Maven and JRuby Roundup: Maven_gem Brings Maven Libs to RubyGems, GemCutter Inspires JavaGems

by Mirko Stocker on  Dec 18, 2009 1

JRuby's Charles Nutter is making Maven artifacts installable as RubyGems. An alternative to using Maven is JavaGems, built on RubyGems, Bundler and Gemcutter to make it easier to install libraries for Scala, Clojure and other JVM languages. Also, JRuby gets the ability to generate real Java classes.

Clojure 1.1 Adds Transients, Chunked Sequences for Efficiency

by Werner Schuster on  Dec 17, 2009

Clojure 1.1 RC1 is out and cuts the overhead of functional programming with a few new constructs: transients bring controlled mutability for persistent data structures; chunked sequences make lazy sequences more efficient. InfoQ takes a look at what makes these improvements work.

JRuby and Clojure - A Good Match?

by Werner Schuster on  Feb 11, 2009 3

Clojure is a JVM based LISP with interesting properties for concurrency (persistent data structures, STM). New libraries for Clojure are popping up - and some of them are inspired by Ruby libraries such as HAML, ActiveRecord, Rack, and others. We also look at combining JRuby and Clojure to get the best of both Ruby and LISP world, as well as access to technologies such as STM.
