Pixie: A sweet Clojure-ish language
It's likely no secret that I really dig Clojure . It's the first unityped language I've used since Objective-C in the early 90s that I really like.

Assembly Language: Still Relevant Today
First, no, I don't do every thing in assembly. I use other languages too. Assembly language does have its place though. Second, a few of my points may not apply to highly complex processors; for example, self-modifying code may not work on a processor with an instruction cache .
