Linux System Programming - Theory and Practice

If you study the main concepts of Linux, you can handle Linux more easily and more powerfully. I hope you build a solid foundation from the beginning!! :D

You know what Linux is and have learned some basic usage methods, but do you want to use the Linux shell better? Do you need to write Linux shell scripts? Well, it's time to learn Linux shell scripts!

This is a course on Linux command line tools. We will carefully select frequently used tools and teach you about their core functions and frequently used options. And we will teach you how to use them in practice. If you use various Linux tools well, Linux will become easier. And you will understand and handle Linux better :)

The ultimate goal of this course is to go beyond programming using IPC tools and to "develop the ability to appropriately select and design/implement IPC tools that fit software requirements."

This is a concept-focused lecture for beginners who are new to Kubernetes. It explains step-by-step from the background of virtualization technology to Kubernetes components, structure, and operating principles. You can easily understand Kubernetes concepts and operating principles even without hands-on practice.

This course will guide you through the complexities of the Linux operating system, from a strong understanding of the Linux kernel to invoking system calls, process management, and file operations. You will also learn threading and interprocess communication techniques.

The ultimate goal of this course is to go beyond programming using IPC tools and to "develop the ability to appropriately select and design/implement IPC tools that fit software requirements."

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

✅ Out of the entire series (1) ~ (7), (5) operating system, user interface, database ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

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.

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.

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

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.

Creating an application on Linux (Ubuntu OS). (Cross-platform application development)

We will create a remote development environment using VS Code and extensions, and learn about WSL and code-server, a VS Code used on the web.

You can't just let the server you worked so hard to build rot away in a development environment. This lecture will teach you how to operate a server that can be accessed from outside using AWS.

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.

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.

I've created a 'Linux Introduction' course that even non-majors can easily understand and apply immediately in real-world situations!
