The Alliance for Open Media’s focus is to deliver a next-generation video format that is: - Interoperable and open; - Optimized for the Internet; - Scalable to any modern device at any bandwidth; - Designed with a low computational footprint and optimized for hardware; - Capable of consistent, highest-quality, real-time video delivery; and - Flexible for both commercial and non-commercial content, including user-generated content. This package contains the reference encoder and decoder.
Aspect-Oriented Programming (AOP) offers a better solution to many problems than do existing technologies, such as EJB. AOP Alliance intends to facilitate and standardize the use of AOP to enhance existing middleware environments (such as J2EE), or development environements (e.g. Eclipse). The AOP Alliance also aims to ensure interoperability between Java/J2EE AOP implementations to build a larger AOP community.
Apache Airflow (or simply Airflow) is a platform to programmatically author, schedule, and monitor workflows. When workflows are defined as code, they become more maintainable, versionable, testable, and collaborative. Use Airflow to author workflows as directed acyclic graphs (DAGs) of tasks. The Airflow scheduler executes your tasks on an array of workers while following the specified dependencies. Rich command line utilities make performing complex sugeries on DAGs a snap. The rich user interface makes it easy to visualize pipelines running in production, monitor progress, and troubleshoot issues when needed.

Cassandra brings together the distributed systems technologies from Dynamo and the data model from Google's BigTable. Like Dynamo, Cassandra is eventually consistent. Like BigTable, Cassandra provides a ColumnFamily-based data model richer than typical key/value systems. For more information see http://cassandra.apache.org/
