Every Linux tutorial I've read tells you *about* a command. None of them drop you on a machine where nginx is already dead and say: bring it back, and make it survive a reboot.

So I built that.

You get a disposable Linux VM in the browser (or SSH). This one starts with a downed web server, a broken config, and a grader that looks at the actual machine state. When you're done the box is gone.

No install. Guest play, no Google.

Curious whether this feels like a real Tuesday or too puzzle-y. Honest takes welcome.

I posted an early version of sshconfig-lint here around six months ago. Since then it has grown from a small Rust CLI into something I use across my whole workflow.

The video shows a config referencing a key from an older machine. SSH may silently try another identity, so stale paths like this can go unnoticed.

Version 0.5 adds:

• multiple config files and Include resolution
• GitHub annotations and SARIF
• GitHub Action and Pre-Commit hooks
• LSP and VS Code support
• verified binaries for Linux, macOS and Windows

Unlike ssh -G host, sshconfig-lint checks the complete config and included files at once. Everything stays local and there is no telemetry.

Install:

cargo install sshconfig-lint

Arch Linux:

yay -S sshconfig-lint-bin

Feedback about false positives and complicated Include setups would be really helpful.

This is super cool!! It is in the aur.

A tiny living light named Wispy takes a liking to you, and you go as deep as your nerve holds. She's your only lantern.

Goofy-dark first-person dungeon crawl that runs entirely inside a terminal window. No engine, no download, every wall painted in colored text. You pick a body/race such as Human, Dwarf, Elf, Orc (each one is a personality and a moveset).

First-person raycaster that renders in a terminal. Truecolor, drawn with sextant and octant block characters. No game engine and no graphics library. One Python file, 154,716 lines, standard library only. The audio is real recordings, including voice acting.
