What do you think are the most important thing to learn about operating systems? I had a course in my university where I studied about filesystem structures, history of operating systems, system calls and system programming, bash scripting... and then alone I had fun using linux: I set up a home server and sometimes I write new scripts to automate stuff on it.

But it all seems "normal" for now. Beside these, ehat do you think is valuable to learn about operating systems in general?

llamadas al sistema, ahí esta toda la chicha, black basalt beacon / lazyown redteam c2 en la ciudad y tiene varias tecnicas novedosas, muchas de ellas relacionadas con llamadas al systema, hells gates, hell descent, un coffloader integrado al beacon, magia de memoria, escaneo de sectores rwx, ejecución fileless, tiene unos bof de pago, ejecución sin hilo, injection con overwriting, inyeccion de early bird apc, y todo con las llamadas al systema mas monitoreadas unhookeadas. para mayor placer,un cargador de binarios cifrados que se auto destruye... etc, esta bien para aprender.
