Haskell Weekly News
Issue 80 - August 6, 2008
Welcome to issue 80 of HWN, a newsletter covering developments in the
Brent Yorgey (byorgey, your friendly neighborhood HWN editor) has
completed a move to Philadelphia and looks forward to starting a PhD in
the programming languages group at U Penn next month.
Roman Cheplyaka (Feuerbach) won second prize at the 2008
International Mathematics Competition!
prof2dot, version 0.4.1. Gregory Wright announced the release of
prof2dot, a graphical profiling tool for use with GHC. prof2dot is a
filter that takes the profiling output generated by running a
GHC-compiled program with the "+RTS -pix -RTS", option and turns it
into a graphviz dot file.
GHC switching to git. Simon Marlow announced that the GHC team has
made the decision to switch the version control system hosting the GHC
repository from darcs to git.
Haddock 2.2.1. David Waern announced the release of version 2.2.1 of
Haddock, the Haskell documentation tool.
Haskore tutorial. jinjing is creating a Haskore tutorial while
learning it. Suggestions and corrections are welcome.
Hoogle 4 beta. Neil Mitchell announced the availability of beta
versions of Hoogle 4, both a web client and command-line version.
Testing and feedback welcome!
Design your own xmonad shirt. David Lazar has prepared a design on
spreadshirt under Designs > Computer > Programming. Choose the
color and other formatting and get your very own custom xmonad shirt!
Google Summer of Code
Progress updates from participants in the 2008 Google Summer of
Generic tries. Jamie Brandon is working on a library for efficient maps
using generalized tries. This week, he has worked on implementing AVL
trees and has created several more benchmarks.
Hoogle 4. Neil Mitchell (ndm) is working on Hoogle 4. This
week, he finished up type search, which now gives much better results
than Hoogle 3. He also released a public beta version of the
command-line interface. Bug reports or feature requests are
DPH physics engine. Roman Cheplyaka (Feuerbach) is working on a
physics engine using Data Parallel Haskell. Last week, he
won second prize at the 2008 International Mathematics Competition;
while he was away he also found time to read several papers on broad
phase collision detection and to begin thinking about general
GHC plugins. Max Bolingbroke is working on dynamically loaded plugins
Cabal dependency framework. Andrea Vezzosi (Saizan) is working on a
make-like dependency analysis framework for Cabal.
Language.C. Benedikt Huber (visq) is working on Language.C, a
standalone parser/pretty printer library for C99.
GHC API. Thomas Schilling (nominolo) is working on improvements to
the GHC API.
poll: how can we help you contribute to darcs?. Eric Kow (kowey)
asked how the darcs team could better encourage more people to
contribute, precipitating a long and productive discussion with many
Lectureship in Functional Programming, Nottingham. Graham Hutton
announced an opening for a Lecturer (Assistant Professor) in the
Functional Programming Lab in Nottingham, a recently formed research
group that comprises Thorsten Altenkirch, Graham Hutton, Henrik
Nilsson, four research fellows, and eleven PhD students. Applications
from the Haskell community are encouraged! The closing date for
applications is Friday, 15th August 2008.

Quotes of the Week
* shepheb: don't forget YMCArray
* matthew-_: you know I increasingly think I'm a very bad haskell
programmer - I spend all my time programming at the type level,
which is basically untyped. So I just write untyped programs, that
happen to run at compile time.
* SyntaxNinja: just picture monads as tiny, silly, luminous, and
devious sprites who fly around your haskell code carrying state
from one piece of code to another. I don't think that'll help, but
it can't hurt.
* poetix: Avoiding lambdas is pointless <-- *groan*
* kzm: My program contains a bug. How ungrateful, after all I've done
* sw17ch: FunPtrs do not live up to their name
