What it is, why it exists, who it's for.

LinuxLab is a platform of interactive tutorials for infrastructure and systems skills. Three tutorials are currently open: Linux and networking, Terraform with a sandbox on LocalStack, and Git with GitHub Actions.

Each lesson opens an isolated sandbox with a real environment: you run commands, watch the system state change (kernel, Terraform plan, Git objects, depending on the topic), and each step is checked automatically.

This is not a video course, and not a static tutorial. It's a tool where practice and verification happen at the same time. Open it, type, see the result, continue.

The project came from a personal observation: I got tired of video courses I'd forget in a week and VMs I never set up. I wanted something in between, real enough to stick, simple enough that you're not fighting the environment.
