Election Hackdays

Election day in Switzerland is coming up this fall, and we’ll put politics and election data at the centre of the next hackathon. Designers, programmers, journalists, specialists and citizens of all backgrounds will be working on useful app ideas, interesting visualizations and new datasets for the Federal Elections during this two day workshop.

The Federal Elections Hackday will be held on September 4 and 5, 2015, at two venues in parallel: the offices of Neue Züricher Zeitung (NZZ) in Zurich and Le Temps in Lausanne. Developers, designers, hacks and hackers will be working with open data on the subject of politics and elections. Participation is free of charge. The hackdays start on Friday, 4th of September, at 9 o’clock and end with final presentations the next day at 16 o’clock.
