.. Asking non-programmers for this sort of advice sounds like.. Asking your grandmother how to fix the internals of your car (or some other suitably apt comparison that is failing to occur to me)
You don't know - the OP's grandmother may be a mechanic. A more apt comparison is to ask me about the internals of a car. That's likely to convert your $30,000 car into an oversized paperweight if you follow any of my directions. Exceptions: filling up with gas, going faster, slowing down, and turning. Don't ask anything more complicated than that.
