JetBrains gained a lot of attention when they released an open source version of thier IntelliJ IDEA development platform. For Ruby and Ruby on Rails users, JetBrains created the RubyMine IDE, which is built on the principles of IntelliJ. However, RubyMine did not start out as a plugin like comperable Ruby IDE's for Eclipse and NetBeans. In an exclusive interview, DZone spoke with RubyMine's lead developer at JetBrains, Dmitry Jemerov. The interview covers the recently introduced RubyMine 2.0, which features improved code refactoring and added support for popular Ruby/Rails technologies. Although RubyMine hasn't been around for very long, it has quickly become the one of the most natural Ruby/Rails development environments.
