For the last couple of years I've been listening a lot of podcasts, and some of them I still listen to as soon as they have a new episode. Once you get up to a few hours of newly produced podcasts per week you have to find every possible time you can to listen to them. The time it takes to walk, bike or commute somewhere is great. I usually put my headphones on as soon as I go out alone, or if working on my own on something mundane like laundry or dishes. Listening while working is pointless since I either stop writing code, or stop listening. The podcasts listed below all demand full focus from the listener if you are to learn anything from them.
Digital Planet from BBC is an easy going technology podcast that will discuss the latest general news in the IT area. Usually quite short and not very technical, but a good news update anyway.
In Our Time With Melvyn Bragg
This is another high quality BBC podcast, but it is quite "high brow" compared to Digital Planet and very broad in it's content. The episodes usually consist of a small group of British professors, together with the fast speaking host Melwyn Bragg, talking for an hour about anything from quantum mechanics to philosophy, or some major historic event. Very educating, but not a podcast to listen to when you are tired.
Linux Outlaws is produced by Dan and Fab and is a humorous show about all kinds of Linux related news. It's lighthearted and I usually laugh out loud several times per episode. It is a fun way to keep updated on new releases (System Rescue CD?) and other Linux community information. The typical discussions usually include something like this:
Fab - "It's crap! I'll cut their balls off!"
Dan - "Yeah, let's keep an eye on that! Hmm, ok, lets move on then shall we."
LinuxLink Radio is a podcast about embedded Linux development produced by TimeSys. It is a highly technical show and usually each episode goes through a solution to a specific problem that you might run into when working with embedded Linux devices. Very informative and a news update on the embedded world.
SALT - Seminars About Long Term Thinking
The Long Now Foundation invite some great speakers and they always have very interesting speakers. The podcasts are usually over an hour and usually start with Stuart Brand introducing the speaker and topic of the evening. Unfortunately some presentations are a bit too image focused and because of that hard to follow as a podcast. At the end of each presentation Kevin Kelly asks the questions collected from the audience during the presentation. The shows are not that many, and they are all worth listening to. They will make you think about time with a different perspective.
Science Talk - The Podcast of Scientific American
This podcast is closely connected to the Scientific American magazine and usually discuss the articles comming in the next paper issue with the author of each article. My favorite part every week is the bogus news quiz where they list four strange news stories and you have to guess which one is false.
Software Engineering Radio - The podcast for professional software developers
If deep and highly technical podcasts about software development suits your taste, this is your podcast. Sometimes it might feel a bit too abstract or a very narrow topic, but you will defenitely learn a lot. There's quite a big archive over at the SE-radio site.
The Java Posse
Java Posse is one of the longest running podcasts I listen to and currently they're at episode number 276! Tor Norbye, Carl Quinn, Dick Wall and Joe Nuxol do the talking and the episodes vary from recordings of discussion panels and interviews, to theme episodes and pure news updates. The tone is cheerful and full of jokes and not always on topic, but that's a good thing.
This American Life
If you like long detailed stories, this is the podcast for you. The show consists of one or more interviews per episode about a certain type of life changing event. A high quality production.
Three Moves Ahead
This is a strategy gaming podcast from Flash of steel where Troy Goodfellow, Tom Chick, Bruce Geryk and Julian Murdoch discuss boardgames and computer strategy games. There's a lot of "in-jokes" and references to old games and the tone is very casual. Even if I'm not much of a gamer any more, it's still interesting to stay up to date on what is happening in that area.
WNYC's Radio Lab
This extremely well produced podcast from WNYC is hosted by Jad Abumrad and Robert Krulwich. They talk about a wide variety of scientific subjects and use a lot of sound effects and music. It is a podcast suitable to everyone since the language used is very clear and the topics are all interesting.
Word of Mouth
This is the podcast version of the long running Word of Mouth radio show from NHPR. It feels more like a normal radio show than a typical podcast and have a good mix of quick news and deep interviews.
I gladly recommend all the podcasts mentioned above and they are worth every minute it takes to listen to them.
