The Github API can sort by pushed time, no need to do it manually.
http://developer.github.com/v3/repos/#list-user-repositories
This is both more efficient, Github does the sorting, but it also
fixes a bug. Because the list of results are paginated, if you have
more than a page's worth of repositories it will only sort that page.
This results in a false view of what has been recently pushed.
For a good example, try my github account "schwern" with and
without this patch.
if you specify
github_user:
in you _config.yml and once you add asides/github.html to your sidebar
items, this plugin will fetch the specified users github repositories
and order them so the last pushed ones are shown first. Then it'll list
them in the side-bar, including a link and the repository description
The plugin will only list your own repositories, not forks, though this
might need to be configurable later
