Hi Everyone, As far as I can tell, JPEGReadWriter in Pharo 7 doesn't read (or write) the image metadata, e.g. title, keywords, exposure time, etc. Is anyone aware of a package that does? Thanks! Alistair

Dear Pharo users and dynamic language lovers: We have released Pharo <https://pharo.org/> version 13! What is Pharo? Pharo is a pure object-oriented programming language and a powerful environment focused on simplicity and immediate feedback. Screenshot of Pharo 13 Image of Pharo 13 * Simple & powerful language: No constructors, no types declaration, no interfaces, no primitive types. Yet a powerful and elegant language with a full syntax fitting in one postcard! Pharo is objects and messages all the way down. * Live, immersive environment: Immediate feedback at any moment of your development: Developing, testing, debugging. Even in production environments, you will never be stuck in compiling and deploying steps again! * Amazing debugging experience: Pharo environment includes a debugger unlike anything youâve seen before. It allows you to step through code, restart the execution of methods, create methods on the fly, and much more! * Pharo is yours: Pharo is made by an incredible community, with more than 100 contributors for the last revision of the platform and hundreds of people constantly contributing with frameworks and libraries. * Fully open-source: Pharo full stack is released under MIT <https://opensource.org/licenses/MIT> License and available on GitHub <https://github.com/pharo-project/pharo> â¦ more on the Pharo Features page <http://www.pharo.org/features>.

by stephane ducasse May 29, 2025

May 29, 2025

Hi I would like to use Zinc to debug some files that Iâm generating. I do the following (ZnServer defaultOn: 7071) start. (ZnServer defaultOn: 7071) start. ZnServer default delegate: (ZnStaticFileServerDelegate new prefixFromString: ''; directory: '/Users/ducasse/Test2/Play/generated/' asFileReference; yourself) Now I get the server running (the famicon is changed) but when I do http://localhost/7071/index.html I get not found or #, was sent to nil I tried to debug the delegate but I could not find my mistake.

Survey: Identifying and Fixing Undesirable Behaviors Across Software Versions
by Remi Dufloer May 12, 2025

May 12, 2025

Hello, As part of my PhD at the University of Lille, I am currently conducting a study on how developers handle certain bug scenarios. The goal is to better understand current practices, the tools used, and developers' needs regarding debugging in a specific scenario. Link to the questionnaire: [ https://sondages.inria.fr/index.php/566958?lang=en | https://sondages.inria.fr/index.php/566958?lang=en ] Your participation in this short questionnaire (5 - 10 minutes) would greatly help us analyze existing methods and identify potential gaps in the available solutions. This survey will be open for 6 weeks (Until May 15th, 2025) . The responses will be analyzed and included in a scientific publication. The results will be available [ https://remidufloer.github.io/Dufloer.github.io/survey.html | here ] . If you can, please feel free to share this questionnaire with other developers who might be interested. Every response counts and will contribute to a better understanding of the community's practices! A big thank you for your help and time. Best regards, RÃ©mi Dufloer PhD Student, University of Lille ------------------------------------------------ ------------------------------------------------ ------------------------------------------------ ------------------------------------------------ ------------------------------------------------ Bonjour , Dans le cadre de ma thÃ¨se Ã lâUniversitÃ© de Lille, je mÃ¨ne actuellement une Ã©tude sur la maniÃ¨re dont les dÃ©veloppeurs gÃ¨rent certains scÃ©narios de bugs. Lâobjectif est de mieux comprendre les pratiques actuelles, les outils utilisÃ©s et les besoins des dÃ©veloppeurs en matiÃ¨re de debugging sur un scÃ©nario prÃ©cis. Voici le lien du questionnaire : [ https://sondages.inria.fr/index.php/566958?lang=en | https://sondages.inria.fr/index.php/566958?lang=en ] Votre participation Ã ce court questionnaire (5 - 10 minutes) nous aiderait Ã©normÃ©ment Ã analyser les mÃ©thodes existantes et Ã identifier les Ã©ventuelles lacunes dans les solutions disponibles. Ce survey est ouvert durant 6 semaines (fermeture le 15 mai 2025 ). Les rÃ©ponses obtenues seront analysÃ©es et feront l'objet d'une publication scientifique. Les rÃ©sultats seront publiÃ©s [ https://remidufloer.github.io/Dufloer.github.io/survey.html | ici ] . Si vous le pouvez, nâhÃ©sitez pas Ã partager ce questionnaire avec dâautres dÃ©veloppeurs susceptibles dâÃªtre intÃ©ressÃ©s. Chaque rÃ©ponse compte et contribuera Ã une meilleure comprÃ©hension des pratiques de la communautÃ© ! Un grand merci pour votre aide et votre temps.

Call for Participation: SLE 2025 - 18th ACM SIGPLAN International Conference on Software Language Engineering
by Andrei Chis May 8, 2025

May 8, 2025

** Call for Participation ** 18th ACM SIGPLAN International Conference on Software Language Engineering (SLE 2025) 12-13 June 2025 Koblenz, Germany https://conf.researchr.org/home/sle-2025 https://www.sleconf.org/2025/ https://x.com/sleconf ------------------------------------------------------------------------ The ACM SIGPLAN International Conference on Software Language Engineering (SLE) is devoted to the principles of software languages: their design, their implementation, and their evolution. Like its predecessors, the 18th edition of the SLE conference, SLE 2025, will bring together researchers from different areas united by their common interest in the creation, capture, and tooling of software languages. It overlaps with traditional conferences on the design and implementation of programming languages, model-driven engineering, and compiler construction, and emphasises the fusion of their communities. To foster the latter, SLE traditionally fills a two-day program with a single track, with the only temporal overlap occurring between co-located events. --------------------------- Registration --------------------------- Registration happens via the STAF registration page Early Bird Registration Deadline is May 10th, 2025 https://conf.researchr.org/attending/staf-2025/staf-2025-registration --------------------------- Venue --------------------------- University of Koblenz https://conf.researchr.org/venue/sle-2025/staf-2025-venue --------------------------- Keynotes --------------------------- * Thorsten Berger, Ruhr University Bochum, Germany A New DSL Textbook in Town! * Friedrich Steimann, FernuniversitÃ¤t in Hagen, Germany an Programming Be Liberated from the Functional Style? https://conf.researchr.org/home/sle-2025#Keynotes --------------------------- Awards --------------------------- During the conference, we will announce the following awards: * Distinguished paper: Award for the most notable paper, as determined by the PC chairs based on the recommendations of the program committee. * Distinguished artefact: Award for the artefact most significantly exceeding expectations, as determined by the AEC chairs based on the recommendations of the artefact evaluation committee. * Distinguished reviewer: Award for the programme committee member that produced the most useful reviews as assessed by paper authors. * Most Influential Paper: Award for the SLE 2015 paper with the greatest impact, as judged by the SLE Steering Committee. * COLA Award: 2024 Journal of Computer Languages Best Paper Award --------------------------- Accepted Papers --------------------------- * A Model-Driven Approach to Design, Generation, and Deployment of GUI Component Libraries Arkadii Gerasimov, Nico Jansen, Judith Michael, Bernhard Rumpe, Sebastian Will * AnyText: Incremental, left-recursive Parsing and Pretty-Printing from a single Grammar Definition with first-class LSP support Georg Hinkel, Alexander Hert, Niklas Hettler, Kevin Weinert * Boosting Parallel Parsing through Cyclic Operator Precedence Grammars Michele Chiari, Michele Giornetta, Dino Mandrioli, Matteo Pradella * Detecting Resource Leaks on Android with Alpakka Gustavo Amorim Santos, Alexandra Mendes, JoÃ£o Bispo * Dynamic Dependency-Based Purity Checking Anton Risberg AlakÃ¼la, Niklas Fors, Christoph Reichenbach * Exploratory, Omniscient, and Multiverse Diagnostics in Debuggers for Non-Deterministic Languages Damian FrÃ¶lich, Tommaso Pacciani, L.
