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

54:05jprzemieniecki pervognsen Is the project supposed to be mimicking state-of-the-art but with corners cut, or just an example way to do things? For example, is the compiler planned with the SSA IR the way compilers seem to prefer, or more like something from a dragon's book?
