UKSTUG Meeting: AgustÃn MartÃnez - DiÃ¡logo: A Drawing-Based Programming Environment for Kids, Built in Cuis Smalltalk - 29 April 2026
by UK Smalltalk April 20, 2026

April 20, 2026

DiÃ¡logo ( https://dialog.ar/ ) is a desktop tool that lets children aged 10â17 create their own videogames by combining drawn characters with a set of visual icons â 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 DiÃ¡logo. I'll give a demo of the app, walk through some implementation metrics, and discuss the pedagogical ideas behind the project â 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). AgustÃn MartÃnez is a developer and researcher at the Universidad de Buenos Aires (UBA), and the creator of DiÃ¡logo, a programming environment for children built in Cuis Smalltalk. He presented a paper on DiÃ¡logo 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 â 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 â whether as a user, contributor, or partner â 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.

"Example of Describing Spec Application Behaviour with Hera" â New blog post on all: objects all: theTime
by Koen De Hondt April 13, 2026

April 13, 2026

Dear Pharo users and developers, I posted the fourth and final article in the series about describing Spec application behaviour with Hera. The first post explained how Hera manages open Spec windows. The second post explained how Hera identifies presenters so they can be referenced in Gherkin scenarios. The third post explained how Hera expresses steps to interact with Spec presenters. This final post includes an example that ties everything together. https://all-objects-all-the-time.st/#/blog/posts/23 As always, all feedback is welcome. Happy reading! Ciao, Koen

IWST extended abstract
by Steffen MÃ¤rcker April 11, 2026

April 11, 2026

Dear all! Maybe you can help me with this, although it is not a Pharo-question: When submitting to IWST, an extended abstract has to be provided. As far as I understand, an extended abstract should use the CEURART template. Does this mean, that it is essentially a mini-paper with sections and references or shall it be fitted into the abstract environment only? Maybe there is an example I am not aware of. Thanks and kind regards! Steffen

https://soogle.org - SmallTalk only searches for source packages and video
by Aaron Wohl April 5, 2026

April 5, 2026

When learning a new language, I like to read existing code. https://soogle.org collection uses various free (GitHub, walk-specific sites) and paid ($40/month: https://serpapi.com/) sources to collect data. An expensive Anthropic opus-4-6 reviews sampled input and makes up instructions for cheap Anthropic claude-haiku-4-5 check of input to filter out stuff like "Smalltalk how to get a date" and "And Pascal is better than Smalltalk.". open source https://github.com/avwohl/soogle
