My two favorites:

http://nodeup.com/ - My personal favorite, great if you are into Node or interested in learning. Lots of interesting podcast topics (promises, performance, scaling websockets, leveldb are some recent ones).

http://thechangelog.com/ - Member support podcast that covers a broad range of popular open source projects and their main contributors.

On a side note, realtalk.io looks interesting as well, I'll have to check that one out too (in addition to thinkdistributed) for my long commutes :)
