[Mesa-dev] [Intel-gfx] gitlab.fd.o financial situation and impact on services

Fri Feb 28 21:37:03 UTC 2020

Hi All,

I know there's been a lot of discussion already, but I wanted to respond to
Daniel's original post.

I joined GitLab earlier this month as their new Open Source Program Manager
[1] and wanted to introduce myself here since I’ll be involved from the
GitLab side as we work together to problem-solve the financial situation
here. My role at GitLab is to help make it easier for Open Source
organizations to migrate (by helping to smooth out some of the current pain
points), and to help advocate internally for changes to the product and our
workflows to make GitLab better for Open Source orgs. We want to make sure
that our Open Source community feels supported beyond just migration. As
such, I’ll be running the GitLab Open Source Program [2].

My background is that I’m the former President and Chairperson of the GNOME
Foundation, which is one of the earliest Free Software projects to migrate
to GitLab. GNOME initially faced some limitations with the CI runner costs
too, but thanks to generous support from donors, has no longer experienced
those issues in recent times. I know there's already a working relationship
between our communities, but it could be good to examine what GNOME and KDE
have done and see if there's anything we can apply here. We've reached out
to Daniel Stone, our main contact for the freedesktop.org migration, and he
has gotten us in touch with Daniel V. and the X.Org Foundation Board to
learn more about what's already been done and what we can do next.

Please bear with me as I continue to get ramped up in my new job, but I’d
like to offer as much support as possible with this issue. We’ll be
exploring ways for GitLab to help make sure there isn’t a gap in coverage
during the time that freedesktop looks for sponsors. I know that on
GitLab’s side, supporting our Open Source user community is a priority.

Best,

Nuritzi
