Are you using the standard xattr command that’s built into macOS? IIRC there’s another program out there by the same name with completely different syntax. Try running type xattr; it should say something like “xattr is /usr/bin/xattr” if you’re using the standard one.
I am going to blame Microsoft, because “works out of the box” shouldn’t conflict with “secure out of the box.”
And while I won’t blame Linus for insecure-by-default Linux configs, I will blame whoever integrated the distro/dockerfile/etc.
I remember when the local Safeway had one of these! I’m pretty sure that was in the '70s, though. It’s just slightly possible that I might be old.
I’ve also been watching CtC quite a bit for the last couple of years. Unfortunately, they’ve lately been doing a lot of long, highly technical puzzles, which I don’t find as interesting (though their shorter videos are still good). If anyone’s interested in checking them out, I’ll recommend a couple of older videos that I really enjoyed:
If you enjoy watching people solve sudokus and other puzzles, I’ll also recommend Rangsk (generally does the daily NYT hard sudoku, a 6x6 intro-to-nonstandard-rules “sudoku adventure”, and a collection of wordle-ish (but not not actually wordle) games), Bremster, and zetamath (does quite a few live solves with audience participation, as well as reaction vids to other people solving his puzzles).
Nobody has ported Doom to a Himalayan salt lamp.
Yet.
This is your opportunity!
