From my presentation at OSCON 2014 http://www.oscon.com/oscon2014/public/schedule/detail/37779 Abstract: There’s only one way to do it here at PayPal – with a framework. Everything you’ll ever need is done if you stay inside the lines. Imagine my reaction when I joined PayPal with Scala and high hopes. We have many reasons to avoid the monolithic framework, so we were going against the grain from day 1. My team came on to “shake things up” and we’ve been doing just that. We brought Scala to PayPal, built small components to defeat “framework-itis” and generally pissed some people off. Now we want to open source the stuff we’re building. I’m going to talk about our challenges so far, and how we overcame them. I’ll have tales (both funny and sad) to tell about my experience so far, and I’ll share plenty of lessons learned along the way.
