Hi, I’m 404human.

Building Rust runtimes, reliable background jobs, and AI infrastructure. Sharing the experiments, failures, and releases.

Now

• running

  Building Service Monitor, a Rust uptime monitor, one tested checkpoint at a time.

• running

  Building a Rust knowledge base with Claude Code, checked by exams the AI can’t see.

• running

  Writing up each experiment here, including the parts that didn’t work.

Projects

• 2026
  Service Monitor in progress

  Keeps an eye on your websites and tells you, honestly, when something breaks. Written in Rust, built in the open, one tested step at a time.

• 2026
  Teaching an AI Rust write-up

  Claude studied the entire Rust Book, then took hidden-test exams with no compiler. 59/59 on a final test full of decoys.

  This site live

  A text-only portfolio and blog built with Zola. No theme, no tracking.

Writing

• 2026-10-14 experiment
  I made an AI read the entire Rust Book. Then I tried to make it fail.

  It passed. But the most interesting part was the one bug it did write.
