Try Ruby online, and learn it the interactive (Ajax) way
Never heard of Ruby? Its that new hot language that is at the tipping point of blowing away all existing languages;-)
Read about it at http://ruby-lang.org, and of course don’t forget the great Ruby on Rails framework at http://www.rubyonrails.org that lets you build a data driven, Ajax style web site garanteed under 15 minutes. And the book “Agile web development with Rails” is absolutely a great reading.
To get a touch of the language without installing the whole shabang and even get an interactive training (Ajax style), check out http://tryruby.hobix.com/. It is really cool! (Uhhh… needs Firefox by the way, sorry!) <== UPDATE: Problem is solved, works on IE and Safari now, but Opera seems to be a problem!! Great work!!
