Watt — The Lean Desktop Project

A meta-landing page for the two sister desktop suites by Geir Isene:

• CHasm — x86_64 assembly: shell, terminal, tiling WM, status bar, file viewer, font rasterizer, screen locker. The bedrock.
• Fe₂O₃ — Rust on a shared TUI library (crust): editor, file manager, web browser, messaging hub, calendar, astronomy, movies, music, color picker, battery triage. The application layer.

Together they form a complete Linux desktop that idles at ~3.6 W on a Dell XPS 14 — roughly 19 hours on a 70 Wh battery, screen on.

Why "Watt"?

Because a watt is the unit being optimised. Every loop, every timer, every fork-on-a-timer is measured in watts the battery doesn't give back. Watt is the umbrella under which both suites enforce the same three rules, in priority order:

1. No wasted CPU cycles. Gate every feature so its code path is fully cold when not in use.
2. Lightning fast. Microsecond startup, instantaneous user feedback. No interpreters in the hot path.
3. More battery life. Polling, waking, and forking on a timer are suspect. Prefer filesystem watches, select, blocking reads.
