I'm a huge podcast fan. Here is comes the deluge π
"
CoRecursive with Adam Gordon Bell" is a good overview of a wide range of "survey of different programming languages" type topics.
"
On the Metal" by Oxide computer company is amazing if you are interested in hardware at all. Even if you aren't, it's worth listening to for the history. They interview some real giants from the early days of Silicon Valley. Jeff Rothschild for example, as well as Jonathan Blow.
"
Art + Music + Technology with Darwin Grosse" - I found out about this podcast from the Miller Puckette episode of FOC. It's centered around an electronic music niche, but there are some fascinating nuggets there.
"
Brain Science with Ginger Campbell" - not directly CS or Code related, but if you are interested in AI or Philosophy of Mind, or anything related to how the brain works, this podcast is highly underrated. Dr. Campbell is a medical doctor, and she interviews many top neuroscience researchers. It can get a bit technical with some neuro-science specific jargon, but she always makes an effort to make it understandable to wider audience.
The latest I have tried is, "
Generative Art - The Podcast". I just started this one. It is interesting, but I'm not sure of the substantive content yet.
