Headline: Master OS Development with QEMU, Assembly, and C in "Build an x86 Operating System From Scratch"

🚀 Course Description:

Embark on a journey to demystify the inner workings of operating systems by developing your very own from scratch! With a focus on practical application, this course not only delves into the theoretical aspects of OS design but also provides you with the tools and knowledge to build a fully functional 300-line mini OS.

What You'll Learn:

• OS Foundations: Gain a solid understanding of operating system concepts, from CPU boot processes to system call interfaces.

• Core Components: Dive into hardware and software interactions, including scheduling, interrupt handling, timers, and memory management (including paging).

• Hands-On Experience: Translate abstract concepts into tangible skills by writing code and seeing your operating system come to life.

📖 Why This Course?

I've been in your shoes before—struggling to grasp OS theory from textbooks alone. The lack of a practical reference point made learning difficult. That's why I'm offering this course: to provide you with a live example to experiment with and understand the practical aspects of an operating system, something I wish I had when I was learning.

🎓 Course Outline:

• Introduction to OS concepts and architecture
• Setting up your development environment with QEMU virtualization software
• Writing the bootloader and kernel in x86 assembly
• Developing essential system components such as interrupt handlers, scheduler, and file I/O
• Implementing advanced features like memory management, paging, and system calls

🛠️ Tools and Technologies:

• QEMU: A versatile and feature-rich open-source machine emulator and virtualizer.
• GCC and NASM: Compilers for the C language and Netwide Assembler, respectively.
• C programming language: The backbone of system-level development.

👥 Community & Support:

• Access to source code files upon registration.
• Regular Q&A sessions via Zoom on weekends (book your slot!).
• A community of like-minded learners and enthusiasts.

🎉 Future Prospects:

Success in this course paves the way for advanced topics, including a comprehensive exploration of the Linux kernel source code (v0.11.0). Keep an eye out for upcoming courses to deepen your system programming expertise!
