WeatherNext 3 is DeepMind’s latest global AI weather model that generates hourly, high-resolution forecasts by directly ingesting raw satellite imagery, predicting surface variables at ~5–10 km resolution and improving accuracy even in unseen locations. It’s built for industry use (e.g., renewable energy) and has aided operational forecasting such as hurricane landfall predictions.

Jellyfin 12.0 is a major stable release that drops the old "10" prefix and introduces a database schema rewrite with performance improvements (notably playlists/collections), multi-version support for episodes, and first‑class books/comics support. Upgrading requires a full manual backup and specific preconditions (must be on 10.10.7 or 10.11.x), removal of third‑party plugins, a required full library scan after migration, and attention to breaking changes like case‑insensitive usernames and removed legacy endpoints.

The post inspects how mobile agent platforms run per-tenant VMs on phones: Claude Code boots a Firecracker microVM with a sealed in-guest control process and read-only harness while inference is served remotely over SSE, and Instinct rents disposable E2B KVM sandboxes running Ubuntu where the agent persists memory as a git-backed Markdown vault pushed to S3 using short-lived STS creds.

The paper generalizes Ken Thompson's trusting‑trust attack beyond compilers by constructing a complete attack that manipulates finished ELF binaries (specifically GNU strip) to implant a payload that propagates across rebuilds. They demonstrate the attack in the NixOS bootstrap: a single tampered strip seeds a payload that survives dependency pruning and backdoors nearly every binary in a built graphical installer, enabling arbitrary malicious behavior across the distribution.
