Based on https://www.mediawiki.org/wiki/Hackathons#Measures_of_success, as agreed in {T88520}. It's the first time we apply this process, and we are doing our best to reply to all points.

* 20 nationalities
* 32 languages, T88521#1334300

* gender: 19,29% women
* 98 [[ https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2015/Buddies | buddies confirmed ]] (100% of the participants who requested a buddy on the first day got one assigned)
=== Hacking ===
* 33 projects showcased, see {T96378}
* FIXME: How many driven by volunteers?
* FIXME: Any projects that the WMF decides to support after the event? See {T101151}
* FIXME: Tasks resolved? (lesson learned: don't mix organization tasks with "genuine" hackathon tasks)
=== Training ===
* Overview of Wikimedia tech priorities and ongoing projects welcoming contributors, see {T93064} (although there was low attendance of newcomers and room for improvement)
* FIXME: How many newcomers & welcomers in welcoming session? (the numbers in the registration don't correspond to real attendance to the session)
* FIXME: Participation and results in other training sessions.
=== Meeting ===
* FIXME: Community decisions worth a face to face meeting.
* 4 events introducing Wikimedia to local teachers, students, and entrepreneurs
* FIXME: Social meetings and events.
=== Organization ===

* FIXME: How much funds pooled for volunteer travel sponsorship, and from whom.
* FIXME: Participants survey and summary report.
