The script I wrote listens for updates from Google’s server and maintains a record of those updates. This coder’s script takes those updates and gets the actual changed files and maintains a local copy.
I can already think of a nice way to extend his update: write a script that presents that local cache of files as a single ZIP you can download. I suppose the reason they don’t offer that is because they want you to connect over SVN. But I think a lot of people might want to use the code but don’t want to bother checking it out, at least at first.
Anyway, moral of the story: open source is great.
How fresh is this thing on the sidebar? The six tiles are my most-listened-to artists of the week. The source data is courtesy of my last.fm music profile, which monitors the music I play in iTunes. The WordPress plugin is written by Gary Fenstamaker.
This is an example of the awesomeness of open source software and, in particular, the developers in the WordPress community.
(I should note that if you have a non-WordPress blog, you can still get the widget because the author also provides a standalone PHP version.)
