Short answer - de facto limit of 2000 characters
If you keep URLs under 2000 characters, they'll work in virtually any combination of client and server software.
Longer answer - first, the standards...

awk, 10 bytes
Input is expected on STDIN, one number per line.
++a[$1]%$1
Explanation
Keeps a counter for each number in an associative array, prints only if the counter value modulo n is not zero. Printing is implicit. Long version:
++a[$1]%$1{print $0}
ASCII Box rendering code-golf
Task
Your task is to write a program that will output ASCII boxes at the locations specified by the input.
Input
You will be given a list of numbers. The format here is a bit flexible, in that you can use any deliminator you want (e.g. 1,2,3,4, 1 2 3 4, [1,2,3,4]...
Cops and robbers, reveal as much as you dare
The cops challenge is to write a code that outputs exactly 20 printable ASCII characters. The objective of the challenge is to write a code that can’t be cracked, while revealing as many characters as you dare. The winner will be the submission with t...
Clock is an interesting card game, as it requires no skill. It is a single player game, and the same card configuration always leads to a win or a loss. In this challenge, you need to figure out whether a given card configuration wins or loses. You can play the game here.

Parentheses, brackets, and braces, oh my!
code-golf
If you have a string consisting only of the six characters ()[]{}, we say that it's balanced iff we can match all of the parentheses, all of the brackets, and all of the braces, such that none of the matches create overlaps.
good: ([{}({}[])(...
Irrational numbers are numbers that cannot be expressed as a ratio of two integers. But they can also be described as numbers that cannot be expressed as a recurring sequence of decimal places.
Let's define an irrational recursion as a call stack inspected after infinitely many calls that cannot...
Semaphore Decoder
You are to write a program which can decode ASCII semaphores. Each semaphore fits in a 3x2 grid, with the flagger's head represented by a o (which is always in the upper middle square), and his flags represented by _ | / \. Each block is separated by one blank column. Text m...

In my previous challenge, I
drew the first diagram mostly by hand (with the help of vim's visual block
mode). But surely there must be a better way...
Given an input of two dimensions, a width and a height, output a hexagonal grid
with those dimensions in ASCII art.
Here's the diagram referen...
Transpose quine
In this quine variant, your program must output its source code transposed across the diagonal from the top left to the bottom right. For example:
your code

c
o l
d i
