we need metacomputers.

one of the big features of computers and how they improved productivity was how they let us automate a lot of things that we had to do by hand before.

well, most of the things I have to do by hand these days involve badly designed software.

@foone The VNC protocol basically lets you do just that...

Using the Schröder–Bernstein theorem to prove that the closed interval [0,1] has the same cardinality as the open interval (0,1) is like using a nuclear reactor to boil an egg.

@ProfKinyon I'm unclear about the "X otherwise" branch: don't the other two cases already cover the full A⋃B range?

Ah, yes, in the uncountable case this makes sense. I hadn't really thought that far...

SvenGeier,

@johncarlosbaez It feels like in the countable case I should be able to re-order things into a bijection with ℕ first with (a_{n\in{ℕ}}) . I'm not a barbarian...

Some years ago, I read @cstross 's "The Jennifer Morgue" (good book, second in "The Laundry Files" series), in which a Smart Car with an "EJECT" button was a plot point.

I was idly wandering through Ebay while waiting for the dealership to invoice me for my new-to-me second-hand Smart Car last month. When I encountered someone selling an anodised aluminium "Eject" button that plugs into the cigarette lighter socket, I felt the heavy weight of inevitability settle across my shoulders :D

Closeup of the centre console of the car, showing a red button with an open flip-cover, the word EJECT written on it in white capital letters.

The only cyborg I've seen get it right is Inspector Gadget.

Because I can probably name ten people right now who would go for the "motorized screwdriver in the finger" surgery, yet it so rarely shows up in fiction.

But that's the transhumanist future I'm waiting for

Given a random number generator that generates points uniformly in the unit interval [0,1] can you generate uniformly distributed points in the unit circle using only algebraic functions? In a finite number of steps - so no rejection sampling, loops, recursion. No "almost always" finite either.

Just wondering about sitiations where it seems you can't avoid trig functions.

SvenGeier,
@SvenGeier@mathstodon.xyz avatar

@BoydStephenSmithJr @dpiponi This has the same number of points on each circle around the origin, meaning the density goes to ∞ at zero.- definitely not uniform.

SvenGeier,
@SvenGeier@mathstodon.xyz avatar

@dpiponi @BoydStephenSmithJr Yeah - I am definitely trouble coming up with the right words when it comes to ... "density"(?) of things. One of these millenia I'll write up where I think there's some missing nomenclature (and or ask whether maybe it exists and I'm just unaware of it)...

It's definitely true that there are 35 atoms in the universe, though. Maybe even more. But certainly at least those 35.

Microsoft Teams continues to reveal its true nature as a billion sprint goals in a trenchcoat:

When you attach an image to a post, it's saved at the top of the Sharepoint folder belonging to the channel. (So the "files" tab becomes a cluttered mess, but that's not what I'm cross about now)

As well as restrictions on valid filenames, filenames of attachments have to be unique.

So if you've attached drawing.png once before, and upload another drawing.png, Teams asks if you want to replace the original, or keep both. If you keep both, it adds (1) to the filename.

... unless there's already a "drawing (1).png", in which case it asks you AGAIN what you want to do.

Is there a Big Brain Cloud Services reason it can't automatically find the smallest number that works?

Of course what it should do is drawing (1,(1)).png ...

ChatGPT gives you the most plausible or most likely answer you could expect if you asked the same question somewhere on the internet (or, more precisely, that parts of the internet that was used for training). It is quite literally a mirror, that shows you what humans say and do.
When you see ugliness in a mirror, it does not behoove a self-aware being to try to blame the mirror.
