Astroterm is a terminal-based star map application written in C. It renders the real-time positions of stars, planets, the Moon, and constellation figures using ASCII or Unicode characters. The system computes celestial positions from the Yale Bright Star Catalog, Keplerian orbital elements, and user-specified date/time and location (latitude/longitude or city name). It projects the visible sky onto the terminal via a stereographic projection and uses ncurses for display and input. The build system is Meson with Ninja, supporting Linux, macOS, and Windows. The codebase is well-structured into separate modules for astronomy calculations (astro.c), coordinate transforms (coord.c), terminal rendering (drawing.c, term.c), and data parsing (parse_BSC5.c, city.c). It includes comprehensive unit tests using Unity and CI via GitHub Actions. The application is highly configurable through command-line arguments and demonstrates strong craftsmanship in astronomical computations and terminal graphics.
Gitlogue is a terminal-based Git history visualizer that replays commits as a cinematic typing animation with syntax highlighting. It loads a local Git repository, extracts diffs, and renders the changes character by character in a split-pane terminal interface (ratatui). The core architecture is a monolithic Rust binary using clap for CLI, git2 for Git operations, tree-sitter for syntax highlighting across 32 languages, and crossterm for terminal I/O. It supports multiple playback modes (random, chronological, watch) and includes a configuration system, 17 built-in themes, and a custom animation engine with step-based simulation and checkpoint/restore. Notable reusable components include the SelectableParagraph widget (isolated ratatui component for text selection and dimming) and the Theme system (extensible struct with ~40 named colors). The codebase is well-structured but exhibits moderate technical drift risk due to heavy tree-sitter dependency chain, rapid feature growth, and potential staleness with some language grammare updates. CI/CD is active but the release workflow is manual. Overall, gitlogue is a solid, professional terminal application that effectively delivers its claimed functionality.
Aerial Views is an Android TV screensaver (DreamService) that plays aerial videos and photos from multiple sources—Apple, Amazon, community feeds, local storage, Samba, WebDAV, Immich, Nextcloud Memories, and custom feeds. It provides a rich overlay system (clock, date, weather, metadata, now-playing, countdown, message API) and supports hardware vendor integrations (Projectivy, Philips TVs). The architecture follows a provider pattern with a central ScreenController orchestrating playback, overlays, and services. The codebase is actively maintained with extensive internationalization, unit tests, and CI/CD. While the provider abstractions are clean and extendable, the ScreenController is large and tightly coupled, and the app has moderate technical drift (deprecated APIs, unusual compileSdk 37). Overall it's a well-engineered, feature-complete application for its niche.
This repository is a collection of shell scripts for installing, upgrading, and managing MagicMirror², an open-source smart mirror platform. The scripts automate the setup of Node.js, npm, pm2, and the MagicMirror application on Raspberry Pi and other Linux systems, as well as macOS. They handle tasks such as initial installation, version upgrades, pm2 process management, screensaver disabling, disk cleanup, and switching to browser-over-server mode. The scripts are designed to be executed via curl pipe to bash, ensuring users always run the latest version. While primarily operational, the cleanup.sh script stands out as a well-structured, reusable utility for reclaiming disk space on any system.
