--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20100308 Issue 152 - March 08, 2010 --------------------------------------------------------------------------- Welcome to issue 152 of HWN, a newsletter covering developments in the [1]Haskell community. Hello Haskellers, this week brings updates to some standards (like Parsec), as well as some new tunes to the Haskell songbook. WAI and Yesod were released, giving some new options for Haskell-based web applications, Don Stewart made some improvements to his Genetic Optimizer system to include options from GHC's new LLVM backend, and I made some serious progress on the new HWN software. Speaking of the new software, there have been numerous reports of warts and other unfortunate things with the current editions of the HWN. Fear not, these warts are well known and being worked on intently. Unfortunately, it's somewhat difficult to fix them given the current publication software, however, in the new-and-improved version that (hopefully) should be entering use soon, these warts will be removed. So, without further interuption about the stylistic content, Haskellers, your Haskell Weekly News! Announcements Bluetile 0.3.1. Jan Vornberger [2]announced Bluetile, an adaptation of xmonad for the masses. Bluetile aims to make tiling window managers accessible by drawing on standard window manager conventions and idioms. ED: This is not technically an announcement, but it's very cool and everyone should check it out! yesod 0.0.0 (web framework). Michael Snoyman [3]announced the release of yesod, a web framework based on WAI. wai-0.0.0 (Web Application Interface). Michael Snoyman [4]announced the first release of wai, a library implementing the WAI protocol. iteratee-parsec 0.0.2. Maciej Piechotka [5]announced iteratee-parsec, a library which allows for parsec parsers in the IterateeG monad. Parsec 3.1.0. Derek Elkins [6]announced a new release of Parsec, containing many improvments due (primarily) to Antoine Latter. Progression-0.3 (supporting benchmarking in Haskell). Neil Brown [7]announced a new release of Progression. Progression is a utility built on top of Criterion for recording benchmarks for several version of your code. Ghent Functional Programming Group: First Meeting on April 1, 2010. Jeroen Janssen [8]announced the first meeting of the Ghent Functional Programming group, see the post for location and time details. PhD position in Functional Programming at Chalmers (deadline 2010-04-07). Patrik Jansson [9]announced an opening for a PhD student at Chalmers, working in Functional Programming and DSELs. VSTTE 2010: Verified Software -- Third Call for Papers. Gudmund Grov [10]announced a third CFP for VSTTE 2010, the Third International Conference on Verified Software: Theories, Tools, and Experiments. barchart-0.1.1. Sebastian Fischer [11]announced barchart, a command line program with an associated library for generating bar charts. Call for Participation: CHR Summer School. Jon Sneyers [12]announced a call for participation in the CHR Summer School on Programming and Reasoning with Rules and Constraints. Discussion Free theorem - what do we need it for. Maciej Piechotka [13]asked about Free Theorems and what they were good for. Has anybody translated Douglas Hofstadter's Scientific American articles introducting Scheme to a general audience into Haskell? Benjamin L. Russell [14]asked if anyone had considered translating Douglas Hofstadter's SciAm articles introducting Scheme to Haskell. Evolving Faster Haskell Programs (now with LLVM!). Don Stewart [15]our resident speed demon is at it again, harnessing the new LLVM backend of GHC and the power of Natural Selection to make his programs go even faster.
