Generating a random stream of output when a specific output is required
For example, if a challenge requires you to output 4, you can't output an infinite stream of random digits, and say "4 is in there somewhere!" You must output 4, and no other number.
This is similar to this other loophole.
@El'endiaStarman How is that relevant? The user isn't saying "the output is there somewhere," they're #define-ing a bunch of stuff and using that to shorten code.
No, the issue is that the user is using a made-up "language" created after the challenge was created, that was "created" specifically for the challenge
Yeah, they need to split off the defines into another file and call that "the interpreter". Still icky, but I don't like those kind of "languages" much anyway.
It's pretty much a source-to-source compiler. If the user has a publicly-available compiler that takes input source file as they have it and spits out the appropriate executable, seems fine to me.

@TimmyD Then it was "created" specifically for that challenge, and then later reused for another challenge. It still postdates both challenges in question, though.
I believe that it shouldn't be a problem, as long as:
using the library does not violate the rules of the question
you are using a version that was released before the question was posted
that version of the library is freely available as of when you are posting your answer (please provide a li...

Thought: would a written set of steps describing exactly how to do source-to-source compilation count as a compiler for our standards?
@Mego Postdate, sure, but that's not something that prevents answering. Just that it (usually) prevents winning. Simply postdating a challenge isn't in itself illegal.
Isn't this pretty much how Pyth got its start?

They're also very poorly optimized

Enough that I'd say they aren't serious contenders

On the first challenge, it's ~70 bytes longer than the existing C answer (ignoring the dubious scoring). I wouldn't be surprised if a real C answer was similarly shorter on the second challenge.

General Rules
Okay, So the challenge is: Find biggest amount of primes, that are bigger than C's unsigned long long (18 446 744 073 709 551 615 or 2^64-1). Every language is allowed.
Scoring
For every prime you found you gain one point. Standard rules apply. Shortest code wins. Total score is...
Challenge:
Given a checkerboard, output the smallest amount of moves it would take (assuming black does not move at all) to king a red piece, if possible.
Rules:
Red's side will always be on the bottom, however their pieces may start in any row (even the king's row they need to get to). Black...

@Rainbolt Got Pluralsight renewed :) going to start watching soon - I feel like it will be very useful going forward as long as I understand it. I keep changing some things in one function and then not changing them in the other spot that I need to
@moderator would it be OK if I temporarily deleted the cake cutting contest koth challenge for 2/3 weeks? I want to run the challenge again at my school as an example programming competition and don't want anybody cheating
We're updating the jQuery version that Stack Overflow and Stack Exchange use from version 1.7.1 to 1.12.4 tomorrow (Tuesday, September 27) at 12pm Eastern/4pm UTC. jQuery is an infrastructure library, and we've been running on an old version for a while because it worked well. However, there are ...

A question which is not answerable with "Use jQuery" is not an appropriate question.
