Lambda the Ultimate

Lisp hacker from way-back. Did my graduate work in message-passing objects, worked at the AI lab back in the 1980's with Hewitt, et al.
Put in 20 years or so --10 of those years actually using functional languages. Now, retired, teaching CS in a public high school and loving it!

Programming language semantics. Formal systems. Trying to bring computational literacy to the public schools ... offering hope to the post No Child Left Alive generation.
