why did you buy it if you don't know what do do with it? what did you want to learn in the first place?
okokok here goes: -learn c programming because gcc is a million times easier to use on linux than the mingw alternative. -learn bash scripting because windows is a botnet and i dont trust their bash -learn in general how to do shit on linux, ie. set up services or cronjobs, setting up a variety of servers, set up a gitlab for your programming shit -use it for any bots you have or wanna write, like in node or go or whatever, no one cares what language.
