UKSTUG meeting - Tudor Gîrba: What exactly is Glamorous Toolkit? - 24 April 2024
by UK Smalltalk 22 Apr '24

22 Apr '24

To some people Glamorous Toolkit is a Pharo environment. To others it’s a knowledge management system. Others might see a code analysis platform, a data visualization or an API browsing tool. Yet others see the graphical stack with its interactive editors. Glamorous Toolkit is all of these. But it’s really also none of these. These are merely examples of the many forms the environment can be molded to. And there can be many more. Glamorous Toolkit is primarily an environment that makes it possible to create many experiences seamlessly and contextually. This then leads to a new way of programming that we call Moldable Development. Tudor Gîrba is a software environmentalist and the CEO of feenk.com ( http://feenk.com/ ) where he works with an amazing team to make the inside of systems explainable. Much of the work is embodied in Glamorous Toolkit ( gtoolkit.com), a novel environment that enables moldable development. This will be an online meeting from home.

UKSTUG Meeting 28 February 2024: Juan Vuletich - Bootstrap & Dynamic Cuis Libraries
by Giovanni Corriga 23 Feb '24

23 Feb '24

Juan Vuletich returns to the UKSTUG to discuss some recent enhancements to Cuis Smalltalk ( https://cuis.st/ ) : Bootstrap and Dynamic Cuis Libraries. Bootstrap: Creating Minimal Images from Scratch > * The last ancestor of Cuis Smalltalk that was bootstrapped from scratch was Smalltalk-76. Since then, various released images of Smalltalk-80, Squeak and Cuis were derived by applying updates to the previous one. A new tool called 'Bootstrap' allows the creation of minimal Smalltalk images from scratch. These images are in the Spur 32 and 64-bit formats, compatible with the OpenSmalltalk VM. 'Bootstrap' gives developers complete control over what is included in the new image. It is compact, relatively simple, and easy to extend and adapt. Dynamic Cuis Libraries: A binary format for Cuis code that is powerful and quick to load > * Dynamic Cuis Libraries are binary files with pre-compiled code that can be loaded into a running Cuis image. They can add new classes and extend existing ones. For existing classes, there are no requirements on the shape of that class in the image loading the library. Missing variables are added, extra variables are kept, and both existing and newly loaded methods are adjusted to whatever shape the class has. Juan Vuletich ( https://independent.academia.edu/JuanVuletich ) is the founder and lead developer of Cuis Smalltalk. He is a long-standing Open Source Smalltalk community member, having contributed kernel code to Cuis, Squeak and the Squeak VM for over 25 years. Juan has been programming since he was 14, and doing it professionally since he was 17. He holds an MS.Sc. in Computer Science from the University of Buenos Aires. He works at LabWare. This will be an online meeting from home.

UKSTUG Meeting - Pierre Misse-Chanabier: Polyphemus Take 2 - 31 January 2024
by Giovanni Corriga 26 Jan '24

26 Jan '24

Pierre Misse-Chanabier will talk to us about Polyphemus ( https://github.com/hogoww/Polyphemus ) for the Pharo Virtual Machine. The presentation will focus on how to create Tooling on the Pharo Virtual Machine. (This does not require Virtual machine level knowledge). We will start by taking a look at a few existing tools. We will create one or two small tools, and see how they differ from tooling on the image side. Pierre Misse Chanabier is a recently graduated PhD with a focused interest on Virtual Machines, Code Generation, and Meta Programming. He worked on and contributed to many different levels and parts of the Pharo ecosystem. He is now working on how to leverage images for more than what they do now. He's currently working at Microdoc ( https://www.microdoc.com ) on the Graal VM. Born in south of France, he currently lives in Lille. This will be an online meeting from home. This is a repeat of last November's presentation that could not go ahead due to issues with our Zoom account. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/298169915/ ) to receive the meeting details.

UK Smalltalk User Group Meeting: David Buck - Beagle Smalltalk, 28 June 2023
by Giovanni Corriga 26 Jun '23

26 Jun '23

For the UKSTUG June meeting, Simberon's David Buck will present Beagle Smalltalk. Over the past 8 years, David has been developing a Smalltalk virtual machine and image. He used it to release two Smalltalk games which ran on Android and iPhone devices. More recently, he's re-written the VM to use a new bytecode set and re-written the Smalltalk compiler with a new framework to make a new Smalltalk environment called Beagle Smalltalk named after the ship that took Darwin on his voyage of discovery. David plans to release this as an open-source Smalltalk to help and encourage kids to explore the world of programming. In this talk, David presents the current status of the project and where he hopes to go with it. David Buck is the president of Simberon ( http://simberon.com/ ) - a company that has been providing Smalltalk training and consulting for over 25 years. Along with James Robertson, David produced the Industry Misinterpretations podcast and later the Smalltalk Reflections podcast with Craig Latta. David remains a Smalltalk enthusiast and works to spread the word about Smalltalk. This will be an online meeting from home.

UK Smalltalk User Group meeting - 31 May 2023
by Giovanni Corriga 31 May '23

31 May '23

For our May presentation, Stephane Ducasse will present the vision behind Pharo and how that is been implemented incrementally across multiple releases. In Stef's words: "The vision of Pharo is based on three pillars: - First we want to make sure that Pharo is used to develop complex and robust systems (by complex we means multiple millions lines of code or objects). - Second we want Pharo to be a modular system that can be versatile (Pharo on iot, on large servers, in the web browser….) - Third Pharo should be an evolvable system that can adapt to new needs (modular tools, first class slot, new debuggers, packages…). Sometimes it can be unclear that we follow this vision but over the years we are delivering this vision and we will continue. In this talk I will briefly recall the vision behind Pharo and show the achievements so far. I will show that our development is heavily backed by tests. In the second part of the talk I will focus on the current effort to improve the user interface. I will show that the reimplementation of the Spec UI framework is a cornerstone of the future replacement of Morphic and use of GTK. I will also answer questions about Pharo 11 and Pharo 12." Stephane is an Inria Research Director, currently lead the RMoD team ( http://rmod.lille.inria.fr/ ). Stef is an expert in language design, software quality, program understanding, program visualisations, reengineering and metamodeling. Among his contributions we can list: traits (implemented in Pharo, Perl, PHP and other languages); Moose, an open-source software analysis platform ( http://www.moosetechnology.org/ ). Stef is one of the leaders of Pharo ( http://www.pharo.org/ ), a dynamic reflective object-oriented language supporting live programming, and of the industrial Pharo consortium ( https://consortium.pharo.org/ ). Stef works regularly with companies such as Thales, Wordline, Siemens, Berger-Levrault, Arolla, and others on their software evolution problems. Stef has authored a couple hundred articles ( http://stephane.ducasse.free.fr/Publications.html ) and several books ( http://books.pharo.org/ ). This will be an online meeting from home.
