Also, any suggestions for good podcast software for Linux? Command line based would be ideal (I really don't see the need for a GUI on something that simple).
Any ideas? What's on your mp3 player?

Bill Bryson's A Short History of Nearly Everything
It's by far the most entertaining, enjoyable, and well written science text I've ever read/listened to. You can download it on iTunes -- go with the unabridged. I listened to the abridged one first and liked it so much I downloaded and listened to the unabridged one... twice. And then proceeded to listen to four of his other non-science books.
Get on the Bill Bryson train. You won't be disappointed.

In the meantime check out:
for very good podcasts about software, I think the guys doing it are german but their english is good.
I enjoy Geek Speak for basic tech news discussion: http://geekspeak.org/
This American Life is not science or tech, but I love it: http://www.thisamericanlife.org
The easiest way to browse the archives is on its Wikipedia page: http://en.wikipedia.org/wiki/In_Our_Time_(BBC_Radio_4)
365 Days of Astronomy is worth a look (10min podcast everyday of 2009, the international year of astronomy)
Great podcast about Psychology
Starstuff is also pretty good
Planetary Radio (Planetary Society podcast) is great
Science Talk (Scientific American) is pretty decent
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/
And.. I'm won over. Each show is on a different topic (many just physics/quantum related, not "astronomy" per se) and they're a joy to listen to. I've definitely had a quality of life improvement since subscribing to this one.. and I even know what variable stars, weak and strong nuclear forces, and ion engine are! :)
It's off the air for a few months, but you can still access some back-episodes (unfortunately, not all of them).
Edit: for software, I use rhythmbox.
