--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20090207 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.

Do you use Haskell on the job?
by kirk.martinez＠gmail.com 07 Feb '09

07 Feb '09

Hello, fellow Haskell hackers! I am writing a term paper on Haskell in Business, and while I have gathered a lot of good information on the Internet, I would really like direct feedback from software professionals who have used Haskell in a business setting. I would really appreciate a few minutes of your time to provide insights gained from applying Haskell in the real world. Who knows, this could lead to a greater adoption of Haskell in the business community! Rather than a list of Haskell's technical strengths (purity, laziness, composition, etc.), I want to get a sense of the process leading up to the decision to use Haskell for a given project and the insights gained during and after completion. I am particularly interested in questions related to business value: * What were the pros and cons you considered when choosing a language? Why FP? Why Haskell? * What aspects of your problem domain were most critical to making that choice? * How has using Haskell given you a competitive advantage? * How is the software development lifecycle positively/negatively affected by using Haskell as opposed to a different language? * How did you convince management to go with a functional approach? * Was the relative scarcity of Haskell programmers a problem? If so, how was it managed? * Would you choose to use Haskell again for a similar project given what you know now? The best responses will not simply list answers, but also provide background and a bit of narrative on the project and insights gained. Feel free to reply to the list, or just to me personally if you prefer. My email is below. Thank you, Kirk Martinez (Kirk dot Martinez at gmail dot com)

Re: Haskell Digest, Vol 63, Issue 8

06 Feb '09

Simon PJ's interview in Computer World about Haskell: http://www.computerworld.com.au/index.php/id;1974033854 > contains the following quote: "IO is a side effect as we discussed. IO ensures the launching of the missiles: do it now and do it in this order. IO means that it needs to be done in a particular order, so you say do this and then do that and you are mutating the state of the world." I couldn't help enjoying the following abbreviation: "IO ensures the launching of the missiles ... and you are mutating the state of the world." :-) Nikhil PS: Also, "oh, that's not very cool, how can we launch missiles with that?"

Call for Papers: 2nd International Conference on Software Language Engineering
by Serebrenik, A. 04 Feb '09

04 Feb '09

___________________________________________________________________ Call for Papers - SLE 2009 2nd International Conference on Software Language Engineering http://planet-sl.org/sle2009 Denver, Colorado, October 5-6, 2009 ___________________________________________________________________ Co-located with 12th International Conference on Model-Driven Engineering Languages and Systems (MODELS 2009) and 8th International Conference on Generative Programming and Component Engineering (GPCE 2009) Proceedings will be published in the LNCS series (subject to Springer's approval). The 2nd International Conference on Software Language Engineering (SLE) is devoted to topics related to artificial languages in software engineering. SLE's foremost mission is to encourage and organize communication between communities that have traditionally looked at software languages from different, more specialized, and yet complementary perspectives. SLE emphasizes the fundamental notion of languages as opposed to any realization in specific "technical spaces". SLE 2009 will be co-located with the 12th IEEE/ACM International Conference on Model-Driven Engineering Languages and Systems (MODELS 2009). Scope ----- The term 'software language' comprises all sorts of artificial languages used in software development including general-purpose programming languages, domain-specific languages, modeling and meta-modeling languages, data models, and ontologies. Used in its broadest sense, examples include modeling languages such as UML-based and domain-specific modeling languages, business process modeling languages, and web application modeling languages. The term 'software language' also comprises APIs and collections of design patterns that are implicitly defined languages. Software language engineering is the application of a systematic, disciplined, quantifiable approach to the development, use, and maintenance of these languages. Thus, the SLE conference is concerned with all phases of the life cycle of software languages; these include the design, implementation, documentation, testing, deployment, evolution, recovery, and retirement of languages. Of special interest are tools, techniques, methods and formalisms that support these activities. In particular, tools are often based on or even automatically generated from a formal description of the language. Hence, of special interest is the treatment of language descriptions as software artifacts, akin to programs - while paying attention to the special status of language descriptions, subject to tailored engineering principles and methods for modularization, refactoring, refinement, composition, versioning, co-evolution, and analysis. Topics of interest ------------------ We solicit high-quality contributions in the area of SLE ranging from theoretical and conceptual contributions to tools, techniques and frameworks that support the aforementioned life cycle activities. Some examples of tools, techniques, applications, and problems are listed below in order to clarify the types of contributions sought by SLE. * Formalisms used in designing and specifying languages and tools that analyze such language descriptions. * Language implementation techniques, grammar-based and metamodel-based. * Program and model transformation tools. * Composition, integration, and mapping tools for managing different aspects of software languages or different manifestations of a given language. * Language evolution. * Approaches to the elicitation, specification, and verification of requirements for software languages. * Language development frameworks, methodologies, techniques, best practices, and tools for the broader language life cycle covering phases such as analysis, testing, and documentation. * Design challenges in SLE. * Applications of languages including innovative domain-specific languages or "little" languages Do note that this list is not exclusive and many examples of tools, techniques, approaches have not been listed. Please visit the conference web site to see a more elaborate description of the topics of interests. The program committee chairs encourage potential contributors to contact them with questions about the scope and topics of interest of SLE. Paper Submission ---------------- We solicit the following types of papers: * Research papers. These should report a substantial research contribution to SLE and/or successful application of SLE techniques. Full paper submissions must not exceed 20 pages. * Short papers. These may describe interesting or thought-provoking concepts that are not yet fully developed or evaluated, make an initial contribution to challenging research issues in SLE, or discuss and analyze controversial issues in the field. These papers must not exceed 10 pages. * Tool demonstration papers. Because of SLE's ample interest in tools, we seek papers that present software tools related to the field of SLE. These papers will accompany a tool demonstration to be given at the conference. These papers must not exceed 10 pages. The selection criteria include the originality of the tool, its innovative aspects, the relevance of the tool to SLE, and the maturity of the tool. Submissions may also include an appendix (that will not be published) containing additional screen-shots and discussion of the proposed demonstration. * Mini-tutorial papers. SLE is composed of various research areas, such as grammarware, modelware, language schemas, and semantic technologies. The cross product of attendees at SLE creates a situation where the contribution from one session may be difficult to understand by those not initiated to the area. To help unite the various communitues of SLE 2009, mini-tutorials are solicited that provide discussion points for mapping common ideas between the area and differentiating among variations. A mini-tutorial submisson should be between 15 and 20 pages. Submitted articles must not have been previously published or currently be submitted for publication elsewhere. All submitted papers will be closely reviewed by at least three members of the program committee. All accepted papers will be made available at the conference in the pre-proceedings and published in the post-proceedings of the conference, which will appear in Springer's Lecture Notes in Computer Science series. Authors will have the opportunity to revise their accepted paper for the pre- and post-proceedings.
