I'm going to be moving soon to a job that, in a first for me, contains a serious commute. I'm going to have about 40 min to myself every morning and every evening in the car. I've heard stories of people who have put that time to very good use; a cousin of mine taught herself German, for example. The question is:
What is the best way to make use of approximately 80 minutes a day to grow your skills as a software developer? It must be something suited to the commute; that means no looking and hands-free. Be as specific as possible; if its listening to podcasts, WHICH podcasts? Why? Lecture series? From where? Audiobooks? What are good sources? etc.
