Issue 136 - October 24, 2009
---------------------------------------------------------------------------
   Welcome to issue 136 of HWN, a newsletter covering developments in the
   [1]Haskell community.

   Short one this week, I have GREs today, so I've spent more time
   aggregating GRE knowledge rather than Haskell news. Till next week,
   Haskellers, The Haskell Weekly News!

Announcements

   PastePipe -- a CLI for hpaste instances. Rogan Creswick [2]announced a
   new version of PastePipe, a library which reads from stdin and posts it
   to an hpaste instance (defaulting to hpaste.org)

   haskell-src-exts-1.2.0. Niklas Broberg [3]announced a major release of
   haskell-src-exts. Several breaking changes, a few (ideally) backwards
   compatable changes. See the post for all the details.

   mecha-0.0.0. Tom Hawkins [4]announced a very cool new DSL in Haskell
   for Constructive Solid Modelling.

   GPipe 1.02 and Vec-Transform 1.0.1. Tobias Bexelius [5]announced new
   versions of these packages, only a few API changes

   Data.Stream 0.4. Wouter Swierstra [6]announced a very delicate change
   to Data.Stream involving irrefutable patterns. Specifically added them
   in functions which produce new streams from old.

   strptime bindings. Eugene Kirpichov [7]announced bindings to strptime.

   cereal-0.2. Trevor Elliott [8]announced a new version of the cereal
   library, a variation on the `binary` package which provides strict
   parsing.

   quickcheck-poly. Ki Yung Ahn [9]announced a package for testing
   polymorphic functions automatically.

   2nd CFP: JSC Special Issue on Automated Verification and Specification
   of Web Systems. demis [10]announced a special issue of the Journal of
   Symbolic Computation. The issue contains articles relating to Automated
   Specification and Verification of Web Systems.

   qtHaskell-1.1.3. David Harley [11]announced a new version of qtHaskell.

Discussion

   Is there in Haskell the eval function? Waldemar Biernacki [12]asked
   about an `eval` function for Haskell.

   What's this pattern called? Martijn van Steenbergen [13]asked about a
   common pattern for an simple EDSL AST-like type.

   Problems with Haskell. Philippos Apolinarius [14]forwarded his response
   to a [15]Clean programmer who planned a move to Haskell upon fears of
   Clean being around for the long term. A very nice read.

   Statically checked binomail heaps? Maciej Kotowicz [16]talked about his
   implementation of Statically Checked Binomial Heaps in Haskell

Quotes of the Week

     * Veinor: I program in austere haskell. I name all my variables a,
       a', a'', a''', etc
     * ddarius: releases network version 127.0.0.1
     * Berengal: 'Bobby Boolean felt horrible. What did he ever do to the
       other values? He was just a simple bit, a simple answer to a simple
       question! Suddenly he felt his insides churn; he felt an exception
       coming on! Oh no! What should he do, now that he was outside of
       IO?'
     * Berengal: '"Go away! You're not like us!" the other values yelled.
       "You're impure! Impure! Impure! Impure!" they started chanting.'
     * dpratt71: <dpratt71> so I read somewhere that the unofficial motto
       of Haskell was "avoid success at all costs"... <Baughn> dpratt71:
       Yeah. We failed.
     * Warrigal: Note to self: don't do maximum [1..].
     * mauke: the first and foremost task of a haskell compiler is to
       break haskell programs
     * ksf: ...premature generalisation is the root of all
       procrastination.
     * jimi_hendrix: that took longer than it should have, but it feels so
       pure
     * ddarius: Unfortunately, the logic programming community has this
       unhealthy death grip on Prolog.
