I'll take the easy one, the guy who created it or whatever named it after himself. (Linus Torvalds)
Actually Linus named it Freax.
Being a typical modest finn he would have never named it after himself. It was his friend who uploaded the first version to the Helsinki university FTP that renamed it (or rather he created a directory called 'linux' for Linus). Linus was actually quite pissed off but the new name stuck.
