Alex Miller discusses Clojure’s approach to data, comparing it with OOP’s approach, and covering various related topics such as mutation, state vs. value, primitive and composite data.
Carin Meier shares from her experience doing functional programming in Clojure for flying robots.
Gerald Sussman explains how programming can help understand Analytical Mechanics and Differential Geometry, and make some concepts of General Relativity come alive. Indeed, a well-crafted program is an expression of an idea, and it may be a work of art.
Chris Ford shows how to make music starting with the basic building block of sound, the sine wave, and gradually accumulating abstractions culminating in a canon by Johann Sebastian Bach.
Jim Powers presents ways to use functional programming techniques and the new Async framework for Scala to regain compositionality while retaining the power of the model.
Heather Miller shows how to perform asynchronous programming in Scala and Java with composable pipelines using the Futures and Promises API.
Peter Pilgrim introduces Scala to advancing beginners: getting the most out of Scala, working with popular Java frameworks, the build tools and some of the new features of Scala 2.10.
Joe Armstrong outlines the architectural principles needed for building scalable fault-tolerant systems built from small isolated parallel components which communicate though well-defined protocols.
Dean Wampler supports using Functional Programming and its core operations to process large amounts of data, explaining why Java’s dominance in Hadoop is harming Big Data’s progress.
Kevin Scaldeferri reports on using Scala for an SBT plug-in, for unit and functional testing, type-safe shared configuration using Zookeeper, and live inventory with WebSocket and Akka Actors.
David Craelius tells the story of Klarna building an online payment system in Erlang and their approach to solving the nightmare of technical debt accumulated during a period of fast expansion.
Torben Hoffmann looks at the status of Erlang using the technology life cycle lenses of Geofrey More and in particular discuss if Erlang is before, in or after the Chasm.
