The official Stormpath Ruby SDK by Stormpath calls the Stormpath REST API which provides developers with a user management infrastructure. Features include authentication, schema-less user data and social media login with Facebook and Google OAuth. It requires Ruby 1.9.3+.
Well over 600,000 developers participate in a topcoder community that not only allows them to expand their development skills, but also gives them access to projects where they can get paid for participating.
Solar VPS, cloud-based virtual private server provider, launched its first SolarSystem API. The API is included with a handful of new features Solar VPS unveiled with release of SolarSystem 2.0. The API allows users to integrate, automate, and manage VPS environments in a customized manner. For kicks, the Solar VPS team built a native app on top of the API, and had it up and running in less than a day.
