No. The fullness or emptiness depends on whether the last action was pouring water into or out of the jug.

[–] whereisk@lemmy.world 5 points 1 day ago (1 children)

Exactly - or the next action. The question “is the glass half full or empty” is a false dichotomy, the answer is: it is impossible to know without further info.

[–] Wizard_Pope@lemmy.world 1 points 1 day ago (1 children)

How exactly does it depend on next action? Is it half full by that logic if next action would be to fill it up further?

[–] whereisk@lemmy.world 5 points 1 day ago (1 children)

Yes. If the next action is to add it’s half full, if to remove it’s half empty. If nothing then it depends on the previous actions.

[–] BowtiesAreCool@lemmy.world 4 points 1 day ago (1 children)

So the glass is in a quantum superposition until an entity decides to act on it

[–] whereisk@lemmy.world 2 points 17 hours ago

That’s funny. But the glass is not in a superposition, the answer to the question is. It’s a glass that contains water and is just sitting there observable by all probably sick of being subject to stupid questions that have no meaningful answer.

Don't understand the joke? Most autistic people I know and me included are not that into math to that degree. Maybe someone with ADHD and autism may hyper fixate on it, but still it's not really something they would do usually?

People thinking autism is like a superpower or something don't really understand the disability.

[–] Shou@lemmy.world 1 points 3 hours ago

I think it more about detail oriented thinking rather than the big picture.

[–] AdrianTheFrog@lemmy.world 1 points 17 hours ago* (last edited 15 hours ago)

I'm not autistic, just ADHD but I do honestly feel like double checking that figure here

edit: i'd estimate 62.1% full

and assuming that glass is perfectly radially symmetric (idk if that is the correct term or not) you would not ever need to do that much math

if you had the actual glass you could probably do a much more accurate measurement just with a graduated cylinder

[–] Zacryon@feddit.org 3 points 1 day ago

The meme builds on a cliché about autistic people.

[–] Sam_Bass@lemmy.world 1 points 1 day ago

Focus is a superpower for us

[–] Discover5164@lemm.ee 20 points 2 days ago

hey where is the high res image? i need to check the math

[–] mukt@lemmy.ml 43 points 2 days ago* (last edited 2 days ago)

Why do High Functioning / Savants get to represent all autistic people all the time ?

EDIT : 60.69% of the time.

[–] JCpac 14 points 2 days ago

The topology enthusiast says the jug is full of glass

[–] Zagorath@aussie.zone 42 points 2 days ago (1 children)

Anyone else bothered by the inconsistent conjugation here? Should be "optimism" and "pessimism" to go with "autism".

[–] Hellstormy@lemmy.dbzer0.com 18 points 2 days ago (1 children)

Yes. Or change "autism" to "autist".

[–] Zagorath@aussie.zone 7 points 2 days ago

Yeah you definitely could. Personally I wouldn't be bothered by it in a humorous context like this. But I know that's a term that does sometimes cause offence, so I chose the alternative.

[–] SpaceNoodle@lemmy.world 48 points 2 days ago (3 children)

I'd weigh the jug as-is, then weigh it full, and then weigh it empty; the proceeding trivial calculation of the original filled volume would be arguably more accurate.

[–] Dagnet@lemmy.world 37 points 2 days ago (2 children)

The engineering way to do it. Why go through the trouble of perfectly modeling it if you can just test a few times. Either that or consider the jug a cylinder and add a safety factor of 2.

[–] sga@lemmings.world 5 points 2 days ago

the safety factor got me

[–] SpaceNoodle@lemmy.world 8 points 2 days ago

It also gives you a way to validate your calculations when you inevitably do model it.

[–] SubArcticTundra@lemmy.ml 12 points 2 days ago* (last edited 2 days ago)

Behold, the pragmatist.

[–] AnnaFrankfurter@lemmy.ml 23 points 2 days ago (1 children)

Hey we need people like that, remember when an autistic person discovered few hundred millisecond delay in ssh which uncovered Jia Tan backdoor.

[–] ravermeister@lemmy.rimkus.it 2 points 18 hours ago (1 children)

Is there an article about that, I would like to read some more about this topic😊

[–] AnnaFrankfurter@lemmy.ml 2 points 14 hours ago* (last edited 14 hours ago) (1 children)

This is the original email by the person who discovered this backdoor. But if you want you can search for xz backdoor and you'll find a lot more articles which explain timelines and other things. https://www.openwall.com/lists/oss-security/2024/03/29/4

 == Observing Impact on openssh server ==

With the backdoored liblzma installed, logins via ssh become a lot slower.

time ssh nonexistant@...alhost

before:
nonexistant@...alhost: Permission denied (publickey).

before:
real	0m0.299s
user	0m0.202s
sys	0m0.006s

after:
nonexistant@...alhost: Permission denied (publickey).

real	0m0.807s
user	0m0.202s
sys	0m0.006s

That's a 500ms or 0.5s difference

[–] ravermeister@lemmy.rimkus.it 2 points 4 hours ago

Thanks 🙏👌✌️

A) The water isn't pure there will be minerals dissolved in it

B) There is likely water vapor in the air occupying the jug

[–] manicdave@feddit.uk 6 points 2 days ago (1 children)

What's really gonna bake your noodle is that the jug will be less full of you tilt it to the right slightly.

[–] asdfasdfasdf@lemmy.world 4 points 2 days ago (1 children)
[–] meyotch@slrpnk.net 4 points 2 days ago

Because the pouring spout is to the right. Tip it, you’ll see. It works better if you are staring closely at the spout from below when you do so.

[–] Etterra@discuss.online 13 points 2 days ago (1 children)

Literalist: The glass contains about 50% water.

Nihilist: The glass doesn't matter.

Anarchist: The glass is now full of piss.

Absurdist: the glass is now upside-down without spilling the water.

Me: I don't know who's glass this is so it's going in the sink.

Dadaist: ce n'est pas un verre.

[–] lime@feddit.nu 14 points 2 days ago (1 children)

i'm not too fond of the autistic superintelligence meme. yes there are people like this, but personally i can't math for shit.

i could probably go on about an interesting locomotive i found yesterday if you want a few hours wasted though...

[–] Tobberone@lemm.ee 6 points 2 days ago (1 children)

I didn't read super intelligence into it, I read overdoing and I found that it struck home. I don't know math either, but if I did, I would have done the same calculation.

[–] lime@feddit.nu 3 points 2 days ago

that's fair.

[–] lukewarm_ozone 10 points 2 days ago (1 children)

This roughly checks out. I'm getting 66%, based on the methodology of cutting out the jug's shape from the picture and numerically integrating the filled and empty volume (e.g. if a row is d pixels wide, it contributes d^2 to the volume, either filled or empty depending on whether it's above or below the water level).

[–] fu@libranet.de 1 points 2 days ago (1 children)
[–] lukewarm_ozone 2 points 1 day ago

The thing I said I did? Yes; here's the processed image:

If you mean the math in the post, I can't read it in this picture but it's probably just some boring body-of-rotation-related integrals, so basically the same thing as I did but breaking apart the vase's visible shape into analytically simple parts, whereas I got the shape from the image directly.

[–] capt_wolf@lemmy.world 12 points 2 days ago

Pfff... Didn't even calculate for the rate of evaporation of the water... Amateur...

[–] RedditWanderer@lemmy.world 8 points 2 days ago (1 children)

Engineers: the jug is twice as big as it needs to be

[–] DarkenLM@sh.itjust.works 1 points 1 hour ago

It has a safety factor of 2 dB.

[–] iii@mander.xyz 6 points 2 days ago

Unless there's air inside the water
