For Everyone! Essential Introduction to Linux Command Line

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

The curriculum was created with commands that actual developers use. It does not cover complex concepts related to OS installation or management. You can quickly learn the basics of Linux usage in 2 hours.

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.

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.

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.

This course is Part 3 of the Full Stack lecture series, designed to help you solidly master the latest server technologies and Docker. The course is structured to enable you to practically incorporate Docker into your tech stack by meticulously testing Docker's various options, learning related technologies such as Linux that are necessary for understanding Docker, and building actual complex services.

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.

Learn essential Linux knowledge that every developer should know, even if they're not a DevOps or Linux expert. The class will be hands-on and practice-oriented.

This lecture will teach you the basic commands required for performance analysis of Linux servers, how to use the tcpdump command to solve network problems, and troubleshooting methods based on cases. Through this lecture, you will be able to solve various performance problems that occur on Linux servers.

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

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.

✅ 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

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

A course that helps you understand core operating system concepts and practice explaining them verbally in interviews

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.

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.

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.

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