Eureka Streams

Eureka Streams is a free, open-source enterprise, social networking platform developed by Lockheed Martin. Activity streams and gadgets make up its core functionality. Content within Eureka Streams consists primarily of microblogs and internal and external web feeds. Users typically provide links to other content, such as wikis, blogs and shared documents housed in a content management system.

Technical architecture
Eureka Streams uses a shared nothing architecture. It uses Memcached, Apache Maven, PostgreSQL and Hibernate. It uses Shindig for OpenSocial.

It makes use of Java Message Service (JMS), Java Persistence API (JPA), Lucene and Google Web Toolkit (GWT). It makes use of the Apache JServ Protocol (AJP), OAuth and Representational State Transfer (REST).

History
The development of the Eureka Streams software began at Lockheed Martin in early 2009. The open source project was first announced publicly at the Enterprise 2.0 Conference in Boston, Massachusetts in July 2009. However, the name "Eureka Streams" was chosen later that summer and subsequently revealed publicly with the open source project announcement on July 26, 2010.

The core team behind Eureka Streams resides in the CIO Office of Lockheed Martin Information Systems & Global Solutions. Its principal members include Shawn Dahlen, Chris Keohane, Brian H. Mayo, Steve Terlecki, Blake Caldwell, Chad Scott, Rob Keane, and Anthony Romano.

When the open source project was first announced, the open source community initially reacted with some surprise. This is partly because the originating company is a large aerospace & defense company. In addition, the project apparently bucked the trend of fewer enterprises participating in open source projects.
