PgHook – Docker image that streams PostgreSQL row changes to webhooks
I needed real-time updates in a web UI whenever PostgreSQL table rows change, so I built PgHook. It's a 23 MB Docker image (10.1 MB compressed), .NET9 AOT-compiled, that streams logical replication events and sends them to a configurable webhook. In my setup, the webhook converts events to SignalR messages that push updates to the UI. I know about Debezium but I needed something minimal, and I like playing with csharp.
In plain words
PgHook is a Docker image that captures PostgreSQL row changes using logical replication and streams them to a configurable webhook in real time. Built with .NET9 and compiled ahead-of-time, the image is 23 MB (10.1 MB compressed). It enables web applications to receive live database updates by forwarding replication events to webhooks, which can then trigger UI notifications or other actions. Designed as a minimal alternative to larger solutions.

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.
