I just discovered a fun way to increment an integer by 1.
i+=!i!=+i
It's a palindrome (https://en.wikipedia.org/wiki/Palindrome)
Obviously it's very pointless code and you'd probably just confused people and they'd get mad and say "why not just i++;?".
But there is some novelty to it that mak...
Problem: given any input string that does not contain null bytes, determine whether or not the input string matches glob as defined below:

Our chatroom The Nineteenth Byte currently has 3 message feeds. For example, when there is a new meta post, it is automatically posted in chat.
Do we want to have new questions from the main page be a new feed?
El'endia Starman, a moderator, but not a PPCG moderator, has recently added an XKCD RSS feed to our chatroom The Nineteenth Byte, apparently based on the suggestion of one other user.
I am vehemently against this addition to our list of feeds for a number of reasons:
It was done non-democratic...

You should write a program or function which receives a string representing a chessboard with only pawns as input and outputs or returns whether any capture is possible on the board.
Input is in a FEN-like notation describing positions of white and black pawns with no other pieces present. You s...
Jozef Van Hove, better known as Pom, (b. Berchem, 16 November 1919 - 2 May 2014) was a Belgian comics writer and artist, mainly known for the comic strip Piet Pienter en Bert Bibber published in Gazet van Antwerpen. Pom was one of the best known Flemish comics authors of the 1950s. Between 1955 and 1995, 45 comic books were published of his newspaper comic strip. In 2010, a new album of Piet Pienter en Bert Bibber was created by Tom Bouden, with the collaboration of Luc Cromheecke, Dirk Stallaert, Steven Dupré, Martin Lodewijk, Marc Verhaegen, Willy Linthout, Jean-Pol, Steve Van Bael, Kim, Michael...
The Challenge
Given an input of integers, shuffle the integers (outputting the initial order and each subsequent shuffle) until the integers are in order. Your program must stop when the integers are in order (least to greatest or greatest to least).
Input
Input may be taken as either an arr...
Is solving Sudoku too hard? Even the brute force version? Here's a coding exercise that's a little easier. I hope. :-P

The hamburger joint maHburger has hired you to write a program for them.
It is simple: make an ASCII hamburger, using the key. Sounds simple right? Well these customers are super picky, but one thing is for sure, they do love onions.
Write a program that accepts the customer's orders, and print...
Your task is to create a program which takes a string, and if it contains any numbers, symbols or other non-letter characters, it throws an error. Else, it returns the original string. (The string may include whitespace)
("Letters" are a-z and A-Z)
Examples:
Input: My name is Joe
Output My na...

Yes, on PPCG a language is defined by its implementation.
In case your program is not portable you should specify the interpreter or compiler.
