Tiago Vignatti has now compiled some statistics surrounding the top contributors to X.Org Server 1.9 and related X components just looking at this most recent development cycle. There's also numbers for the input, video, and Mesa components too.

Below are various bits of information gathered from Tiago's statistics.

- Alan Coopersmith was the developer with the most change-sets to X, which Tiago counts as the X Server, proto, library, and XCB repositories. Alan accounted for 15.3% of these changes through his work at Oracle, after being a long-time X developer at Sun Microsystems. While Oracle may be doing nasty things to other open-source projects they hold stakes in and doing things like killing off OpenSolaris, they are at least so far letting Alan continue to contribute back to upstream X. The 2nd through 5th most active developers were Jamey Sharp, Gaetan Nadon, Keith Packard, and Tiago Vignatti, respectively.

- While Alan had the greatest number of change-sets to the X implementation, when it comes to the number of lines of code that were changed, his work fell into second place (at 23.4%) with Matt Dew accounting for more than 50% of the changed lines!
