Yes, you're correct, it was not an either-or proposition, I'm sorry, they dropped them both. Seriously, I'm curious, what public facing, or any facing, components does Twitter use that is written in Ruby and/or Rails? A Google search for "twitter rails" brings up the usual got dumped threads. A similar search, but this time, "twitter scala" brings up, as a first result "Scala School" for Twitter engineers, followed by a bunch of threads on the Twitter + Scala marriage. Don't worry, Scala has its own issues (Yammer, for example, ditched Scala for Java due to, ironically enough, scalability issues). |
