Welcome to the Cassandra Project

Cassandra is a highly scalable, eventually consistent, distributed, structured key-value store. 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.

Cassandra was open sourced by Facebook in 2008, where it was designed by one of the authors of Amazon’s Dynamo. In a lot of ways you can think of Cassandra as Dynamo 2.0. Cassandra is in production use at Facebook but is still under heavy development.

The new version of QuickTime included with Snow Leopard (called QuickTime Player X) is almost a complete overhaul of the previous version, from the look and feel of the application windows right down to the preferences menu (or lack thereof). If you were looking to change some options but don’t know where to start, our Preference Pane can help you enable or disable many of QuickTime’s features. It is currently in it’s initial release (version 1.0) with an update coming soon to fix the only known bug. For more information on version 1.0, please read the release notes, which is also included in the Preference Pane bundle. You can see a screen shot of the application running below, and when you are ready, download it here.
