that is not the most disturbing one ...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

wat

Downgoat

(I'm not going to post it if you don't want me to)

ok

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@QPaysTaxes ;D

And on the problems of OS's: if it works fine for the user, it really shouldn't matter what you think of the OS to them.

Martin Büttner

Can we stop with the wat memes? Awesome, I knew you'd all agree! :)

quartata

@MartinBüttner Yes please

Cᴏɴᴏʀ O'Bʀɪᴇɴ

9:08 PM

@QPaysTaxes Well, does it still "work"?

@MartinBüttner wat memes?

Downgoat

@MartinBüttner wat. but we never said yes???

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ a subset of giant one-box gifs

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@QPaysTaxes Well, then it obviously stopped working at that point :P

@quartata I know :P

quartata

@Downgoat I'd hope you'd say yes

Downgoat

wat is wrong with wat memes

Cᴏɴᴏʀ O'Bʀɪᴇɴ

9:09 PM

@QPaysTaxes That's not what I meant by "works".

"works" as in "works out for your purposes"

Martin Büttner

@QPaysTaxes uhhh, not sure if they ever came through, I had already purged the comments when you posted the last one.

CoolestVeto

At least I wrap them in links. >.>

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@QPaysTaxes Still not what I meant by works... It "functions", but doesn't "work" in the sense I just described.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Chat challenge: Write a program that finds the first integer for which exactly three of the following apply:
1. The last digit is 1.
2. The number is divisible by 3.
3. The sum of the digits is 6.
4. The number is prime.

Code-golf, shortest program wins.

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ that is impossible

¬_¬

@QPaysTaxes it is impossible how can a number be prime and divisible by 3

CoolestVeto

Downgoat

@QPaysTaxes Yes it is, and I don't have to run a program.

A: Loopholes that are forbidden by default

Optimising for the given test cases This applies to code-challenges and things like fastest-code, where you write some code that is measured by a criterion like runtime or size of your output (e.g. in compression challenges). These often employ an obviously finite set of test cases, because you ...

@Downgoat no way

that first one isn't even in jelly's code page iirc

Maltysen

@CᴏɴᴏʀO'Bʀɪᴇɴ its probably like 50+1

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Maltysen lel

Downgoat

it's not jelly, just random unicode characters but the Jelly answer willl probably be like that

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Called it!

A: Loopholes that are forbidden by default

Abusing native number types to trivialize a problem It is common practice to restrict challenges to cases where input, output and/or intermediate values of the algorithm of choice fit into the language's native number type. At least for input and output, this is generally assumed even if not sta...

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ that loophole doesn't invalidate my answer

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I know it's a loophole

Downgoat

@QPaysTaxes -1 not JavaScript

Cᴏɴᴏʀ O'Bʀɪᴇɴ

9:28 PM

@El'endiaStarman Isn't hardcoding the output a standard loophole?

Zach Gates

Does -381 work?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

uh

idk

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ For code-golf? I can't recall it being a standard loophole. If hardcoding the answer is possible, that's probably the fault of the question.

Downgoat

@El'endiaStarman Hm, okai

Downgoat

9:30 PM

Zach Gates

@CᴏɴᴏʀO'Bʀɪᴇɴ -3+8+1=6, -381/3=-127, last digit is 1

Cᴏɴᴏʀ O'Bʀɪᴇɴ

No wonder I couldn't find it. I ctrl+f'd "hardcoding"

El'endia Starman

Often, this vulnerability is an indicator of a dumb question... — boothby Mar 7 '14 at 19:37

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Still, it was a chat question :P

El'endia Starman

A *dumb chat question, then. :P

Downgoat

9:31 PM

> downvote the question rather than post a protest answer consisting of the literal output

El'endia Starman

Well, it was a good puzzle.

Zach Gates

Do I win for finding -381

Cᴏɴᴏʀ O'Bʀɪᴇɴ

thank you

Maltysen
