It's called NetKoTH.
Does one's github profile pic EVER update?
yes
wait what do you mean?
@Cowsquack How long does it take? It didn't update in 30 minutes!
I changed it saved the new profile info, and I've been waiting for ~30 mins, and it didn't refresh.
I think it also took long for me
If I click edit profile again, the new image is shown in the image box, but once I stop editing it, it suddenly changes to the identicon.
17:04
give it time
CMC: (computer science/math question, not programming) What is the number of possible binary trees that have N leaf nodes?
I consider 1/2 an hour a lot of time >_<
1 and 2 are both 1. 3 is two. I'm not sure about 4
@mınxomaτ I'm resuming work on my quantum-gate optimizer thing. My previous version was only for single-qubit/controlled-phase gates, and was based on rotations of the single qubit's bloch sphere. This time I'm going for a more holistic matrix-based approach, which ideally will be able to handle an arbitrary number of qubits.

17:08
@DJMcMayhem I think it is also two, 1-1-1-1, 1-1-2
@Cowsquack context?
There's definitely more than that
It's hard to describe trees in text though
@ckjbgames you can click on the little reply icon to the left of the message
ooh, and 1-2-1
@totallyhuman i think i did
17:10
are 1-((1-1),1) and 1-(1,(1-1)) different trees?
Anyways, context?

CMC: (computer science/math question, not programming) What is the number of possible binary trees that have N leaf nodes?
@Cowsquack Yes
@Cowsquack thanks
so four now
17:11
What about ((1-1)(1-1))?
do you mean separate trees?
@Cowsquack Someone could find a way to make it a question.
No, that's one tree. Left-left, left-right, right-left, and right-right
So a perfectly balanced tree
but doesn't it have 5 leaves if you include the starting leaf?
You know what's balanced? - ((())())
@Cowsquack leaf nodes
In combinatorial mathematics, the Catalan numbers form a sequence of natural numbers that occur in various counting problems, often involving recursively-defined objects. They are named after the Belgian mathematician Eugène Charles Catalan (1814–1894). Using zero-based numbering, the nth Catalan number is given directly in terms of binomial coefficients by C n = 1 n + 1 ...
> Successive applications of a binary operator can be represented in terms of a full binary tree. (A rooted binary tree is full if every vertex has either two children or no children.) It follows that Cn is the number of full binary trees with n + 1 leaves.
So only counting the nodes that don't have any children
Is it just Catalan numbers?
I guess so
17:20
Don't undelete a question that I deleted. @dzaima @HyperNeutrino @totallyhuman
I didn't undelete it, I only asked
If you think it is ready to be undeleted and posted, please discuss it with me, don't vote without consulting me
@dzaima you voted to undelete
I placed an undelete vote on it. Sorry. (It seemed okay to me after you clarified the specifications)
@dzaima sorry wrong person
17:21
@cairdcoinheringaahing dzaima has <4k rep; there's no way that that's possible.
I have <4k rep as will
I can undelete, I didnt
oh wait you can?
Was it 2000? :P
@HyperNeutrino yeah I just realized that it was @programmer5000 not dzaima
17:22
Ah okay.
Regardless, sorry for the undelete vote (I realized later that I should ask you first but you can't un-undelete vote). It looks good now to me though, so nice question :).
@HyperNeutrino if you say so. Personally I had a few more edits in mind, and I'm still posting this on meta, but I'll see how that challenge goes.
If you think it's not ready yet (since I'm not the one who made the challenge so my judgement won't be as accurate), you can delete it again (I hope) and I won't undelete it this time, and post it into Sandbox.
@cairdcoinheringaahing is a unicode dash used in the challenge on purpose?
Does anyone here like to give feedback to Sandbox answers? I could use some

@EriktheOutgolfer wow. lots of golfing there.
I mean, Jelly beats 05AB1E in a challenge now O_O *head explodes* *rip head*
@EriktheOutgolfer never thought that could happen
@EriktheOutgolfer Why is it so surprising? 05AB1E is a great golfing language
@Mr.Xcoder umm...the message says that jelly beats 05ab1e on string-based challenge borking general relativity or something
not vice-versa

@cairdcoinheringaahing Why did you just post+unsandbox and then delete this?
@HyperNeutrino What was the challenge
Minecraft Crafting Table challenge
Do you guys want a link to my Twitter?
17:56
This has +3/-3, the people here don't really like git :P
I created a repository for Cthulhu
ok good it's number manipulation
because I was going to make a golflang sometime for list manipulation and it would suck if you did that too :P
animating this gif (or something similar) could be a nice challenge
that is cool :o
@HyperNeutrino I will try to make it good for number manipulation and sequences challenges, but aside that, it will holefully be good enough to be 3 times the size of a Jelly program :P
lol :P
For simpler challenges, Anyfix usually wasn't any longer than Jelly because the Jelly programs (or some permutation of them) would work in Anyfix too :P
17:59
@HyperNeutrino VTC your language as a dupe, then (Joke) :P
it is practically a dupe though :P
I mean, half of the atoms are identical
the other half don't exist
I will add the dictionary of commands soon
えぐえぐえぐえぐえぐえぐえぐえぐ -> Eiffel Tower deeply squealing
uh what?
@HyperNeutrino Google Translate "egu" repeatedly
lol
18:02
><
@totallyhuman yep.. all answers are using my regex :p
In golfing languages, what are arithmetic operators, +, -, etc.? Functions (dyads), Atoms...?
I guess they're functions, but I want to make sure
Anyone?
Forget it...
In Carrot I call them operators
there sure could be many answers, for example if the language is stack based or not
in SOGL almost everything (except newlines) is a function
I'll make them functions anyway.
18:07
"operators" because they operate on the stack...
> In golfing languages
There's no single answer. Golfing languages are as diverse as any other kind.
also ∧, in Jelly, operators bind to atoms (correct me if I'm wrong) while in Carrot they are just completely ordinary
@Dennis What are they in jelly, for instance, dyads?
@Dennis True
18:09
@Mr.Xcoder Yes. Everything is a link (function) in Jelly, even literals.
@Dennis I guess that's why Jelly is that concise.
When you write 0, you essentially get lambda: 0.
Soup, hot soup, to the finish line, food, sausages, sausages, apocalypse
Totally broke Google Translate
@Dennis I know, I have your Jelly repository open.
I started with a bunch of egu
Then I translated it through about 10 different languages
18:12
@Dennis Mind if I borrow your attrdict() structure class and the arity-based style?
Not at all. (attrdict isn't original anyway.)
@Dennis Thanks :p
My proposed challenge seems to be getting some praise
@ckjbgames The Croma one?
@Mr.Xcoder yes
4 upvotes already!
@DJMcMayhem Hi
My Twitter: twitter.com/ckjbgames
18:17
I have an operator idea: ± for Subtraction, but taking the absolute value (e.g. ±5 7 = 2, note that I used prefix notation). What do you think?
so essentially absolute difference
@HyperNeutrino Yes
I know it's a in Pyth
@Mr.Xcoder Cool. It could have more uses if given more or less than 2 inputs.
Hm. That's an interesting idea.
@ckjbgames Hi. I'm not here right now
18:18
It's a with a dot over it in Jelly (if I remember correctly)
@DJMcMayhem hi
Nope, it's a dot under it lol
@ckjbgames Not really, because it would add bytes for handling the unbounded arity
Another idea for ± is for 5±2 -> [3, 7]
@PhiNotPi That's even better
18:19
@PhiNotPi I already have an operator for that: #
@Mr.Xcoder do the new challenge in Pyth?
So if you write out the quadratic formula, for example, it gives both answers.
@PhiNotPi But it does not create a list, it creates a tuples
Here's a tip to keep in mind as well:
Jul 6 at 18:43, by TwiNight
I think 2 important philosophies of golfing language design are minimize error states and reasonable defaults
@LeakyNun What new challenge?
this one?

@LeakyNun I have no clue how to solve it in Python, and it would get worse in Pyth... I'll give it a try though
just hardcode it in python lol
18:21
But not right now, I'm trying to commit something to Cthulhu.
well too late Python is taken already
Q: Should I swap the usage of ± and #
@HyperNeutrino Who said that?
hckin hck
Ah, Uriel did
accidentally turned off my computer
18:23
@HyperNeutrino Ninja'd
at least you didn't accidentally to sudo rm -rf / --no-preseve-root

@HyperNeutrino That is the worst idea I have heard in human history
Make # for absolute dif and ± for the two-solution tuple?
18:24
how about alias cat=rm
@Mr.Xcoder yes
@Mr.Xcoder +1
@ckjbgames Done, thanks
@HyperNeutrino also awful, but not nearly as bad
@Mr.Xcoder link me to the repo

@Mr.Xcoder Thanks
There's nothing yet
I am working on the command dictionary
Starred the repo
Danke:)
@Mr.Xcoder Will you make another branch named something like "tmp" and upload what you have so far?
@ckjbgames Will do soon
18:27
@Mr.Xcoder k
@Mr.Xcoder Also, could you add me as a contributor so that I can write the repo wiki?
@ckjbgames Will do soon
@Mr.Xcoder yes
What's your name on Github @ckjbgames ?
@Mr.Xcoder It's ckjbgames :)
@cairdcoinheringaahing hi
@HyperNeutrino I was going to post it but I had to go watch a game of cricket (still there) so I'll post it when I get home

@ckjbgames Please accept my collaborator request
@Mr.Xcoder Doing that
@Mr.Xcoder Accepted
@cairdcoinheringaahing are you gonna do anything with the minecraft crafting challenge?
I'm writing the wiki homepage. How should I describe the language?
my sister did that
my sister did that too
2 messages moved to Trashcan
@ckjbgames then have your sister go away? I highly doubt that that can happen more than twice.
18:46
What sign should I use for ==?
@ThomasWard she actually did
@ThomasWard she pinned me down in front of my computer
@cair
@cairdcoinheringaahing hi
@dzaima I'm gonna post it when I get to a computer.
oops wrong window o.O
Please vote, It is important for Cthulhu.
ah okay. Talking about it, the scoring system seems pretty bad now that I think about it - you have 4900 bytes to implement 70 recipes before you go negative
18:51
I see the option "Other (Ping me)". Where is the ping?
@Mr.Xcoder why not just =? or what does that do (^ here and V +1)
≈ seems like the only reasonable of the options

@dzaima I want to avoid that. I think I'll use it for assignment
what golfing language has assignment
18:52
@dzaima Pyth
@NewMainPosts Why though?
@dzaima GolfScript, CJam, Convex...
What's it for? assigning a value to a variable?
I don't think Jelly's register counts.
@dzaima Yes, like in a=1
@dzaima Or naming a function.
18:54
@Mr.Xcoder Use the plain = sign. You can use for assignment
Cool?
@Dennis so does it count as a duplicate of my answer?
@ckjbgames Not a chance, sorry
@Mr.Xcoder What could be used instead?
I cannot type it with my Mac keyboard and I don't wanna be annoyed by that
What's the closest thing that you can type?
18:55
I'd personally have a limited amount of variables/functions and 1-byte reads/assigns
, §, ˘
Come on, I have 1 vote for each of them I cannot make a decision based on that
I'll just use what I like most,
Hold on, I'll add a second vote, for e
@LeakyNun 1. Duplicate answers are allowed. 2. If you prefer to FGITW the next language instead of at least trying to golf your first answer, I won't give you golfing suggestions.
10
@JanDvorak Why e?
to even out the votes
18:57
≈ is perfect.
@ckjbgames I think that too
@Mr.Xcoder Do that then
i did it
@Dennis How do you know I haven't tried to golf my first answer?
@Mr.Xcoder nice

19:04
@ckjbgames It is
@Mr.Xcoder cool
@LeakyNun Did you? The opportunity to golf 6,9,20 seems hard to miss...
@Mr.Xcoder
@Adám I cannot type that either with my mac keyboard, but I think I'll use for something else. Thanks for the suggestion!
I will use for equality checking
@Mr.Xcoder Why can't yo use =?
19:08
Hello
@Mr.Xcoder Seems decidedly *un-*equal to me
@Adám Because I'll use that for assignement
@Mr.Xcoder But you could use something else for assignment and use the obvious symbol for equality.
@Mr.Xcoder Can we have a list of typable symbols?

@Adám k
@Mr.Xcoder cool
@Dennis forgot to ask. What was wrong with TIO?
@Mr.Xcoder Which side of the assignment is the name and which is the value?
19:11
@Adám a=1 in Python will be the equivalent of =a 1 in Cthulhu
@Christopher Could you be more specific?
@Adám Prefix notation
@Dennis Probably the error with Cannot establish / maintain a connection with the server
@Mr.Xcoder Then I think § is a good choice for assignment, as in the statement of a rule.
@Dennis does it count as a golfing attempt now?
@Adám That might be a viable option.
@LeakyNun Uuugh: “-Œ¦‘ị@<

@Dennis Yeah xcoder said it. The server connection
@LeakyNun ị“-Œ¦‘<
@Christopher When? Now?
Just posted my question
@Dennis yesterday. I pinged you and you said you fixed it :P
@Dennis thanks
New Main Posts should post it in a moment
19:15
It works now afaik
@Christopher Dramatic traffic increase. TIO got mentioned on Hack News.
who voted to close my question
@Dennis That might be a good thing though
Not saying it isn't, just that TIO wasn't prepared for the sudden traffic spike.
19:19
@ckjbgames I didn't VTC, but adding two images and the result of them (like a test case) would be nice.
@Mr.Xcoder don't know how to do that

I need a test case
Or should I just use Wikipedia's
19:27
Check out Cthulhu again.
I have added a very tiny bit of the command dictionary
What do you guys think ^^^^ ?
Could someone provide a test case for my new question?
Grab Wikipedia's
@Mr.Xcoder I need one with a background color of #00FF00
19:30
Sorry, can't help
@Mr.Xcoder ok
@dzaima You are a lifesaver.
@Dennis alright, my Jelly program was wrong, now my program is 12 bytes. Do you have any golfing suggestion?
Who else thinks that is a great choice for sqrt?
19:35
@Mr.Xcoder yes
it should be the generic root
The empty program should be able to do a lot of stuff depending on the number of inputs
@JanDvorak Thought about that, but I have to implement it myself, because math does not have a built-in...
@Mr.Xcoder I have an idea for letting a builtin in Cthulu take a variable number of arguments (but less than its arity)
@ckjbgames hello world, primality testing and addition for 0, 1 and 2 inputs
19:38
@ckjbgames Nope.
@ckjbgames Adding a ) after it?
It just looks like it every time I open chrome
@Mr.Xcoder good idea. For example, the square root function, without a parentheses, is a square root. But, with a paren, it calculates the nth root of all the arguments added together except for the first one, (n).
@ckjbgames I'll make a generic root anyway, and I'll use this lambda: lambda a,b: a ** (1/b).
@Mr.Xcoder sounds good
19:41
And I'll use for square root
@Mr.Xcoder Maybe adding a paren would make it a normal square root
@Mr.Xcoder Just add a generic root; a specific square root won't be needed
@ckjbgames Of course I'll need a square root, because Cthulhu is (will be) a recreational programming language designed for code golf and number-manipulation
@Mr.Xcoder ok you're right
+4 in the Sandbox, 0 on Main :(
@Mr.Xcoder :(
19:43
@NewMainPosts wonder how long I'll have to wait until the 15 byte MATL answer
I gave it an upvote for encouragement
@Dennis ahh makes sense XD
If I made a golfing language would anyone use it?
Well more of a eso-lang
@Christopher :)
I added test cases to the question!
Thank you so much @dzaima!
And I removed my CV
@ckjbgames Wow, that's awesome :)
