Windows Debugging Tips

GPGPU is no longer an unfamiliar technology. It has long been utilized in various fields such as scientific computation, simulation, and graphics processing, and today, it has established itself as the core foundation that determines the performance of AI technology. In this context, GPU programming skills serve as a powerful tool that expands a developer's capabilities to the next level. Moving beyond CPU-centric development to directly handling large-scale parallel computing means acquiring a new way of problem-solving and broader development possibilities. This course systematically covers CUDA programming—the de facto standard of GPGPU—from the basics to practical application. The curriculum focuses on content that can be immediately applied in practice, including understanding GPU architecture, parallel programming models, memory optimization, and kernel writing. The goal is to reach a level where you can design and implement GPU-based programs on your own after completing the course.

We'll teach you essential Windows System programming skills for developing games and applications for Windows.

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.

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

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

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 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.

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 essential content that C# application developers with 0.5 to 3 years of experience must know.

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

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

What is the biggest obstacle in C++? When I think about it, I think it is CMake. When I first started C++, CMake made it difficult to build even one source file… Let’s break it together. With this lecture, you too can become a CMake Master!

Simply learning C++ is not enough. You can truly see C++ only when you understand "why these syntax rules were created." This course is not just a list of simple syntax. A Microsoft MVP with 30 years of experience and the author of "Do it! Introduction to C Language" explains the structure and philosophy of C++ in depth from the perspective of a language designer. As a result, you will experience a shift in your developer mindset that goes beyond just "friendly explanations."

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 course goes beyond simple grammar explanations and focuses on developing C++ programming skills that can be applied immediately in the field. Throughout my teaching, I have directly addressed common challenges faced by many learners—such as struggling to understand the STL or feeling confused by file handling and exception handling concepts. Based on this experience, I provide step-by-step explanations to ensure even complex concepts are understood easily and clearly. Furthermore, this course is not just about delivering theory; it is structured around: 👉 "Why this concept is necessary" 👉 "How it is used in actual code" 👉 "How it is applied in professional practice"

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.
