Open Source Assembly Education Software for Mac

os-tutorial is an open source educational project by cfenollosa that teaches the basics of building an operating system from scratch. The repository provides step-by-step lessons starting with bootloaders and moving through kernel development, interrupts, memory management, and system calls. Each tutorial is accompanied by clear explanations, code examples, and references to deepen understanding. The project uses x86 assembly and C to illustrate concepts, making it accessible to students and hobbyists interested in low-level programming. By compiling and running the examples with tools like QEMU, learners gain hands-on experience with OS fundamentals. With its structured lessons and approachable explanations, the repository has become a widely recommended resource for operating system beginners.

Comprehensive Rust is an open source training course developed by Google to provide a complete introduction to the Rust programming language. Originally created for Google engineers, it has since been released publicly for the broader developer community. The course is structured into modular lessons that cover the fundamentals of Rust, including ownership, lifetimes, traits, generics, and error handling, before progressing to advanced topics like concurrency, async programming, unsafe Rust, and FFI. It is designed to be taught in classroom settings but can also be followed independently, making it useful both for structured training and self-study. The materials are presented in a slide-based format with accompanying examples and hands-on exercises to reinforce key concepts. By offering an accessible yet thorough introduction, the course helps learners gain practical experience with Rust while building a strong understanding of its unique safety and performance guarantees.

This project provides a step-by-step educational guide on building a simple operating system kernel entirely from scratch, specifically targeting the Raspberry Pi 3. The operating system, referred to as RPi OS, is inspired by the Linux kernel but remains intentionally minimal to focus on clarity and teaching fundamental OS concepts. Each lesson introduces a kernel feature and demonstrates its implementation within RPi OS, followed by a comparison to how the same concept is realized in the Linux kernel. The repository is structured so that every lesson corresponds to a snapshot of the source code at that stage, making it easier for learners to follow the progression of kernel development. The design of the lessons emphasizes gradual learning, allowing readers without prior OS development experience to understand kernel internals. The project is still under active development and encourages community contributions to expand its lessons and improve its content.

MuOS is a Operating System for x86-compatible hardware.

Nemesis is a tiny real time operating system kernel based on x86 PCs. Its main purpose is to serve as a simple but realistic example of an real time OS kernel running on real hardware..the purpose of this is that it can be embedded in small devices lik

Oso32 (Otro sistema operativo de 32 bits) es un sistema operativo que funciona en el modo protegido del i80386. Está basado en el Oso original desarrollado por Juan Piernas Cánovas de la Universidad de Murcia. Oso32 surgió con motivo de unas prácticas para la asignatura de Desarrollo y Estructura Interna de un Sistema Operativo (DEISO) de la Universidad de Murcia. Las prácticas consistían en portar el actual sistema operativo (OSO) que funcionaba únicamente en el modo real (16bits) para que aprovechara las capacidades que proporcionan los procesadores a partir del 386 en cuanto a protección y acceso a memoria. El código fuente del Oso32 ha sido liberado bajo licencia GNU General Public License v2 (GPLv2) ya que hace uso de un controlador de disquetera escrito para FreeDOS bajo dicha licencia.

Linux TiTan is yet another Linux Distribution that is divided into 3 parts , the main system including packages compiled by us , a security system and a desktop environment developed using java . Goal : Security , Speed , Portability

This is a short simple boot-able program that animates some Lissajous figures. It can only run when the computer contains Bios, and when the computer is booted. The complete source code is here as an .asm file which can be compiled instantly with the Fasmw compiler. It has an interesting way of switching the computer into 64 bit Long mode. It actually switches the computer back and forth between 16 bit and 64 bit mode, easily, with an interesting technique.
