🚨 Anthropic just showed a 27-minute workshop on how to actually do prompts for Claude. Taught by the people who built it. Free. No registration. No paywall. I've seen $300 courses that don't cover what they teach in the first 8 minutes. Watch it and bookmark it now.

The laptop hasn't changed in 30 years. NVIDIA just changed it RTX Spark is their first PC chip ever. - RTX 5070 level GPU - 128GB unified memory - 1 petaflop of local AI - thin, light, barely throttles unplugged Your AI agent lives on the machine. 24/7. No cloud. This is step one of the agentic AI PC, and everyone else is about to copy it.
Introducing Surface Laptop Ultra. Built for world makers. Designed for what's next. The most powerful Surface laptop ever. Coming Fall 2026. Sign up to learn more: msft.it/6019vw79T

This #CVPR2026 paper from our research team is trending #1 on @HuggingFace πŸ€— Meet LocateAnything: a vision-language detection model that rethinks bounding box prediction. For AI agents and robots, β€œseeing” is only useful if a model can pinpoint where something is fast enough to act. Trained on 138M high-quality samples, LocateAnything decodes bounding boxes in parallel instead of one coordinate at a time, improving localization accuracy while dramatically increasing throughput for visual grounding and detection.

The talks with Prime Minister Meloni were excellent. Her commitment to furthering the India-Italy friendship is commendable. Bilateral ties between our nations have advanced significantly in sectors like trade, space, technology and more. In order to further deepen linkages, we have elevated our ties to a Special Strategic Partnership. @GiorgiaMeloni
