UKSTUG Meeting: Agustín Martínez - Diálogo: A Drawing-Based Programming Environment for Kids, Built in Cuis Smalltalk - 29 April 2026
by UK Smalltalk April 20, 2026

April 20, 2026

Diálogo ( https://dialog.ar/ ) is a desktop tool that lets children aged 10–17 create their own videogames by combining drawn characters with a set of visual icons — no typing required. The icons compose like cards, activating behaviours in the drawn objects and naturally leading kids through concepts such as categories, rules, recursion, and metaprogramming. In this talk I'll show how Smalltalk's live, image-based environment made it uniquely suited for building Diálogo. I'll give a demo of the app, walk through some implementation metrics, and discuss the pedagogical ideas behind the project — including a free 7-class course I've shared online and workshops I've run open to the community at the Faculty of Exact Sciences (UBA). Agustín Martínez is a developer and researcher at the Universidad de Buenos Aires (UBA), and the creator of Diálogo, a programming environment for children built in Cuis Smalltalk. He presented a paper on Diálogo at the Onward! track of OOPSLA, and has given public talks at Nerdearla, Argentina's largest tech community event. 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/314323562/ ) to receive the meeting details.

GemTalk Systems has been acquired by Emergence
by James Foster April 15, 2026

April 15, 2026

To our customers and community, As many of you recall, in 2013 Dan Ware formed GemTalk Systems LLC and acquired the GemStone product and team from VMware. After more than a decade of careful stewardship, Dan has navigated GemTalk into a strong position — and has now taken a significant next step by completing the sale of GemTalk Systems to Emergence, a private/permanent equity firm. The new owners share our commitment to GemStone/S and to the community that has grown around it. They are actively investing in the next generation of engineers to support the existing product while building the tools that will carry GemStone forward for decades to come. For existing customers, you can expect continuity in your relationships, support, and the quality of service you've come to rely on. If you are interested in the opportunities that come with this new chapter — whether as a user, contributor, or partner — we'd love to hear from you. We'll also have a number of people and presentations at ESUG in July (Plovdiv, Bulgaria), and look forward to sharing more about the plans in person. Thank you for being part of this community. Please don't hesitate to reach out with any questions.

[IWST'26] Call for Presentations
by Guillermo Polito March 30, 2026

March 30, 2026

Dear all, Submissions are now invited for the International Workshop on Smalltalk Technologies (IWST 2026), to be held in conjunction with ESUG. IWST serves as a forum for the presentation and discussion of work related to Smalltalk and closely related technologies, covering both research contributions and practical experiences. The workshop emphasizes interaction and is particularly well suited for presenting work in progress, emerging ideas, and experience reports. Topics of interest include, but are not limited to: * code analysis, testing, and debugging * compilers, virtual machines, and language implementation * tools, frameworks, and libraries * meta-programming, refactoring, and design patterns * industrial experience and case studies * integration with other languages and ecosystems Submissions for presentation take the form of extended abstracts (up to 2 pages). This allows authors to present ongoing or preliminary work without requiring a full paper at this stage. In addition, presentations of relevant work published within the past two years are welcome. Authors of accepted contributions will be invited to submit an extended version (short or full paper) for inclusion in the post-workshop proceedings. **Important dates:** * Extended abstract submission deadline: March 20, 2026 (AoE) Submissions should be made via EasyChair: https://easychair.org/conferences/?conf=iwst2026 Further details are available in the full call for submissions: https://conf.researchr.org/track/iwst-2026/iwst-2026-papers#Call-for-Submis… Kind regards, Guille, Gordana and Nahuel

UKSTUG Meeting: The VAST Platform AI Assistant: Integrating LLMs into a Live Smalltalk Environment - 25 March 2026
by UK Smalltalk March 18, 2026

March 18, 2026

Smalltalk environments have long been pioneers in developer productivity. With the VAST Platform AI Assistant, Instantiations is extending that tradition by integrating Large Language Models (LLMs) directly into the VAST platform. This new tool is designed to bring AI capabilities directly into your daily workflow. In this session, Johan, Kris, and Mariano will share a user experience report and a live demonstration of the assistant’s current capabilities, powered by Google’s Gemini. You’ll see how it goes beyond simple chat by directly interacting with the live VAST image through the LLM’s “tools” capabilities. This allows investigating source code as it responds to your questions. These examples will demonstrate how the VAST Platform AI Assistant leverages the live nature of Smalltalk to act as a true pair programmer. We’ll also look ahead at our enterprise-focused roadmap, including support for local models to ensure privacy and security, integration with additional LLM providers, and our vision for deeper IDE-level capabilities and Runtime Intelligence. Join us to explore how we are shaping the future of AI-assisted development in VAST to better empower software developers. See it in action, try it out, and join the conversation on GitHub ( https://github.com/instantiations/VAST-Platform-AI-Assistant ). Johan Brichau ( https://be.linkedin.com/in/johanbrichau ) is a seasoned software engineer with over 25 years of experience across a wide range of Smalltalk environments. He joined the VAST Platform development team at Instantiations in January 2025. Prior to that, he spent nearly 15 years as co-founder and CTO of Yesplan, a world-leading online venue management platform. Johan holds a PhD in computer science from the Vrije Universiteit Brussel (2005) and has actively contributed to several open source projects. Kris Gybels recently joined Instantiations to work on the VAST Platform’s AI-based tool support. He previously spent a number of years in academia researching Declarative Meta Programming and its application to Aspect-Oriented Programming, and over a decade co-developing the Yesplan venue management system, during which he made a number of contributions to Pharo, most notably Pharo 12’s improved Mac ‘Retina display’ support, as well as to Seaside and its Parasol web testing framework. Mariano Martinez Peck ( https://ar.linkedin.com/in/mariano-martinez-peck ) is a systems engineer specializing in dynamic programming language software. In 2018, he joined Instantiations to further develop the VAST Platform through the addition of new frameworks, libraries and tools, as well as improving the existing code base of VAST. He is active in the Smalltalk development community, and has used his expertise to co-author numerous open source projects. Mariano has a PhD in Computer Science, and his academic research has been published across various international journals. In addition to his development duties, he currently leads the VAST Platform engineering team at Instantiations. In his personal time, Mariano enjoys traveling as well as outdoor activities like camping and fishing. 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/313492185/ ) to receive the meeting details.
