  Roundtable – Survey fraud and bot detection API2024 · ▲21

  Hi HN, we're Mayank and Matt of Roundtable (https:&#x2F;&#x2F;www.roundtable.ai). We launched our Survey Simulator as part of YC S23 (see Launch HN: https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=36865625), and ultimately decided to pivot because we couldn't convince users to trust our results and our value proposition wasn't clear. We conducted tons of user discovery interviews, and a lot of big players talked about the pain of manual QC and bot detection. We launched a survey fraud and bot detection API (Alias; docs.roundtable.ai) that determines whether a bot is answering your survey…

  I spent 6 years building a ridiculous wooden pixel display▲1,145

  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:&#x2F;&#x2F;kilopx.com&#x2F;

  Kitten TTS – 25MB CPU-Only, Open-Source TTS Model▲1,003

  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 curious about spherical helix, ended up making this visualization▲865

  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:&#x2F;&#x2F;visualrambling.space&#x2F;moving-objects-in-3d&#x2F; feel free to visit and let me know what you think!

  The current sky at your approximate location, as a CSS gradient▲788

  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.
