Haskell Weekly News
Issue 96 - December 06, 2008

   Welcome to issue 96 of HWN, a newsletter covering developments in the
   [1]Haskell community.


   Haskell haikus. Gwern Branwen [2]announced that he has collected all
   known haikus about Haskell and put them on a [3]wiki page. Add more!

   Platforms that GHC supports. Simon Peyton-Jones [4]linked to a [5]new
   page clearly articulating what platforms GHC supports, and what
   platforms its maintainers would like it to support. If you're
   interested and willing to help sponsor a "Tier 2" platform, let them

   Using Data Parallel Haskell. Manuel Chakravarty [6]announced a new
   [7]wiki page with documentation for Data Parallel Haskell.

   DrHylo 0.0.1. Hugo Pacheco [8]announced the [9]release of [10]DrHylo, a
   tool for deriving hylomorphisms from a restricted Haskell syntax. It is
   based on the algorithm first presented in the paper Deriving Structural
   Hylomorphisms From Recursive Definitions at ICFP'96 by Hu, Iwasaki, and
   Takeichi. The generated code can be run with [11]Pointless Haskell,
   allowing the visualization of the recursion trees of Haskell functions.

   pointless-haskell 0.0.1. Hugo Pacheco [12]announced the [13]release of
   [14]Pointless Haskell, a library for point-free programming with
   recursion patterns defined as hylomorphisms, inspired in ideas from the
   PolyP library. The re-implementation of the library using type
   functions (in opposition to classes with functional dependencies)
   enables a type-level view of data types as the fixed points of functors
   and provides a better experience to the users in terms of code sanity.
   The library also features the visualization of the intermediate data
   structure of hylomorphisms with GHood.

   Projects that depend on the vty package?. Corey O'Connor [15]asked
   whether there are any other projects that depend on the [16]vty
   package. If so, let him know! The package also has a new [17]trac and

   haskell-src-exts 0.4.4. Niklas Broberg [18]announced the release of
   [19]haskell-src-exts 0.4.4, which adds support for pragmas.

   ChristmasTree 0.1. S. Doaitse Swierstra [20]announced the release of
   the [21]ChristmasTree package, which stands for "Changing Haskell's
   Read Implementation Such That by Manipulating Abstract Syntax Trees it
   Reads Expressions Efficiently".

   TTTAS. S. Doaitse Swierstra [22]announced the release of [23]TTTAS, a
   library for typed transformations of typed abstract syntax.

   GHood. Hugo Pacheco [24]announced that GHood, a graphical backend for
   the lightweight Hood Haskell debugger, has now been [25]released as a
   Cabal package.


   Animated line art. Andrew Coppin [26]asked for ideas on writing Haskell
   to generate some animations.


   Scala job in Boston writing quantitative finance software. Paul
   Chiusano [27]announced that [28]ClariFI is looking to hire developers
   with a strong background in functional programming to do a mixture of
   Scala and Java programming. ClariFI is a small company (about 15
   developers) that specializes in software for quantitative investment
   management. This position is for the Boston office. If you're
   interested, send him an email.
