It's nice when devs are
happy you find bugs in their code, like I don't want to bother them with issues so saying thanks is positive

My current boss a while back (before he was boss): "My code is pure!"

Me: "Pure shit..."

Him: "How dare you!?"

I love it. I need it, me needs bugs to squash cuz me have god complex, yes, me have

That‘s how you distinguish between good devs and shitty devs.

Good devs are glad to be told about bugs in their code because they care about their code and they consider bugs an exception that needs to be exterminated.

Shitty devs see reported bugs as an insult to their ego and are offended, or they don‘t give a fuck because they consider bugs to be normal.
