Some questions have a time limit, while others are all about the fastest code.
What general tips do you have to speed up PHP code?

The goal of this challenge is to take a simple 6 row by 6 column XML file (without the standard XML header) and parse it out so that the program can return the value of a cell given it's coordinates.
The entry with the shortest overall length by language and overall will be declared the w...
[This is a partner question to Calculate a probability exactly ]
This task is about writing code to compute a probability exactly and quickly. The output should be a precise probability written as a fraction in its most reduced form. That is it should never output 4/8 but rather 1/2.

I golf in TI-BASIC (the language that TI-83 and 84 series graphing calculators use), which is an uncommon language, and small even in proportion to the frequency of its use is the number of people in this community who know the details of the language. Therefore, good answers often go unrecognize...
I made this python code that generates 512 images with all the possibilities of combining a white or black pixel on a 3x3 grid. (python 2.7)

from PIL import Image
combinations = list(itertools.product([255, 0], repeat = 9))
img = Image.new('1', (3, 3), "white")
pixels = img.lo...
