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.
CI-Eye is a powerful continuous integration build radiator requiring no installation and almost no set-up. CI-Eye talks to many different CI servers through their REST APIs (so no plug-ins are required). Currently, support is offered for Hudson, Jenkins, and TeamCity. CI-Eye runs as a standalone Web application.
