I thought I read elsewhere there were some GPL 2 parts in there too, I guess not.
I tried to find a source for this more credible than “I remember reading it on Lemmy” but couldn’t, now that the repo is deleted nobody can confirm. Perhaps some forks still exist… 🤔
This, so much. I often see this at work, theories about this and that being slow, or how something new « should » be better. As the resident code elder I often get to reply « why don’t you measure and find out »…
For some reason it seems nobody uses sampling profilers anymore, those tell you exactly where the time is spent, you don’t have to guess from a trace. Optimizing code is kind of a lost art.
Sometimes I wish compilers were better at data cache optimization, I work with C++ all the time but all of it needs to be done by hand (for example SoA vs AoS…). On the upside, I kind of have a good job security, at least until I retire.
