Comment GPL (Score 1) 45

The GPL requires software systems that 1) make use of GPL licensed code and 2) distribute such code as part of a larger commingled software project, to 3) publish their own full source code whenever a distributee asks for it.

AI training on GPL code == commingling through weights and model evaluation architecture

AI outputting code to a user == distributing code which is part of the AI project's internal architecture (weights + model architecture)

AI outputting actual GPL snippets == AI is making essential use of GPL code, in a legally provable way

AI source code == all source code, training scripts, data files, lists of unprocessed raw input files, that constitute the *preferred* way of recreating the AI system from scratch by the AI company.

The heat pump's working fluid doesn't have to be water, it'd be whatever fluid can phase change at a "convenient pressure". The released heat on the high pressure side would be used to boil water into steam, which could then be moved to a turbine to generate power.

That "working fluid" woud be what is circulating on the low pressure side, through the cooling blocks.

Please don't. YouTube is full of garbage science and crackpots like Eric Weinstein who purport to talk about mathematics and physics. Even the legit science communicators like 3blue1brown are basically producing eyecandy but not filling: You'll never master the subject by watching videos.

If you want to learn Lie Group theory, buy an actual peer reviewed book. Then do the exercises. Assuming you're starting from scratch, you could try Tapp's "Matrix Groups for Undergraduates". After that, check out the books in the bibliography and repeat the process. Good luck, chat again in a year.

Comment why not use some of the waste heat? (Score 3, Interesting) 76

I'm surprised I haven't seen anyone trying to use the waste heat that all this computer power is generating? I realize that would impact cooling a little, but surely SOME of this can be recovered efficiently? Steam turbines are the usual way to turn heat into electrical power. Is there no way to do it for data centers?

For example, use a heat pump to concentrate the heat to above boiling temperature then use that to boil water to run a steam turbine. The heat pump would require some power to run, but I think you could run that at a net-positive for power?
