I don't know how you'd get anything done since there are answers on Stack Overflow that solve problems that otherwise would involve hours to days of fussing to come up with the same non-intuitive solution.
All roads lead to Stack Overflow these days for progrmaming problems.
Just out of curiosity, do those 7.5+ million accepted answers include those closed as duplicates? Because by far my biggest complaint is finding the exact question I have was closed as a duplicate and links to a question that is useless at answering my question.
I have had the same experience with embedded programming questions. I suppose they depend too much on the hardware. I do quite a bit of programming with the beaglebone blacks (or at least the same processor). And it seems the best resource is the mailing list.
