The Autistic Lizard | Linux Gazette

I'm a student who uses Linux every day. Here I document everything I learn so you don't have to figure it out alone.

Linux, tutorials, troubleshooting and my personal projects in SOC, Blue Team, data analysis, system administration and frontend. All from Fedora with KDE Plasma.
