Earlier this week, I had the honor to be a mentor in the Hack for Earth hackathon. I had signed up to be a mentor for open source, open data and anything related to Wikimedia. Unfortunately, I didn’t get any questions that were related to this, but I did get the chance to help some of the participants to find their way around the challenges and the formalities of the contest. And I did get to record a tiny “Hello!” video that got a small spot in the closing ceremony of the hackathon.
