Collision Detection, a while ago, pointed to an essay by Eric Raymond, the open source guy, called….you might want to be sitting down for this…. “Sex Tips For Geeks: The Art of the Pickup”
I have not actually read the essay. Its a tough choice: should I actually go and read it, or should I gouge out my eyeballs with a grapefruit spoon?
(I got it from collision detection.)
