Do you agree with these 29 things every beginner developer should know?

No. This is generic advice (useless without context) under a clickbait title. I think this is spam and have flagged it.

I'd disagree with "Know how to use Vim", why? I can use nano if I'm on a Ubuntu server (the only server I interact with).

I agree with everything except: "Know how to use Vim" -> I use nano "Pair Programming" -> nice, but not should

I agree.
