There was a power outage last night, so my computer had to be restarted in the morning. I did so, forgetting that the boot order starts with the DVD drive, which presently contained a copy of T/Raumschiff Surprise, a very, very bad German Star Trek parody from 2004. Before I knew what was happening, it had installed OttOS, reformatted the primary hard drive partition, and copied 500 video files that all showed Darth Vader riding a hoverboard off a cliff while wearing an impractically large cowboy hat. This is the real reason why computers don't have disk drives anymore.
