I feel the opposite. Often I'm searching some obscure error message or function name from an open source project; I'd expect Google to at the very least provide a result linking to the Github page where the thing is defined, but nope, nothing. Bing on the other hand gives me exactly what I'm looking for in the first few results.

This has been my experience. Google can now not even find substrings from source code found in thousands of GitHub repos. It's rapidly getting useless for programming.

Google doesn't seem to index all of github, which is very frustrating when looking for code strings or error messages that you know are included in some opensource project.
