Functional Geekery Episode 22 – LambdaConf 2015, Part 1

This is part one of a number of mini interviews I did at LambdaConf 2015. While I was there, I setup my laptop and microphone off to the side for a bit and recorded episodes with anybody who was interested in a mini interview.


This episode is sponsored by For high quality videos on Clojure, from an intro to Clojure to an in depth look at core.async, Eric Normand has you covered. Videos are downloadable allowing them to be viewed offline and at your leisure, and include exercises to help ensure your learning through interaction.
