...I'd say don't worry about it. There is a class of technician who believes it to be a personal affront when someone asks a question that they (the technician) already knows the answer to. Usually this sort of person will also take offense at being told a fact that they already possess.

Just keep posting your earnest questions and your earnest responses, and eventually the right result will occur.

I certainly thought this question worthy of a little thought. Many programmers are born puzzle-solvers and it's hard for those among us to pass up a good puzzle that needs a solution.

So keep contributing in good faith.
