Issue 106 - February 21, 2009
---------------------------------------------------------------------------
Welcome to issue 106 of HWN, a newsletter covering developments in the
[1]Haskell community.
Announcements
HWEB. Eric Macaulay, following a little [2]prodding by Neil Mitchell,
has released version 0 of [3]HWEB, a small tool for producing literate
Haskell programs.
Cabal-1.6.0.2 and cabal-install-0.6.2. Duncan Coutts [4]announced
point-releases of the Cabal library and the cabal-install command line
tool. These releases include a number of fixes and minor improvements,
and are expected to be included with ghc-6.10.2.
Barrie 0.3.1. Fraser Wilson [5]announced a hackage release of
[6]Barrie, an implementation of an idea for supporting state based,
user-driven GUIs.
Yogurt-0.3. Martijn van Steenbergen [7]announced the release of
[8]Yogurt-0.3, a MUD client library for Haskell. This version improves
over 0.2 in several ways, including support for GHC 6.10, no more
unsafeCoerce needed, new support for forking threads, and various
refactorings.
wxFruit-0.1.2. Henk-Jan van Tuyl [9]announced an [10]update of
[11]wxFruit, a graphical user interface that combines some of the power
and versatility of wxHaskell with the elegance and simplicity of Fruit.
The new version works with GHC 6.10, and also includes a demo game,
PaddleBall. Interested parties, take note: the position of
developer/maintainer for this library is currently open.
Paper draft: "Denotational design with type class morphisms". Conal
Elliott [12]announced a [13]draft of a new paper, "Denotational design
with type class morphisms". Feedback is appreciated, especially if in
time for the March 2 ICFP deadline.
Crypto 4.2.0 & Related News. Creighton Hogg [14]announced the release
of version 4.2.0 of the [15]Crypto library. Creighton will also
betaking over maintenance of the library from Dominic Steinitz.
The Typeclassopedia, and request for feedback. Brent Yorgey
[16]announced a [17]first draft of an article entitled 'The
Typeclassopedia', a "starting point for the student of Haskell wishing
to gain a firm grasp of its standard type classes." Comments and
feedback are encouraged!
hslibsvm-2.88.0.1 - A FFI binding to LibSVM. S. Guenther [18]announced
the [19]hlibsvm package, a set of Haskell bindings to the C++
[20]libsvm library.
spacepart-0.1.0.0 (was called data-spacepart). Corey O'Connor
[21]announced a new release of the [22]spacepart package, supporting
space-partitioning data structures. The new release includes many bug
fixes and some code cleanup.
pqueue-mtl, stateful-mtl. Louis Wasserman [23]announced two new
packages, [24]stateful-mtl and [25]pqueue-mtl. stateful-mtl provides an
ST monad transformer, several useful operations on generic monad
transformers, and a monad transformer intended to cleanly externally
wrap operations on a mutable array (including resizing operations).
pqueue-mtl provides implementations of several structures supporting a
generic 'single-in, single-out' paradigm (encapsulated in a typeclass
named Queuelike), including stacks, queues, and several implementations
of priority queues.
haha-0.1 - Animated ascii lambda. Sebastiaan Visser [26]announced
[27]haha, a very minimal vector based ascii art library written just
for fun. If you've always wanted to have a full-color rotating vector
based ascii art lambda on your terminal, now is your chance!
Discussion
Darcs and Google Summer of Code. Eric Kow [28]floated the idea of
having darcs apply to the Google Summer of Code as a separate mentoring
organization, and discussed several ideas for student projects.
Jobs
Postdoctoral Research Position at Yale University. Paul Hudak
[29]announced the availability of a postdoctoral research position at
Yale University. The successful candidate will apply modern, high-level
programming language ideas (such as embodied in Haskell) to help design
and implement a language for the control of BGP-based network routers,
with the goal of realizing high-level networking protocols for traffic
engineering, security, and related networking concerns.
