On the topic of increasing diversity, a tech task that can be driven by non-tech Wikimedians as well.
Wikimedia is planning to participate in Google Summer of Code 2015 and the simultaneous FOSS Outreach Program for Women round 10. We want to increase geographical diversity among candidates by involving local Wikimedia groups in the promotion of these programs. This, in turn, could help increasing the technical capacity of these groups. Interested? Please check
Connect Wikimedia groups, Google Developer Groups, and computer science university departments https://phabricator.wikimedia.org/T925
Italy, Russia, China, and Japan have been mentioned already. Adding other locations is up to you. We are looking for local drivers. The Engineering Community team and others can help from a distance, but this won't work without local promoters.
