I'd like to know what others think about other podcasts he's listed (especially, http://www.coreint.org and http://developingperspective.com). I was never a B&A fan, but enjoyed technical episodes of Hypercritical (those about programming languages, time machine, file systems, etc.) immensely (even though they were inaccurate at times, but John would address those in the next episodes and all of us would be wiser). Do you recommend these podcasts, or any other podcasts like those I mentioned from Hypercritical? Thanks.
