A: Sandbox for Proposed Challenges

Count the Matchsticks code-golf what other tags? Most people here are familiar with seven segment displays, which are also used in matchstick puzzles. Below are the digits 0 through 9 and negative sign - written in this format. _ _ _ _ _ _ _ _ | | | _| _| |_...

@NewSandboxedPosts Hmm, I smell compression (when posted)

Mr. Xcoder

I smell brute-force

caird coinheringaahing

Nah, just take digits, then lookup the amount needed for each digit, then sum

Mr. Xcoder

I can guarantee you that there's something shorter than that :P

caird coinheringaahing

20:38

I'm not going to go any further, lest I actually try and solve it :P

caird coinheringaahing

Huh, I joined SO and CR on the same day, but PPCG 9 days before. Weird

Mr. Xcoder

I joined SO 4 months before and I have ~22k less rep there :P

Anyway, my rep is very satisfying atm, 24860

All-even.

caird coinheringaahing

I just reached 10k network rep, and the first flag I saw in chat disappeared as soon as I clicked on the icon :(

@cairdcoinheringaahing Get used to it. That's what happens everytime

Mr. Xcoder

Not to me?... That happens to me in the review queues though, so we're on par :P

caird coinheringaahing

checks review queues ... Nothing

Mr. Xcoder

We need a challenge to check if the review queue is non-empty :p

And good news ^_^ I started developing Cthulhu again, after having abandoned it

Erik the Outgolfer

lol just click the review button on the top bar

Mr. Xcoder

way too much work :P

caird coinheringaahing

20:47

Or just ask DJ cause he seems to live in them :P

Erik the Outgolfer

if you get to

DJMcMayhem

@cairdcoinheringaahing checks review queues ... Nothing

Mr. Xcoder

I don't see how PPCG is so inactive sometimes and the review queues are empty all the time, but whenever something appears everyone else seems to be just there and boom it's not there anymore

@MartinEnder -1 that implies abuse

huh?

"stalk"ing isn't a good thing

Q: Review Stalker Reloaded: A cross-site dashboard for reviews

About Based very loosely on the Review Stalker user script, this script has been rewritten several times since then. Its purpose is to be a one-stop pinned tab, always checking for review opportunities on main and meta as aggressively as is useful between multiple sites you configure. Usage...

Erik the Outgolfer

shouldn't have mentioned that... :P

caird coinheringaahing

@MartinEnder That looks helpful (and explains DJ's constant reviewing)

Mr. Xcoder

20:59

@DJMcMayhem That fails if an element occurs multiple times, right? Anyway, you can save a byte by using x-l.index(x)for instead

DJMcMayhem

@Mr.Xcoder You're right

Erik the Outgolfer

@Mr.Xcoder wait, do you go up the transcript regularly?

Mr. Xcoder

In this case, I have the CMC widget installed and I have looked a bit below the CMC. But I usually do when I have time, sometimes.

caird coinheringaahing

Yeah, I was thinking that was a kind of random message to reply to :P

DJMcMayhem

CMC widget?

Mr. Xcoder

05AB1E, 3 bytes ā-P (1-indexed)

Returns 0 for truthy, any other integer for truthy.

My personal favourite is 4 bytes though: ƶÅ²O. Assumes the elements are non-0... 1-indexed. ƶ – multiply each by its index; Å² – check if it's a perfect square; O – sum

Erik the Outgolfer

I don't think you can do that

but appending a > will fix it

Mr. Xcoder

I did provide a correct solution, the latter was just for fun.

Erik the Outgolfer

I'm talking about the first (3-byte) solution though

Mr. Xcoder

Why exactly?

caird coinheringaahing

@Mr.Xcoder Having a builtin for "multiply each by its index" seems ridiculous, but it actually looks really helpful at times

Mr. Xcoder

21:17

I meant Returns 0 for truthy, any other integer for falsy. btw

Erik the Outgolfer

05AB1E's if/else construct for testing is i1ë0}, and only 1 passes the test

Mr. Xcoder

Eh, you're too pedantic for a CMC :P

caird coinheringaahing

Can I borrow someone who's using the gradscript to test something quickly?

totallyhuman

sure

Mr. Xcoder

Yeah

caird coinheringaahing

21:20

Go here and check your Achievements

Mr. Xcoder

Achievements?

totallyhuman

yeah and?

caird coinheringaahing

Does the PPCG logo show?

totallyhuman

ah yeah the gradscript's not acting on it

caird coinheringaahing

How about here?

totallyhuman

21:21

nope

Mr. Xcoder

It shows the regular logo

Erik the Outgolfer

@Mr.Xcoder it's like saying "this adds two numbers, but, eh, there's a little issue, that the result is off-by-one, trivial fix"

caird coinheringaahing

@Mr.Xcoder Even for the second link?

Mr. Xcoder

Yes

caird coinheringaahing

No, click the icon where you'd see your rep changes

Mr. Xcoder

21:22

Oh...

It shows something blurry

Kinda like random blue lines

caird coinheringaahing

This?

Mr. Xcoder

Similar

Like this

caird coinheringaahing

Hmm, weird. Is it worth reporting?

ETHproductions

@cairdcoinheringaahing I see this too

Mr. Xcoder

I've actually noticed that for a long time yet I didn't know what you meant by Achievements facepalm

Q: Three-Dimensional Chess

In order to defend someone’s baffling decision, people often say that that person is going over everyone’s heads and playing “3-dimensional chess”. Now it’s your chance to play 3-dimensional chess! Rules There are many variants of 3D Chess, but for this challenge I’ve made up my own. My version...

30: Pop current stack from the stack stack.

I love stacks

ATaco

Stacks are great fun

Destructible Lemon

oh i should have checked the history on the answer

moonheart08

@ATaco What about recursive stacks? :)

Leaky Nun

@Adám 大道至簡: 大 - big/great; 道 - way (the same word for Tao in Taoism); 至 - [superlative]; 簡 - simple/concise

it means that the great truths are [often those that are] the most concise

Adám

@LeakyNun Thanks. So is it OK to translate it as "The greatest Tao is the simplest one"?

Leaky Nun

22:24

well it isn’t really talking about Tao is it

i don’t know about the context

Adám

@LeakyNun I'm going to use it in the context of something called TAO.

Leaky Nun

oh lol ok

@Adám yes then

Erik the Outgolfer

lol what a coincidence

Adám

@LeakyNun The idea being that we've tried designing our "TAO" to be as simple as possible.

Leaky Nun

lol

22:26

@moonheart08 :|

Leaky Nun

oh and you might want to know that the text you gave me is in traditional chinese

Adám

@LeakyNun Yeah, I know. It kind of have to be for it to be a traditional proverb, no?

moonheart08

@ASCII-only You have been recursed.

ASCII-only

@moonheart08 you're turning a stack-based language into a scope-based language :/ (well, kinda)

Adám

@LeakyNun And Google Translate does a horrible job with it… "Avenue to Jane"(!)

Leaky Nun

22:27

@Adám eh... people in China learn proverbs just fine using simplified Chinese :p

@Adám that’s because proverbs like this are written in a more concise and literary language

moonheart08

@ASCII-only I adhere to zero standards, so don't be suprised

Leaky Nun

called... classical chinese i think

Erik the Outgolfer

just the other day, somebody was entering massive insults into Google Translate, and the result was "Hey you"

ASCII-only

@EriktheOutgolfer maybe they typed it wrong? :P

moonheart08

@EriktheOutgolfer Hey you

That's insulting, right?

ATaco

22:32

@moonheart08 that’s RProgN’s data model

Bubbler

23:11

May I ask some feedback for this challenge on sandbox?

Destructible Lemon

@Bubbler I think it's pretty clear? i'm not sure

ATaco

Might be a duplicate of that other polyglot one.

Destructible Lemon

yeah, maybe

so uh, is it no longer required to mark answers non-competing or something?

ATaco

Languages can be newer than the challenge now, assuming the feature wasn't implemented for the challenge.

Destructible Lemon

reminds me of this answer of mine

i actually managed to do some compression though, which was pretty cool

Man that challenge was a surprisingly tough one.

Destructible Lemon

i think the fact that i actually managed to get it smaller was pretty nice... it was my first answer in Turtlèd... also like the only time it was good at ascii art really
