Crow is a modern C++ microframework for building HTTP and WebSocket services. Designed as a single-header library (or modular headers), it provides a Flask-like routing system with typed URL parameters, a middleware pipeline (global and per-route), built-in JSON parsing and generation, Mustache templating, multipart form handling, static file serving, gzip/deflate compression, and SSL/TLS support. The framework is header-only and leverages C++17/20 features such as std::string_view, std::optional, and constexpr where possible. It includes a comprehensive test suite (Catch2), fuzz testing for security, and extensive documentation via MkDocs and Doxygen. Crow is packaged for multiple platforms (Vcpkg, Homebrew, AUR, Conan, Nixpkgs) and is used in production by several open-source projects. The architecture is event-driven, built on top of Asio (standalone or Boost), with a focus on performance and simplicity. Reusable components include a standalone JSON library, base64 utilities, and a flexible middleware system.
This repository is a comprehensive bare-metal microcontroller programming guide, providing step-by-step examples from minimal firmware to a full embedded web server with a device dashboard. The code targets ARM Cortex-M and RISC-V microcontrollers (STM32, TI TM4C, RP2040, ESP32-C3, nRF52840, etc.) and uses only GCC, a datasheet, and the Mongoose networking library. The architecture is bare-metal, single-threaded with an event loop in the webserver step; it demonstrates direct register manipulation, interrupt handling, UART, SysTick, clock configuration, printf retargeting via newlib syscalls, CMSIS integration, and Ethernet with built-in TCP/IP (MIP). The repository also includes reusable project templates for blinky, CLI, and LittleFS filesystem. Despite being educational, the code is production-quality and follows embedded best practices such as non-blocking timers, hardware abstraction layers (hal.h), and modular startup code.
CyberPanel is a production web-hosting control panel built as a monolithic Django application. It manages websites, DNS, email, databases, FTP, SSL certificates, backups, Docker containers, file access, and server security on OpenLiteSpeed/LiteSpeed servers. The system is installed via shell bootstrap scripts and runs from /usr/local/CyberCP, exposing a web UI, a JSON API, a CLI, and a WebSocket-based SSH terminal. Dozens of Django apps (websiteFunctions, backup, dockerManager, mailServer, dns, databases, filemanager, IncBackups) route requests through ACL checks and plugin pre/post signals into service-specific managers that issue OS-level commands to OpenLiteSpeed, PowerDNS, Postfix/Dovecot, MariaDB, PureFTPd, Docker, restic/rustic, and CloudLinux. The codebase is not a data/research project; it is a full application with operational configuration and hosting metadata as its primary data.
