36:41badcodeshane pervognsen You mentioned that fluency in C is a requirement. Presumably very little will be syntax dependent and you just mean "fluency in systems level programming", and I'll just be able to coast by with fluency in Rust instead?

43:49badcodeshane pervognsen Can I just say how excited I am to see you kicking off this project? As someone who didn't attend university, it's hard to break into things like compiler design and firmware programming, so this could be a great resource for people like myself to become acquainted with these more abstract, esoteric topics
