The Nineteenth Byte

@PeterTaylor Are you sure that 228 -> (9,3) in the Hilbert curve question ? I am getting 1,11 and my other outputs are matching with what were present earlier ..

Q: Conditional Operator Broken

I am trying to obfuscate some code for fun, but I have come across some big difficulties: a conditional operator (? :) does not work. Due to the layout of the code and the nature of the Visual Studio Debugger, I cannnot find out whether it is even reached. I have #include <stdlib.h> #include <st...

Optimizer

?

Peter Taylor

@Optimizer That's what my code gets, and that's what my port of MickyT's code gets.

Optimizer

what does your code get for 15 ?

Peter Taylor

(3, 0)

Optimizer

ok cool. But I think you cannot use Infinity in your code

in the while loop parameter

Peter Taylor

2:01 PM

I'm not, no

Optimizer

ok

I am getting all right values except for some weird cases

u gonna post urs ?

Peter Taylor

When it's golfed

I'm still trying different approaches

Optimizer

hmm, even the C implementation on wikipedia gives swapped X and Y depending on the value of n

Peter Taylor

Oh, MickyT's code is just a port of the code on Wikipedia? Boo

Optimizer

u didn't realize ?

just that it replaces n with Inf

and ur code is port of MickyT's ? :P

Peter Taylor

2:11 PM

No, I wrote a direct implementation. I also ported MickyT's for comparison.

Optimizer

recursive ?

Peter Taylor

Iterative

Optimizer

is it much different from MickyT's ?

Peter Taylor

I've been trying to find a simple form for the x-coord because I've found a simple form for x^y. So far no luck.

Extremely. When I say "direct implementation" I mean an implementation of the generation process described in the question

Optimizer

if you do find, it would be nice to update wikipedia too ^.^

I'm trying to golf my regex comparison under 1000 bytes and it is tough...

Sp3000

I'm still of the opinion that that question shouldn't be code golf :P

But objective winning criteria, I guess

feersum

why not?

maybe zlib will help me

Sp3000

It's hard enough to be a good code-challenge imo

feersum

don't think i've ever used a zip answer

feersum

2:56 PM

woohoo down to 981 bytes!

Sp3000

:o by zipping?

feersum

no haven't zipped yet

I should try to make all the variables have the same name so it can zip better

Martin Büttner

3:37 PM

@Sp3000 your new results are absolutely gorgeous

Sp3000

I implemented the Gaussian filter naively for testing so results are taking a while, but once I'm satisfied I'll start making it more efficient :P

Martin Büttner

I mean even without the smoothing

Sp3000

Ahaha right :P

I do wish HNQ wasn't scored with such a big penalty on question age though :/

Optimizer

its not built to keep in mind of PPCG

Sp3000

It'd be interesting if they accounted for, say, a question which is a year old but suddenly got 10 answers overnight :P

Ahaha yeah...

Martin Büttner

3:39 PM

@Sp3000 I agree

Optimizer

which is diff. from other SE where question age is a huge contribution

Martin Büttner

@Optimizer actually PPCG is doing really well on the HNQ

Sp3000

Favicon's on there atm from memory

Optimizer

that's for other reasons, but the algorithm doesn't really fit for PPCG where things are not really questions, but challenges.

Martin Büttner

@Optimizer a lot of things don't really fit for PPCG

Sp3000

3:42 PM

Same goes for Puzzling I guess (that's probably half the source of their problems, tbh)

Martin Büttner

I think if it got another two or three answers today with a reasonable amount of votes, it might still make HNQ, but that's unlikely. (print a negative was on there for over a week)

Sp3000

Ahaha I guess there's also the momentum factor...

I tried looking for 2-day-old questions... there was one, upvoted about 40 times and most upvoted answer about 80

Martin Büttner

well you can't compare it with other sites

the hotness value is scaled by site traffic

Sp3000

Ah :/

Martin Büttner

and also, within each site, the second hottest question gets devalued a bit, and the third hottest even more and so on

(which was probably another factor in not making HNQ because both print a negative and the one with the french nouns were still in there)

Sp3000

3:47 PM

Are they? I don't think so any more...

Martin Büttner

not any more, no

but they were

feersum

it's time to take rep wars to the next level!

make botnets for viewing own questions!

Martin Büttner

lol

could someone have a final glance at meta.codegolf.stackexchange.com/a/2560/8478 before I post it?

Sp3000

Ahaha Martin's singlehandedly posting all the good questions this week :P

Martin Büttner

someone's gotta do it if Calvin's Hobbies is in hibernation...

(not that mine are anywhere near his quality)

actually I wanted to lift the ban on built-in string splitting functions

Sp3000

3:53 PM

"Neither program/function must contain any string or regex literals" Neither program/function may?

Not sure, but it sounded weird

feersum

right, should be may

Martin Büttner

you're the native speaker... I'm taking your word for it :P

neither may vs. neither must vs most not vs may not... I'll never get it :D

Optimizer

"Both program/function must not contain" is another alternative

Martin Büttner

yeah, basically "must not" is weird and all the others make sense, but it took me years to get "must not" into my head that I'm not switching up the others too :D

Sp3000

It's something to do with the fact that "must contain" sounds affirmative, while "Neither" is negative

Optimizer

3:55 PM

must not in my line is ok

Martin Büttner

@Optimizer yes it's right (in English), but it doesn't make any sense to me :D

Optimizer

but the sense of the two versions change, must implies a forced rule, may implies a normal rule :D

(maybe ? )

Martin Büttner

okay, let's do this. thanks for the feedback guys

Optimizer

Do we really have to print each string on new line in case of STDOUT ?

Martin Büttner

yes

Q: Significant Whitespace

We define whitespace to be any of the three characters, tab (0x09), newline (0x0A) or space (0x20). For this challenge, you're to write two programs or functions in the same programming language, which perform the following tasks: Count the whitespace in a given string. For instance, the input...

Sp3000

4:00 PM

Hmmm the first thing I can think of to solve it would be variable assignment as comments

(thinking about Python, as usual)

Optimizer

printing like ["asd" "fggh"] would have been easier :D

Martin Büttner

@Sp3000 what do you mean?

@Optimizer for you...

Optimizer

obv

I guess its just 1 extra byte

lets see

Sp3000

a=afoo=1
x=a
foo

v.s.

a=afoo=1
x=afoo

Or something

Martin Büttner

@Optimizer you can always make it a block instead

@Sp3000 ah I see

Optimizer

4:03 PM

a block ?

Martin Büttner

@Optimizer well then you can "return" an array

Optimizer

okay.. lets see, first draft is ready ..

Martin Büttner

btw, I found this on reddit today: aphall.com/2014/12/glsl-projectron

it's amazing

Sp3000

@MartinBüttner I'm assuming string literal means I can't do x.count(" "), but what about x.count(chr(32))?

Martin Büttner

@Sp3000 the latter is fine.

Sp3000

4:06 PM

"Oops! Looks like WebGL isn't supported :("

What.

Optimizer

what ?

Sp3000

I used WebGL for my project last year!

(For Martin's link)

Optimizer

what browser ?

Sp3000

Chrome

Optimizer

my question was more of surprise

Martin Büttner

4:08 PM

it's basically like that challenge idea I had a few weeks ago... just better :D

(this idea chat.stackexchange.com/transcript/message/18116715#18116715)

@Sp3000 my idea for python was that you could just outdent a statement in an if False:

Sp3000

Haha that might work

Another idea I had could be short circuiting

Martin Büttner

@Optimizer 1 0 gives you a truthy/falsy result in 3/2 bytes, but it leaves a 1 on the stack in one case.....

Optimizer

edit it one more time!

I dare you

Sp3000

(On a side note, amazingly blurring still kept some the stars from N=500, P=30. I thought they'd be annihilated)

Optimizer

@MartinBüttner why are you doing this to me ? ;)

Martin Büttner

4:19 PM

;)

Sp3000

(they're a lot smaller though...)

Martin Büttner

this is spamming for psychopaths :D

Optimizer

@MartinBüttner I got a shorter one!

Martin Büttner

nice

Optimizer

now that filter is bothering me so much

i wanna kill it

@MartinBüttner can there be 0 Whitespaces ?

Martin Büttner

4:30 PM

yes

Optimizer

wow, people do hate CJam :D

Martin Büttner

why, did you get downvoted somewhere again?

Optimizer

no, I am not getting upvoted on this answer

whitespace one

Martin Büttner

well, most people can't read CJam... why would anyone upvote code they don't understand?

feersum

phew finally posted regex compare

584 bytes lol

Martin Büttner

4:37 PM

@Sp3000 lol, I love the s*0

feersum

s*0?

Sp3000

Assume that was at me, but :P you didn't let me empty string

Martin Büttner

@Sp3000 also, commas ;)

Sp3000

Commas?

Martin Büttner

in the header

the snippet needs a comma too figure out where the language name ends

Sp3000

4:38 PM

...oh right I forgot there was a format

Martin Büttner

don't worry ;)

Sp3000

Thanks :)

Optimizer

4:50 PM

I guess, most languages will do the variable name trick only.

Sp3000

Oh right, Martin allowed builtins now?

Martin Büttner

yup

Sp3000

That makes things shorter

Optimizer

Oh!, I can use split !

damn

Martin Büttner

bam, HNQ

Sp3000

4:58 PM

I look forward to the incoming upvotes :D (I like my new solution)

Martin Büttner

not sorted :D, that's amazing

you could save 8 bytes though, right? :P

Sp3000

Can I?

Martin Büttner

or is sorted a built-in?

Sp3000

sorted is a built-in function

I need the not to convert to bool for indexing

Martin Büttner

but so is sort, right?

Sp3000

5:01 PM

That's .sort()

Martin Büttner

oh okay

Sp3000

There's also format and memoryview. If I can figure out how to use ord that could be a way

i bought $230 headphones online yesterday and now i'm stalking the shipment status page the whole time

Optimizer

Audio technica ?

cjfaure

@Optimizer Shure SRH840s actually

they're $230 because of import fees and such

Optimizer

hmm. never heard of Shure

Martin Büttner

5:33 PM

@cjfaure i know that feel bro

cjfaure

@MartinBüttner it's been 24 hours over a workday and they're still "unshipped" D:

Optimizer

which site u ordered from ?

cjfaure

@Optimizer soundz.co.za, shady as hell but the only local place

Optimizer

I have bought from such shady sites..

first time is always risky

cjfaure

buying from amazon would have worked out to be around $300 though

Optimizer

5:37 PM

I guess u guys dont have better and cheaper local competitors to amazon

Rainbolt

Often I find that my orders go from unshipped to my doorstep in a matter of hours. Sometimes I even get notices that my order has shipped after I already have it in my hands.

cjfaure

@Optimizer it's not possible, nothing is made here (except Toyotas, but they're sold at the same price because profiiit) and the import fees are insane

Optimizer

where is here ?

cjfaure

south afric

a

(that moment when your up arrow decides to not work)

Optimizer

I see

cjfaure

5:39 PM

@Rainbolt the post office is on strike here also, so that doesn't help

Rainbolt

(that moment when you realize that the up arrow is a hotkey)

cjfaure

and the site didn't have a courier option

Optimizer

@Rainbolt you live near one of the store houses of that site ?

As I told @FryAmTheEggman yesterday, I can do a <60 ! :D

cjfaure

I can do a 180, but I don't want to break my neck

(i'm wondering if the shipping or the burn-in on the headphones will take longer)

Martin Büttner

@cjfaure hrhr

5:45 PM

@MartinBüttner you're dad's dad's jokes

Rainbolt

@Optimizer No, I ordered something from Tokyo, Japan. I live in the US. It was supposed to arrive after two weeks. It arrived in two days. After two weeks, I got a notification that my order had shipped.

Optimizer

in 2 days !!!

:O

also, I was talking about the case where the shipment arrives in hours.

Geobits

@Rainbolt I've gotten that in reverse while living in Tokyo. It always baffled me.

Optimizer

I guess they treat Americans special. I order from Tokyo/China all the time, didn't even get in less than 10 days once

cjfaure

"i guess they treat americans special"

Rainbolt

5:48 PM

@Optimizer The online tracker moves from unshipped to my doorstep in hours. It didn't actually do that in real life. They just update their system slowly.

Optimizer

:D

Rainbolt

I have a feeling that I actually paid outrageous shipping fees just so that they could call their American factory and say "Hey, can you ship this for us?" I bet it didn't even come from Tokyo.

Optimizer

lol

which site ?

sites like these generally dont have store houses at all.

cjfaure

reading the user manual pdf for the headphones on the shure site

"WARNING: This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm."

is it Zomboy?

you still ordered ?
