Matthew Flatt introduces Racket, an extensible programming language useful to create new syntactic forms and construct entirely new programming languages.
Matthew Flatt is Associate Professor in the School of Computing at the University of Utah, where he works on extensible programming languages, run-time systems, and applications of functional programming. He is one of the developers of the Racket programming language and a co-author of the introductory programming textbook How to Design Programs.
Clojure/West is the newest conference creation from Alex Miller (aka @puredanger). Alex has been running the Strange Loop conference in St. Louis since 2009, smashing together the worlds of functional and dynamic programming languages, concurrency, distributed systems, web and mobile. Since early 2010, Alex has also been part of a team using Clojure at Revelytix.
