   Welcome to issue 159 of the HWN, a newsletter covering developments in
   the [1]Haskell community in the week of November 07 - 13.

   We have a new GHC to celebrate! On November 16 the GHC team announced
   the [2]release of GHC 7.0.1. Plenty of goodness here, with many bug
   fixes and numerous performance improvements over the previous 6.12
   branch. The good folks at GHC remind us that most users should
   countinue to use the Haskell Platform. This "release is aimed primarily
   at package maintainers and early adopters." Many kudos to the team!

   Curious about the most active members of the #haskell IRC channel? Out
   of around 28K "utterances" in the channel this week, 24% of them where
   spoken by the top 5 most active members. Not suprisingly, the dear
   lambdabot is at the top of the list.

   	     lambdabot              2094
	     kmc                      1263
	     jmcarthur               1221
	     Eduard_Munteanu  1142
	     EvanR-work           1007

   This week we had 299 messages posted to Haskell-Cafe (down 79 from last
   week), 26 stories posted to Reddit (4 less than last week), 36
   questions posted to StackOverflow (4 less than last week), and 135
   updates to Hackage (39 more than last week). Fun to see the different
   package maintainers upgrading their packages to the new GHC.


   Simon Meier uploaded [3]blaze-builder, a library which provides an
   abstraction of buffered output of byte streams and several convenience
   functions to exploit it. He notes that blaze-builder was inspired by
   the Data.Binary.Builder module.

   David Peixotto introduced the [4]Fibon benchmark tools and suite for
   running and analyzing programs. It includes an optional set of
   benchmark programs, including many taken from Hackage.

   Tom Lokhorst uploaded [5]language-cil, a library for manipulating
   Common Intermediate Language, the lowest level language used by
   Microsoft .NET and Mono.

   Janis Voigtländer announced that the [6]Haskell Communities and
   Activities Report is now available in both PDF and HTML format. Check
   it out and see what others in the community are doing. The list of
   contributors should be enough to convince you to read it!

Quotes of the week

     * hpc: (<$>) = fmap; (<*>) = magic
     * medfly: it's awesome not to be an expert here. you ask questions
       that you think are difficult and they are so easy to others that
       they are all excited to explain it to you.
     * EvanR: think of [grant applications] as the interface to the real
       world, like the IO monad
     * ray: every paul graham essay contains an ad-hoc, informally
       specified implementation of a good idea
