The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.
In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.
This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.
An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.
Everything is broken up by tag, but within each the selectors aren't particularly ordered.
I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A
A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:
-webkit-appearance:none;

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications
like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.
open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl
You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html
