I use Homebrew and wanted to install pip for mercurial.  Pip requires a homebrew-installed version of Python, which is fine and dandy; however, I noticed that webkit2png was broken after I installed Python with Homebrew (it was missing pyobjc libs, which comes with the OS X Python install by default).

This assumes that the current homebrewed version of Python is 2.7.1 and that homebrew is set up for /usr/local.  If that's not the case, you may have to change the minor version of setuptools (e.g. from 2.7 to 2.8) and change the PATH accordingly.

$ brew install python

Modify your PATH to include the path to Python's bin directory:

export PATH="/usr/local/Cellar/python/2.7.1/bin:/usr/local/bin:$PATH"

To reduce the need for "visual confirmation" tests:

• store the base-64 encoded data-uri of a reference png as a string
• copy the outerHTML of your test fixture into an SVG wrapper, prefixed with "data:image/svg+xml,"
• set the src of an image to the value of the SVG wrapper
• copy the image into a canvas context
• assert equality of canvas.context.toDataURL() and previously stored reference string

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 = git@github.com: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:

let defaults  = {},
    overrides = {};

function foo(bar, options) {
    // YUI
    options = Y.merge(defaults, options, overrides);
    
    // Underscore
    options = _.extend({}, defaults, options, overrides);

How to make faster scroll effects?

• Avoid too many reflows (the browser to recalculate everything)
• Use advanced CSS3 for graphic card rendering
• Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:
