---------------------------------------------------------------------- CALL FOR TALK PROPOSALS HOPE 2014 The 3rd ACM SIGPLAN Workshop on Higher-Order Programming with Effects August 31, 2014 Gothenburg, Sweden (the day before ICFP 2014) http://hope2014.mpi-sws.org ---------------------------------------------------------------------- HOPE 2014 aims at bringing together researchers interested in the design, semantics, implementation, and verification of higher-order effectful programs. It will be *informal*, consisting of invited talks, contributed talks on work in progress, and open-ended discussion sessions. --------------------- Goals of the Workshop --------------------- A recurring theme in many papers at ICFP, and in the research of many ICFP attendees, is the interaction of higher-order programming with various kinds of effects: storage effects, I/O, control effects, concurrency, etc. While effects are of critical importance in many applications, they also make it hard to build, maintain, and reason about one's code. Higher-order languages (both functional and object-oriented) provide a variety of abstraction mechanisms to help "tame" or "encapsulate" effects (e.g. monads, ADTs, ownership types, typestate, first-class events, transactions, Hoare Type Theory, session types, substructural and region-based type systems), and a number of different semantic models and verification technologies have been developed in order to codify and exploit the benefits of this encapsulation (e.g. bisimulations, step-indexed Kripke logical relations, higher-order separation logic, game semantics, various modal logics). But there remain many open problems, and the field is highly active. The goal of the HOPE workshop is to bring researchers from a variety of different backgrounds and perspectives together to exchange new and exciting ideas concerning the design, semantics, implementation, and verification of higher-order effectful programs. We want HOPE to be as informal and interactive as possible. The program will thus involve a combination of invited talks, contributed talks about work in progress, and open-ended discussion sessions. There will be no published proceedings, but participants will be invited to submit working documents, talk slides, etc. to be posted on this website. ----------------------- Call for Talk Proposals ----------------------- We solicit proposals for contributed talks. Proposals should be at most 2 pages, in either plain text or PDF format, and should specify how long a talk the speaker wishes to give. By default, contributed talks will be 30 minutes long, but proposals for shorter or longer talks will also be considered. Speakers may also submit supplementary material (e.g. a full paper, talk slides) if they desire, which PC members are free (but not expected) to read. We are interested in talks on all topics related to the interaction of higher-order programming and computational effects. Talks about work in progress are particularly encouraged. If you have any questions about the relevance of a particular topic, please contact the PC chairs at the address hope2014 AT mpi-sws.org. Deadline for talk proposals: June 13, 2014 (Friday) Notification of acceptance: July 4, 2014 (Friday) Workshop: August 31, 2014 (Sunday) The submission website is now open: https://www.easychair.org/conferences/?conf=hope2014 --------------- Invited Speaker --------------- Verifying Security Properties of SES Programs Philippa Gardner, Imperial College London Secure ECMAScript (SES) is a subset of JavaScript, designed in such a way that untrusted code can safety co-exist with trusted code. We introduce a program logic for verifying security properties of SES programs. It follows separation logic in that we can make local assertions about local state. It is different from separation logic in that we can also make global assertions about the global state and its interface with the local state. For example, we can globally assert that untrusted objects do not contain pointers to local trusted objects. Such assertions are key for describing security properties of common SES programs. This logic builds on the work of Gardner, Maffeis and Smith on reasoning about a core fragment of JavaScript (POPL2012), and the recent work of Smith on extending the logic to handle higher-order functions. This is joint work with Gareth Smith and Thomas Wood, Imperial. --------------------- Workshop Organization --------------------- Program Co-Chairs: Neel Krishnaswami (University of Birmingham) Hongseok Yang (University of Oxford) Program Committee: Zena Ariola (University of Oregon) Ohad Kammar (University of Cambridge) Ioannis Kassios (ETH Zurich) Naoki Kobayashi (University of Tokyo) Paul Blain Levy (University of Birmingham) Aleks Nanevski (IMDEA) Scott Owens (University of Kent) Sam Staton (Radboud University Nijmegen) Steve Zdancewic (University of Pennsylvania)
