There are two parts of writing code. Writing the code, and writing about the code. Often when writing about the code, you'll want to reference the code being written.
Github's Gists are useful for referencing snippets of code, offering the option to be embedded. The downfall to this option is that GitHub's Gists are embedded using inline synchronous script tags that will block the rendering of your page. Chris over at CSS-Tricks just did a great write-up on why this is less than ideal in his post Thinking Async, so I won't belabor the point here.
For the best reading experience possible, I want an asynchronous way to load GitHub Gists. And that is accomplished using the CoffeeScript below.
Right now this script finds all the anchor tags on the page that link to a gist and embeds them all. If there's ever a need, this could easily be wrapped into a jQuery plugin to give tighter control of what links are embedded. But for the present needs, this gets the job done.
