Guidance only
You type. We explain.
Nothing on this site executes commands. You practice on Windows (WSL), macOS, or Linux — the same kind of machine data and AI work actually uses.
Data Engineering · Foundations
Learn the craft from the terminal up.
A free roadmap for Data Engineering and AI. This site guides — it never runs commands for you. The Linux module is written for people who have never opened a terminal.
A path, not a dump
Roadmap first
Foundations (Linux, Python, SQL, Git) then Data Engineering. Linux is ready. The rest is coming, in order.
Made for beginners
No assumed terminal skill
Lessons start at “what is a prompt?” and end at logs, pipes, disk, and SSH — the weekly skills of DE and AI work.
Module 01
Linux fundamentals
About 6–8 hours, split across sessions. Set up a real terminal, learn the filesystem, read logs, peek at CSVs, and finish with a local lab: First data shift.
