The smart city is the digital city, and the visions of what technology can do for society and humankind in the future are almost dizzying. Hackathon is a word that combines “hacker” and “marathon”, and that’s exactly what a hackathon is about. During H22 City Expo, programmers and tech nerds join visitors and changemakers to crack the challenges of the future within a given timeframe. Here, global problems will be solved and innovative ideas tested. But a hackathon is not just hard work, it’s inspiration and unexpected encounters wrapped up in a party atmosphere. Meet like-minded disruptors, take in some lectures, and have fun online or IRL – around the clock! Here you can see which hackathons you can join in during H22 City Expo.
