Going by inflation adjusted market cap values, it certainly looks like the financial facet of the AI companies alone are bigger than both those events.... This is going to be beyond messy...

The issue is that as dumb as it is, SATA ssds are still a big part of the consumer market.

Even though nvme isn't appreciably more expensive to make, it's still used as a "premium" product., and SATA is a product tier to capture budget market whole protecting their more premium market.

This move is a clear symptom of the real issue. Manufacturers shifting as much capacity as possible towards big datacenter buildouts at the expense of starving every other market for these products. Trillions of dollars that will pay whatever it takes competing with a more rational market

So our utility came out and said they have to raise residential rates by a rather large amount, largely because so many data centers are demanding so much power they need to upgrade, so residential rates have to fund that..

Well the explanation would work for one election, 2024.

In 2016, he was a terrible choice on so many fronts, but no especially strong reason to expect he would dramatically shift inflation or pay. And on those specific metrics, his first term was mostly typical, except pandemic, which people can believe to be an utterly freak event beyond anyone's control if they still wanted to vote for Trump.

The global economic shock continued and was exasperated by war. Biden had little to do with it, but it was on his watch, so he gets saddled with blame, so to the extent a voter just thinks about their personal economic situation, they vote for "not the current leadership".

So this term has been marked by utterly predictable economic problems that everyone told them would happen, but they didn't have first hand experience to trust that, and Trump's rhetoric resonated with the "I know smart people say it doesn't work, but 'common sense' tells me get rid of immigrants and tariff all imports and things will be great, making American jobs and getting rid of foreigners taking the jobs".

So now they get to see first hand why those common sense thoughts don't actually work.

Still. I predict next year they'll roll back tariffs to try to create a bit of deflation and also cut checks to everyone to make them feel like winners in the moment as they decide midterms.

Yes, the government that was accused of abducting a family is in the right, because that same government says they are treating that family well, and no, no one is allowed to independently verify that, but obviously you have every reason to take our word for it

Whatever the situation is in Venezula, it's not going to be a good thing for America to get entangled.

Hussein was a pretty bad dude, but our intervention in Iraq ultimately was bad for America and didn't exactly make things in Iraq better.

Yes, indeed, it's open ended and on the surface it is consistent with a plausible follow through on existing decision.

Though the prospect of suspiciously selective enforcement comes to mind, in the midst of this very specific scenario they decide to execute a seizure that is conveniently adjacent to the boat strike operations.

Mr. Rubio’s order cited the origins of serif typefaces in Roman antiquity.

So, it's best because it has "Roman" in the name. And if they like "Roman" salutes, clearly they want "Roman" fonts too.

So assuming 10 lbs of force, as measured 1 meter away from the hinge, you have about 44.5 Nm of torque. Assuming each door opening was about 90 degrees, then you have about 70 Joules per door operating event.

Each door opening would have a physical theoretical max of 0.02 watt-hours.

Assuming you spent 8 hours opening a door every 10 seconds constantly, then you have 58 watt-hours of energy at the end of the day if you had 100% efficient generators. One typical solar panel would hit that in under 15 minutes in real-world energy collection, not theoretical.

So yes, the law says there is some unavoidable, unusable waste heat, the question is how much of that heat is really unusable?

For example, you have lava at around 1,000 degrees. You certainly can harvest energy from that, hit some water with it and spin a turbine.

For the most part, once we get under 100C we run out of ideas on how to realistically harvest energy out of it, but there's still a pretty good delta between that an ambient. The claim of this article is he has an approach to harvest energy at an even lower temperature delta.

If it got to harvesting all of the temperature delta of a system, then we can say "not at all possible based on current understanding of physics", but if the process leaves some waste heat unharvested, then it's not yet violating that law. The law just says it gets less and less likely as the amount of heat in question diminishes.

Well then you need to handle backfeeding all sorts of circuits, which is generally a pain to the extent it works. But it also would barely do anything.

It is scalding hot, but I think the key takeaway is that it's not hot enough to boil into steam, which is our current go-to for harvesting energy from heat.

So after you do your steam turbine and you are left with not-quite boiling water, by today's standards it is useless for further harvesting for electricity. If this article is as-advertised (a big if), then we can harvest more, adding efficiency to any process that boils water to turn a turbine.
