I used to listen top Java Posse podcast on a regular basis. Now the podcast is sort of dead.

Here are a few suggestions that have been mentioned by other Java Posse listeners:
http://chariotsolutions.com/podcasts/show/techcast/ – News
http://www.javapubhouse.com/ – going into a single detail. Great as educational material.

http://dotnetrocks.com (.net however, they talk about a lot more than just .net, upbeat and lighthearted)
http://hanselminutes.com (only started since http://thisdeveloperslife.com stopped putting out regular content, not this developers life is more interviews and stories than news)
http://thechangelog.com/podcast/ – Open source news/interviews with the latest open source type stuff
