The need for machine-learning techniques like clustering, collaborative filtering, and categorization has steadily increased the last decade along with the number of solutions needing quick and efficient algorithms to transform vast amounts of raw data into relevant information. Apache Mount 0.3 has been announced on March, adding more functionality, stability and performance.
FlightCaster recently open sourced Crane, a tool for distributing and remotely controlling Clojure instances, currently specialized for EC2. Incanter is a Clojure library and tool that makes R-like statistical computations easy with Clojure. Also: the build and dependency management tool Leiningen 1.0 is now available.
David Pollak, found of the Lift web framework and "Beginning Scala" author, has announced a new initiative "Goat Rodeo" that aims to bring data modeling into the 21st century.
With the multiplicity of existing remoting mechanisms it is often necessary to build clients in a way that allows to swap/introduce new protocols with no/minimal impact to the client’s implementation. A new framework – CRISPY - provides support for such implementations.
Tim Bray of Sun Microsystems writes of the Fallacies of Distributed Computing; He observes that despite its profound implications when designing distributed systems, “you don’t often find them coming up in conversations about building big networked systems”.
