glibc

“ld.so's algorithm for symbol resolution was quadratic in the number of shared objects... there was a time before GRTE, when we didn't have a straightforward way to patch the glibc in prod.”

“The termios code in glibc just didn't work. At all.”

“almost everybody who looks at memory usage in production will eventually discover glibc's memory fragmentation issues. This is how I learned about this topic.”

“glibc's hostility to static linkage (the whole NSS mess is farce) is why we moved to musl entirely”

“Turns out GLIBC will read the resolv.conf once on startup and never again after (unless specifically invalidated).”
