I loved his articles in the ACM. They are collected in a book called Programming Pearls (https://www.amazon.com/Programming-Pearls-2nd-Jon-Bentley/dp...) I also liked his second book More:Programming Pearls (https://www.amazon.com/More-Programming-Pearls-Confessions-C...)

Some of the same articles, but with updates and added reader comments.

(I posted Amazon, but there is a ton on the used market)

Jon Bentley [1] had a whole chapter in More Programming Pearls: Confessions of a Coder [2], called Bumper-Sticker Computer Science, which was of this sort. There seems to be a copy of it online [3].
