@EriktheOutgolfer the polish boxes?
 
yeah, but it's not very easy
 
 
1:35 AM
i should really do that quarterstaff to bf challenge i made some time
 
2:08 AM
@EriktheOutgolfer J does the hard parts
 
2:25 AM
@Pavel Next time consider using BFlak for Brain-Flak. Ambiguous abbreviation...
 
@user202729 context
 
I know but...
Anyway, how can it possibly work?
Comparison evaluates to True or False, [...] evaluates to a list, {..} evaluates to a set/dict.
None of them evaluates to a number.
(...) just return whatever inside it.
[]...
 
<<
 
@H.PWiz Good idea.
Well [] can be used for indexing too but...
 
True or False can be used as ints
 
2:28 AM
@user202729 Not mine, CatWizard solved it. Which inspired the CMC
 
@Pavel We have a bunch of snippet answers before the consensus.
 
@user202729 More context
 
@Pavel That was about "how can it possibly be solved"
 
Right. Do some scrolling. See WW's solution.
 
2:31 AM
@H.PWiz already tell me about it ...
I don't want spoilers...
and still can't think of a way how to create 3.
 
Neither can I. We were talking just about powers of 2.
 
C O N T E X T
 
@Pavel Stop it.
Still thinking how to create 1.
 
If you can make 3 I'd be pretty interested. I spent a long while trying.
 
Nevermind. Have 1 now.
At least singleton set/list is possible.
Then just repeatedly <<1 to get other powers of 2 right.
Now this looks like JSF, but in Python.
 
2:35 AM
You need to use >> as well to counter balance the <<
Can you make zero?
 
Yes.
Accessible things: (empty/singleton) (list/set), empty (dict/tuple), indexing, nonequal comparison, shift.
 
empty tuple
and I suppose function calls. However I have yet to get a function
 
Of course the 2 first ones can't result in a number, the 2 last one can only result in power of 2 numbers/boolean. given those inputs.
Indexing and function call...
Index can only be used for tuple or list.
 
Hm now I'm thinking about Haskell
Probably can't make numbers, but we can make some other things
It seems like < and > are unusable since they can't be balanced
And likewise with >> because << doesn't exist and we already can't use < and >
(<>) however is useable
It looks like I can just make lists of lists and empty tuples.
And I suppose a couple of rather uninteresting functions
Oh, () is a monoid as well.
But that isn't useful
 
You know we don't really need real integers, we can just nest lists
 
2:48 AM
Yeah, I can make Von-neuman numerals
 
Incrementing is easy, decrementing is just indexing with 0
Which is []<>[] in Py2
 
Py2?
 
Python 2, on mobile
 
Oh, I was still thinking about Haskell
 
Im sure it's possible there too
 
2:50 AM
Wait what the heck is (<>)?
It seems to be not equal to?
This shortens my code a good deal.
 
In Haskell?
 
In Haskell it is the monoid action
I thought we were talking about python
 
Yeah <> is !=
Only in Python 2, they took it out in 3
 
I was using []<[]>[] to produce false earlier. []<>[] is shorter
[]<[]>[(()()())] is valid python
That will be useful
 
I just lose a lot of work because of coredump ...
@CatWizard Didn't know that <> is supported in Python.
 
2:57 AM
I did not.
 
I've never seen it used in golf really
Maybe in restricted source
But yeah it's a thing
 
@CatWizard and short circuits.
@quartata It's no shorter than !=. Everyone just use what they know.
<> is only used in Pascal.
And Logo?
 
Yeah, I was already abusing short circuits I just forgot that python was lazily typed.
Haskell uses <> but for an entirely different purpose
 
@user202729 Because, annoyingly, text editors delete everything when it fails to save (for example when the disk is full)
 
Which text editor?
 
3:00 AM
For me... sublime text 3.
Just try it. (1) Open a file for editing. (2) While editing fill up the hard drive partition. (3) Save it. (4) Exit the editor.
Also: Anyone have xdiskusage? I know the (inodes) part is "file system overhead", but is it normal if it takes ~500MB?
 
Anonymous
@user202729 Don't forget SQL
 
Of course when saving you will get a "permission denied".
I think I should git add more often.
 
3:36 AM
@user202729 Or alternatively: When you see an error, don't exit anything.
 
@user202729 And QBasic!

AJFaradayAccording to this question a Superb Shuffle™️ is defined as a full deck of cards (including jokers) which follows this set of rules: No two cards (except Jokers) of the same suit are adjacent. No card (except Jokers) is adjacent to one of the same value. No card (except Jokers) is adjacent to o...

@ASCII-only for VSL do we want to do the thing where enums can have constructors
 
10:14 AM
@FrownyFrog yeah, I did guess it would be easy for APL_like languages...btw, it's apparently 38 in gs2 (credit tails), so that talks by itself: it's not very easy a challenge

@EriktheOutgolfer link?
 
not post-mortem yet, I dunno :P
 
ngn
@EriktheOutgolfer ok, never mind :)
 
you can try it out in K (Kona) if you want :)
just submit a .k file or choose K from the language list
 
ngn
@EriktheOutgolfer thanks; I don't think I k is likely to win this one - it's not so good at concatenating matrices with padding, J is perfect for this, APL could use mix (↑⍵)
I'll try golfing it for pleasure with ngn/k :)
 
@ngn APL doesn't exist :P don't worry about the score you will get, try your best
and it's probably for the best, because otherwise who knows what kind of GNU APL hell would have been in there
 
12:19 PM
@EriktheOutgolfer Is GNU APL actually so bad? I mean, they have some strange dfns, but other than that?
 
@Adám also, I think anagol counts in bytes, and APL would be a very different challenge over there (like, how to avoid as much unicode as possible)
 
@EriktheOutgolfer Ugh.
@EriktheOutgolfer Actually, that's an interesting challenge for non-ASCII languages. Imagine golfing Jelly with a penality on non-ASCII built-ins?
 
ngn
it calls itself "anarchy golf", but it's telling us what languages we can and cannot use... :)
 
@Adám it depends on whether anagol would've used Jelly's codepage or Unicode
 
Obviously, APL can't do much with +-*!?|=<>^~/\,.@&{}[]()#
 
12:26 PM
at least Dennis would've definitely wanted the former
 
@EriktheOutgolfer Uh, what?

A: Sandbox for Proposed Challenges

The random guyProgrqmming Puzzle andf Co9de Golf | codegolf Intro We all make mistakes. You, me, everyone. But not computers. They aren't making any mistake. Not even a single typo. Time to change this injustice. Task Your task will be to take a string as input, and display the string character by charact...

 
@Adám the reason Jelly is a successful golfing language (know what happened to ESMin?) is that it has its own code page, so, theoretically, the solutions are actually the bytes the Unicode chars represent, and not those chars themselves...so, if anagol uses Jelly's codepage, then we could upload a e.g. .jelly file encoded in JELLY
 
@EriktheOutgolfer he specifically said it'd be interesting golfing if there was a penalty for non-ASCII chars
 
@dzaima ninja'ed. Thanks.
 
12:31 PM
I'm replying to the "Imagine golfing Jelly with a penality on non-ASCII built-ins?" part
lol, if something like that was true for a PPCG challenge, the downvotes would've been merciless
 
@EriktheOutgolfer Yes, but it sounds like it wouldn't be a problem to use only the first 128 built-ins.
 
@Adám Jelly's encoding is, unfortunately, not an extension of 7-bit ASCII, so it's only the printable ASCII built-ins that can be used like that :P
 
@EriktheOutgolfer Only because it would be an unnecessary and unfair restriction. But a challenge designed especially for 8-bit languages, restricting them to 7 bits, could be fun.
 
@Adám and the challenge would be...?
 
@EriktheOutgolfer Either that, or maybe just the first half of the code page. Just a thought experiment at this point.
 
12:35 PM
@EriktheOutgolfer some of my favorite (non-ascii-art/KC) challenges have been restricted-source. I find it very fun to try to golf while there isn't access to a big portion of built-ins
 
@EriktheOutgolfer It does look to me like the Jelly codepage is an extension of printable 7-bit ASCII. (All ASCII is 7-bit…)
 
@Adám "7-bit" is used to avoid ambiguities with "Extended" :P
 
@EriktheOutgolfer Hence.
 
ngn
1:01 PM
@EriktheOutgolfer I have a 117-byte solution in ngn/k, now I can start golfing it...
 
@ngn no, not ngn/k, K (Kona)
 
ngn
@EriktheOutgolfer I know, I'm golfing for pleasure
 
@ngn ah OK then :P
but, if you want to submit it, I don't guarantee that you will not have to make adjustments for ngn/k → K (Kona) :)
 
@ngn 117‽ That's like entire financial application length…
 
ngn
@Adám haha, true :)
it's so complicated, I had to split it in two lines
 
1:04 PM
@ngn What is that famous APL expression that calculates all payments/interests of all types of loans/deposits?
 
ngn
@Adám idk, is it one that computes compound interest?
 
@ngn Something like that.
 
ngn
it would be trivial to translate that formula to apl
 
Kuhn poker is an extremely simplified form of poker developed by Harold W. Kuhn as a simple model zero-sum two-player imperfect-information game, amenable to a complete game-theoretic analysis. In Kuhn poker, the deck includes only three playing cards, for example a King, Queen, and Jack. One card is dealt to each player, which may place bets similarly to a standard poker. If both players bet or both players pass, the player with the higher card wins, otherwise, the betting player wins. == Game description == In conventional poker terms, a game of Kuhn poker proceeds as follows: Each player antes...
seem like a good idea for a king of the hill?
i was also thinking i could apply the many-worlds model to this to make the results deterministic

Q: The Jumping Up Sequence

AdmBorkBorkConsider the following sequence: 0 1 3 2 5 4 8 6 7 12 9 10 11 17 13 14 15 16 23 ... Looks pretty pattern-less, right? Here's how it works. Starting with 0, jump up n integers, with n starting at 1. That's the next number in the sequence. Then, append any numbers "skipped" and that haven't been...

 
2:08 PM
@Mego 1. poorly-written as in source code? 2. well the vast majority of languages out there are quickly-written, insanely hacky esolangs
@Downgoat ping
@Downgoat maybe. but only if they're compile time
@Downgoat former. unless the latter has some kind of usecase i'm not aware of?
 
2:30 PM
@ASCII-only Yeah, there is no way for it to know that the list is constant.
 
@CatWizard no way?
 
How would it?
 
i guess it would be kinda possible in interpreted haskell but not compiled haskell?
 
Yeah. Or I suppose if !! was given access to the underlying representation it might be able to do reference checking
But even then, that would probably make normal list indexing slower.
 
in other languages you could make it a subclass of List, but Haskell probably can't do anything like that in a sane way
 
2:34 PM
Haskell lists are parametrically polymorphic, so there are subctypes of forall x.[x], but for example [Int] does not have any subtypes, nor can they be made.
 
@CatWizard I don't get it. Are lists not all constant?
 
[1,2,3]?
 
Oh, you mean as in compile-time constant?
 
Uh, no I mean contains only one thing
 
...
 
2:43 PM
[1,1,1] is constant
 
:O nice, you can have any head and (looping) tail
@CatWizard what's the third last line for
 
(Looplist [] (head:_)) !! 0 = head?
Oh yeah, that's not needed
 
2:59 PM
also, re: the recursion, i'm assuming Haskell is (quite) heavily optimized for that?
 
Haskell is optimized for recursion a good deal
 
@CatWizard I don't think that's what constant means
 
so kinda like prolog
@Pavel well at least not in conventional programming terms, yeah
wait.
actually haskell's pattern matching looks kinda like prolog's here
 
3:13 PM
@quartata did frowny know you were baiting him for that tweet
also what deepfryer do you use? gimp?
 
wasn't a bait, i just thought it was funny
i used this because i was in a hurry deepfriedmemes.com
but usually i use imagemagick for effects
 
3:29 PM
@CatWizard How could a program both terminate and make an infinite list?
 
@AdmBorkBork it doesn't have to be an actual infinite list
it just has to behave like one
 
@AdmBorkBork Haskell lists are basically generators
 
@AdmBorkBork either a generator, or a supertask
 
@Mayube but actual programs can't be supertasks :P
 
@AdmBorkBork A function can accept a infinite number of inputs but doesn't need to evaluate all of them to be used. The same with a list, if the list is lazily evaluated we can check the place of any specific index just fine.
 
3:30 PM
Apparently I'm showing my ignorance.
So it'd be like returning a closed-form lambda?
 
I'm not sure what a closed form lambda is.
My current haskell answer builds an infinite list, and then makes a function that indexes that list.
 
@AdmBorkBork I know you use PS, which is kinda .NET, do you know how an IEnumerable<T> works?
 
That sounds like it would be OK, but I'm trusting you guys ain't pulling my leg. :D
 
should I edit it into the question?
 
@Pavel OK, that kinda makes sense.
@CatWizard Sure. You could word it better than I could.
 
3:38 PM
@AdmBorkBork Well there you go. Yes, this means list indexing in Haskell is O(N).
 
@AdmBorkBork closed-form lambda?
@Pavel since they're linked lists (IIRC?)
 
They're either linked lists or generators
 
They're somewhere between linked lists and generators
regular linked lists can be infinite btw, since pointers are basically a form of lazy evaluation.
 
@CatWizard hmm. i wonder how useful infinite lists (and variations of them) would be in real life applications
 
I'm sure they are used. Especially when it comes to haskell.
 
3:46 PM
I don't think your infinite list is generated correctly. Around x=50 it should go 46, 57, 48
 
Oh hm, that's probably my fault.
@AdmBorkBork Wait why?
Shouldn't 47 be between 57 and 48?
 
Because 47 was already seen at the jump from 37 to 47
 
@Pavel you can use Data.Array for when you need O(1)
 
Ok I think I miss understood the question.
 
4:17 PM
Husk's infinite lists knock Jelly out again >_>
 
4:33 PM
@CatWizard hmmmmmmmmmmm would it be possible to make a class like Looplist but with limited length
 
lplst
 
@AdmBorkBork what's this
 
A more limited length Looplist. ;-)
 
@AdmBorkBork :|
 
Well, I think I'm funny.
 
4:42 PM
@ASCII-only What do you mean by with limited length?
 
@CatWizard like as in the constructor takes in length of the list and any higher than that errors
 
How is it looped though?
 
@CatWizard *with limited length
 
@CatWizard like Lengthlimitedlooplist [1, 2, 3] 7
it'd loop but only work for indices < 7
 
This can be made yes.
 
4:52 PM
@quartata Do you know how Haskell's FFI deals with mutable collections?

@ASCII-only There you go
 
What's {-# Language GADTs #-}?
 
@Dennis Hi, do you mind if I edit some of your very mathy answers to use MathJax?
 
@Pavel It turns on the GADTs language extension.
 
Ok, so it's still Haskell. Not a different language.
 
4:53 PM
Its technically not haskell but still GHC haskell since that's a compiler pragma
Something like Hugs won't compile that
 
@Mr.Xcoder Go ahead. :)
 
5:14 PM
Anyone know the name of Bash's <() operator (so I can google it)?

AdaephonThis is called process substitution. The <(list) syntax is supported by both, bash and zsh.

@Dennis In your answer here, if I understood it correctly, ∛x² was supposed to be ∛(x²), right? Let me know if I've gotten that wrong though and I'll happily ammend it.
 
@Dennis Maybe NaN stands for Not a NaN
 
@Mr.Xcoder x is positive, so it doesn't matter.

hah, just as I read the previous question you asked to Mego...nothing important, move on
 
what, nothing?
 
@EriktheOutgolfer run. It's the correct answer but has way too many newlines

the "Output will be here" placeholder is still there, so that can't be the case...do you need ES6 to run it now?
 
@EriktheOutgolfer oh classes is an ES6 feature so yeah
 
so I probably need Firefox Quantum to run it
no success
maybe you have forgotten something?
 
@EriktheOutgolfer ?
 
wait...another Firefox update downloading...
let's see first before accusing :p
yeah, that was apparently the issue lol
but...the newlines don't look like they are in valid places

@EriktheOutgolfer (searching each character) lead me to z = zip, so obviously jelly will be winning with it's trickery
 
that's not really what's going on here, it's the (full program) part that mostly is

@EriktheOutgolfer I mean every other thing is some generic/needed thing so zip + jelly trickery must do everything there
and I know 0 jelly so :p
 
there's no one trick
first of all, ŒḄ is normal palindromization
 
@EriktheOutgolfer that much I know. Everything else is what's confusing me
 
however, ŒḄ is one of the atoms with the property that they make a range like R does when getting a number as an argument
 
9:21 PM
@Mego Is there a possibility that it might be re-disabled in the future, making answers with MathJax look bad?
 
e.g. 4.4ŒḄ -> [1, 2, 3, 4, 3, 2, 1]
4.4R -> [1, 2, 3, 4]
@dzaima now, means "the link right to the left", so it becomes ŒḄ
is simply map (ach) here, so the result is the ŒḄ€ link, that is, do this to every integer in the list
z⁶ is simply zipwith with = space (since the program doesn't accept a 4th argument)
Y is join with \ns
 
@EriktheOutgolfer so that's the jelly trickery that's saving all the bytes here
 
now, since this is a full program, and \ns are characters ('\n'), the output will not appear like [1, 2, 3, …
instead, since there are characters (or empty strings, []) in the list, the list is flattened, every element gets converted to its string representation and then everything is joined into a string
 
so if there was a jelly-structured canvas the answer in that would be 6 bytes o.O
 
the output is stringified
lol wanna join JHT? (mildly inactive atm)
 
9:33 PM
@EriktheOutgolfer eh idk if I'm up to learning that monster (and I'm just about to disappear anyway)
 
just join and you'll be assigned level 0
that is, if you wanna learn Jelly of course ;)
wait, why will you disappear?
 
@EriktheOutgolfer 00:34 here + holidays
 
ah, I thought you meant you'll disappear from the face of PPCG for some while
 
@EriktheOutgolfer well if 3-4 days counts as a while then yes
 
wait why lol parents don't allow internet?
or you just wanna relax deeply?
 
9:37 PM
@EriktheOutgolfer we don't have internet in our countryside
 
um, won't data plans work either?
 
@EriktheOutgolfer I'm too lazy to change plans to something that contains internet for the couple days in a year I'd need that :p
 
@dzaima you only use Wi-Fi from your phone? o_o
 
@EriktheOutgolfer 99% of a day I'm either at home or at school or somewhere else there's wifi (and I don't need internet enough to care about the 1%)
 
@dzaima if you say that aloud, you might get a few weird looks...
but yeah, me neither :p

@Mego It seems a bit risky to use it, then :-/
 
I heard today that NULL on old Cray systems was -1.
This is the worst thing I've ever read
 
@LuisMendo then why did we enable it ;)

@LuisMendo I like to live on the edge :P

hm, has anybody noticed that, while Martin Ender's user activity has declined, Doorknob's user activity has recently raised? (can't know about mod activity)
 
martin is probably busy IRL, doorknob is probably off for the summer now
yep, looks like doorknob still has 1, maybe 2 summer vacations left
 
uh, are they counted?
 
@EriktheOutgolfer huh, I didn't realize he started being more active recently
 
he == you, for the record
