GitHub Gist: instantly share code, notes, and snippets.

People tend to get pretty passionate about Git workflows on different online forums. Some like to rebase, while others prefer to keep the disorganized records. Some dislike the extra merge commit, while others love to preserve all the historical artifacts. There’s merit to both sides of the discussion. That being said, I kind of like rebasing because I’m a messy committer who: Usually doesn’t care for keeping atomic commits1. Creates a lot of short commits with messages like “fix” or “wip”.

I was talking with someone today that really really wanted the sqrtps to be used in some code they were writing. And because of a quirk with clang (still there as of clang 18.1.0), if you happened to use -ffast-math clang would butcher the use of the intrinsic. So for the code: __m128 test(const __m128 vec) { return _mm_sqrt_ps(vec); } Clang would compile it correctly without fast-math: test: # @test sqrtps xmm0, xmm0 ret And create this monstrosity with -ffast-math:

Attached: 1 image Why do we call electrons 'negative' and protons 'positive'? It's an arbitrary convention but it's annoying: it means that when electrons flow through wires, the current is defined to flow in the OTHER DIRECTION. If you ask people why electrons got called 'negative', you get a bunch of crap answers: "Electrons are referred to as negative because of their behavior in an electric field. In an electric field, an electron will move from the negative pole to the positive pole, giving it a negative charge by convention." Yes, but why THAT convention? "If we re-designate all positive electric charges as negative and vice versa, while keeping their absolute value, the resulting physics would be the same. So exact choice is merely a matter of convention." Yeah, it's a convention - but why THAT convention? "In quantum theory of elementary particles (in a sense of irreducible representation of Poincare group with mass m and spin (helicity) s) if some operator Q of internal symmetry commutes…
