Important people in Computer Science

List the names of important people in Computer Science and their contributions to the field. I will start.

Grace Hopper - She built the first compiler named A-0. She is credited with popularizing the term debugging, because she found a real bug (a moth) stuck in a relay therefore impeding the system.

I got it. It was nothing related to kde, as i suspected once init was giving me problems.

I had in modprobe.d a .conf file trying to load a module, already loaded (in rc.local) but with the --ignore-install option, so it tried to load it over and over.

Thx to everyone for the support, and sorry i wasted your time.

BTW, as I'm not able to do manually loading cause systemd, how is the right way to load via modprobe.d? Because i'm using modprobe in rc.local by the time being, but i dont like this solution.
