How to stream the London 2012 Olympics

There have been several HOWTOs posted regarding streaming the 2012 Olympics using HTTP / SOCKS proxies via SSH and other similar methods. None of these actually work using the latest Flash on Mountain Lion (with Firefox, Chrome or Safari). Additionally, the third-party streaming sites don't provide BBC's amazing interface, which lets you quickly skip to individual competitors and events. However, setting up an OpenVPN server does work, with some tweaks. You'll get the exact same UX that people in England receive.

Get a Linode VM in the UK. The 512MB server for $20 works just fine. (If you want to use my referral link, go for it: http://bit.ly/OuzdVe)
Follow the standard OpenVPN installation documentation. (Basically, 'apt-get install openvpn' or 'yum install openvpn' and then follow these docs: http://openvpn.net/index.php/open-source/documentation/howto.html). For an OS X client, I prefer Viscosity: http://www.thesparklabs

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

Creating a Happy Git Environment on OS X

Step 1: Install Git

brew install git bash-completion

Configure things:

git config --global user.name "Your Name"

git config --global user.email "[email protected]"

New Machine

Here's what I do after I do a fresh install of Lion. Things are sorta grouped by type.

General Config

Run Software Update
Start downloading Xcode
Disable auto-bright and turn brightness all the way up
Enable mouse right click

#Stay Standalone

A short script to prevent internal links to a "webapp" added to iPhone home screen to open in Safari instead of navigating internally.

	//usage
	withAdvice.call(targetObject);

	//mixin augments target object with around, before and after methods
	//method is the base method, advice is the augmenting function
	withAdvice: function() {
	['before', 'after', 'around'].forEach(function(m) {
	this[m] = function(method, advice) {
	if (typeof this[method] == 'function') {
	return this[method] = fn[m](this[method], advice);
