Recent events

 * October 2011 Coding Challenge (20 October - 7 November, online) —


 * India hackathon (18–20 November, Mumbai, India) — Approximately 80 Indian participants came to this week-end hackathon, focusing on Wikimedia mobile, offline, and language issues. According to Phil Chang, participants made great strides in mobile. The internationalization effort also benefited, with new input methods for MediaWiki, readying Narayam for Wikimedia Incubator, a prototype onscreen keyboard built in Narayam, Wikimedia Mobile ready for translation, new UI prototypes for language selection, and other new features. Participants localized Kiwix into several Indic languages. Volunteer Development Coordinator Sumana Harihareswara summarized the event on wikitech-l.


 * Brighton hackathon (19–20 November, Brighton, England) — Lewis Cawte and Tom Morris organized a general MediaWiki hackathon with approximately 10 participants. Attendees fixed bugs, reviewed outstanding patches from volunteers, enhanced OpenPlaques with the MediaWiki API, and discussed Wikinews and Wikimedia Commons.

Upcoming events

 * San Francisco hackathon (21-22 January 2012) — Erik Möller and Sumana Harihareswara continued to plan and started publicizing an outreach-focused developers' week-end. Experienced staff and volunteer developers will participate, "teaching you about MediaWiki (our software), about our API and about our framework for JavaScript feature development. Learn to reuse Wikipedia content in your own apps, create new functionality for every Wikipedia user around the world, or just tailor your own experience."

Short news

 * Benny Situ and Rob Moen joined the Features engineering team as Software Developers, to work on Editor Engagement features (announcement for Benny, announcement for Rob).

Site infrastructure

 * Data Centers —
 * New database servers deployed for external storage


 * Media Storage —  Ben Hartshorne set up the initial production environment; meanwhile, Aaron Schulz started to refactor the FileBackend extension.


 * HTTPS —  The HTTPS Everywhere project released version 1.2 of its Firefox plugin in October.  Its rulesets did not properly account for the HTTPS configurations of certain Wikimedia sites, so Roan Kattouw followed up with improved rulesets in November.

Testing environment

 * Virtualization test cluster —

Backups and data archives

 * Data Dumps — While the dumps keep rolling along, we are talking with another organization interested in mirroring them. If you know someone with several terabytes of space who might be interested, please send them our way. All hosts had their kernel updated for security reasons, and new dump code was deployed as well. We rolled out a new experimental service this month of daily adds/changes dumps for all projects. No information about deleted/undeleted/moved pages from previous dumps is included, but it does include all new content since the run of the previous day. The first adds/changes run for the English language Wikipedia took less than 30 minutes to build.

Bryan and Antoine also wrote a comparison tool, [//test2.wikipedia.org/wiki/Special:VipsTest enabled on the test2 wiki], to test both systems. The initial deployment is planned to be limited to images that would give an error with ImageMagick (for instance large PNG files).
