11 Dec '14

Welcome to issue 313 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers from November 16 to December 6, 2014 Quotes of the Week * Dijkstra: How do we convince people that in programming simplicity and clarity (in short: what mathematicians call "elegance") are not a dispensable luxury, but a crucial matter that decides between success and failure? * Dijkstra: Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better. * monochrom: those who have learned from history are bound to helplessly watch other people repeat it.

ANNOUNCE: Applied Functional Programming (AFP) Summerschool 6-17 July 2015, Utrecht, Netherlands
by Atze Dijkstra 08 Dec '14

08 Dec '14

=========== AFP Summerschool 2015 =========== Applied Functional Programming (AFP) Summerschool July 6-17, 2015 Utrecht University, Department of Information and Computing Sciences Utrecht, The Netherlands Summerschool & registration website: http://www.utrechtsummerschool.nl/courses/science/applied-functional-progra… AFP website : http://www.cs.uu.nl/wiki/USCS contact : Uscs-afp(a)lists.science.uu.nl *** The 2015 edition of the Applied Functional Programming (AFP) Summerschool in Utrecht, Netherlands will be held from 6-17 July 2015. The summerschool teaches Haskell on both beginners and advanced levels via lectures and lab exercises. More info can be found via the references above, included here is a summary from the summerschool info: ``Typed functional programming in Haskell allows for the development of compact programs in minimal time and with maximal guarantees about robustness and correctness. The course introduces Haskell as well as its theoretical underpinnings such as typed lambda calculus, and Damas-Milner type inference. There is ample opportunity to put this all in practice during lab sessions. Typed functional programming languages allow for the development of robust, concise programs in a short amount of time. The key advantages are higher-order functions as an abstraction mechanism, and an advanced type system for safety and reusability. This course introduces Haskell, a state-of-the-art functional programming language, together with some of its theoretical background, such as typed lambda calculi, referential transparency, Damas-Milner type inference, type level programming, and functional design patterns. We will combine this with applications of functional programming, concentrating on topics such as language processing, building graphical user interfaces, networking, databases, and programming for the web. The goal of the course is not just to teach the programming language and underlying theory, but also to learn about the Haskell community and to get hands-on experience by doing lab exercises or a Haskell project of your own.'' *** This year is somewhat special in that the Tour de France starts in Utrecht the weekend before the start of the summerschool. It is an opportunity for enjoying the related festivities. It also implies that housing may be more difficult the weekend before the summerschool, something to keep in mind when you wait with registration until the latest. regards, - Atze - Atze Dijkstra, Department of Information and Computing Sciences. /|\ Utrecht University, PO Box 80089, 3508 TB Utrecht, Netherlands. / | \ Tel.: +31-30-2534118/1454 | WWW : http://www.cs.uu.nl/~atze . /--| \ Fax : +31-30-2513971 .... | Email: atze(a)uu.nl ............... / |___\ _______________________________________________ Haskell mailing list Haskell(a)haskell.org http://www.haskell.org/mailman/listinfo/haskell

Modern society is increasingly dependent on software systems that are becoming larger and more complex. This poses new challenges to the various aspects of software engineering, for instance, software dependability in trusted computing, interaction with physical components in cyber physical systems, distribution in cloud computing applications, etc. Hence, new concepts and methodologies are required to enhance the development of software engineering from theoretical aspects. TASE 2015 aims to provide a forum for people from academia and industry to communicate their latest results on theoretical advances in software engineering. TASE 2015 is the 9th in the TASE series. The past TASE symposiums were successfully held in Shanghai ('07), Nanjing ('08), Tianjin ('09), Taipei ('10), Xi'an ('11), Beijing ('12), Birmingham ('13), Changsha('14).The proceedings of the TASE 2015 symposium are planned to be published by the IEEE Computer Society Press. ------ TOPICS ------ The symposium is devoted to theoretical aspects of software engineering. Topics of interest include, but are not limited to: * Requirements Engineering * Specification and Verification * Program Analysis * Software Testing * Model-Driven Engineering * Software Architectures and Design * Aspect and Object Orientation * Embedded and Real-Time Systems * Software Processes and Workflows * Component-Based Software Engineering * Software Safety, Security and Reliability * Reverse Engineering and Software Maintenance * Service-Oriented and Cloud Computing * Semantic Web and Web Services * Type System and Theory * Program Logics and Calculus * Probability in Software Engineering ---------- SUBMISSION ---------- Submission should be done through the TASE 2015 submission page, handled by the EasyChair conference system: https://www.easychair.org/conferences/?conf=tase2015 As in previous years, the proceedings of the conference are planned to be published by the IEEE Computer Society Press. Papers must be written in English and not exceed 8 pages in Two-Column IEEE format --------------- IMPORTANT DATES --------------- Abstract submission: 7 March 2015 (23h59 GMT) Paper submission: 14 March 2015 (23h59 GMT) Notification: 23 May 2015 Camera-ready: 13 June 2015 Conference: 12-14 September 2015 ------------- GENERAL CHAIR ------------- Jifeng He (East China Normal University, China) ----------------- PROGRAM CO-CHAIRS ----------------- Zhiqiu Huang (Nanjing University of Aeronautics and Astronautics, China) Jun Sun (Singapore University of Technology and Design) ----------------- STEERING COMMITTE ----------------- Keijiro Araki (Kyushu University, Japan) Shengchao Qin (Teesside University, UK) Jifeng He (East China Normal University, China) Huibiao Zhu (East China Normal University, China) Michael Hinchey (Lero, Ireland) ----------------- PROGRAM COMITTIEE ----------------- TBA ---------------- ORGANIZING CHAIR ---------------- Ou Wei (Nanjing University of Aeronautics and Astronautics, China) ---------------- PUBLICITY CHAIRS ---------------- Jun Hun (Nanjing University of Aeronautics and Astronautics, China) Jun Pang (University of Luxembourg) Yu Zhou (Nanjing University of Aeronautics and Astronautics, China)

2 PostDocs in HoTT
by Neil Ghani 04 Dec '14

04 Dec '14

=============================================== Homotopy Type Theory: Programming and Verification 2 PostDocs, each 4 Years Universities of Strathclyde and Nottingham Applications are invited for two postdocs and one PhD student to work on the recently funded EPSRC grant "Homotopy Type Theory: Programming and Verification" obtained by Professor Neil Ghani and Dr Conor McBride (University of Strathclyde), Dr Thorsten Altenkirch (University of Nottingham) and Dr Nicola Gambino (University of Leeds). One postdoc and will work on more theoretical aspects of the project in Nottingham, while the other postdoc will work on implementation issues in Strathclyde. Nevertheless, the reality is that we will be working as a team with frequent visits expected between ourselves and our collaborators. Homotopy Type Theory (HoTT) is a revolutionary new approach to type theory where types are interpreted as spaces, terms as points and equalities as paths. Decades of research in homotopy theory has uncovered the structure of such paths and HoTT uses this structure as the basis of a new theory of equality. Excitingly, within homotopy theory, one naturally studies higher homotopies of paths between paths and this gives the higher dimensional structure of equality we previously lacked. The objective of this grant is to translate the advances of HoTT into more concrete programming language and verification tools. For more details, please email Neil Ghani (ng(a)cis.strath.ac.uk<mailto:ng@cis.strath.ac.uk>) Conor McBride (conor.mcbride(a)strath.ac.uk<mailto:conor.mcbride@strath.ac.uk>) Thorsten Altenkirch (Thorsten.Altenkirch(a)nottingham.ac.uk<mailto:Thorsten.Altenkirch@nottingham.ac.uk>) Nicola Gambino (n.gambino(a)leeds.ac.uk<mailto:n.gambino@leeds.ac.uk>)

[apologies for any cross-posting] Call for Papers --------------------------------------------------------------------------- 13th International Conference on Logic Programming and Non-monotonic Reasoning LPNMR 2015 http://lpnmr2015.mat.unical.it/ Lexington, KY, USA September 27-30, 2015 (Collocated with the 4th Conference on Algorithmic Decision Theory 2015) --------------------------------------------------------------------------- AIMS AND SCOPE LPNMR 2015 is the thirteenth in the series of international meetings on logic programming and non-monotonic reasoning. LPNMR is a forum for exchanging ideas on declarative logic programming, non-monotonic reasoning, and knowledge representation. The aim of the conference is to facilitate interactions between researchers and practitioners interested in the design and implementation of logic-based programming languages and database systems, and those working in knowledge representation and nonmonotonic reasoning. LPNMR strives to encompass theoretical and experimental studies that have led or will lead to the construction of systems for declarative programming and knowledge representation, as well as their use in practical applications. This edition of LPNMR will feature several workshops, a special session dedicated to the 6th ASP Systems Competition, and will be collocated with the 4th Algorithmic Decision Theory Conference, ADT 2015. Joint LPNMR-ADT Doctoral Consortium will be a part of the program. Authors are invited to submit papers presenting original and unpublished research on all aspects of non-monotonic approaches in logic programming and knowledge representation. We invite submissions of both long and short papers. TOPICS Conference topics include, but are not limited to: 1. Foundations of LPNMR Systems: * Semantics of new and existing languages; * Action languages, causality; * Relationships among formalisms; * Complexity and expressive power; * Inference algorithms and heuristics for LPNMR systems; * Extensions of traditional LPNMR languages such as new logical connectives or new inference capabilities; * Updates, revision, and other operations on LPNMR systems; * Uncertainty in LPNMR systems. 2. Implementation of LPNMR systems: * System descriptions, comparisons, evaluations; * Algorithms and novel techniques for efficient evaluation; * LPNMR benchmarks. 3. Applications of LPNMR: * Use of LPNMR in formalization of Commonsense Reasoning and other areas of KR; * LPNMR languages and algorithms in planning, diagnosis, argumentation, reasoning with preferences, decision making and policies; * Applications of LPNMR languages in data integration and exchange systems, software engineering and model checking; * Applications of LPNMR to linguistics, psychology, and other sciences * Integration of LPNMR systems with other computational paradigms; * Embedded LPNMR: Systems using LPNMR subsystems. SUBMISSION LPNMR 2015 welcomes submissions of long papers (13 pages) or short papers (6 pages) in the following categories: * Technical papers * System descriptions * Application descriptions The indicated number of pages includes title page, references and figures. All submissions will be peer-reviewed and accepted papers will appear in the conference proceedings published in the Springer-Verlag Lecture Notes in Artificial Intelligence (LNAI/LNCS) series. At least one author of each accepted paper is expected to register for the conference to present the work. Submissions must be formatted according to the Springer LNCS author instructions, http://www.springer.com/comp/lncs/Authors.html must be written in English, and present original research. Paper submission will be electronic through the LPNMR-15 Easychair site: https://www.easychair.org/conferences/?conf=lpnmr2015 Two best papers of general AI interest will be invited for rapid publication in the journal Artificial Intelligence - Journal - Elsevier. Two best papers with narrower logic programming focus will be invited for a rapid publication in the journal Theory and Practice of Logic Programming. MULTIPLE SUBMISSION POLICY LPNMR 2015 will not accept any paper which, at the time of submission, is under review or has already been published or accepted for publication in a journal or another conference. Authors are also required not to submit their papers elsewhere during LPNMR's review period. However, these restrictions do not apply to previous workshops with a limited audience and without archival proceedings. ASSOCIATED EVENTS WORKSHOPS - LPNMR 2015 will include specialized workshops to be held on September 27 prior to the main conference. Currently planned workshops include: - Grounding, Transforming, and Modularizing Theories with Variables Organizers: Marc Denecker, Tomi Janhunen - Action Languages, Process Modeling, and Policy Reasoning Organizer: Joohyung Lee - Natural Language Processing and Automated Reasoning Organizers: Marcello Balduccini, Ekaterina Ovchinnikova, Peter Schueller - Learning and Nonmonotonic Reasoning Organizers: Alessandra Russo and Alessandra Mileo ASP COMPETITION - A special session dedicated to a discussion of the 6th ASP System Competition, including the methodology of the competition, benchmarks used, lessons learned and, most importantly, the results and the announcement of the winners. ALGORITHMIC DECISION THEORY (ADT) 2015 (collocated - same time and place) Algorithmic Decision Theory is a vibrant and growing area of research concerned with algorithmic aspects of problems arising in social choice and economics that involve optimal ways to aggregate preferences. The area abounds in hard computational problems and may be an axciting area of applications for ASP. The two conferences will seek ways to identify and promote synergies between their respective areas of focus. JOINT LPNMR-ADT DOCTORAL CONSORTIUM: Details to be announced co-Chairs: - Esra Erdem (LPNMR), Sabanci University, Turkey - Nick Mattei (ADT), NICTA, Australia IMPORTANT DATES (TENTATIVE) * Paper registration: April 13, 2015 * Paper submission: April 20, 2015 * Notification: June 1, 2015 * Final versions due: June 15, 2015 VENUE Lexington is a medium size, pleasant and quiet university town. It is located in the heart of the so-called Bluegrass Region in Central Kentucky. The city is surrounded by beautiful horse farms on green pastures dotted with ponds and traditional architecture stables, and small race tracks, and bordered by white or black fences. The Horse Museum is as beautifully located as it is interesting. Overall, the city has a nice feel that mixes well old and new. The conference will be held in the Hilton Lexington Downtown hotel.

The goal is to stimulate research in the use of logical formalisms and methods for specifying, performing, and analyzing computations, including mechanisms for mobility, modularity, concurrency, object-orientation, security, verification and static analysis. Papers related to the use of declarative paradigms and tools in industry and education are especially solicited. Topics of interest include, but are not limited to * Functional programming * Logic programming * Answer-set programming * Functional-logic programming * Declarative visual languages * Constraint Handling Rules * Parallel implementation and concurrency * Monads, type classes and dependent type systems * Declarative domain-specific languages * Termination, resource analysis and the verification of declarative programs * Transformation and partial evaluation of declarative languages * Language extensions for security and tabulation * Probabilistic modeling in a declarative language and modeling reactivity * Memory management and the implementation of declarative systems * Practical experiences and industrial application This year the conference will be co-located with the 25th International Symposium on Logic-Based Program Synthesis and Transformation (LOPSTR 2015). The conference will be held in Siena, Italy. Previous symposia were held at Canterbury (UK), Madrid (Spain), Leuven (Belgium), Odense (Denmark), Hagenberg (Austria), Coimbra (Portugal), Valencia (Spain), Wroclaw (Poland), Venice (Italy), Lisboa (Portugal), Verona (Italy), Uppsala (Sweden), Pittsburgh (USA), Florence (Italy), Montreal (Canada), and Paris (France). You might have a look at the contents of past PPDP symposia. 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 chair in case of questions). Important Dates Abstract Submission: 14 March, 2015 Paper submission: 20 March, 2015 Notification: 14 May, 2015 Camera-ready: To be announced Symposium: 14-16 July, 2015 Authors should submit an electronic copy of the full paper in PDF. Papers should be submitted to the submission website for PPDP 2015. Each submission must include on its first page the paper title; authors and their affiliations; abstract; and three to four keywords. The keywords will be used to assist the program committee in selecting appropriate reviewers for the paper. Papers should consist of the equivalent of 12 pages under the ACM formatting guidelines. These guidelines are available online, along with formatting templates or style files. Submitted papers will be judged on the basis of significance, relevance, correctness, originality, and clarity.
