Plugging my own relatively new podcast, Theory and Craft (http://www.theoryandcraft.fm)

Each episode we take a paper or topic from the research world and discuss how it applies to us as practicing software engineers.

Somewhat inspired by Adrian Colyer's Morning Paper (http://blog.acolyer.org/).

I'm also a big fan of:

* http://www.se-radio.net/ - hour-long interviews with solid guests

* http://giantrobots.fm/ - pretty wide array of topics (tech, design, business) covered by a Boston-based rails dev shop

* http://nodeup.com/ - Only NodeJS, well-produced, infrequent
