@totallyhuman PowerShell, 23 bytes Try it online!
 
(secretly hoping someone can find a arithmetic correlation)
 
... is there any arithmetic correlation?
 
@J.Sallé That's good too, but you can golf it to 14: 1 1 4 4 2⊃⍨5|⊢
 
3:09 PM
SOGL, 7 bytes: :Ω“L─.w
 
@dzaima Explain!
 
@Adám indeed! Still working out the new year's rust off my brain :p
 
Haskell, 19 bytes: Try it online!
@dzaima :O
 
@dzaima Oh :-(
 
3:12 PM
did you expect me to have made some cool math thing? There's a reason why I practically do only ASCII-art stuff :p
heh this works here too
 
@totallyhuman Dyalog APL, 13 bytes, pure arithmetic: 7|×⍨1+⌊2÷⍨5|⎕ (0 origin)
@totallyhuman @user202729 a(n) = mod((1+⌊mod(n,5)÷2⌋)²,7)
 
@Adám That × there is being used as a dyad to square the whole 1+⌊2÷⍨5|⎕ part, right?
To square the result of that, I mean*
 
@J.Sallé Yes, that's correct. Monadic ×⍨ is the same as 2*⍨.
 
I think PPCG should put out a survey, like SO did
 
Survey about what?
 
3:24 PM
@mbomb007 Yes, I thought that too.
@cairdcoinheringaahing Language preferences, ages, job situation, education, location, etc.
 
I think SO may have done it partially to help their job board thing, but I'm not sure. Some of the info seems like it's used to help tailor the job board to users' preferences or better design SO jobs to appeal to more developers, but I don't know exactly how they use the information.
 
Yeah there were some pretty sensitive information that (IMO) isn't useful to them in any way
 
@HyperNeutrino Yeah, one of my co-workers gave up 5 minutes in because all the first questions were so obviously tailored to improve SE Jobs. He's happy with his current job.
 
@HyperNeutrino Obviously, Joel is planning to take over the world by turning off SE until we pay the ransom :P
 
@Adám hah lol :P
@cairdcoinheringaahing quick! clone all of the source code and start a new instance!
also when adam pinged me i got confused because i'm also talking to my IRL friend Adam on google hangouts
so i'm like "how did he track me down, did he actually look at my SE profile or something"
 
3:29 PM
@HyperNeutrino But I have a ´ more than him!
 
@Adám that's when i stopped being confused :P
 
@cairdcoinheringaahing CMC: Download SE.

Q: Why Google Translate translate back not same as the first time translate?

zixuanI translate "How to use Web?" but translate back to English not the same as first time i translate this.

Looks like the question itself is translated by Google translate.
 
(HNQ)
 
3:30 PM
That's in HNQ ಠ_ಠ
 
the username looks chinese to me
wait HNQ? that has net score 2!!!1//1?1/one
 
@HyperNeutrino Agree.
 
and the one answer is accept+13
i don't
understand

@Mr.Xcoder Explain!
 
3:33 PM
@Adám Compression!
 
Number, to decimal, index.
Is it monadic?
 
It should be
 
@Mr.Xcoder 0/10. Translate my arithmetic formula.
 
If so, (_i)(D) should work.
(ịD)
 
@user202729 The use of the nilad links quick would make it the same length
 
3:34 PM
⁽)Ḃ -> 11442, D -> Decimal, ị@ -> Index with swapped arguments
 
No it doesn't. (?)
 
Alternatively, ị⁽)ḂD¤
@Adám This one? 7|×⍨1+⌊2÷⍨5|⎕
 
"This is obviously not optimized for speed, but it runs in about 7 seconds on my laptop." Is Python that slow?
 
No...
 
3:36 PM
@Mr.Xcoder Yes, or the equivalent math one: a(n) = mod((1+⌊mod(n,5)÷2⌋)²,7)
 
Yeah brb translating
 
%5:2‘²%7
 
This is where caird ninja's me

Anyone up for JHT?
 
3:40 PM
random question: can i still be pinged in JHT?
 
checks homework I should be free for about an hour
 
@HyperNeutrino Nope.
 
rip :(
 
Come train with us
 
Somebody should submit my formula to OEIS.
 
3:42 PM
Is it interesting?
 
@user202729 What, the formula?
 
3:54 PM
@Adám that somebody being you?
 
4:10 PM
@totallyhuman I doen't have an account.
 
I have an account, I'll try to submit it
 
> After investigating, Microsoft has determined that some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown
 
@Adám Submitted an edit.
 
@Mr.Xcoder Shouldn't it say n-1 ?
 
No, not necessarily 0/1 indexed I think
 
4:17 PM
@Mr.Xcoder ah, ok.
 
Wait I forgot to submit
Done.
 
I wonder if there is an arithmetic formula for every periodic sequence. I think there must be.
 
Polynomial interpolation.
 
:42177675 BASIC or APL or Microsoft Word macro language, not sure which.
 
@Poke So Microsoft got bogus documentation, made a software fix, and said software fix bricks the machine. Nice.
 
4:20 PM
Sorry, pressed wrong button.
 
Commodore BASIC for me.
 
@user202729 How is that going to work on an infinite periodic sequence?
 
Modulo period.
(hopefully it will work)
 
@user202729 OK, sure, with modulo period.
 
4:25 PM
@AdmBorkBork pretty much but I bet they still catch the flak
 
The polynomial will be of degree N-1, and the denominators will be 1~N-1. So they are invertible (hopefully) modulo N
 
@Poke Just like what happened with Vista. Microsoft said they were updating their driver model, updated their driver model, but vendors didn't update drivers so everything broke. Then Microsoft took the blame, waited a few years, and released Windows 7.
 
holy crap firefox quantum is noticeably faster
i'm super late but that's awesome
 
@totallyhuman faster than what?
 
chrome
it's not even placebo
 
4:33 PM
@totallyhuman I've switched too. Faster, less chrome (!), less memory bloat.
 
right, only thing stopping me is the fact that i use a chromebook ;-;
 
firefoxbook
 
@Adám same here. FFQ is by far better than Chrome
 
5:21 PM
likes chrome, doesn't understand browsers' obsession with removing it
 
Interesting neolang with some strong performance claims: github.com/felix-lang/felix
 
@Riker I made it to 13!
 
I'd switch to FF, but I don't want to go threw the process of carrying over my favorites and extensions and saved passwords and such
 
@Pavel Favourites and passwords are automatically carried over.
 
5:38 PM
@Solver yep!
welcome back
@totallyhuman ikr it's quite nice
 
I especially like that FFQ lets me put bookmarks on the same line as the address bar:
 
5:56 PM
@AdmBorkBork sad times
 
@Adám I tried and they weren't :/
 
@Adám I don't use my bookmarks enough but I can see how that's nice
@Pavel took me a bit too
just got to open up teh bookmarks window, then import from teh top menu
 
@Pavel I think you have to ask for it explicitly (which I like).
 
@totallyhuman RIP
 
@totallyhuman Which Chromebook?
 
6:09 PM
@Adám Didn't old versions of Firefox let you do that?
 
@Neil I think so, but I went from Chrome to FFQ.
 
although, not between the forward button and the address, I think
interestingly I submitted my comment after @Adám but before I received his comment so that it still showed up as an unread notification
 
@Neil Heh, I can even put the bookmarks between Fw and Bk.
 
6:23 PM
@Adám Acer r11
 
I've tried
not quite the same
 
@totallyhuman Even the Beta version?
 
 
1 hour later…
7:37 PM
Yay, the SourceForge redesign / rework is finally online: sourceforge.net/blog/introducing-the-new-sourceforge
 
Hm, I want to ask the clever fellows here about something we're planning for the next version of Dyalog APL, but it is a weighing of two concepts, both of which are foreign to the non-APL world…
 
@Adám Go with the second one
/thumbs up
 
@Poke Uh, but the whole problem is how to order them ;-)
CMP: If we compare two empty arrays to find which precedes which, what should be more significant, their shapes or their (prototypical) content?
E.g. if A is a 0×0 character matrix and B is a 0×1 numeric matrix, should A precede B because it has lesser shape, or should B precede A because* it is numeric vs B being character?
 
An array of arrays (or a matrix) seems "bigger" than just an array or vector.
 
@AdmBorkBork A and B are both matrices. The is CMP only regarding arrays of identical rank (number of dimensions).
 
7:51 PM
Oh, I misread.
I would say that A precedes B because it has lesser shape, though I can't give any reasoning for it.
 
lesser shape, assuming that you can check the shape
I'd expect 0x1 to be greater than 0x0
mainly because it has a 1 /shrug
 
@AdmBorkBork In other words, you're saying that shape is more significant that prototypical content.
 
Yeah, but like I said I can't give any reasoning for that. It's just a gut feel.
 
@AdmBorkBork Well, at least I'm not alone in having that feeling.
@Riker Well a 2×1 numeric matrix precedes a 1×1 character matrix, which seems to indicate that data type is more important than shape.
@Riker In APL, you can always get the shape of an array. It is essential to the language.
 
@mınxomaτ Wow, I haven't used SF in years. I didn't even know they were bought.
 
8:03 PM
@AdmBorkBork The new CEO/President was very transparent about this though: reddit.com/r/sysadmin/comments/4n3e1s/…
 
Why am I not surprised that Downgoat's highest voted answer is a more destructive JS version of rm -rf?
3
 
@Adám that's not appropriate imo >_>
 
@Riker Why not? 'a' 'b' comes before 'z', no? So if all numbers come before all characters, then 0 1 should come before 'a', no?

Stephen LeppikDo I have the same number of factors as the next number? code-golf factoring decision-problem number-theory This challenge is simple: for the input integer n≥2, determine whether n has the same number of factors as n+1.

Btw, is there a chat room dedicated to language design?
 
8:13 PM
@Adám I don't think so, but that's pretty on-topic for TNB all things considered.
 
@mınxomaτ Huh. Fascinating. Thanks for sharing.
 
@Pavel OK, thanks.
 
People working together on one language specifically might make a room for that one language.
 
@Adám yes
1 sec
 
@Adám is it an esoteric language?

8:15 PM
@totallyhuman Nope. Industrial strength production language.
 
there's one I'm pretty certain
hm, can't find it, probably frozen

@Riker Oh well, I'll just stay here. Tell me to shut up if it interferes with other on-topic discussions.
 
don't worry about it
feel free to keep talking in here @Adám
since that room is pretty dead
 
@Riker Yeah, there's always the downside to dedicated rooms for discussions that merit input from anyone, that there is less exposure there.
 
8:20 PM
nice edit lol
 
@Riker Wait, what‽ You edited the post without actually changing anything, causing the one-box to refresh?
 
I'm making a new language. What dhould it be named?
 
@WheatWizard What's the basic premise?
 
@mınxomaτ The page for downloadin prebuilt binaries seems to be down :(
 
@WheatWizard Grain.
 
8:23 PM
@cairdcoinheringaahing You don't need to know.
 
I always name my languages off the basic premise
 
Does anyone get anything at http://felix-lang.org/$/usr/local/lib/felix/tarballs other than just a line that says /usr/local/lib/felix/tarballs
 
Grain Mage.
 
@AdmBorkBork or einkorn enchanter
 
@cairdcoinheringaahing It's better for this language if the name is not related to the premise
 
8:24 PM
Goddamn dollarsigns in urls breaking markdown
 
@WheatWizard "Name is Unrelated"
 
I used to do that, but now I have Funky
 
@WheatWizard Now I'm intrigued. OK, so not related to the naming, what is the basic premise?
 
@WheatWizard Now I'm intrigued
Goddamn ninja ಠ_ಠ
 
@cairdcoinheringaahing Good name
 
8:26 PM
weird flag
 
ლ(ಠ益ಠლ)
 
oh great argument flagging
 
@WheatWizard How about just "Intrigue" as the name?
 
@Adám Each program is a function tree where the tree is as balanced as possible
 
i would've said functree but guess that's forbidden (and it's not very creative anyways)
 
8:28 PM
@WheatWizard Uh, uh, I have a name, but now I'm not allowed to suggest it, as it relates to the basic premise… :-(
 
@Adám yep
 
@cairdcoinheringaahing ...wait what
 
@Adám Eh go ahead, I've allready gotten quite a few good suggestions.
 
works with question oneboxes too
@WheatWizard Graindalf
 
8:29 PM
@cairdcoinheringaahing facepalm
 
@WheatWizard "Forest" or maybe "Gump".
 
@WheatWizard Wheat-Flak
 
ಠ_ಠ It tries to parse 0001, which oututs this (explaining the first two 0), but I have no clue about the [1, 1] part
 
I assume you’re implementing it in Haskell?
 
@Mr.Xcoder no graindalf is better
 
8:32 PM
@Mr.Xcoder yes
 
@Riker Subjective
 
@Mr.Xcoder -1 Unoriginal
 
@totallyhuman Yeah, but the tells it to eval each, so it should be 0011
 
Thanks guys for all the names. We are planning on randomly selecting the name from all of your suggestions plus a few of our own.
 
8:34 PM
"we"?
 
Myself and 0'
 
ಠ_ಠ Jelly sucks at strings
@Blue Nice profile picture
 
Thanks :D
My friend drew it for me as a gift. I've got a full reference with it
 
8:49 PM
:O You can make replies in multiline messages
 
@Pavel shift-enter
 
goes to Sandbox
 
@Blue Well I know how to make multiline messages, I just didn't think it would allow replies.

is the background a forest? or just something cool the matches the wolf
@WheatWizard weight graindalf 3x /s
@Pavel yes
 
8:52 PM
I'm guessing it's probably a forest but it was just a minute mini thing
 
Ok we have selected a name it is "Jelly, 3 bytes"
6
 
@Blue it's quite nice of a background
 
@WheatWizard ಠ_ಠ
 
For real ಠ_ಠ
 
@WheatWizard that's perfect
 
8:55 PM
So your submissions will be like "Jelly, 3 bytes, 3 bytes"
 
for best results I want to say "Jelly, 1 Byte-characters" would be slightly better
but that sounds like a cool name
 
@Riker It is. The artist I used does backgrounds really well
 
@WheatWizard Are you applying the same process that you select your profile pictures to your language name choosing?
7
 
@Blue All those are amazing

I suspect that @WheatWizard Has slowly been taking the brain-cells that were previously dedicated to "Spelling" and "Deciding what avatars to use", and dedicating them to Brain-flak golfing skills
 
8:57 PM
So, mash the (){}[]<> keys and use whatever ASCII comes out as the program name?
 
Thanks :3
I've got a couple more but I'm not really up for sharing them here

I'm writing a program to compute e^3 to 1000 digits
 
8:59 PM
Using Jelly?
 
Then use 05ab1e :P
 
there's a twist: it's e^3 defined using the taylor expansion, in 3-adic integers
 
> žt | Pop a, push e to a digits (max. 10000)
 
it turns out that e^p converges in p-adic integer, as long as p>2
