Events and Activities

March: Participation at the Wikimedia Conference

The Wikimedia Conference is an annual meeting of the Wikimedia Foundation's developers, sysadmins, the MediaWiki comunity developers and Wikimedia chapter representatives. Manual, Emmanuel, Asaf, Pascal, Fabien and Tomasz participated in the meetings and set up a working group called "Wikimedia Offline". There we met people from PediaPress and started to think about integrating ZIM into the Extension:Collection which is currently used for the book prinitng capabilities of MediaWiki.

Due to this working group - which happened to be dominated by people that are already working at openZIM or have heard about ZIM already

June: Participation at LinuxTag

LinuxTag is Europe's biggest exhibition and conference for free and open source software. openZIM applied for a booth in cooperation with tntnet, so we got one booth for both projects.

By this opportunity we created nice graphs to show how the ZIM file format is used and how it works internally. These were printed as A2 posters and showed at LinuxTag.

Media Coverage

After a very good start and a lot of attention due to our Wikipedia DVD the numbers of visitors, visits and page views decreased slightly but remained stable. The mothly hits remained on the same level though while the traffic increased by 50%! Now there are about 2'500 (3'000) unique visitors, 4'000 (5'000) visits, 20'000 (28'000) page views and more than 50'000 (50'000) hits per month, in average 0,75 (0,5) Terabyte of traffic each month. (Numbers in parantheses are numbers of 2009.)

Wikimedia CH generously continued and increased its sponsorship of openZIM with now 9'000 CHF. This money was spent to run a server for the project providing a technical infrastructure (CPU time for ZIM file creation, download area, version management software, bugtracker, wiki, website, virtual machines with other operating systems etc.), for Developer Meetings and the participation at important conferences such as the Wikimedia Developers Conference in Berlin, Wikimania in Gdansk and LinuxTag, Europe's largest open source event. As openZIM is exclusively run by volunteers openZIM tried to cover most costs for meetings including accommodation and catering for all participants. Travel costs, though, have been paid by the participants.
