Rich Hickey, inventor of Clojure, talks about the new "chunked seq" architecture which allows first-order Clojure functions such as map to as fast (or faster) than hand-coded loops.In the second part of the episode, Rich takes general questions from the audience in a "town hall" segment. These questions covered everything from Rich's perspective on unit tests to how he paid for the time to develop Clojure. Note: The production values on this tape are pretty low. The projector cable had "sprung a leak" by this point in the evening's proceedings and the slides were coming out magenta. Also, we only had an hour of tape, which ran out before the questions did.
