Rails não Escala Tuesday, January 20, 2009

Tuesday, January 20, 2009 FUD: http://www.techcrunch.com/2008/05/22/twitter-at-scale-will-it-work/

To put things into perspective, though, Friendster was written in Java to start, and switched to PHP. Myspace was written in ColdFusion and transitioned to ASP.NET. When people run into problems scaling sites they often think that the language is the problem, but I think Blaine Cook it’s rarely the case. http://www.akitaonrails.com/2008/6/17/chatting-with-blaine-cook-twitter Tuesday, January 20, 2009 http://www.akitaonrails.com/2008/6/17/chatting-with-blaine-cook-twitter

“They serve up 23 million visitors a month. The conversion resulted in 20,000 lines of Ruby code instead of 125,000 lines of Java code, and most importantly eased the difﬁculty they had in maintaining it. Once complete, and optimized their site is now faster than before. They also completed the rewrite in three months with four developers.” http://www.railsonwave.com/railsonwave/2008/6/4/yellowpages-com-migrates-to-rails Tuesday, January 20, 2009 http://www.akitaonrails.com/2008/11/21/rails-podcast-brasil-qcon- special-john-straw-yellowpages-com-and-matt-aimonetti-merb http://www.rubyonrailsexamples.com/sites-on-rails/yellowpagescom- goes-ror/
