SlicedBread is a library that makes it simpler to program multithreaded applications in Java. It does so by doing away with "classic" multithreaded staples - that is, shared state using thread-safe objects - in favor of a set of single-threaded processes that send and receive immutable messages. In a sense it is inspired by Erlang's messaging system. In another, the over 400 rich pages of "Java concurrency in practice" show how hard it is to write and debug a good-mannered multithreaded application in Java.
WombatDialer is a platform to provide mass outbound calling. This can be used to implement many different services. By offering a set of ready-to-use components and a monitoring GUI, it lets you create complex solution in minutes. It can work on predefined call lists or can dynamically create them over an API (e.g., dial number X after 10:30AM). It shares the load on one or more PBX servers and has flexible rescheduling logic to handle missed calls. It is built to be used with your existing Asterisk PBX, and does not require separate servers or a separate set of lines. It can call over VoIP or through the public telephone network. It is built to integrate with your business processes, and can receive calls to be made over HTTP and/or notify an external system in realtime of calls made and results gathered. It works natively with the QueueMetrics Call-Center Monitoring Suite to produce state-of-the-art campaign analyses and insight.
ObjectiveSync is a thin JDBC object persistence library. If features querying done in SQL, centralized object marshaling and unmarshaling where each object should know how to sync itself and its descendants, a single syntax for inserting and updating, Ruby-like objectivized JDBC fetching with exception handling, user-definable deep fetching and updating (almost Hibernate-like), batch API to avoid round-trips when submitting multiple queries, stats collection, and more.
