OpenAI is extending its content provenance work to AI-generated text in the European Union, positioning the move as part of its response to the EU AI Act. The company is taking a phased approach: eligible API customers worldwide can opt in to text watermarking for select models, while watermarking for eligible ChatGPT and Codex outputs is planned for the EU in the coming weeks.

🌟 What I Built It runs an open-weight vision model locally on-device using WebGPU/Ollama, paired with an open-source agent framework (Mastra) to organize local trail findings, cross-reference native/invasive species databases locally, and log discovered flora. The app is built so that screen time is minimized to a quick 5-second snapshot, letting you get back to enjoying nature. 🍃 How It Gets People Outside ("Touch Grass") Fast Trail Identification: Snap a photo on the trail, get immediate identification and brief ecology insights, and immediately put the phone away.

Short answer: keep the board's event log authoritative, apply backpressure at the connection boundary, and test state convergence instead of hoping wall-clock sleeps line up. For a healthtech chat room or shared kanban board, presence accuracy is the decision axis: a delayed cursor is annoying, but a stale "online" clinician can misroute work. The useful contract is small. Every mutation gets an ordered sequence, every reconnect asks for a cursor, and presence is explicitly soft state with a lease. A test should control delivery and acknowledgements with a virtual clock.

It was waiting at the bottom of a sewer under the city of Waterdeep, and it wanted you to know it was there the whole way down. Eye of the Beholder — the first game in SSI's "Legend Series" of Advanced Dungeons & Dragons computer products — took the dungeon crawler, made it real-time, and aimed it squarely at the oldest fear in tabletop gaming
