some of Haskell's extensions are the literal cutting edge of programming language research
@DJMcMayhem Another button is "Where am I?"
and yet another is "Insert Cheesecake"
C++: A modern programming language scarred deeply by its past
it did pioneer a lot of what we think of today as normal programming languages
@dzaima code golf programs should terminate quickly; you would just terminate if it doesn't terminate before the original program terminates

@DJMcMayhem Apple recently released an update to AVFoundation that allows developers to detect if there is a cat or a dog in the frame when taking a picture. They're so behind the times lol

Your task, if you wish to accept it, is to write a program/function that outputs/returns its string input/argument. The tricky part is that if I reverse your source code, the output must be reversed too.
For simplicity, you...

@KrzysztofSzewczyk I think we actually had another user do that kind of thing a while ago. I didn't like it because that user was not giving other site users much chance to participate by locking down many popular languages.

CMC:code-challenge Given an integer, return that same integer using the shortest possible code you can. Your score is (x y) where x is your code length (lower is better) and y is the number of solutions of that length you can create (higher is better). E.g. if your shortest code is AB but AC and AD also work, then your score is (2 3) which is worse than (1 3) but better than (2 2).
@NieDzejkob characters in k have multiple meanings depending on the types of the arguments, . with a string is eval, with a dict it's values, with a fuction and list it's apply, with 4+ args it's amend at depth, etc
Well, the fact that eval on the empty string returns the identity function is irrelevant. What matters is how you got the function-value you could apply or assign to f.
I have an idea for a challenge: "I negate the source code, you negate the output". I go over every byte of a file and negate it and the output has to be negated (either logically ["2" -> "-2"] or 2's compliment [1 -> -2]).
@ngn what i was trying to do was give a simple example where the simplification leads to bad results (though really it misrepresents the result for any non-constant n or m), not establish/require any relation between the variables. (note that i know nothing about time complexities formally so what i'm saying may or may not make any sense)
@DJMcMayhem PPCG requires all answers to be counted in 8-bit bytes, so manipulating the bits of those should be 100% defined everywhere. certain decoders might not like the result but that's not the challenges problem
@dzaima Not necessarily. A language could have defined behavior for ASCII and undefined behavior for code-points 128-255 as long as it avoids those bytes
Also, for whatever reason I was thinking of reversing the bytes. Two's complement would for sure break ASCII and UTF-8, since both of those standards require the leading bit to be a 0

Not so long ago, I had an idea that I will try to formulate. The task is to build a computing system inside a figurative computing system. Four adjacent tetrahedral are a 1x1x1 matrix. This is enough to introduce n=2^(х-1) algorithms into it, where x is the number of vectors (faces). n=2^17 under...
Convert a string containing digits as words into an integer. For example "four two" -> 42.
Submissions can assume the input string is space-separated and all words are valid and lowercase.
Linear algebra problem (related to a previous question I've asked in here):
Given an arbitrary rectangular matrix M, is there a way to determine whether there exists a pair of vectors x and y with all-positive entries such that Mx=y?
