help question: how do I get all pairs between two lists in 05AB1E?
Oops mapcommand over peekall is broken :/
what that means: you can't iterate over PeekAll to modify it rn :/
oh right cartesian product that's what it's called
huh SOGLs compression alone is much better than bubblegum
Anonymous
13:04
Does it use Huffman coding?
@Dennis SOGL beats bubblegum. How do you feel about it?
@Mego it just takes the characters used and makes them all equally costy
Anonymous
Also DEFLATE might give better performance in Bubblegum - I only tried zlib
@Mego almost certainly
Although damnit it's still longer than SOGL :|
13:06
what compression does charcoal use?
I'm guessing brotli here, maybe LZMA
Actually
@ASCII-only oh so it just picks the best one?
@dzaima Yeah
@NieDzejkob That won't summon him; it only works for Jelly :P
@HyperNeutrino although you'd still save by using reflection
13:08
Hang on >_> forgot to make the golfer remove trailing ending string delimiters
but he created bubblegum too...
oh ok :P
@NieDzejkob yeah I know :P
but Jelly is the best language he has in terms of golfing (in my opinion) so as long as Jelly isn't beaten it's fine :P
@EriktheOutgolfer You only have one dimension wait it should work, maybe I just haven't added to grammar yet
@HyperNeutrino is currently the best language
Actually it probably will be for a while
@ASCII-only you know his was 17 bytes right?
13:10
@ASCII-only but UR is already recognized by charcoal
@Neil :| charcoal's compression is too good (also 16 bytes because the last character isn't needed)
@EriktheOutgolfer Yes but I don't think I have an overload taking one less argument yet
@ASCII-only except that's not the case...maybe the arrow bothers with it?
@EriktheOutgolfer why not just remove the ?
you think it's causing the issue?
oh wait that's what causes the issue
@EriktheOutgolfer :| oh yeah Neil just pointed out the issue, since you used a potentially binary operator it interprets the body as a lambda
And then fails since lambda can't be used in most places atm
13:21
Tetranacci numbers lol
I wonder how many there are on OEIS
@Hyper Heh a tiny edit issue :)
ಠ_ಠ Tetranacci is soo easy
I have a feeling that my first gold badge will be the one, if I ever get it...
@Mr.Xcoder well you can't blame me for trying to make the sequences easy :P
@HyperNeutrino Heh I now have 4
13:26
@Mr.Xcoder :o nice :P
(In fact, you have about 4-6 badges more than me in each type, which is like nothing for bronze, a bit significant for silver, and really huge difference for gold :P)
@HyperNeutrino Do people get other gold tag badges before O_o
apparently people often do? not sure
wait I didn't know you had gold @Mr.Xcoder nice
@ASCII-only No, normal badges
@Mr.Xcoder Oh :| you don't have gold badges yet
oh cool you got it this past saturday congrats :D
@ASCII-only no he has 4, I have none
13:28
@ASCII-only ಠ__ಠ
In fact, as caird pointed out, I'm the highest reputation user without any gold badges :P
79/100 for fanatic yay
No idea now though, maybe mobile app
(I would have fanatic if they didn't delete my account when I was at 97/100 ಠ_ಠ)

user image
Yup
I have 200 score left for and about 40 questions over the requirement
13:29
@HyperNeutrino Btw I have the tag badge
Not sure how
If the OEIS challenge were code-golf I might have a much higher score lol
@Mr.Xcoder which one?
I think I will solve Tetranacci numbers in Swift :-)
Hope I don't get ninja'd
@HyperNeutrino BTW nice work on that crazy sequence :-)
^ Thanks :)
CMC: Given a String K, palindromize it using the following rules. If K is palindrome, output it as-is. Else, output K[:-1] + K[::-1] (every character of K until the last one + K reversed.

@HyperNeutrino Nope.
(not quite but that will be useful)
Jelly, 6 bytes: ¹ŒḄŒḂ?
@Mr.Xcoder SOGL, 3 bytes if ρ - is palindrome was implemented. Implementing it now
@HyperNeutrino why the identity?
13:39
Because ? requires it
<if><else><condition>?
ಠ_ಠ Jelly
yup default links should be a thing
(todo: make enlist do that to win :P)
@HyperNeutrino wait pls tell me enlist is not tacit
13:41
@dzaima wait what it's implemented? it just doesn't work..?
oh. I thought I implemented StringBuilder in the SOGLs JS version?
@Mr.Xcoder why sad-face
@HyperNeutrino Another language I am going to have trouble learning...
lol
it's very similar to jelly

@dzaima that works offline :p
13:44
Yeah well since you already know Jelly, it won't be as hard to learn (logic)
ಠ_ಠ you already know Jelly - You cannot simply know Jelly...
Why does it not calculate A76 properly? I'm starting to think that the OEIS entry is wrong
OK, some stuff can be negative
nevermind
@Mr.Xcoder wat
@EriktheOutgolfer What is unclear?
13:47
why it isn't just ŒḄ in jelly?
@EriktheOutgolfer because that bounces palindromes as well
@EriktheOutgolfer Because you have to handle palindromes
oh
then 6 bytes...oh wait I was going to write hyper's lol
NOOOO.... Ninja'd
oh... next page of answers... great
13:50
brachylog, 8 bytes: .↔|⟨kc↔⟩
@Mr.Xcoder whoops forgot about that rule lol
(maybe that's better for the challenge because the next one would have been yet another graph challenge lol)
> Number of even sequences with period 2n (bisection of A000011).
Does this one seem better to you, I don't think so
Yes it actually does.
@HyperNeutrino How is this one... easier?
because graphs are much less efficient to work with
13:57
@NieDzejkob Bubblegum was never meant to be competitive.
:o the summoning worked!
(:P)
@Mego zlib is DEFLATE with a 2-byte header and a 4-byte footer.
@Dennis Sorry for bothering you, but as of now, does Jelly lack anything M has?
A symbolic datatype.
oh ok...
I was about to get a heart attack... WTH Stack exchange...
Also I take back what I said; I don't understand the next sequence.
... due to caching
@Mr.Xcoder images blocked on my school wifi; pasteboard?
@HyperNeutrino Pasteboard.

cool thanks
owow :o :P
I wish that happened for real...
that would be awesome :P
@Mr.Xcoder It can
I have never received a bounty and though I just got one
Multiple sites, multiple days, or an answer was accepted

(or a bounty)
also the next time I go onto SO and ninja newbie questions, I should leave my achievements button and let it stack up for a while like cuz last time I did that I got a total of +348 reputation in one day :P
@HyperNeutrino :O what tag on SO?
mostly Python
Oh so that kind of questions... Write a list comprehension for me?
essentially "why doesn't calling a function work when I don't put brackets around it?" answer: it isn't Ruby
Damn it, caching. Got a +120 (not nearly as impressive but still)
@HyperNeutrino Nor Charcoal nor VSL
14:08
:P
Wait VSL lets you call functions without placing brackets?
VSL doesn't actually exist yet, but pretty much, yes
@Mr.Xcoder I think you can post your swift answer now
@ASCII-only ah ok
@HyperNeutrino No I can't...
Still not an hour yet?
@HyperNeutrino No, I just don't know the next sequence
14:09
@HyperNeutrino kinda sorta
wait nvm
i thought you deleted because of timing
but actually it was cuz ninja >_>_>_>

CMC: Given a number, multiply it by itself palindromized (even if it is palindrome, palindromize it)
Yes, input can be taken as a String.
124 -> 1540204

5 bytes in Jelly (for me).
palindromized as in lambda x: x[:-1] + x[::-1]?
@Mr.Xcoder 05AB1E, 2 bytes: û*
@HyperNeutrino yes.
@Emigna of course. Somewhat similar to my most recent 05AB1E answer on Main :-)
Jelly, 5 bytes: DŒḄḌ×
@HyperNeutrino I had ŒḄV×V and input as a String.
14:33
Ah okay, I see.
@Hyper up for a bit of JHT (not much)?
Sorry, not now. Doing history stuff
ಠ_ಠ History again.... /s
Did you notice that Bill Steihn has stopped posting stuff on Aug 30?
well history is first period, and then second period is a spare, great for doing history homework that was assigned at the end of class
I have to record myself reading stuff from a paper as history homework
14:38
>_>
how is that even useful >_>
@HyperNeutrino Then I must incorporate it into a 15 minute video... Regarding a historical building in the city....
And I must also record the video, get some music and take photographs
The most stupid HW I have ever seen
wtf that sounds stupid and boring
I totally agree
@HyperNeutrino It is very stupid and very boring, that is exactly why I hate history
yeah my teacher somehow makes class interesting but homework is still boring af
14:42
My teacher is the most boring teacher ever... And she's rather annoying
Don't say a teacher is most boring in the world until you meet mine
I hate history because of that and because it's practically just "memorize this"
@NieDzejkob Can't get worse. She's also very bad when it comes to history!!!
@NieDzejkob True.
Have either of you seen the Extra History videos on Youtube? (Channel is Extra Credits.)
@El'endiaStarman yes, but I do find that uninteresting nonetheless.
14:45
(lol the library is like the loudest place in the school and it's annoying because there are people speaking loudly in both english and mandarin which distracts me terribly)
(it's almost funny hearing the person next to me complain about stuff and being dumb lol)
Does anyone here watch Kurzgesagt (In a Nutshell) on YT?

You get used to it.
@Dennis I haven't so far...
Nor did I.
@Mr.Xcoder yes :D

I love that channel
this looks quite awkward with gradscript

@HyperNeutrino revert what
wtf is the new topbar?
@Mithrandir they gave mods the new bar early right? or something

Guinea pigs.
I've grown to like it. They actually improved the topbar UI a bit within the first week or so of its rollout for mods.
14:52
@Dennis Huh?
The only thing that still bothers me is the new site switcher.
@Mr.Xcoder SE decided to make all mods guinea pigs beta testers on the sites they moderate.
@Dennis *canaries
Oh ok... But you don't have any word to say against new features either right?
No, but we brought up a few issues. Some of them were fixed before today.

they're screwing around with our design...
yet they still don't give us a design...

Eww, just saw the new top bar. How do I get rid of it?
I guess I'm in the minority cause I don't think it's that bad >_>

Ugh, just turned the userscript off by accident and saw how ugly the site is without it. Thank you Downgoat!

In number theory, the Kronecker symbol, written as ( a n ) {\displaystyle \left({\frac {a}{n}}\right)} or ( a | n ) {\displaystyle (a|n)} , is a generalization of the Jacobi symbol to all integers n {\displaystyle n} .

Technically there's nothing in the definition of the Jacobi symbol that requires a to be positive, but the Kronecker symbol is the generalization.

@HyperNeutrino That's a finite sequence though

At least, finite in the sense that nobody has computed past 12
I smell hardcoding :P
Anonymous
Oh wait they're not finite
it's been computed up to 184...
Anonymous
16:27
For A411, you need to compute the L_{-6} Dirichlet L-series. Thankfully, they can be expressed in terms of Kronecker symbols: L_k(n) = sum(n=[1..inf]){(k/n)*n**(-s)} (where (k/n) is the Kronecker symbol).
Anonymous
So L_{-6}(n) = sum(n=[1..inf]){(6/n)*n**(-s)}
this sequence was done already but for a different number than 6
Anonymous
Oh? Then it should be easy
I think it was d(n,2) last time and d(6,n) this time which makes it more significantly different.

@DJMcMayhem I can't stand IPS. Every question that makes it to HNQ is basically "I don't like this person - how do I not talk to them?" or "I feel offended about something - how do I communicate that?"
@DJMcMayhem 7
@Mego Yeah, I agree. The idea is fine, but it suffers from the problem PPCG has (too many answers in general) because everything there is very opinion based
Anonymous
The answer to every IPS question is "have a mature conversation with the other person/people". The whole site can be closed as a dupe.

Also the fact that SE didn't give the community a say in whether or not they wanted it
