This advice is equally applicable to assisting your relatives with computer problems.
After all, programming is just a subset of mathematics anyway..
It's more of engineering subset. The resulting artefacts are rarely mathematically provable (bugs and Rice theorem).
I am quite proud;-) to have once trolled a group composed of mathematics and computer science students with one sentence: "What is computer science? It's that part of mathematics which is of any use." (FTR: I'm a theoretical mathematician turned programmer.) The best part (I think) is that it has some truth to it!
Not sure it is such a sick burn for mathematicians. A lot of these guys see non-usefulness (maths for maths itself) as a badge of pride! :)
I'm at the stage where I constantly notice this, which adds to my already non-zero job fatigue. I try to keep my sanity by threatening (myself) to start my own company, but maybe I just need to stop caring and grow up...
