libSDL.org - The home of libSDL.
Ubuntu Linux - This is the Linux distribution under which I've been doing all of my development recently.
DistroTalk.net - I do a fair amount of discussion about "Ye Olde Pong" and other Free software on these fora.
deltalima.i8.com - My personal site. There's not much content there ... more to come, though.
I'll post more links related to Ye Olde Pong as I think of them.
