- Don't get baited into back-and-forth insults. We are not animals.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry will not be tolerated.
3. Post Linux-related content

What that garble of symbols does, is that it defines and calls a function named
:, which calls itself twice.The syntax for defining a function is different in Fish, so no, this particular garble will not work:
But it is, of course, possible to write a (much more readable) version that will work in Fish.
you can write a more readable version in any shell, it's intentionally unreadable
Yeah, I meant, as an attacker, you couldn't come up with a similarly unreadable version.
At least, as far as I can tell, defining a function requires spelling out
functionand seems to require being defined on multiple lines, too.Oh, I see. That's very nice then
Unfortunately it works in zsh. I just had to kill my laptop after curiosity got the better of me.

The ampersand looks very weird in that font. It would bug me.
It hails back to the early days of the ampersand, from when it was basically still just Latin "et": https://commons.wikimedia.org/wiki/File:Trebuchet_MS_ampersand.svg
Personally, I do like this font (Fira Mono+Sans), because it still looks professional, without being so boring that I get depression from looking at it.
But yeah, that ampersand is pushing it a bit, as I'm not sure everyone else knows that's an ampersand...
