This project is a cross-platform terminal emulator that functions as a graphical frontend for command line shells. It operates by managing shell processes through a pseudoterminal emulation layer, capturing raw character streams to display them within a native desktop windowing environment. The application distinguishes itself through a specialized rendering engine that simulates the visual characteristics of vintage cathode ray tube hardware. By utilizing fragment shaders, it applies real-time effects such as scanlines, screen curvature, and phosphor glow directly to the terminal output. Use

This project is a cross-platform messaging client that implements a secure, real-time communication protocol. It provides a comprehensive development toolkit, including a database library and messaging SDK, which allows for the creation of custom messaging applications that maintain synchronized state across multiple devices. The core architecture relies on an asynchronous event-driven model to ensure responsive performance while managing persistent local database synchronization with server-side state. The client distinguishes itself through a robust end-to-end encryption layer that supports
