Two weeks ago, I had the pleasure of attending the BOB Konferenz 2016 in Berlin, Germany.
BOB is the forum for developers, architects and builders to explore technologies beyond the mainstream and to discover the best tools available today for building software.
I gave a talk on functional reactive programming; slides and videos are available.
I particularly liked the talk by Andres Löh on the Servant library, which allows you to scaffold a REST API entirely on the type level, and the talk by Stefan Wehr on the Swift language by Apple, which showed that functional programming already has become mainstream.
