Reminder [CFP] 6th European Lisp Workshop, July 6th 2009
by Didier Verna 31 Mar '09

31 Mar '09

+------------------------------------------------------------+ | CALL FOR PAPERS | | 6th European Lisp Workshop | | July 6, Genova, Italy - co-located with ECOOP 2009 | +------------------------------------------------------------+ Important Dates =============== Submission deadline: April 08, 2009 Notification of acceptance: May 08, 2009 ECOOP early registration deadline: May 20, 2009 6th European Lisp Workshop: July 06, 2009 Please note that registration must be done with ECOOP itself. For more information visit http://elw.bknr.net/2009 Contact: Didier Verna, didier(a)lrde.epita.fr 2009 Special News ================= This year, and for the first time, the workshop proceedings will be published in the ACM Digital Library. Also, the workshop will feature interactive tutorial/demo/coding sessions (see below). Overview ======== "...Please don't assume Lisp is only useful for Animation and Graphics, AI, Bio-informatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list." -- Kent Pitman Lisp, one of the eldest computer languages still in use today, is gaining momentum again. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch, making it the ideal candidate for writing Domain Specific Languages. Common Lisp, with the Common Lisp Object System (CLOS), was the first object-oriented programming language to receive an ANSI standard and retains the most complete and advanced object system of any programming language, while influencing many other object-oriented programming languages that followed. This workshop will address the near-future role of Lisp-based languages in research, industry and education. We solicit contributions that discuss the opportunities Lisp provides to capture and enhance the possibilities in software engineering. We want to promote lively discussion between researchers proposing new approaches and practitioners reporting on their experience with the strengths and limitations of current Lisp technologies. The workshop will have two components: there will be formal talks, and interactive turorial/demo/coding sessions. Papers ====== Formal presentations in the workshop should take between 20 minutes and half an hour; additional time will be given for questions and answers. Suggested topics include (but are not limited to): - Experience reports / Case studies - Educational approaches - Software Evolution - Development Aids - Persistent Systems - Dynamic Optimization - Implementation techniques - Hardware Support - Efficiency / Distribution / Parallel programming - Macro-, reflective-, meta- and/or rule-based development approaches - Protocol Meta-programming and Libraries - Context-Oriented, Domain-Oriented and Generative Programming Interactive Tutorial/Demo/Coding Sessions ========================================= Additionally, we invite less formal talks in the form of interactive tutorial/demo/coding sessions. The purpose of these sessions is to both demonstrate and receive feedback on any interesting Lisp system, either stable or under development. Being less formal than technical paper presentations, it is expected that these sessions be highly interactive. Submission Guidelines ===================== Potential contributors are encouraged to submit: - a long paper (around 10 pages) presenting scientific and/or empirical results about Lisp-based uses or new approaches for software engineering purposes, - a short essay (5 pages) defending a position about where research, practice or education based on Lisp should be heading in the near future, - a proposal for an interactive tutorial/demo/coding session (1-2 pages) describing the involved library or application, and the subject of the session. Papers (both long and short) should be formatted following the ACM SIGS guidelines (see http://www.acm.org/sigs/publications/proceedings-templates) and include ACM classification categories and terms (see http://www.acm.org/about/class/1998). Authors will later be required to sign an ACM copyright form. Submissions should be mailed as PDF to Didier Verna (didier(a)lrde.epita.fr) before the submission deadline.

Séminaire Performance et Généricité du LRDE le Mercredi 25 mars 2009
by Akim Demaille 17 Mar '09

17 Mar '09

Chers collègues, La prochaine session du séminaire Performance et Généricité du LRDE (Laboratoire de Recherche et Développement de l'EPITA) aura lieu le Mercredi 25 mars 2009 (14h-15h30). Au programme: * 14h: Que se cache-t-il derrière ce type ? -- Yann Régis-Gianas, laboratoire PPS (Univ. Paris Diderot), équipe πr² (INRIA) http://www.pps.jussieu.fr/~yrg Si une fonction φ promet de manipuler une valeur de type α sans l'observer, on peut utiliser son code sans risque pour toutes les affectations possibles de α : que la valeur soit entière (α = int) ou qu'elle soit un arbre (α = tree), la fonction se comportera toujours de façon identique. Cette propriété s'appelle le polymorphisme paramétrique, l'essence de la généricité. Promettre de ne pas observer de trop près son argument est un fardeau parfois insupportable pour une fonction, pour des raisons algorithmiques (comment prendre une décision sans savoir ce que vaut mon argument ?), ou encore pour des raisons de performances de bas-niveau (si je sais que α = int, je peux utiliser une primitive dédiée de mon processeur). Même si le type d'une valeur est caché derrière un type plus abstrait α, on peut fournir des mécanismes pour « le redécouvrir » grâce à des tests dynamiques ou à des raisonnements purement statiques. La propriété qui permet de diriger son calcul par la forme des types est appelée le polymorphisme intentionnel. Dans cet exposé, nous présenterons plusieurs versions du polymorphisme intentionnel offertes par différents systèmes de types et de preuves sûrs (c'est-à-dire garantissant que les programmes ne peuvent pas planter et sont corrects vis-à-vis de leur spécification). Yann Régis-Gianas est maître de conférence de l'Université Paris Diderot. Ancien élève de l'EPITA et du LRDE (promo CSI 2003), il a poursuivi son cursus par un DEA SPL (précurseur de l'actuel MPRI) et par un doctorat au sein de l'équipe Gallium de l'INRIA. Il étudie le design des langages de programmation à typage statique garantissant l'absence d'erreurs dans les programmes. Pour plus de renseignements, consultez http://seminaire.lrde.epita.fr/. L'entrée du séminaire est libre. Merci de bien vouloir diffuser cette information le plus largement possible.
