FWIW, the German federal government (of all people), is organizing a distributed hackathon this upcoming weekend: https://wirvsvirushackathon.org/

Seems like it's supposed to be (mostly) in German language as well. If they do and market this right this might actually be an opportunity to get non-tech people to contribute important PROBLEMS that can be solved by tech right now, so we don't just get another few dozen news aggregators and case tracker dashboards.
