Google Calendar Chrome Extension adds a button to your browser toolbar that displays a preview of your calendar while you're navigating. (works on any page). If you're on certain sites where it detects the presence of events, the icon changes to a green "+". Clicking that icon lets you add the event to your Google Calendar, and shows you a Map (if there's a location it could detect.) Supported sites include Facebook, Evite, and any site that uses the hCalendar microformat or derivative microformats such as hResume.
CCI:U Open Course Labs is a Django-based Web application that interfaces cloud-computing infrastructure such as Amazon EC2 and NexR iCube Cloud. More backends may be added. It provides the access to cloud infrastructure in the form of "course labs" where course staff in an academy can manage the allocated computing resources and assignments easily. Course labs can also be used as course homepages.
