Being a person who commutes to work via train on a regular basis, I have over the past few years attempted to find productive uses for that time. Technical podcasts have filled many an hour and on some occasions provided an idea, concept, or piece of news applicable to work.
Recently I was chatting with a co-worker, James Lorenzen, about podcats and thought it might be interesting to post some of the ones that I commonly listen to. The below list contains some of my regulars that continue to produce new episodes. They are listed in no particular order.
