   Project mention: Server-Sent Events (SSE) Are Underrated | news.ycombinator.com | 2024-12-25

   You can also use the Web Locks API (https://developer.mozilla.org/en-US/docs/Web/API/Web_Locks_A...) rather than Broadcast Channel

   This library (https://github.com/pubkey/broadcast-channel/blob/master/src/...) from the fantastic RxDB javascript DB library uses WebLocks with a fallback to Broadcast Channel. But, WebLocks are supported on 96% of browsers, so probably safe to just use it exclusively now.

    Project mention: Show HN: Running Silero VAD in the browser using ONNX-WEB runtime | news.ycombinator.com | 2024-08-08

    I was able to run Silero VAD directly into the browser. It is very accurate and can detect speech irrespective of any language.

    I tried various libraries but none of them was user friendly. so, I wrote one myself. Under the hood, it uses onnx-web-runtime to run the model.

    I was able to do it in 2 days. I used Claude 3.5 to help me port code from Python to JavaScript. That helped me speed up the whole process.

    I am publishing the Next.js template code. Going forward, I will convert it into an npm package for easy install.
