The Cheela (from the book Dragon's Egg by Robert L. Forward) are creatures that live on the surface of a neutron star. Because they have twelve eyes, they naturally use a base-12 numbering system.
Among the Cheela, care of the hatchlings and education of the young are tasks carried out by the Ol...

Background: Ever since around March of 2014, Programming Puzzles & Code Golf and Code Review have had a friendly rivalry of who could graduate first (which has expanded to become a friendly rivalry in gen...
If you post a code-golf challenge after you designed a code-golfing language, it may be argued that you are somehow at an advantageous position. Knowing your language features may have influenced your challenge choice.
With this in mind, I posted a challenge today, answered in a language I had p...
This is (probably) happening, and it's annoying me, and there's quite a lot of backlash from the community.
If you read all of that post and the comments and the answers and the answers' comments (or, indeed, CTRL-F + code golf1), you will see niche sites like Code Golf and Code Review mentioned...
I've been working with base-36 recently and have never been satisfied with the usual answer to converting ints into base-36 strings. It looks a little imbalanced…
def to_base36(value):
if not isinstance(value, int):
raise TypeError("expected int, got %s: %r" % (value.__class__.__nam...
MATLAB xxx bytes
This is currently a work-in-progress using MATLABs built in symbolic integration capabilities. Currently the output format doesn't match the requirements, but it does qualify for the second -10% bonus.
If anyone wants to pitch in and suggest ways of correcting the output, or us...
Task
Given input N, generate and output an NxN grid where each row, column and the two diagonals contain the numbers 1 to N (or 0 to N−1 if that's easier).
Input
The input is a positive integer N. It represents the number of columns and rows in the grid. For this problem, you can assume N will...

The image is a scouter from Dragonball.
Let's map some strings to 2d space, fractal style. Your task is to compute a Hilbert curve and lay a string along it.
Task
The task is to take the single-line input string, and lay it out along a Hilbert curve big enough to contain it, but no bigger. Try to make the byte count as low as possi...
Meme: Absurd rationales for short code length
Originator: Unknown
Cultural Height: Always
Background: Why are we trying to golf our code down to the smallest number of bytes anyway? Many code-golf challenges will include a quip about why the situation requires a small program. These are often ...
Introduction
Santa has too many names to process, and needs your help! He needs you to write a program or a function, which outputs nice, naughty, very naughty or very very naughty. To determine how nice or naughty someone is, Santa had developed an algorithm:
Nice (division, math):
First of a...

Another new algorithm! Using Wikipedia's explicit definition. As usual, the byte count and a link for testing.

Here in California, we're in a drought so we need to know how much water we have left so we can conserve as much water as possible.
Because water is limited supply, your code will need to be as short as possible.
