WattFactory turns your smart trainer into a full indoor cycling experience — ride real-world routes with gradient resistance or follow structured ERG workouts, all from your browser. No app install required. WattFactory works directly in your browser using Web Bluetooth and Web USB — connect your trainer in seconds and start riding. Plan a real-world cycling route and ride it virtually. Your trainer automatically adjusts resistance to match the gradient — climb the Alps from your living room.

I Built an Indoor Cycling Web App to Get in Shape Through Gaming2024 · startona.com · ▲13I spent the past three years developing an exercise game for indoor smart trainers called Startona.

The result is a PWA that showcases the capabilities of a modern web browser through technologies like Web-Bluetooth and WebGL. Developed to turn turbo-trainer workouts into intense gaming sessions, Startona combines structured workouts with exercise games that boost specific aspects of the player's fitness, such as speed, power, and endurance. Although Startona is built for fun by providing new and unique…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
