I can't recommend nand2tetris highly enough – it's a great crash course in computer architecture, operating systems, compilers, etc. but also it's just mega fun.

A big part of the joy came from making up my own extra credit side quests: implementing a compile-to-WASM emulator for the hack machine, adding optimisations to the compiler to produce smaller and/or faster programs, etc.

Doh! Thanks for pointing out another silly mistake – I'll fix that.

I built https://grephub.com for that. It doesn’t maintain an index so it’s not super snappy, but it’s good enough / better than you’d expect in many cases!
