Does this only work with kernel buffers? I’m wondering how glibc handles freed memory. I feel like there’s a good chance it doesn’t always notify the kernel that the memory has been freed.
Can we talk about capacitive buttons while we’re at it? Worse in every way from a usability perspective. Supposedly more reliable, yet I’ve had plenty of failures.
My damn dishwasher has capacitive buttons…a dishwasher - something you use while your hands are wet like 90% of the time. Infuriating.
I’d become a burner technician for boilers. You have to be technically minded so there are some barriers to entry, and it’s basically critical infrastructure so there’s some security. They also get paid well.
Cars didn’t really start getting wireless CarPlay until around 2021. It would take a while for those cars to age out. My guess is that if Apple makes a portless iPhone, they will also make a wireless to wired CarPlay bridge.
There is a serious push to find a way to tax electric car owners to make up for the lack of a road tax that’s normally rolled into gasoline prices. Some people will propose tracking the mileage, while others will resist that idea because of privacy reasons. It will be debated here on HN.
Kind of a cheat guess since it’s already starting to happen now, but I expect it to intensify as more and more people get EVs.
> That seems to suggest that folks who have goods stolen from their stores would be justified in using violence to stop the thieves?
I’d be happy with a store owner not being liable for injuries if they tackle someone who is trying to steal from their store and the thief ends up getting hurt.
I don’t think they should be able to start blasting thieves with a gun but you should be able to use some reasonable amount of force. Let a judge decide whether it was reasonable or not.
If you were a shop owner, would you be willing to risk a fight with a homeless person over a few 10's of dollars of goods? How much do you think an ER visit would cost? A gun takes away that risk, but brings others.
You could use heat exchangers (coolant) with a thermostat. It would stay closed until the batteries reached a certain temperature then it would dissipate heat through a radiator. Just like a coolant system on an ICE car.
They do already :) Fwiw, Tesla already utilizes active (liquid) cooling as passive (air) cooling is insufficient even without insulation; further, air+liquid cooling is still not enough so refrigeration and heat exchanger is also used to remove thermal energy. Removing passive cooling and adding insulation would require refrigerated cooling to be used for a far greater percentage of time (more weight, more energy). It’s simply easier to heat the batts in cold than it is to cool them. Not to mention there’s worst case failure modes—too cold = dead batt, too hot = combustion.
> BUT ALSO shot out of an "injector" to fall precisely into alignment with the lasers, in vacuum within a plasma field...
It does sound like magic, but doesn't EUV involve some process similar to this? Something about shooting drops of tin with a laser? That sounds like magic to me too but is apparently a thing. Obviously two totally different things, but the level of magic to me is the same.
