This course is designed to guide you through the essentials of Python, a language renowned for its simplicity and power. Immerse yourself in the exciting world of programming with our Basic Python course.

This course contains only the essential content about C, the basic language of all languages. It is recommended for those who are learning C for the first time.

This course covers the latest data structures and algorithms used in representative open sources such as Linux.

You can understand assembly code, backtrace functions, and understand the internal structure of gdb, which traces processes. You also cover the kernel's debugging tools.

This course combines topic-specific theory and programming practice to maximize learning effectiveness.

From the fundamentals of systems engineering to security setup, this course will guide you along the way.

In this course, you will learn how to have a free Linux server worth 20,000 won per month, how to use it, and how to utilize it.

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 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.

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

This is a 'Practical Linux Troubleshooting Course' where you analyze and solve problems together with generative AI, based on a Docker practice environment that reproduces 5 representative failures that occur in actual Linux operating environments. Even those who were overwhelmed about where to start examining problems can learn the problem-solving approach and thought process of field engineers through AI guidance.

We'll teach you essential Windows System programming skills for developing games and applications for Windows.

Learn systematically from the basic usage to the advanced features of Zabbix, an essential tool for effective monitoring of IT infrastructure. We offer the opportunity to grow into a monitoring expert using Zabbix through real-world application examples.

This course proceeds in stages, similar to the actual work, by learning and applying the necessary knowledge while configuring the infrastructure.

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.

This course puts an end to operational vulnerabilities in Linux servers caused by incorrect permissions. Completely master file and directory permission control based on real-world practical standards.

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.

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.
