I think the operator is always associative in a group
 
Right. It's commutativity that isn't implied .____.
 
The term abelian, (having just looked it up) means that the operator is commutative as well
 
rip my lack of math knowledge .___. I was just studying groups not too long ago
 
Rip all my jokes
 
well that was stupid
I just did sudo delgroup sudo to see what would happen
and now I can't undo that because I can't run sudo things anymore .___.
well shit
 
12:04 AM
I think generally, if you're trying to "see what will happen" with the command line, it's probably going to be bad
 
su; addgroup sudo; addgroup alex_liao sudo didn't work either
 
Can you use su? (I have no idea)
 
Oh nvm
 
I think restarting might fix this...
hopefully ><
 
12:06 AM
I guess that's why you should remember how groups work :P
 
lol yes
that was actually a good joke for once
hey wow good jokes on SE? what? /s
 
ikr
 
yay restarting worked

@Dennis I mean it is 1k XD not even 1%
Now if you fix that by putting 500 rep bounties of every question I answer and giving it to me I would be just fine
 
Would still put me in second place. :P
 
Oh good point
 
12:32 AM
And the delete button is free.
 
I mean it took me almost a month to get my most recent 1k rep :P
 
Well lets be honest if you just removed my account without legit reasons in the end I would be back and you would be in a bit of trouble
@HyperNeutrino It takes me a while
I am lazy and tooo many hard challenges
 
lol same
that's why I make the hard challenges
 
I try then I lose my rep
 
(not the harder ones but some)
wait how do you lose rep

I've just accidentally achieved being able to type a single r for chrome to autocomplete to ruby.tryitonline.net
I don't even use ruby
I just golf in it occasionally
 
lol
what does c autocomplete to?
for you
 
12:41 AM
And it's done that since at least as long ago as November.
I joined the site in late september.
 
ok query by terms is done
might as well bump to v1.0
also i totally don't know what i'm doing
 
c autocompletes to chat ;_;
I've been using TNB more than PPCG.SE?
that's why I haven't been gaining rep as quickly ;_;
and co autocompletes to the meta site... I think this isn't simply by activity. :P
 
i should look up what is good python practise for modules
 
hey has anyone seen digital trauma around here recently

> Spaghetti code: multiple pages of nested if clauses and for loops with a lot of copy-pasted procedural code and no proper segmentation are known as spaghetti code. Python’s meaningful indentation (one of its most controversial features) make it very hard to maintain this kind of code. So the good news is that you might not see too much of it.
Ravioli code is more likely in Python: it consists of hundreds of similar little pieces of logic, often classes or objects, without proper structure. If you never can remember if you have to use FurnitureTable, AssetTable or Table, or even TableNew f
 
Guys I need help installing Ruby
   1 - MSYS2 base installation
   2 - MSYS2 system update
   3 - MSYS2 and MINGW development toolchain
What does all that mean and which one do I pick
 
I need a bit of help: I'm on Linux and I just created a new account and I'm trying to play Minecraft (don't ask why that's the first thing I'm doing :P), but Ctrl+Space is a shortcut to do something (I don't know what), which prevents me from playing. What does that shortcut do, and where can I disable it? For reference, uname -a gives Linux Alex-Acer-Aspire-E15 3.19.0-32-generic #37~14.04.1-Ubuntu SMP Thu Oct 22 09:41:40 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux.
 
@HyperNeutrino Switch keyboard language
 
oh
how do I disable it
 
xmodmap?
or something liek that iirc
 
12:57 AM
IDK, wherever the shortcuts are on Ubuntu?
@HyperNeutrino You could have just said you're on Ubuntu btw, that gives as much useful information as the uname output.
 
oh ok
Ctrl+Space doesn't seem to find anything in Global Keyboard Shortcuts - KDE Control Module
I searched with Ctrl and manually looked for anything that looked right.
oh ibus
 
@HyperNeutrino Oh on KDE it might be different
 
@HyperNeutrino Does this help?
 
wow nice you just ninja'd me with the exact same URL :o :P

that's not supposed to happen
 
@totallyhuman English, 2 bytes: no
 
By which I mean the arch package manager, not the video game
But still
 
i knew that at least
 
I don't need pacman on Windows >_>
 
1:03 AM
@HyperNeutrino Another idea I got from here: bind Ctrl+Space to something random and let it overwrite whatever binding already exists for Ctrl+Space, then remove it
 
oh hm interesting
 
oh wow it's easy to put stuff on pypi apparently; did not know that

Is there a way to pad a string with spaces in Python? Kind of like str.zfill but with spaces.
 
Maybe str.rjust?
 
Ah, perfect. Thanks.
 
Sorry, str.ljust().
 
But why the naming inconsistencies???? why????? for a language that's designed for easy usage...
Thanks. Now that I think of it, str.center was that I needed :P But thanks for the help.
 
You can pass in another argument for what character to use, as well.
 
1:47 AM
Ooh. Perfect.
So str.zfill(k, l) is just shorthand for str.rjust(k, l, '0')?
 
Yes. And you can actually use k.zfill(l) or k.rjust(l, '0') because methods called on objects are just called on the class with implicit self.
 
True.
 
I never liked that about Python.
 
Is this for paintbrush?
 
By "that", I mean the fact that "True" is capitalized.
 
1:53 AM
@totallyhuman no it's for a reference implementation for an upcoming challenge :P
 
true = True
 
I decided to bypass Sandbox this time (which is probably a little bit overconfident of my judgement), but now that I think of it I might want to sandbox it first.
 
@HyperNeutrino oh cool
@HyperNeutrino yes please do

wow that was fast
well I guess you just roasted my challenge :P
it took me quite a bit of effort ><
especially the code
which is 1117 bytes long because I didn't golf the reference implementation obviously lol
that's still shorter than my longest non-tarpit code-golf submission though :P
 
That's New Sandboxed Posts, not NewMainPosts...

Why are you making another one?" you may ask, but this one is going to be one of the most difficult ones (hopefully, anyway). Your quine must be "mutation-hardened"...

hey, this question was put on hold as unclear: codegolf.stackexchange.com/questions/132352/…
yet, there aren't any comments indicating any issues with the question
he's also posted a meta question: codegolf.meta.stackexchange.com/questions/13299/…
I'm going to vote for reopen, but @PeterTaylor @Mego @cairdcoinheringaahing if you could comment on the question or the meta post, that would be awesome
 
2:47 AM
@NathanMerrill I didn't vote to close, but I also haven't voted to open. Mainly because I don't understand the instructions very well. I'm not sure if its unclear but it certainly is confusing.

CMC: Given a string s and integers n, p > 0, for each char in s, copy it n times and append it with p spaces. Ex: 'abcd', n = 2, p = 1 -> 'aa bb cc dd '. Feel free to convert this into an actual challenge too if it seems hard enough

Q: "put on hold as unclear what you're asking" is itself unclear

CJ DennisMy question Ordered sequence of ascending integer combinations was put on hold despite receiving five good answers in the first 12 hours. It has also received a fair few upvotes, as have the answers. If people can answer it, how is it unclear? As of writing this, there are no comments on my quest...

 
Anonymous
 
3:55 AM
Right, Fission. I somehow forgot about Fission.
Probably because I've always used it in 1D mode. :P
 
@Dennis ;)
UB eleven
 
Here's a Fission standalone but yeah, couldn't find any where you consciously used made use of multiple lines (I would have expected a 2D lang as part of a polyglot but had trouble finding one)
 
is there any way to do powers of 3 faster than exponentiation by squaring
 
@ASCII-only probably not
 
4:11 AM
@LeakyNun chill my dude
 
@WheatWizard while I agree that it is hard to read and parse, clearly it is possible, as there are several answers to it.
Regardless, it is crazy to me that people would consider close voting a challenge without a single comment
 
I've already voted to reopen.
I had to read it about 5 times but I get it
I don't get the why part but I could write a program to do it.
 
I totally agree. It's really not a well-written question, and the output is bizarre

@LeakyNun :D +1 for cheddar

6:47 AM
@NathanMerrill I've answered the meta post, but I'm not sure it's really going to help the situation. When a question is that incomprehensible, a comment doesn't add anything to "Unclear".
@WheatWizard Start by exploiting "You may take this input however you like": I'll have a list of digits, please. Then apply algebra: b l=sum(zipWith(*)l[1..])/sum(l)
In fact, even if you take the input as a string that saves three bytes

@xnor mitchs fixed my anagol problem (hopping number), if you wanna resubmit Python there!
19 was missing, because I goofed up the reference solution. >_<;
 
9:18 AM
I think our definition of is wrong: "A prime number is a number that is only divisible by 1 and itself". That would include 1, since it is only divisible by 1 and 1. We should say: "A prime number is a number that has exactly two positive integer divisors.", IMHO. If you agree, I will edit the tag wiki.
 
Sounds good. Divisors are always integer, if you wanna be golf-y about it
 
@Lynn Great, I'll edit the tag wiki then.
 
I wonder how I’d word it…
 
I may wrap it between brackets though (such that it is clear): "two positive (integer) divisors".
Done, is better now :P
Is it the first time when the difference between Dennis and ME is bigger than 1k?
 
9:40 AM
Is LCM(range(1,n))+1 always prime? (where the range is inclusive on both ends)
 
LCM of a range?!
 
or just reduce by LCM
{1+∧/⍳⍵} in Dyalog APL
 
@Cowsquack It's not like I know APL :)
 
well ⍳⍵ creates the range 1 to the argument, and ∧/ is reduce by LCM
wait, that statement is false when n is 8
you get 841 which is 29 squared
 
: Difficulty rating on challenges and sorting filters by difficulty
 
9:47 AM
difficulty depends heavily on the language used
 
@Cowsquack An overall rating from the (registered) users that read it
I have edited in, feel free to rollback
 
Some good intuition to have: the answer to “is (some easy way to make big numbers)+1 always prime” is always “no”.

ok I think leaky knows jelly, actually, 05ab1e, matl, pyth, brachylog, j, golfscript, mathematica, retina, cheddar, r, python, c and java
are we sure he is the real leaky anymore? I mean, he hasn't shown considerable activity with some of the languages (in bold) before...ZOMBIE APOCALYPSE HAS STARTED NOOOO
@Dennis this is a possible hypothesis ;) :P
 
@EriktheOutgolfer I remember seeing frequent Java answer by Leaky
and some actually and c
 
I mean, 05AB1E? MATL? Mathematica? WAT
 
Matlab?
 
no matl
it's matlab-based golfing language
of course the other hypothesis is that he's learning languages secretly
 
I know, I was just asking if he knows Matlab
 
11:57 AM
don't think so (yet...booooo)
 
@EriktheOutgolfer Of course, I Know what MATL is.
 
I have some other hypothesis too where leaky is secretly learning languages
but then you wouldn't expect him to...buy mathematica would you?
 
@EriktheOutgolfer Sandbox.WolframCloud... ?
 
and another one would be that he is not an individual
 
Isn't this free?
@EriktheOutgolfer Good one.

(leaky mentioned something suspicious there...)
@Mr.Xcoder huh? I don't think dennis knows even a fraction of the languages leaky knows...he knows some other languages like julia...which...leaky might already know...
 
@EriktheOutgolfer But I think ME knows more
 
12:04 PM
also this is evidence something isn't going on well
@Mr.Xcoder you?
 
ME knows Mathematica, Husk, Grime, Retina, Jelly, Alice, GolfScript, CJam, Fission, Jellyfish, Pyth (I think), Python, Ruby
C++ (?), C# (?), Java
 
he posted a DAMN 15 ANSWERS there
and even worse, nobody outgolfed him A N Y W H E R E
 
@EriktheOutgolfer Are you talking about Leaky?
 
In the pivot challenge?

I'm really traumatized now
 
He/They is/are really going crazy there

@EriktheOutgolfer No, ME does

@EriktheOutgolfer But has anyone tried?
 
@PeterTaylor It's not even worth it trying
 
it's 15 answers there's almost zero possibility nobody has ever tried
@Mr.Xcoder I've outgolfed leaky in the past
 
@EriktheOutgolfer Not in a challenge where he/they posted 15 damn answers.

I mean, he's going to be THE NEW DENNIS

yeah I didn't say anything against that

I think I've used 10 languages professionally: C, Java, bash, JavaScript, PHP, C#, VBA, SQL (two variants), Perl, CJam. Plus, if you count it, the DSL language I created for one project.
 
@Mr.Xcoder nope I don't think so
in fact dennis is against such a thing (starred message):
8 hours ago, by Dennis
At this point you're just hogging the challenge.
 
My record is 2 answers/question
So yeah
 
@Cowsquack that's 1 answer with 30 languages not 30 answers
 
12:18 PM
@ATaco in your 3d thing I think there is an issue with how much you shrink it, because things seem to get thinner than they get shorter
 
I really should read more carefully
 
Oh, I actually have a record of 4 answers on my own challenge.
I feel better now :P
 
oh no I think I need psychiatrist RIGHT HERE AND RIGHT NOW I can't handle this anymore...I mean we know how fast leaky is but honestly 15 answers...that also requires fast internet connection (in the million dollar range)
 
@PeterTaylor but even unclear posts need comments saying "what do you mean by X" to allow the poster to help him to improve his post.
 
@EriktheOutgolfer Please don't overexaggerate.
 
12:21 PM
that's not overexaggeration
 
@EriktheOutgolfer leaky overexaggerated. But you do so too: "RIGHT HERE AND RIGHT NOW".
 
true
@Mr.Xcoder no that's intended to be like that
 
But, In the end, if you can answer in 15 languages, why not?
 
you're not supposed to be able to do that at all if you're a normal human being
