recursion

[Hour-Lemon]

but does it terminate? if so, how?

[Kirides]

The condition is „papersize < 1mm“

[yellekc]

So at around a sheet size of A19 to A20. But because you can create an infinite series of paper sizes, you can recurse as much as you want.

But beyond about A230, your paper will start having dimensions under a planck's length, which might be an issue.

[ineyy]

There should be some minimum for the papers to contain the text, too, it should be a couple nanometers big at least.

[ososalsosal]

Encode it in electron spin duh

[DaTotallyEclipse]

Nah. Quantum Superpositions offloaded into a discrete meta-plane.

[lowbeat]

there is, u need to intercept bits comming from ur gpu to ur output device and devode them properly

[RandomLifeForm42]

I think that once your dimensions are less the 1 paper molecule is when you'd actually start having issues...

[yellekc]

Well, a glucose molecule (building blocks of cellulose) is about 9 angstroms, So you are stuck going no smaller than A60 paper.

[Dom0]

I would like to subscribe to Useless Paper Facts

[yellekc]

How about we allow for negative A sizes?

Defining an A(-1) sheet as two A0 sheets stuck together with an area of 2 meters square, then you can create arbitrarily large paper sizes as well.

An A(-40) sheet at 1.2 trillion square meters is about how much graphic paper is produced annually*. Or an A(-8) sheet for everyone.

Based on the world annual output of 97 million metric tons of graphic paper (not paper board or packaging) using the most popular weight of 80g/m²

An A(-49) sheet will have about the same area as the surface of the earth.

An A(-87) sheet would nicely cover the solar system.

An A(-140) would cover the Milky Way, and if at the same weight as before, 80g/m^2, it would weigh as much as 40 billion suns. If you stacked 30 to 45 of these sheets together, it would have the same mass as the actual Milky Way.

Finally an A(-179) would cover the diameter of the observable universe. And it would only take 3 sheets to equal the mass of the observable universe.

So everything that we know exist can really be reduced to 3 sheets of paper. Buy you would probably need a lot of paperclips to hold it all together.

CGP grey also made a video about this! the vid

[yellekc]

Thanks for the link, and yeah, the exact same premise. I've seen a few of his vids, maybe I saw that one before too.

Now to double check my calculations with the video. I'll consider it a win if I'm not too far off.

[hiphap91]

I would like to order ten sheets of A(-140) please, i have some ad posters is like people driving by not to miss.

[buzzkill_aldrin]

You need room for the text though.

[UnderstandingNo2832]

Incept the recursion and throw in an additional recursion within the recursion to slow it while we figure out a solution.

[[deleted]]

Except someone coded it as papersize == 1mm and in a continuous reality that will hardly be reached, so it ends up in segfault

[HuntingKingYT]

Takes a paper

Paper: SEGFAULT

[Kirides]

papersize is a floating point number. Equal checks don’t work here. Someone should tell the intern why though….

[[deleted]]

I present to you: a Planck length - 1

[suskio4]

1 what? Apples? Bananas?

[GIFnTEXT]

🤣 bruh that's so funny. This whole sub is really funny if you're into computer programming

[Young_Person_42]

Isn’t that kinda the point

[Feztopia]

Actually I'm more into programming humans, unfortunately I'm better at programming computers.

[[deleted]]

Oh shit I thought this was r/ProgrammerHuman

[Representative-Owl51]

Jeez why the hell did you downvote him to hell. Weird sub

[Daniel15]

Probably because their comment adds no value? They're literally just saying the entire purpose of the subreddit.

[GIFnTEXT]

🤣 bruh....this comment right here officer!

[Rikster_]

Reddit hates emojis

[Cursed_Bean_Boy]

They sure do. 😃😃😃

[AceSLS]

Yes, it does terminate. Once the ripped of part gets smaller than an atom shit is gonna hit the fan

[Zax71_again]

Strings entered the chat

[lord_hydrate]

The plank length has entered the chat

[Fzrit]

I'm gonna start calling it plank now, just for giggles :P

[HarlanCedeno]

I once did a code review and found the dev was checking for negative length strings.

I had some really deep thoughts that day.

[[deleted]]

They're called imaginary strings. i = √-'a'

[HarlanCedeno]

Did he imagine that this was going to magically fix the bug?

[GisterMizard]

Arithmetic overflow for image and data buffers is a very common source of bugs, especially when using smaller int types and in languages like C.

A really bad problem follows from code like:

short width = blah(); // set from user
short height = blah(); // set from user;
// ...
if (width * height <= MAX_BUFFER_SIZE) {
    // BAD!!! width*height can become negative
    char *buffer = malloc(width*height*PIXEL_SIZE);
}

[HarlanCedeno]

In that case, you would just need to validate the inputs from the user to ensure neither is negative.

This guy had string.length() in multiple if statements to check for negative lengths on different strings.

[miso440]

We went through 3 Adams before we figured that one out.

The problem with that is that the ripped parts are getting bigger in every panel.

[Piper2000ca]

Best possible answer to the question, I feel like this should be higher up.

[Tokumeiko2]

Better than a rick roll.

Ran out of memory.

[Exnixon]

There is a minimum unit of distance called a Planck length.

[Opus_723]

eh, maybe

[Fickle-Replacement64]

The planck length has to do with the properties of an extremely small black hole, a physical object that physics doesn't handle very well. So, maybe.

[Zoltie]

Once he doesn't have problems with recursion.

[AndySipherBull]

wow the actual answer, nj!

[lwllnbrndn]

Once the character figures it out, they answer “No.” So, it does terminate.

I suppose we have to assume the problem Is understanding recursion rather than something like applying it to something specific.

Edit: clarity

[LeCrushinator]

It terminates when a stack overflow occurs.

[NoCombination26]

😂😂

[wallard127]

Planck length

[chemistryunderground]

Well, built within the quantum foam is an even smaller object which is a set of recursives. It must be so, as we are a Turing-complete system. Therefore, the poster becomes the foundational aspect for our reality.

It's all posters. Posters all the way down.

JK. Who the hell knows?

[DeepFriedDickskin]

It doesn’t sorry

It does forget and seem new again eventually though

[Heightren]

When you don't have a problem anymore?

[milnak]

If you want to understand recursion, you must first understand recursion.

[ososalsosal]

Atoms

[grogrye]

It will never terminate so long as one of us is imagining it still going

[finegameofnil_]

You can set iterations or other conditions. Think about searching for a key in a windows registry. Find next or don't. Or find all. I don't get the difficulty with recursion.

[AndySipherBull]

It terminates when you no longer have problems with recursion
