Exercism.io helps developers to increases their craftsmanship in a language through feedback and discussion. It’s a community and tool where developers can write code and discuss it to strengthen their problem-solving skills. InfoQ did an interview with the creator of exercism Katrina Owen and with Richard Thomson who contributed the C++ language track for exercism.
Silk has recently open-sourced a REST framework for Haskell, called "rest". It provides a DSL for defining REST services which can then be run in popular web frameworks such as happstack. This comes with features such as type-safe URLs, abstraction of format-type support, and a clean separation of API specification and business logic.
Facebook has open-sourced Haxl, a library for efficient, concurrent data-access. The library leverages the traditional strengths of Haskell such as expressive type system, correctness and safety guarantees, as well as GHC's high performance run-time to solve the thorny issue of implicit, concurrent data access.
GHC 7.8.1 was recently released, bringing several language, compiler and performance improvements. Haskell can now be compiled for iOS, and sports new features such as Closed Type Families, Roles, Overloaded Lists, Pattern Synonyms.
FP Complete has launched Haskell Center, their new Haskell IDE and application server. The IDE is browser based, and together with their application server, should make it much easier to create and run web based Haskell programs.
The well-known Haskell implementation GHC is moving from Darcs to a repository on GitHub, citing wider tool support and faster operations.
Embedding C in Ruby or Rails applications is a way to fix performance bottle necks. RubyInline made this easy for C. Mark Wotton recently created Hubris, a bridge which makes it possible to call Haskell code from Ruby.
This interview with Paul Hudak, recorded at QCon San Franscisco 2008, begins with a discussion of when to introduce difficult Haskell concepts like monads; moves to a discussion of the philosophy of higher order programming, the success and influence of Haskell, its use in the mainstream, and concludes with the idea of teaching computer music and Haskell simultaneously.
In this interview made by InfoQ’s Sadek Drobi, Don Syme, a Senior Researcher at Microsoft Research, answers questions mostly on F#, but also on functional programming, C# generics, type classes in Haskell, similarities between F# and Scala.
In this presentation recorded during QCon London 2008, Simon Peyton-Jones advertises the need for programming purity achieved especially through use of functional languages and the increased attention given to functional programming.
In this interview made during QCon SF 2008, Erik Meijer talks about less known LINQ features, like the ability to do meta programming or the fact that LINQ works against any data collection that implements the sequence operators. Meijer also talks about the differences between functional languages and objectual ones, asynchronous computation, and the evolution of languages.
In this interview filmed at QCon SF 2008, Lennart Augustsson talks about writing DSLs in Haskell, presenting the advantages offered by the language. In that context, he talks about embedded DSLs, static and dynamic languages, syntax and semantics, monads and many other related topics.
One of co-authors of the Real World Haskell book, John Goerzen, talks in a recent interview to O’Reilly about purity, laziness, recursiveness and many other subjects that make Haskell worth learning but may also be a source of reluctance for people coming from object oriented or imperative programming.
In the beginning of last year, Ehud Lamm launched on Lamba the Ultimate a thread about programming languages predictions for 2008. Several subjects popped up: concurrency, functional programming, future of Java, Ruby, C++, and many others… What really happened in 2008 and what are the prospects for 2009? Bloggers have addressed these questions on demand of James Iry, echoing at last year thread.
