Unfortunately // is interpreted as an invalid shell command and produces an error message, so we need to redirect that to /dev/null to get rid of it.

A good commit message looks like this:

Header line: explaining the commit in one line

Body of commit message is a few lines of text, explaining things
in more detail, possibly giving some background about the issue
being fixed, etc etc.

The body of the commit message can be several paragraphs, and
please do proper word-wrap and keep columns shorter than about

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

I was reading the gist @https://gist.github.com/2012250

I found the autovivification functionality of it pretty cool. If only I could have a parent reference...

Obviously this was not going to be a one-line tree. But that wasn't the goal

A simple variant:

from collections import defaultdict

    var objectToQueryString = function (a) {
        var prefix, s, add, name, r20, output;
        s = [];
        r20 = /%20/g;
        add = function (key, value) {
            // If value is a function, invoke it and return its value
            value = ( typeof value == 'function' ) ? value() : ( value == null ? "" : value );
            s[ s.length ] = encodeURIComponent(key) + "=" + encodeURIComponent(value);
        };
        if (a instanceof Array) {

This is a small collection of scripts showing how to use require.js. It's only one of several ways of setting up a require.js project, but it's enough to get started.

At its core, require.js is about three things:

1. Dependency management
2. Modularity
3. Dynamic script loading

The following files show how these are achieved.
