// A class that contains a 2D angle as a pair of sine + cosine values.
// Sometimes, this approach saves substantial CPU time that would be wasted running these trigonometry functions.

Draw an L-System with Python's turtle graphics library, where the L-System is defined with a turning angle (d) a line length (l) and an axiom in the using the characters 'F', 'f', '+', and '-' to indicate rules. You can also iterate the axiom for fractal like patterns.
#!/usr/bin/env python
import turtle
D = 90
L = 10
def iterate(axiom, num=0, initator='F'):

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
