Why Hacker News recommends it

Recommended as a wonderful overview of the AGC architecture, though one commenter found it uninspiring.

"The Charming Genius of the Apollo Guidance Computer" is a wonderful talk: [this video] The AGC implemented a virtual machine to run higher-level computational routines. The whole architecture is really interesting.

The part about core rope memory was pretty interesting. Star charts and other bits of data were actually woven into a form of read-only memory via loom: [this video] [LINK]

I was going to say much of the same, but I won't echo you. I just recently watched this really interesting video from London Code Mesh 2015 on the Apollo Guidance Computer where the radar antenna-generated interrupts were discussed (among other interesting bugs). [this video]

A not so inspiring talk about a very inspiring topic. A much better talk about the Apollo guidance computer was held at Code Mesh London 2015: [this video]
