First year of my study (application development) (5 years ago).

We were finally starting getting courses on using Linux and the teacher knew I was already using it for a while so he said that I had to finish the assignment but could work on whatever I wanted next to that.

Assignment was installing a server, getting a web server up and running and compiling at least one program from source.

I setup the server in 20 minutes, wrote a script to do the rest for me and was finished in half an hour. (we got 10 weeks for this (1 hour every week officially))

Well, I was about to start doing my own shit when people started asking me for help.
Fuck it, I love helping people with the things I'm passionate about so sure!

For weeks, during that one hour, I was probably the second teacher. Got called all over the classroom and helped people with everything.

Afterwards (the course), most people said that I probably helped about the whole class pass that course and I got called the linux God etc.

From that day on, my nickname at my study, which even many teachers used was: Mr. Linux.

It felt awesome though!

And still whenever I visit that place again, one teacher always goes: Hello again, mr. Linux!
