I had this happen with a mid level guy (who thought he was a senior) with a cowboy attitude towards code. After many attempts to reason with him, I revoked his permission to touch the main branch and stopped reviewing his code until he started behaving. He left soon after.
In your case with a senior I’d escalate the situation to management.
I would ask on reddit, IRC channels or read the documentation. I found that I rarely get an updated answer on stack overflow for my area of work.

I really hope it burns to the ground. One of the most toxic dev “forums” I’ve seen. I made a point of never clicking their site when looking for answers even if it took me longer.

IDEs have boosted significantly programmers productivity.
