There are some crazy theorists out there who conjecture that we spend more time and work on creating time saving devices than it would ever take to perform the task in the first place, but as we said, those guys are crazy -- either that, or they're just jealous of Alexandre Novello and his l33t hax0r skills. It seems Alexandre grew tired of walking across the room to open the door for people, so he wrote himself some software and hooked up to the door's electronic opener via a hardware switch and a parallel port. Sounds like a nice calorie saving scheme he's got going, keep on slacking hard Alex!
