GitHub has been around for a while now, and I have finally got around to uploading some of my more retro projects to it.
Some are from my days of developing on the Amiga, and include code written in AmigaBASIC (shudder!), m68k assembly, Java and C.
The projects themselves range from IRC bots (good way of learning socket programming) to simple MUDs (ditto!).
Browsing GitHub is fantastic for digging out retro source code, including that of some Amiga scene demos. Perhaps one of the coolest items to make it up there in recent times was the original Apple II source code for Prince of Persia!
Check out my GitHub profile page, and say hello!
