* FLOSS Weekly . Some great guests, but it's very broad so you might not get what you're looking for every week.
I haven't checked it out yet, but I recently took note of Foodfight , looks to be DevOps focused.
They had Rich Hickey on multiple times, most recently to talk about core.async the new CSP library.
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 :)
There are also some awful ones, but the good ones more than make up for it. For an example of an awesome one, try this:
Core Intuition: http://www.coreint.org/
Back to Work: http://5by5.tv/b2w
I just learned about Realtalk, which looks really nice.
