This talk will show Ruby running in HTML script-tags for writing HTML applications in Ruby, as well as embedding Ruby in a non-Ruby application for extensibility. All demos can be found on http://github.com/jschementi/rubyconf2009
This talk uses the IronRuby implementation, which runs on most major operating systems, as well as most modern browsers as a replacement for JavaScript (as browsers are becoming platforms in their own right). It can also reach across the programming language barrier to use code written in other languages (static or dynamic), and allows those other languages to embed IronRuby.
