An overnight hackbot run lands a real CVE in Adobe Magento. Codex starts driving local Mac apps in parallel, with per-app permissions and a separate cursor. Cloudflare publishes one of the prettiest debugging writeups of the year — a nine-year-old kernel patch, a 14ms oscillation, three lines of fix. Plus Nous Research's removable attention wrapper, GPT-5.5's first ProgramBench solve, Vercel's argument that giving an agent a file system changes how it behaves, a 26-million-parameter tool-calling model, Isomorphic's two-billion-dollar Series B, and a Purdue senior who put Rust on his graduation cap.
