Haskell might be “the closest thing to a secret weapon” when building server-side software, writes Better co-founder Carl Baatz, summarizing their four-year journey using Haskell in production.
A new Strict language extension to Haskell aims to make it easier to use Haskell for code that is meant to be mostly strict, i.e., evaluated in a non-lazy manner. The feature was recently merged into GHC’s git HEAD and will be included in GHC’s next release.
Mads Torgersen, C# language program manager at Microsoft, has recently outlined a proposal for the introduction of option types for references in C# 7. Option types are meant as a means to make the language safer and reduce the occurrence of null reference exceptions, which, as Torgersen says, are rampant in C# since any reference type can reference a null value.
Frege, named after the German mathematician Gottlob Frege, is a purely functional, strongly typed language for the JVM that is so similar to Haskell that “most idiomatic Haskell code will run unmodified or with only minimal, obvious adaptions”. InfoQ has spoken with Ingo Wechsung, Frege’s creator.
Last month, without any official announcement, Microsoft open sourced Bond - a performant serialization system developed and deployed across dozens of mission-critical, high-scale infrastructure projects internally at Microsoft.
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.
