I don't know about you, but some very coincidental things have happened to me. These have often been pretty significant, such as getting the jobs that mattered, improbable, such as running into people in unusual places, or just spooky, such as finding myself mentioned in a novel. Here's a collection of events that are all absolutely true; I'm not nearly clever enough to fabricate any of them!
How I got my first programming job
How I got my faculty position at Penn
Crossing paths at the Frankfurt airport
