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.

@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.

@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)...

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.

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 ...

A friend of mine is a Doctor. On the train this morning on their way to work the call comes out. "Do we have any doctors on board?".

Finally. Friend grabs their bag and makes way through the train. Only to find 14 other doctors had done the same thing...

Guess that route is popular with medical staff on their way to work...

As the Sun slips towards the western horizon as seen from The Netherlands, it's fascinating to think that the Moon is also in this picture.

And that as seen from some points on Earth, the Moon is already partly covering the Sun, the path of totality sweeping across the Pacific towards the Mexican mainland to arrive in half an hour or so.

But our view here? Nada 🤷‍♂️

The following will probably only make sense to people in the UK.

I have a vague sense that the job of "lollipop person" used to be fairly strongly gendered, but I can't remember which way - is it lollipop man, or lollipop lady? I feel like "lollipop lady" sounds more like what I said growing up, but both lollipop people at my kids' school are men and I've overthought it and now I'm suffering from semantic satiation.

So, was it a lollipop man or a lollipop lady when you were at school?

The "cutest" thing about the number 2024 that I can come up with is that it can be generated from the digits 1,,..,5 like this:

2024=3⁴×5²−1

Anybody got any other "cute" things to do with that new year?

Until today I did not know that there is a mastodon client for Android that supports mathJax (i.e. latex rendering). I had been resigned to reading math on the desktop and using the app basically for skimming clear text only.
If you are like me, then go to the Android play store and download "mathstodon" (yes, really). Looks and feels like the generic tusky except that suddenly you can read equations!
(Now I just need to find the time to spend online...)

If the great power of LLMs is to look at a sequence of tokens and sus out which one plausibly comes next, has anybody tried to train one of these on the first trillion (or however many we have these days) digits of π and let it try to give us the next thousand or so?
And then check how many it got right?
We'd all expect it to get 10% (in decimal) but imagine if it got 20% or 30%...

the autistic urge to use parentheses in every sentence (because you're afraid people will misunderstand it (or interpret additional meaning into it (which has happened before (many times (with terrible consequences (and i'm not even talking about the trauma this caused))))))

SvenGeier, (edited )
@SvenGeier@mathstodon.xyz avatar

@lis
I find I can avoid¹ most² parentheses by using footnotes⁷ 🤷‍♂️
¹) Or better "replace".
²) maybe even all? I can't really think of a counter example, but might well be missing something somewhere.
³) or at least the ones I talked to about this. There may well be a sampling bias here.
⁴) "irritating" may not be the best word here - there's a perception of pretentiousness about footnotes⁶ that parentheses don't seem to convey.
⁵) This footnote isn't even referenced anywhere. You found it anyways. Yay, you!
⁶) Probably owing to the difficulty of inserting and tracking them before computers took most of that burden from us.
⁷) many people³ appear to find footnotes irritating⁴, but they don't break up the reading flow as much as parentheses do.

Some password advice from an infosec professional:

Good password hygiene means choosing a password that is hard to guess.

One that's hard to type. Hard to remember. Hard to think about. Hard to LOOK at.

A password that makes you feel disoriented, uncomfortable.

In short, your password should be a Cthulhu.
