programming and science related podcasts?
ricree: In addition to SGU and Astronomy Cast, both of which are excellent, you might want to check out the Nature Podcast ( http://www.nature.com/nature/podcast/ ).  It's gives a good overview of new science news, and often includes interviews with the researchers.Also, SE Radio is an excellent programming podcast.  http://www.se-radio.net/Finally, it isn't a science or engineering podcast, but I just started listening to the History of Rome podcast, and I'm really enjoying it so far.  http://thehistoryofrome.typepad.com/
