My desktop runs Debian and doubles as a server: hosting my personal website using Apache, running a few game servers for my friends to use, hosting a virtual machine to serve as our network's DNS server. When installing Debian, I had to patch and recompile the driver for my Wi-Fi card in order to get it working. In configuring these things I've gained experience with both security practices and system administration. I'm confident that I can fix most issues that would come up under Linux, but I can't claim that I know everything about the system.
