Keynote: Our Concurrent Past; Our Distributed Future - QCon London

It's hard to believe a world existed before multi-core. Developers today use concurrency in all aspects of their software, every day, as though it is second nature. Join us at QCon London & take a journey through concurrency's explosion onto the mainstream over the past 15 years. We will also look at some of today's hottest trends (cloud, IoT, microservices) and attempt to predict what lies ahead not only for concurrent programming, but also distributed, from now to 15 years into the future.
