Haskell Weekly News
Issue 119 - May 23, 2009

   Welcome to issue 119 of HWN, a newsletter covering developments in the
   [1]Haskell community.


   GHC porting works again. Ian Lynagh [2]announced that the
   [3]instructions for porting GHC to a new architecture now work again
   with the HEAD. If you get stuck when trying to do a port, feel free to
   ask on cvs-ghc at haskell.org or in #ghc on freenode.

   6.10.4 plans. Ian Lynagh [4]announced plans for a 6.10.4 bugfix release
   of GHC. If you know of any bugs that you think should be looked into
   for 6.10.4, please let the development team know.

   The Timber compiler 1.0.3. Johan Nordlander [5]announced the release of
   version 1.0.3 of the Timber compiler. Timber is a modern language for
   building event-driven systems, based around the notion of reactive
   objects. It is also a purely functional language derived from Haskell,
   although with a strict evaluation semantics. 1.0.3 is a bug fix
   release, paving the way for future feature releases.

   mathlink- Tracy Wadleigh [6]announced the release of
   [7]mathlink, a library for writing Mathematica packages in Haskell. One
   simply writes some functions of type (MLGet a, MLPut b) => a -> IO b
   and provides a package specification in a simple DSL; the result is a
   program that exposes functions that can be called from Mathematica.

   text 0.2, fast and comprehensive Unicode support using stream fusion.
   Bryan O'Sullivan [8]announced the availability of [9]text 0.2, an
   efficient Unicode text library that uses stream fusion. New and notable
   in this release is support for lazy, chunked text, so you can process
   text files far larger than memory using a small footprint.

   Haskell Hackathon in Philadelphia. Brent Yorgey [10]announced Hac phi,
   a Haskell hackathon to be held in Philadelphia in July. Check out the
   [11]wiki page and add your name if you are interested in attending!
   More details to follow soon.

   feed2twitter 0.2 & hackage2twitter 0.2.1. Tom Lokhorst [12]announced
   the first release of [13]feed2twitter, a library for sending posts from
   a news feed to Twitter.

   EsotericBot 0.0.1. spoon [14]announced the release of [15]Esotericbot,
   a sophisticated, lightweight IRC bot, written in Haskell.

   atom 0.0.4. Tom Hawkins [16]announced a new release of [17]atom; this
   version adds an array datatype (A a).

   Hieroglyph-2.21 and buster, buster-gtk, and buster-network-2.0. Jeff
   Heard [18]announced new releases of [19]Hieroglyph, [20]buster,
   [21]buster-gtk, and [22]buster-network, with tons of changes; read
   Jeff's original announcement for details.

   TxtSushi 0.1. Keith Sheppard [23]announced the first version of
   [24]TxtSushi, a collection of command line utilities for processing
   tab-delimited and CSV files. It includes a utility for doing SQL
   SELECTs on flat files.


   Should exhaustiveness testing be on by default? Don Stewart started a
   [25]discussion, prompted by a [26]recent blog post, on whether coverage
   checking should be on by default, and other issues relating to compiler
   warnings and coding style.

   Proposal on the platform API policy question. Duncan Coutts
   [27]proposed a general policy for Haskell Platform release cycles and
   versioning, based on input from previous discussions.

   the problem of design by negation. Michael Mossey began a
   [28]discussion on software design philosophies. "Design by negation"
   considered harmful?

   Haskell in 3 Slides. John Van Enk [29]asked for ideas on a 3 to 4 slide
   introduction to Haskell. What do YOU think should be on those slides?

     * Will Donnelly: monads are okay after a bit (though I'm still a
       little suspicious of them)
