@DJMcMayhem Where is that info? In your profile somewhere?

@Riley You can't see others' consecutive day counts (or even total day counts). The closest you can get is looking for the presence or absence of the Fanatic badge.

Riley

Sorry, I meant where can I see my consecutive day count.

ETHproductions

Is this sandboxed post ok for posting?

Wheat Wizard

I probably wouldn't VTC

ETHproductions

Peter Taylor points out that it's uncomfortably close to this recent challenge, but I think it's ok (mainly because the task is much simpler).

heh, reverse-ninja'd

Is it too trivial though?

Wheat Wizard

Probably not

I would say its a nice sweet spot where it is rather easy but not to trivial

Sami Altamimi

what about this

I might be biased though, because all I think when I see it is "I can do that in Brain-Flak"

DJMcMayhem

@ETHproductions I like it, but this part is a little weird:

truthy/falsy value, or any two constant, distinct values.

Shouldn't it be one or the other?

ETHproductions

It's a compromise between the two options, since which is shorter really depends entirely on the program. (I'm saying you should choose between one or the other, not do both with the same program)

Would it be better off with just one or the other?

DJMcMayhem

:shrug:

Riley

@ETHproductions I like the option to choose either.

DJMcMayhem

@WheatWizard I know brain-flak is good at generating triangular number, but detecting triangular numbers sounds like a pain. What would you do? Something like generating the n-th triangular number until it's larger than the input?

Then push difference and NOT?

Wheat Wizard

7:34 PM

Probably subtract an increasing number from the input until less than 1

then not

DJMcMayhem

Oh, that's much better

ETHproductions

@Riley That's what I thought; I don't like challenges where it's one or the other quite as much, because the non-chosen option may be shorter than the chosen option

Wheat Wizard

@ETHproductions It does allow for this terrible answer though

ETHproductions

@WheatWizard Wait, what? How is that a valid answer?

pls cough codegolf.meta.stackexchange.com/questions/2140/… cough peddling is hard enough

ETHproductions

@WheatWizard Never mind, the code was messed up. The print f(5) showed up in the input instead of the footer

Wheat Wizard

Yeah just fixed the link, my bad

ETHproductions

also you never define f :P

oh, there you go

Wheat Wizard

I have to say I am not a big fan of truthy/falsy.

I think it makes challenges worse

ETHproductions

Now I am not a fan either

Sami Altamimi

7:40 PM

i didnt even know what it was

ETHproductions

@WheatWizard Better?

Wheat Wizard

I like it that way :)

@Riley @DJMcMayhem Anyone want to duel me at ETHproductions question? I'd be happy to put rep on it.

In Brain-Flak of course

tuskiomi

What do you think of an "I like the ____" (boomdeyadda) challenge?

Sami Altamimi

7:53 PM

@ETHproductions should i put code-golf or popularity contest

ETHproductions

code-golf for sure. pop-cons are incredibly hard to get right

I think we may have had one or maybe two pop-cons in the last year that were not quickly downvoted and/or closed

Sami Altamimi

i want to get a second opinion about the formatting issue

@WheatWizard codegolf.meta.stackexchange.com/questions/2140/… help us out in discussing this issue

Riley

@WheatWizard I'm up for it, but I'll need a few days to come up with a solution. I'm pretty busy now. We could do a three person duel, winner takes all, if DJMcMayhem wants to.

Wheat Wizard

Ok yeah, I think a few days is a good idea anyway

ETHproductions

@Sami Here's a tip for improving challenges in general: codegolf.meta.stackexchange.com/a/9384/42545

Wheat Wizard

7:57 PM

@SamiAltamimi I agree with ETHproductions, if you keep the formatting that becomes the entire challenge.

Sami Altamimi

so what should i change it to

or use his suggestion

Wheat Wizard

I think his suggestion is pretty good

Sami Altamimi

alright

Wheat Wizard

flexible output is a plus

ETHproductions

I suggest changing the output rule to "You may output the results in any reasonable format." if you want an exact wording

Wheat Wizard

8:00 PM

^ I do that a lot myself. Cumbersome IO can really be annoying, and you can't really accommodate every language when you are writing the challenge. So just let people figure out what makes sense. If something is iffy most people will ask about it.

Sami Altamimi

fixed it up a bit

ETHproductions

"However, I do want" sounds a bit subjective. Perhaps "You may output the results in any reasonable format, as long as it includes the website name, status codes for all the websites and the redirects"

Riley

@WheatWizard How much rep were you thinking for the duel?

ETHproductions

8:15 PM

I'm going to get off in a moment... should I post the challenge first so you guys can start?

Also, is it too close to codegolf.stackexchange.com/questions/121731/… in your opinions?

Wheat Wizard

@Riley 100 seems good

We can't do any less and I'd rather not do any more

@ETHproductions I don't think so

Christopher

@WheatWizard Later I wanna duel in Newline (or anyone else)

But mainly you to settle it for once and for all

Riley

@WheatWizard 100 sounds good to me. Why couldn't we do 50?

Christopher

He has placed a bounty on it before for 50

Riley

The challenge hasn't been posted yet.

Wheat Wizard

8:22 PM

The minimum for a question you have answered is 100

Christopher

Ah makes sense.

ETHproductions

Should I throw in a "your code must finish in under one minute for all inputs in range"?

I don't know that it improves the challenge any

Wheat Wizard

IMO no, its not observable and it penalizes slower languages

ETHproductions

Right, that's what I was thinking

Riley

I don't think it does, and Brain-Flak can be really slow sometimes :P

Jan Dvorak

8:26 PM

Is the algorithmic complexity observable? I think it is.

ETHproductions

Alright then, posted. Have at it

Wheat Wizard

@JanDvorak I'm pretty sure its not, finding a source now...

Riley

@ETHproductions Does no output count as a constant, distinct value?

Wheat Wizard

IIRC there are algorithms we don't know the time complexity

Jan Dvorak

I can't see a reason why it wouldn't be well defined per code

ETHproductions

8:28 PM

@Riley Yep, as the empty string

"distinct" just means the two outputs should be different though

Wheat Wizard

@JanDvorak Doesn't something need to be computable to be observable?

Helka Homba

CMC: Find a downside to Kotlin, JetBrains' (and now Google's) fancy new language meant to kinda replace Java.

Jan Dvorak

If you can't bound the time complexity of your code, you can't use it in bounded-complexity challenges

@WheatWizard you can't tell for arbitrary code if they even return the correct result either

ETHproductions

@HelkaHomba Does "it's not Java" count? :P

Wheat Wizard

@JanDvorak Yeah, hence why a program working is non-observable

Jan Dvorak

8:30 PM

And yet challenges habitually require that the code works

Helka Homba

@ETHproductions Some would call that an upside :P

3

Wheat Wizard

@Riley What type of duel are we doing? Are we going to do a back and forth or are we going to wait a while and then reveal simultaneously?

Jan Dvorak

@HelkaHomba platform-dependence?

ETHproductions

Aw sweet, it has operator overloading

Helka Homba

@JanDvorak it's like 100% interoperable with Java (and JS I think)

Like it runs on the JVM and can be mixed easily with Java projects

ETHproductions

Alright, I've got to head out now. Talk to y'all later

code-golf number decision-problem

Helka Homba

I like how one arg lambdas can just use it as the input

val times3: (Int) -> Int = { it * 3 }

Riley

@WheatWizard I like the idea of revealing at the same time. When we did the Flak/Flueue quine we went back and forth and it kind of came down to who happened to get the last improvement. Either of us could have won that one.

@totallyhuman that too

Riley

We can do whichever one you want though.

Wheat Wizard

I have strong opinions both ways. We can go with simultaneous reveal

Phoenix

@HelkaHomba fun main(args: Array<String>) is absolutely godawful. As is var foo : int. Though the designers of VSL likely disagree, I'll stick with normal function and variable definitions. None of this hipster stuff.

I like all of the features and ideas but the syntax isn't for me.

Wheat Wizard

should we schedule a date or just play it by ear?

Erik the Outgolfer

@WheatWizard almost nobody has a life here afaict...

Helka Homba

@Phoenix You mean you prefer plain int x = 8;? Fair enough, though kotlin does lots of type inference, like val x : Int = 8 is the same as val x = 8

Phoenix

Type inference is fine, I've gotten fond of C#'s var. But sometimes you need to state a type explicitly and Kotlin's syntax bothers me. It's more so the function syntax tho.

Riley

@WheatWizard I think we can just play it by ear. Do you want to wait to see if @DJMcMayhem wants to duel too? We can't place 2 bounties at the same time, but we could do 2 short ones.

Wheat Wizard

We can wait for his response.
