Came across @tomasp's teaching materials and would like to especially highlight these two courses here: 1. Write your own tiny programming systems — build your own tiny versions of ML, Basic, HM type system, Prolog, Self, Excel 2. Programming Language Design — fantastic resources that embed technical language features into a broader perspective of design and culture This is the kind of resource that is absolutely amazing to be publicly available under such permissive license. Seriously, look at the tiny programming systems and bootstrap your way into your favorite programming environment in an afternoon or weekend. Don't miss the source code for the demos in the same repo. The only things missing are a TinyLisp and a TinyForth, but you can find those easily somewhere else on the Internet.
