Last month I taught @julia and its geospatial stack at the @opengeohub summer school 2023 in beautiful Poznań, Poland. I had a great time together with other open-source developers. Pictured is me calling in from the train home, because I won a hackathon by using Julia 🥳.

My materials (including the notebooks for the hackathons) are at https://github.com/evetion/OGH2023 and the recording(s) are at https://www.youtube.com/watch?v=UgMdr8vE9uM&list=PLXUoTpMa%5C_9s1C8LrkslIctOU31Oi0LAQa.
