A Brainfuck derivative Let's define a simple Brainfuck-like programming language. It has a two-directional tape of cells, and each cell holds one bit. All bits are initially 0. There is a moving head on the tape, initially at position 0. A program is a string over the characters <>01!, executed ...

A sample of a custom color scheme (like below) defined in .Xresources is often a good thing to have access to when editing said scheme or using the colors elsewhere in your system. The challenge is to color each definition's hex code with its respective color (e.g. black/color0 is defined as #00...

How acceptable is it to base challenges off of pre-existing challenges? I saw the challenge for Your Own Pet Ascii Snake and had a thought about making the output look more 'snakelike' by printing the characters |,\,/, and optionally ( and ) instead of always using the + character. Here's how it...

There's already a comprehensive list of tips for python here, so what I'm asking for are tips that specifically apply to using the numpy, scipy or pylab libraries. These can be either ways to shorten code already using numpy, or ways to shorten common python operations by using these libraries...

Grouping takes a list and splits it into new lists of equal adjacent elements. For example [1,1,2,1,1] -> [[1,1],[2],[1,1]] If you then take the length of these groups you get a new list of integers [1,1,2,1,1] -> [2,1,2] Your task is to write a program that takes a list of positive intege...
