================================================================================ BOB Conference 2023 "What happens when we use what's best for a change?" https://bobkonf.de/2023/cfc.html Berlin, Mar 17 Call for Contributions Deadline: November 21, 2022 ================================================================================ You are actively engaged in advanced software engineering methods, solve ambitious problem with software and are open to cutting-edge innovation? Attend this conference, meet people that share your goals, and get to know the best software tools and technologies available today. We strive to offer a day full of new experiences and impressions that you can use to immediately improve your daily life as a software developer. If you share our vision and want to contribute, submit a proposal for a talk or tutorial! NOTE: The conference fee will be waived for presenters. Travel expenses will not be covered (for exceptions see "Speaker Grants"). Online or Onsite ---------------- We expect we'll be able to hold BOB 2023 in Berlin. Note that we intend to provide a safe environment for all participants. There will be space outside to eat and chat. We may ask you to wear a mask indoors when not presenting or eating, and may also ask you to take a COVID test on-site before the event. If an on-site BOB is not possible, we'll make BOB a successful online event, like BOB 2021 and BOB 2022. Should BOB happen online, we will likely ask for pre-recorded talks to make room for questions and social interactions during the actual conference day. (Of course, we'll provide assistance making those recordings.) Tutorials will likely happen as a live-session. Shepherding ----------- The program committee offers shepherding to all speakers. Shepherding provides speakers assistance with preparing their sessions. Specifically: - advice on structure and presentation - review of talk slides - assistance with recording - review of recording, if applicable Speaker Grants -------------- BOB has Speaker Grants available to support speakers from groups under-represented in technology. We specifically seek women speakers, speakers of color, and speakers who are not able to attend the conference for financial reasons. Topics ------ We are looking for talks about best-of-breed software technology, e.g.: - functional programming - persistent data structures and databases - event-based modelling and architecture - "fancy types" (dependent types, gradual typing, linear types, ...) - formal methods for correctness and robustness - abstractions for concurrency and parallelism - metaprogramming - probabilistic programming - math and programming - controlled side effects - program synthesis - next-generation IDEs - effective abstractions for data analytics - … everything really that isn’t mainstream, but you think should be - … includeing rough ideas worth discussing. Presenters should provide the audience with information that is practically useful for software developers. Challenges ---------- Furthermore, we seek contributions on successful approaches for solving hard problems, for example: - bias in machine-learning systems - digital transformation in difficult settings - accessibiltity - systems with critical reliability requirements - ecologically sustainable software development We're especially interested in experience reports. Other topics are also relevant, e.g.: - introductory talks on technical background - overviews of a given field - demos and how-tos Requirements ------------ We accept proposals for presentations of 45 minutes (40 minutes talk + 5 minutes questions), as well as 90 minute tutorials for beginners. The language of presentation should be either English or German. Your proposal should include (in your presentation language of choice): - An abstract of max. 1500 characters. - A short bio/cv - Contact information (including at least email address) - A list of 3-5 concrete ideas of how your work can be applied in a developer's daily life - additional material (websites, blogs, slides, videos of past presentations, …) - Don't be confused: The system calls a submission event. Organisation ------------ - Direct questions to konferenz at bobkonf dot de - Proposal deadline: November 21, 2022 - Notification: December 5, 2022 - Program: December 12, 2022 Submit here: https://pretalx.com/bob-2023/submit/ Program Committee ----------------- (more information here: https://bobkonf.de/2023/programmkomitee.html) - Matthias Fischmann, Wire - Matthias Neubauer, SICK AG - Nicole Rauch, Softwareentwicklung und Entwicklungscoaching - Michael Sperber, Active Group - Stefan Wehr, Hochschule Offenburg Scientific Advisory Board - Annette Bieniusa, TU Kaiserslautern - Torsten Grust, Uni Tübingen - Peter Thiemann, Uni Freiburg

Re: [Haskell-cafe] CFP for PEPM 2023 (Deadline extended)
by Edwin Brady 14 Oct '22

14 Oct '22

Apologies, it's Tuesday 18th AoE (next week), not Tuesday 13th. Thanks to those who pointed out the error and sorry for the extra noise. From: Edwin Brady <ecb10(a)st-andrews.ac.uk> Dear all, (With apologies for any duplicate copies). Please see the CFP for PEPM 203 below. We have received some requests for extensions, and extended the deadline to next Tuesday. Note that short papers, including tool demos, works in progress and extended abstracts, are welcome too! Edwin and Jens -- CALL FOR PAPERS -- ACM SIGPLAN Workshop on PARTIAL EVALUATION AND PROGRAM MANIPULATION (PEPM) 2023 =============================================================================== * Website : https://popl23.sigplan.org/home/pepm-2023 * Time : 16th--17th January 2023 * Place : Boston, Massachusetts, United States (co-located with POPL 2023) The ACM SIGPLAN Workshop on Partial Evaluation and Program Manipulation (PEPM) has a history going back to 1991 and has been co-located with POPL every year since 2006. It originated with the discoveries of useful automated techniques for evaluating programs with only partial input. Over the years, the scope of PEPM has expanded to include a variety of research areas centred around the theme of semantics-based program manipulation — the systematic exploitation of treating programs not only as subjects to black-box execution but also as data structures that can be generated, analysed, and transformed while establishing or maintaining important semantic properties. Scope ----- In addition to the traditional PEPM topics (see below), PEPM 2023 welcomes submissions in new domains, in particular: * Semantics based and machine-learning based program synthesis and program optimisation. * Modelling, analysis, and transformation techniques for distributed and concurrent protocols and programs, such as session types, linear types, and contract specifications. More generally, topics of interest for PEPM 2023 include, but are not limited to: * Program and model manipulation techniques such as: supercompilation, partial evaluation, fusion, on-the-fly program adaptation, active libraries, program inversion, slicing, symbolic execution, refactoring, decompilation, and obfuscation. * Techniques that treat programs/models as data objects including metaprogramming, generative programming, embedded domain-specific languages, program synthesis by sketching and inductive programming, staged computation, and model-driven program generation and transformation. * Program analysis techniques that are used to drive program/model manipulation such as: abstract interpretation, termination checking, binding-time analysis, constraint solving, type systems, automated testing and test case generation. * Application of the above techniques including case studies of program manipulation in real-world (industrial, open-source) projects and software development processes, descriptions of robust tools capable of effectively handling realistic applications, benchmarking. Examples of application domains include legacy program understanding and transformation, DSL implementations, visual languages and end-user programming, scientific computing, middleware frameworks and infrastructure needed for distributed and web-based applications, embedded and resource-limited computation, and security. This list of categories is not exhaustive, and we encourage submissions describing new theories and applications related to semantics-based program manipulation in general. If you have a question as to whether a potential submission is within the scope of the workshop, please contact the programme co-chairs, Edwin Brady (ecb10(a)st-andrews.ac.uk<mailto:ecb10@st-andrews.ac.uk>) and Jens Palsberg (palsberg(a)ucla.edu<mailto:palsberg@ucla.edu>). Submission categories and guidelines ------------------------------------ Two kinds of submissions will be accepted: * Regular Research Papers should describe new results, and will be judged on originality, correctness, significance, and clarity. Regular research papers must not exceed 12 pages. * Short Papers may include tool demonstrations and presentations of exciting if not fully polished research, and of interesting academic, industrial, and open-source applications that are new or unfamiliar. Short papers must not exceed 6 pages. References and appendices are not included in page limits. Appendices may not be read by reviewers. Both kinds of submissions should be typeset using the two-column ‘sigplan’ sub-format of the new ‘acmart’ format available at: http://sigplan.org/Resources/Author/ and submitted electronically via HotCRP: https://pepm23.hotcrp.com/ Reviewing will be single-blind. Submissions are welcome from PC members (except the two co-chairs). Accepted regular research papers will appear in formal proceedings published by ACM, and be included in the ACM Digital Library. Accepted short papers do not constitute formal publications and will not appear in the proceedings. At least one author of each accepted contribution must attend the workshop (physically or virtually) and present the work. In the case of tool demonstration papers, a live demonstration of the described tool is expected. Important dates --------------- * Paper submission deadline (EXTENDED): **Tuesday 13th October 2022 (AoE)** * Author notification (EXTENDED) : **Tuesday 15th November 2022 (AoE)** * Workshop : **Monday 16th January 2023 to Tuesday 17th January 2023** Best paper award ---------------- PEPM 2023 continues the tradition of a Best Paper award. The winner will be announced at the workshop. Programme committee ------------------- * Chairs: Edwin Brady (University of St Andrews, UK) Jens Palsberg (University of California Los Angeles, USA) * Nada Amin Harvard (USA) * Adam Barwell (Imperial College London, UK) * Nicolas Biri (Input Output Global) * David Castro-Perez (University of Kent at Canterbury, UK) * Cristina David (University of Bristol, UK) * Atsushi Igarashi (Kyoto University, Japan) * Yukiyoshi Kameyama (University of Tsukuba, Japan) * Geoffrey Mainland (Drexel University, USA) * Hila Peleg (Technion Israel Institute of Technology, Israel) * Casper Bach Poulsen (Delft University of Technology, Netherlands) * Sukyoung Ryu (KAIST, Korea) * Sven-Bodo Scholz (Radboud University Nijmegen, Netherlands) * Ilya Sergey (National University of Singapore, Singapore) * Satnam Singh (Groq Inc, USA) * Elena Zucca (University of Genova, Italy)

by Jeehoon Kang 13 Oct '22

13 Oct '22

(Apologies if you receive multiple copies of this message) -------------------------------------------------------------------------- SRC@POPL 2023 Call for Submissions ACM Student Research Competition https://popl23.sigplan.org/track/POPL-2023-student-research-competition Location: Boston, Massachusetts, USA SRC Posters: Jan 18, 2023 (tentative) SRC Presentation: Jan 20, 2023 (tentative) -------------------------------------------------------------------------- Important Dates Abstract Submission: Fri 11 Nov 2022 Notification of (Conditional) Acceptance: Fri 2 Dec 2022 Re-Submission for Conditionally Accepted Abstracts: Wed 7 Dec 2022 Notification of Final Acceptance: Fri 9 Dec 2022 -------------------------------------------------------------------------- Overview POPL 2023 will host an ACM Student Research Competition, where undergraduate and graduate students can present their original research before a panel of judges and conference attendees. This year’s competition will consist of three rounds: • Round 1, Extended abstract: All students are encouraged to submit an extended abstract outlining their research. The submission should be up to three pages using “\documentclass[acmsmall,nonacm]{acmart}”. • Round 2, Poster at POPL: Based on the abstracts, a panel of judges will select the most promising entrants to participate in a poster session at POPL. In the poster session, students will be able to interact with POPL attendees and judges. After the poster session, three finalists in each category (graduate/undergraduate) will be selected to advance to the next round. • Round 3, Oral presentation at POPL: The last round will consist of a short oral live presentation at POPL to compete for the final awards in each category. This round will also select an overall winner who will advance to the ACM SRC Grand Finals. -------------------------------------------------------------------------- Call for Submission POPL invites students to participate in the Student Research Competition in order to present their research and get feedback from prominent members of the programming language research community. Please submit your extended abstracts through HotCRP: https://popl23src.hotcrp.com Submissions must be original research that is not already published at POPL or another conference or journal. One of the goals of the SRC is to give students feedback on ongoing, unpublished work. Furthermore, the abstract must be authored solely by the student. If the work is collaborative with others and/or part of a larger group project, the abstract should make clear what the student’s role was and should focus on that portion of the work. The extended abstract should be up to three pages using ‘\documentclass[acmsmall,nonacm]{acmart}’. Reference lists do not count towards the three-page limit. You may write appendices after the three-page limit, but please be noted that the committee is not required to read them. This year, we will have two review cycles. For each submission, one of the following decisions will be made: • Accept: abstracts that proceed to the next round unconditionally. • Conditional Accept: abstracts that receive revision suggestions from the PC members. Authors will have 5 days to revise the abstract accordingly and then resubmit. The revised abstracts will then be re-evaluated, and either accepted or rejected. • Reject: abstracts that will not proceed to the next round. -------------------------------------------------------------------------- Program Committee Jeehoon Kang, KAIST Danfeng Zhang, Pennsylvania State University Youyou Cong, Tokyo Institute of Technology Zeyu Ding, Binghamton University, USA Andrew K.

Request for Nominations to the GHC Steering Committee
by Joachim Breitner 06 Oct '22

06 Oct '22

Dear Haskell community, the GHC Steering committee is seeking nominations for one or more new members. The committee scrutinizes, nitpicks, improves, weighs and eventually accepts or rejects proposals that extend or change the language supported by GHC and other (public-facing) aspects of GHC. Our processes are described at https://github.com/ghc-proposals/ghc-proposals which is also the GitHub repository where proposals are proposed. In particular, please have a look at the bylaws at https://github.com/ghc-proposals/ghc-proposals/blob/master/committee.rst We are looking for a member who has the ability * to understand such language extension proposals, * to find holes and missing corner cases in the specifications, * foresee the interaction with other language features and specifications, * comment constructively and improve the proposals, * judge the cost/benefit ratio and * finally come to a justifiable conclusion. We look for committee members who have some of these properties: * have substantial experience in writing Haskell applications or libraries, which they can use to inform judgements about the utility or otherwise of proposed features, * have made active contributions to the Haskell community, for some time, * have expertise in language design and implementation, in either Haskell or related languages, which they can share with us. There is no shortage of people who are eager to get fancy new features into the language, both in the committee and the wider community. But each new feature imposes a cost, to implement, to maintain in perpetuity in GHC's code base, to learn, and to deal with its unexpected interaction with other features. We need to strike a balance, one that encourages innovation (as GHC always has) while still making Haskell attractive for real-world production use and for teaching. We therefore seek a balance of background, expertise, and views on the committee. Membership of the committee gives you the chance to influence the future direction of Haskell, and to serve the Haskell community. The committee’s work requires a small, but non-trivial amount of time, especially when you are assigned a proposal for shepherding. We estimate the workload to be around 2 hours per week, and our process works best if members usually respond to technical emails within 1-2 weeks (within days is even better). Please keep that in mind if your email inbox is already overflowing. To nominate yourself, please send an email to me (as the committee secretary) at mail(a)joachim-breitner.de until February 11th. I will distribute the nominations among the committee, and we will keep the nominations and our deliberations private. On behalf of the committee, Joachim Breitner -- Joachim Breitner mail(a)joachim-breitner.de http://www.joachim-breitner.de/
