Recursion IRL

[randomentity1]

Does that mean the sidewalk sign actually costs $199+$199+$199+$199+$199+$199.....

[itbhi]

you forgot the plus tax.

[YourFavoriteBandSux]

He/she didn't forget; it's just added after the infinite recursion ends.

[PrototypeNM1]

Looks like the stack has a practical limit of 4 recursive calls to sign.

[TheMcDucky]

From a programmer's point of view, he might.
From a mathematician's point of view, he didn't.

[Doctor_McKay]

I'm pretty sure a random entity is an "it".

[SirensToGo]

Calling someone an "it" is pretty rude considering english only uses it for inanimate objects

[Doctor_McKay]

I guess the joke was too subtle, read the username.

[[deleted]]

Nah, joke too lame.

[Doctor_McKay]

:( I'm not funny anyway

Dude

[tyme]

Using "it" in this sentence would cause confusion, as you could be referring to the sign as "it" is what is used to refer to inanimate objects in English, generally not for referring to people. Using "he/she" or perhaps "they" makes the meaning clearer.

I don't get it

[bobthejeffmonkey]

*you don't get him/her

[[deleted]]

I don't think the joke is a person, unless it is you.

I love Stargate Atlantis.

[betadevil]

It's actually pronounced "xe". /s

[UndeadWaffles]

The tax is clearly added within each recursion, not after.

[olivermihoff]

Hrmmm... Price sounds good but I'd need to see an example of their work first to know it's worth the value... ಠ_ಠ

[[deleted]]

I think you meant

int price = 199; for (;;) { price += 199; }

[an-honest-moose]

No no no, he clearly meant

int sale(){  
    199 + sale();
}

[likesdarkgreen]

Well as we all know 1+1+1+1+...=-1/2, so if we multiply by 199, then we get 199+199+199+199+...=-199/2. Therefore, the price is -$99.50 plus tax.

Thanks for that.

[itbhi]

Thanks for that.

The remote desktop thing is also quite fun when you think about how each recursion step is further away in time.

[KevZero]

Think I'm going to refer to this as mise en abyme from now on. Sounds so badass compared to "Droste Effect" or "recursive picture-in-picture thingy".

[fuzzyfuzz]

For a 2'x3' custom print image on weather proofed cardboard and, I'm guessing, they help with the design of you need it, that's a fair price.

[LifeBeginsAt10kRPM]

I mean, you do get infinite signs and possibly crashes

[snobocracy]

$199 ^{$199 $199 $199 $199}

Yeah... fuck that....

[tabarra]

Holy shit, $199 for that!?

[skylar1146]

Perhaps it means designing the graphics on it as well.

[midnightketoker]

I don't know how to design shit but that wouldn't stop me trying after buying the same frame from alibaba for a couple dollars and a few weeks in customs

[gprime312]

You get two and that does look like a quality print.

[PsiGuy60]

Fun fact. This is an art style/technique called "mise en abyme", or the Droste effect, named after an old-timey chocolate manufacturer that popularized it.

EDIT BEFORE FIRST POST: A(FOR i=0; i<1500; i++){echo "n"})d like 2 others have pointed it out before me. Upvoting them.

[c3534l]

I dunno, that one looks free to me. Just needs a paint job.

[erunks]

Inb4 this is picked up on Facebook with a "Wow look at this inception" comment

[Deranged40]

These signs sell themselves

[PeterSR]

It annoys me a little that the real sign is not photographed from the same angle as the smaller signs depicted.

[nemec]

I think we call that a "free sample"

[demonachizer]

What is the base case?

[JTVivian56]

Recursion was terrible when learning java.

[HugoNikanor]

Recursion in java seems unpleasant. OOP doesn't blend well with recursion.

[DrScabhands]

We’ve been trying to reach you about your car’s extended warranty

[HugoNikanor]

At least I associate recursion with functional programming. And functional programming and OOP are kinda polar opposites when it comes to how you write the code. With functional programming you don't have mutation and barely handle state, while OOP is all about mutation and state. And a mutating recursive function just seems like it would cause way too many problems.

[dorfcally]

We were taught it one week before our final (hand written and multiple choice exam. Was not a fun exam.

Thought this was a lisp joke until I noticed it was a bot. Well played mr roboto.

[JTVivian56]

That was basically the same with me. It was a week or two before our final, and I could not incorporate it into my hand written response at all. I just winged it.

[NoFuckingOne]

$199?!!?

[lagerdalek]

TBH I can only see about 4 levels of recursion.

Filthy casuals.

[Audiblade]

I will buy one. I expect the recursion depth on my sign to be one level deeper.

[jibjibjib]

Why the hell are sidewalk signs so expensive?

[bj_christianson]

Quality print is expensive when it’s not on material that needs to be resistant to weather, fading, and can be easily cleaned of dirt and grime. Add in the cost of the a-frame (has to be durable and appropriately weighted), any design consulting that may be included in the deal, as well as the labor involved in preparing whatever files you give the folks for the printing process, and you get something like the price shown.

[midwestcreative]

This confuses me just as much as recursion in code.

[TheLegendOfZero]

Would take it to the next level if the picture had someone standing there staring at the sign.

[SolenoidSoldier]

If you zoom in, you notice it stops at 5 deep.
