@NewMainPosts DJ, didn't we already have a challenge like this?

I can't seem to find one now, though.

DJMcMayhem

@AdmBorkBork Are you thinking of this?

Reminds me of another challenge where we had to, I think, vertically repeat a character by its index in the alphabet. — Shaggy 47 mins ago

Caird thought it was a dupe too, but no one could find the original

AdmBorkBork

Oh, that could be.

It's just that Hello World example looks really familiar

Jeez, Martin just got smoked.

@AdmBorkBork BTW

One to go...

AdmBorkBork

lol

DJMcMayhem

I need #100 to be my best one yet

AdmBorkBork

readies dupehammer

caird coinheringaahing

@DJMcMayhem Do you know how close you are to maintaining a good question record?

DJMcMayhem

Well over

caird coinheringaahing

7:46 PM

Now I'm intrigued. The formula for finding it (in case anyone cares) is:

(total questions - negative questions - closed - deleted)/total questions >= 0.5

DJMcMayhem

@cairdcoinheringaahing Out of 104 questions, I have 3 deleted, 1 negative, 5 closed

caird coinheringaahing

Counts repeat, so a downvoted, closed, deleted question would subtract 3 :/

DJMcMayhem

So my percentage would be 91% which is well over 50%

caird coinheringaahing

Oof, that's high. I had a bad streak of questions when I was a sub-1k user, so have something like 15% D:

AdmBorkBork

Hey DJ, isn't your Word Icicle! test have the e and d removal backwards?

The 'e' is removed before the 'd' is.

DJMcMayhem

7:51 PM

Uhm... No it isn't. I don't know what you're talking about. And I certainly didn't just edit to fix it right now >_>

AdmBorkBork

Riiight. :D

DJMcMayhem

I don't make my test cases by hand, what are you talking about <_<

AdmBorkBork

I'm just surprised no one else spotted it.

lol, your "I'm Melting!!!" test case has a duplicate "I m Melting "

J. Sallé

@DJMcMayhem also are lines 5 and 6 from the I'm Melting!!! example supposed to look the same?

DJMcMayhem

sigh

Cows quack

7:54 PM

@DJMcMayhem is it okay if we have a trailing line full of spaces in output?

(where #spaces = len(input))

J. Sallé

My apl answer does have that, I assumed it counts as a trailing newline

Soaku

How I love that Markdown uses backticks for code... `⥿`

My codepage looks just funny

DJMcMayhem

@Cowsquack Since trailing spaces on the other lines are fine, I don't see any reason to disallow that. How should I phrase that rule?

Cows quack

"You may have one trailing line of whitespace, but not more." ?

yeah that doesn't really sound nice

DJMcMayhem

Yeah, saying "empty line" sounds fine, but "Empty or containing up to len(input()) spaces" sounds really awkward

@Cowsquack Are you going to answer in V? :P

Cows quack

8:02 PM

I chose sed :P

AdmBorkBork

Gah that replace syntax is weird in PowerShell

DJMcMayhem

I can't clear my notifications :/

AdmBorkBork

Soaku

what

if you keep it open for a while and close, it doesn't hide them?

@Lynn Canvas, 16 bytes. Fixed a stupid bug for this to work

AdmBorkBork

Yay, Rainbolt found the pseudo-dupe.

What is the volume of a disk with radius z and height a?

H.PWiz

pi*z*z*a

orlp

use \*

and yes!

H.PWiz

Sorted. (also pizza)

DJMcMayhem

8:25 PM

@orlp Pi * a * z^2 :P

Piaz?

FWIW, I think they look more like icicles than rain — caird coinheringaahing Oct 10 '17 at 18:39

@DJMcMayhem I knew there was a similar challenge!

@DJMcMayhem What badge did you get? I'm guessing Nice Question?

DJMcMayhem

8:51 PM

Yep

ETHproductions

Good to see the old @NewMainPosts on the starboard again ;-)

Dennis

9:13 PM

@orlp Since a = 0, zero. :P

Pavel

@Dennis I don't know about that

Dennis

9:37 PM

Many programming languages use = entirely wrong.

Pavel

I actually read an article on hn about that just now

> For mathematicians, = does not mean equality - news.ycombinator.com/item?id=16833391

flawr

@Pavel thank god I'm not a mathematician, it would really suck if = meant inequality

Dennis

9:58 PM

@Pavel It does mean equality in math. In C, = it's a store operation that doesn't exist as such in math; == is equality.

caird coinheringaahing

Any feedback?. Feel like posting tomorrow

dylnan

If a certain prefix outputs 1, should the corresponding suffix also output 1?

caird coinheringaahing

Yes

Is that not clear in the spec?

dylnan

10:13 PM

It's not unclear, I was just making sure

It looks really hard. You could consider changing it so that the output of prefixes/suffixes can depend on input but keeping the rest of the rules the same. That would make it easier and doesn't really change the spirit of the question

caird coinheringaahing

I'm intending it to be really hard. I might draft an easier version, but I want to make a challenge where I'm not expecting an answer within a week of posting

dylnan

Even without consistent prefix output requirement I think it would be really hard

dylnan

10:32 PM

Does anyone know if there has been a challenge on Clebsch-Gordon coefficients? I'm thinking of writing one but worried the challenge will be too hard

caird coinheringaahing

ಠ_ಠ I just posted, then immediately deleted a challenge (wasn't finished). Reckon NMP will post a link?

dylnan

What is NMP

caird coinheringaahing

New Main Posts. The feed that posts new challenges into the room

Scrooble

@cairdcoinheringaahing Wow, that's tricky. I like it.

Q: Generalise "Do X without Y"

Do X without Y challenges are notoriously difficult to do well, yet now we're going to make a program to generalise such challenges, so that you'll always be prepared in case one appears. Here, when I refer to a "string", this also covers a list of characters, or a list of integers representing ...
