Tuesday. Latent Space ships The Field Guide to Fable and Kenneth Payne posts The Fable of the Universal Schelling Machine — the third day in a row Fable is a lede item. Fast Company runs the receipt on Garry Tan's 37K-LoC-per-day claim (A developer looked under the hood), which hits HN. arXiv returns with 673 new items after Sunday and Monday's silence. Hugging Face ships LeRobot v0.6.0: Imagine, Evaluate, Improve. TechCrunch: The first American autonomous ground vehicles are fighting in Ukraine. Alignment Forum publishes Data filtering works a lot worse than you would expect. Slashdot: Research Universities Are Admitting Fewer PhDs. HN: Microsoft Can Track Users via a Windows Device ID.
