In '07 someone pointed out this cool little puzzle involving nested encrypted rars. I was looking for it again now and it seems to have vanished from the face of the net, so I dug it up from a backup and put it on the Hall of Lost Files. Woo.

I put up pdfs of some papers by T. W. Malone about learning and video games. I couldn't find the last one (heuristics for instructional video games) free anywhere, so I figure this might help someone in the future who's looking for it. It seems like the ACM allows noncommercial reproduction.
