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 theRMoD team. 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. Stef is one of the leaders ofPharo, a dynamic reflective object-oriented language supporting live programming, and of the industrialPharo consortium.
Stef works regularly with companies such as Thales, Wordline, Siemens, Berger-Levrault, Arolla, and others on their software evolution problems. Stef has authored acouple hundred articlesand severalbooks.

WebAssembly (WASM) is an instruction format for portable high-performance code, run by a stack-based virtual machine. To Smalltalkers, this sounds very familiar. WASM is supported by the three most popular web browsers, and by other host platforms as well. Perhaps we can translate certain Smalltalk compiled methods to WASM, augmenting our support for physical processors and for livecoding the Web. For our February meeting, Craig Latta will describe his initial experiments, using the Epigram compilation framework. Craig Latta is a research computer scientist in Berkeley and Amsterdam, with interests including livecoding, music performance, and interactive visualization. The discovery of a mysteriously-placed copy of the Blue Book at university led to stints at several exploratory labs, and a pursuit of improvisation wherever code is found.

The next meeting of the UK Smalltalk User Group will be on Wednesday, March 31st. In this meeting, Juan Vuletich will present a Vector Graphic implementation in Cuis Smalltalk. Graphics for interactive software have traditionally been constrained for performance reasons. The consequence is that most software has serious trouble adapting to higher resolution screens, requires platform specific widget kits, provides limited functionality, and has sub optimal visual quality. But improvements in computing power over the last couple of decades enable a brighter future: Cuis Smalltalk provides a VectorGraphics based implementation of the Morphic UI framework that addresses all these issues. Juan Vuletich is a long standing member of the Open Source Smalltalk community. He started Cuis Smalltalk 12 years ago and has led it ever since. He has been contributing kernel code to Squeak and the Squeak VM for over 20 years. He holds an Ms.Sc. in Computer Science from the University of Buenos Air
In order to welcome Michael Lucas-Smith and Helge Nowak, who will be visiting London this month, we've moved our November monthly meeting one week earlier to Monday, November 22. Michael has offered to give us an in-depth presentation on Xtreams , a streaming framework with a new and refreshingly consistent API. From the project page: Xtreams is a generalized stream/iterator framework providing [a] simple, unified API for reading from different kinds of sources and writing into different kinds of destinations (Collections, Sockets, Files, Pipes, etc). Streams themselves can be sources or destinations as well. This allows to stack streams on top of each other. It is the stacking nature of the streams that give this framework its real power and, from what Michael and Martin (Kobetic) have shown me, you can do some pretty impressive stuff. Martin's presentation at ESUG only scratched the surface, apparently, and Michael intends to delve even deeper. There will also be plenty of ti
