Earlier quoted context omitted.

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…

It’s a useful convention; I’m not sure why you dislike it other than some invalid conception of purity.

Maybe because my favorite math books do not use this convention, but another equally valid and useful convention: regular boldface.

because elon renamed twitter to "x corp", bought the x.com domain and shoved this character on it.

The bird is a lot more recognizable, no? Maybe even beautiful?

Not only the bird, but all of the associated verbiage. For example, Tweet and Retweet. Do those go away after changing the name and logo?

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…

> you'll notice that the scratch in the background doesn't reach the X What does this mean? I've tried finding various images of the X logo on news sites and twitter.com itself and I don't see anything resembling a "scratch in the background" but maybe I'm just missing something obvious.

I believe they mean the marbling: The background surrounding the X is pure black, while the rest of the box is black with a bit of white marbling.

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.

Which is a natural state when the one in charge is insecure about their own actual weaknesses.

They’ll attack anyone who tells them the actual truth, and end up surrounded by those who either can’t see the truth (due to incompetence or delusion), or are willing to actively lie about it (manipulators). By process of elimination, if not by active choice.

This is for math. In Latex, you get these symbols with \mathbb{}. They are most commonly used to represent to represent number sets, like the set of all integers Z (from the German), set of all natural numbers N, set of complex numbers C, set of all real numbers R, rationals Q (for “quotient”), set of quaternions H (named after Hamilton), or an unknown set F (for “field”). This explains why many of the letters in thi…

> This is for math. Heh. The "tabs vs spaces" debate of mathematical typography is whether these symbols should be used at all in printing, or reserved for actual blackboards. In LaTeX you can have actual boldface letters, so you should write a boldface letter R to represent the real numbers and so on. Using "blackboard bold" in print looks terribly off to some (many?) people.

Why use the wrong symbol, when you can just use the correct (ie, blackboard bold) symbol?

For me it's not funny so much as shocking, and sad. He had a hand, of some sort, in at least a few great things, and it's upsetting to watch it falling apart. I often think of the quote: "You either die a hero, or live to see yourself become a villain." Far too many icons outlive their hero phase, and it's kind of depressing. Edit: Or rather, the hero phase fails to live long enough to outlive the person.

He certainly had his wallet involved with some interesting things but I think it's a stretch to say he had any beneficial hands-on involvement.

He’s produced a lot of value for a lot of people over the years, and many things some of us see every day (like Teslas) are only the way they are/have been successful the way they are because of his influence.

It’s always been more as a promoter and image seller, but he has also been willing to make big calls and take risks others won’t which has allowed them to grow. That is valuable. And he has been hands on in some areas sometimes in ways that have been instrumental in shaping things. For better or worse.

He’s far from perfect. But no one is, and honesty is important.

I suspect the big issue here is something typical of narcissists - he’s gotten older, and he can’t keep up his game convincingly enough anymore to fool a large enough percentage of the public, so he’s downward spiraling. And internally he can feel it, which makes it worse.

It would explain a lot, especially the often bizarre and destructive attacks on anyone who says anything he doesn’t like. The over the top edgy/controversial behavior to get reactions, etc.

Yeah lol, Musk wants to call them xs now. Like "your x last night was pretty great" or "will you share your x with me again?"

Not even kidding. https://apnews.com/article/twitter-x-logo-blue-bird-musk-068...

> In response to questions about what tweets would be called when the rebranding is done, Musk said they would be called Xs.

I hated when textbooks/papers did this. Half the time you can't tell if they meant to use the bold letter or if the printer was just being generous on that character. Made legibility quite a bit more difficult. BB letters are unambiguous.

I thought the same thing. The bird is endearing. Changing it to X is something some edgy teenager would do. I can't help but wonder if he's trying to destroy twitter on purpose.

This whole Twitter saga is like what happens when a cat catches a bird and doesn't know what to do with it so just slowly tortures it to death for the hell of it

The point isn’t to be “right” — whatever you define that as.

The point is to be understood.

Use blackboard bold when it’s what people are most familiar with and will engender the least confusion.

You call this the “tabs vs spaces” debate, but I’ve literally never heard anyone advocate your position until you did, just now.
