Azul Systems have announced that they are making their pauseless Zing JVM freely available to Open Source developers and projects for use in development and testing.
The Common ReusAble SHell (CRaSH) is an interactive shell (with history support and autocompletion) that attaches to a running JVM and can execute several commands for retrieving JVM statistics or changing JVM internals on the fly. It can be used for remote monitoring and administration of existing Java applications and it is fully extensible via custom Groovy scripts.

Rich Hickey spoke at the Clojure/West conference last weekend about his newest venture, Datomic, which he describes as “a distributed database designed to enable scalable, flexible and intelligent applications, running on cloud architectures.” Datomic sits on Amazon’s DynamoDB, and embeds Datalog, a subset of Prolog, to move queries into the application.
