Christmas markets in Cologne in 2025

Each Christmas tree 🎄 shows the location of one of the 9 Christmas markets. I created a Christmas tree flat icon as an SVG and imported it into mapbox.com Studio. Finally, I discovered the particle-based snow setting. ❄

AI presents a fundamental threat to our ability to use polls to assess public opinion. Bad actors who are able to infiltrate panels can flip close election polls for less than the cost of a Starbucks coffee. Models will also infer and confirm hypotheses in experiments. Current quality checks fail

new paper by Sean Westwood:

With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research
