ChessLFM went full circle and is now on the home page of @lichess Super cool to see, Lichess is where I collected all the seed data. Based on my limited chess skills, I never thought I'd have an article there.

Using burgers as a model system, a generative AI system rediscovers the classic Big Mac without explicit supervision and generates novel burgers optimized for deliciousness, sustainability, or nutrition, according to a paper in npj Science of Food. go.nature.com/3SU7JDQ
This is figure 2, which shows rediscovering classic burger and discovering delicious burgers.

I had a great time chatting with @fishnets88 about EVoC -- the interactive tools for @marimo_io did an amazing job at making the speed and cluster layer effects much clearer and easily explorable. It is definitely worth a watch if you have time. piped.video/watch?v=ES4PPjK2…

Sad story in two acts.
Git diff view. Before: # Google Summer of Code 2026 Welcome to M-Lab's Google Summer of Code page! We're excited to have you here and look forward to working with talented contributors from around the world. After: # Google Summer of Code 2026 Measurement Lab had to drop out of GSoC. The motivation for this decision is that, due to the massive usage of AI, we have seen a large volume of similar and incremental contributions that our team cannot handle.
