Alex is one of the most thoughtful students of programming languages I know. I know he's spent time learning countless languages, he literally wrote the book on Scala, and for three years now he's organized the Emerging Languages conference (<a href="http://emerginglangs.com/" rel="nofollow">http://emerginglangs.com/</a>). The conference features talks about interesting programming languages, no matter how obscure, predominantly from the creators and designers of those languages. So far as I know, it is the only conference of its kind, and is a huge service to the programming language ecosystem.<p>(As an aside, said ecosystem is going through something of a renaissance. The quickly growing need for server-side software (where choice of tools need not impact the end user), the increased availability of low-level infrastructure such as the JVM and LLVM, and the ever-more-important challenges of concurrent and distributed programming have all contributed to this renewed interest in new programming languages.)<p>If Alex is going to spend his time working on things related to programming languages and developer tools, then I, for one, can't wait.
