The most sane interpretation is that Elon Musk was payed to dilute or destroy Twitter. I can't think of anything else that would make sense. Throwing 44 billion dollars on a company and then gutting it for everything that was valuable including a unique brand that had even its own verb? But the sad reality is probably that a 12 years old narcissist edgelord in the body of a billionaire wanted a vanity plate.

This would explain things, if there was a credible suggestion for who's pulling the strings. The theory of Elop destroying Nokia (consumer) makes sense, because he was at Microsoft, went to Nokia sold it to Microsoft at diminished value and stayed there for a good amount of time. But who would pay Musk for this? And how will he be compensated? Afaik, he's lighting a bunch of his own money on fire. Although, there has…

I've seen theories about Saudis paying for this in order to prevent the next Arab Spring, in which Twitter played a key role for the protesters to organize themselves. Seems a bit far-fetched, but these days, who knows?

I'm responsible for this character being supported in Iosevka, JetBrains Mono, 3270, and Cozette, looks like. For arguments I wanted to stick to mathematical convention like f(x) without looking like a regular variable. While the lowercase 𝕩 (subject role) is more common, uppercase makes it a function and is useful in functional programming. More visibility for the character is helpful if it means wider font support…

I wasn't familiar with BQN. Clicked through, reminded me of APL. "OH", I thought, "I see how you came up with the name." There was a (disproven) urban legend about Arthur C. Clarke's 2001, where "HAL" was secretly a reference to "IBM", where you transpose each letter by one.

H + 1 = I

A + 1 = B

L + 1 = M

Man, BQN is a clever name. Because,

A + 1 = B

P + 1 = Q

L + 1 = M...

...well crap. That theory didn't pan out at all. Needlessly disappointed myself upon hearing that it's short for "Big Questions Notation".

Funny. Coming from a non-math background, having only one symbol to deal with feels less confusing than switching around symbols based on the medium it happens to be written on. Did one of the symbols come "first"?

Here you have the whole history: https://en.wikipedia.org/wiki/Blackboard_bold Summary: boldface came first, in print, and was widely used. Much later, some mathematicians started to write blackboard bold on blackboards (because actual bold would be very untoward to write on a blackboard). Then, the usage was backported to print. I find it ugly, a sort of breaking "suspension of disbelief", I don't know how to explai…

That's pretty typical for how typography develops. Majuscule and miniscule letters were just two different styles of writing the same letter. But eventually, people started using majuscule (i.e uppercase) letters to give emphasis to the beginning of sentences or certain words, like names.

Italic typefaces were created by Italian type designers to mimic the cursive handwriting of the time. They weren't meant to be mixed with roman style typefaces. However, typesetters who had access to both roman and italic fonts started to use italic for emphasis when typesetting texts in roman type.

And of course blackletter is also just a style that originally tried to mimic earlier handwriting.

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.

Interesting comment on the Register (by Jedit): However, it's also exactly identical to Unicode character 1D54F - because that's all it is. And if you examine the full "X" logo in detail, you'll notice that the scratch in the background doesn't reach the X because all the logo creator did was put U+1D54F in a black square and slap it onto the backdrop. It's the epitome of laziness. https://forums.theregister.com/foru…

Fun fact: this has happened before! > Apple's adaptation of the [⌘] symbol — encoded in Unicode at U+2318 — was derived in part from its use in Nordic countries as an indicator of cultural locations and places of interest. > ... > She was browsing through a symbol dictionary when she came across the cloverleaf-like symbol https://en.wikipedia.org/wiki/Command_key

That’s not really the same thing?

It’s not like Apple’s corporate logo was scanned from a Swedish symbol dictionary by some random person who passed it off as their work. Which is effectively what happened to X-Twitter.

Now that I think about it, most double stroked characters really represent "concrete" objects, not generic ones. Like ℙ for projective space, or 𝔸 for affine space. Also 𝔽 is often used together with an index 𝔽_q for the field with q elements. On the other hand, Wikipedia[1] agrees with you, that 𝕏 is "occasionally" used for metric spaces. [1] https://en.wikipedia.org/wiki/Blackboard_bold

I've seen ℙ used for probability.

I’ve also seen ⅆ as the differential operator and 𝔼(X) as the expected value of X. I think I’ve also seen 𝟙_x, and ⅈ, and ⅉ but I don’t remember for what.

I understand equations, both the simple and quadratical!

Seems like you've got a solid math grounding. If you're looking to expand on your history knowledge, I'd recommend taking a look at Creasy: https://en.wikipedia.org/wiki/The_Fifteen_Decisive_Battles_o...

They were spoofing Modern Major General.

So was I :-)
