During my 3rd year in college

Linux. During my 3rd year in college, I got obsessed with the concept of open source software. It all started when I read the life and early works of Richard Stallman, the father or free software. Stallman graduated in Harvard University in the 70s majoring in Physics, but his passion is more on software programming. He continued his studies in MIT and became a "hacker" in the MIT Artificial Intelligence lab. When he started the GNU project in the 80s, a lot of people joined the project. His concept of "copyleft" and its GPL license became so popular it attracted followers. Then in 1991 Linux came into picture. A programmer from Finland named Linus Torvalds wrote an open source kernel an integrated it with many GNU applications to build a complete operating system. This open source movement led me to hate Windows. I began to research about the Linux operating system. Using Fedora Core as the Linux distribution, I did some experiments in networking and basic system configuration. Then I move into playing with the user interface. I also tried multiple distributions like Debian, OpenSuse, and Slackware before settling with Ubuntu.
