Issue 81 - August 13, 2008
---------------------------------------------------------------------------
Welcome to issue 81 of HWN, a newsletter covering developments in the
[1]Haskell community.
This week saw some interesting talks at [2]AngloHaskell, and some cool
new packages to hit Hackage, like [3]Language.C, [4]AERN-Real, [5]FTGL,
and [6]Hoogle. What are you waiting for? Get out there and build
something!
Announcements
Initial release of Language.C (language-c-0.3). Benedikt Huber
[7]announced the [8]first release of [9]Language.C, a library for
analysing and generating C code. This release features a reasonably
well tested parser, a pretty printer, and a preview of the analysis
framework.
darcs roadmap. Jason Dagit [10]wrote to the list to thank everyone for
their support for darcs, and to announce a webpage with a [11]roadmap
for future darcs features. Darcs is alive and well!
Anglo Haskell 2008 -- slides and audio. Matthew Sackman [12]announced
that [13]slides and audio from Anglo Haskell 2008 are now available.
BLAS bindings for haskell, version 0.5. Patrick Perry [14]announced a
new release of the Haskell BLAS bindings, including a number of new
features and improvements.
Tutorial on information visualization and visual analytics in Haskell.
Jefferson Heard [15]announced the [16]tutorial he will be presenting at
DEFUN 2008, to give everyone a sneak peek at the long version of the
tutorial before he's done with it. Comments and questions are welcome
and encouraged.
interval and polynomial enclosure arithmetics. Michal Konecny
[17]announced the release of the [18]AERN-Real and [19]AERN-RnToRm
packages, which model and reasonably efficiently implement exact real
arithmetic.
FTGL 1.0. Portable truetype font rendering in OpenGL. Jefferson Heard
[20]announced the release of [21]Haskell bindings to FTGL, an easy to
use library for portable rendering of TrueType fonts in OpenGL.
Google Summer of Code
Progress updates from participants in the 2008 [22]Google Summer of
Code.
GHC plugins. Max Bolingbroke is working on dynamically loaded plugins
for GHC. [23]This week, he gave [24]a talk at AngloHaskell.
Language.C. Benedikt Huber (visq) is [25]working on Language.C, a
standalone parser/pretty printer library for C99. This week, he
[26]announced the [27]first release of the [28]Language.C package.
Hoogle 4. Neil Mitchell (ndm) is working on [29]Hoogle 4. [30]This
week, he released several [31]command-line versions and a [32]web
version of Hoogle 4, updated the manual, and gave [33]a talk at
AngloHaskell. Next week, he plans to work on generating better Hoogle
databases, and some bug fixes.
DPH physics engine. Roman Cheplyaka (Feuerbach) is working on a
[34]physics engine using [35]Data Parallel Haskell. [36]This week, he
added complete support for general polyhedra, and fixed some bugs in
the collision handler. He also added support for bounding spheres,
although the results so far are disappointing, due to delays in the GHC
implementation of parallel arrays. Next week, he plans to implement
static bodies and BSP trees.
Generic tries. Jamie Brandon is working on a library for efficient maps
using generalized tries.
GHC API. Thomas Schilling (nominolo) is working on [37]improvements to
the GHC API.
Cabal dependency framework. Andrea Vezzosi (Saizan) is working on a
[38]make-like dependency analysis framework for Cabal.
