What changed
- Learn now has a Vibecode mode with Practical Vibecoding, a course on building software with AI coding tools. It has readings, quizzes, and hands-on labs, and the first module is free.
- Pick AlgoArena Builder, Claude Code, Codex, or Cursor, and the course narrows to that tool's path and tracks your progress on it. Language tracks now show as a grid of logos with your progress on each.
- Problem difficulty ratings are now finer grained, so problems that used to share one round number now show their own ratings. Duplicate copies of the same problem were removed from the library.
