Welcome to Known Issues.

This shop is for people who’ve been around computers long enough to know that some problems aren’t bugs — they’re traditions. From command lines and man pages to late nights, bad ideas, and worse outcomes, our designs are quiet nods to open-source culture and the people who keep it running.

If you know, you know.
If you don’t, maybe don’t run it.

Coffee mugs, shirts, and small pieces of humor for developers, sysadmins, and anyone who’s learned the hard way. No tutorials, no explanations — just familiar phrases that have survived longer than most software.

Proceed with caution.
