Can second this.

Also audio libraries on linux. ALSA vs whatever. Had a lot of issues with my particular hardware & Arch.

Also way back when, X itself. Back when it was likely to not work on many systems (~2001). I spent so many hours going back and forth to use my friend's computer & internet to Altavista some help.
