By understanding the internal structure of the C language, you can implement faster and more memory-optimized programs.

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

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.

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.

Linux is an operating system widely used on various platforms worldwide, including servers, the cloud, and IoT devices. Through this course, you can enhance your competitiveness in the IT field based on a deep understanding of Linux. Furthermore, by acquiring expertise in open-source technology, you can prepare for the future technological landscape and stand out in a high-demand job market.

This is a C language programming course for those who want to become professional developers rather than hobbyists. I recommend it to those who want to learn by writing and reading and go down a sweet path!

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.

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

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

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

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

This course covers the essential knowledge that every 0.5 to 3-year C# application developer should have.

Learn about Permission, the most fundamental and important concept in Linux. This course provides a solid foundation of basic permission structures, then progressively covers advanced topics including special permissions (Set-UID, Set-GID, Sticky-bit) and ACL (Access Control List) that are essential in real-world practice. Through this course, you will accurately understand permission operation principles and exception cases, and systematically acquire the know-how for safe permission configuration and management in actual server operations. File and directory permission control is the starting point of Linux security. Master the entire process of permission management with this single course.

In this lesson, you will learn how to create an .EXE file. You will also learn how to install an MSSQL database and request data in C#.
