@Adnan Oh, I guess it isn't in the formula section, it's the Pari reference implementation. (Which, since it gives a closed-form solution, should probably be written out in formula section.)
 
(but wait...that's trivial :P)
 
@AlexA. Awww :(
 
@AlexA. How do we know this formula/implementation is actually correct?
(It looks like they were even having a hard time coming up with the value for n=12 very recently)
 
Hey guys, something interesting to look at: Pascal's triangle, but instead of just doing x+y for each pair, do 1/(x+y).
 
@quintopia Running on a bunch of test cases
 
7:03 PM
Why not x^y.
 
@flawr That could be interesting too.
But I've noticed an interesting pattern already with the fractional version.
 
@El'endiaStarman keeping everything as rationals?
 
Change the input to generate more rows, change the + to define what operator to use.
 
@MartinBüttner That would be best to keep up the precision, but I'm also looking at the decimal representation.
 
@AlexA. I said "know", not "intuit"
 
7:10 PM
Here's the first 8 rows of ^:
 
@ETHproductions "change the +".......I don't know Japt... :P
 
1
1,1
1,0,1
1,1,1,1
1,0,0,0,1
1,1,0,0,1,1
1,0,1,0,1,0,1
1,1,1,1,1,1,1,1
 
But besides, I'm investigating in Python.
And I think there's a diagonal that converges to sqrt(2).
 
@El'endiaStarman That's fine ;) it's a basic version that you can use any normal operator: + - * ^ & | etc.
 
How would one do 1/(x+y), then?
 
7:12 PM
@ETHproductions I think XOR just gives the Sierpinski triangle.
 
Yeah, it does
I'll investigate other options...
None of the other operators are interesting at all :P
 
did you try 1/(xy)
wait
nvm :P
did you try...1/(1+xy)?
 
@El'endiaStarman it also seems that differences along each row keep alternating.
 
@quintopia Not yet, apparently there's a big bug that makes most options impossible atm :P
Found a workaround now
 
here's the first 25 rows as decimals: pastebin.com/KLEfUZtA
(of 1(x+y))
 
7:16 PM
Yep, looks like it converges to sqrt(.5) in the center.
 
And here is the first 15 as rationals: pastebin.com/T5Tbkbxk
 
2/(x+y) stays at 1 eternally
But 3/(x+y) converges to... I can't tell...
 
@MartinBüttner eeeeenteresting
 
@ETHproductions It.....doesn't, actually. Which is really weird. It does seem to converge to sqrt(0.5) around 1/5th of the way across (so, positions 20 and 80 out of row 100).
That bump in the middle bewilders me.
 
7:19 PM
@El'endiaStarman wow such matplotlib
 
The font and the fact that it looks nice gives it away.
 
hahaha, yeah :P
Row 1000:
 
That's... weird.
 
@MartinBüttner it's so weird how the rows wobble in magnitude, unlike the original, which always increases toward the center
that one column has fibonacci ratios in it (so obviously converges to phi)
 
7:23 PM
Those are the values of the center.
 
Interesting.
 
@quintopia the second one you mean?
 
What about 4/(x+y)?
 
X-axis is row number, if that wasn't clear.
 
@El'endiaStarman are you sure the bump in the centre isn't numerical inaccuracy?
 
7:24 PM
@MartinBüttner It could be, I guess.
 
using rationals, for N=30 the centre is almost flat but dips down a little bit.
I can't go much higher than that, because the rationals blow up fast
 
4/(x+y) seems to converge to sqrt(2) somewhere between 1/8 and 3/8 from each end, I think...
But I don't see where it's converging to in the center.
 
Okay, I just confirmed this: for even n (in my program), the center bulges up. For odd n, it dips down.
Which makes sense, given the latest plot I posted.
 
true
I think N=30 in my program might be row of width 31 actually
 
So you're probably right that it eventually flattens out.
 
7:27 PM
@MartinBüttner yeah. though i guess that should have been obvious given the definition :P
 
Geez, someone coming in for the first time might think this is the Mathematic(a|s) chat room. :P
 
likewise if you always put 2's, you should converge to 1/root(2)... yeah?
 
Hello (from the other side)
 
@ETHproductions It's not? wanders away
 
7:29 PM
@ETHproductions better than what they might think with the stuff that usually fills the transcript recently...
 
nobody likes Adele...
 
...and yet she has several billion views on YouTube. :P
 
@TanMath That's not true; quite a lot of people like Adele. Her music is very popular.
 
That red dashed line is 1/sqrt(2).
The bulge/dip in the middle almost certainly converges to that.
 
7:30 PM
I mean, over here...
 
I don't mind Adele.
 
but nobody found my pun funny... oh well
hello anyway!
 
@El'endiaStarman Gabriels trumpet ran over by a roller compactor?
2
Or filled with blue paint?=P
 
haha :P
 
I like Adele's music.
 
7:33 PM
I don't listen to any pop culture music.
 
@TanMath who would have guessed?
 
nobody!
 
@El'endiaStarman Only post-hardcore?
 
That was insane.
The onion knight hat reason i mean.
 
@El'endiaStarman Me neither, at least not actively, but still find some main stream songs I like every now and then. E.g. Adeles Hello=)
 
7:34 PM
Nobody could ever ever guess that.
 
(Or is "I neither"?)
 
exactly...
 
@El'endiaStarman It certainly does, as 1/root(2) is the unique positive solution to a=1/(a+a)
 
@AlexA. Post-hardcore = softshell?
5
 
But congrats @quartata for being the first one to get it!
 
7:34 PM
The fact that it arises from anonymous votes ovbiously means nobody could guess it

Q: The Rien Number

Cᴏɴᴏʀ O'BʀɪᴇɴThe Champernowne constant is a number that is constructed by concatenating the first n numbers, with n tending to infinity. It looks something like this: 0.123456789101112131415161718192021222324252627282930... Now, I will describe to you the Rien number. It can be thought of as a minimization...

 
What if we tried this triangle with trigonometric functions?
 
¯\_(ツ)_/¯
 
@AlexA. I enter the chat, and see this. What even

@AlexA. Omg, this stuff is great, instantly reminded me of Inter Arma!
 
this is also the best way to quote the person above you
if someone else posts...

You're Gonna Go Far, Kid, by The Offspring is fun to listen to.
 
@NewMainPosts Thank you @NewMainPosts.
 
7:40 PM
@orlp It's fun to highlight this.
 
@RikerW Thank you @RikerW for thanking the @NewMainPosts that has my @NewPost
 
@CᴏɴᴏʀO'Bʀɪᴇɴ You are welcome.
Everybody join me in thanks!!!!
 
this is one character: ∰
 
@flawr here is some more.
 
Yeah, the math portion of Unicode is weird.
 
7:41 PM

@orlp #triplelineintegral
 
@orlp Yup, the circular triple integral.
...semi-ninja'd?
 
 
Ninja'd, but mine was modern because it has a hashtag
 
ninjad
 
7:42 PM
@orlp Signature of my physician?
 
Hey, I just ninjaed ninjaed.
:P
 
I was about to say that :P so I was ninja ninja ninja'd
 
@flawr Btw in the "here's some more" thing I said earlier, each word is a separate link
 
@AlexA. I know, I'm listening to all of them simultaneously=)
 
One of the songs has a very NSFW name
 
7:42 PM
@ETHproductions I'm gonna go have breakfast now, but I'll investigate this when I get back.
 
@El'endiaStarman Isn't it like 2pm there? :P
 
@ETHproductions ಠ_ಠ because I can't test your solution in IE.
 
2:43. So what? :P
 
So this comment popped up in some python code my friend sent me:
#This command pops the list item
 
it's only time until this becomes a unicode symbol
 
7:44 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ Sorry, the Japt interpreter is kinda buggy atm. I'll fix it later.
 
@orlp Who is this
 
@RikerW :O I DIDN'T KNOW THAT
 
The problem was instead of a hash, he used a sharp sign.
 
I got up 12:30 or something, wrote down my idea on the whiteboard (including several rows of the triangle), took a shower, then came down here and did some coding to investigate.
 
@AlexA. the internationally recognized symbol of sarcasm, Kappa
 
7:44 PM
@ETHproductions Not a problem ;) Don't worry about it, I'm guilty too.
IE is weird.

@AlexA. Well accidentally, when I opened them all in new tabs. Did sound great though.
 
@ETHproductions I'm on my school tablet. Thus, I can only use IE :P

@CᴏɴᴏʀO'Bʀɪᴇɴ Bummer :( Well, try it when you're at a computer then
 
@orlp Where?
 
@ETHproductions I will! I trust that it works, though. ^_^
 
@RikerW everywhere
 
um...
 
7:46 PM
Upvotes all over his body
 
did anybody notice the meta post?
 
I notice spelling errors, not meta posts.
 
Anyone here using mono? I could use some halp
 
blah
 
Sorry, wrong thingy.
I don't check meta that often.
 
7:49 PM
@mınxomaτ I thought that was a question asking if any of us had mono :P
 
nobody cares about my challenge??

UPVOTE MY POST!!! :(
(I am joking obviously)
(but don't downvote!)
 
7:52 PM
So you want us to downvote it?

no!
 
WHAT DO YOU WANT THEN??
 
DOWNVOTES!
 
IDK!!!

We whould open a meta thread for collecting deep quotations from the nineteenth byte.
 
SOMEBODY NOTICE MY POST!!
 
WE EFFING DID!
 
AND SO NOBODY ELSE CAN SAY ANYTHING?? NOBODY ELSE LIKES MY CHALLENGE? WHY AM I WRITING IN CAPS LOCK??
 
BUT YOU DO NOT THROW A CAKE IN SOMEONES FACE AND EXPECT THEM TO LIKE IT. "HERE LIKE IT GODDARNIT, LIKE THAT EFFING CAKE, I MADE IT FOR YOU AND IT IS IN YOUR FACE NOW SO BETTER LIKE IT I DOUBLE DARE YOU"
 
WE LIKE TALKING IN CAPS TO SCARE ANYONE NEW WHO COMES IN THIS ROOM

@TanMath I hate it.
 
A ^^^^^^ cake.

Q: The ever-shrinking program

MuEtaWrite a program that prints the number of characters (including or excluding new lines, up to you) in your source code. Then, remove any one character from the source code and print the (reduced by one) new number of characters in the source code. Keep doing this for as long as you want. The cool...

 
NOW DOWNVOTE!
heheh XD
 
@TanMath "IF YOU HATE IT"
 
8:00 PM
@TanMath Lol, perfect timing of @NewMainPosts
 
What is even going on in here
I step away for 2 minutes...
 
Carrot cakes.
 
@mınxomaτ and somebody already downvoted it!
 
> I'M SHOUTING AT YOU BECAUSE IT'S CHEAPER! (source)
 
@AlexA. Do you like carrot cakes?
 
8:01 PM
@TimmyD OH OKAY
 
Not really
 
@AlexA. What cake do you like then?
@AlexA. Do you even like cake?
 
Hmmmmmmmm
Sometimes
Not very often
I don't really like frosting
It's too sweet
 
he likes this cake -> 💩
 
Frosting is good in moderation.
 
8:02 PM
translate: Frosting
Does not work.
 
@TanMath Crap?
 
@CᴏɴᴏʀO'Bʀɪᴇɴ yes, except smiling!
@mınxomaτ now it is closed!
 
That proves that IE is a cold and heartless abomination.
 
@CᴏɴᴏʀO'Bʀɪᴇɴ it is not smiling??
@CᴏɴᴏʀO'Bʀɪᴇɴ truth be told, it is showing the same on my desktop chrome
 
@TanMath Yeah. Chrome is likewise.
 
8:05 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ chrome isn't that bad, ok??
 
@TanMath reloads shotgun
 
Anyone used to play that?
 
@flawr wait, what???
 
@flawr Those faces will haunt me in my dreams now. Thank you.

8:07 PM
@flawr Those graphics tho
 
@CᴏɴᴏʀO'Bʀɪᴇɴ Tan shot first (get the joke?)
 
@AlexA. (or other mods) - is it possible to add a blurb on the closure paragraph directing users to the Sandbox instead of (or in addition to) the How to Ask page?
> Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question.
 
@AlexA. They were not that bad for the time then.
Omg. 13 years ago 0.o
I feel old.
 
@TimmyD Since that's a standard close reason, I don't believe so.
 
@TanMath sorta ;)
 
8:09 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ play of words I guess...
 
Dang.
 
@TanMath oh :D
 
but it seems my joke isn't funny
 
Can there be a "New Bounties" chatbot?

^
 
8:10 PM
@ThomasKwa Interesting. I like this idea.
 
@ThomasKwa How about "New Mars" or "New Snickers"?
Or "New Milkyway"?
 
I think that Thomas wasn't referring to candy. :P
 
Oh =(
 
"New new"
 
> Old is the new new.
 
8:12 PM
so "Old"?
 
Too old.
 
Can there be a "New Chatbot" chatbot?
 
@flawr TIL "Bounty" is a candy bar
 
^
 
Shame that it's not here in the US ... I personally don't care for Hershey chocolate, which is what Mounds is
 
8:13 PM
@TimmyD Don't you know Celebrations?
TIL That this is from germany....
Ok.
I thought that was a 'murican thing.
But judging by the size, it cannot possibly be american.
 
Too small? :P
 
Yes.
 
can there be a "upvote this post" chatbot?
 
Nah, those sizes are sold all the time around Halloween
 
8:15 PM
come on!!
 
@TanMath Do you want to be replaced by a bot?
 
how about "upvote this meta post? chatbot
 
@flawr we do the answering, you see?
 
8:15 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ Big blue ladies?
 
@CᴏɴᴏʀO'Bʀɪᴇɴ bb
 
BBKING!!!!
 
@flawr and the bot isn't even doing the upvoting, it is commanding PPCG members to do the upvoting!!
 
Wow, candy bars are confusing.
> The British and Canadian Mars bars are very similar to the United States Milky Way bar, which Mars, Inc. produced (not to be confused with the European version of Milky Way, which is similar to the United States' 3 Musketeers).
 
carrot cake!
anyway I got nothing out of this UPPERCASE session and my post will be in the sandbox for the next 5 years...goodbye guys!
 
8:21 PM
@CᴏɴᴏʀO'Bʀɪᴇɴ explanation added to the Retina answer
 
8:35 PM
lol Living in the Future was the rarest hat?
I got that one really easily.
Anyways, Onion Knight was crazy. No way anyone would have guessed that
 
@quartata You're rare to.
 
It was a catalog answer so
Also I see @Zizouz212 got an honorable mention in that blog post
 
!
Featured questions. Cool.
You should probably give it a better name than "Feeds 1788" though :P
 
I gave it the name New Bounties
 
8:46 PM
Patience.
 
Looks like we need another @PhiNotPi graphic for its user icon.
 
@AlexA. Oops, I just called it New Featured Questions.
 
I'd say that's kind of a misnomer unless you call it Newly Featured Questions.
New, at least to me, implies that it was newly posted, not newly featured.
¯\_(ツ)_/¯ I'm just being pedantic
 
Newly it is.
 
+1
 
8:49 PM
@AlexA. Sure thing.
 
I gave it an interim icon.
It's pretty legit.
 
Stop ninja-ing me. :P
Ugh.
 
Ugh? It's the One True Icon™.
 
Can confirm: is icon.
 
@Dennis Gnuly?
 
8:53 PM
 
lol
 
^ outdated
 
nooooo
@Dennis You should make this look shitty and pixelated in keeping with the other feeds icons
 
hahaha
We need a featured question to test it.
 
8:57 PM
I'll start a bounty
 
Are you kidding me?
