CMQ (inspired by a couple of recent events for me): A challenge poster accepts your answer. You notice the reputation change. What's your reaction?

@cairdcoinheringaahing heck yeah very cool get gamed on nerds

caird coinheringaahing

Wow, why does lyxal's answer not surprise me? :P

@DLosc How goes the blog post write up?

@Bubbler Given the post about Glenn Randers-Pehrson, a Rest In Piece post might very well be on topic for meta

Had a horrifying moment we’re I was writing in my esolang and realised that I had no support for JSON, but needed to parse it anyway

“Do I implement a JSON library in the language itself, and use C#’s built in library, or do I write a JSON library in the language itself…”

Huỳnh Trần Khanh

@ATaco i think it's time to implement a simple recursive descent parser lol, i think there are a lot of implementations on the internet and they are decently simple...

but implementing it in an esolang? difficult, but doable

Chose to implement a parser as my solution. Given the language is designed with practicality in mind, it wasn’t too hard

I was impressed with how simply JSON is defined, nothing like parsing XML

JSON is pretty clean grammar-wise

XML has... no grammar at all

Trying to parse XML is liable to summon Z̴̠̮̓ą̴̻͈̇l̴̘̑ǧ̷̦͊ö̶̟̣͖́̓͘

just run it through an XSLT stylesheet that formats it nicely /s

So...a church near my house likes to put the topic of the sermon for the next week on a sign outside. I know they have a limited number of those little letter tiles they can fit on the sign, but "eternal peace next sunday" could really use some rewording.

lol

4:33 AM

Y'all ever just used an autoclicker to be a cookie clicker tryhard?

dont they come with the game

@lyxal didnt code bullet do that?

@thejonymyster No no I mean an external autoclicker

Like an overlay that taps once every 10ms

ik im just saying it seems redundant

nah i just typed stuff into the console lol

4:34 AM

@PyGamer0 idk

@hyper-neutrino now tell me how tf imma type stuff into a console on the mobile app

skill

i wouldn't be able to tell you how to autoclick on mobile either

@hyper-neutrino adb?

How to autoclick on a mobile app: run it on bluestacks and run any autoclicker on your pc

There's an app for that

No rooted or anything?

why you think people use autoclickers: they want to hack and win
why they actually use autoclickers: they don't want carpel tunneling

@Bubbler Unrooted, download from the play store

since when did bedwars have eggs, or is this not hypixel

( I mean bed)

(Used to playing eggwars)

@emanresuA 3 beds

i think

maybe 2

Wdym?

@emanresuA idk it was like 4 months ago

Q: Pythagorean triples given the hypotenuse

Definition (from Wikipedia) A Pythagorean triple consists of three positive integers a, b, and c, such that a² + b² = c². The typical example of a Pythagorean triple is (3,4,5): 3² + 4² = 9 + 16 = 25 which is 5² Task: Given an integer number c, write a program or function that returns the list of...

Huỳnh Trần Khanh

10:36 AM

@pxeger hmm i think it's grammatical actually. "collectives" here is a name and a singular verb can follow that name

it may technically be, but it looks stupid nonetheless and would make much more sense to be pluralised

"What is Stack Overflow Collectives" might be better but even that sounds wrong to me

Huỳnh Trần Khanh

yeah

oh dear, it seems that stack exchange sometimes blocks vpns... so sometimes I can't send messages with my vpn on

I'm convinced that stack exchange is short on engineering resources now

It was a somewhat difficult test, my guess is I'll get a 90

Luckily there's a thing you can do for 10 points extra credit on it

whats the thing

in case i have to take the test

Redwolf Programs

Not sure, I haven't checked yet

But I know it exists. Once I open the box I can find out if it's alive or dead but it's both at once until then.

incroyabl'

i was never good at history. correct me if im wrong, but you really just have to memorize everything for tests, right?

@thejonymyster yes

with math you learn a skill / system, but history is just a sequence of events

math just being a rando example

2:29 PM

@thejonymyster i just try to memorize everything

in math or history?

in history

caird coinheringaahing

The problem with history is that you know the outcome before you even learn it: everyone dies at the end

yea, which sucks if you (general) dont have a good memory

how would i memorize in math lol

2:30 PM

originally it was a dupe by accident, so i flipped the challenge backways

Redwolf Programs

That looks like a cool challenge!

caird coinheringaahing

Although it's recommended to use something like [Any feedback?](link) rather than just the raw link, to avoid large one-boxing (like ^^) :P

Redwolf Programs

I usually do Any feedback on [challenge name](link)?, which has the advantages of both

fixed, still had edit time

oh oops

well, next time

Redwolf Programs

It doesn't really matter what format you use, no worries :p

caird coinheringaahing

@thejonymyster I'd suggest using something other than FALSE in the test cases, as I thought that was the actual output, rather than indicating a falsey value

Maybe 0?

Redwolf Programs

Or [falsy]

ah, good idea

2:41 PM

CMQ: What should the function composition of a unary function and 2 binary functions be?

hang on, gotta google "function composition"

caird coinheringaahing

@PyGamer0 Why are you composing those functions?

cause the answer is basically "whatever makes sense for your usage"

@cairdcoinheringaahing which is most useful in a general case

Redwolf Programs

I don't see any ways of doing it that immediately jump out as the best, though. Probably just figure out a consistent rule for ones with higher arities/numbers of functions and use that

Sort of like chaining rules

caird coinheringaahing

f(h(g(x, y)), h(g(x, y))) :P

The problem tbh is the second binary function

2:44 PM

agree, if it was just one, both orderings would make plenty of sense

Redwolf Programs

If it was one binary and two unary there'd be an obvious way to do it, but with two binary it's just kinda weird

caird coinheringaahing

1 unary and 1 binary have a couple of obvious approaches, but 1 unary, 2 binary is just weird

seems we all agree

Redwolf Programs

Maybe f(g(x, y), h(x)) or something?

i guess thats why the question is the way it is, or thered be no question

Redwolf Programs

2:44 PM

Or f(g(x, y), h(g(x, y)))

caird coinheringaahing

@PyGamer0 Have the second binary function distribute over the first, then apply the unary function

@cairdcoinheringaahing ?????????

caird coinheringaahing

h(f(x, g(y, z)) = h(f(g(x, y), g(x, z)))

CMC: Make a somewhat golf-oriented language with a two bit code page.

Brownie points if it's TC

jelly but each command is four characters

Redwolf Programs

lol

code page? im noob

Redwolf Programs

Basically you have four commands and they're two bits each

ah

Aaroneous Miller

3:35 PM

Why not just keep the normal 256 command codepage, but have each command be 2 bits instead of an entire byte? That seems much more efficient. /s

something something hq9+

caird coinheringaahing

3:51 PM

@RedwolfPrograms given the existence of OISCs, that should be fairly alright

@RedwolfPrograms JSFuck

Redwolf Programs

I'd question "somewhat golf oriented" given that even getting something to run at all is a few hundred bytes, and all constants are multiple bytes each :p

hyper-neutrino's language is the best solution

Redwolf Programs

I think I have a good one

I've got one (and I'm implementing it atm)

Redwolf Programs

4:00 PM

It'll be similar to Risky, but I'm thinking about changing up the way the adicities are determined

Instead of dividing in half, I'll do thirds

I've got 3 commands: push literal integer, repeat + eval, subtract, and I need one more

I've already got implicit input and output

Redwolf Programs

Interesting

Mine's just Risky but Riskier :p

And with better built-in choices

Not that I have many to work with :p

@RedwolfPrograms well theres your name

I know, I'll add a second stack

no, that's boring

Redwolf Programs

26 unique operators in two bits seems pretty good

4:03 PM

@pxeger comment

maybe reverse the stack?

maybe try doing something with the three you have

and then see what you wish you also had the most

@thejonymyster it's not gonna be golf oriented if that many of its programs are redundant

(I can't do maths today)

aw the math was the best part

it was wrong though

4:06 PM

rats

lol

4:32 PM

@RedwolfPrograms I definitely read that as "acidities"

make sure the pH of your program is balanced

@RedwolfPrograms I wonder if this paradigm could work.

@cairdcoinheringaahing Haven't worked on it yet--I've been up to my eyeballs in implementing a new language recently.

4:54 PM

@DLosc ooh shiny, what new language?

@pxeger A golfing Lisp with a Risky-inspired half-byte codepage

(Which will probably, like Risky, be somewhat golfy for some challenges but ultimately not be able to compete with Jelly et al)

given that Risky (4-bit codepage) can't really compete with Jelly (8-bit codepage), I propose:

Redwolf Programs

Finished implementing my idea

CMconjecture: golfing languages with codepages of more than 8 bits might be good

Redwolf Programs

Yes

That's guaranteed to be true

You can make more common operations use fewer bits than doing them by hand

E.g., with Risky, taking the cumulativ sum of an array takes quite a few operations. But in an 8-bit code page, you can afford to make that shorter.

At the cost of things like "factors of the sum of two numbers" which are built from a few simpler operations costing more

5:02 PM

but clearly, this wouldn't hold for a 100-bit code page

so there must be some optimum

Redwolf Programs

@pxeger That's just because it's impractically large though

well it's a balance of making longer programs shorter and making short programs too long

Redwolf Programs

@RedwolfPrograms For most of our challenges

@RedwolfPrograms well, and because all programs must now be at least 13 bytes

Redwolf Programs

For a really really complicated program it'd be much more optimal than 8-bit

5:03 PM

which means it loses to jelly by default 90% of the time

Redwolf Programs

But for anything usually lower than 100 bits it's a waste

i feel like somewhere around 9 to 10 might be optimal - a lot of languages have digraphs but don't end up using the full digraph space

so you could probably pack all of those commands into 9-10 bits

Redwolf Programs

10 bit it probably close to optimal, although if you're using weird operator sizes you might as well use huffman coding

Introducing Ultrarisky, a language with a 2-bit code page

It fits 26 overloads into that, so not bad

It uses a slightly different set of parsing rules from normal Risky

Anything with 3x+1 bytes it parsed into thirds, with the left third and the two right thirds being the arguments to a dyad in the center of those

Anything else has one to two monads before it

And a single operator is of course a nilad

with 4 digraph introducers, you have room for 1276 commands

Redwolf Programs

That's not how Riskylike parsing works

You get so many overloads because of the weird parsing rules, which you'd have to get rid of (or modify heavily) to add digraphs

5:11 PM

@pxeger @RedwolfPrograms this was for a "standard" 8-bit language (Jelly, Vyxal, etc.)

Redwolf Programs

Oh lol

I was gonna say "...but you definitely don't need that many" which would make my message make more sense but I got distracted lol

Redwolf Programs

Added comments under the gist for ultrarisky with documentation

so I reckon 9 bits is sufficient

Redwolf Programs

Sample program: I02I (subtraction)

5:13 PM

@RedwolfPrograms Meaning abcdefg would be ab c defg?

is there any way to concretely state the problem or is "golfiness" not quantifiable

Redwolf Programs

@DLosc Yes

 I  Input
  0 Add
 2  Negate
I   Input

Okay. I would phrase that as "with the left third and the right two-thirds being the arguments"

Redwolf Programs

Probably a better way to phrase it yeah

I was confused at first as to how one dyad could be in the center of three different sections

5:15 PM

triangular arrangement

Redwolf Programs

One issue with ultrarisky is that I had to drop the identity operators for golfiness, which might actually make some stuff basically impossible

And padding it to a whole number of bytes will change the meaning of the program

just typo'd git innnit and I have to say git is not very down with the kids

Redwolf Programs

E.g. a multiplication program would have to be 2II2I, which overflows into a second byte despite multiplication being just two bits

@pxeger Well, it's git, innit?

Redwolf Programs

I know Ultrarisky isn't turing complete, unfortunately, because it has no looping other than for and reduce over finite lists

If anyone can write a nontrivial and interesting program in ultrarisky I'll probably give them a bounty :p

5:24 PM

I feel like you could maybe replace negate with something more useful if you replaced add with subtract. Also not sure how useful square and abs are, since I think you could implement them using multiply and compare. But I haven't tried the language to see how the parsing affects things yet.

Redwolf Programs

Since golfiness was intended to be a concern, I wanted to avoid the mistake I'd made with Risky (having too many pretty specific operations, while generally useful stuff required reimplementing)

Fair

I was about to mention the lack of division and modulo operators, but then I realized you can use base conversion for those, right?

Redwolf Programs

Hopefully

I figured multiplication was more useful than division, and didn't have room for both

Redwolf Programs

5:57 PM

I just thought of a concept for a really awful esolang

1-bit codepage, lots of data types. 0 shifts the datatype by 1, 1 is an operation that depends on the data type

make sure to include a lot of novelty datatypes

i rlly like that idea btw :)

Q: Is This Scrabble Board Valid?

Background Scrabble is a word game in which players collaboratively build a board consisting of letter tiles that spell words. Each word must be connected to another word, and players gain points based on the letters they use and where they are placed. Words can be spelled either from left-to-rig...

code-golf decision-problem game

you just have like five different list types that you cycle through

and 20 integers

are trees covered in those five
