Extended Deadline and Final CFP: WPTE'14, First International Workshop on Rewriting Techniques for Program Transformations and Evaluation
by David Sabel 26 Apr '14

26 Apr '14

!!! EXTENDED DEADLINE !!! FINAL CALL FOR PAPERS First International Workshop on Rewriting Techniques for Program Transformations and Evaluation (WPTE'14) affiliated with RTA/TLCA 2014 (a FLoC 2014 workshop, FLoC is part of the Vienna Summer of Logic 2014) 13th July 2014, Vienna, Austria http://www.ki.informatik.uni-frankfurt.de/WPTE14 Aims and Scope ============== The aim of WPTE is to bring together the researchers working on program transformations, evaluation, and operationally based programming language semantics, using rewriting methods, in order to share the techniques and recent developments and to exchange ideas to encourage further activation of research in this area. Topics of interest and in the scope of WPTE are: * Correctness of program transformations, optimizations and translations. * Program transformations for proving termination, confluence and other properties. * Correctness of evaluation strategies. * Operational semantics of programs, operationally-based program equivalences such as contextual equivalences and bisimulations. * Cost-models for arguing about the optimizing power of transformations and the costs of evaluation. * Program transformations for verification and theorem proving purposes. * Translation, simulation, equivalence of programs with different formalisms, and evaluation strategies. * Program transformations for applying rewriting techniques to programs in specific programming languages. * Program inversions and program synthesis. The programming languages of interest include pure, deterministic, impure, non-deterministic, concurrent, parallel languages, and may employ programming paradigms such as functional, logical, typed, imperative, object-oriented, and higher-order. Invited Speaker =============== Andy Gill (University of Kansas) Paper Submissions and Proceedings ================================= WPTE accepts two different kinds of contributions: * Full-papers: ------------ Full-papers must represent original work and should be submitted using the EasyChair interface. We plan to publish full-papers as formal proceedings in the 'OpenAccess Series in Informatics (OASIcs)' of 'Schloss Dagstuhl Leibniz-Zentrum fuer Informatik'. Full-papers should not exceed 12 pages using the OASIcs LaTeX-templates. * Work in progress: ----------------- There will also be a slot for presenting work in progress. An extended abstract of at most 4 pages is required to be submitted using the EasyChair interface. These contributions will not be included in the OASIcs proceedings but they will be distributed to the workshop partipicants. One author of each accepted paper or abstract is expected to present it at the workshop. Important Dates =============== * Submission deadline: 30 April 2014 (new!) * Notification of acceptance: 23 May 2014 * Deadline for camera-ready proceedings: 28 May 2014 * Workshop: 13 July 2014, Austria, Vienna Weblinks ======== * EasyChair Submission Website https://www.easychair.org/conferences/?conf=wpte14 * Homepage of WPTE'14 http://www.ki.informatik.uni-frankfurt.de/WPTE14 * OASIcs Website (including LaTeX templates): http://www.dagstuhl.de/en/publications/oasics * Vienna Summer of Logic 2014 http://vsl2014.at Program Committee ================= Takahito Aoto (RIEC, Tohoku University) Yuki Chiba (Japan Advanced Institute of Science and Technology) Fer-Jan de Vries (University of Leicester) Santiago Escobar (Universitat Politècnica de València) Maribel Fernández (King's College London) Johan Jeuring (Open Universiteit Nederland and Universiteit Utrecht) Delia Kesner (Université Paris-Diderot) Sergueï Lenglet (Université de Lorraine) Elena Machkasova (University of Minnesota, Morris) Joachim Niehren (INRIA Lille) David Sabel (Goethe-University Frankfurt am Main) Masahiko Sakai (Nagoya University) Manfred Schmidt-Schauß (Goethe-University Frankfurt am Main) - chair Eijiro Sumii (Tohoku University) Janis Voigtländer (University of Bonn) Harald Zankl (University of Innsbruck) Organizers ========== Manfred Schmidt-Schauß (Goethe-University Frankfurt am Main) - chair Masahiko Sakai (Nagoya University) David Sabel (Goethe-University Frankfurt am Main) Yuki Chiba (Japan Advanced Institute of Science and Technology) Sponsors ======== Vereinigung von Freunden und Förderern der Johann Wolfgang Goethe Universität Frankfurt am Main e.V. -- ____________________________________________________________ David Sabel Akademischer Rat Professur für Künstliche Intelligenz und Softwaretechnologie Goethe-Universität Frankfurt am Main http://www.ki.informatik.uni-frankfurt.de/persons/sabel ____________________________________________________________

24 Apr '14

Call for Copy: The Monad.Reader - Issue 24 -------------------------------------------- Whether you're an established academic or have only just started learning Haskell, if you have something to say, please consider writing an article for The Monad.Reader! The submission deadline for Issue 24 will be: **Saturday, July 5, 2014** The Monad.Reader ~~~~~~~~~~~~~~~~ The Monad.Reader is a electronic magazine about all things Haskell. It is less formal than journal, but somehow more enduring than a wiki- page. There have been a wide variety of articles: exciting code fragments, intriguing puzzles, book reviews, tutorials, and even half-baked research ideas. Submission Details ~~~~~~~~~~~~~~~~~~ NEW this issue: for my reviewing sanity, I am setting a soft page limit of fifteen pages. If you would like to write something longer, get in touch, but remember: brevity is the soul of wit. In any case, contact me if you intend to submit something -- the sooner you let me know what you're up to, the better. Please submit articles for the next issue to me by e-mail. Articles should be written according to the guidelines available from http://themonadreader.wordpress.com/contributing/ Please submit your article in PDF, together with any source files you used. The sources will be released together with the magazine under a BSD license. If you would like to submit an article, but have trouble with LaTeX please let me know and we'll work something out.

CUFP 2014: Call for Presentations
by Edward Kmett 20 Apr '14

20 Apr '14

Commercial Users of Functional Programming 2014: Call for Presentations COMMERCIAL USERS OF FUNCTIONAL PROGRAMMING 2014 CUFP 2014 http://cufp.org/conference CALL FOR PRESENTATIONS Gothenburg, Sweden Sep 4-6 Co-located with ICFP 2014 Sponsored by SIGPLAN Talk Proposal Submission Deadline 27 June 2014 Submission Form: http://goo.gl/5BJLul The annual CUFP workshop is a place where people can see how others are using functional programming to solve real world problems; where practitioners meet and collaborate; where language designers and users can share ideas about the future of their favorite language; and where one can learn practical techniques and approaches for putting functional programming to work. Giving a CUFP Talk ================== If you have experience using functional languages in a practical setting, we invite you to submit a proposal to give a talk at the workshop. We're looking for two kinds of talks: Experience reports are typically 25 minutes long, and aim to inform participants about how functional programming plays out in real-world applications, focusing especially on lessons learned and insights gained. Experience reports don't need to be highly technical; reflections on the commercial, management, or software engineering aspects are, if anything, more important. Technical talks are also 25 minutes long, and should focus on teaching the audience something about a particular technique or methodology, from the point of view of someone who has seen it play out in practice. These talks could cover anything from techniques for building functional concurrent applications, to managing dynamic reconfigurations, to design recipes for using types effectively in large-scale applications. While these talks will often be based on a particular language, they should be accessible to a broad range of programmers. We strongly encourage submissions from people in communities that are underrepresented in functional programming, including but not limited to women; people of color; people in gender, sexual and romantic minorities; people with disabilities; people residing in Asia, Africa, or Latin America; and people who have never presented at a conference before. We recognize that inclusion is an important part of our mission to promote functional programming. So that CUFP can be a safe environment in which participants openly exchange ideas, we abide by the SIGPLAN Conference Anti-Harassment Policy ( http://www.sigplan.org/Resources/Policies/Anti-harassment ). If you are interested in offering a talk, or nominating someone to do so, please submit your presentation before 27 June 2014 via the form at http://goo.gl/5BJLul You do not need to submit a paper, just a short proposal for your talk! There will be a short scribe's report of the presentations and discussions but not of the details of individual talks, as the meeting is intended to be more a discussion forum than a technical interchange. Nevertheless, presentations will be video taped and presenters will be expected to sign an ACM copyright release form. Note that we will need all presenters to register for the CUFP workshop and travel to Gothenburg at their own expense. Program Committee ================= Edward Kmett (McGraw Hill Financial), co-chair Marius Eriksen (Twitter, Inc.), co-chair Ozgun Ataman (Soostone, Inc.) Tim Chevalier (AlephCloud) Derek Elkins (Now Business Intelligence) Matthew Might (University of Utah) Richard Minerich (Bayard Rock) Audrey Tang (Apple, Inc.) Jason Zaugg (Typesafe) More information ================ For more information on CUFP, including videos of presentations from previous years, take a look at the CUFP website at http://cufp.org. Note that presenters, like other attendees, will need to register for the event. Acceptance and rejection letters will be sent out by July 16th. Guidance on giving a great CUFP talk ==================================== Focus on the interesting bits: Think about what will distinguish your talk, and what will engage the audience, and focus there. There are a number of places to look for those interesting bits. Setting: FP is pretty well established in some areas, including formal verification, financial processing and server-side web-services. An unusual setting can be a source of interest. If you're deploying FP-based mobile UIs or building servers on oil rigs, then the challenges of that scenario are worth focusing on. Did FP help or hinder in adapting to the setting? Technology: The CUFP audience is hungry to learn about how FP techniques work in practice. What design patterns have you applied, and to what areas? Did you use functional reactive programming for user interfaces, or DSLs for playing chess, or fault-tolerant actors for large scale geological data processing? Teach us something about the techniques you used, and why we should consider using them ourselves. Getting things done: How did you deal with large software development in the absence of a myriad of pre-existing support that are often expected in larger commercial environments (IDEs, coverage tools, debuggers, profilers) and without larger, proven bodies of libraries? Did you hit any brick walls that required support from the community? Don't just be a cheerleader: It's easy to write a rah-rah talk about how well FP worked for you, but CUFP is more interesting when the talks also spend time on what doesn't work. Even when the results were all great, you should spend more time on the challenges along the way than on the parts that went smoothly.

ZuriHac 2014 - Updates
by Bas van Dijk 17 Apr '14

17 Apr '14

Dear (potential) ZuriHac 2014 attendees, I would like to make a few announcements regarding ZuriHac 2014, a Haskell hackathon taking place in Zurich from Friday 6 June 2014 to Sunday 8 June 2014. Besides hacking on Haskell projects with core members of the community you will hear talks by Simon Marlow and Edward Kmett. Note that this event is open to any experience level, from beginners to gurus. In fact, one of the goals is to bring beginners in contact with experts so that the former can get a quick start in the Haskell community and the latter more help with their projects. For more information see: http://www.haskell.org/haskellwiki/ZuriHac2014 Registration ------------ I'm happy and sad to inform you that we've almost reached capacity for ZuriHac 2014. Happy because it looks like this might be the biggest Haskell Hackathon ever. Sad because I soon have to start adding new registrations to a waiting list. So if you want to join us, and haven't registered already, then please do so soon at: http://bit.ly/ZuriHac2014. Also if you've already registered but know you won't be able to make it, please cancel by emailing me to make room for others. T-Shirt ------- Like last year, each attendee will get a free ZuriHac T-shirt. If you've already registered, please tell me which sizes and model you would like to have: Male: S, M, L, XL, XXL Female: S, M, L, XL, XXL Host ---- Erudify, the company which is hosting ZuriHac, recently changed its name to Better. Do note that we haven't changed location. See our new website on why we have rebranded: http://better.com/en/rebranding Regards, The ZuriHac 2014 organizers

LOPSTR 2014: Second Call for Papers
by German Vidal 17 Apr '14

17 Apr '14

[Apologies for multiple copies] ================== SECOND CALL FOR PAPERS ================== 24th International Symposium on Logic-Based Program Synthesis and Transformation LOPSTR 2014 http://www.iasi.cnr.it/events/lopstr14/ University of Kent, Canterbury, UK, September 10-11, 2014 DEADLINES Abstract submission: May 30, 2014 Paper/Extended abstract submission: June 6, 2014 ============================================================ The aim of the LOPSTR series is to stimulate and promote international research and collaboration on logic-based program development. LOPSTR is open to contributions in logic-based program development in any language paradigm. LOPSTR has a reputation for being a lively, friendly forum for presenting and discussing work in progress. Formal proceedings are produced only after the symposium so that authors can incorporate this feedback in the published papers. The 24th International Symposium on Logic-based Program Synthesis and Transformation (LOPSTR 2014) will be held at the University of Kent, Canterbury, United Kingdom; previous symposia were held in Madrid, Leuven, Odense, Hagenberg, Coimbra, Valencia, Lyngby, Venice, London, Verona, Uppsala, Madrid, Paphos, London, Venice, Manchester, Leuven, Stockholm, Arnhem, Pisa, Louvain-la-Neuve, and Manchester. LOPSTR 2014 will be co-located with PPDP 2014 (International ACM SIGPLAN Symposium on Principles and Practice of Declarative Programming). Topics of interest cover all aspects of logic-based program development, all stages of the software life cycle, and issues of both programming-in-the-small and programming-in-the-large. Both full papers and extended abstracts describing applications in these areas are especially welcome. Contributions are welcome on all aspects of logic-based program development, including, but not limited to: * synthesis * transformation * specialization * composition * optimization * inversion * specification * analysis and verification * testing and certification * program and model manipulation * transformational techniques in SE * applications and tools Survey papers that present some aspects of the above topics from a new perspective, and application papers that describe experience with industrial applications are also welcome. Papers must describe original work, be written and presented in English, and must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal, conference, or workshop with refereed proceedings. Work that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC co-chairs in case of questions). Important Dates Abstract submission: May 30, 2014 Paper/Extended abstract submission: June 6, 2014 Notification: July 18, 2014 Camera-ready (for electronic pre-proceedings): August 25, 2014 Symposium: September 10-11, 2014 Submission Guidelines Authors should submit an electronic copy of the paper (written in English) in PDF, formatted in the Lecture Notes in Computer Science style. Each submission must include on its first page the paper title; authors and their affiliations; contact author's email; abstract; and three to four keywords which will be used to assist the PC in selecting appropriate reviewers for the paper. Page numbers should appear on the manuscript to help the reviewers in writing their report. Submissions cannot exceed 15 pages including references but excluding well-marked appendices not intended for publication. Reviewers are not required to read the appendices, and thus papers should be intelligible without them. Paper should be submitted via the Easychair submission website for LOPSTR 2014. If electronic submission is impossible, please contact the program co-chairs for information on how to submit hard copies. Proceedings The formal post-conference proceedings will be published by Springer in the Lecture Notes in Computer Science series. Full papers can be directly accepted for publication in the formal proceedings, or accepted only for presentation at the symposium and inclusion in informal proceedings. After the symposium, all authors of extended abstracts and full papers accepted only for presentation will be invited to revise and/or extend their submissions in the light of the feedback solicited at the symposium. Then, after another round of reviewing, these revised papers may also be published in the formal proceedings.

*** Apologies for cross-posting *** *** Please not the URL of the conference Web site: http://prdc.dependability.org/PRDC2014/ *** *Call for Papers: The 20th IEEE Pacific Rim International Symposium on Dependable Computing (PRDC 2014)* *Singapore Nov 18-21, 2014 * PRDC 2014 (http://prdc.dependability.org/PRDC2014/) is the twentieth in this series of symposia started in 1989 that are devoted to dependable and fault-tolerant computing. PRDC is recognized as the main event in the Pacific area that covers the many dimensions of dependability and fault tolerance, encompassing fundamental theoretical approaches, practical experimental projects, and commercial components and systems. As applications of computing systems have permeated into all aspects of daily life, the dependability of computing systems has become increasingly critical. This symposium provides a forum for countries around the Pacific Rim and other areas of the world to exchange ideas for improving the dependability of computing systems. Topics of interest include (but not limited to): - Software and hardware reliability, testing, verification, and validation - Dependability measurement, modeling, evaluation, and tools - Self-healing, self-protecting, and fault-tolerant systems - Software aging and rejuvenation - Safety-critical systems and software - Architecture and system design for dependability - Fault-tolerant algorithms and protocols - Reliability in cloud computing, Internet, and web systems and applications - Cloud and Internet Information security - Dependability issues in computer networks and communications - Dependability issues in distributed and parallel systems - Dependability issues in real-time systems, database, and transaction processing systems - Dependability issues in autonomic computing - Dependability issues in aerospace and embedded systems Paper Submissions Manuscripts should be submitted in the following categories: Regular Papers and Practical Experience Reports. Regular Papers should describe original research (not submitted or published elsewhere) and be not more than 10 pages using IEEE format guidelines <http://www.ieee.org/conferences_events/conferences/publishing/templates.html>or 20 pages double-spaced. Practical Experience Reports (max 6 pages using IEEE format guidelines or 12 pages double-spaced) should describe an experience or a case study, such as the design and deployment of a system or actual failure and recovery field data. The title page should include a 150-word abstract, five keywords, authors' names and affiliations, and a line specifying whether the submission is a Regular Paper or a Practical Experience Report. The full mailing address, phone, fax, and email address of the corresponding author should be specified. All submissions must be made electronically (in PDF format) on the submission web site <https://www.easychair.org/conferences/?conf=prdc2014>. Papers will be reviewed internationally and selected based on their originality, significance, relevance, and clarity of presentation. All accepted papers will be published by IEEE Computer Society Press. One outstanding paper will be selected to receive the Best Paper Award. Important Dates Submission deadline: May 2, 2014 Notification: June 25, 2014 Best regards Yuan-Fang
