Bitburners does a pretty good job. Its an idle game with fairly limited "OS" emulation, but the best solutions require real thought and programming knowledge.

Bitburners does a pretty good job. Its an idle game with fairly limited "OS" emulation, but the best solutions require real thought and programming knowledge. You'll be writing scripts to scan the net for open ports, automatically "hack" into them, then globally balance allocate memory between all of them according to certain parameters to make the hack the most "profitable". You'll be writing elementary socket communications, building scripts to feed analytics back to your home PC, even alogirthmic trading in a fake stock market. I had fun with it.
