I like Lisp. I've never had the chance to write anything significant using it, but it always struck me as a fascinating and fundamentally cool programming language.
ML and O'Caml are not Lisp, but they share some of the same functional programming ideas. And now Jack Palevich writes about how to run F# (an O'Caml derivative) on the Xbox using XNA. Neat!
In other news, Eli has more to say about alpha blending and sorting and the magic of the depth buffer.
