CMP: Proton's function composition (+) operator is currently backwards; that is, (a+b)(c) := b(a(c)). Should I fix it? I'd have to make a new Proton release version because old programs would break, but it doesn't exist anywhere other than PPCG yet.
@ASCII-only Nope. Once a language is up, taking it down could lead to link rot, and link rot is the greatest of all evils as far as Dennis is concerned.
CMC (this really means Chat Mega Challenge): Write a (playable, e.g., Tetris or Snake) game on a Casio scientific calculator (e.g., ASCII-only's fx-82AU). Must be playable. (not post on main because I don't know how popular is that model, but according to the previous poll it's not very popular; and also code-challenge without winning condition is often frowned upon, although actually solving the challenge is a winning condition, like the Tetris on GoL).
ooh a flak where brackets can face any of the 8 directions and the beginning of a bracket dictates where its position is during evaluation so a 2-d flak
I just notice that when I click at the "n new answer(s) to the question" when there are multiple pages of answer, the new answers will appear above the page selection bar. Meta.SE may be more suitable for that, anyway.
@HyperNeutrino Ok, so first of all, it's git commit -m "did stuff", and second of all, git add * ignores dotfiles, git add -A adds all files and git add . adds all files if you're in the repository root.
Hey Alex, ik you haven't been here in a while, but windows CMD just crashed on me, writing this to my clipboard:
[Window Title]
Windows Command Processor
[Main Instruction]
Windows Command Processor has stopped working
[Content]
Windows is checking for a solution to the problem...
[Cancel]
I accidentally pasted it into my console, and got this output:
C:\Users\Conor O'Brien
λ [Window Title]
'[Window' is not recognized as an internal or external command,
(long post bc I don't want to spread it over multiple messages)
speaking of which, does any brave soul wish to enter echo 3|@: into their windows cmd instance (if applicable)? It should replicate what happened above, sans alex
The challenge: Define x in such a way that the expression (x == x+2) would evaluate to true.
I tagged the question with C, but answers in other languages are welcome, as long as they're creative or highlight an interesting aspect of the language.
I intend to accept a C solution, but other langu...
So I just found out that you can get a hacktoberfest t-shirt by making 4 pull requests to your own repo. The only conditions are that the repo is public, and the PR isn't marked as spam. But if it's your own repo, there isn't anyone to mark your PRs as spam. Hmm.
I really like my CS teacher. The class I'm taking is actually the one after APCS, which she invented. The idea behind the class is basically "Here is spec, here's your group, you have a month to implement it."

I also tried an algorithm using additive partitions on a list, but it wasn't any shorter. This is a generator that produces an infinite stream of integers as output; the TIO link has a header to print the first ten thousand of them.

I was thinking of writing a codegolf challenge based on taking three strings: an example input (which would be an email address), an example output (which would be one of a small number options of formatting on the email), and an input email address.
The "examples" seems highly subjective. Although it is obvious to human, it is not obvious to computer. So you can restrict to certain permutation and case (uppercase, lowercase, titlecase, etc.) or make it code-challenge like this one.
@user202729 Yeah I was imagining just a few options: 1) the domain name (without tld), 2) everything before the @ unmodified, 3) before the @, split on the first . (if any), returning the name in Camel Case
Code-challenge is an interesting idea, I might have a think about that
iOS 11 has a bug that makes result of 1+2+3 to be 24. This is related to animation speed but anyway.
The task is to make 1 + 2 + 3 == 24. But only that. So you should provide function that allow adding any number of arguments and returns 24 when arguments are 1, 2 and 3 in any order.

For a submission with length n, number of riffle-shuffled program is n!÷(floor(n/2)!×ceil(n/2)!), which is, although exponential, still manageable for relatively small programs. So... the problem is slightly easier than the "Find the needle in the haystack" challenge, which is good enough.
About the You may only have 1 guess per answer part, I think that no guessing is involved here; an answer is either provably right or provably wrong. So incorrect answers, by site rule , will not be posted.
@cairdcoinheringaahing Character arrays reduces the need for duplicated functionality. E.g. You don't need a separate concatenation function for strings if you can use the general concatenation function for arrays.

Insertion sort counter
Calculate the number of insertions necessary to do an insertion sort of an input vector containing positive integers.
Example:
Input:
[5, 2, 1, 6, 3, 4]
Sorting:
[1, 5, 2, 6, 3, 4]
[1, 2, 5, 6, 3, 4]
[1, 2, 3, 5, 6, 4]
[1, 2, 3, 4, 5, 6]
Output: 4
