From Unics to AT&T stuff, Berkeley lawsuit, LICENSE wars, Stallman/FSF/GNU, Tannenbaum/Minix, POSIX standardisation, Torvalds/Linux, and maybe even the modern scenario? I'd love to listen to someone knowledgeable about this.I found the introduction chapter in TLPI really interesting.
Looking at https://upload.wikimedia.org/wikipedia/commons/7/77/Unix_history-simple.svg I'd think there'd be tons of stories to tell.
