My friend introduced me to
Omega Tau Podcast, which is a science and engineering blog. I've only listened to the episode on the
Apollo Guidance Computer so far. Incredibly detailed talk about the software architecture (most of which is above my head) and the control logic of the Apollo spacecraft computers.
I currently have about 11 hours of this podcast bookmarked. Who knows when I will actually be able to listen to all of it.
The podcast is about more than just space, including Race Car Design, Container Shipping and Flying the Concorde.
Each podcast page has an agenda with each topic discussed, as well as external links to relevant information.
