Hello,
There are quite a few versions of Ruby 1.9 floating around. There are a few Ruby 1.9 builds for the different operating systems at the official Ruby language site here:
http://www.ruby-lang.org/en/downloads/
There are also other 1.9 versions at Ruby Forge:
http://rubyforge.org/frs/?group_id=167&release_id=38052
What are the differences between them? And which one should one be learning?
I ask this because I started taking a Ruby course at http://rubylearning.com/ and they recommend downloading ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32] but do not really state why. Also I see other people using different builds of 1.9 so I am curious about the differences.
Thanks,
caeious
