Windows System Programming

It seems the mainstream graphics API has shifted from D3D11 to D3D12. D3D12 supports attractive features but has a steep learning curve. However, I believe that with gradual learning, individuals can also create games using the D3D12 API. Therefore, based on my experience building a game directly with D3D12, I aim to provide the knowledge base needed to challenge D3D12 game programming.

Introduces the knowledge and approaches needed to develop your own engine.

This course covers the core aspects of TCP/IP network programming essential for online game development with a practical focus. You'll learn step by step from the basic principles of sockets to client-server architecture design, and implementation of game frameworks using custom-built network libraries. Topics covered: Basic network concepts and TCP/IP operation principles TCP programming using Socket API Packet protocol design and transmission structure implementation Client/server-based game framework development Optimization and practical tips needed for actual online game development Important notes: The course is conducted on Windows using Visual Studio. While it uses standard BSD socket API, there are slight differences from Unix-based operating systems. IOCP and Overlapped I/O are not covered.

DirectX 12 supports real-time Raytracing, allowing high-quality graphics to be implemented with concise code. However, due to the high barrier to entry, programmers who directly utilize it are rare. Based on experience applying Raytracing to actual games, this course will help you develop your own Raytracing engine.

Let's learn Windows debugging techniques that no one tells you about.

This course continues from D3D12 Programming Basics. After implementing basic rendering features, it explains the features and approach needed for actual engine development using them.

This tutorial introduces how to use Tiled Resources in D3D11/12.

Introduces the purpose and programming method of Mesh Shader, a new feature added in D3D12.

This course provides the basic knowledge needed for those with experience in D3D9/10/11 or OpenGL to adapt to D3D12 programming.

A must-take course for anyone thinking of becoming a Windows programmer! Have you studied C/C+, data structures, and operating system theory? If so, studying system programming is the answer now. Now it's time for practice!

Take the leap from a beginner to an intermediate developer by learning Qt/QML programming skills and the latest technologies through real-world projects.

This course covers the fundamental concepts of operating systems, one of the core subjects in computer science. Operating systems are essential software for efficient resource management and providing user environments in computer systems, and through this course, learners can systematically understand how operating systems work and what components they consist of. Additionally, by learning the structures and functions of various operating systems, students will master the detailed operating principles of operating systems such as processes, memory management, file systems, and disk management, and can solidly build the foundational knowledge necessary for actual development and system utilization. Through this course, learners will gain a comprehensive understanding of operating systems and will be able to have confidence in advanced computer science learning and practical applications.

This lecture teaches the essential OS principles for all developers.

The author of "Learning the Structure and Principles of the Linux Kernel Through Debugging" thoroughly explains the core concepts of processes in the latest Linux kernel (v6.1), which is most widely used in system software.

Are you having trouble using CMake? After taking this course, you too will be a CMake expert.

The author of "Learning the Structure and Principles of the Linux Kernel through Debugging" properly explains the core interrupt concepts of the latest Linux kernel (v6.1), most used in system software.

This is a course provided to those who have completed the course 'Learn broadly and superficially to become a computer science major' so that they can study the operating system in more depth.

A course that helps you understand core operating system concepts and practice explaining them verbally in interviews

Now I can analyze the Linux kernel too! The easiest kernel lecture among Linux kernel lectures.

Bestseller 『Study Computer Architecture + Operating Systems on Your Own』 author's free lecture. A collection of computer architecture and operating systems books that developers must know.

This is the process of refactoring a game engine made with C++ using the DirectX 11 library. It was developed by inferring internal code, allowing you to think about the internal principles of the Unity engine. This is not a project at the level of a rendering program typically covered in academies/lectures. It builds a real game engine incorporating various technologies, from the build system and scripting.

This is the process of creating a game engine using C++, similar to the Unity game engine. It was created by inferring the internal code, and through this, we can think about the internal principles of the Unity engine.

This is Part 1 of a roadmap lecture that concisely organizes the essential computer science (CS knowledge) needed to excel in development and data, in a short period. This lecture has also been used as an in-house lecture at top domestic companies for several years. Based on 20 years of experience in actual practice, from system SW to web, app development, and data science, this lecture systematically yet easily organizes the essential core knowledge needed to excel in development and data.

This course puts an end to Linux server operational vulnerabilities caused by incorrect permissions. Master file and directory permission control based on real-world industry standards.

The author of 'Linux Kernel Structure and Principles Learned Through Debugging' properly explains the core concept of the 'interrupt bottom half' in the latest Linux kernel (v6.1), most used in system software.

Don't practice C in a boring environment, have fun practicing C by building real, usable Windows applications.
