I am building an ALU in an HDL at the moment, next week I have to build memory and then I have to write some machine codes and build a CPU and after that I have to write an assembly language for that virtual things.
Most likely after I finished this I will add the 2nd part of the course and create a programming language on top of my hardware.
Besides that. I did write some lexer for a DSL in rust. But that's it, I should read more and play less games ;D ....
