Q.js – Smaller than React/Vue, yet more powerful (40KB gzipped)
Q.js is a lightweight JS framework that I recently distilled from our in-house Qbix platform that I’ve been building since 2011. It powers many of our social apps, which have all the features of Facebook, LinkedIn, X, etc. We’re not a big company like Google or Meta, so we never released it publicly. Now I’d like to, and thought it would be a good idea to post it on HN and gather some feedback. Q.minimal.js was designed to be dropped into any website.

In plain words
Q.js is a lightweight JavaScript framework built from a production platform used since 2011 to power social applications. At 40KB gzipped, it is smaller than React or Vue while offering comparable features. The framework lazy-loads components as they appear on screen and comes in a minimal version designed to be dropped into existing websites. Developers can start with Q.minimal.js and swap it for the full Q.js library if additional features are needed later.

Q.js is a lightweight JS framework that I recently distilled from our in-house Qbix platform that I’ve been building since 2011. It powers many of our social apps, which have all the features of Facebook, LinkedIn, X, etc. We’re not a big company like Google or Meta, so we never released it publicly. Now I’d like to, and thought it would be a good idea to post it on HN and gather some feedback. Q.minimal.js was designed to be dropped into any website. It lazy-loads all your components only as they are needed and appear on the screen. The minimal file is meant as a starting point for developers, and if you later want more features from the Qbix platform, you can simply swap it out for the larger Q.js file instead. Here are some advantages of Q.minimal.js compared to React, Angular, Vue, or whatever you might be using now: 40KB gzipped, smaller than React (without ReactDOM), smaller than Vue runtime, far smaller than Angular No build step, just drop it in; works with plain .html <template> files or with JS/Handlebars templates Components & tools, like React components or Vue directives, but attachable as behaviors to any DOM element Faster rendering with requestAnimationFrame and .rendering(), no giant virtual DOM reconciliation Built-in power: batching, caching, lazyloading, routing, slot-based page activation, all included in core Universal dev model: designers can use pure HTML, developers can use JS, both work interchangeably Incremental: drop it into an existing site without rewriting or compiling anything If you have a free hour, give it a try! Play around with it, and let me know what you think. It's 100% free and open source under MIT license and I'm looking to polish up any rough edges before letting developers know about it.

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
