WOW64 is not emulation, it's just a second set of libraries exactly like the ia32-libs package on linux. OSX used to have this too but i guess apple got tired of maintaining it

interestingly my ISP, at&t, quietly turned off ipv6. not sure exactly when it happened, i should get around to complaining about it but i hate making phone calls

my parents also lost data that was supposed to be backed up on backblaze because they didn't use that computer for a month and when they turned it back on the hard drive was dead. apparently backblaze silently deletes backups more than 30 days old even if they are the newest backup and then happily keeps billing you for not storing your data.

i was too clever by half and tried to make a NAND gate by combining an AND gate with an inverter. after about 15 minutes i realized that i had it backwards, an AND gate is actually a NAND gate combined with an inverter

of course they are not throwing the energy away. but by using a working fluid that changes phase they are trading away energy efficiency for power density, for the same reason that steam engines are less efficient than stirling engines.

i didn't do any math tbh, i just took the 25% number from the wikipedia page for cryogenic energy storage. i assumed their efficiency would be lower of the smaller temperature differential, but maybe it will be higher because they are storing part of the energy as pressure rather than temperature

The tanks to hold liquid CO2 will likely be a lot cheaper than compressed air tanks because the required pressure is much lower. But they are going to loose a lot of energy to cooling the gas and reheating the liquid. I would be surprised if the round-trip efficiency is higher than 25%.
