How to Make the Most of a Mini PC Without Any Programming Experience – Build Your Own Home Server

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.

Sensor and vision AI can feel daunting, from data collection to deployment. Drawing on hands-on troubleshooting experience, this course uses illustrations and practical exercises to guide you toward a working result. This is a practical embedded AI development course you can start without math. Using Arduino Nano BLE 33 and Nicla Vision boards, you’ll build and deploy gesture recognition and image classification models yourself. With the no-code Edge Impulse platform, you’ll gain hands-on experience with the entire process, from data collection to deploying deep learning models. Practical troubleshooting and performance improvement tips will help you develop real-world edge device development skills.

This is a DevOps course based on practical experience in Silicon Valley. It goes beyond theory to cover content that can be applied immediately in the field. You will learn how to develop using Generative AI (Vibe Coding), set up CI/CD tools in a Kubernetes environment, and implement strategies to keep operating costs at $0. We will cover configuring a production environment without additional costs by running DB, Redis, S3, and batch jobs inside Kubernetes, and you will master building automated pipelines using GitHub Webhooks and Jenkins through hands-on projects.

This course covers how to use Linux. The part that beginners find particularly difficult is how to control the computer using commands. This course covers the most common rules that beginners need to use commands.

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

“Security solutions are numerous, but why can't threats still be stopped?” “Tools are overflowing but not interconnected, Warnings are pouring in, but aren't you missing what's truly important?” Now is the era when not just simple defense, but proactive and active 'action-oriented security' is needed. At its core is Microsoft's unified security. From ID, devices, apps, cloud, to infrastructure, connecting all security elements into one, AI detects, assesses, and eliminates threats in real time. Microsoft Security is not just a 'defense solution' but a real-time response system that protects the entire enterprise. Now, don't regret it after an incident occurs. Start security 'in advance', 'proactively', and 'smartly' with the Microsoft unified security platform, starting today.

Instead of long and boring theories, you can learn them one by one through short practical exercises, and as you flesh them out one by one, you will soon be able to experience the overall architecture composition.

This is a process for completing IoT products without complex coding, using the Vibe Coding methodology powered by AI agents. You can experience the entire product development cycle in a condensed format—from embedded hardware control and AI vision recognition to PCB design, 3D printing, and web/app service development—allowing you to launch functional, commercial-grade IoT devices.

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.

Systematically learn Docker, a core tool for container-based application deployment, from the basics to practical application. Starting with Docker's basic structure and commands, you will develop practical skills that can be immediately applied to real-world tasks, including container packaging in microservices architecture environments, deployment automation, and standardization of production environments.

Beyond traditional Jenkins-based CI/CD, this course also covers GitOps deployments using ArgoCD. You will design and implement CI/CD and GitOps deployment strategies for dev, staging, and production environments by combining Jenkins and ArgoCD. You will work with both push-based Jenkins and pull-based ArgoCD, directly comparing the two approaches on the same cluster to build a practical hybrid deployment pipeline. You will practice essential deployment techniques for operations, including Canary, Blue-Green, RBAC, approval procedures, incident response, and automatic rollback.
