Windows API hooks that will change your life if you understand them

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 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.

Design a modern 3-tier web service with AI and develop it using only "Vibe Coding," then deploy it to an AWS environment to complete a fully functional production service! We have included the entire sequence of configuration processes so you can experience core AWS services used in the industry—such as Amplify, CloudFront, ALB, EC2, S3, and RDS—in a single workflow.

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!

This course is designed to guide those who have completed the "Mastering Core Network Theory through Memorization: Basic Course" to understand more advanced theories. It covers deeper concepts such as NAT technology, which is the operating principle of internet routers, as well as load balancing system principles and VPN technology principles. The goal of this lecture is also to finish by "memorizing" it all! You can do it!

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

Anyone who is a C/C++ developer can get started. You can quickly learn MFC Windows programming by selecting only the core. We also provide a 1200-page textbook.

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!

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.

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.

Based on an understanding of Reflection and Annotations, it helps you clearly understand how the Spring framework operates!

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++!

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

Starting with java.io, you can learn how to develop high-performance input/output systems based on NIO and NIO.2. Most importantly, the moment you master file I/O, we'll enable you to master high-performance server development as a bonus!

It covers just two things properly: object-oriented programming and the JVM! Plus, it throws in linked-list-based linear data structures.

For those aspiring to be Java-based Spring backend developers, to easily secure a job, we learn Java properly! Rigorously!

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!

This book contains only the essential techniques for those developing Windows OS-only applications using MFC.

This lecture covers how to properly implement a linked list-based linear data structure using C language. You can understand the structure of the DB as well as the linked list at once.

This lecture comprehensively organizes the content that would be good for those who want to get a job as a new Spring Java backend developer, especially those who are about to have an interview.

Metasploit Definition A tool that allows you to use known vulnerability attacks with CVE numbering, a mock hacking test tool that helps make hacking easier.

This lecture analyzes various protection techniques in the Linux kernel, methods to bypass them, and various vulnerabilities. Practical examples are provided for each lecture.

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.

**"Digital Forensic Techniques by Byte Detective: Evidence Collection and Securing"** is a course focused on how to collect and preserve digital evidence required in cases of cybercrime, internal information leakage, and security incidents. From the basic concepts of digital forensics to the principles of evidence collection, maintaining integrity, and legal procedures for securing evidence, this course explains everything through case studies and procedural steps so that even beginners can understand. You can systematically learn the forensic mindset and core concepts of securing evidence that are essential to know before using professional analysis tools.
