What it does
👻 Ephemeral posts 🤝 Bluetooth-based nearby user connections 🎭 Anonymous posting without personal information 🚫🤖 Physical proximity requirement deters AI bots 🔒 No permanent storage prevents AI scraping🧪 Currently in private beta with limited spots
Decentralized microblogging using bluetooth mesh networks
Bluetooth mesh networks form a "Mycelium" of connected devices, letting you share posts with other users nearby without an internet connection. Mycelium is designed with privacy in mind. All posts are anonymous. Your data is stored locally on your device and cannot be accessed by web scrapers or for AI training. Mycelium does not use any addictive algorithms to keep you hooked. There are no likes, and all users are on an equal playingfrom getmycelium.app

Mycelium powers the graph viewer of the Talaria [0] a research model visualization and optimization system, which was used to optimize the efficiency of Apple Foundation Models [1]. Everything works entirely on the client-side in the browser — we provide a rudimentary ONNX loader out of the box, which you can try by dragging model files into our website. It is also simple to define loaders for your own model formats. The library was…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

Would love to hear your thoughts!
