@lyxal Thanks for asking, but it's ok to keep frozen more. I think I have decided to keep Atlas the same as it is but will be working on a new lang now that is somewhat similar

I was working on test cases for this Sandboxed challenge and found a really interesting algorithm that seems to work for constructing any number that can be expressed in closed form with no nested square roots :P

Been working on a proof that the method does indeed work for all such numbers, and so have been distracted from, y'know, actually posting the challenge :P

A: Sandbox for Proposed Challenges

Output the works of Shakespeare with the greatest probability We all know that a monkey hammering out random bytes will output the works of Shakespeare with some probability. This probability is extremely low. But what if the monkey would type out a computer program instead, and then we run the c...

Q: Shapes Biscuits - An Un-identical paradox

Puzzle I have a packet of Shapes biscuits. I would expect all of them to be identical, but alas, stacking all of the Shapes does not result in a perfect hexagonal prism. I'd like to find out what percentage of shapes are different from the rest. In a packet of Shapes, there are n Shapes in total....

Can you really call them biscuits tho?

Well, technically they are, but crackers is more accurate

Because they be savoury

Can this code python code be made iterative instead of recursive? math.stackexchange.com/a/4823095/1131135

@RydwolfPrograms I feel every time I come up with an interesting challenge someone reduces it to something trivial within 5 seconds

Simd

I think the answer is yes

@mousetail can you give an example?

@lyxal the UK and US have completely different meanings for the word biscuit

Simd

7:27 AM

I don't even think there is a British word for the US biscuit

Dannyu NDos

Uhh... scone?

Simd

@DannyuNDos I am not sure they are really the same

Would you have clotted cream and jam on a US biscuit?

google.com/…

Dannyu NDos

IIRC they're served with strawberry jam here in South Korean KFC?

Simd

That's great :)

@Neil mostly suggestions, there's two major things to fix

notably, ReflectOverlap is defined in terms of itself and › is described as being Less

and of course markdown ate the newlines

one tick, I'll fix the quote spacing

fixed

anyhow, hopefully that helps

I tried to give feedback as if I was writing feedback for my own reference guide

also, wow Charcoal has some questionable overload choices

questionable as in "goofy" or "funky"

also, where's the character for print?

i'm not seeing any character

think I've discovered another Area51 problem

Every time I try to click "log in" it goes to a "redirecting you to area 51" page

> you will be redirected automatically

very doubtful

oh huh

it was a userscript problem

@lyxal I think it's because there isn't one. If you put a literal in the code not as part of another command, it gets printed.

Good Afternoon, @Willtech looking for the rules of Code Golf

Ginger

hmm

@Willtech what do you mean?

Willtech

@Ginger Well I see each challenge, I searched for rules, what languages are acceptable, for example?

Ginger

you're looking for information on how to answer?

this may help you

as well as some of the other articles in the Help Center

Willtech

@Ginger Good work

Ginger

...thanks, I guess :p

@lyxal thanks, that's really helpful.

6:12 PM

@Simd @DannyuNDos this was discussed extensively on English SE when I asked about it. The general consensus seems to be that there is no term that a British person would readily understand, but "scone" is closest: english.stackexchange.com/questions/600828/…

Having jam on a US biscuit isn't unheard of, but it's not the most common way to serve them

Simd

6:29 PM

@Someone American ‘biscuits’ seems right

Definitely not scone

Or American-style biscuits

Q: Solve the word problem*

In this challenge you will receive a list of positive integers \$W\$ called a word, and a square symmetric matrix \$M\$. Your task is to determine if the word can be turned into the empty list by applying a series of valid moves. The valid moves are: If two consecutive values in the list are equ...

@lyxal my feedback to your feedback

RubenVerg

is there a list of common golflang features? want to write a tiny lang to golf in for fun, was curious what are the most common things to have in it

Adám

7:37 PM

@RubenVerg I'd look at the common features of Jelly, 05AB1E, and Vyxal, prioritising their 1-byte built-ins.

emanresu A

Or if you're going for minimalist probably nibbles

Adám

Another "minimalist" approach is simply the vocabulary of an array language.

Unrelated String

outside builtins, you can get real creative with how programs compose them, but you're always going to want to prioritize being able to tacitly compose them over conventional praclang constructs with variables

the basic choice, which still offers a lot of room to innovate, is to go stack-based

but you can also do chains or if your design motivates it even true prefix/suffix

Adám

Since you're already proficient in APL, maybe just inherit its syntax (more or less), with some carefully chosen built-ins to maximise golfiness?

Simd

7:56 PM

evening!

RubenVerg

@Adám the problem with stealing primitives from other languages is coming up with new glyphs for them :)

Adám

Why do you need new glyphs for them?

RubenVerg

hm, fair point

I suppose nobody would mind if I made my indices-where-truthy primitive a ⍸

though I think there's a fine line between "language with lots of things from APL" and "APL with easier to parse syntax"

Adám

It wouldn't be the first golflang to use APL glyphs.

Simd

9:14 PM

I think this place must be unique in the ratio of answers to votes

12 answers, three votes

mousetail

That's pretty common for easy challenges

Dannyu NDos

@NewPosts I thought that was about group theory.

Heck, too sadge word problem is undecidable in general.

Q: Output an image

Output: Any image output is accepted. This is code-golf, the shortest code that can accomplish the task ...

@Neil fair enough

I didn't realise map gets its function by evaluating a string as code

I would have thought it used a function literal

@RubenVerg there is

@Neil That can't be right, you should have a silver parsing badge by now

You have 404 score / 151 answers, and need 400 score / 80 answers

Neil

@lyxal it's not a function as such, it's just an expression, e.g. Map(q, Times(i, k))

@emanresuA I do, thus the "nobody else" and "let alone silver"

emanresu A

Ah. Looking at the top users page at least Arnauld, Martin Ender, Dennis, Jonathan Allan, ovs and Kevin Cruijssen should have bronze

Neil

@lyxal demo: Ｅθ×ικ

emanresu A

yeah

Neil

@emanresuA huh, I must have misclicked

(probably clicked on silver parsing again by mistake)

lyxal

11:05 PM

@Neil ohh so it's like a sort of a structure?

emanresu A

Either that or you interpreted this as a full list of everyone who recieved the badge

Neil

maybe, but I thought I double-checked for silver at least

@lyxal still not following. in my demo, q is the string Charcoal. Being iterable, Map evaluates Times(i, k) once for each character in the string, where i is the character and k is the index. This results in a list of strings, which prints by default

lyxal

At first i thought it required along the lines of Map(q, lambda x: x * k), but I realise it's more similar to a control-flow structure

Neil

a bit like And, which evaluates its RHS 0 or 1 times?

lyxal

11:44 PM

I think so
