professional developer for close to 20 years, never used calculus. but i also a dumb java on the backend javascript on the front end web jockey.

To be a developer you don't even need to go to university. I know a lot of valid developers with a technical high school diploma, and I see that most of the time are better than a lot of people with a degree (or even a master degree).

To this days to be a developer university must be seen just as something extra that you do if you want to occupy positions that goes beyond being a simple programmer.

Some might say that's representative of the majority of the field..!
