Velocity Culture Ballroom CD
Average rating: ***..
(3.83, 12 ratings)

In 2009 the Facebook Engineering team set out to make the site twice as fast. While Bobby Johnson’s talk will focus on the culture and processes we used to achieve that goal, this presentation will describe the technical innovations we made. It will specifically highlight two technologies: BigPipe, which pipelines the process for generating a webpage, and Primer, a simple JavaScript API that enables progressive enhancement.
