Tests first is only good in theory.

Unit tests typically test rather fine grained, but coming up with the structure of the grain is 80% of the work. Often enough you end up with code that’s structured differently than initially thought, because it turns out that this one class needs to be wrapped, and this annotation doesn’t play nice with the other one when used on the same class, etc etc.

Especially then I’d test the shit out of everything? I’m getting paid for writing correct software.

Not a sysadmin, but a capable user.

People shouldn’t just accept technology as magic. They should understand at least the basic principles of the technology around them. Corporations want us to be dumb and incapable. Look at cars, you seriously can’t expect a normal person to fix anything on them. But that’s not because of inherent complexity, but because corporations want us to just buy new parts when they think it’s time.

Sapere aude was true in the 19th century and it’s true today as well.
