Twitter began using NoSQL last year as it rolled its systems onto the widely popular Cassandra system (used by large web properties such as Digg and Facebook).  Apparently they're not satisfied with just one non-relational datastore, because they are currently working on a storage engine for timelines backed by a different NoSQL, Redis.  The experiment is called Haplocheirus (named after a dinosaur - one of the earliest links between birds and reptiles).  Some of the goals of the project are high availability, structured vectors, and elimination of client-side hashing.

Inspired by the BlazeDS framework, RedFX is a framework that facilitates easy connection between JavaFX clients and Java EE backends.  The framework facilitates remote object synchronization, messaging, and WebServiceClient.  The project creator is in the process of open-sourcing RedFX and integrating it under the JFXtras umbrella.
