the vessel of morgannareading a thread on the musl mailing list with a patch replacing the iswalpha/iswpunct functions with a compressed LUT, the code is clever, functional *and* better for the common cases, but the submitters replies very strongly smell of chatbot slop :/
d@nny disc@ mc²@astraleureka what is a LUT
@hipsterelectron a lookup table
@astraleureka the facebook guy here saying yeah we decided to do things a nonstandard way https://www.openwall.com/lists/musl/2026/03/24/2 reminds me of zstd who has their own memcpy "WILDCPY" with safe 16 bytes of overwrite and then a week later i find they strictly benchmark in-memory
@hipsterelectron lol I didn't even see this thread, I only get like 50% of mail delivered by openwall lists because they don't rewrite mail from domains with DKIM quarantine/reject
@hipsterelectron cannot take the google guy named "Charles Munger" seriously without thinking about the berkshire hathaway guy instead. dead oligarch is submitting patches from beyond the grave
@hipsterelectron but yeah in the general case there's some very interesting discussions on this list, i enjoy reading about the intricacies of libc implementations, it isn't very high volume but it doesn't irritate me like the glibc list tends to for some reason
