In the good ol' times, when Computer Science was young and open like the ocean, brave captains were more mathematicians than developers. Also, they had great beards.
They opened routes, fought monsters, discovered unknown lands, and we had fun on this ever since. As time goes by, we seem to forget some of their warnings and wisdom.
It's time to roll the treasure map and find the buried chests of pure gold advice!
