Use this Perl module to access Docker's Remote API. Docker offers tools for sharing apps and repositories, and for developing applications across a distributed platform. See the project page for SDK installation instructions and code samples.
As announced on the Flickr Blog, Flickr has launched a new website for developers: Flickr Code. And besides announcing the new site they've both a) given interesting details on just how much API traffic they do each day (see below), and b) they announced they're open sourcing Flickr Uploadr, the cross-platform (Windows and OS X) desktop tool for uploading photos to Flickr.
