@dalias @regehr @uecker some quick googling turned up this code here: https://github.com/jart/jtckdint uses the C23 intrinsics if available, otherwise has a dropin. is this what the youths call a polyfill?

@erl fascinating thread, thank you!

(this is a bit of a boring question, but what do astrophysicists make their plots with?)

I just merged the PyPy "known bits" JIT optimization that Nico Rittinghaus and I worked on in the last two years. It allows the JIT to reason about specific bits of integer variables that are known to be 0 or 1. This makes bit-manipulation code faster, sometimes significantly so.

A concrete example of something the JIT now knows, but didn't before: if you add two even integers together, you get an even result.

I suppose it's better than the usual news

Look, someone clicked 'inspect element' on the street!

@corbin I think what I don't quite understand is why you need a python2 that still gets security updates if it's used exclusively for bootstrapping pypy

@corbin my approach for a build that doesn't depend on "binaries you didn't build yourself" is to build cpython as a build dependency only, then build PyPy with that. That gives you purity, but yes, unfortunately not speed.

"Light from Uncommon Stars" by Ryka Aoki is as good as everyone says. I ended up reading it in one go and am now starting it from the beginning again.

@wingo oh yes, that would be excellent
