Congratulations to the 2026 Squeak Oversight Board members on their election.
Thank you to all who participated as candidates and supported the process along the way. Squeak continues to thrive because of the people who contribute their time, ideas, and leadership to the community.
A special thank-you to Patrick for once again coordinating the election and guiding the process so effectively.
We are excited to work with both new and continuing board members and look forward to all that the coming year will bring.
The following is Patrick’s official announcement shared with the Squeak Developers mailing list:
Hi everyone,
I’m very pleased to announce your Squeak Oversight Board for 2026. They are:
Marcel Taeumel
Eliot Miranda
David T. Lewis
Christoph Thiede
Craig Latta
Scott Gibson
Jaromir Matas
I would like to thank everyone that served on the board in the term of 2025. Thank you for your contributions to Squeak!
Thank you to everyone that ran this year and for everyone that voted. We are looking forward to a great year in the Squeak community!
Please help me to congratulate your new board for 2026!!
The message below was shared by Patrick Rein on the Squeak Developers mailing list (link here). We encourage you to put your name forward or support a candidate by casting your vote on Squeak-dev. This is a great opportunity to take part. Now is a great time to become involved!
Hi All,
(If you plan to run, please note the important information for board members below).
It’s that time again. Time to raise your voices and elect your leaders! Can you believe it’s been over a year already?
It’s a time for you to stand up, help your community and volunteer to serve!
Squeak wants you!
Every year we elect the SOB (Squeak Oversight Board) consisting of seven members from our community. The current board members are:
Candidates should nominate themselves and start their campaign on the squeak-dev mailing list. Or if you nominate someone else, make sure that person really wants to run. 🙂 I will not put anyone on the candidate list until that person makes it known on squeak-dev that he/she intends to run.
During this period, the candidates should ideally present themselves on squeak-dev, unless they have already done so, and the community can ask questions.
I encourage you to reach out to potential candidates, people that are active in the community and represent your views, and ask them to run. Some people will not run without encouragement. Also, I know that some people wait to the last minute to run for the board to see if others will run but please consider getting this year off to a faster start and just jump right in!
The schedule and process are as follows:
Now until Friday 8th of May 2026, 18.00 UTC: Nominations of SOB members and campaigning!
Friday 8th of May 2026, 18.00 UTC: Candidate list is finalized.
Friday 8th of May 2026, ~19.00 UTC: Online election starts.
Friday 22nd of May 2026, 19.00 UTC: Online election ends.
Results will be announced immediately after the election ends.
The voting period is two weeks long and ballots are sent out via email.
And how do you end up on the voter list? See below. 🙂
IMPORTANT: New voters will not be added once the election is started. You must try to get on the voter list before the 8th of May 2026 or you will not be able to vote. If your Email has changed please try to make sure it is changed on the list of voters before the election starts.
————————–
If you were invited to vote last year you are already on the voter list, no worries! If you are a new Squeaker and wish to vote you should do one of the following:
Get a “known” Squeaker to vouch for you. If a known Squeaker sends an email to voters (at) squeak.org giving me a name and email for you, then I will add you.
Send an email to voters (at) squeak.org yourself (and CC to squeak-dev if you like) with information/arguments showing me that you are indeed serious about voting and that you are indeed a Squeaker.
When the voting period starts all voters will receive an email with instructions and a link to the voting website.
If there are any further questions, just reply *in this thread* and I will closely track it – or send email to voters (at) squeak.org which is updated and points to me.

This month marks 29 years since the birth of Squeak Smalltalk. That is nearly three decades of exploration, invention, and collaboration – all made possible by the ambition and generosity of those who have shaped Squeak over the years.
On this occasion, it is fitting to pause and give thanks:
To those who, in the early years, had the vision and energy to create something enduring.
To those who continue to share insights and encouragement, answer questions, and work to resolve difficult issues on the mailing lists, sustaining collaboration and shared purpose.
To the programmers who work tirelessly on the system and the virtual machine, ensuring that Squeak remains robust, modern, and ready for the challenges ahead.
To the maintainers who incorporate patches and merges, smoothing the flow of progress and keeping the platform healthy.
To the unsung heroes who support the infrastructure, making sure our tools and resources are available and reliable.
To the academic community at large who continues to explore, teach, and contribute to Squeak.
To those who provide financial support, helping sustain the project and its infrastructure.
And to everyone else not mentioned in this brief list.
Each contribution, whether large or small, has helped Squeak remain vibrant and resilient – a system that is both a playground for ideas and a platform for serious development.
As we look forward to the next year, let this anniversary be a moment of encouragement. There is always more to explore, more to refine, and more to create together. Your help makes a difference and keeps Squeak a programming system that is a joy to use, where everything is available to see, understand, modify, and extend for any purpose. With 30 just around the corner, now is a good time to reflect that you make a difference, and that Squeak would not continue without the efforts of its community.
Here’s to another year of invention, collaboration, and joy with Smalltalk and Squeaking!

Tony Garnock-Jones recently announced on the Squeak Developers mailing list (here) a new contribution to the Squeak community: Multicast, a project that brings UDP multicast socket support to Squeak.
The project has been published on SqueakSource (here), where you can obtain the code and experiment with it directly. Tony also provided the file-in code with his announcement.
What Does Multicast Do?
Multicast provides the necessary support code for creating and using UDP multicast sockets within Squeak. This makes it possible for Squeak images to participate in group communication over networks – an important feature for distributed applications and collaborative tools. Check out the mailing list thread for more information on what multicasting does.
Current Status and Platform Support
Tested on macOS: Initial testing has been done successfully.
Linux support: Testing is planned soon.
Windows users: Contributions are welcome – help testing Multicast on Windows would be especially valuable.
Requirements
To use Multicast, you will need:
A current Trunk version of Squeak
The SocketPlugin enabled
How to Help
Community involvement is encouraged! If you are running Squeak on Linux or Windows, testing Multicast and reporting results would be a great way to contribute.
Have a great time with Smalltalk and keep on Squeaking!
The California Smalltalkers meeting on August 13 at 7:00 p.m. PDT will feature a presentation by Craig Latta on his recent work with Catalyst, a WebAssembly GC (WASM GC) implementation of the Open Smalltalk virtual machine. Latta will share surprising results from experiments using AI models to dynamically translate Smalltalk methods into WASM functions.
The talk will also examine the historical evolution of dynamic stack machine optimization and explore BNF-level optimizations enabled by the Epigram compilation framework.
The meeting will additionally include community lightning talks, giving attendees an opportunity to highlight current projects and ideas. Participants are invited to draw inspiration from their peers, and those interested in giving a longer presentation in the future are encouraged to reach out to the organizers.
Dr. Nicola Mingotti has released a new in-depth tutorial video that explores how to identify and name Morphs in the Squeak/Smalltalk environment. If you have ever wondered how to refer to a specific Morph – for example, how to say “make that Morph yellow” – this video walks you through several effective techniques.
Throughout the video, you will learn how to use tools such as the object explorer and the workspace to better understand and interact with objects in Squeak. The tutorial introduces a variety of methods, including assigning names to Morphs, identifying them using properties such as identityHash and knownName, and inspecting objects with user interface tools that are not immediately obvious to new users.
This tutorial is particularly useful for those who wish to go beyond the basics and gain more precise control over their Squeak projects. It also includes several helpful interface tips that may be difficult to discover independently.
Let us dive into the exciting process of game creation!
In this lesson, you will begin writing the actual code that brings your game to life. The previous lessons prepared you by helping define the game’s key objects and their responsibilities. Now, with those ideas in place, it is time to create your first class in Smalltalk: ShooterGame.
This class will act as the canvas for everything else that follows. Though it may seem plain at first, much like an artist’s blank canvas, your ShooterGame Morph will soon host a lively collection of interactive game objects – ships, enemies, shots, and more. Unlike a painting, however, this canvas can respond, animate, and change as your code evolves.
Using the System Browser
The work begins in the System Browser, a powerful tool within the Squeak environment where you can write, view, and organize your code. You can open the System Browser from the main menu under Tools → Browser, or by left-clicking on the desktop background and selecting Browser.
This browser is not the only place you can write code in Squeak, but it is the one you will use most frequently as you build and modify your game. You will use it to define classes, write methods, organize your code into categories, and explore existing functionality that your objects can build on.
ShooterGame as a Morph
When you create your ShooterGame class, you define it as a subclass of Morph. This design choice is essential. A Morph is a graphical object in Squeak that can be added to the screen, moved around, colored, resized, and interacted with. By making ShooterGame a Morph, you give it the ability to appear on the screen and act as a visible, interactive container for the other game elements.
This inheritance relationship also means that ShooterGame will share the capabilities of Morphs – like positioning and drawing – while allowing you to add new, game-specific behavior through your own methods.
Understanding Initialization
After defining your class, you will write its first method: initialize. This is a special method that sets up a new instance of the class when it is created. It is also an ideal place to define how the object should appear and behave initially.
An instance of a class is the actual object that gets created from that class. Think of the class as a blueprint or a set of instructions – like the design for a computer. That design tells you what the computer will have and how it will work. But until someone actually builds a computer from that design, you do not have a real one. The same is true in programming: the class is the design, and an instance is the real, usable object created from that design. Every time you create a new object from a class, you are making a new instance of it. And because everything in Smalltalk is an object, even the class itself is a kind of object – one that can do things, not just describe them!
Inside the method, you will encounter super initialize. This line is important. It tells the system to first run the initialize behavior of the parent class – in this case, Morph – before adding your custom setup code. An initialize method should always start by sending super initialize. Skipping this line can lead to unexpected issues because it would prevent an object from preparing itself properly.
Following that, you will define the Morph’s position and size using the position: and extent: messages. In Squeak, extent refers to the width and height of the Morph – think of it as how much space it occupies on the screen. The coordinate system in Squeak starts at the top-left corner of the screen (0 @ 0), and each point is written as an x and y pair (e.g., 640 @ 480). These lines of code determine where your game window will appear and how large it will be.
You also set the background color to black and give the object a name using setNameTo:. These finishing touches help establish your game’s visual style and identity.
Positioning and Sizing
In Squeak, the World refers to the entire display area of the environment – the space where all graphical objects (Morphs) appear and interact. It is the backdrop of your development tools, your game, and the broader environment in which your game objects will live and move. Even the tools you use to write your code – such as the System Browser – are Morphs themselves, sharing the same space and able to interact with the same environment as your game.
Squeak uses a coordinate system to place and size Morphs on the screen. The top-left corner of the World is the origin (0 @ 0). When you set a Morph’s position to 100 @ 100, it will appear 100 points from the left and 100 points from the top. The extent describes the Morph’s width and height – how much space it will take up on the screen. These values give you precise control over where and how your game interface is laid out.
Seeing the Results
Even after completing just this lesson, you will be able to see the first visible result of your code. Though the game is not yet playable, the space in which it will take shape is now visible and ready for action. The foundation is laid, and every lesson from here will build upon it.
Remember that these lessons are designed for live coding – you are encouraged to run, modify, and explore your work as you go. That is one of the great strengths of Smalltalk. The lessons in this series are designed for live coding, meaning the game does not need to be closed and restarted when changes are made. You can follow through the lessons just as easily without live coding; however, you may not learn as many topics, as some only arise from using live coding. Also, remember that, unlike some other programming languages, Smalltalk does not require a final period (.) at the end of a method. The final period in the last expression is optional.
And finally, remember to save your work once you have successfully completed the lesson. This ensures you can pick up right where you left off next time or provides a good recovery option if something should go wrong.
