It would be nice if the results of the queries could be part of the gist. I would be interested in seeing some of the results without needing to run the queries

@EntilZha - Seconding this; that's what I was expecting when clicking the link in the blog.

I'd love to see a more complete list of universities included, besides just .edu, e.g. *.ac.uk. In many places I guess (e.g. France, Germany), the universities aren't grouped under a common domain, so an explicit list like https://github.com/Hipo/university-domains-list is necessary. But just searching for ".edu" or ".ac" at the second-level would catch a big percentage of sites like those at .edu.cn, .ac.jp, etc.

Is there anyway to get "committers" not "contributors"? What I mean by committers are those who are authorized by the open source project community officially as committers.

The format of queries appears to have changed slightly. For example, I needed to rewrite the first query to

SELECT count(*)
FROM (SELECT id, repo_name, path
        FROM `bigquery-public-data.github_repos.sample_files`
      ) AS F
JOIN (SELECT id
        FROM `bigquery-public-data.github_repos.sample_contents`
       WHERE NOT binary
         AND REGEXP_CONTAINS(content, 'This should never happen')) AS C
ON F.id = C.id;
