I didn't think last two years Post GIS Day conferences could be topped, but I was wrong. This year's was absolutely fabulous and better than all the others.
We had two key conferences going on this year (yesterday). The first was the Cruncy Data PostGIS Day 2022 12 hour marathon of nothing but PostGIS related talks. Many thanks to Elizabeth Christensen and Paul Ramsey for putting it all together and for 12 hrs. The PostGIS day celebrations climaxed with many of us playing capture the flag on Paul's new shiny invention until we managed to crash it.
The other talks were great and hopefully will be out soon. Brian Timoney showed a mouth watering and suspenseful show that demonstrated the power of PostgreSQL, PostGIS, and freely available data working together. I pity those that missed it, but hopefully the video will be out soon.
The second event was given by FOSS4G UK Local. This was a new way of doing conferences I hadn't seen before and it worked surprisingly well. They had 9 simultaneous physical locations giving talks and also simultaneous live streaming. Very impressive and many of the videos are out already. There were some talks on PostGIS, but the event was focused on OSGeo projects and Open source geospatial in general.
There were three Keynotes at the FOSS4G UK Local live streamed across the 9 locations and virtually too. I gave the last keynote of the day and covered the progression of PostGIS. The video of it is here Post GIS Vision: Past, Present, and Future and slides here. The content of my keynote overlapped a bit with Tim Sutton (of QGIS fame). Anita Graser (of QGIS and Moving Pandas fame) keynote took a different direction with focus on Reproducible and Trustworthy Spatial Data science.
