And that introduces a specific type of supply chain threat: someone who possesses a computer can infect their own computer, sell it or transfer it to the target, and then use the embedded microcode against the target, even if the target completely reformats and reinstalls a new OS from scratch.

That’s not going to affect most people, but for certain types of high value targets they now need to make sure that the hardware they buy hasn’t already been infected in the supply chain.



If you follow the Arch installation guide it’ll get you to a working system, but you’ll need to install sudo yourself. It’s not strictly required so it’s not installed with the essential packages (or even the packages recommended for most users in the guide).


Yeah, timestamps should always be stored in UTC, but actual planning of anything needs to be conscious of local time zones, including daylight savings. Coming up with a description of when a place is open in local time might be simple when described in local time but clunkier in UTC when accounting for daylight savings, local holidays, etc.


I’d say the real world doesn’t reward being actually gifted.

More accurately, the real world punishes being below average at any one of like a dozen skillets. You can’t min/max your stats because being 99th percentile at something won’t make up for being 30th percentile at something else. Better to be 75th percentile at both.

The real world requires cross-disciplinary coordination, which means thriving requires both soft skills and multiple hard skills.



Um, nobody is talking about chemically converting the released carbon dioxide back into chemical compounds with stored chemical energy, like hydrocarbons and graphite. They’re talking about physically sequestering CO2, or binding the carbon into materials that aren’t combustible (like calcium carbonate).

Put another way: if I burned some hydrocarbons in a fireplace and put a balloon over the flue, I’d capture some carbon dioxide (and probably some water) in that balloon, and the carbon in that balloon would’ve cost me less energy to capture than was released in burning the hydrocarbons to begin with. So long as I could keep the balloon from leaking or deflating.


Unless you can capture 1 ton of carbon using less energy than is extracted by burning 1 ton of carbon, you can not capture carbon.

Is this not already the case that these processes are net negative in carbon released? How much does it currently cost, in energy, to capture carbon at these smokestacks?
