A good bandwidth saver then, even for the 'share this' kind of plugins that exist.

Earlier quoted context omitted.

𝕏 is used as a symbol for a generic metric space. E.g. if your result is generic over ℝ², ℂ³, etc, you can write 𝕏.

I'm a PhD student in algebraic geometry and have seldom seen this. IME "X" is a generic name for all kinds of spaces (metric, topological, complex analytic, algebraic...), but I don't remember ever having seen "𝕏". That said, in principal everyone is free to call their spaces how they like. It just makes it easier to read if one sticks to familiar notation.

You're right I should've used "as a symbol" not "as the symbol". It's not terribly common.

I thought it was U+130B8.

Getting a proposal for a sufficiently flaccid variant approved by the Unicode Technical Committee was too big a lift.

But X windows is dead or dying. Oh, so is Twitter?

Reports of X11's death have been greatly exaggerated as far as I can see; it's still clinging stubbornly on, and efforts to kill it have tended not to go well.

Wayland is still trying really hard.

Musk can seem to do no right atm, I see a lot of hate out there with this name change and planned product expansion but I can’t quite understand why. He’s taking an underperforming social network and trying to make it work. It might prove fatal, but it would have died a slow boring death in its old form. Perhaps its just that people don’t like his personality, which shouldn’t come into it. Fwiw even prior to his defu…

You answered your own questions really with "Musk can seem to do no right atm" - for some of us, it's just incredibly funny to watch the hubris of a self-proclaimed genius cause them to fail so often in such a short space of time. A seemingly endless string of stupid decisions because he's surrounded by boot lickers and sycophants with not one of them willing to put their hand up and tell him he's not a genius.

Isn't a trademark always tied to its respective business domain?

Yes, but those "classes" can be quite wide, there is for example no way they could trademark it for "Class 9: Computer and software products and electrical and scientific products."

Wait until you find out about "apple" and "windows".

Can someone explain what we are talking about here? Something having to do with Musk's son's name?

No it's about the renaming of Twitter. [0] https://nitter.net/elonmusk

So it’s about Musk’s son name
