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.
Managing libraries and dependencies is tedious. Clojars is a new hosted repository for Clojure libraries inspired by Ruby Gems and Gemcutter. Together with a new build tool, Leiningen, Clojars takes the pain out of library management. InfoQ talked to Alex Osborne about Clojars and how it works.
Documentation generator Yard's 0.4 release adds new features such as a live documentation server which allows users to comment on the docs. The new tool Gem Bundler allows flexible dependency management.
For years the norm for developers was to work in an iterative and incremental manner but for database developers to work in a more serial manner.
