Roman Gonzalez and Tavis Rudd discuss techniques for shortening the ClojureScript development cycle by using the same codebase for clj and cljs and automatically running tests on the JVM.
Daniel Spiewak discusses how modern languages such as Scala, Clojure, and Haskell have moved beyond the simple lambda calculus paradigm, being better suited for large application architectures.
Brandon Bloom introduces Factor and demonstrates Factjor –concatenative DSL - and DomScript –DOM library written in ClojureScript - in the context of concatenative programming.
Creighton Kirkendall discusses how polymorphism is implemented in Clojure, Ocaml, Haskell and Scala.
Hugo Duncan introduces Ritz, a set of tools for debugging, inspecting, project reloading, with codeq and lein integration, showing how to use it with nrepl.el in Emacs.
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.
David Greenberg introduces Piplin, a DSL that allows a subset of Clojure to be automatically converted into a hardware description, which can then be placed onto an FPGA or made into a silicon chip.
Chris Houser and Jonathan Claggett compare macros with monads, suggesting when it is better to use each of them, and pondering what could be done to improve them.
Antoni Batchelli discusses building an automated infrastructure in Clojure.
Rich Hickey explores the nature of design and composition and how it impacts the software development practice and tools.
Gary Fredericks discusses macros, what they are, how to write good ones, when to use them and when to avoid using them.
