unsafehttp – tiny web server from scratch in C, running on an orange pi
Hey HN, I wanted to get more familiar with C programming, *nix socket programming and C compilation, so I wrote this "web" ""server"". It's running on a tiny SBC in my office, and there's as little as possible between you and it. Happy for you to try and break it, hopefully with something more interesting than a DoS though :) Please let me know if you find any issues.
unsafehttp – tiny web server from scratch in C, running on an orange pi launched on August 16, 2025 with 87 votes, #418 of 8,530 launches that month and more than 95% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
Unsafehttp is a minimal web server written in C from scratch, designed to run on single-board computers like the Orange Pi. Built as a learning project to explore C programming, Unix socket programming, and compilation, it prioritizes simplicity with minimal layers between requests and responses. The creator invites users to test its functionality and report any issues discovered.

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!
