Discover kigster/obstacle-avoiding-robot Open Source project

This gem implements a flexible time-ordered activity feeds commonly used within social networking applications. As events occur, they are pushed into the Feed and distributed to all users that need to see the event. Upon the user visiting their "feed page", a pre-populated ordered list of events is returned by the library.

Sym is a command line utility and a Ruby API that makes it trivial to encrypt and decrypt sensitive data. Unlike many other existing encryption tools, sym focuses on usability and streamlined interface (CLI), with the goal of making encryption easy and transparent. The result? There is no excuse for keeping your application secrets unencrypted :)
