Haskell Weekly News
Issue 112 - April 05, 2009

   Welcome to issue 112 of HWN, a newsletter covering developments in the
   [1]Haskell community.


   hgettext-0.1.5 - GetText based internationalization of Haskell
   programs. Vasyl Pasternak [2]announced a new release of the [3]hgettext
   package for internationalization of Haskell programs, which now
   supports distribution and installation of PO files.

   Buster 0.99.1, a library for application orchestration that is not FRP.
   Jeff Heard [4]announced the release of [5]Buster, an FRP-like framework
   for constructing reactive programs with a bus model.

   Call for Contributions - Haskell Communities and Activities Report, May
   2009 edition. Janis Voigtlaender [6]issued a call for contributions to
   the 16th edition of the [7]Haskell Communities & Activities Report. The
   submission deadline is 1 May 2009. If you are working on any project
   that is in some way related to Haskell, please write a short entry and
   submit it. Even if the project is very small or unfinished or you think
   it is not important enough -- please reconsider and submit an entry

   fad 1.0 -- Forward Automatic Differentiation library. Bjorn Buckwalter
   [8]announced the initial release of the Haskell [9]fad library,
   developed by Barak A. Pearlmutter and Jeffrey Mark Siskind. Fad
   provides Forward Automatic Differentiation (AD) for functions
   polymorphic over instances of 'Num'.

   hledger 0.4 released. Simon Michael [10]announced the release of
   [11]hledger 0.4, a text-mode double-entry accounting tool. It reads a
   plain text journal file describing your transactions and generates
   precise activity and balance reports. Changes include the ability to
   serve reports in a web browser, and many other fixes and improvements.

   GHC version 6.10.2. Ian Lynagh [12]announced a new patchlevel release
   of [13]GHC. This release contains a number of bugfixes relative to
   6.10.1, including some performance fixes; see the [14]release notes.

   Beta of Leksah IDE available. Jürgen Nicklisch-Franken [15]announced
   release 0.4.4 of [16]Leksah, the Haskell IDE written in Haskell.
   Current features include on the fly error reporting with location of
   compilation errors, completion , import helper for constructing import
   statements, module browser with navigation to definition, project
   management support based on Cabal with a visual editor, "source candy",
   and more.

   satchmo: monadic SAT encoding library. Johannes Waldmann [17]announced
   a preliminary version of [18]satchmo, a monadic library for encoding
   boolean and integral number constraints to CNF-SAT. It uses [19]minisat
   as a backend solver.

   vacuum-cairo: a cairo frontend to vacuum for live Haskell data
   visualization. Don Stewart [20]announced the release of
   [21]vacuum-cairo, a Haskell library for interactive rendering and
   display of values on the GHC heap using Matt Morrow's vacuum library.
   This library takes vacuum's output, generates dot graph format from it,
   renders it to SVG with graphviz, and displays the resulting structure
   using the gtk2hs Cairo vector graphics bindings ... all at the GHCi
   command line. Watch some [22]screencasts!

   vacuum: extract graph representations of ghc heap values.. Matt Morrow
   [23]announced the release of [24]vacuum, a library for extracting graph
   representations of values from the GHC heap, which may then be further
   processed and/or translated to Graphviz dot format to be visualized.

   new release of HTTP, version 4000.0.5. Sigbjorn Finne [25]announced a
   [26]new version of the HTTP package, which includes a bunch of fixes
   and cleanups along with some API documentation.

   type-level programming support library. spoon [27]asked for feedback on
   a [28]support library for type level programming.

   cmonad 0.1.1. Lennart Augustsson [29]announced the [30]CMonad package,
   which allows one to write Haskell code in a C style.

   Marketing Haskell. Ketil "Simon Peyton-Jones" Malde [31]announced the
   new [32]official Haskell mascot.

   Haskell Platform: status update and call for volunteers. Duncan Coutts
   gave an [33]update on the status of the [34]Haskell Platform. There are
   no more policy questions to resolve for the first release. It is a
   matter of getting things done. The first platform release will contain
   ghc-6.10.2, the "extra libs", haddock, happy and alex, and the cabal
   command line tool and it's dependencies. We are calling for volunteers
   for an action group. We need volunteers to take charge of various
   platforms and to manage the overall release. See Duncan's email for a
   list of what is needed, and volunteer!

Quotes of the Week

     * mstr: haskell is like f'gg'fggf'fg'g'fg'foldliftM2 f g ''f' :)
     * simonmar: Wondering how popular Haskell needs to become for intel
       to optimize their processors for my runtime, rather than the other
       way around
     * quicksilver: [about uninstalling packages installed with
       cabal-install] packages are for life, not just for christmas.
     * Ethereal: If this conversation had been had in #python #ruby or
       #php it would have lots of angry people shouting about how it
       doesn't matter or isn't true or isn't important and what's the
       point, and no, you guys are like ahhh but no, your preconceived
       notions of dimensional space are so passe.
     * Duqicnk: a monad is like a train that runs backwards in time, which
       is made of tiny chocolate robots
     * jfredett: I do all of my version numbers in Roman Numerals...
     * Cale: But in another sense, functional programmers are applied
       logicians who spend all their time proving trivial theorems in
       interesting ways in an inconsistent intuitionist logic.
