Redox is a POSIX-compliant, microkernel-based operating system written entirely in Rust. By utilizing a memory-safe language for the kernel and all system components, the project eliminates common vulnerabilities such as buffer overflows and use-after-free errors. Its architecture relies on a minimal kernel that manages only essential hardware and process isolation, delegating all other system services to unprivileged user-space processes. The system distinguishes itself through a modular design where hardware drivers and system services run as independent user-space daemons, allowing them to
This project is a tutorial and framework for building a low-level, bare-metal operating system from scratch using the Rust language. It focuses on ARMv8 kernel development specifically for the Raspberry Pi 3, providing the resources necessary to implement a monolithic kernel that runs directly on hardware without an underlying operating system. The project distinguishes itself by providing a complete embedded cross-compilation suite within a containerized environment to ensure consistent builds. It includes a dedicated kernel deployer that uses a serial interface and chainloader to load and b
This project is an X11 window system server that coordinates graphical output and input devices. It functions as a display server, a hardware driver manager for graphics and input modules, and a graphics server capable of rendering directly to a generic framebuffer. The server provides multi-seat display management to isolate input and display devices for different concurrent users. It also implements namespace isolation to separate clients and restrict resource access, preventing interference between different user sessions or processes. The system manages GPU driver integration through dyn
ZealOS هو نظام تشغيل 64-بت مصمم للنشر على الأجهزة المعدنية (bare-metal) وتطوير النواة المخصصة. يوفر بيئة قائمة بذاتها تعمل ضمن نموذج ذاكرة ذي مساحة عنوان واحدة، حيث يتم تنفيذ جميع البرمجيات في مستوى امتياز الحلقة صفر (ring-zero) للقضاء على تبديل السياق وتسهيل التفاعل المباشر مع الأجهزة.

This project is a comprehensive educational framework designed to guide learners through the complexities of systems engineering and low-level software development. It provides structured learning paths that integrate hardware simulation, source code analysis, and project-based exercises to help developers master the foundational concepts of computer architecture, operating systems, and firmware design. The curriculum distinguishes itself by emphasizing direct interaction with system internals, requiring learners to examine and modify existing open-source kernel and driver implementations. By
