CMC: Write two expressions, one with a falsy value and one with a truthy value, but prefixing the expressions with + should make the first one have a truthy value and the second one have a falsy value
 
12:19 AM
There's probably some language where you could do this with a + that becomes a ++
 
+($a=-1) in perl

Q: Don't get banned from stack exchange!

tuskiomiI'm sure this is going to spark some controversy, but let's do a practical demonstration. The objective of this is simple, using the new code of conduct and no input, print out my pronouns ( "he/him", "he him" is also acceptable). Here's the challenge. This is a classical polyglot contest! ...

Is MyLang particularly less golfy than Carrot? (I need a lot of advice because MyLang is still in its extreme early development stages, I have only made 2 commits to the language.)
 
In a function submission that outputs a result by returning, is it OK to print some garbage to stdout?
 
@Bubbler Yeah, if stdout is not the way you give your result you can print garbage there

Great :)

Dannyu NDosThe Objective Build a random number generator whose range is \$[0,1) ∩ ℚ\$. What's the fuss? This RNG is weird. Its range is nowhere connected, but is dense in the interval!

I basically ran out of things to do on my TODO list to MyLang, therefore I am abandoning the language.
 
@A_ Goodbye, World!
 
A _
Oh no, Veskah is leaving this world!
 
Not yet (un)fortunately
 
A _
Or I need to reconsider what "world" means.
 
What is my function?
 
1:33 PM
As off topic as it is, we have many more relevant tags :/
 
@cairdcoinheringaahing They need a program that functions correctly, obviously.
 
A _
Functional programming is about making programs function without any problems.
 
Or the program has a function in it?
 
A _
A function is obviously a purpose of something that makes it work well.
Any program written has a function. Even the null program has a function: error in some languages, do nothing in other languages.
Yes, this challenge does need more specific tags.
 
@A_ No it doesn't, it'll be deleted within hours

Q: Make a haystack (with a needle)

AdmBorkBork(Essentially the inverse of Find the needle in the haystack) Given two tuples, (w, h) and (x, y), generate a haystack composed of a single random printable ASCII character of w width and h height with a needle made of a different random printable ASCII character at (x, y) when measured from the ...

@NewMainPosts canvas.... does not have any random builtins. ಠ___ಠ
 
@dzaima Does your APL answer to ^^ make sure that the needle is distinct from the hay? It seems quite short to do so
 
@cairdcoinheringaahing APL has dyadic ? for deal which makes sure results are distinct
 
@dzaima That's a nice feature :P Had to add 12 bytes to my answer for distinctness :/
 
3:51 PM
@A_ all languages that are not functional must be dysfunctional
 
4:13 PM
I'm not sure if it's a good sign or a bad sign that I've had so many deleted answers to my haystack challenge.

@newsandboxedposts Thank you

I assume that's supposed to be "3 integer points" instead?
 
Aye

@AdmBorkBork I feel like there's gotta be a better way of slicing a 1D array into columns and rows than a -join-replace'(.{$x})','\1`n'
 
@Veskah That was the shortest that mazzy and I (all mazzy) could come up with on the alphabet soup challenge.
 
Fair enough

CMC: output all positive integers which cannot be written as the sum of two other positive integers.
lol
 
I call them the "additive primes"
 
Better hurry and get it into OEIS
 
@Veskah -1 doesn't work if signed zero since 1+(+0) = 1 :p
