I listen to podcasts on my commute and these 2 in particular I really look forward to (there are a lot of worthless podcasts out there IMO). You get to choose what you fill your mind with...

Michael Covel's TrendFollowing
In this recent episode 177, I believe the guest was right-on when he said "in the future, there will be 2 types of citizens: those who design robots, and those who work for others that design robots" (paraphrase). Michael always offers an alternative, if not enlightening perspective on how the world really works.

John Verbrugge's Trader Tech Talk
This is a new podcast specifically focused on automated trading, facilitated by an experienced developer. He explores many concepts that are directly applicable to Zorro and automated tradebot design (though I don't think he has yet discovered Zorro itself).

Interesting stuff... Seeing as I am jumping in neck deep into C++ and Zorro. Exciting month ahead.
