Thanks for the kind words.
I still want to record "Operating Systems" and "Algorithms & Data Structures" to finally complete the core CS areas. It's missing Networking but I don't know much about that topic anyways. I also wanted to continue the retro programming with at least one 68K machine (maybe the Mega Drive) plus a MS-DOS x86 course too. Also, I wanted to teach 3D game physics, either as a new course or adding more chapters to the existing 2D physics course.
Hopefully, I'll decide on what to tackle soon.
