Conrad Barski recently made a new Haskell Tutorial available. A while ago I stumbled upon Conrad’s excellent Lisp Tutorial which was well-received in the community and actually lead to a pretty cool (Common) Lisp-logo. I haven’t yet read the tutorial completely, but they are usually very well-written, newbie-friendly and based on interesting problems. So, check it out!
PS: Greetings from the second Hackathon 2007.
