Inside Meta's 83,000-GPU AI Supercomputer: Why It Runs the Silicon at 80% Power on Purpose

Meta's first end-to-end account of running a 150 MW, 83,000-GB200 cluster - when power is the ceiling, the cluster, not the chip, is what you optimize.

Thermodynamic Computing's First Silicon Is Back from the Fab. The Power Math Comes Next.

Normal Computing's CN101 is in characterization. Extropic has a prototype platform, an MIT-co-authored arXiv preprint, and an ETH Zurich hackathon in June. After two years as a manifesto, thermodynamic computing is producing the kind of artifacts readers can evaluate.

When the Grid Says No: Denmark and the New Shape of the Power Question

Energinet didn't pause grid connections in a contested metro or a zoning fight - it paused them because 60 GW of queued demand met a 7 GW national peak, and the math stopped working.
