Long-term, more important than Googling, is building a mental picture of 'who can be trusted to give solid advice or write great code'.
Nowadays, I don't hit StackOverflow, but go to GitHub to look at what the best Software Engineers I know did to solve a problem. For each topic, there is somebody that comes to mind that I think is better than everybody else, and I look to them for direction.
The GitHub Code Search feature is really useful. If I run into a weird problem that's somewhat outside "mainstream" programming (e.g. 2D Line Arrangements with CGAL), I'll often use Code Search to try to find repos that are using the API I'm using to see how they used it.
Hmmmmm that’s an interesting question! I think the GitHub search has a better semantic understanding of what I’m looking for, but I’m going to have to try it out!
