Bestseller 『Study Computer Architecture + Operating Systems on Your Own』 author's free lecture. A collection of computer architecture and operating systems books that developers must know.

Build a hands-on AWS environment with Terraform and learn Zabbix 8’s new features and practical monitoring operations through exercises in fault detection, Slack notifications, and recovery. Store JSON values using Zabbix 8’s Native JSON, then split out the required values with Dependent items and JSONPath. Organize the display columns for recent data and the problem overview, and compare metrics using scatter plots and inverted graph axes. Export the completed Dashboard as YAML and import it again. This course also covers the Server, Agent 2, Item, and Trigger components required for existing Zabbix operations, along with problems and recovery, Slack notifications, maintenance, official MySQL and Redis templates, and Web scenarios. Create and recover CPU, disk, Apache, and HTTP problems yourself to connect the entire workflow. Create and clean up the AWS hands-on environment with Terraform. Follow the actual sequence: saving configuration files, running fmt, init, validate, and plan, applying the saved plan, connecting via SSH, checking the state, and cleaning up the practice resources.

This course is provided for those who have completed the 'Becoming a CS Major by Memorizing Broadly and Shallowly' course to study operating systems in greater depth.

This is a hands-on course where you'll build an AI-based autonomous driving car using Raspberry Pi and various sensors.

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.

Many people use Docker, but few understand its underlying principles. Without understanding these principles, you can only rely on searching for answers when problems arise, rather than solving them yourself. The essence of Docker lies in the operating system. This course is not a superficial overview of memorizing a few commands; it delves deep into the inner workings of the operating system that makes up Docker. Once the internal structure becomes visible, Docker is no longer difficult.

A course where you understand core operating system concepts and train to explain them verbally for interviews.

Instead of theory and memorization, you will naturally master 50 basic Linux commands through practice-oriented learning where you type and execute them yourself. With 95% of the entire course dedicated to hands-on practice, you can gain muscle memory for essential practical functions such as file management, permission settings, and process control. The goal is not to memorize commands, but to become familiar with Linux.

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.
