@Neil ^ If this is correct
 
Anarchy Golf just reached 1337 challenges
 
@Fmbalbuena I don't think you can get to 2**128 in unary in Charcoal
 
@Neil What i should do now?
 
12:30 AM
just add a cast
oh wait I see what you did
 
you're just printing 1 in a loop, so every refresh counts up in unary
I guess you could Multiprint instead of Print, and then increment the variable
 
@Neil I will do
@Neil Is there a way to golf W¹«?
 
no I don't think so
 
@Neil Edited, any ways to golf this?
 
12:42 AM
MapAssign(Incremented, x)
(and you'd forgotten to update your TIO link with the cast, not that it matters if you change it again anyway)
now I think I remember that someone mentioned sleep
 
12:56 AM
@Neil Thanks
 
that's right I finally did it
@Neil sleep? what's that?
 
1:16 AM
 
Served on an octagonal plate obviously

@thejonymyster he knows too much. Seems we'll have to... reeducate him
 
@thejonymyster looks like all online interpreter services need a physical office
First the RTO department now this
 
1:21 AM
@lyxal just you wait until I figure out where I put Ginger Industries HQ
 
@GingerIndustries Not all people taste the same
 
@user Excuse me
 
I was going to make a yo mama joke but never mind
 
@user no no back up to the part where you know what people taste like
shit I never expected to say pt. 1
 
I mean if one person eats McDonald's for a week and another eats tofu for a week, their innards will taste different
 
1:25 AM

It's like saying all chicken taste the same. Of course they don't taste the same, they're all unique animals with their own personalities and tastes
 
@pxeger I found the ATO building
It totally isn't an edit of a picture of the Australian Tax Office which just happens to have the same acronym
 
omg you just doxxed pxeger
 
Whenever you use ATO, an employee in the building runs your program and sends the results back
For each new language, a whole team of specialists are hired for running programs in that language
 
You know, that's a surprisingly fancy logo for a government building
@lyxal Ah, is the balding dude the COBOL guy? :P
 
1:28 AM
@user correct
@user I think it's an old logo - they seem to have moved to a new building
 
Could you get some blueprints for this building? I'd like to hack it
 
No
 
Why not?
 
I'm not gonna let you make me pay tax
 
Don't worry, I'll make all Australians but you pay tax
Because I obviously have the power to do this
 
1:30 AM
That's what they all say
 
All? :o
 
They all claim to be "working in my interests and they won't make me pay taxes"
But I know that they're just government officials trying to catch me out on tax evasion
Well guess what nerds? Lyxal ain't paying no tax
(for legal reasons that's a joke)
(even though I don't actually have any taxes to pay lol)
 
LMFAO what a loser not even earning money 😂🤣😂🤣 /s
 
Well at least I don't have any taxes due
Paying taxes is for nerds
Gamers dodge tax like they dodge women

> dodge tax evasion
 
1:33 AM
shhh
 
Gamers don't have to dodge women, y'all naturally repel them :P (/s)

Q: Generate Matching Regexes

user197974Write a program that takes two lists of strings and generates a javascript regex that fully matches all the strings in the first list and matches none of the strings in the second list. To be specific when for all stings in the first list str.match(\[your-output]\) must produce a match for the fu...

3:49 AM
1 -= x; // x = 1 - x
Discuss.
 
lvalue required
 
no what it should do is assign to the value of 1
so when you use the literal 1 in the future it yields the modified value
anyway i would like an inverse op-equals thing but it'd need to be unambiguous
so for eaxmple a -= b is a = a - b, a ? b is a = b - a, but it'd need a new symbol
 
@hyper-neutrino golfscript time
 
wait what
 
@taRadvylfsriksushilani wrong. x is assigned -1
96 -= x; // x = -69
Reversible javascript when?
 
4:00 AM
@hyper-neutrino Try it online!
 
@Razetime cursed
 
golfscript truly ahead of its time
 
4:12 AM
@hyper-neutrino a -@= b
?@= should just be reversed augmented assignment in general
 
@taRadvylfsriksushilani amazing, every imperative language should have it. Its just an amazing breakthrough, /s
i would assume that cursedness to be JS
 
@lyxal Following that logic, a <op>þ= b is a = outer_prouct_by(<op>, a, b)

Q: Is this hexagon symmetric?

alephalphaTLDR: This is the hexagonal version of Is this square symmetrical? Given a hexagonal grid, decide if it is symmetric. The shape of the grid is a regular hexagon. Each cell in the grid has two possible states. Let's only consider reflections and rotations. Here are all the possible symmetries: Re...

 
@NewPosts I'm going to go out on a limb here and say that no, it isn't symmetric.
 
no it is
 
4:22 AM
It really isn't
 
oh then i agree with you
 
thank you
 
att
4:41 AM
that's symmetric
 
how?
 
@taRadvylfsriksushilani this would be a good feature, and is efficient in the sense that it turns what would be an obvious error into something useful
 
att
5:03 AM
@PyGamer0 reflect through the screen

Q: Shortest way to coerce to array

ThomasReggiGiven a variable a (non array) or (any[]) convert to (any[]) function example(s: string | string[]) { const e = [...(Array.isArray(errors) ? errors: [errors])] return e }

 
@NewPosts just call vyxal.helpers.wrapify lol
ez
 
6:29 AM
huh, that .flat() trick could come in handy all the time, but I've never seen it before
Arnauld's discovered it already, of course
(go give that some upvotes, +1 is not enough)
 
6:42 AM
...saw the deleted tip below it, and js has regex literals??
i assumed maybe not since the tip was deleted but then i tried it on tio and it worked
 
yep, it does
x=/stuff/flags
if i was making js id make regex literals == things they match
but not === ofc
 
@thejonymyster come to Ruby, where the exact inverse is true
 
i feel like that would make more sense than some of the other coercions == does
and yeah wait is there no shorter way to match than with the .exec

Fun fact: banging your head on a bit of wood hurts
 
9:39 AM
oh
 
10:21 AM
@pxeger you got me
 
10:40 AM
@emanresuA idiot. Why'd you bang your head on wood? Gamers bang their heads on non-wood products 😎
 
And epic coders bang their heads on their laptops.
Maximum Epicness reached.
 
Wow ur cool and epic
🕶️👈🙂 Take my sunglasses because your maximum epic
 
thanks 🕶️👈➕ ➡️😎
 
what is inner product?
 
@PyGamer0 marketing nonsense for products.
 
10:51 AM
:/
 
You know, like those products that claim to help you "get in touch with your inner product"
 
what
 
(it's a play on the concept of people wanting to "get in touch with their inner self")
 
@GingerIndustries Just realized that you can use my Antirickroll program to make my AntiAntiRickroll an AntiAntiAntiRickroll
so
CMC: Make a program, given an AntiAnti...Rickroll string to prefix an "Anti" only if the number of Anti's in the input is odd.
 
11:08 AM
lambda n:'Anti'*(len(n)/4%2)+n
Any byte-savings possible?
 
@ThisFieldIsRequired I get this error: TypeError: can't multiply sequence by non-int of type 'float'
 
probably meant to be in python 2
 
no
just add a / before the /
I never use python 2 on codegolf.
for that matter I never use python 2 at all.
 
@ThisFieldIsRequired nice
 
11:11 AM
You even return (if the number of Anti is even) GingerIndustries own program to annoy him
@lyxal thanks
 
11:28 AM
@lyxal then why hexagon is symmetric??? this is useless???

Q: How many times can I skip a stone?

Wheat WizardLet's have an list of positive integers [6,1,9,3,7,4,6,3,2,7,6,6] this will represent a river. We would like to skip a stone across this river. We can throw the stone as far as we want and whatever number it lands on it will skip that many places. So if we start by throwing it 2 spaces, it wi...

@mathcat I was halfway finished recording the clips for the film
and then of course, I had to change my pfp
@pxeger It has to prefix an Anti
 
yeah I thought it might, the prompt wasn't very clear to me
just add +s for 2 bytes then
 
You are disallowing me to make an AntiAntiRickroll
 
lambda s:'Anti'[:len(s)&4]+s

ah thanks

I am back
@mathcat what did I do to deserve this
 
:) nothing
 
@mathcat then why did you do it
 
but now I have a new superweapon: lambda s:'Anti'[:len(s)&4]+s
 
@mathcat darn darn darn I need to get myself one of those
just a sec >:)
 
2:54 PM
@GingerIndustries I wanted to prevent you from using my own code against me >:)
lemme see if this stops my antirickroll
Ok. test time
umpf
it works
How can I star a conversation?
 
@mathcat Just star a message
 
oh ok
 
5. This video is cool
 
CMQ: Can a language that can take a finite (but unlimited) amount of input and give a finite (but unlimited) amount of output be Turing complete?
 
a Turing machine doesn't need any I/O other than halting
so yes
 
Oh great
 
@mathcat this is how many times do you rickroll?
or something?
 
3:22 PM
idk why?
 
What is 5?
 
A number?
 
Why you put 5?
 
ooh
extended this
 
6. "extended this"
@PyGamer0 Hi
 
3:26 PM
hi
 
@PyGamer0 Do you know some golflangs? (not counting dinoux and flax)
 
i guess so
jelly and vyxal
 
7. Any feedback?
 
just out of curiosity, did log4shell affect code-golf? I was not here when it happened, and just today, I saw that StackOverflow blog post
 
3:29 PM
log4shell?
 
whats log4shell

do you mean log4j RCE
 
it was an exploit in log4j

@smarnav i dont know, i dont think anything happened
except for some log4j discussions
 
hmm... I was just thinking that some language might have used it...
 
8. New Posts and Sandbox Posts messages
^ Then
Don't try this now
 
@smarnav why would golflangs use it lol
well maybe for debugging
 
what's log4j?
 
@mathcat Minecraft virus
IIRC
 
3:33 PM
a logging library for an esolang java
@Fmbalbuena no lol
log4j -> logger for java
 
9. pings, Looks like green, so this is link to rickroll.

5:55 PM
@Neil When the matches are replaced by $*, why this makes number unary instead of *? I think $ is for escaping characters.
 
Ooh, I might repcap today!
 
@taRadvylfsriksushilani please can i gain 40 rep?
by 4 votes in my answers?
 
I'm not sure what you're asking me to do
 
I want to gain rep.
 
You can gain 40 rep from 4 upvotes, yes, but I won't just go upvote you because you ask me to
 
6:01 PM
@taRadvylfsriksushilani i downvoted your answer.
(jk, I will undo)
 
stop demanding people to do shit
votes are intended as a form of quality control
you upvote things you think are good and should be seen, you downvote things that you think are bad and that is SE's content rating system
7
people won't upvote you just because you asked them to
and you aren't allowed to downvote things just because you don't like the user
 
@hyper-neutrino sorry
 
I hate when I have an idea for a challenge but I just can't figure out how to word it
 
@taRadvylfsriksushilani Oh, i know that feeling
 
@taRadvylfsriksushilani Saturdays are weird. Sometimes I they are completely dead and sometimes I repcap seemly out of nowhere.

Q: What if someone posts a translated answer of another Answer?

FmbalbuenaFor example, take a look at this answer, This answer is another answer but translated\$^1\$. What I should do if there is a translated Copy answer, Should I flag? 1 Only Language derivatives

 
see this is what you use downvotes for
 
@taRadvylfsriksushilani This is the answer^1 the most upvotes with 0 net score
1: answer, not question
@hyper-neutrino ???
 
@Fmbalbuena first of all, I don't care about upvotes to my answer, i spent literally 20 seconds on it. second of all, I didn't downvote your question
third of all, even if I downvoted your question, you upvoting me won't make me change that decision
 
1. HN was referring to the answer you linked to, not your question
2. This is exactly what HN was talking about with not bargaining with voting
 
6:18 PM
don't try to bribe me with votes, you're not gonna get anywhere with it, trust me
6
 
Also don't link answers in meta posts like that. The discussion can happen without it and when you include a link you are basically encouraging people to downvote a specific post.
 
@WheatWizard thanks
 
@Fmbalbuena depends on the Retina version. In Retina 0.8.2, $* is the character repetition operator. In Retina 1, * is the string repetition operator, and $* is a literal *
 
@Neil Why you used Retina and Charcoal to answer every challenge?
@hyper-neutrino i broke
 
6:42 PM
The bottom-most nomination on this doesn't have the name of the person who wrote the nomination. Should it be edited in, or are ""anonymous"" nominations fine?
("anonymous" in quotes because of revision history)
 
@Fmbalbuena because I like them more than other languages
 
Three people agree with you, so I'll post

are you sure this'll work?

You don't
 
@user then why is that an option
 
That's the thing, someone may make a silly typo like sudo rm -rf / home/foo and you don't want / to be deleted
 
@GingerIndustries freedom
 
Oh are you saying that even sudo rm -rf --no-preserve-root / should not be allowed?
