Transcript of Gnome census
The GNOME CensusWho writes GNOME?
Dave Neary, Neary [email protected]
Why?
Potential GNOME partners
Press
Big institutional clients
Vertical application developers
Headhunters?
Methodology
GNOME 2.30 release
Selected external dependencies omitted
Changesets, not lines of code
No deprecated modules
GNOME Mobile not considered
Tools
Gitdm
CVSAnaly
Shell scripts, MySQL, Gnumeric
Manual labour
Data quality
Multiple email addresses per person standard
src.gnome.org, svn.gnome.org, cvs.gnome.org added noise
Not straightforward to match domain to employer (eg. ubuntu.com, gnome.org, debian.org)
Time a factor
Data quality
Maintainers regularly committed for others
Merged branches squashed
Human error
Survey
Designed to improve data quality
Interested in seeing how GNOME developers self-identify
18% response rate good, but not great
Room for improvement in employer data - Unknown = 17% of commits

Interesting observations
git vs svn vs cvs
Mix between thousands of commits in 1 or 2 modules and hundreds of commits in lots of modules
High positions for unpaid contributors
70.27%
19.93%
GNOME is a volunteer project
>70% GNOME commitsfrom paid contributors
But...

Analysis
Red Hat top individual corporate contributor11 of top 20 individuals current or former employees
Driver behind many freedesktop.org projects
Novell more focused on applications
Collabora - GStreamer and Telepathy
Analysis
Canonical low on listprimarily integration & packaging work
Now doing development, but work not yet submitted to GNOME
Nokia strategy of pushing start-ups successfulCollabora, Lanedo, Openismus, Codethink, Igalia all feature well
Igalia not in top 20 because WebKit & GNOME Mobile not included
Who maintains GNOME?
Thanks! Questions?
