Windows System 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!

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.

This course covers the core of TCP/IP network programming required for online game development, with a practical, hands-on focus. You will learn step by step, starting with the basic principles of sockets and progressing through client-server architecture design to implementing a game framework using a self-developed network library. Topics covered: Basic network concepts and how TCP/IP works TCP programming using the Socket API Packet protocol design and implementation of transmission structures Development of a client/server-based game framework Optimization and practical tips needed for actual online game development Notes: The course is conducted on Windows using Visual Studio. Although it uses the standard bsd socket API, there are slight differences from Unix-based operating systems. IOCP and Overlapped I/O are not covered.

You can learn about the basic structure and operating principles of computer hardware, design methods, and OS, and acquire the knowledge necessary to create good programs.

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 will guide you through the complexities of the Linux operating system, from a strong understanding of the Linux kernel to invoking system calls, process management, and file operations. You will also learn threading and interprocess communication techniques.

The author of "Learning the Structure and Principles of the Linux Kernel Through Debugging" provides a proper explanation of the core concepts of 'Interrupt Bottom Halves' in the latest Linux kernel (v6.1), which is most widely used in system software.

Many people use Docker, but few understand its underlying principles. Without understanding these principles, you can only rely on searching for answers when problems arise, rather than solving them yourself. The essence of Docker lies in the operating system. This course is not a superficial overview of memorizing a few commands; it delves deep into the inner workings of the operating system that makes up Docker. Once the internal structure becomes visible, Docker is no longer difficult.

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

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."

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

This course is a “Core Practical Linux” course designed not only for those encountering Linux for the first time, but also for those looking to enhance their Linux skills in practice. It covers the essential fundamentals of Linux, along with only the most frequently used and indispensable features from the perspective of a backend developer in the field.

✅ Out of the entire series (1) ~ (7), (5) operating system, user interface, database ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

The author of "Learning the Structure and Principles of the Linux Kernel Through Debugging" provides a thorough explanation of the core interrupt concepts of the latest Linux kernel (v6.1), which are most widely used in system software.

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

A course where you understand core operating system concepts and train to explain them verbally for interviews.

This course is provided for those who have completed the 'Becoming a CS Major by Memorizing Broadly and Shallowly' course to study operating systems in greater depth.

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.

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

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.
