I've contributed to Go, but when I tried to add Go to the "Open Source" section of my Careers profile, Careers refused with the message "Hidden We couldn't find any commits you've made to this project." Why won't Careers display my contributions to Go?
The issue originates from Github not linking your commit with your Github account, even though the email addresses (in the commit and on your profile) seem to match.
The issue isn't due to the fact you are an author and not a committer: we actually handle this case.
This looks like an edge case, I manually updated the project status on your profile so that it is not hidden anymore.
While you are the author of this commit, you are not the committer. The difference between author and committer is that the author is the creator of the content, while the committer is, well, the committer.
We unfortunately don't have a way of verifying the relationship between your Github profile and the Go project from the Github API: neither the list of your repos nor the list of contributors to the Go projects provide us with this information.
In this case, it would help if Github included the authors in the list of collaborators, but it's not the case and we haven't found a good way to work around it yet.
