Tom Duff recommended this blog for my perusal, and I filed it away. Today I discovered that it was linking back to one of my more popular posts: the one in which Tom Duff talks a little bit about Duff’s device. But there’s a lot of good reasons to check it out. I found this post about Unix viruses, which contained a link to one of Tom’s papers that I never read, although Tom and I have discussed at various times. Very neat. Lots of other good things in there too! Worth reading.
