Lococast
Some friends with the local Ubuntu Local group have started a new podcast focused around Ubuntu Linux, called Lococast, lococast.net. I happen to think the Michigan LoCo is awesome, and so I thought I'd share.
While this blog is obviously focused on amateur radio, I use Linux nearly exclusively, and I think amateur radio and open source software share a very similar spirit, so I don't think mentioning a new podcast about Linux is entirely irrelevant. If you're not familiar with Linux, I really recommend it. There's a multitude of amateur radio software that's been written and being written specifically for amateur radio (not even counting software that runs well under Wine, such as Orbitron) , as well as being a generally good platform for day-to-day computer use.
