Jelly, 4 bytes ŒḄ¡S Try it online! or verify all test cases. How it works ŒḄ¡S Main link. Argument: n (integer) ŒḄ Bounce; turn the list [a, b, ..., y, z] into [a, b, ..., y, z, y, ..., b, a]. This casts to range, so the first array to be bounced is [1, ..., n]. For example,...

PhiNotPi

Anyone else hyped for January 6th, 2018?

ETHproductions

Give me a reason and I might be

DrMcMoylex

Why?

PhiNotPi

1/6/18 Phi Day

Maltysen

hahahaha

ETHproductions

00:18

I'll celebrate that with apple phie, of course

DrMcMoylex

I'm obsessed with this song right now

ETHproductions

So I've got the following 9-byte Jelly submission to "Print a letter Fibonacci":

”bṄ;@¥¡”a

It works perfectly, except that it starts with b and not a, and prints one too many items. Anyone know how to fix this?

Helka Homba

CMC: Help me find why the little number to the left of each playlist item like "20" is missing the the HTML source of youtube.com/playlist?list=PLb5f0M4WXZjzv8tGZnNqqNbpPRvF7LnJR . I only see <td class="pl-video-index"></td>

Maltysen

@HelkaHomba imma guess content css directive on the pseudo-element

ASCII-only

Look for ::before and ::after

Maltysen

00:27

yup

index:before{content:counter(playlistvideo);counter-increment:playlistvideo}

Helka Homba

Ok. CSS is strangely capable ._.

ASCII-only

Yeah, did you know CSS has variables (well, at least for chromium)

the calc css function is pretty powerful as well

Maltysen

@ASCII-only but also disappointingly lacking sometimes

ASCII-only

@Maltysen yeah :(

Helka Homba

@ASCII-only Someday we won't even need HTML or JS...

ASCII-only

00:31

@HelkaHomba ~~yes everyone will be using VSL for content + VSL for style + VSL for scripting~~ nvm too unrealistic for a language made by PPCG

ETHproductions

@HelkaHomba Trippy thought: someday we won't need PPCG

Geobits

We don't need it now. We want it.

ASCII-only

Some day we'll need codegolf instead

Geobits

(something something blasphemy)

@Dennis Again?

Oooh it was Alex. Everything is clear now.

No, that was typed exactly as intended. Thanks for the effort, though.

mınxomaτ

Oh wow, the polls are at 45/45. That is very decidedly undecided.

Geobits

00:36

Geobits problems: I'd like to change my avatar, but I don't want to leave the nice downstar pun on the starboard without context :/

Luis Mendo

@Dennis 4 bytes :-o

ASCII-only

@Geobits Use Minibits as a sock :P

Geobits

@mınxomaτ Am I reading that right, that it's simply the median of the latest five national polls? If so, I'm not sure how much stock I'd put in it.

mınxomaτ

Well, it's better than any one poll on it's own.

Looking at the sources (bbc.com/news/election-us-2016-37450667) it's pretty balanced

(pun not intended)

Alex A.

Puns are always intended

Geobits

00:39

That looks really unbalanced to me though o_O

mınxomaτ

What source is missing in your opinion - and why?

Geobits

Oh hey there birdman

mınxomaτ

@Geobits He posted and left immediately.

Maybe he has to fly south now.

Geobits

@mınxomaτ No, I mean looking at the list of polls, there are far more (recent and otherwise) that show Clinton ahead than tied or losing. I assumed by 'balanced' you meant mostly tied or a similar number of "wins".

mınxomaτ

No, I mean source-wise.

Geobits

00:42

Gotcha. I don't know enough about the individual pollster's usual numbers to give an informed opinion of that.

mınxomaτ

It's still pretty impressively close.

Helka Homba

@AlexA. Hello. Look what the cat dragged in.

Geobits

We'll see soon enough how well the polls did this time around I guess.

DrMcMoylex

@Dennis Done. :)

mınxomaτ

I mean if they are trying to be biased in either way, they are not doing a great job.

Geobits

00:45

I live in a heavily Democratic district of a nearly-tied swing state, so it'll be interesting.

ETHproductions

Does anyone in here know enough about Jelly to help me figure out something?

Geobits

I know you can make it with most fruits or vegetables and a bunch of sugar and pectin.

I've done that once or twice, but I'm no expert.

ETHproductions

Jelly with a capital J, Mister Misinterpreter :P

Geobits

Yes, I agree that Jelly is important enough to get proper-noun treatment :P

ΛεγίωνΜάμμαλϠΟΗʹ

CMC: Find me a Unicode character that looks ~~mostly~~ the most like a superscript semicolon

ETHproductions

00:48

Does anyone in here, excluding Geobits, know enough about Jelly to help me figure out something?

Geobits

@ΛεγίωνΜάμμαλϠΟΗʹ Semicolon looks mostly like one.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@El'endiaStarman you might like this

Helka Homba

Is there a noncolon character? Like ; but both dots are commas?

ETHproductions

@ΛεγίωνΜάμμαλϠΟΗʹ ⁱ is close

Not close enough though, probably

ΛεγίωνΜάμμαλϠΟΗʹ

@ETHproductions lol, that's a superscript i

Eᴀsᴛᴇʀʟʏ Iʀᴋ

00:51

@HelkaHomba none that I can find here

ETHproductions

I know, but I can't find anything better

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@HelkaHomba i plead innocent

Geobits

o_o

Spit the bird out right now, little cat.

Doorknob

@HelkaHomba "Byzantine musical symbol ypokrisis" 𝀊 is sort of close.

ETHproductions

If there's a superscript Greek question mark, that would work

mınxomaτ

00:54

@Doorknob There should be an automatic crossword generator with unicode. The clues are the characters, and the words are their descriptions.

7

Call the game "White Boxes"

Which is both a fitting title and a pretty good pun. On demand, you can pull up random trivia about the language used.

I would totally play this.

ΛεγίωνΜάμμαλϠΟΗʹ

@xn--EsI-uxbb2g5e786v3ba2b0l I have found your true name

ETHproductions

@ΛεγίωνΜάμμαλϠΟΗʹ The closest I've found so far is ˸ (modifier letter raised colon)

quartata

@mınxomaτ That would be pretty easy to make except for picking which characters to use that will render more or less everywhere

mınxomaτ

There is a complete unicode fontset. Convert that to WOFF und load it on the site.

Geobits

World of Final Fantasy?

Maltysen

01:05

@mınxomaτ there's some weird rules to making crosswords right?

like 2/3 have to be white or something

and a few others

mınxomaτ

There's lots of edge cases with this idea anyway.

Maltysen

> The grid is diagonally symmetrical

(╯°□°）╯︵ ┻━┻

ETHproductions

Really? I thought it just had to be rotationally symmetrical

quartata

Wouldn't a full font be huge though

Dennis

@DrMcMoylex >.<

mınxomaτ

01:06

Sure.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Geobits a bit late now

mınxomaτ

The idea is completely infeasible. It would be way too hard, too. Assuming blank boxes for all characters. The clues would have to be more detailed than just the character.

miles

@xnor Great rewording for that second condition in the binary sequence question, it got much clearer

quartata

It's pretty easy to filter out bad characters with Python's unicodedata.category so this would actually be more feasible than you might think

And most of the Unicode character names are fairly consistent so with practice figuring it out might not be that bad

Q: Should we be flagging questions as duplicates?

I have seen a lot of questions flagged as duplicated and so blocked recently, some from established members and some from new members. In several cases these have not been exact duplicates but have had some (sometimes small) difference that does not make them a direct duplicate. While I am tota...

Maltysen

01:11

we can just steal this for the crossword generation: bryanhelmig.com/python-crossword-puzzle-generator

there are plenty of js crossword displayers

ETHproductions

I actually made a font for making crosswords a few years ago

When I was more into font design and less into code golf

Geobits

Maybe you should try golfing fonts?

ETHproductions

How would I do that? Smallest NxN pixel grid?

Geobits

All you really need to do is put a hole in one.

Helka Homba

@ETHproductions Ooh, are all the chars perfectly square? (If that's even possible?) Would be good for ascii-art/2d programming

Maltysen

01:16

@Geobits ._.

ETHproductions

@HelkaHomba Yep

Geobits

@Maltysen I almost want to apologize for that.

Helka Homba

@Geobits Can we push you down your stairs?

Geobits

Dunno. Can you?

ETHproductions

@Geobits It's been done.

Helka Homba

01:17

@Geobits Yes. Did. Done.

Geobits

@ETHproductions Oh geez. I just meant a hole in the 'one' glyph. That's terrible.

Helka Homba

@ETHproductions Except I'm not going to make an account just to download one file..

ETHproductions

Yeah, it sucks that you have to sign up to download a font :|

Maltysen

> from copy import copy as duplicate

that's horrible

Eᴀsᴛᴇʀʟʏ Iʀᴋ

holy

o_o

i have seen awful code

52 if statements in a row

for what day is it

Helka Homba

01:22

Deck of cards?

oh

ETHproductions

@EᴀsᴛᴇʀʟʏIʀᴋ 52... that's the tenth Fibonacci number minus the fourth!

Eᴀsᴛᴇʀʟʏ Iʀᴋ

okay then

@HelkaHomba *week is it but eh

Maltysen

@ETHproductions relevant xkcd: xkcd.com/587

Eᴀsᴛᴇʀʟʏ Iʀᴋ

nice

Geobits

Semi-related Puzzling answer with way too many upvotes

Helka Homba

01:26

@Maltysen You should make an elusive and valuable Python guide and call it The Maltese Python

Dennis

@ETHproductions Feel free to ping me in the Jelly room if you have a question. :)

El'endia Starman

@EᴀsᴛᴇʀʟʏIʀᴋ Oooh, neat.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yes

Maltysen

@mınxomaτ do crosswords have spaces?

mınxomaτ

Some do. But I've never seen a crossword from a ... serious source use spaces.

Maltysen

01:32

so I should just strip the spaces from the things

Eᴀsᴛᴇʀʟʏ Iʀᴋ

yes

mınxomaτ

I never did an English crossword though. So milage may vary.

Maltysen

cuz our words here will like "LOWER LEFT PENCIL"

so LOWERLEFTPENCIL is that how they normally do it?

mınxomaτ

"Can you pass me the pencil?" - "Which one?" - "LOWER LEFT PENCIL!"

ETHproductions

@Maltysen Yeah, and that's exactly 15 characters long, which is the typical size of a crossword (I think)

mınxomaτ

01:34

@Maltysen Probably a good idea. I thought about dashes, but I guess some unicode desc. do have dashes.

Helka Homba

@Maltysen They don't. (Unless very rarely.)

You mush the words together. They have blacked out in spaces though.

noɥʇʎPʎzɐɹC

how do you extract a rar? google isn't helping

Geobits

os?

noɥʇʎPʎzɐɹC

@Geobits mac os x, but any *nix one will work

Unix is pretty compatible.

Geobits

01:43

I just use unrar on ubuntu. It's in one of the default repositories. Dunno about osx

mınxomaτ

Or use 7z

noɥʇʎPʎzɐɹC

@mınxomaτ windows only

mınxomaτ

Lol, no it isn't

Geobits

Oh, I forgot about 7z :)

mınxomaτ

7z for OS X is called kekaosx.com

One might slowly arrive at the conclusion that you are somewhat incapable of using Google.

Geobits

01:45

Once installed (at least on ubuntu), unrar uses the same frontend as zip, gz, etc. So no new context menu entries.

noɥʇʎPʎzɐɹC

@mınxomaτ 7z first page @ google mentioned only exes, dlls, and windows links

mınxomaτ

7z on unix is command line only (by default)

@noɥʇʎPʎzɐɹC That's a crappy excuse.

Geobits

"osx rar" query similar

mınxomaτ

CµC: Golf google query that shows keka on page 1 (w/o using "keka")

noɥʇʎPʎzɐɹC

brew install 7z<tab> wait five secs for homebrew directory to be searched brew install p7zip

did it for me

@mınxomaτ interesting...

Geobits

01:49

@mınxomaτ 7zmac so far

noɥʇʎPʎzɐɹC

what does it stand for?

Geobits

Oh, "7z x" works too, but almost off the first page.

noɥʇʎPʎzɐɹC

@Geobits that's hard to beat...

How much can 3 bytes express?

...just three bytes, it turns out

Geobits

Yeah I couldn't think of anything to shrink that

noɥʇʎPʎzɐɹC

512 three most important queries, can keka really be one of them?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

01:55

@Geobits x 7z has it close to the top of the first page

noɥʇʎPʎzɐɹC

Information theoretically, I think it's impossible to keep golfing

Geobits

512?

noɥʇʎPʎzɐɹC

@Geobits 8**3 = entries expressible by three bytes

p7z x works, but it's longer

Geobits

Uh, one byte isn't eight values

ETHproductions

@noɥʇʎPʎzɐɹC Wouldn't it be 256**3?
