The graphene isn't pulled taut like a sheet pulled flat, but slightly loose, like a sheet slightly drooping, and the graphene naturally buckles and deforms.

Imagine air molecules colliding with the sheet causing buckles to form, invert, or flatten out, with the deformation popping up nearby.

Each time it buckles, a tiny current is generated. If it buckles in one direction, current goes one way, if it buckles in the other direction, current goes the other way.

Because of quantum effects - brownian motion - no collisions have to occur, the heat going into the graphene sheet itself is enough to chaotically produce buckling, with a direct transformation of mechanical energy deformation to electricity.

Heat storage is really easy. It'll be interesting to see how efficiency scales, in practice. If it exceeds modern thermoelectric performance, it's got a future, but this might get really high efficiency. The limit is the effective surface area of the graphene.

Because it's solid state, it makes low temperature / shallow geothermal much more feasible.

No gradient needed is the revolutionary phenomena here. It's a solid state quantum motion based electricity generator. The higher the temperature, the more rapid the brownian motion, the more power is produced.

What I don't understand is what would happen if you put a bunch of these inside a highly insulated really hot cavity. The paper suggests that it doesn't cool down while generating current, but that it cools while no current is being drawn. Is that just a "wtf, nature?!" thing or is something being missed?

I can't wait for this to be replicated.
In Cambodia, just days after the Khmer Rouge took power, they ordered 2 million people living in Phnom Penh and other urban areas to head to the countryside.

The idea was based on an extreme version of Maoism and a belief in the superiority of the Khmer people, the predominant ethnic group in Cambodia. Citizens were to be turned into traditional rural peasants, referred to as the "old people" by the Khmer Rouge. Urban workers and intelligentsia elites were viewed as "new people" and easily expendable.
I can think of several ways to do that, but they would require a very large sink or source depending on which way things go and you may very well end up holding the bag if the other parties are better at assessing risks in a very volatile situation than you are.
Salary isn't based on which degrees you have, it's based on what job you're doing. It's inane to compare a computer programmer's salary to a teacher's salary.

That aside, 68k is perfectly reasonable for a job with fantastic security, summers off, lots of vacation time where you get to work with children. Also, when I started working as a programmer, my salary was ~72k which is not much more and I had no trouble living off it. Of course the ceiling is higher for me but that's the market's doing.
Just a couple days ago it looked unlikely SWIFT would be involved. It's very possible Russia didn't expect magnitude of the sanctions being applied at all.

Putin is trying to go all-in with his last few chips. If he succeeds, he'll be in the game for a few more rounds. If he fails, he'll be out.

Hitler had allies. He had what was when he took power the best mathematics universities in the world (with comparable success in other areas; he eviscerated German academia, though), and (IIRC) the second or third-largest economy. Putin has a doomsday device that he doesn't actually want to use.
Because otherwise you decide that segments of the population shouldn't be heard. Democracy is literally "government by the people" - anything but universal suffrage means you consider some part of the population not people.
1. what was the army participation rate of the upper class vs the lower class? A cursory search seems to suggest the differential was 17% ("officer class") vs 12% ("largely working class enlisted men"). That's close enough that differences in army participation can drown the two out.

2. also relative to the army participation rate, is the suffering of civilians. If working civilians had to suffer rationing, starvation, and disease, while the nobility just chilled in their country side estates tended to be servants, that could more than make up for 1% (or whatever) of nobility dying in battle.

I don't think that is the goal. The goal is to stop the war and prevent further escalation. Of course you should focus on the ones who have power, but they are going to use the "general population" as shields. And you don't want to have useless sanctions just so you don't affect the common people.
What do you mean when you say you are protected from ketosis?

Ketosis is a metabolic state that provides the brain with an extra energy source -- ketones -- when glucose is levels are low. As such being unable to go into ketosis seems like a bad thing.
Do you trust opinion polls of people subject to autocratic regimes? Do you trust the people doing the polling? If you lived in Russia and you got a call from a stranger asking if you support Navalny would you say yes?

Seems obvious these issues basically mean all such polls are garbage.

There is no winners here but it's a huge improvement that Russia has to at least pay the price.
How is owning and trading cryptocurrency akin to dumping oil into a river? That’s a weird analogy. Obviously, the river is a public good that I share with others, it is not mine to pollute.

I am sure there will be a lot of sweeping of dirt under the rug in Silicon Valley.

Why?
It sounds like BP will be selling their stake to another party. So, BP will receive cash from the other party in exchange for shares in Rosneft. Whether the sale is a smart move for BP ultimately depends on two things: 1) the sale price 2) the expected future cash flows from their stake if they didn't sell.

My guess is that this will be a highly negative EV trade for BP because: 1) they're unloading a huge stake which will result in a depressed share price due to supply/demand imbalance AND 2) share price is probably already undervalued due to the fearful climate.
Ok, that's not our war.
When I traveled in the early 90's to Europe on business, I saw the currency changers selling rubles, but they would not purchase them ... Perhaps this will be at least short-term result of Ukraine?

There are no embargoes on currency futures in the US. So far as I know there aren’t any embargoes on delivering rubles as part of a futures cash settlement either. Getting those rubles may get difficult. But currency futures are dollar cash settled…
And that is assuming they work, which estimates are very much varied about. Obviously Russia isn't going to help with verification here.

Considerably more numerate coverage, it's WELL-informed snark.

Is snark the exclusive domain of journalists? They are certainly the world's main supplier of it. But it seems like everyone else should get to play too.
There is no embargo. At the moment, US has imposed sanctions directly on Putin and other top Russian leaders, and a small number of Russian banks have been cut off from Swift. You are free to buy and sell Russian currency and stock if you want.
They will care when it goes from 85 rubles to the dollar to 1000 rubles to the dollar.
My understanding is that futures are simply a contract between two parties. Ruble futures don't necessarily have to interact with Russia or any Russian individual.

Alternatively, they don't want anyone who isn't going to play nice to reuse the code.

Much like proprietary software, or any other software license, you have to follow the rules for what you're using, and in this case the author wants to make sure any changes get contributed back.

Also, this doesn't seem like a good usage of a throwaway account as per the guidelines.
Also, over 80 years of technological advances complicates the comparison quite a bit.
> I wonder if the Ukrainians could try to make it super easy and somewhat attractive for Russian soldiers to defect.

That's what they constantly calling for: surrender if you're in the action. It's very attractive when the alternative is getting shot. Of course, there's matter of what to do with POWs after this is over, whether to kick them out back to Russia from them to taken to the wall or to the gulags. But that would be later.

The problem is acting on that when you're a soldier. All soldiers of all countries are brainwashed into following orders, not making they personal educated decisions about every operation they participate in. It's also a bit hard to just go and surrender when you're not cued in into what's happening and was not following news for the past week from the comfort of your home. It's a bit hard to surrender immediately when your first contact with the other side starts with a strike on your column and gunfire in your direction.

Or he tries the nuclear option. I would not longer rule that out. He has already lost the first round.
I too have concerns about charter schools and I suspect that they will end up making the American school system better for a few kinds of families but even more unequal, segregated, and expensive.

However, your assumptions about the motivations of charter school proponents seems uncharitable. The proponents I know come by their position honestly -- they truly believe that vouchers and charter schools are good solutions to the problems facing our nation's students.

I highly doubt Putin is going to end up being dead, outside of a military coup or uncontainable riots where angry mobs breaking into the Kremlin.

This upcoming week is going to be crucial - peace talks have technically started, but it is unknown if Putin’s ego will cloud fair judgment leading him to double down on war efforts. OTOH if Russia’s oligarch bank accounts are heavily impacted, then they might be able to sway Putin away from doubling down.

China isn’t showing signs of aggression, which provides major relief to the international markets.
Yes. (salted) Butter is magic.

I am French and a few friends have remarked that I use a lot of butter in my cooking before tasting and telling me it is the best ... they had.
> summers off, lots of vacation time

This comes at the expense of having absolutely no flexibility during the school year and usually plenty of long days & weekends, and summer has things like professional development / continuing education keeping it from being a long work-free block.

It’s not bad but it’s not a compensation game changer. One other thing to remember: for a teacher, being out sick is almost as much work as a normal day. The tempo of a school year means that a lot of people need a couple weeks to unwind at the end of the year.
US is not afraid of China.
It's important to realize that the concept of a "galaxy" is arbitrary. Specifcally, it's not like stars suddenly stop and that's where the edge is. It's gradual.

And while the intergalactic medium has very little matter (often quoted as ~1 atom per cubic meter) it's not evenly distributed and there are stars. In the Milky Way stars are on average ~5 LY apart. In the IGM it's likely this number is more like ~1000 but it's really ahrd to say for sure.

Do the math. 1 LY = ~9.5e15m. A cube 1000 LY on each side is ~8.6e56m^3. The Sun is ~1e30 kg. For simplicity let's say that's all hydrogen. Avogadro's Number tells you thats 6e23 atoms per gram or 6e57 atoms in a space of 8.6e56, which comes out pretty close to 1 atom per cubic meter while there still being stars.

So the gas halos of the Milky Way and Andromeda galaxies are arugably already "colliding". I'm not sure this is a useful description of a galactic collision. There are gas structures in the IGM. At what point do you consider something to have collided exactly?
But we all do consume too much for it to be sustainable. While I agree that we primarily need regulation, mostly on industries and the production of goods and services, our collective individual choices do matter. And I can’t credibly fight for regulations while driving a huge SUV or crisscrossing the world with jet planes.
> can honestly believe that a bored roulette croupier could reproduce an outcome by consciously (or unconsciously)

The fantastic book, The Eudaemonic Pie, mentioned elsewhere in this thread, describes another groups attempts to beat roulette with prediction.

Along the way they encounter a croupier who always bets his tip money on 17. Why? “Because if I do everything just right, I can actually hit seventeen. Not that I can do it every time, mind you, but I can get close to it. I set the wheel going at a steady rate, and then I flip the ball in this nice regular way when the zero is lined up in front of me, and I swear I can hit seventeen with better-than-average odds.”
Or the reason for sharing isn’t anything about reuse. Perhaps it’s about encouraging similar uses or about public accountability.
The problem is that people no longer believe that there is no risk of a similar document being written in the future, similarly saying that it would have been preventable, only bearing the name of their home town.

>No gradient needed

Wouldn't the net current be zero with no gradient? We're not violating any laws of thermodynamics here.
iirc when the 2008 financial crisis hit, Putin said that he'd never let Russians lose all their savings like in 98 - so much for that promise I guess
Still not following. It's not "hubris" to believe in the truth. It's not "moral relatavism" to believe lies, that's just "being wrong". The fact that people lie to other people isn't a license to throw out the concept of morality! Quite the opposite in fact.
Well, we know that in many dictatorships support of the leader is marginal (e.g. just across the border - Belarus). This does not seem to be the case with Putin.

And yes, you can say you don't like the war in a poll. It's not North Korea.
American war propaganda = 70-75% fake sensationalized news, Russia war propaganda 95-99% fake. Just FYI.
How? Again: who internationally would want to give up Bitcoins for Rubles, when you could instead use them on literally anything else in the world. There's no expectation that Russian currency will go up in value in the near future, and definitely no expectation or even legal means to trade physical property.
The biggest problem with this is that no one is maintaining all of those old userlands, so when you use an old userland, you are reintroducing tons of known and fixed (but not backported) bugs, including many serious security issues.
Where does the energy come from? The environment surrounding the chip?
it may not hurt the elites, but it _does_ slow the Russian war machine in the medium to long term.

In fact, arguably one of the biggest things we've "learned" from the past week is that we (the west) have been _way_ too economically entwined with Russia for decades, and that is what has enabled this aggression.
Is there any realistic simulation or artwork projecting what it will look like?

Eh, we've spent the last few hundreds years abusing our lovely language.

And the only reason it ain't longer, is because if you go far enough back, it's different enough that we can't call it our language anymore.

Language evolves and political correctness is just one force amongst many, and not even a new one:

The environmental impacts of cryptocurrencies have been discussed at length here on HN and elsewhere.

Similarly, reining in war crimes is a public good, and sanctions are not yours to violate.
The only time they get their comeuppance is when the peasants come knocking on their doors and want their heads and usually things don't progress that far. Then new bad humans take over and start the cycle anew.

The communication overhead should not be constant - it should be proportional to the scope of responsibility.

As a full time senior engineer I’m responsible for oversight and guidance on three separate work-streams, so I have to go to all their meetings. If I were part time then I could be involved in just one of them, and go to only those meetings.
> A successful engineer at well known shops will fail a pressured evaluation where a google engineer will pass the interview. It make sense because google's interview process is harder.

Nonsense. Googlers will pass bc they on average ship more code than an average eng at all other companies i worked for combined together. More code written -> more practice -> better outcome in coding sessions. It’s not really a great mystery. I can only assume same is true for fb based on the outcomes I’ve seen personally

If the issue is income/wealth gaps in society, then that is better solved by implementing huge marginal income/wealth taxes such that the can be rewarded hundreds of millions of dollars, but they will only end up with a small portion of it.

There are other costs that either make very wide OoO more difficult or more costly. x86 has a lot more flag-based instructions compared to Arm. That adds more dependencies that the reorder engine has to sort through. x86 variable length decoding takes log(n) in decode circuit depth, which either forces a longer pipeline or limits clocks. And obviously AVX512 units are just huge because a decision was made to make them the same latency as normal MUL/ADD/FMA. And x86 designs have to scale in clockspeed from server / tablet (~2.5GHz) to desktop and high perf laptop (5GHz+). That forces suboptimal designs like the 5 cycle L1 in Golden Cove. Meanwhile Apple has a 3 cycle 192kB L1.

I think you are not alone in that. But that only serves to illustrate that we tend to collectively forget the lessons from history way too easily.

But around me I see people - younger people, mostly - go around like the bottom just fell out of their whole worldview.
