Through teamwork, an agile team can ensure the quality of its project's architecture, code hygiene, and other non-functional requirements by explicitly creating tasks for those concepts in each sprint. Alexander von Zitzewitz explains the importance of this method of agile development and how the use static analysis of code bases can help the "hard sell" of intentional architecture to management.

Duncan Coutts explains the nature of Concurrency and Parallelism in Haskell, its threading and STM implementation, Erlang OTP's influence on CloudHaskell for distributed programming, Monads, and more.
Big Data means more than just the size of a dataset. Pavlo Baron explains different ways of applying Big Data concepts in various situations: from analytics, to delivering content, to medical applications. His larger vision for Big Data ranges from specialized Data Scientists, to learning Decision Support Systems, to helping mankind itself.
