ANNOUNCE: RandProc v0.4 released.

v0.4 of `RandProc` has just been posted to Hackage:
http://hackage.haskell.org/package/randproc

In this release:

      * Examples of using the `RandProc` library to work problems from
        `Random Processes` text have been added.
      * `README` file has been fleshed out a bit.

ANNOUNCE: regex-applicative-0.1

I am glad to announce the initial release of regex-applicative.

Hackage:      http://hackage.haskell.org/package/regex-applicative
Repository:   https://github.com/feuerbach/regex-applicative
Issues:       https://github.com/feuerbach/regex-applicative/issues

regex-applicative is aimed to be an efficient and easy to use parsing combinator
library based on regular expressions.

Perl programmers often use regular expressions for parsing, even if it is not
an appropriate tool for the job, because Perl has so good support for regexps.

The opposite seems to be valid about Haskell programmers -- they use parsing
combinators (which recognize context-free or even context-sensitive grammars),
even when the language is actually regular!

Hopefully, this library will improve the situation.

This is an early preview release. Some features are lacking, and performance is
probably not very good yet.

Among the features that we are going to support in future versions are:

    * Non-greedy operators
    * Search-and-replace functionality
    * Error reporting

The implementation is heavily based on the ideas from "A Play on Regular
Expressions" by Sebastian Fischer, Frank Huch and Thomas Wilke.

Haskell Implementors Workshop 2011, Second CFT

                        Call for Talks
            ACM SIGPLAN Haskell Implementors' Workshop

    http://haskell.org/haskellwiki/HaskellImplementorsWorkshop/2011
                Tokyo, Japan, September 23rd, 2011
      The workshop will be held in conjunction with ICFP 2011
             http://www.icfpconference.org/icfp2011/

Important dates

Proposal Deadline:  22nd July      2011
Notification:        8th August    2011
Workshop:           23rd September 2011

The Haskell Implementors' Workshop is to be held alongside ICFP 2011
this year in Tokyo, Japan. There will be no proceedings; it is an
informal gathering of people involved in the design and development
of Haskell implementations, tools, libraries, and supporting
infrastructure.

This relatively new workshop reflects the growth of the user
community: there is a clear need for a well-supported tool chain for
the development, distribution, deployment, and configuration of
Haskell software.  The aim is for this workshop to give the people
involved with building the infrastructure behind this ecosystem an
opportunity to bat around ideas, share experiences, and ask for
feedback from fellow experts.

We intend the workshop to have an informal and interactive feel, with
a flexible timetable and plenty of room for ad-hoc discussion, demos,

Haskell Weekly News: Issue 189

   Welcome to issue 189 of the HWN, a newsletter covering developments in
   the Haskell community during the week of June 26 to July 2, 2011.

   It seems that it was a pretty quiet week in the mailing list. There
   were no significant announcements made, and the number of threads was
   low by comparison. Hope everyone is having a great week!

   You can find the HTML version at:
   http://contemplatecode.blogspot.com/2011/07/haskell-weekly-news-issue-189.html

Quotes of the Week

   * iwtu: [#haskell] is a good channel. Really. People are helpful and
     don't deserve killing or eating

   * [Cale] Finite dimensional vector spaces over a field F are
     algebras for the monad of F-linear combinations of elements of a
     set.
     [ivanm] oooohhhhh.... _now_ I get you!

   * [quicksilver] C++ templates can embed arbitrary computation at
     compile time
     [quicksilver] that alone tells you something about the
     complexity of the compiler
     [edwardk] yeah. they were accidentally turing complete. (whoops!) ;)
     [quicksilver] edwardk: OOPS I ACCIDENTALLY THE WHOLE TARPIT

   * bos: other companies use expensive firewalls and crypto hardware to
     protect their intellectual secrets. edwardk uses category theory!

SPLST 2011 - Call for Papers

Dear all,

Please consider submitting a short or long paper to this symposium to
be held in Tallinn in October. The symposium is timed to coincide with
the next (more informal) Estonian Theory Days meeting so authors are
welcome to attend both events.  The symposium is local in a linguistic
sense and alternates between Estonia, Finland and Hungary. After the
symposium selected authors will be invited to revise their papers for
a journal special issue published by the Estonian Academy of Sciences.

We would be delighted to see submissions from the Haskell community!

See below for further information.

Regards,

James Chapman

CFP: PADL'12 - Practical Aspects of Declarative Languages 2012

                          ===============

                  14th International Symposium on 
      Practical Aspects of Declarative Languages (PADL 2012)

            http://research.microsoft.com/~crusso/padl12

    Abstract/Paper submission deadline: September 10th/17th, 2011

                       Conference Description
                      ======================

   Declarative languages build on sound theoretical bases to provide attractive frameworks for
application development. These languages have been successfully applied to many different real-world
situations, ranging from data base management to active networks to software engineering to decision
support systems.

   New developments in theory and implementation have opened up new application areas. At the same time,
applications of declarative languages to novel problems raise numerous interesting research issues.
Well-known questions include designing for scalability, language extensions for application
deployment, and programming environments. Thus, applications drive the progress in the theory and
implementation of declarative systems, and benefit from this progress as well.

   PADL is a forum for researchers and practitioners to present original work emphasizing novel

Call for GUI examples - Functional Reactive Programming

Dear Haskellers,

Can GUI programming be liberated from the IO monad? Functional Reactive 
Programming (FRP) promises as much, and I'm trying to make this dream a 
reality with my [reactive-banana][] library. Having released version 
0.4.0.0, I am now looking for example programs to direct the future 
evolution of the library.

Do you know any *small GUI programs* that you would *like* to see 
*implemented with Functional Reactive Programming?*

I'm sure that some of you

* are interested in FRP and would like to learn from a few simple but 
beautiful examples
* or have written small GUI programs that they are unhappy with because 
they were not purely functional
* or have thought about FRP before and concocted a few examples that are 
very tricky to implement with FRP
* or have written a nice little GUI application that simply makes a 
great example.

I would love to hear your examples, so that I can try to convert them to 
FRP style and test my library against them!

Strictly speaking, it doesn't have to be an example with a graphical 
interface, I'm also interested in audio and animation examples, though 
I'm currently focusing on GUIs.

Here a few examples of what I am looking for:

* I think that Tim Docker's minimal step sequencer [hbeat][] simply 
makes a great example. I hope that wxHaskell offers a 
platform-independent way to play sound.

* While editing the [Haskell Weekly News][hwn], Brent Yorgey wrote a 
little command-line [program to gather newsworthy items][zipedit]. But 
wouldn't a GUI be great? Since I'm only interested in the GUI, someone 
would have to supply the feed parser for this example to be viable. 
Maybe the current editor, Daniel Santa Cruz, might be interested?

* Notes of a musical performance can be modeled as event streams (MIDI), 
as Henning Thielemann has [done with great effect][midi streams]. 
Surely, reactive-banana should be up to the task, but writing an 
arpeggiator seems impossible at the moment.
