SilentSuite
End-to-end encrypted sync for calendar, contacts and tasks.
What it does
End-to-end encrypted synchronization for your calendars, contacts and tasks. Integrates with your existing apps so you barely notice it’s there. Open source and zero-knowledge. Everything is encrypted on the client side and the server never has access to your data, even if compromised. Self-host for free or use the hosted service.
Open-source, zero-knowledge calendar, contact, and task sync. Plaintext stays off the server, and encryption keys stay on trusted devices.
End-to-end encrypted sync across web, Android, Apple Calendar, Thunderbird, and self-hosted servers. Everything is encrypted on your device before it syncs. Calendar events, tasks, and contacts stay useful on your devices. The server in the middle only sees changing ciphertext. A calendar invite, one phone number, and a recurring task can reveal more than a profile page. SilentSuite treats those records as private data by default. Most productivity clouds can turn calendars, contacts, and tasks into a profile of your habits, relationships, and intent. SilentSuite syncs encrypted records. The server gets ciphertext, not behavioral material. Big ecosystems make your planning data depend on…from silentsuite.io

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
