This is the ReactiveCocoa presentation from MobiDevDay 2013 http://mobidevdaydetroit.com
ReactiveCocoa (RAC) is an Objective-C framework for Functional Reactive Programming. It builds off of Cocoa's own key-value observing mechanism to provide a high-level, declarative API for composing operations on streams of data, state, and asynchronous tasks. What does all of that mean? We'll find out as we explore RAC's potential for helping us better reason about the creation of our apps.

Go is a general-purpose language that bridges the gap between efficient statically typed languages and productive dynamic language. But it’s not just the language that makes Go special – Go has broad and consistent standard libraries and powerful but simple tools. This talk gives an introduction to Go, followed by a tour of some real programs that demonstrate the power, scope, and simplicity of the Go programming environment.
