On a serious note, when I do make a mistake, I make sure everybody knows it.

It ensures those more junior know it’s ok to fuck up. But I will also write up a short summary/post mortem so everybody can learn from my mistake.

Seeing how teams handle mistakes is a good indicator of culture.

I’m aware I’m turning a joke into a serious discussion, so I’ll just shut up now.

As a developer with over a decades experience, I can assure you I contribute my fair share of fuck ups.

Nobody is immune to mistakes, regardless of level.
