The easiest Linux kernel lecture in Korea

I will explain what embedded development is. I will provide a clear explanation of the concept without any vague or abstract descriptions.

An introductory course that lets you experience the entire embedded development process at once—from installing Linux to controlling a robot When you want to get started with embedded systems, it can be overwhelming to know where to begin. This course is designed for those people to experience the entire process at once, starting with a single PC and ending with making a robot move. It covers everything from Linux installation and basic configuration, and preparing a Raspberry Pi, to reading circuit diagrams and datasheets, and practicing basic communication interfaces. Rather than focusing on depth, it focuses on understanding the overall structure.

The author of "Learning the Structure and Principles of the Linux Kernel Through Debugging" provides a thorough explanation of the most advanced kernel memory dump debugging skills used in system software, based on the latest Linux kernel (v6.1).

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.

The author of "Learning the Structure and Principles of the Linux Kernel Through Debugging" will help you firmly grasp the basic concepts of the latest Linux kernel (v6.1), the core of the Linux operating system and the most widely used system software!

Through this lecture, you can systematically learn core concepts such as an overview of readv/writev, understanding struct iovec, utilizing readv, utilizing writev, and performance considerations.

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.

From Theory to the Field: Proving Core Competencies of a Security Expert through Wazuh+ELK SIEM Implementation Design and operate a Threat Hunting system, the core of security monitoring, firsthand. Through hands-on practice based on real-world attack scenarios, transform into a professional security engineer capable of delivering immediate results in the field.

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!
