Title: Twitter - Engineering for Real-Time
Abstract: The biggest engineering problems that twitter faces are not due to its large user base, or due to the huge amount of data being pumped through its system -- it is its "real-time constraint". The name of the game at twitter is "now": whether that means getting @ladygaga's, @barackobama's, or @raffi's tweets out to their followers within seconds (or faster!) of them writing their 140 characters; or it means doing a search to find out what's happening right now in the world because an earthquake happened, people are talking about a television show, or you want to know where your friends are. Very few other systems have this constraint, and very few engineering teams rise to its challenge.
Speaker Bio: At @twittereng, @raffi is the Director of the Applications Services group, the custodians of Twitter's core logic → his teams manage, amongst other things, the business logic, scalable delivery, APIs, and authentication of Twitter's application. His group, from the @twittereng side, helped create the iOS 5 Twitter integration as well as the "The X Factor" + Twitter voting mechanism. Previously, he was the lead of the public APIs as well as being the one of those behind Twitter's Geospatial APIs. Before Twitter he used to create technologies to help people frame their personal energy consumption against global energy production (Wattzon - Business Week's "Best Idea" 2008), and also ran a consulting company building off-the-wall projects. At one point, he used to teach at NYU’s ITP (created the class Every Bit You Make) and spent way too much time as a student at MIT and the MIT Media Lab (Internet 0 - Scientific American September 2004).
