SitSense is an AI-powered posture tracker and coach that uses your webcam to analyze posture in real time โ no wearable devices, hardware, or app downloads required. Built on Google's MediaPipe computer vision framework, SitSense tracks 7 core posture metrics including forward head posture (tech neck), neck angle, trunk alignment, and shoulder slope, delivering instant feedback and coaching directly in your browser. Designed for remote workers, software engineers, students, and anyone who spends long hours at a desk, SitSense detects the subtle alignment changes that cause neck pain, back tension, and mental fatigue โ and corrects them before discomfort builds. Analysis of 540+ hours of real user posture data shows most strain begins with small shifts that go unnoticed without real-time tracking. Unlike wearable posture correctors like Upright GO 2 or the discontinued Lumo Lift, SitSense analyzes full upper-body posture through your existing webcam with over 90% accuracy. All video processing happens locally on your device โ no video is ever recorded, stored, or transmitted. Features include real-time posture scoring, personalized AI coaching, streaks, leaderboards, daily goals, and session analytics. Works on Chrome, Firefox, Safari, and Edge on Windows, macOS, and Linux. Free 3-day trial, then $34.99/year.

Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 6 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 9 months ago

In the code editor tab (powered by StackBlitz), navigate to the env.ts file and enter your OpenAI key. Run npm run generate in the terminal to see how @autoview generates TypeScript frontend code from example schemas derived from both TypeScript types and OpenAPI documents. - Source: dev.to / over 1 year ago
