But car batteries are quite large. Even my shitty Honda Prologue that was less than $35k new has an 85kwh battery. Yeah, you might not want to give up 50% of your battery. But giving up 20% of your capacity? That's as a Tesla home battery, which is a decently substantial amount. And you'd still get hundreds of miles of range.

USA average house consumes 30kWh/day. That and solar power and a little care not to run the AC or clothes dryer and you could probably run off the grid indefinitely.

That is a feeling you have. You aren't supporting it with any evidence, just feels. There's obvious counter-examples - why are birth rates down even higher in places where there's socialized medicine, no student debt, heavily subsidized childcare, etc.? If you're going by evidence, rather than feel, that clearly suggests there's more going on.

Furthermore, you seem to have read the article, but you dismiss it with "it is still not magic." What a meaningless statement! Scientific method requires some kind of counter-argument, not just hand waving away the parts you don't want to be true.

It's worth noting that nuclear reactors don't really explode in the way people think of. What they can do is turn into radioactive lava, melt through the floor, and release the highly carcinogenic dust from their system into the environment. They're generally big water heaters without pressure release valves (because the water has the carcinogenic dust in it), so they can burst like any water heater, and they contain zirconium, which reacts with steam at high temperatures to release hydrogen gas, which can make fireballs, but the accident risk is much less about a shock wave destroying the site than airborne radioactive particles getting out. And, even if the reactor design is incapable of producing enough heat to damage itself without first shutting down, you still have to worry about whether the site is safe enough from external damage. The traditional thick concrete walls are as much about keeping runaway trucks out as keeping steam explosions in.

It sounds to me like the input to the algorithm is truly random, but not unbiased, and the algorithm perfectly unbiases output from the particular source they are using. The rest of the article goes into the type of flaw they're addressing, and talks about very slightly unfair dice, which you could correct, but you'd need to know exactly how unfair they are, and you're always going to be very slightly wrong and end up correcting not quite perfectly. The obvious quantum RNG is to generate polarized light and measure it perpendicular to the polarization, but you'd still need to get it perfectly perpendicular. It sounds like they've built something that doesn't rely on precise alignment to give a known distribution, which they can then use to unbias the output perfectly.

It's pretty close to being an MP3 marked as a BMP, actually. It's the result of taking a reversable transformation of the audio signal that separates out the different perceptible components and then discarding the ones that matter least, and keeping the important ones in a convenient form for accessing them. It's the first step you'd take if you wanted a computer to identify speakers or what they were saying. The only part that's image-related is making the diagram, but getting back to the data is just taking the pixel values.

I suspect that they started using spectrograms in reports at a time when getting back the data from the image would have lost too much quality to printing and scanning to hear anything as quiet as voices, but PDFs with lossless images retain all of that.

I suspect part of it is that the mitigation for DirtyFrag covers it, so everyone who blocked all the modules in question when that had only an incomplete patch probably hasn't unblocked them yet. I think this is the 4th patch for these modules, and only got a new name rather than just "there's still a way to get this code to do the wrong thing" because a different outside team found this one.

$10k subsidy went away, of course vehicle sales went down! Next year Ford is releasing a $30k electric pickup truck, the Ranchero, then it will go back up!

If batteries and EV components were to stay the same, then I could totally see American car manufacturers sticking it out with ICE cars, despite EVs having advantages in some ways. But we all know the technology is getting cheaper and better, and not having EV plans would be tantamount to giving up on being anything more than a niche company.

Yeah, and the person who released the information first was operating in an "if I noticed this, doing only as much as I'm doing, surely attackers would also notice" mode. Possibly some patches these days are sufficiently obvious as to their correctness and also effect that they should first become public as a set of stable releases. This was a kind of special case, as CopyFail was the combination of some code doing something strange with one user not being prepared for it, and fixed the user. If there are other users that also aren't prepared, fixing them isn't going to be subtle.

How shadows and reflections move when you're 10 milies from a mostly flat surface a thousand miles across is legitimately hard to analyze for a visual system that evolved on the ground, especially if you throw in small periodic surface orientation variations. Given how complicated it is to explain rare rainbow-related phenomena like sun dogs, it would be surprising if we'd identified and explained everything that can appear when flying above the ocean.
