In plain words
Axon is a lightweight Python WSGI framework built with only standard library code in 507 lines. It streams files at up to 237MB/s on minimal hardware while keeping memory usage bounded below 225MB. The framework bundles multiple files into multipart streams, supports HTTP range requests, and uses generators for efficient delivery. It is designed for developers who need fast file serving with minimal dependencies and resource consumption.

Quick Links: - PyPI: https://pypi.org/project/axon-api/ - GitHub: https://github.com/b-is-for-build/axon-api - Deployment Script: https://github.com/b-is-for-build/axon-api/blob/master/examp... Axon is a 507-line, pure Python WSGI framework that achieves up to 237MB/s file streaming on $8/month hardware. The key feature is the dynamic bundling of multiple files into a single multipart stream while maintaining bounded memory (<225MB). The implementation saturates CPU before reaching I/O limits. Technical highlights: - Pure Python stdlib implementation (no external dependencies) - HTTP range support for partial content delivery - Generator-based streaming with constant memory usage - Request batching via query parameters - Match statement-based routing (eliminates traversal and probing) - Built-in sanitization and structured logging The benchmarking methodology uses fresh Digital Ocean droplets with reproducible wrk tests across different file sizes. All code and deployment scripts are included.

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.
