China reaches energy milestone by ”breeding” uranium from thorium
An experimental reactor developed in the Gobi Desert by the Chinese Academy of Sciences’ Shanghai Institute of Applied Physics has achieved thorium-to-uranium fuel conversion, paving the way for an almost endless supply of nuclear energy. Advertisement The achievement makes the 2 megawatt liquid-fuelled thorium-based molten salt reactor (TMSR) the only operating example of the technology […]
Gwern’s ”Stem Humor” Directory
Annotations sorted by machine learning into inferred ’tags’. This provides an alternative way to browse: instead of by date order, one can browse in topic order. The ’sorted’ list has been automatically clustered into multiple sections & auto-labeled for easier browsing.

Agent design is still hard
written on November 21, 2025 I felt like it might be a good time to write about some new things I’ve learned. Most of this is going to be about building agents, with a little bit about using agentic coding tools. TL;DR: Building agents is still messy. SDK abstractions break once you hit real tool […]
