And I forgot to talk about Linux distros. The above guy said he uses Ubuntu 14, I personally use CentOS 6. The Linux kernel is the same, so you should choose the distro you like. When I was a beginner I didn't know what distro to use, so I just choosed Ubuntu as I heard it was the most famous Linux distro for desktops/laptops. Nowadays I prefer CentOS 6. As a CentOS fan I recommend you to try CentOS 6, but really, it's just a question of preference and I guess there's no "better distro", so choose whatever you want

Another distro that is worth mentioning is Debian, a very stable distro. Ubuntu is based on Debian btw, but it has customizations and branding by Canonical Ltd..
