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. [tmpfs.tech](https://tmpfs.tech) Curious whether this feels like a real Tuesday or too puzzle-y. Honest takes welcome.   submitted by   /u/binrick [link]   [comments]
