Rails Conf Europe 2008 - Day 3

Posted by arungupta on September 5, 2008 at 10:17 PM PDT



Last day of Rails Conf Europe 2008 ( href="http://blogs.sun.com/arungupta/entry/rails_conf_europe_2008_end">Day
1 & href="http://blogs.sun.com/arungupta/entry/rails_conf_europe_2008_day">Day
2), and it's finally over!



David Black's opening session talked about href="http://en.oreilly.com/railseurope2008/public/schedule/detail/4919">Ruby
and Rails Symposium: Versions, Implementations, and the Future.
Here is a brief summary of MRI Ruby versions:

  • Ruby 1.8.6
    • Bread and butter for many of us
  • 1.8.7
    • 1.8 with lots of backported 1.9 features
    • Help with migration to 1.9
    • Not gaining traction, is it ?
  • 1.9.0
    • First release of 1.9
    • Not particularly feature stable
    • Not in wide production use.
  • 1.9.1
    • Feature freeze 9/25
    • Release Christmas 2008 (planned)
    • Expected to be more stable

The
talk showed some of the new features coming up in Ruby 1.9.x. An
informal survey of audience indicated the following numbers:

  • 4 - How many are using 1.8.7 ?
  • 98% - How many are using 1.8.6 ?
  • 1 - How many are using 1.9.0 ?
  • 4 - Tried 1.8.7 and not switching
  • 3 - Tried 1.9 and not switching
  • 85% - Never tried 1.9

JRuby
is an alternative implementation of Ruby that runs on Java VM.
 And when prompted, I quoted all the JRuby numbers (75% memory
improvement with upcoming Rails 2.2, 33,000 assertions from Ruby Spec
and 22,000 tests for Ruby 1.8.6 compliance, Ongoing work on Ruby 1.9
compliance). JRuby "It's just Ruby" - knowing Java is not a
pre-requisite to run JRuby for your Ruby or Rails applications!



In  href="http://en.oreilly.com/railseurope2008/public/schedule/detail/3481">Developing
Ruby and Rails applications with the NetBeans IDE
talk, Erno & Petr showed all the cool features of Ruby/Rails
editing, syntax highlighting, debugging, project creation, refactoring
and many more. You can find all about it href="http://ruby.netbeans.org">here.
