NASA NEBULA | About NEBULA
NEBULA is a Cloud Computing environment developed at NASA Ames Research Center, integrating a set of open-source components into a seamless, self-service platform. It provides high-capacity computing, storage and network connectivity, and uses a virtualized, scalable approach to achieve cost and energy efficiencies.
The fully-integrated nature of the NEBULA components provides for extremely rapid development of policy-compliant and secure web applications, fosters and encourages code reuse, and improves the coherence and cohesiveness of NASA's collaborative web applications. It is used for Education and Public Outreach, for collaboration and public input, and also for mission support.
Built from the ground up around principles of transparency and public collaboration, NEBULA is also an open-source project. NEBULA is built on the NEBULA platform.

With the recent brouhaha over Twitter’s scalability problems, I thought, wouldn’t it be fun to write a Twitter clone in Erlang?
Last weekend was cold and rainy here in Palo Alto, so I sat down and hacked one, and thus Twoorl was born. It took me one full day plus a couple of evenings. The codebase is about 1700 lines (including comments).
Twitter is dead, long live to Twoorl. The code is open source.
