The first time I saw Fedora, I was 15 or 16 years old. Someone I knew was trying (and failing) to install it on their computer. I'd never seen an OS other than Windows. I was intrigued and started asking the person many questions. He told me this OS was free to download and install—and I could even install it on my computer—but I did not believe an OS could be "free as in free beer[1]."
I went home and started poking around on the internet for more information, but I was too nervous to download it. The reason? The internet in India was not very fast (at least not in my apartment), and it had a data cap that could have been exhausted by downloading an OS. Yes, I know it was probably a gig or less, but I did fear of using up all my internet, so I moved on.

Three years later, during my sophomore year in college, the university required us to use Ubuntu for all the lab assignments in my Data Structures course. A professor taught us the ABCs of how to boot up and use Ubuntu, more specifically gedit and terminal, and my journey with Linux really started. I installed Ubuntu 12.04 LTS on my laptop and enjoyed using it for my development assignments and other tasks. But I soon realized it was not perfect; for example, my videos did not play as well as they did on Windows 7. That and some other things drove me away from Linux as my everyday OS, but all my development remained on the platform.
