Interesting slidedeck by Matthias Broecheler introducing 3 graph-related tools developed by Vadas Gintautas, Marko Rodriguez, Stephen Mallette and Daniel LaRocque:
- Titan: a massive scale property graph allowing real-time traversals and updates
- Faunus: for batch processing of large graphs using Hadoop
- Fulgora: for global running graph algorithms on large, compressed, in-memory graphs
The first couple of slides are also showing some possible use cases where these tools would prove their usefulness:

If you never looked into Apache Cassandra, Michaël Figuière’s slidedeck will give you a quick into Cassandra’s main concepts.
Apache Cassandra 1.2 introduces some new features such as a Binary Protocol and Collections datatype that together with the now finalized CQL3 query language provide a new interface to communicate with Cassandra that dramatically shrink its learning curve and simplify its daily use while still relying on its highly scalable architecture and storage engine. This presentation will iterate over all these new features including an overview of CQL3 query language, a look at the new client architecture, and an update on data modeling best practices. Then we’ll see how to implement an enterprise application using this new interface so that the audience can realize that a number of design principles are inspired from those commonly used with relational databases while some other entirely different, due to Cassandra partitioning approach.

I’ve tried to order it chronologically, but most probably I’ve failed. ↩
