Windows System Programming

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.

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

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.

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.

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 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.

Introduces the knowledge and approaches needed to develop your own 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 'Core Practical Linux' course is designed for those new to Linux, as well as those looking to enhance their practical Linux skills. It covers core basic Linux content and focuses only on essential and frequently used features from a backend developer's perspective.

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.

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

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.

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

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.

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."

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.

Have you learned C++ and Java separately but felt confused about why they were designed differently? This course compares both languages simultaneously, helping you fully understand object-oriented structure, memory, and operational principles. Beyond simple syntax, you will gain a deep understanding through hands-on practice of: ✔ Compilation structures ✔ Memory model differences ✔ Internal workings of inheritance and polymorphism ✔ Virtual tables and JVM architecture Additionally, we provide a 'Python-based code comparison auto-generator tool' to help you visually understand the conversion structure between C++ and Java. We will elevate your skills from simply "using" object-oriented programming to a level where you can "design and explain" it.

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 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.

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

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 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.

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.

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