wow, @Mr.Xcoder, 7 undeleted and 5 deleted answers...
Congrats on a tricky question
@AdmBorkBork Half of those are me >_>
@MagicOctopusUrn huh
only one is yours
ok, windows just hates me. The fonts have gone nuts
@EriktheOutgolfer Ohhh, wrong question. I had 2 deleted on his Cops and Robbers, just undeleted my other a minute ago.
um the cops and robbers is stewie's
20:11
@EriktheOutgolfer I have serious ADHD problems.
@dzaima reboot
the windows logo doesn't appear at the lower-left, that's weird
@AdmBorkBork IMO the challenge is so simple that many have overlooked the specs
Okx
Okx
@dzaima why is sogl written in processing? isn't that a visualization language?
@Okx it's the language I know the best :p
Okx
Okx
it'd be easy to port it to java and that would be a more appropiate language
since processing is kinda like java
20:17
@Okx eh, too lazy. And what's the point either? Processing is nicer and sometimes less verbose
@EriktheOutgolfer I'm using 7+ taskbar tweaker, that's why (it also adds seconds to the time, but that's not very visible). Restarting (as expected) fixed it, but it's still strange
oh
because otherwise it would've represented some very urgent need for a reboot
(shutdown -r at "Run" prompt opened with Ctrl+R)
CMC: Given a list, return the elements that are not unique.
[4,5,5,5,6,7,3,2,7,3] -> [5, 7, 3] (irrelevant order)
Erm, isn't that ones that are unique?
@AdmBorkBork >.< corrected

@Mr.Xcoder 05AB1E, 4 bytes: ¢≠ÏÙ

@Mr.Xcoder PowerShell, 37 bytes
BTW it's a good challenge for Jelly learners (hint, hint @AdmBorkBork)

I currently have 7 bytes, golfing.
@Okx Ohh, nice

Probably waay too long

Q: #Is AutoCompletion Valid and Iff so, how does it affect Byte Count

Taylor ScottIs AutoCompletion Valid and Iff so, how does it affect Byte Count We shall first define AutoCompletion as being the addition of any code segments to the code before either compile or run time as the direct result a keystroke and independant of outside information. Note that this is not the same...

@AdmBorkBork Nice, let me golf mine too.
@Mr.Xcoder APL, 15 bytes
@Mr.Xcoder Jelly, 5 bytes
@AdmBorkBork Please I won't look at the spoiler but tell me you don't use œ^ again...
20:33
I do use that
Cause I have absolutely no idea how it works.
facepalm ಠ_ಠ
@AdmBorkBork CMC: Solve my latest CMC without œ^.
@Mr.Xcoder It's the union of the two sets minus the intersection of the two sets
what question is this for, again?
13 mins ago, by Mr. Xcoder
CMC: Given a list, return the elements that are not unique.
i.e., things that are in one or the other but not both
20:35
I got it. Basically (A \ B) + (B \ A).
Known as "disjoint union" or "XOR"
As a reference here is my 7-byter.
@AdmBorkBork Now I have 4 bytes.
Okx
Okx
i prefer the 4 byte one
20:40
Now comes the question which

@Mr.Xcoder APL, 12 bytes with weird spacing
What is ⋄'' supposed to do? Join by spaces?
@Mr.Xcoder Try it online! - 4 bytes?
@Mr.Xcoder that has a "ternary operator" - 1≠≢⍵ is the condition, :⍺ - truthy case, ⋄'' - falsy case - return an empty string
20:48
@MagicOctopusUrn huh?
@dzaima I know what ternaries are, didn't spot the : though. Thanks
@Mr.Xcoder The CMC
@MagicOctopusUrn They must be deduplicated (see the test case)
Oh, 6 bytes then.
@MagicOctopusUrn 5 here
12 bytes with zeroes instead of empty lines
20:51
@Mr.Xcoder Try it online! (couldn't edit the old one). AFAIK, there is no 1-3 byte way to get non-unique chars in 05AB1E.
@MagicOctopusUrn I think ʒ¢≠}Ù would work for 5.
Oooo what's the command?
@MagicOctopusUrn Falsified (a ≠ 1)
Woo! Finally! Something other than _ for that!
@MagicOctopusUrn So it's been added recently?
20:54
@Mr.Xcoder Extremely recently, anything up at the top is basically within the last 2 months.
CMC: Take a string as input, and return the smallest substring you could remove to make it a palindrome. Example: `800233008 -> "2".
@MagicOctopusUrn Is there anything like "Intersection" in 05AB1E?
@Mr.Xcoder a.keep(b)
Sorry I meant difference
(set difference)
Errr, delta?
Mmm... no, because "a with no b's" would result in [3,3,4,5], [3, 4] -> [5]
@MagicOctopusUrn No, Bagwise subtraction. [3,3,4,5], [3, 4] -> [3,5]
IK... That's why I asked
20:58
Unless - vectorizes like that?
No, - subtracts each from each
I wanted to use that earlier too, probably for the same challenge haha.
[1,2,3][1,2,3]- -> [0,0,0]
@Mr.Xcoder м is push a.remove(all elements of b), but it seems to only work on strings
Hey Guys, if you haven't already, would y'all mind casting a vote on this question - it would be greatly appreciated
20:59
You could use sorted lifted a with no b's? If they're the same length list >_>
@Riley No, not what I am looking for. It should keep multiple occurrences ([3,3,4], [3] -> [3, 4])
> documentation
> .b = pop a push **letterified**(a)
Really 05AB1E?!
.b? That used to be á (and still is) wonder why that was added..
If 05AB1E would have better built-ins for array manipulation...
@MagicOctopusUrn Do you already have a working solution in 05AB1E?
@Mr.Xcoder the best solution I can think of is repeatedly replacing the first element...
It seems rather hard.
21:04
@Mr.Xcoder Which challenge?
@Mr.Xcoder That's definitely one thing it really struggles with
@MagicOctopusUrn The CMC.
@Mr.Xcoder Which cmc

@Mr.Xcoder I'm still working but I was thinking Œʒ¹õ.;ÂQ}, did not work as expected.
Whooooops... All I needed was a swap: Try it online! - 12 bytes.
Actually, that's more complicated of a challenge than I initially thought...
That answer isn't correct.
CMC: Given N, solve the Coupon Collectors Problem for N coupons
Because if a substring exists multiple times, it can give an invalid answer.
@Mr.Xcoder I honestly cannot think of a good way to do it in 05AB1E now, that was my only idea.

Holy crud, sorting by "votes" and going to the last page is lolzy: codegolf.stackexchange.com/questions/123808/… Poor kid got -30 and +3 on a simple challenge lmao.
21:39
@Mr.Xcoder huh, chat gets formatting you can't use in answers?
@Neil I think it has to do with the HTML-based tags not working in chat. Maybe not, that doesn't work anywhere, odd.
unrelated, but not knowing when chat will scroll up and when it will open the transcript is annoying
I wonder if my answer is 1/2 of the uncracked because nobody knows groovy, or if it's actually good: codegolf.stackexchange.com/questions/146926/…
I spent awhile on thinking of the most annoying way to do it.
hi, is there a good place to check if a new challenge is a reasonable one?
@AndrewHill we have a whole sandbox! https://codegolf.meta.stackexchange.com/questions/2140/sandbox-for-proposed-challenges?cb=1
Post your challenge as an answer to that meta-question.
@AndrewHill The bot will then pick it up and post it here, which we'll see. If you haven't gotten a response in a day post it again here.
@AndrewHill Lmk when you do! I can help review it with you.
21:51
done :)
any feedback for this sandboxed post? It seems like it would have been done before, but I can't actually find anything that makes it a dupe...

Most of these are just Guides to NodeJS
Especially the first one.
Anyone know what "Can" means as a title? Title as in Lord/Lady/Mrs./Professor/etc.

Golfing language with built-in kologmorov complexity features baked right in?
Stuff like base64 or similar text->binary literals, the ability compactly define and apply huffman encodings, etc
Something like bubblegun but actually useable for non-trivial input-dependent code golf challenges
*bubblegum
@eaglgenes101 Generally the best languages for kolmo are 05AB1E, and SOGL, and less frequently V. Jelly also tends to be pretty good at it
Cinnamon gum was specialized for kolmo, and it's kinda like a more advanced bubblegum, but I don't know if it's still super useful
Oh yeah, and of course charcoal. Especially if it's more specifically ASCII-art kolmo
Is cinnamon gum still maintained?
@eaglgenes101 I don't think so. But if you're interested in using it, you can always ask @quartata about it
Why does the New Sandboxed Posts bot have such an odd icon?
is it user-made?
@DJMcMayhem Code formatting doesn't prevent ping
@NoOneIsHere Yes
Same with NMP
23:37
Meta or Main?
@Pavel Are you sure about that? Could you try it with mine?
@DJMcMayhem
Huh
TIL
@NoOneIsHere Both
Languages who constrain themselves to a byte-based code page aren't really amenable to extension
23:57
And besides, if you have the source code compressed, nobody really cares that UTF-8 has more overhead than is really necessary for source code
Any golfing languages that are taking feature requests?
