two issues: GC and wrong pointers
by Tudor Girba Nov. 13, 2019

Nov. 13, 2019

Hi, During our work we encountered two issues we think should be considered critical. The first is that the garbage collector is unreliable on larger images: https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/391 We stumble on this when we manipulate larger pieces of data quite consistently in plain Pharo (7 or 8). We lack the knowledge of how to approach it, but we would happily pair and try to reproduce it with someone. The second one is that the sources contain wrong pointers, and this makes it hard to work with TFFI: https://github.com/pharo-project/pharo/issues/4967 This is already marked as important. We spent quite some time investigating this, especially in the context of TFFI, and we would be happy to pair to work through it. Would anyone be available for a collaboration in the following days? Cheers, Doru -- feenk.com "Not knowing how to do something is not an argument for how it cannot be done."

MoreVMs 2020 : Workshop on Modern Language Runtimes, Ecosystems, and VMs
by Fabio Niephaus Nov. 13, 2019

Nov. 13, 2019

============================================================================ Call for Extended Abstracts and Talks: MoreVMsâ20 4th Workshop on Modern Language Runtimes, Ecosystems, and VMs Co-located with â¹Programmingâºâ20 March 23rd or 24th, 2020, Porto, Portugal https://2020.programming-conference.org/home/MoreVMs-2020 ============================================================================ Following three previous successful editions, the MoreVMsâ20 workshop aims to bring together industrial and academic programmers to discuss the design, implementation, and usage of modern languages and runtimes. This includes aspects such as reuse of language runtimes, modular implementation, language design, and compilation strategies. By bringing together both researchers and practitioners, the workshop aims to enable a diverse discussion on how languages and runtimes are currently being utilized, and where they need to improve further. In addition to conventional workshop-style submissions, MoreVMs also accepts (and encourages) submissions that present early-stage work and emerging ideas. Relevant topics include, but are definitely not limited to, the following: - Extensible VM design (compiler- or interpreter-based VMs) - Reusable components (e.g. interpreters, garbage collectors, ...) - Static and dynamic compilation techniques - Techniques for targeting high-level languages such as JavaScript - Interoperability between languages - Tooling support (e.g. debugging, profiling, etc.) - Programming language development environments - Case studies of existing language implementation approaches - Language implementation challenges and trade-offs - Surveys and usage reports to understand usage in the wild - Ideas for more predictable performance - Ideas for how VMs could take advantage of new hardware features - Ideas for how we should build languages in the future Workshop Format and Submissions ------------------------------- We welcome presentation proposals in the form of extended abstracts (2 to 4 pages long) and talk proposals (title and 400 words abstract) discussing new techniques, insights, experiences, works-in-progress, as well as future visions, from either an academic or industrial perspective. The extended abstracts and talk proposals, and if the speakers wish, their slides, will be published on the workshop's website. Alternatively, extended abstracts can be published as part of the companion of â¹Programmingâºâ20 in the ACM DL. Publication in the ACM DL is conditional on the acceptance by the program committee. Please note that MoreVMsâ20 is organized as an academic workshop, and as such, speakers will be required to register for the workshop. We regret that we are unable to cover registration, travel, or accommodation costs for authors. Author Instructions ------------------- Submissions should use the ACM `acmart` format: https://www.acm.org/publications/proceedings-template If you are using LaTeX, submissions should use the 'acmart' document class with the 'sigconf' option, and with a font size of 9 point. Please use the Libertine/Biolinum font family. Please include page numbers in your submission using the LaTeX command `\settopmatter{printfolios=true}`. All submissions should be in PDF format. Please also ensure that your submission is legible when printed on a black and white printer. In particular, please check that colors remain distinct and font sizes are legible. Submission Site: https://easychair.org/conferences/?conf=morevms20 Important Dates --------------- Extended abstract and talk submissions: 2020-01-10 Author notification: 2020-02-10 Camera Ready: 2020-02-21 Workshop: 2020-03-23 or 2020-03-24 All deadlines are Anywhere on Earth (AoE), i.e. GMT/UTC-12:00 hour. Invited Speakers ----------------- Roman Kennke, Shenandoah GC Project Lead, Red Hat Leszek Swirski, Software Engineer, V8 Team, Google Program Committee ----------------- Nicolas B. Pierron, Mozilla, France ClÃ©ment BÃ©ra, Google, Denmark Elisa Gonzalez Boix, Vrije Universiteit Brussel, Belgium Stephen Kell, University of Kent, United Kingdom Christoph Kirsch, University of Salzburg, Austria Hidehiko Masuhara, Tokyo Institute of Technology, Japan Gabriela Alexandra Moldovan, Cloudflare, United Kingdom David Pearce, Victoria University of Wellington, New Zealand Manuel Rigger, ETH Zurich, Switzerland Jennifer B.

deprecating use traditional formatter
by ducasse Nov. 13, 2019

Nov. 13, 2019

Hi In the new implementation of the code formattter I will remove useTraditionalPrecedence. This settings put additional parentheses around binary selector but I find it cumbersome While it may make sense for it turns foo ^ 1 + 2 * 3 into foo ^ (1 + 2) * 3 foo ^ 1 * 3 + 2 foo ^ (1 | 2) % 3 foo ^ 1 % 2 | 3 So let me know what you think but I will be hard to convince :) Stef
