I just spent the last hour debugging a Linux user / permissions problem. On the one hand, maybe I wouldn't have to deal with this on a closed system. On the other, as soon as I finished, I was so grateful for Linux. I was grateful for the fact that I know that there is nothing in this computer that I can't change or need permission to access or edit. Where would we be without Linux? It's really the base we are all working on. Love open. Love Linux.
