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.

  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.

  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.

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.
