I gave Rails3 a try and to do so I installed the new gems, like RSpec2.

Dear Stackoverflow, I have a nice CamelCase string such as ImageWideNice or ImageNarrowUgly. Now I want to break that string in its substrings, such as Image, Wide or Narrow, and Nice or Ugly. I thought this could be solved simply by camelCaseString =~ /(Image)((Wide)|(Narrow))((Nice)|(Ugly))/ But strangely, this will only fill $1 a...

So I tried to create a new rails app to reduce the complexity, but that doesn't create the dispatch.fcgi file in the public folder, which leads me to think that my RubyIIS setup is wrong.
