I said I would get back to it. Hamish led me to the quotes of Edsger Dijkstra as a(n ex) teacher, the one I really liked was:
"I mean, if 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself: 'Dijkstra would not have liked this', well that would be enough immortality for me."
Another gem though is
"Do only what only you can do" And do it Good
