So, in my second semester of CS I had a class about OS and the way they work. The professor made us do presentations every two weeks (we were basically giving the class...).

For full points we had to have the presentation, an example (video or pictures), and an activity.

My team was one of the last presentations of the first round (iirc there were 5 rounds). I was in charge of the activity, so I decided to create a program to make it fun (and leaned a new language in the way). Thanks to this the professor gave us extra credit because we were the first team that ever did that.

My classmates decided that it was a good idea to follow my idea and a couple of teams started to code their activities too. At the end of the semester almost every team had a program as their activity...
But the professor didn't gave them extra credit because it wasn't a novelty anymore. :D

In another round, my team got as a topic encryption. By the time I was already a Linux user and I knew a thing or two about encryption, so I decided to do the example in real time showing how to encrypt and decrypt using command line. Once again we received extra credit because of it. :D

At the end of the semester the professor offered me a job as a developer, but I couldn't take it since I moved out of the country the next month :(
