A browser-based Rust course built around repairing deliberately broken exercises and checking the result with a real compiler.

Why it surfaced

Code Crab turns 94 rustlings exercises into a constrained learning path: one broken file, one compiler diagnostic, and one next step at a time. There is nothing to install, hints appear incrementally, and the copy makes a persuasive case for practice over passive video lessons.

Ham Is Specifically Discouraged

August 10’s newborn domains include a mock cryptid council that specifically discourages ham, a vintage phone collecting messages for Twyla’s 70th, a 4.5-meter dish measuring Galactic hydrogen at 1420 MHz, and an open index that found 530 sites permitting GPTBot in robots.txt while refusing it at the server.

This is one of 1,000 discoveries in the 2026-08-10 Domain Arrivals issue.
