DevEx survey
by stephane ducasse Nov. 14, 2025

Nov. 14, 2025

Hello people Sorry this is survey in french for developers, but it can interest french speaking developers. Bonjour, Pas plus de 5 min de votre temps! Je me permets de vous contacter afin de vous proposer de mener, au sein de vos équipes, une réplication de l’étude DevEx in Action, conduite en 2024 par N. Forsgren (Microsoft Research), E. Kalliamvakou (Github Next), A. Noda (DX), M. Greiler (DX), E. Houck (Microsoft) et M.-A. Storey (Université de Victoria). Article original disponible à https://queue.acm.org/detail.cfm?id=3639443 Cette réplication s’inscrit dans le cadre de ma thèse portant sur l’impact réciproque de la dette technique sur la santé mentale des développeurs. L’objectif de cette étude est d’évaluer l’expérience développeur (DevEx), qui définit la qualité de l’expérience vécue par les développeurs et développeuses dans leur environnement technique et organisationnel. L’étude s’appuie sur trois dimensions principales : les boucles de retour (feedback), la charge cognitive et la capacité à maintenir sa concentration. La réplication consiste à mesurer ces dimensions et leur impact sur les résultats perçus au niveau individuel, de l’équipe et de l’entreprise. Le dispositif repose sur un questionnaire unique et identique à celui de l’étude originale. Il est anonyme, volontaire et prend environ 5 minutes à remplir. Les réponses sont analysées par modélisation PLS-SEM (via SmartPLS 4), comme précisé dans l’étude originale. Lien du questionnaire : https://annac.limesurvey.net/422315?lang=fr Cordialement, Anna Cathelineau anna.cathelineau(a)gmail.com <mailto:anna.cathelineau@gmail.com>

by stephane ducasse Nov. 13, 2025

Nov. 13, 2025

Dear Smalltalk friends Please find the following conference call for papers that can interest you. If you know other forums that could be interested in virtual machines, compilers …. do not hesitate to forward this call. S. Ducasse and C. Scholliers PC chair of MPLR 26 ################################################################################## The 23rd International Conference on Managed Programming Languages & Runtimes (MPLR, formerly ManLang, originally PPPJ) is a premier forum for presenting and discussing novel results in all aspects of managed programming languages and runtime systems, which serve as building blocks for some of the most important computing systems in use, ranging from small-scale (embedded and real-time systems) to large-scale (cloud-computing and big-data platforms) and anything in between (desktop, mobile, IoT, and wearable applications). https://2026.ecoop.org/home/mplr-2026 Important Dates --------------- - Abstract Submission Deadline: February 27, 2026 - Paper Submission Deadline: March 6, 2026 - Paper Author Notification: April 15, 2026 - Camera Ready for Papers: April 30, 2026 - Conference Date: June 29, 2026 All deadlines are 23:59 AoE (UTC-12h). #### Topics The areas of interest related to managed programming languages and runtime systems include but are not limited to: - **Virtual Machines** - Portable intermediate representations (e.g., JVM, WebAssembly, RPython, ...) - Managed runtime systems (e.g., GraalVM, Android Runtime (ART), V8, JavaScriptCore, .NET, …) - VM design and optimization - VMs for mobile and embedded devices - VMs for real-time applications - Memory management and garbage collection - Hardware/software co-design - Domain-specific languages - Security and privacy - Persistence - **Languages and Compilers** - Managed languages - Compilers and interpreters - Type systems and program logics - Language interoperability - Parallelism, distribution, and concurrency - **Techniques, Tools, and Applications** - Static and dynamic program analysis - Testing and debugging - Simulation - Refactorings - Program synthesis - Performance analysis and monitoring - Compiler and program verification and model checking If you are unsure whether a particular topic falls within the scope of MPLR ’26 or if you have any other questions, please do not hesitate to contact the Program Chair. #### Submission Categories MPLR accepts three types of submissions: - **Regular research papers**, describing novel contributions involving managed language platforms. Research papers will be evaluated based on their relevance, novelty, technical rigor, and contribution to the state-of-the-art. (Format: up to 12 pages, excluding bibliography and appendix); - **Work-in-progress research papers**, describing hot topics or promising new ideas, with perhaps less maturity than full papers. Work-in-progress papers will be evaluated with an emphasis on novelty and the potential of the new ideas instead of technical rigor and experimental results. (Format: up to 6 pages, excluding bibliography and appendix); - **Industry and tool papers**, presenting technical challenges and solutions for managed language platforms in the context of deployed applications and systems. Industry and tool papers will be evaluated on their relevance, usefulness, and results. Suitability for demonstration and availability will also be considered for tool papers. (Format: up to 6 pages, excluding bibliography and appendix; up to 12 pages allowed if justified by the content); Accepted submissions will be published in the ACM Digital Library, except if the authors prefer not to be included. MPLR 2026 submissions must conform to the ACM Policy on Prior Publication and Simultaneous Submissions and to the SIGPLAN Republication Policy. See http://www.sigplan.org/Resources/Policies/Republication #### Author Instructions Submissions need to use the ACM SIGPLAN format with the `sigplan` style. If you are using LaTeX, submissions need to use the `acmart` document class with the `sigplan` option (*not* the `sigconf` option). In the `acmart-primary.zip` file that downloads from the LaTeX (Version 1.90) link on the https://www.acm.org/publications/proceedings-template page, look for `samples/sample-sigplan.tex` as a guide. If you use Overleaf, be sure to change the `documentclass` option `manuscript` to `sigplan`. For ease of reviewing, please include page numbers in your submission using the LaTeX command `\settopmatter{printfolios=true}`. Please use the standard setting, e.g., the default font size for the SIGPLAN style is 10 point and the format uses two columns for the test. All submissions need to be in PDF format. MPLR now uses **double-blind reviewing**. **Authors should not show their names on a submission and should refer to their own work in third person.** We further recommend that they avoid publicizing the work, at least under the same or similar title, while it is under review. 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://mplr26.hotcrp.com

Oct. 30, 2025

Hello Pharoers Today I just learned that Vanessa Freudenberg passed away. And I’m super sad. I knew her from Squeak Central, Impara and the funny Plop Project. Vanessa pushed SqueakJS and more projects. At ESUG this year we had fun with the new version of Plop. I do not have contact with her family and friend but I want to express my sincere condolences. Please pass them this message if you get in touch with them. S.

Re: [vwnc] JNIPort - is there anyone willing to maintain it?
by Joachim Geidel Sept. 25, 2025

Sept. 25, 2025

Dear Thomas, I definitely do not see the maintenance of JNIPort as enhancing Cincom’s products. You wouldn’t consider writing an open source application running on MS Windows or an open source library for developers who are working on Windows being an „enhancement“ of Windows, thus benefiting MS, or would you? While Cincom was so kind to including it as a contribution in the VisualWorks distribution, it has also been available for Dolphin Smalltalk, Pharo, and VASt in a long time. JNIPort has always been developed completely independently from any of the companies offering Smalltalk IDEs. JNIPort works on VW 8.3, as far as I know, so there’s no work to be done at all for making it work for VWNC users. But even if VWNC is no longer actively supported by Cincom, there may still be Cincom customers who are interested in using JNIPort on one of the more recent VisualWorks versions, and who could have an interest in adapting it to that version. In such a case, a JNIPort user’s contribution in the form of an update would be uploaded directly to the Cincom public repository. I don’t see how this would mean „a lot of time and effort“ for a potential maintainer of JNIPort apart from updating some small parts of the JNIPort documentation. And then, there’s Pharo, which has an active community, and which I suspect to have more active users now than Cincom Smalltalk. Migrating JNIPort to Pharo 14 with some help from the Pharo community shouldn’t be a lot of work. I am simply looking for someone willing to keep the strings together and to prevent that JNIPort accidentally disappears, not someone who invests a lot of time and effort in active development. My ideas about the maintainer’s role: Someone wants to use it, work has to be done to make it work, so they do it themselves and tell the maintainer about it, who then updates the docs. Google switches off Google Sites - the maintainer moves the documentation to another place. And that’s more or less it, unless the maintainer wants to have some fun with enhancing JNIPort for some reason, just as I did when I ported it to VW and Pharo just because I thought that might be interesting and fun (and it was).

JNIPort - is there anyone willing to maintain it?
by Joachim Geidel Sept. 24, 2025

Sept. 24, 2025

Dear fellow Smalltalkers, JNIPort is an interface from Smalltalk to the Java VM which was originally developed by Chris Uppal for Dolphin Smalltalk. It enables Smalltalk applications to use software written in Java seamlessly, locally and with low overhead, without resorting to network based interfaces like e.g. using microservices. Documentation is at https://sites.google.com/site/jniport/. I have ported JNIPort to VisualWorks and Pharo, and Ben van Dijk, Adriaan van Os and Rolf van der Vleuten have ported it to VASt (https://vastgoodies.com/projects/JNIPort) The last time I really worked on JNIPort was in 2014, if I remember correctly.

UKSTUG Meeting: Esteban Lorenzano - Pharo 13 - 24 September 2025
by UK Smalltalk Sept. 23, 2025

Sept. 23, 2025

Earlier this year, the Pharo development team announced the availability of Pharo 13 ( https://pharo.org/news/2025-05-21-pharo13-released.html ). For our September 2025 meeting, Pharo's release manager Esteban Lorenzano will give us a tour of the new version - what's changed, and what remains the same. Esteban Lorenzano ( https://github.com/estebanlm ) studied Computer Sciences at Universidad de Buenos Aires, and worked since 1994 in several object-oriented and low-level technologies, in different software companies, serving in various positions from programmer to senior architect. In 2007 he co-founded Smallworks to offer Pharo-based agile development projects. Since 2012 he dedicated full time to developing the Pharo code and community. He works with the INRIA-EVREF team in Lille, France, as core developer for Pharo, being responsible with the coordination of new releases and the implementation and maintenance of several Pharo libraries. This will be an online meeting. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/310635970/) to receive the meeting details.
