Plan mode is dead

https://www.aymannadeem.com/assets/images/plan-mode-is-dead/code-generation-vs-interfaces.png
The author built a desktop coding app called Nuanced to help with planning and AI-driven code generation, but it failed due to users not wanting to create large, structured plans. The app's design didn't address the need for humans to maintain a coherent mental model of the system as machines change it faster than humans can inspect changes.

The far side of the Moon provides clues to a previous magnetic field

https://ethz.ch/en/news-and-events/eth-news/news/2026/09/the-far-side-of-the-moon-provides-clues-to-a-previous-magnetic-field/_jcr_content/articleLeadImage/image.imageformat.carousel.742628719.jpg
Researchers at ETH Zurich used gravity and magnetic field measurements to determine the structure of a region on the far side of the Moon, concluding that it had a magnetic field stronger than Earth's 4.2 billion years ago. The findings support the dynamo theory for an early lunar core-generated magnetic field, which is still active today in some areas.
