Short readings that open with the pain, then the analogy, then the term — each paired with an in-browser lab you actually run. No setup, no fluff.
Read · Run · Check
Pick a track. Every lesson is a reading plus a lab with checks.
From your first terraform apply to variables and outputs — declare infrastructure instead of clicking it into existence. 2 lessons live.
Your first Go run through a growing real project — a CLI you keep extending, all the way to concurrency. Lesson 1 live, more on the way.
Open track →Every lesson follows the same rhythm.
A short reading that starts with the pain you already feel, explains it with an analogy, and only then names the formal term.
A simulated terminal right in your browser. Type real commands, edit real files — nothing to install.
Per-step Check buttons verify you actually did it. Nothing is skipped, nothing is hand-waved.
rhash is a small, independent learning project — built by one person who got tired of tutorials that explain the term before the pain.
Lessons are written from official docs, kept incremental, and every lab is tested before it ships. New tracks and lessons land as they're built and verified.
