I use Ubuntu for multiple reasons, and mainly as a back-up to when Windows decides to fail, or I wish to have a USB whose data contents would be best secured (and wish to have a tool to use whenever things go even more wrong) with the ext4 filesystem.

I have a moderate degree of knowledge about Ubuntu, but I will not claim any sort of mastery.

I also program a little in Python whenever I feel up to it, and frequently play Minecraft on the server "The Canadian Sandbox" (whose webpage is linked on my profile somewhere).
