Haskell Implementors' Workshop talk proposals due in one week!
by Johan Tibell 09 Jul '12

09 Jul '12

Call for Talks ACM SIGPLAN Haskell Implementors' Workshop http://haskell.org/haskellwiki/HaskellImplementorsWorkshop/2012 Copenhagen, Denmark, September 14th, 2012 The workshop will be held in conjunction with ICFP 2012 http://www.icfpconference.org/icfp2012/ Important dates Proposal Deadline: 10th July 2012 Notification: 27th July 2012 Workshop: 14th September 2012 The Haskell Implementors' Workshop is to be held alongside ICFP 2012 this year in Copenhagen, Denmark. 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, and impromptu short talks. Scope and target audience ------------------------- It is important to distinguish the Haskell Implementors' Workshop from the Haskell Symposium which is also co-located with ICFP 2012. The Haskell Symposium is for the publication of Haskell-related research. In contrast, the Haskell Implementors' Workshop will have no proceedings -- although we will aim to make talk videos, slides and presented data available with the consent of the speakers. In the Haskell Implementors' Workshop, we hope to study the underlying technology. We want to bring together anyone interested in the nitty-gritty details behind turning plain-text source code into a deployed product. Having said that, members of the wider Haskell community are more than welcome to attend the workshop -- we need your feedback to keep the Haskell ecosystem thriving. The scope covers any of the following topics. There may be some topics that people feel we've missed, so by all means submit a proposal even if it doesn't fit exactly into one of these buckets: * Compilation techniques * Language features and extensions * Type system implementation * Concurrency and parallelism: language design and implementation * Performance, optimisation and benchmarking * Virtual machines and run-time systems * Libraries and tools for development or deployment Talks ----- At this stage we would like to invite proposals from potential speakers for a relatively short talk. We are aiming for 20 minute talks with 10 minutes for questions and changeovers. We want to hear from people writing compilers, tools, or libraries, people with cool ideas for directions in which we should take the platform, proposals for new features to be implemented, and half-baked crazy ideas. Please submit a talk title and abstract of no more than 200 words to: johan.tibell(a)gmail.com We will also have a lightning talks session which will be organised on the day. These talks will be 2-10 minutes, depending on available time. Suggested topics for lightning talks are to present a single idea, a work-in-progress project, a problem to intrigue and perplex Haskell implementors, or simply to ask for feedback and collaborators. Organisers ---------- * Lennart Augustsson (Standard Chartered Bank) * Manuel M T Chakravarty (University of New South Wales) * Gregory Collins - co-chair (Google) * Simon Marlow (Microsoft Research) * David Terei (Stanford University) * Johan Tibell - co-chair (Google)

ANNOUNCE: control-monad-loop 0.1
by Joey Adams 09 Jul '12

09 Jul '12

This package provides imperative-style loops supporting "continue" and "break". For example: import Control.Monad import Control.Monad.IO.Class import Control.Monad.Trans.Loop import Control.Monad.Trans.Class main :: IO () main = foreach [0..] $ \i -> foreach [0..] $ \j -> do when (j == 0) $ continue -- skip to next iteration when (j >= 5) $ exit -- exit the loop when (i >= 5) $ lift exit -- exit the outer loop by calling 'exit' in the parent monad liftIO $ print (i, j) It works by having the loop body run under the LoopT monad transformer, which provides early exit functions 'continue' and 'exit'. Functions like 'foreach' and 'while' run a LoopT callback, passing it continuations defining 'continue' and 'exit'. http://hackage.haskell.org/package/control-monad-loop

Reminder: HacPhi 2012 registration closing in two weeks
by wagnerdm＠seas.upenn.edu 08 Jul '12

08 Jul '12

Hello all, HacPhi 2012 is drawing near! To help us finalize the arrangements, we plan on closing the registration period on Friday, July 20, 2012 at 1430 local time (local to you!) ...two weeks before the beginning of the festivities. If you plan on coming, please drop us a line so that we know how many people to provide food and wireless for (and we all know which of those two is the more important ;-). Full instructions for registering are available on the wiki page [1], as well as information about making hotel and travel arrangements. The HacPhi wiki [2] has full details, but the skinny is this: we kick off at 1430 on Friday, August 3, and will hack together for three days (until August 5), with breaks for food and sleep. We will have a time for short talks as well -- let us know if you're interested in telling us a bit about your latest exploits. Whether you're a raw recruit or a grizzled code veteran, come join your Haskell-y comrades-in-arms for a weekend of hacking and fun! - The HacPhi team Brent Yorgey (byorgey) Daniel Wagner (dmwit) Chris Casinghino (ccasin) [1] http://www.haskell.org/haskellwiki/Hac_%CF%86/Register [2] http://www.haskell.org/haskellwiki/Hac_%CF%86

ANNOUNCE: lens-family-th 0.1.0.0
by Dan Burton 07 Jul '12

07 Jul '12

Following the announcement of lens-family, I'm pleased to announce lens-family-th 0.1.0.0, a Template Haskell library supplying macros to generate lens-family lenses for fields of data types declared with record syntax. Be warned that currently, type signatures are *not* generated alongside the lens definitions. Type inference should correctly determine the type of the generated lenses, but I have structured the library code so that in the future, type signatures can also be generated. Patches welcome! http://hackage.haskell.org/package/lens-family-th -- Dan Burton

CFP: First Workshop on Programming the Semantic Web - PSW 2012
by Janis Voigtländer 06 Jul '12

06 Jul '12

[CALL FOR PAPERS] First Workshop on Programming the Semantic Web - PSW'12 co-located with ISWC'12, 11th International Semantic Web Conference (ISWC 2012), 11-15 November, Boston, USA Workshop website: http://www.inf.puc-rio.br/~psw12 Contact: psw12(a)inf.puc-rio.br IMPORTANT DATES =============== Abstract submission deadline: *July 24, 2012* Paper submission deadline: *July 31, 2012* Notification of acceptance: August 21, 2012 Camera ready papers: September 10, 2012 Workshop date: November 11 or 12, 2012 GOALS AND TOPICS ================ The Web of Data is growing at an enormous pace. However, the development of dedicated software applications, capable to deal efficiently in information-rich spaces, of which the Semantic Web is one dimension, is not yet mainstream. Reasons for that include one (or more) of the following research issues: lack of integrated development environments (IDEs, such as Visual Studio and Eclipse), poor programming language support, lack of standard testbeds and/or benchmarks, inadequate training, and perhaps the need for curricula revision. Properly addressing these issues requires interdisciplinary skills, and the collaboration between academia and industry. The First Workshop on Programming the Semantic Web invites submissions that explore the gap between today's data management challenges, particularly the ones related to dealing with large amounts of semantically rich data, and the lack of adequate tools. We are looking for contributions that discuss, promote and further advance the programming facet of the Semantic Web, including the development of new languages, extension of existing ones, and the inclusion of semantic enabled capabilities into existing IDEs. Papers submitted to PSW'12 should explore open research problems, and must not have been accepted for publication elsewhere or be under review for another workshop or conference. All papers will be peer-reviewed by at least three PC members. Topics of interest include, but are not limited to: * Languages, tools, and methodologies for representing and managing Information-rich data * Novel programming paradigms aimed at the Semantic Web/ linked data /Information-rich spaces in general * Impact of specific application areas (e.g. e-science, e-gov, sensors) on Information-rich application design * Data Visualization * Programming Patterns for data handling * Evaluation of data quality * Plugins and IDEís for information rich application development * Ontologies, Schemata, Taxonomies and Types interplay * query, integration, and analysis of Semantic Web data * Cleaning and provenance of Semantic Web data, services, and processes * Mashing up data and processes SUBMISSION GUIDELINES AND PROCEEDINGS ------------------------------------- Papers submitted to *PSW 2012* should explore open research problems, and must not have been accepted for publication elsewhere or be under review for another workshop or conference. All papers will be peer-reviewed by at least three PC members. The workshop will accept: * Full research and experience papers (maximum length: 12 pages) * Position and demonstration Papers (maximum length: 4 pages) Submissions must be formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS) (http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0) Papers should be submitted electronically, in PDF format, via EasyChair. All submissions will be peer-reviewed by members of the international program committee. Paper acceptance will be based on originality, significance, technical soundness, and clarity of presentation. Submission link coming soon! * Best papers will have the opportunity to be published in a book on Data Driven Programming, to be published by Springer fall 2013.* At least one author per accepted paper must register and participate in the workshop. Registration is subject to the terms, conditions and procedure of the main ISWC conference to be found on their website. ORGANIZING COMMITTEE -------------------- Karin Breitman, EMC Research Center Evelyne Viegas, Microsoft Research Steffen Staab, Universtity of Koblenz-Landau Jan Vitek, Purdue University Contact: psw12(a)inf.puc-rio.br PROGRAM COMMITTEE ----------------- Alexander Paar, TWT Science and Innovation Andy Gordon, Microsoft Research Axel Polleres, Siemens Daniel Oberle, SAP Don Syme, Microsoft Research Gerd Gröner, University of Koblenz-Landau Haym Hirsh, Rutgers University Janis Voigtländer, University of Bonn Jeff Pan, University of Aberdeen Judith Bishop, Microsoft Research Manfred Hauswirth, DERI Nigel Hoorspool, University of Victoria Peter Fox, Rensselaer Polytechnic Institute Ralf Lämmel, University of Koblenz-Landau Ralf Möller, TU Harburg Sören Auer, University of Leipzig Tim Finin, University of Maryland Tomas Petricek, Cambridge University

ANNOUNCE: lens-family 0.0.0
by roconnor＠theorem.ca 06 Jul '12

06 Jul '12

I'm pleased to announce the first release of lens-family-core and lens-family. This package provide first class(†) functional references. In addition to the usual operations of getting, setting and composition, plus integration with the state monad, lens families provide some unique features: * Polymorphic updating * Cast projection functions to read-only lenses * Cast semantic editor combinators to modify-only lenses (†) For optimal first-class support use the lens-family package with rank 2 / rank N polymorphism. Lens.Family.Clone allows for first-class support of lenses for those who require Haskell 98. -- Russell O'Connor <http://r6.ca/> ``All talk about `theft,''' the general counsel of the American Graphophone Company wrote, ``is the merest claptrap, for there exists no property in ideas musical, literary or artistic, except as defined by statute.''

ANNOUNCE: Sifflet visual programming language, release 2.0.0.0
by gdweber＠iue.edu 06 Jul '12

06 Jul '12

I don't usually get this excited about a release, but after nearly a year of not being able to do any work on Sifflet, I am now *Extremely Happy* to announce -- Sifflet and sifflet-lib 2.0.0.0, now available on Hackage! This version introduces a type checker and partial support for higher order functions in Sifflet, the visual, functional programming language and support system for students learning about recursion. Sifflet programmers define functions by drawing diagrams, and the Sifflet interpreter uses the diagrams to show how function calls are evaluated. Sifflet-lib is the library containing many modules of the Sifflet application. What's New ---------- July 5, 2012, Version 2.0.0.0: * Partial support for higher order functions, like map and filter. See Lesson 10 in the Sifflet Tutorial. * Sifflet now provides type checking and type inference. This should make it possible to provide exporters to languages, like Java, that require type declarations. (Unfortunately, the error messages for incorrectly typed functions are not yet friendly for novice programmers.) * Added a menu command (File / Save image ...) to save vector graphic images of functions in the Sifflet Workspace or Edit function windows. Images can be saved in SVG, Postscript, and PDF formats. * Reorganized hierarchical modules in the library to conform to the recommended practice. See the RELEASE-NOTES for details. * Several bugs are fixed, including one which crashed Sifflet when applying a function definition with an incomplete `if` tree. See ISSUES for details. * There is a new file format for saving function definitions to support higher-order function types. The new format, siffml 2.0, has a RELAX NG schema; siffml 1.0 files can still be opened in Sifflet 2.0. About Sifflet ------------- Sifflet is a visual, functional programming language intended as an aid for learning about recursion. * A picture explains Sifflet better than words: please see the screenshot showing how to evaluate 3!: http://mypage.iu.edu/~gdweber/software/sifflet/home.html * Features: - Visual editor. - Visual tracer/debugger which shows how recursive and other function calls are evaluated. To support active learning and avoid screen clutter, Sifflet displays only as much of the computation as the user requests. - Carefully crafted tutorial with 44 pictures, about 26 pages if printed. - Number, string, and list data types. - Small collection of primitive functions. - Runnable examples of compound functions. - Sifflet functions can be exported to Scheme, Python 3, and Haskell.
