Now that the 4th prof. van Duck's article is in press; it's time to think to the next one.
Barbara Beeton suggested to me to read this article: https://latex-ninja.com/2019/02/26/guest-post-confessions-of-a-latex-noob/ and I've found it quite interesting.
It talks about the difficulties tackled by a newbie when s/he's asking for help, especially if s/he is not a mathematician or a computer scientist, but a humanities scholar.
I'm not talking about the difficulties in learning (La)TeX itself, but the ones to deal with when you're asking for help.
I agree with many of the things reported by the author, in particular, when she says that the experts criticize the (perfectly working) newbie's code only because it is not elegant, or when they use terms/acronyms a beginner could not know.
And I give her +1 for:
Have you ever tried to get a nice document done with Word, including lots of pictures? Yes, there is a good chance you will kill yourself trying.
My question is: which are the behaviors to be avoided when helping people, especially if they do not know anything about programming?
Edit: the answers given till now (thanks to who answered) are referring to TeX.SE. I would like also some general advice. For example, if a colleague from the humanities department ask you for help, what should you avoid doing?
Moreover, as AndrewT pointed out, we already have a Code of Conduct who tells to be friendly, etc. I would like something more practical, like the two examples I wrote above.
Your replies will be used by Herr Professor Paulinho van Duck in 5th article on the TUGBoat. He reserves the right to not include an answer because of moral scruples.
