Does this have anything to do with the cage fight/dick measuring content with Zuckerberg? I think almost everybody thought renaming Facebook to Meta was a bad idea, but maybe Musk knows something we don’t. ;-)

> I think almost everybody thought renaming Facebook to Meta was a bad idea Do they? Why? I don't see how it did any harm, and people are way more willing to admit an association with Meta than with Facebook.

When it first happened I thought they were trying to evade Facebook’s bad reputation for privacy and politics and made a point to keep calling it Facebook.

After about a year “Meta” had the same stink of death around it as NFTs and I figured I’d be doing it no favor by calling it by its preferred name.

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…

That's what happens when you fire everyone but programmers. I'm surprised it isn't AI generated (isn't Musk starting an AI company? So maybe it actually is)

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

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

As a counterpoint, 𝔽 when not fixed to a particular size is arguably still generic over "any field", and 𝔾 is most definitely generic for "any group", even if fixed to a particular size.

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.

> In LaTeX you can have actual boldface letters, so you should write a boldface letter R to represent the real numbers and so on.

Almost [1] every single student absolutely hates that notation in scripts. Bold is used to draw attention, it should not be abused as being part of the variable/type. Just use the proper symbol.

[1] And I'm only saying "almost" to account for the possibility of there being like 5 super weird people on this planet that think otherwise. I don't know a single person who thinks this is a good idea, even the professors writing their scripts like that think it's stupid and are only doing it due to some nonsense fear of it otherwise not printing correctly due to one single bad experience with a shitty printer in 1950. Or maybe there's some other historical reason for this, but in 2023 I'd classify not using the better notation as malicious.

Twitter was doing fine. By taking it private, he saddled it with massive debt its current revenue couldn’t service. And every decision thereafter has been half baked and poorly executed. So by trying to “save” it, he’s killing it much quicker than if it had just been left alone.

That is not at all what looking at their financials say. Twitter was a very profitable company which over hired like crazy in 2021. This could have been solved without gong crazy like Musk did. Just do responsible layoffs.

There are no articles to confirm that it was losing $4m a day prior to the acquisition. This is a number that Elon put out (post acquisition) to justify layoffs.

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…

> Few would argue that it works better now than before

Maybe in the social circles you stick to, but there are plenty of /other/ people (i.e. more than a "few") that are quite happy that the 80% of employees doing their jobs were let go. [1]

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.

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.

The reality is that the hero likely never existed.
