To celebrate the Ruby 1.9.1 release and demo slideshow-gem-generated all-in-one-web-page presentations (w/ three stylesheets and modes, that is, projection, outline and print) I adapted Bruce Williams’s “Migrating to Ruby 1.9” original PDF slide deck from the Scotland on Rails, Edinburgh, April 2008 talk. S9/S6 tip: Use the T key to toggle between outline and projection/presentation mode. More info about S9/S6 and latest updates such as using your own slide show template packages @ slideshow.rubyforge.org.
