MFC Windows Programming - Basics

We delve into how AI coding tools work internally based on 510,000 lines of leaked Claude Code source code. Understand context management, memory processing, and prompt delivery mechanisms, and learn vibe coding practices for applying them to real-world development workflows.

We will help you memorize and finish the encryption technology responsible for the security of the Internet very easily. You can understand the structure and principles of various technologies such as SSL certificates, PKI technology, digital signatures, and public authentication systems.

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.

We have gathered all the essential network theories that those planning to operate services in an AWS environment must know. Through this course, you can understand the principles of how AWS VPC (Virtual Private Cloud), composed of private networks using Private IPs, works and gain a detailed understanding of the roles of services such as ALB and NLB.

This course is for those who want to develop packet analysis programs like Wireshark and various network solutions using the Npcap library.

You will learn the meanings of tokens and context, terms you need to know before using AI services, and why LLMs are called “generative” AI. Through a simple hands-on exercise using Claude for Desktop, you will process unstructured text data into structured data and create a PPT and dashboard. You will learn everything from installing Claude Code to its basic usage, building a foundation for starting vibe coding.

This is a lecture for all non-major beginners who want to become computer science majors by memorizing broadly and shallowly. You can quickly learn what you can learn in essential computer science major subjects such as computer architecture and operating systems. Above all, you can finish it by memorizing it!

Are you lost while learning web development? I'll help you find your own way. Even if you're not from a computer science background, you can understand how web service architecture works through a short 1-hour lecture.

This is a practical project course where you will build a complete web service from planning to deployment using AI coding tools. You will gain hands-on experience with the entire process—including database design, file storage implementation, and service operation—within a Windows environment to acquire practical development skills for the AI era.

This is a C programming course for those who wish to pursue a path as a professional developer rather than just a hobbyist. I recommend this to those who are willing to learn through bitter and rigorous study to reach a sweet destination!

From AWS EC2 backend operations to automatic error fixing, we are revealing the entire development process of Sidabari (https://github.com/cx8537/sidabari), a Claude Code-based automation tool. In this course, we provide all the actual prompts and conversation history used as learning materials, allowing you to experience the entire prompt input process involved in its creation.

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.

You will acquire the skills to develop a security system by learning how to intercept the process in which a specific application calls various API functions. ※Absolutely no abuse!!!

If you have studied the C language thoroughly and studied linear data structures, it is now time to experience the world of object-oriented programming with C++!

From TCP/IP to HTTP! This course is prepared for those who lack basic network theory but hope to understand major-level concepts, even if it means "memorizing" them. You can do it!

We enable you to fundamentally understand and resolve issues where Hangeul appears broken on web pages or in databases, or files contain unknown characters.

We will conduct an in-depth analysis of major domestic security incidents, such as personal information leaks from mobile carriers, the March 20 cyberattack, and the hacking of the Blue House. By examining the causes, damages, and response processes of each incident, we will understand the security threats facing modern organizations and individuals and learn practical prevention and response strategies.

In this lecture, you will learn application-level protocol design techniques and how to develop a high-performance server based on IOCP!

Secrets to Escaping Beginner Status Revealed! We'll properly teach you about Java multithreaded programming and synchronization techniques!

This course summarizes the essential concepts you must know before learning any programming language. Furthermore, by practicing with a dedicated training system, anyone can easily acquire the critical thinking skills necessary for programming.
