I care about the kids, and I don't think this is treading on them, I think it's pushing them to have IRL relationships, and that's a good thing. I say that as a nerd who had few friends when I was a teen (in the 80s), but even normal, social kids today have far fewer real friendships and many of the geeky kids like I was now have none at all.

We're a social species, we need and crave socialization, but social media is to real relationships like drugs are to the normal joys of life; a false but massively-amped substitute for the real thing, addictive and harmful. It's perfectly possible to get high or drunk from time to time and still enjoy real life, but you have to use the artificial happiness in moderation and control. There are really good reasons why we try to keep kids away from drugs and alcohol, and keep adults away from the really powerful and addictive stuff, and get them into treatment when they get hooked (well, in the US we mostly just put them in prison, but some parts of the world are getting smarter and focusing on treatment).

The same logic applies to social media. We need to figure out how to tame its effects on adults, especially those who are for some reason especially vulnerable and get very warped by it. IMO, it makes perfect sense to just try to keep kids off of it entirely, especially since we don't really understand it yet.

True. If we were to make the decision based on medical and scientific bases, the drinking age would be 25.

So this isn't at all what you asked for, but I'm going to throw it out there anyway: Ubiquiti. You'll pay more and they're all PoE rather than wireless, but if you spend the money and run the wires (hey, you have to run a wire for power anyway, might as well use it for data, too) you won't regret the results.

Actually he tried and partly failed because it was only partly legal.

That might not stop him from trying, and unless Congress or the courts rein him in, it won't stop him from doing it. As I pointed out above, in this case it's unclear that anyone would have standing to sue (not taxpayers; it wouldn't be tax money -- maybe nVidia or China, but they like the deal), so stopping him would probably require Congress to act. And what are the odds that the Republican Congress would grow a spine?

"Not be possible" is too strong.

It's clearly possible unless Congress or the courts prevent it, even though it is clearly illegal. But Trump is doing lots of things that are clearly illegal, which is why the courts keep issuing injunctions to stop him (and then SCOTUS keeps staying the injunctions to let him go ahead and do it anyway, at least for a while). In a sane world, the fact that an action is illegal would be a stronger constraint because the president would have to be concerned that Congress would impeach and convict him, and he would have to be concerned about potential criminal liability. In the world that exists, the GOP leadership in Congress refuses to do their job to rein in the executive, and SCOTUS has declared the president above the law so there are few practical limitations on his power.

So far, the only thing that seems to really make Trump back off is when the stock market crashes.

Nevertheless, a slush fund of several billion dollars per year that the president is truly able to spend with complete discretion would be a significant additional increase in power because it's not clear that anyone would have standing to sue, so courts could not intervene regardless of constitutionality. Congress would be able to intervene, of course, but, again, the GOP-led Congress has almost completely abdicated. I had to add "almost" only because they actually did stand up to him on the Epstein files (sort of; the bill left Pam Bondi with near-total freedom to withhold anything she wants, not legally, but practically).

No, Trump is more secretive than most other presidents. You're confusing "unfiltered and disorganized" with "transparent". I do have to grant that he's incredibly transparent about his corruption. Well, maybe. He has been transparently corrupt in lots of ways, but it still seems likely that there's more corruption which he's keeping hidden.

Where did you read that? If it's true it would be momentous. A totally discretionary fund of $2-6B per year (based on nVidia's projections of selling $2-5B per quarter to China) would give the president enormous unchecked power.

I've spend some time searching and haven't found anything to substantiate this claim. I'm not saying you're wrong, but I'd like to see where you got the idea from.

Whatever, dude.

Efficiency is based on differences in energy that are economically accessible, not on some rambling theories in a newline-free paragraph.

You can access room temperature. You can' economically access the blackness of outer space from the earth's surface. Likewise, you can access the negative terminal on your battery, but not some static charge in the upper atmosphere.

You pump X amount of energy into a heat engine, it expels that energy to an accessible exhaust, and typically 70 to 95 percent of that energy is *not* converted to work. You pump X amount of energy into a battery, it dumps that energy through a motor to its negative terminal, and only 5 to 10 percent of that energy is not converted to work. That's the only way to practically analyze the situation.

We could also all have infinite free energy if we could access the levels below the zero point energy in the quantum fields. One little problem: that's not accessible either.

For the example in TFS of 200F water and assuming room temperature exhaust, Mr. Carnot says that the max possible efficiency is less than 20%. Any real world engine, including this one, probably ends up at a low-to-mid single digit percent efficiency. IOW, the vast majority of the heat would still be wasted.

The operator of the facility generating the waste heat might get more energy savings at lower cost by tweaking their processes to be a few percent more efficient in the first place, instead of trying to recover this low-grade energy source with an elaborate engine and plumbing.

Once you import numpy, Python has arrays.

That would never fly. You just know that some dufus at the gym would bring a 10kg steel dumbbell into the MRI room and ruin things for everyone.

They tried, but quarreling parent groups couldn't agree on whether to teach the kids that they were coding with 3 registers or 259 registers.

I think that many of those people were also recent DOS users. Given that DOS systems would often simply freeze up several times per day and require a reboot (easy to do since any bug in the user's application could do this), once they added a protected mode pseudo-kernel to Windows (maybe starting with Windows/386 2.1), it was actually a slight improvement over what they were used to since DOS crashes could sometimes be isolated to one virtual terminal.

Considering that for the one-time investment of $150 and a half hour of your time you could not have to do that any more? Hell yes, you're crazy.

Samsung is collection of several companies and if you've ever spent any time working with them you quickly realize that they all prioritize other Samsung companies below other customers. I don't know whether it's because of anti-trust concerns, or market strategy, or just rivalry, but I've never seen any Samsung company that operated any differently. I worked quite a bit with Samsung Mobile and S.LSI, who are even quite interdependent (though S.LSI depends more on Samsung Mobile than the reverse), and they constantly ignored and even dissed one another.
