This is my blog, driven by Jekyll. Nothing particularly special here, unless you count the Gist tag (with caching) I added. To include a Gist, use the tag like so:
{% gist gist-number file-name %}
It will write the Gist embed JavaScript code, and also download the raw code from GitHub and display it inside a <noscript> block for RSS readers and browsers with JavaScript disabled. The contents of the Gists are cached in _gist_cache for subsequent builds, and can be cleared with rake cache:clear. For more details on the tag, check out the blog post all about it.
