Issue 104 - February 07, 2009
---------------------------------------------------------------------------
Welcome to issue 104 of HWN, a newsletter covering developments in the
[1]Haskell community.
Community News
Andre Pang (ozone) will be soon [2]moving to San Fransisco to begin
work with [3]Pixar!
Announcements
Mutually recursive modules. Henning Thielemann [4]announced a [5]small
writeup explaining how mutually recursive modules are currently
supported, and how they can be avoided. Please add information about
other compilers and more ideas on breaking cycles.
UrlDisp, a friendly URL dispatching library. Artyom Shalkhakov
[6]announced the first release of [7]UrlDisp, a small library for URL
dispatching (aka routing). Right now it works with CGI, and should be
compatible with FastCGI as well (not tested); Happstack compatibility
is planned. [8]Documentation and usage examples are available.
Purely functional LU decomposition. Rafael Gustavo da Cunha Pereira
Pinto [9]released some code to perform purely functional LU
decomposition.
Ready for testing: Unicode support for Handle I/O. Simon Marlow
[10]announced that proper Unicode support in Handle I/O is ready for
testing in GHC. Just download the [11]set of patches, compile GHC with
them, and test away! Comments and discussion welcome.
HaskellWiki Accounts. Ashley Yakeley can [12]create a HaskellWiki
account for anyone who wants one (account creation has been disabled as
a spam-fighting measure).
multiplicity 0.1.0 released. Dino Morelli [13]announced the release of
[14]multiplicity 0.1.0, a configuration file driven wrapper around
[15]duplicity. It allows you to easily define backup sets as config
files and avoid long, repetitive command lines.
Happstack 0.1 Released!. Matthew Elder [16]announced the [17]0.1
release of [18]Happstack, the successor for the HAppS project.
#haskell-in-depth IRC channel. Philippa Cowderoy [19]announced the
creation of a new IRC channel, #haskell-in-depth. The new channel is
open to everyone, just like #haskell, but is intended for more in-depth
conversations, to allow the #haskell channel to be a more
newbie-friendly place.
regex-posix-unittest-1.0 AND regex-posix-0.94.1 AND regex-tdfa-0.97.1.
ChrisK [20]announced an update to the [21]regex-posix package which
provides better semantics for multiple matches; an update to the
[22]regex-tdfa package, which provides the same new multiple match
semantics and fixes a bug; and finally, a new package,
[23]regex-posix-unittest, along with an [24]accompanying wiki page; it
runs a suite of unit tests which regex-tdfa passes, but reveals bugs in
the standard glibc, OS X, FreeBSD, and NetBSD implementations!
Jane Street Summer Project 2009. Yaron Minsky [25]announced the
[26]Jane Street Summer Project for 2009, the goal of which is to make
functional programming languages into better practical tools for
programming in the real world. Students will be funded over the summer
to work on open-source projects which aim at improving the practical
utility of their favorite functional language.
gitit 0.5.1. John MacFarlane [27]announced the release of [28]gitit
0.5.1, a wiki program that uses git or darcs as a filestore and HAppS
as a server. Changes include major code reorganization, bug fixes, new
debugging features, and more.
regex-xmlschema. Uwe Schmidt [29]announced the [30]release of
[31]regex-xmlschema, (yet another) package for processing text with
regular expressions, containing a complete implementation of the W3C
XML Schema specification language for regular expressions.
diagrams 0.2. Brent Yorgey [32]announced version 0.2 of the
[33]diagrams package, an embedded domain-specific language for creating
simple graphics in a compositional style. New features include support
for arbitrary paths, text, multiple output formats, and support for the
[34]colour library.
Discussion
Haddock Markup. David Waern began a [35]discussion on Haddock markup
syntax: should it support (La)TeX for embedded mathematics? Should it
support other stuff?
Elegant & powerful replacement for CSS. Conal Elliott began a
[36]discussion on an elegant replacement for CSS that is consistent,
composable, orthogonal, functional, and based on an elegantly
compelling semantic model---what might such a thing look like?
type metaphysics. Gregg Reynolds began a long and interesting
[37]discussion on the type system, denotational semantics, and related
matters.
Jobs
Postdoc Positions at the CLIP group, Spain. CFP [38]announced the
availability of [39]postdoctoral research positions within the [40]CLIP
(Computational Logic, Implementation and Parallelism) group in Madrid,
Spain. The application deadlines are February 13th and 18th; see the
original email for more details.
Multiple funded Ph.D. positions available. Martin Erwig [41]announced
the availability of multiple funded Ph.D. positions in the [42]school
of EECS at Oregon State University, in the areas of programming
languages (focusing on DSLs and language design), software engineering,
and HCI. If you are interested, email Martin with a resume and contact
information by February 15.
