I tried to contact 3 developers of restify (famous node js package) to tell them about my library anumargak (node js based router). I received the response from one guy finally who talked to other developers when I explained the advantages of switching to this new router.

They all were happy to switch and asked me to do necessary changes and raise a PR. I did it and then they stopped responding.

Backend API developer that doesn't admit his mistakes. Damn, he's annoying the whole team.

Basically crashed the whole app by messing up the settings for the CORS policy, and still doesn't admit it. When he fixed it, the only reply we get was "I erased the thing and put it back and it works".

WOW!
