leverage 30 years of sunk costs for companies that now will not switch lightly to something else.

The alternative builds are good, yet not official and they might introduce thin incompatibilities or different behaviors. They should not but this whole article suggests that they actually do.

The simple existence of articles like this one testifies that this is a mess for a lot of people.

Agreed. This was a fantastic class when I took it. The textbook written by Sipser is also extremely good and could stand alone.

Yeh fair. I wonder what duration of outage would cause a spiral of the mentioned economic and social effects. I'm sure a fix made within a few days would not set the course of the economy on a different path but it's interesting to consider what duration or degree of an outage would.
We would need at least _one_ chain of bank - payment processor that only works on payment fees and has a public mandate of letting the maximum transactions go through.

Challenging it in court is an impossible burden for most people, so the most important thing is the default. Do we want the bank to assume you're a criminal, or do we want to assume you're innocent and make the police be the ones to prove if you're not?

I think that mostly depends on how much data you generate in a day. If sending backups out increases your bandwidth use by 5% then it's pretty easy to throw that into cold storage on google or azure or local or all three.
Competition is the way capitalism works :-) . And I've seeing absolute monopolies doing far worse. Examples: the Cuban communications monopoly[^1] and their national airlines.

That said, airlines are between the sword and a hard place, and I expect it's going to get much, much worse as climate regulation kicks in the next few months. If you want to fly to some remote country for tourism, do it as soon as possible.

I have a thumb rule. If it's anything from nyt, medium or dev.to, I glance at the comments to see if it's worth it. There is usually someone who gives the tl;dr in the first few comments.

“Some”? That doesn’t sound “highly critical” at all.
I was handed a policy document at my previous job that said: "In the event <CEO of provider> spits at <CEO of ours>, we must be able to migrate in 2 billing cycles".

The reason isn't the spit, it's to prevent being so locked in that the provider can rent seek; but there's also an element of agility in that. If you can turn to AWS and say "Give us a good deal or we walk" and.. you know, you actually can walk... then they're more likely to do that.

This is the same reason broadband is fairly inexpensive in Sweden, the building will negotiate as a unit to an ISP and get a group deal. Bulk buying in this way gives a lot of negotiating power. So for a publisher to be able to move all titles to a new provider in 2 cycles: that's negotiation power.

If you can save 2 months of developer time in a year by switching providers, it behooves to do it; and cloud resources are _expensive_ I recently specced out an instance for gitlab which is currently living on a VPS, it went from $30 to nearly $800 on cloud. (Though admittedly that $800 variant would be more highly available.)
