AI Analysis

●●SolidCozyWizardry

Fits a multi-arch Matrix rain demo in 2KB, beating the official hello-world on size.

Strengths
  • •Hand-written x86_64 and ARM64 assembly keeps the binary tiny.
  • •Multi-arch support via buildx without bloating the single-arch tags.
  • •Proper signal handling ensures Ctrl-C cleans up the terminal.
Weaknesses
  • •Purely novelty; no practical utility beyond the initial 'cool' factor.
  • •Limited audience compared to actual debugging or monitoring tools.
Target Audience

DevOps engineers, Docker users, assembly hobbyists

Post Description

I often run `docker run hello-world` after setup as a basic check. But I feel a bit boring.

So here's what I do instead:

docker run --rm -it warachet/hello-world

You get Matrix digital rain. Ctrl-C cleans up properly.

hello-world (official) ~9-13 kB warachet/hello-world ~4.4 kB multi-arch, ~2 kB single-arch

Not a serious work, just a fun thing to hack on and share.
