What seems to be lost here is that zebra crossings are not merely crosswalks: the pattern on the pavement is significantly different. Instead of it being two parallel lines in which you walk, a zebra crossing has wide, white rectangles perpendicular to the pedestrian, creating an alternating black and white design. (Think Abbey Road cover...)
The effect when a pedestrian is walking in the crossing is that of an interference pattern, which it makes it easier for cars to see them.
Now if you reread the joke again, it will make more sense...
On the other hand, their advice to use tcsh/bash as a sudo command is poorly thought out. How is that any better than su? Better to use sudo with a few simple commands and scripts that need root for 80% of cases, and use su for the rest.
The su command won't work if the root user is disabled (which it is by default).
Another protocol that can be used for shared address books is IMSP, which was written as part of Carnegie-Mellon's Project Cyrus. The problem is that few applications support it. In fact, the only one I know of is Mulberry.
