Sythos Barcode Universal is an open-source MIT JavaScript/TypeScript SDK for generating, detecting, decoding, and rendering 1D and 2D barcodes. It has zero runtime dependencies and runs in browsers, Web Workers, and Node.js or Bun. The repository ships readable source, ESM/IIFE bundles, and documentation covering the API, formats, image and camera workflows, examples, and platform guides.
Meet Cordiale: a resource-conscious native desktop client for Grappa, built with Rust and Slint. It speaks Grappa's REST and Phoenix Channels/WebSocket protocol—not raw IRC—so you can chat without hauling a whole browser engine to the tavern. The GUI is still waiting for its first live-server night out. For the Grappa-IRC backstory, visit vjt/grappa-irc.
CVV Dashboard is a custom integration and a Lovelace card for Home Assistant. It reads ClasseViva account data and shows grades, averages, notices, agenda items, notes, report cards, and homework. It creates four Home Assistant calendars for each student.
