To Somebody: Don't do it. Someone else had already done it.
4:49 AM
-> "Somebody attempted to search for me, using their hands today lol"
phish -> fish

@H.PWiz that 28 is very similar to my 27 ;)
for Julia √big(5/4)+.5 also works for 36, as does MathConstants.φ

Q: !I!n!s!e!r!t! !b!e!t!w!e!e!n!

A__Posted from here. This challenge is highly "distilled" from this question. Special thanks to @Akababa! In this task, you should insert an exclamation mark at the start of the string and after every character. Rules There will always be a non-empty-string input. The input will not contain tab...

A: Sandbox for Proposed Challenges

A__Talk interpreter "Talk" is a baroquified accumulator-based language that is created in order to make it difficult to put on Try It Online. The "Talk" language has 4 commands: 00 If the accumulator is 0, set the accumulator to 0. 01 If the accumulator is 0, set the accumulator to 1. 10 If the a...

@A__ Phish basically means when somebody tries to get you to click on a malicious link
I was going to clarify it but forgot
3:02 PM
Basically, what happened is that I decided that maybe I had been wrong to dislike Roblox and decided to test it out again
I played a game called Phantom Forces
and basically, one person told me to contact him on Discord
I did; what could go wrong?
I went into a group chat with his friends
We were talking, and then one of his friends says "Are you into Youtube?"
I said yeah
He sent me a link to his "youtube channel"
Except it wasn't youtube.com
It was this really suspicious website with dashes in the domain
He blamed it on some tinyurl thing that would convert all links to a tinyurl link
I said to disable it.
And suprisingly, I got kicked out!
I contacted the original guy, and he said "that's weird." I explained that it was obviously malicious
He asked what phishing was, and I explained it
Now I am awaiting his next message

Q: Lazy brainfuck programmer

Krzysztof SzewczykBackground Joe is working on his new Brainfuck answer on Codegolf. The algorithm he's using to solve the challenge is a bit complicated, so Joe came up with idea of simplifying his Brainfuck notation to make programming easier and faster. The challenge Let's look at snippet written by Joe a mo...

Q: Why are there still a lot of issues for a Sandboxed post Sandboxed for a long time?

A__When I posted this to the Sandbox, I have waited for 21 days before I posted the challenge to main. However, there are still a lot of issues in that post, and someone had found a duplicate. Why are there still so many issues in a Sandboxed post when people would have found more issues in the ext...

I was hoping someone would mind having a look through this challenge proposal; I'm considering posting it in the next couple of days

@cairdcoinheringaahing suggestion: allow a list of ints as input
if we consider them "digits" in a mixed-radix system, that's the same as one big int
@ngn What do you mean list of ints? The input is a single integer
@cairdcoinheringaahing the problem is it requires >64 bits, so it might be worth allowing alternative representations
@ngn So what exactly do you mean by a list of ints? Can you give an example?
@cairdcoinheringaahing so, the group of rubik's cube configurations is a product of several independent smaller groups. we could solve the problem separately for them and the inputs could correspond to the smaller problems
a list of (bounded) inputs has a trivial mapping to a single integer
@ngn I'm not sure I fully understand, but I'll allow alternate input formats as long as they're clearly explained in the answer (I'll edit this in)
7:33 PM
real world example: the length-3 list hour:minute:second corresponds to a certain number of seconds since midnight, but in practice it's more convenient to use a list with 3 small numbers than 1 big number
@ngn Ah, that makes much more sense
@cairdcoinheringaahing another option: consider only configurations in which the central cubies are fixed (e.g. white always points up, blue to the right, etc). that would reduce the number of possible configurations by 24 and the big number would fit in 64 bits
7:59 PM
@ngn I'm not a massive fan of that, as it kinda takes away from the challenge. Keep in mind that it can work theoretically for every number, but is allowed to fail for numbers outside of a language's range
8:24 PM
@cairdcoinheringaahing sure, that works too
@cairdcoinheringaahing oh... but that big number (43252...) is already under the assumption that the centres are stationary
so, there's no factor of 24 to take out anyway
@ngn Yes, because the center square cannot be rotated out of where it starts, and rotating the entire cube isn't considered a 'move' as it doesn't affect its net
@cairdcoinheringaahing that might be worth mentioning in the challenge. currently it says "permutations that a Rubik's cube can be in"
@ngn Ok, I'll clear that up

Q: Write a radiaton-hardened irradiator

TheOnlyMrCatThe task is to write a radiation-hardened irradiator. What do I mean by that, exactly? An irradiator is a program that, when given a string as input, will output all possible versions of the string with one character removed. For example, given the input Hello, world!, the program should output:...
