Someone's posting on all the function entries saying they're invalid; could you edit the question to make it more clear that functions returning the string are allowed? Right now it does sound like only programs are allowed
Write a (hic) quine
Your challenge is to write a hiccup-quine. A hiccup-quine is a program or function which, when run, follows these steps:
Generate a random integer n between 1 and 10, inclusive.
Wait n seconds.
Print the next n chars of your program's source code.
If there is code left to p...
What is the smallest number of characters you can restrict Python to and still have it be Turing complete?
For example, with Javascript, you can restrict it to six characters.
Note that "Turing complete" does not mean "all of Python". It just means that it is able to simulate any computation. ...
The task:
You have to input 2 numbers and output the results of several operations done with them.
Details:
Input 2 numbers, x and y.
Output x+y,
x*y,
x^y,
x-y,
y-x,
x/y and
y/x
Standard loopholes apply, the shortest code wins. Good luck!
@NathanMerrill No that's not it. I want a cheap random change to a long list so that eventually the probability of being at any list is equal
imagine I didn't care about the sortedness. Then you could just pick a random index i and a random value x from 1...p^2 and do L[i] = x, where L is the list
@NathanMerrill You get a problem with stuff like [1,2,3,4], where only the largest value can change. So really, you should select an index among those that can change.
I think you can still demonstrate that the distribution is not uniform. [1,2,3] can only be reached from a small set of lists whereas [2,3,4] can be reached from a lot more lists.
> A man owned a store called "This and That" and hired another man to make a sign for it. When it was finished, the owner inspected the work and discovered the spacing was wrong, so he said "The space between This and and and and and That is different. Please fix it."
@TimmyD It would have been more clear if you had put quotation marks before This and between This and and, and and and, and and and, and and and, and and and, and and That, and after That.
Monday, October 31st, is Halloween. And it got me thinking -- I wonder what other months have the last day of the month also be a Monday?

A positive integer in any convenient format representing a year, 10000 > y > 0.

Both programs have been tested locally with the same 8 byte file, so this is a proper polyglot.

@1000000000 I think you can get it if you get downvoted but then reach cap but then get un-downvoted, or something like that. I remember reading something similar on Mother Meta.
@TonHospel Your code is very impressive. i = 31 236749312694943744 (took 10.0781638622 seconds) i = 32 253599876468703232 (took 10.0682039261 seconds) i = 33 -2720941644516950016 (took 44.5673849583 seconds)
It's an interesting theory. Let's test it. One of you should downvote me, then 5 different people upvote, then the first person un downvotes so we can test it.
Cheat is a card game where you're trying to get rid of your hand. A turn looks something roughly like this:
Determine what card rank you have to play that turn. In most variants this is one rank higher than the previous turn.
Play 1-4 cards, face down. These don't have to match the valid rank. ...
@Lembik If I'm not mistaken, you could use strictly increasing lists instead of non-decreasing ones (since there's a bijection between the sets), and make one step by deleting a random list element, choosing a uniformly random new element that's different from the remaining ones, and insert it at the right position. That's O(p) instead of O(p log p), and I think the resulting graph is regular, so the invariant distribution is uniform.
Cheating Semiquine
Concept
Write a program that outputs code in its programming language. That code, when executed, must output the original program.
Rules
Since this is a cheating quine, you can read the original source code.
First output program must be in the same language as the origin...

@Mego indeed. btw, did you get the call from google yet?

@ConorO'Brien Sort of. I got the call, but it was to tell me that apparently the SVPs never got a copy of my professional references. So, I resent that file, and they'll meet again next week.
because there are only so many interesting alphabet challenges
Anonymous
@Downgoat Because the sequences aren't related other than the fact that they're sequences. The alphabet challenges can all be summed up as "print this string N times in X pattern". There is no Online Encyclopedia of Alphabet Patterns because such a thing would be uninteresting.
I honestly think its a rather clever idea. The fundamental "build a pattern" is an interesting challenge style, but historically, every time a good idea comes around, an explosion of challenges happens
that said, due to the ease of creating an alphabet challenge, it made the explosion even bigger
@HelkaHomba I've been recently working on a reduction form of ><>, and have concluded that each arrow can be represented with the mirrors / and \ and trampolines !.
You just got your brand new FPGA-based calculator.
It has a programmable chip, where you can input "rules" that the calculator has to follow. You could create a rule called "2 + 2 = 5", and then any other calculation would be based upon that rule.
