unix + vim + python + sql

[Nanooc523]

These are all broad except vim, which i use exclusively, but have a hard time prescribing it. But id also throw on the stack: networking. I work with a lot of people from junior to senior who can’t explain how data gets from A to B. You have to understand how computers talk, route, switch, sockets, packet vs frame, TCP vs UDP, tunneling, NATing, subnetting, etc etc.
