UK Smalltalk User Group meeting: Smalltalk and Self hardware - 29 June 2022
by Giovanni Corriga July 11, 2022

July 11, 2022

For our June meeting, Merik Voswinkel will give us a presentation on Smalltalk and Self hardware with a focus on manycore parallelism and distributed computing. This follows from Jecel Assumpcao Jr's SiliconSqueak presentation at the California Smalltalkers meetup ( https://youtu.be/CfYnzVxdwZE ). Merik will bring us on a tour past 50 years of late bound message passing Smalltalk VMs, Smalltalk RISC processors, David Ungarâs RoarVM, adaptive compilers, concurrent aggregates, clone-reduce, a processor per object, FPGAâs, Morphle Logic, Croquet and Teatime , Wafer Scale Integration, hundred (M1 Ultra), thousands and million cores ASICs, Cuniform, Matroshca Brains and much more in our tourney towards the Wayne Gretzky invention game of inventing the future. If there is time weâll go burning the Smalltalk disk packs, the intergalactic network GUI and the destiny of computers as intellectual amplifiers for humans pervasively networked worldwide and how we are going to communicate with Aliens. Merik Voswinkel is an independent scientist who build his first transputer supercomputer for Smalltalk after the Byte 1981 Smalltalk issue, build one of the first internet providers, works on SiliconSqueak, wafer scale integrations and Enernet energy computing. This will be an online meeting from home. If you'd like to join us, please sign up on the Meetup page ( https://www.meetup.com/ukstug/events/286314641/ ).

Request : enhance halo visuals
by Mayuresh Kathe July 6, 2022

July 6, 2022

Hello, Quite a lot looks different in Pharo from Squeak, but the "halo" seems to have retained its old toy-like, gimmicky look. Would you please consider updating it to match the look-and-feel of the rest of the Pharo UI? Thank you, ~Mayuresh

Second Call for Papers: 15th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2022)
by Andrei Chis July 5, 2022

July 5, 2022

------------------------------------------------------------------------ 15th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2022) December 5-10, 2022 Auckland, New Zealand https://conf.researchr.org/home/sle-2022 http://www.sleconf.org/2022 Follow us on twitter: https://twitter.com/sleconf ------------------------------------------------------------------------ We are pleased to invite you to submit papers to the 15th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2022), held in conjunction with SPLASH, GPCE and SAS 2022. Based on the future developments the conference will be hosted in Auckland, New Zealand on December 5-10, 2022. --------------------------- Topics of Interest --------------------------- SLE covers software language engineering rather than engineering a specific software language. Topics of interest include, but are not limited to: - Software Language Design and Implementation - Approaches to and methods for language design - Static semantics (e.g. design rules, well-formedness constraints) - Techniques for specifying behavioral / executable semantics - Generative approaches (incl. code synthesis, compilation) - Meta-languages, meta-tools, language workbenches - Software Language Validation - Verification and formal methods for languages - Testing techniques for languages - Simulation techniques for languages - Software Language Integration and Composition - Coordination of heterogeneous languages and tools - Mappings between languages (incl. transformation languages) - Traceability between languages - Deployment of languages to different platforms - Software Language Maintenance - Software language reuse - Language evolution - Language families and variability, language and software product lines - Domain-specific approaches for any aspects of SLE (design, implementation, validation, maintenance) - Empirical evaluation and experience reports of language engineering tools - User studies evaluating usability - Performance benchmarks - Industrial applications - "Synergies between Language Engineering and emerging/promising research areas" - AI and ML language engineering (e.g., ML compiler testing, code classification) Quantum language engineering (e.g., language design for quantum machines) - Language engineering for physical systems (e.g., CPS, IoT, digital twins) - Socio-technical systems and language engineering (e.g., language evolution to adapt to social requirements) - Etc. --------------------------- Types of Submissions --------------------------- SLE accepts the following types of papers: - **Research papers**: These are "traditional" papers detailing research contributions to SLE. Papers may range from 6 to 12 pages in length, and may optionally include 2 further pages of bibliography/appendices. Papers will be reviewed with an understanding that some results do not need 12 full pages and may be fully described in fewer pages. - **New ideas / vision papers**: These are papers that may describe new, unconventional software language engineering research positions or approaches that depart from standard practice. They can describe well-defined research ideas that are at an early stage of investigation. They could also provide new evidence to challenge common wisdom, present new unifying theories about existing SLE research that provides novel insight or that can lead to the development of new technologies or approaches, or apply SLE technology to radically new application areas. New ideas / vision papers must not exceed 5 pages, and may optionally include 1 further page of bibliography / appendices. - **SLE Body of Knowledge**: The SLE Body of Knowledge (SLEBoK) is a community-wide effort to provide a unique and comprehensive description of the concepts, best practices, tools and methods developed by the SLE community. To this respect, the SLE conference will accept surveys, essays, open challenges, empirical observations and case study papers on the SLE topics. These can focus on but they are not limited to methods, techniques, best practices and teaching approaches. Papers in this category can have up to 20 pages, including bibliography/appendices. - **Tool papers**: These are papers which focus on the tooling aspects which are often forgotten or neglected in research papers. A good tool paper focuses on practical insights that are likely to be useful to other implementers or users in the future. Any of the SLE topics of interest are appropriate areas for tool demonstrations. Submissions must not exceed 5 pages and may optionally include 1 further page of bibliography / appendices. They may optionally come with an appendix with a demo outline / screenshots and/or a short video/screencast illustrating the tool. **Workshops**: Workshops will be organized by SPLASH. Please inform us and contact the SPLASH organizers if you would like to organize a workshop of interest to the SLE audience. Information on how to submit workshops can be found at the SPLASH 2022 Website. --------------------------- Important Dates --------------------------- All dates are Anywhere on Earth. * Abstract submissions: August 8, 2022 * Paper submissions: August 12, 2022 * Review notification: September 18, 2022 (starting of the rebuttal) * Author response period: September 28, 2022 (end of the rebuttal) * Notification: September 30, 2022 * Artifact submissions: October 11, 2022 * Camera-ready (for both rounds): October 15, 2022 * Artifact kick-the-tires Author response: October 24, 2022 * Artifact notification: November 11, 2022 * Conference: December 5-10, 2022 --------------------------- Format --------------------------- Submissions have to use the ACM SIGPLAN Conference Format "acmart"(http://sigplan.org/Resources/Author/#acmart-format) please make sure that you always use the latest ACM SIGPLAN acmart LaTeX template(https://www.acm.org/binaries/content/assets/publications/consolida…, and that the document class definition is `\documentclass[sigplan,anonymous,review]{acmart}`. Do not make any changes to this format! 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 in figures and tables are legible. To increase fairness in reviewing, a double-blind review process has become standard across SIGPLAN conferences. In this line, SLE will follow the double-blind process. Author names and institutions should be omitted from submitted papers, and references to the authorsâ own related work should be in the third person. No other changes are necessary, and authors will not be penalized if reviewers are able to infer their identities in implicit ways. All submissions must be in PDF format. The submission website is: https://sle22.hotcrp.com --------------------------- Concurrent Submissions --------------------------- Papers must describe unpublished work that is not currently submitted for publication elsewhere as described by SIGPLANâs Republication Policy (http://www.sigplan.org/Resources/Policies/Republication) Submitters should also be aware of ACMâs Policy and Procedures on Plagiarism (http://www.acm.org/publications/policies/plagiarism_policy) Submissions that violate these policies will be desk-rejected. --------------------------- Policy on Human Participant and Subject Research --------------------------- Authors conducting research involving human participants and subjects must ensure that their research comply with their local governing laws and regulations and the ACMâs general principles as stated in the ACMâs Publications Policy on Research Involving Human Participants and Subjects (https://www.acm.org/publications/policies/research-involving-human-particip…) Submissions that violate this policy will be rejected. --------------------------- Reviewing Process --------------------------- All submitted papers will be reviewed by at least three members of the program committee. Research papers and tool papers will be evaluated concerning novelty, correctness, significance, readability, and alignment with the conference call. New ideas/vision papers will be evaluated primarily concerning novelty, significance, readability, and alignment with the conference call. SLEBoK papers will be reviewed on their significance, readability, topicality and capacity of presenting/evaluating/demonstrating a piece of BoK about SLE. For fairness reasons, all submitted papers must conform to the above instructions. Submissions that violate these instructions may be rejected without review, at the discretion of the PC chairs. After each review round, authors will get a chance to respond before a final decision is made. --------------------------- Artifact Evaluation --------------------------- For the seventh year, SLE will use an evaluation process for assessing the quality of the artifacts on which papers are based to foster the culture of experimental reproducibility. Authors of accepted research papers are invited to submit artifacts. For more information, please have a look at the Artifact Evaluation (http://www.sleconf.org/2022/ArtifactEvaluation.html) page. --------------------------- Special Issue --------------------------- There will be a special issue on Software Language Engineering in the Journal of Systems and Software (JSS).

Inspector #send: has vanished
by Evan Donahue July 3, 2022

July 3, 2022

Returning to Pharo after some time away and it seems the inspector API has changed a bit. In particular, I can't seem to find the #send: method that used to allow a list presenter to intercept and modify selected objects before they were displayed in the next panel of the inspector: inspectItems: aBuilder <inspectorPresentationOrder: 1 title: 'Lazy'> ^ aBuilder newList send: [ :x | 10 ] When I inspect this, I just get an error, and I can't seem to find anything resembling #send: anywhere in the presenter's class hierarchy. Does anyone know where this method has gone (Pharo 10)? Thanks, Evan

Pharo-vm mailing-list
by stephane ducasse July 2, 2022

July 2, 2022

Hi Since a couple of years the Pharo crew has been working on the Pharo-vm and most of the communication was using internal channels. Now that the community is growing we believe that it is important to have a public way to communicate around the VM and our current and future developments. We are happy to announce that we set up a mailing-list for the Pharo-vm. https://lists.pharo.org/list/pharo-vm.lists.pharo.org <https://lists.pharo.org/list/pharo-vm.lists.pharo.org> Stef on the behalf of the Pharo lille crew.

by Jesus Mari Aguirre June 27, 2022

June 27, 2022

Hello everyone! question about Mongodb and voyage... Is there any way to build a query selecting only the fields of interest just like someone asks in this question? https://stackoverflow.com/questions/43801636/specify-fields-to-return-in-vo… The answer is out of date but I think this should be supported because it is totally necessary. If it is not supported, Is this feature in your roadmap? Thanks!
