Tim Williams describes one of the world's largest commercial Haskell deployments (Barclays) and shares some experiences and insights gained using Haskell to build domain specific languages.
Simon Thompson shows the particularities of functional programming refactoring through examples in Haskell and Erlang, and discusses what lays ahead for FP refactoring in the next 10 years.
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.
Creighton Kirkendall discusses how polymorphism is implemented in Clojure, Ocaml, Haskell and Scala.
Adam C. Foltzer introduces Molog, a typed functional logic programming language written in Haskell.
Simon Marlow introduces some of the main features of Concurrent Haskell: forking threads, MVars, asynchronous I/O, simple inter-thread protocols.
Michael Feathers describes an approach toward planning the design of the functional portions of an application by using a variation of Haskell type expression syntax.
Bryan O'Sullivan introduces some of the technologies pioneered in the Haskell community to streamline software development and reduce operational costs, while producing beautiful code.
Jesper Louis Andersen presents a case study of a BitTorrent client written in Haskell based on reusable patterns, drawing conclusions on what is great and not so great in Haskell and comparing it with a similar Erlang client.
Philip Wadler discusses second-order quantification, from its inception in the symbolic logic of Frege through to the generic features introduced in Java 5, touching on aspects of faith and evolution.
Michael Snoyman presents Yesod, a web framework written in Haskell and containing a web server, templating, ORM, libraries (templating, gravatar, etc.).
Bryan O'Sullivan presents a case study of a small startup that chose Haskell for its server-side code, outlining the advantages and disadvantages of using Haskell to quickly create a solid solution.
