"url_shortener" is a Ruby gem/library that wraps the Bit.ly API for Ruby applications. A implementation tutorial for the wrapper can be accessed from the GitBug repository. Though not directly supported by Bit.ly, the wrapper is endorsed for use on the Bit.ly developer site. The Bit.ly API allows developers to implement programmatic shortening, URL expansion, sharing, and tracking of links (URLs). Unique user-level and aggregate links can also be created to let users view complete, real-time traffic and referrer data, as well as location and metadata.
Taking pictures on your iPhone gives you a great deal of data embedded in to your photos. Location, camera type, exposure, even camera orientation. But what if you want more.

Google has released a new API for Fusion Tables, a Google Labs app that allows users to import, integrate, analyze, and visualize data in a variety of ways. The new API allows developers to programmatically perform a variety of tasks, including data import and export (more at our Google Fusion Tables API Profile). The API itself is integrated with several other Google APIs, including the Google Maps API and the Google Visualization API. In fact, developers can also leverage App Engine to easily develop data processing and analysis apps that easily integrate with various other Google APIs.
