Hi all,
Wikimedia Czech Republic and I are collaborating to organize a pre-hackathon https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2017/Prehackathon_Prague in Prague that runs from 12-14 May 2017, a week before the hackathon in Vienna. There are a few scholarships available that will cover the return trip to Prague/Vienna, and/or accommodation in Prague during the pre-hackathon.
The topic of the pre-hackathon will be the improvement of the Wikimedia Commons Android app https://github.com/commons-app/apps-android-commons, with focus on the "Nearby places that need pictures" feature. Further details are currently still being discussed here https://github.com/commons-app/apps-android-commons/issues/353.
If you are interested, please register https://docs.google.com/forms/d/e/1FAIpQLScvPa8LIz_YTOIcToaAAkAvnZ5OoJ2F5YUlfelDcTcutL24cg/viewform as soon as possible and indicate if you would like to apply for a scholarship in the application form. For any enquiries, feel free to send me or Vojtech (CC'ed) an email, or post on our GitHub or wiki discussion page.
Cheers!
