Issue 116 - May 02, 2009
---------------------------------------------------------------------------

   Welcome to issue 116 of HWN, a newsletter covering developments in the
   [1]Haskell community.

Announcements

   GHC 6.10.3 prerelease. Ian Lynagh [2]announced a [3]prerelease
   [4]version of GHC 6.10.3. There have been [5]very few changes relative
   to 6.10.2. Unless any major problems are uncovered, the final release
   is expected to be built in a couple of days.

   graphviz-2009.5.1. Ivan Lazar Miljenovic [6]announced version 2009.5.1
   of the [7]graphviz library, which provides a Haskell interface to the
   [8]GraphViz program. Major changes include support for polyparse >=
   1.1, dependency on GHC 6.10.*, functions from the [9]Graphalyze
   library, and more.

   priority-sync-0.1.0.1: Cooperative task prioritization.. Christopher
   Lane Hinson [10]announced the release of the [11]priority-sync package
   for cooperative task prioritization.

   HaL4: Local Haskell meeting, Halle/Saale, Germany, June 12. Henning
   Thielemann [12]requested proposals for talks for [13]HaL4, a local
   Haskell meeting in Halle, Germany on June 12.

   TraverseAccum: an effectful accumulating map.. Florent Balestrieri
   [14]posted some code implementing an effectful accumulating map.

   LondonHUG talk: Engineering Large Projects in Haskell. Don Stewart
   [15]posted [16]slides from last week's [17]London HUG talk, which
   attempts to document some of the tips and tricks Galois has accumulated
   using Haskell commercially for the past 10 years.

   atom-0.0.2. Tom Hawkins [18]announced the release of [19]atom, a
   Haskell DSL for designed hard realtime embedded programs. Eaton is
   using it to control hydraulic hybrid refuse trucks and shuttle buses.

   Bamse-0.9.4, a Windows Installer generator. Sigbjorn Finne
   [20]announced a new version of [21]Bamse, a package and application for
   letting you quickly put together Windows Installers for your software
   projects/products from within the comforts of Haskell. New in this
   release is the support for generating MSIs from your Cabal projects,
   having them either be built from source or just have them be installed
   and registered at install-time.

   Dutch Haskell Users' Group (first meeting: May 6th). Chris Eidhof
   [22]announced the first meeting of the newly formed [23]Dutch Haskell
   Users' Group (DHUG), on May 6th at 19:30 in Utrecht.

   Haskell Symposium Submission site now open. Stephanie Weirich
   [24]announced that [25]submission to the Haskell Symposium is now open.
   The submission deadline is May 8.

   OpenGL, GLUT, OpenAL, and ALUT updates. Sven Panne [26]announced
   [27]new [28]bugfix [29]releases for the [30]OpenGL, [31]GLUT,
   [32]OpenAL, and [33]ALUT packages.

   control-monad-exception-0.1: Explicitly typed exceptions. Pepe Iborra
   [34]announced the [35]control-monad-exception package, which provides
   explicitly typed exceptions for Haskell. The type of a computation in
   the EM monad carries a list of the exceptions that the computation may
   throw. A exception is raised with 'throw', which in addition adds it to
   the type, and captured with 'catch', which correspondingly removes it
   from the type. Only safe computations (all exceptions handled) can
   escape from the monad.

   Haskell File Manager. Michael Dever [36]announced the first release of
   [37]Haskell File Manager, a program for viewing/managing the files on
   your computer. It has all the common functionality you would expect
   from your current file manager, copying, moving, deleting, renaming,
   opening and searching.

   uu-parsinglib-2.0.0. S. Doaitse Swierstra [38]announced the release of
   [39]uu-parsinglib, the first version of the new parsing combinator
   library package from Utrecht University. Features include online result
   construction, much simpler internals than the combinators in the uulib
   package, error correction, parsing ambiguous grammars, a monadic
   interface, and more.

   Takusen 0.8.4. Alistair Bayley [40]announced version 0.8.4 of
   [41]Takusen, a database package; this is mostly a "get it working with
   ghc-6.10" release.

Discussion

Google SoC: Space profiling reloaded. Patai Gergely [42]asked for ideas
   on his Google Summer of Code project to [43]improve the Haskell space
   profiling experience.

Quotes of the Week

     * MonadState: Do not try to change the state; that's impossible.
       Instead only try to realize the truth: There is no state.
     * Baughn: Those who would give up essential laziness for a little
       ephemeral performance, deserve neither laziness nor performance.

     * bos: Crummy languages give static types a bad name.
