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:

I like Rdio and linux. Rdio works great in a browser except for one thing: keyboard shortcuts!!!

When coding, I like to be able to play/pause my music quickly, meaning I don't want to switch windows. I figured out a way to do this:

Google Chrome --app

First, I made a file in my ~/bin called rdio that runs:

google-chrome --app=http://rdio.com

// The data
var items = document.getElementsByTagName('p');

// The old way
var arr = Array.prototype.slice.call(items);

// Pros:
// - Doesn't need a helper method that loops through stuff
//
// Cons:

Most active GitHub users (git.io/top)

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

Only first 1000 GitHub users according to the count of followers are taken. This is because of limitations of GitHub search. Sorting algo in pseudocode:

githubUsers
 .filter(user => user.followers > 1000)
