We will explain the basic structure of what Linux is, learn how to handle the shell, and learn to gain a basic understanding of Linux networks.

Linux, the most widely used operating system for servers worldwide. This is a story about the basic commands of CLI (Command Line Interface), the first step to freely handling Linux, and shell scripts created by combining those commands. This lecture resolves the questions and concerns that anyone interested in Linux would have had at the beginning.

This course focuses on solving the problem of getting stuck in interviews and practical work due to a lack of understanding of why certain structures and configurations are necessary, rather than just teaching how to configure NGINX. Based on experience evaluating numerous candidates as an interviewer for companies like Naver, Kakao, and Toss, I explain how to describe and utilize NGINX from the perspectives of performance, scalability, and operations through hands-on practice. The core of this course is to help you develop a mindset capable of tracing traffic flow and troubleshooting problems, rather than just memorizing configuration values.

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.

Through this course, you will gain experience deploying front-end and back-end projects. You will also gain basic knowledge about Linux and networks while deploying projects!

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.

I have created a 'Linux for Beginners' course that is easy for non-majors to understand and can be applied in practice immediately!

To those of you hesitating whether to study Linux shell scripting, I will tell you just one thing. Do you want to handle Linux coolly like a hacker? Can you imagine a hacker who doesn't know shell scripting? Then start right now!

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.

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

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.

Build a local LLM with RAG-based Q&A system in just 2 hours of practice using Docker + ollama + R2R framework. (Applicable for internal/in-house Q&A systems, personal portfolios, AI-enhanced work productivity, and even commercial services)

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.
