Yahoo announced on Thursday the addition of the Flash Developer Center and Ruby Developer Center to its Yahoo Developer Network (http://developer.yahoo.com). Each center contains how-to articles, downloadable components, access to mailing lists and links to external resources. Promoting Flash and Ruby makes sense, because both languages have become very popular for building next-generation applications, said David Smith, a Gartner Inc. analyst. http://www.webwereld.nl/articles/42988/yahoo-promotes-flash--ruby-mashups.html
