Code Golfer's Corner

Discussion specific to golfing code. For general PPCG chatter ...

@xnor ^

Reto Koradi

Well, if you want something that's on topic, I got a CJam question for @Dennis, or anybody else who has insight: Why can't I do a find for a string in an array of strings? For example: ["A" "B" "C"] "B" #

xnor

@AlexA. thanks

would it be hard to have questions on main posted there too?

Alex A.

Yeah

feersum

Weeks of work.

Dennis

@RetoKoradi You need "B"a #. With two iterables, it searches for sub-arrays, not occurrences.

Alex A.

05:02

@xnor It's unlikely that the majority of golfing discussions will take place outside of here.

xnor

i guess, network effects are hard

Alex A.

And I wouldn't want to discourage people from asking questions like that in here either.

It's just likely that they'll be mixed between the two rooms.

Reto Koradi

@Dennis Yes, that works. For some reason I thought it could directly find an array in an array of arrays. But that doesn't work either, I must be mixing it up with a different operator.

Dennis

e= works like that.

Alex A.

Is e# a comment in CJam?

Dennis

05:05

Yes.

Alex A.

Does Pyth have comments?

Dennis

Sort of. You can prefix a string by a space to prevent auto-printing.

Alex A.

Hm. Okay.

A: Sandbox for Proposed Challenges

Gif - Jif, Jif - Gif The point of this challenge is to (not) settle debate on the pronunciation of "gif" The pronunciation of gif is debated and while it's supposed to be (and should be) pronounced jif, it's still commonly disputed. In this challenge you will be given a set of words that hav...

Justin

@RetoKoradi I have a big problem... I can no longer say GIF with a hard G. I say it "jif".... I can't go back. I've gone off the deep end.

Alex A.

@Justin >:[

Justin

:(

Alex A.

05:17

It's like "GIFT" without the "T."

Reto Koradi

@Justin Well, I don't see a problem. :)

Justin

The problem is that I get people correcting me

Alex A.

Because you're saying it wrong.

Justin

(Although I know I'm saying it how the inventor would like it)

Alex A.

He's wrong.

Justin

05:19

But if it's "jif", then I associate peanut butter with the images!

Alex A.

Which you shouldn't do because Jif peanut butter is crap.

Reto Koradi

Hmm, I thought pretty much everybody said jif. Well, since the format is rarely used anymore, you don't really hear it much anymore.

Justin

@AlexA. Who cares. The name reminds me of peanut butter that is not crap (aka not Jif). Skippy for example

Reto Koradi

oh boy, don't start the peanut butter topic again!

El'endia Starman

Hey, I like JIF peanut butter. And Skippy. Any smooth peanut butter.

Alex A.

05:21

@RetoKoradi I hear it all the time because my girlfriend loves animated GIFs.

Justin

@El'endiaStarman Don't worry. I just said that to appease Alex

Alex A.

@Justin Skippy is crap. You've been living a lie.

El'endia Starman

@RetoKoradi "rarely used"? Have you seen Imgur? :P

Alex A.

@RetoKoradi Too late.

Justin

@AlexA. Have you ever placed a spoonful of Skippy peanut butter in your mouth?

Alex A.

05:23

Maybe at some point.

Justin

It's wonderful

El'endia Starman

Why would you eat that much peanut butter directly!?

Vɪʜᴀɴ

^

Alex A.

I like to just eat peanut butter sometimes.

Reto Koradi

@El'endiaStarman I haven't really encountered a gif in a long time. These days it's mostly PNG or JPEG.

Alex A.

05:23

It's tasty.

@RetoKoradi I thought JPGs had all but died out.

Justin

@El'endiaStarman Because it tastes good. I don't do it much because it's a lot, but my dad does it all the time (well, he would if my mom didn't keep getting irritated at him for doing so)

El'endia Starman

Ever tried it sandwiched between two crackers?

Justin

@El'endiaStarman What kind of cracker?

Alex A.

^ best peanut butter

Reto Koradi

@AlexA. What? Most images on web pages are JPEG, aren't they?

El'endia Starman

05:25

@Justin Doesn't really matter. I use Ritz crackers mostly though.

Justin

Organic PB probably tastes better

@El'endiaStarman Yes, Ritz works well. I don't think saltines would, though.

Alex A.

@Justin Organic probably wouldn't make much of a difference I would think.

El'endia Starman

true

Justin

Fine, but it would make me feel better

Alex A.

I think it's mostly what's in it (I prefer peanuts and peanuts only) and whether and how the peanuts are roasted.

Jif, Skippy, et al. have corn syrup and other non-peanut things in them.

And emulsifiers so that you don't have to stir them.

Justin

05:29

Anyone have halloween costume ideas?

Alex A.

A jar of chunky peanut butter. So chunky it's scary.

Justin

^ My costume

(This has been my costume for the previous two years as well, but I'm going to upgrade it this time)

Reto Koradi

I'll be "airline passenger". Will be on a plane on Halloween. Not really into it anyway.

Alex A.

@Justin I assume π(t, ...) is a differentiable function?

Justin

@AlexA. You are thinking too hard.

Alex A.

05:32

That is rarely true.

If anything I'm typically guilty of the opposite.

DLosc

π is a constant, so it's 0?

Justin

This pun is meant to be really cheesy.

d/dt is the "rate of change"

Alex A.

@DLosc π isn't always a constant. In statistics it's occasionally used to denote probabilities of functions of probabilities.

Justin

I'll be the "rate of change of pi"

Shiver me timbers.

Alex A.

Assuming π = 3.141... then you'll be 0 for Halloween?

DLosc

05:34

As in, "nothing"?

Justin

DLosc

Lol--didn't know we were on Puzzling.SE

@AlexA. 2 8s would be a pair of eights

Justin

@feersum Yes.

Alex A.

I wasn't trying to be right.

Justin

05:38

It's meant to be a terrible pun.

Really terrible pun

"pair eight" = "parrot"

Alex A.

If you're going for math jokes, "pair eight" should be "Pareto."

Justin

@AlexA. This I don't get

feersum

I think two 0s would be closer. Pair aughts.

Justin

We don't even say "naught" here.

So that doesn't work very well.

I'm open for better pirate puns to add this year

Alex A.

Pareto distribution

The Pareto distribution, named after the Italian civil engineer, economist, and sociologist Vilfredo Pareto, is a power law probability distribution that is used in description of social, scientific, geophysical, actuarial, and many other types of observable phenomena. == DefinitionEdit == If X is a random variable with a Pareto (Type I) distribution, then the probability that X is greater than some number x, i.e. the survival function (also called tail function), is given by where xm is the (necessarily positive) minimum possible value of X, and α is a positive parameter. The Pareto Typ...

Justin

05:40

Maybe I cut out 8s from paper and tear them up in front of people?

feersum

You could have two d[pi]/dt. Since they are equal to 0, it would be pair aughts.

Alex A.

Just show up at a party you weren't invited to, stand in the middle of the room, and scream continuously as loud as you can until you pass out.

Justin

@feersum Unfortunately, while making the shirt in the first place, I nearly got high on sharpie marker. Don't want to do that again.

feersum

880

Justin

@feersum ????

What does "880" mean? Is it an emoticon?

feersum

05:45

pair-eight-o.

Justin

Haha okay I thought you were responding to the fact that I nearly got high on sharpie marker while making the shirt.

Maybe I should add an ℝ?

Alex A.

I thought that too so I was trying to make a connection between 880 and 420.

feersum

I like how I can type like eixplicit specilaization in nonnamespcae scope in Google and it still works.

Alex A.

Hahahaha

Why would you type that?

Justin

@AlexA. What is 420?

feersum

05:50

Because I want to search for explicit specialization in non-namespace scope

Alex A.

@Justin urbandictionary.com/define.php?term=420&defid=841517

@feersum I figured as much. But then you should have typed that instead of what you did type. :P

feersum

That's unnecessary extra work.

Alex A.

Within a couple years we'll have brain implants that do Google searches based on our thought patterns without having to type anything.

Typing is unnecessary extra work.

Alex A.

Some of those chocolate chip cookies?

Justin

I like it... but now that I think about it, this deviates somewhat from the math-center.... I'm going to need to think about this.

Is there some concept of "patch" in math?

Alex A.

Uhhhhhh not that I know of.

At least not by that name.

Justin

mathworld.wolfram.com/Patch.html but it's too unknown outside of math

Alex A.

I avoided the upper level real analysis series like the plague. At the University of Washington, they're joint courses between the undergraduate and graduate programs. That was rough.

I did not want to take the other two in the three-course series.

I assume that I would have come across patches in one of those.

Justin

I'll just use an eyepatch with "sqrt(-1)" on it

Alex A.

06:11

√-1

Justin

@AlexA. Yes. But with the overbar

Alex A.

Right

That would make more sense to a larger group of people.

If I set the date last year some time, it could be out by a number of days, in several different ways (since I didn't make a note of the date that I incorrectly entered).

The simplest solution would be to go through each possible date that could have been the day I set the date incorrectly, and see if it is possible to enter the US date in UK format. If so, work out what the input date would correspond to had that incorrect date been entered. Then list all the results

Geobits

I honestly don't know what's that unclear about the old one, except the ugly bonus junk. It's clear enough to me that you need to translate T9 keypresses into text, and it gives the method for doing so.

The only comments about clarity are concerning the bonuses.

the thing was that the OP was going on and asking each answer to implement the bonuses too

as if they are part of the spec and not bonus
