Guide To Linux

History of Myself: Aaron Douglas D'souza

I am 28 years old, originally from London in the UK, though I now live in Manchester.

I hate the words "Noob" or "Newbie," but I was once a new Linux user. I started using Nobara around September 2023.
From there, I began creating a custom taskbar, which can be seen in the project link below:
Though the original color was burgundy and it was called "SpitFire."

Project Link: ApexKLGE-Minimal

More photos of my old projects can be found here:

I was originally an advanced Windows user who enjoyed testing betas and development builds.
In fact, I tested Windows 8/8.1/10/11 before their official releases and was testing KDE Plasma 6 before it came out.

I have also tested games like "Skull and Bones" by Ubisoft before their release. I like to get involved.

Since I am a game mod creator, music creator, and now a software engineer,
I have a lot of free time on my hands after putting my game mod updates on hold.

I've made tons of scripts and applications for Linux, and I wish to help others with what I've learned.

Below, you'll find many useful tutorials for Linux,
including application building and complex Bash commands that everyday users might not know.

More to come I will update this soon!
