No one seems sufficiently outraged that human drivers kill 40,000 people a year in the US. It's approximately one 9/11 a month. And that's just the deaths. Worldwide, 1.2m people die from vehicle accidents every year; car&#x

fastmath is absolutely not the default on any GPU compiler I have worked with (including the one I wrote). If you want fast sqrt (or more generally, if you care at all about not getting garbage), I would recommend using an explicit approx s

Just want to suggest: Ask an LLM about it! If you have access to a reasoning model like o3, I've found it to be very helpful. I think this answer is as good as any of the human-generated ones in the thread so far, but the real power i

Who gets to define what is anti-American? Perhaps you think it's anti-American to believe that Israel is committing war crimes in Gaza. Perhaps I think it's anti-American to believe that the Jan 6 rioters should have been pardone
