[http://article.gmane.org/gmane.comp.lang.haskell.cafe/20232 announced] that Haskell.org has once again applied to be a mentoring organisation for the Google Summer of Code. If you are a student who would like to earn money hacking in Haskell, or you are a non-student who has a cool idea for a coding project but no time to do it yourself, then visit the [http://hackage.haskell.org/trac/summer-of-code SoC wiki] to gather ideas, and add yourself to the list of interested people! Add new ideas for projects!</p></li>

[http://article.gmane.org/gmane.comp.lang.haskell.general/15006 announced] the first release of [http://haskell.org/haskellwiki/GHC/Data_Parallel_Haskell the NDP package], a library for writing nested data-parallel programs in Haskell, on shared-memory multiprocessors. The NDP library is part of the Data Parallel Haskell project. The paper [http://www.cse.unsw.edu.au/~chak/papers/CLPKM07.html Data Parallel Haskell: a status report] describes the underlying design and go through an example program.</p></li>

[http://article.gmane.org/gmane.comp.lang.haskell.general/14977 announced] the initial call for papers for the Haskell Workshop 2007, part of the 2007 International Conference on Functional Programming (ICFP).

[http://article.gmane.org/gmane.comp.lang.haskell.general/15028 announced] the [http://www.wellquite.org/chunks Text.HTML.Chunks] library, a clone with improvements of the Perl HTML::Chunks module. The main achievement is the use of template-haskell to combine the template into the code at compile time. This then allows for static checking that the variables/fields that the templates are expecting are indeed being provided and that the templates the code is trying to use do indeed exist. The template is then incorporated within the code, removing the dependency on the template.</p></li>

The library supports addition/subtraction, predecessor/successor, multiplication/division, exp2, full comparisons, GCD, and the maximum. At the core of the library are multi-mode ternary relations Add and Mul where any two arguments determine the third. Such relations are especially suitable for specifying static arithmetic constraints on computations. The type-level numerals have no run-time representation; correspondingly, all arithmetic operations are done at compile time and have no effect on run-time.</p></li></ul>

The HTML does not have to be well formed, or render properly within any particular framework. This library is for situations where the author of the HTML is not cooperating with the person trying to extract the information, but is also not trying to hide the information.
