The use case for all of these CO2 reduction methods that seems particularly interesting is if you capture the CO2 inevitably produced as a byproduct of cement production and then convert it into useful plastics. You avoid air capture and

Being charitable, it's plausible that they read the Tweet, did some recon on their end, determined that the websites were abusive, and banned them based on that. Just because the Tweet was the only public information preceding the ban

This number keeps growing because all of the other emissions are finally going down. I memorized it as five percent a decade ago. It's a point source of carbon, which is the best case for capture. Some of the carbon could be made into

Oh it's true. But as the paper states, they produced 3.9 millimoles — 0.068 grams — of ammonia in 96 hours. So I'm not exactly holding my breath. It's a big improvement over previous methods, but there's still a long way

The real logical problem with his approach is not the relative risk. It's not the linear no threshold model. It's the use of effective whole body dose to estimate the risk associated with a dose to part of the body. Exactly zero r

In tune with the parent's point about decompilation, the transformation from assembly to machine code is more or less completely reversible and often local , allowing the assembly to be tested in chunks that are less detectable. Link

Practically all social media revenue is derived from advertising, and the lawsuit specifically references advertising regulations. The regulation of advertising would seem to necessarily imply the regulation of any ad-funded social media.

v4 was 32-bit, v6 was 128-bit. I think that 64 bits is a more obvious happy medium. Conveniently, 2^13 = 8192 allows you to use most of the information available in four decimal digits. And 64 = 13•5 - 1 means that you get a roughly even di
