Haskell Weekly News
Issue 97 - December 13, 2008

   Welcome to issue 97 of HWN, a newsletter covering developments in the
   [1]Haskell community.

   Lots of neat blog posts and funny quotes this week. Don't forget to
   keep adding [2]haiku to the wiki, and don't miss Alex McLean (yaxu)'s
   [3]streaming livecoding performance tonight!


   Spam on HaskellWiki. Ashley Yakeley [4]asked what people would like to
   do about the increasing amounts of spam on the Haskell wiki, and
   offered some suggestions.

   The Timber compiler 1.0.2. Johan Nordlander [5]announced the first
   public release of the [6]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. To try it out, just grab
   the [7]timberc package on Hackage.

   Retrospective on 2008?. Don Stewart [8]proposed the idea of a 2008
   retrospective. How would you choose the 10 best new libraries,
   applications, blog posts, etc. of 2008?

   a haskell_proposals subreddit. Jason Dusek [9]announced a [10]subreddit
   for Haskell library proposals. The idea is that Web 2.0 will help us to
   allocate our collective talents more efficiently when it comes to
   extensions (and perhaps clue us in when our pet project is something
   people really want).

   permutation-0.2. Patrick Perry [11]announced a [12]new version of the
   permutation library, which includes data types for storing
   permutations. It implements pure and impure types, the latter which can
   be modified in-place. The main utility of the library is converting
   between the linear representation of a permutation to a sequence of
   swaps. This allows, for instance, applying a permutation or its inverse
   to an array with O(1) memory use.

   Data.List.Split. Brent Yorgey [13]announced the creation of a wiki page
   for [14]Data.List.Split, a hypothetical module containing
   implementations of every conceivable way of splitting lists known to
   man, so we no longer have to (1) argue about the 'one true' interface
   for a 'split' function, or (2) be embarrassed when people ask why there
   isn't a split function in the standard libraries. Please add code or
   comments! At some point it will be uploaded as a new module to Hackage.

   Announcing Haskell protocol-buffers version 1.2.2. Chris Kuklewicz
   [15]announced new versions of [16]protocol-buffers,
   [17]protocol-buffers-descriptor, and [18]hprotoc.


   A curious monad. Andrew Coppin [19]exhibited an interesting Storage
   monad, which (it turns out) is similar to ST. An enlightening
   discussion if you want to understand how ST works and the motivation
   behind it.

   Origins of '$'. George Pollard [20]asked about the origins of the $
   operator (low-precedence function application) in the standard
   libraries, leading to some interesting history and general discussion
   about notation.
