@quartata Udioica has really pushed to expand the valid forms of input. I've seen him take input typed, in registers and in buffers. I'm not sure if those are all valid, but nobody's challenged him
An emirp is a non-palindromic prime which, when reversed, is also prime.
The list of base 10 emirps can be found on OEIS. The first six are:
13, 17, 31, 37, 71, 73
However, due to the reversal rule, emirps are different in each base. For example, the first six binary emirps are:
Bin | ...
@WheatWizard I'm not gonna say exactly what language I'm using or how I'm taking input, but since it's not really clear if pre defining registers in vim is allowed, I'm not doing that

I really understand now how the torus is the cross product of two circles, so to speak.
@Maltysen Life and other projects. :P
Seriously though, I used Spacewar! as a major component of my response to the code test I've been working on over the past several days, and last night, I had the idea of spawning missiles for a very brief time over the entire space so you get to see the flow, as opposed to a typical static force field diagram.
Anyone a pro at brainf***? I'm wondering if there's an easy way to extend the x=x*y algorithm to be x=x*y*z without just doing the same thing twice (if it'd be shorter).
@Rainbolt I think the challenge should really just have been to take a number as input then output the same as he was doing. The string as input just makes the challenge I/O more complicated.
Is this a safe refactor, if we assume that TableB.Id is not nullable?
SELECT * FROM TableA a LEFT JOIN TableB b ON b.Name = a.Name WHERE b.Id IS NOT NULL => SELECT * FROM TableA a JOIN TableB b ON b.Name = a.Name
I'm trying to understand why someone would use a left join where the right side of the join is not null. The venn diagram is telling me that it just becomes an inner join at that point.
Let's find the shortest quine in each language!
But wait, we aren't just looking for any quine. We are looking for non-repetitive quines.
This quine is very repetitive:
main(){char*A="main(){char*A=%c%s%c;printf(A,34,A,34);}";printf(A,34,A,34);}
This text appears in the program's source twice...
I almost opened up SQL Sentry Plan Explorer and pressed the "Anonymize" button, but I decided to put some effort into it and I anonymized the table names myself ;)
@betseg I'll go to anitkabir, and well, I learned that grandmother is actually coming all the way from tekirdag just to go to anitkabir, so I'll leave around 8-9am.
I need to find the most uniform non-occurring color of an image. I.e. if a=RGB(1,245,78) and b=(250,247,255) are both not in the image, b is the output, since it's the most "uniform" (in search for a better word). I know I can just pull all non-occurring colors and score them sequentially, but that's pretty inefficient. The only faster way I could come up with is GA. Is there a less complex algorithm to solve this?
@El'endiaStarman yes =) too bad you know too much about math: you probably already get that I can find out your whole polynomial by just asking for two evaluations:)

Haha. Someone just responded to an email with "That's a dumb question. [...]" and they obviously meant "That's not a dumb question. [...]" I didn't even notice that the word was missing until they facepalmed and then bolted down the hallway towards the other person's office.
A cruise control has 3 different options to move the handle to set the speed you want to drive with.
Towards you: Adds 1 speed.
Upwards: Increases speed to the next multiple of 10 (e.g. 20-->30, 32-->40)
Downwards: Decreases speed to the next multiple of 10 (e.g. 20-->10, 32-->30)

@flawr If this is the challenge in the sandbox, I think he's specifically looking for a balance point. Which means, that's where you put your pivot (which doesn't necessarily have to be there)
Unless, he's trying to name the thing you put there, in which case, sure!
I had to learn Perl in three hours using a book to solve a challenge with my team, and I was the typist. Constant "You forgot the dollar sign. You forgot the dollar sign. You forgot the dollar sign."
@Maltysen Do you dislike them because of the extra work and hassle that comes with them during the "let's try this and see if it works" phase of coding?
@El'endiaStarman that, and I don't think that they are necessary (except obviously for low level stuff like c) even for big projects if you have proper unit testing
@NathanMerrill but because of python's explicit is better than implicit, returning a string will throw an error somewhere else that is easily traceable
e.g. C#, it uses inferred types at compile time unless you explicitly specify it's an object. VS catches the errors at write time so it works perfectly fine when compiling.
@TuxCopter what you should do, is build each of your esolangs on top of the other. Aka, your next esolang should compile in to (Sigil) by listing the char codes of each of the characters, then take the absolute difference of each digit
@DrMcMoylex "The book is a promising reference concept, but the execution is somewhat sloppy. Whatever generator they used was not fully tested. The bulk of each page seems random enough. However at the lower left and lower right of alternate pages, the number is found to increment directly."
