Now, kids here's a new programming challenge: one estimed FB programmer travelling in direction A one estimed FB programmer travelling in direction B where A and B will meet head on what is the speed of each programmer after collision? Is 100% of the heat of the argument translated into velocity or does a portion get consumed by mail bots? Is that what we normally see in nature? participants are free to include variables covering such things as: - the geographic location of the programmers - the number of respective posts to the FB list - the use of PG - wisecrack jokes in mails especially if these variables have no relation on the outcome of the collision, but generate in turn lots of challenges... [erm, just joking kids] ;-j [gnome rapidly meeting a large heavy objeeeeccccttttt!]
