Built by Andrew Page, "uber" is an unofficial Ruby wrapper for the Uber API. Using "uber," Ruby developers can integrate the power of the Uber API into 3rd party Ruby applications. Calls to the Uber API can be made to request information on available car types, driver location expressed in geo-coordinates, time estimates, estimated prices (including currency conversion when applicable), as well as user account history and activity.
Developers working with Google's next generation of its popular mapping API (our Google Maps API Profile) will be pleased to learn that some new features have been added to the API. Since its initial release a little less than a year ago, v3 of the Google Maps API has steadily been growing in terms of features and functionality. The latest addition of features are three new "layer classes" that make it dead simple to add KML (or GeoRSS), traffic, or bike routes as overlays on a Google Map.
Factual recently announced a new SDK that enables third party apps and services to pull location data from its massive database and trigger certain actions in response to data points like location, environment, movement and more. The SDK is easily used through the Garage Web UI.
