Issue 114 - April 17, 2009
---------------------------------------------------------------------------
Welcome to issue 114 of HWN, a newsletter covering developments in the
[1]Haskell community.
The [2]5th Haskell Hackathon is underway in Utrecht! Happy Haskell
hacking! An early HWN this week since I will be traveling this weekend
(but not, unfortunately, to the Hackathon).
Announcements
Reminder: Haskell Communities and Activities Report. Janis Voigtlaender
[3]reminded everyone that the deadline for the [4]May 2009 edition of
the Haskell Communities and Activities Report is only two weeks away.
If you haven't already, please write an entry for your new project, or
update your old entry.
primes. Sebastian Fischer [5]announced the release of the [6]primes
package, which implements lazy wheel sieves for efficient, purely
functional generation of prime numbers in Haskell.
level-monad-0.3. Sebastian Fischer [7]announced version 0.3 of the
package [8]level-monad, which implements breadth-first search directly
as an instance of MonadPlus (without using an intermediate tree
representation). Version 0.3 adds a MonadPlus instance for iterative
deepening inspired by Michael Spivey's paper on [9]Algebras for
combinatorial search.
hgettext 0.1.10. Vasyl Pasternak [10]announced a new release of the
[11]hgettext package, which now has bindings to all gettext functions.
Haskell logo in TeX. Philip Hölzenspies [12]announced a version of the
new [13]Haskell logo design prepared using TikZ, for inclusion in LaTeX
documents.
The Monad.Reader (14) - Call for copy. Wouter Swierstra [14]issued a
call for copy for Issue 14 of [15]The Monad.Reader. The deadline for
submissions is May 15, 2009. Let Wouter know if you intend to submit
something -- the sooner, the better.
time 1.1.2.4. Ashley Yakeley [16]announced the release of [17]time
1.1.2.4, which should now compile on Windows.
Discussion
Code Golf. Sebastian Fischer [18]started a lively round of code golf
with his code for list diagonalization.
Converting IO [XmlTree] to [XmlTree]. rodrigo.bonifacio [19]asked how
to convert an IO [XmlTree] into an [XmlTree], leading to a discussion of
Haskell pedagogy.
