  • Introducing GNOME 44, “Kuala Lumpur”
    That third graph doesn't do a good job of accurately assigning commits to organization. For example, two the largest GNOME contributors for Red Hat are Florian Müllner and Jonas Ådahl. Both of them don't commit using a redhat.com email address. Instead they use gnome.org and gmail.com respectively. So they are incorrectly assigned in the third graph to either Personal or other where they should be with Red Hat. Source: over 3 years ago
