WinDynamicDesktop is a Windows desktop application that replicates the macOS Mojave Dynamic Desktop feature, automatically changing the desktop wallpaper based on the time of day. Built with WinForms and .NET, it determines sunrise/sunset times using the device's location (via Windows location service or a geocoding API) and supports multiple monitors, lock screen synchronization, theme importing (from ZIP, JSON, or .ddw files), and localized translations across 50+ languages. The architecture includes a platform abstraction layer (DesktopHelper/UwpHelper for standard and UWP deployments), COM wrappers for wallpaper and power settings, SkiaSharp-based theme preview rendering, and an event-driven scheduler that responds to system events. It also features a PowerShell scripting interface for advanced customization, automatic updates via GitHub releases, and a config migration system for backward compatibility. The codebase is well-structured with clear separation of concerns, though it relies on external APIs (LocationIQ, POEditor) and Windows-specific COM interfaces, which introduce maintenance risk. The repository includes unit tests (sunrise calculations, system integration), CI/CD pipelines, and packaging scripts for installer and store distribution.
term39 is a cross-platform terminal multiplexer and emulator built in Rust, featuring a retro MS-DOS aesthetic. It provides a full-screen text interface with window management (drag, resize, minimize, maximize, auto-tiling), terminal emulation via VTE ANSI parsing and PTY integration, session persistence through a Unix daemon, a lockscreen with OS-level authentication (PAM, macOS DS, Windows Security, PIN), and an optional Linux framebuffer backend for direct console rendering. The application supports multiple platforms including Linux, macOS, Windows, FreeBSD, NetBSD, OpenBSD, and Android/Termux, with feature-gated builds via Cargo features. The architecture is modular: an event loop drives input handling (keyboard, mouse) and rendering through a `RenderBackend` trait that abstracts terminal (crossterm) and framebuffer backends. The UI is composed of widgets (top bar, battery, network, system menu) and dialogs (config, prompt, toast, info). Terminal state is managed by `TerminalGrid` and `TerminalEmulator`, with ANSI escape sequences parsed by `AnsiHandler`. Session persistence uses a client/daemon pattern over Unix domain sockets, allowing windows to be detached and reattached. The lockscreen supports multiple authentication backends via a factory pattern. While the codebase is feature-rich and well-structured in many areas, it exhibits some technical drift: dead code artifacts (e.g., a disabled restore line in main.rs), heavy use of `#[allow(dead_code)]`, platform-specific code duplication, and unsafe operations in forking and signal handling. The rapid version history (0.1.0 to 1.6.0 in about a year) suggests fast iteration, which may have introduced some technical debt. Nonetheless, the project demonstrates strong engineering in its abstraction layers, widget system, and cross-platform support.
