You can easily experiment with Ruby 1.9 to try out a gem or two, and if you run into issues, you can safely retreat back to 1.8.x (after you report the Ruby 1.9 problems to the gem's maintainers, of course). The latest version includes single-line commands that install the various Ruby versions for you. Wanna try out Ruby 1.9.1? Just type <code>install_ruby_191</code>, and the Ruby Switcher handles the rest. The Ruby Switcher gives you shell-specific Ruby versions: while one terminal window is testing out a gem or app in Ruby 1.9, you can have another terminal performing the same tests with Ruby 1.8.7 (or JRuby, or Ruby 1.8.6, or REE, or Leopard Ruby, etc.).

In this report I’ve compared the performances of several Ruby implementations against a set of synthetic benchmarks. The implementations that I tested were Ruby 1.8 (aka MRI), Ruby 1.9 (aka Yarv), Ruby Enterprise Edition (aka REE), JRuby 1.1.6RC1, Rubinius, MagLev, MacRuby 0.3 and IronRuby. 2008-12-09T17:43:21+00:00 false 1320 2008-12-09T17:43:21+00:00 0 Grant Michaels has put together <a href="http://grantmichaels.wordpress.com/2008/11/30/getting-the-merb-on-linode/">a walkthrough of installing Merb - running on a JRuby stack - on a Linode VPS.</a> It'll work for Linux generally, however, and has even be useful to me on OS X. It's a bit of a mish-mash, but you'll probably find something useful in here. 2008-12-04T05:56:04+00:00 false 1290 2008-12-04T05:56:04+00:00 5
