Following on five months after the release of the popular JRuby 1.4, the JRuby team have delivered JRuby 1.5! Forgetting the de facto "official" Ruby implementations of 1.8.x and 1.9.1/2, JRuby is the fastest and most stable Ruby implementation available and already has 9 years of progress under its belt. JRuby takes a lot of its performance and versatility from running on the Java Virtual Machine ( JVM ), which has provided JRuby's developers with a solid base from which to optimize how Ruby is implemented. JRuby 1.5.0's release notes provide the full detail, but essentially the biggest new features are: Native launcher for UNIX -based platforms Ant support (effectively a Java based built tool, a la make ) Rails 3 related fixes Updates to the standard library, RubyGems, and RSpec ruby-debug is now included Significantly improved Windows support (a breath of fresh air for Windows-based Ruby developers used to getting second best in the Ruby world) Overall performance improvements
RailsInstaller is a new project from Wayne E Seguin (of RVM fame) that brings RubyInstaller -style simplicity to getting Ruby and Rails set up on Microsoft Windows (XP, Vista, or 7). In a single wizard-driven installation you get Ruby 1.8.7-p330 (with DevKit ), Rails 3.0.3, Git, and SQLite 3. Rails Installer was developed with help from Luis Lavena (a Ruby on Windows expert) and Dr. Nic Williams (Engine Yard's resident Australian comedian ) and its release comes just weeks after Wayne was (re)hired by Engine Yard to work on new open source initiatives. To get started, go to railsinstaller.org , download the "Rails Welcome Kit" and run the installer. There's a screencast you can watch too.
