ReactOS is an open-source operating system designed to be binary compatible with Windows applications and drivers. It consists of a low-level system kernel that manages hardware resources and a binary compatibility layer that enables the execution of software designed for the Windows binary interface. The project implements a cross-platform build system and toolchain for compiling and deploying bootable operating system images across different hardware architectures. This includes the use of cross-compilation toolchains and a hardware-abstraction layer to support various processor and motherb

This project is a freestanding kernel written in Rust that boots on x86 hardware without a standard library. It serves as a low-level system implementation focusing on the creation of a bare metal operating system. The system implements a bootable disk image toolchain that transforms source code into binaries compatible with a bootloader. It features a custom memory allocator for dynamic memory management and an x86 kernel implementation that includes paging, interrupt handling, and VGA text mode. The project covers several core capability areas, including low-level memory management through

macfuse is a framework for implementing custom file systems in user space. It utilizes a macOS kernel extension to bridge the operating system kernel's virtual file system layer to a user-process daemon. This project allows the implementation of file system logic outside of the kernel to improve system stability and simplify development. It enables the mapping of remote data, network resources, or memory to a local folder so they can be accessed through standard system interfaces. The framework supports the development of cross-platform storage by providing a portable interface for consisten

WinFSP is a framework for implementing custom file systems on Windows. It enables the creation of user-mode file systems that appear as standard disk drives or network shares to the operating system, allowing developers to implement file system logic in user space via a proxy architecture that avoids the need for custom kernel code. A primary differentiator is its FUSE compatibility layer, which maps POSIX-based file system calls to native Windows requests. This allows existing file systems written for the FUSE API to be ported to Windows and Cygwin environments. The project covers a wide ra

This project consists of technical instructional guides and a structured computer science curriculum designed to teach the construction of a full computing stack from transistors up to a web browser. It provides a 12-week educational course that covers the fundamental domains of computer architecture and digital logic design. The curriculum is distinguished by its first-principles approach, guiding the learner through the engineering of CPUs, FPGAs, and PCBs using digital logic and hardware description languages. It includes specific syllabi for building a hardware design, a TCP/IP network st

SSHFS-Win is a Windows implementation of SSHFS that mounts remote directories over SSH as local Windows drives, enabling seamless file access as if they were local network drives. It provides both command-line and graphical interfaces for creating, managing, and disconnecting SSHFS mounts, supporting password or SSH key authentication with optional credential storage in the Windows Credential Manager. The project extends beyond basic SSH mounting to support a wide range of remote file access scenarios, including mounting cloud storage services like Azure Blob or Amazon S3, distributed POSIX f

Dokan is a user-mode file system library for Windows that allows applications to create custom file systems accessible as normal Windows volumes without writing kernel-mode device drivers. It provides a FUSE compatibility layer that maps FUSE operations to Dokan callbacks, enabling existing FUSE-based file systems to run natively on Windows by rebuilding the source code with Cygwin or MinGW. The library exposes its file system API through language-specific wrappers for C, .NET, Java, Delphi, Ruby, and Python, supporting cross-language file system development. It handles file operations throug

Acest proiect este un framework educațional și un set de instrumente conceput pentru dezvoltarea și testarea kernel-urilor de sistem de operare. Oferă un mediu structurat pentru implementarea primitivelor fundamentale de sistem, inclusiv gestionarea memoriei virtuale, programarea preemptivă a proceselor și organizarea sistemului de fișiere, folosind Rust și C. Framework-ul este orientat în mod specific către arhitecturile RISC-V și x86, servind drept laborator pentru învățarea modului de construire a software-ului de bază al sistemului de la zero. Proiectul se distinge prin suportul atât pentru implementarea pe bare-metal, cât și pentru emularea hardware, permițând dezvoltatorilor să valideze logica kernel-ului pe hardware fizic sau în medii simulate. Include un toolchain complet de build care gestionează compilarea cross-arhitectură și inițializarea firmware-ului, asigurând că kernel-ul poate fi corect bootstrapat și executat pe diferite platforme țintă. Sistemul acoperă o gamă largă de capabilități de nivel scăzut, inclusiv straturi de abstractizare hardware care decuplează logica sistemului de design-urile specifice ale procesoarelor și interfețe de apeluri de sistem care gestionează limita dintre aplicațiile user-space și serviciile kernel-ului. De asemenea, încorporează funcții de observabilitate, cum ar fi logarea la runtime și monitorizarea execuției, pentru a asista la analiza comportamentului sistemului în timpul dezvoltării.
