Once upon a time, in the magical land of Software development, there was a young developer, your humble servant, discovering Linux for the first time. Suddenly, I had access to the Linux shell, a tool offering many ways to automate everything I didn’t want to do again and again.

But Ubuntu wasn’t without drawbacks. I was often the victim of display bugs and crashes, and it was getting slower and slower as time passed.

One day, something terrible happened: I had to update Ubuntu to its next major version. Everything crashed. I couldn’t start my system anymore. I had no idea how I could solve the problems I was facing because I had no idea how Linux was working under the hood. Ubuntu was abstracting all the nitty-gritty for me not to care about it.
