A Bare-Metal Smalltalk-80 System for the Raspberry Pi - Wednesday, January 27th

The next meeting of the UK Smalltalk User Group will be on Wednesday, January 27th. For this presentation, guest speaker Michael Engel will bring us back to basics with a bare-metal Smalltalk-80 system for the Raspberry Pi. In 2020, the Xerox PARC research laboratory celebrated its 50th anniversary. One of the most important developments coming out of PARC is the Smalltalk system, which integrates a programming language, operating system and graphical user interface. Today, most of the Smalltalk systems run in hosted mode on a conventional operating system. This contradicts Dan Ingalls' idea that "an operating system is a collection of things that don't fit inside a language; there shouldn't be one". Accordingly, original Smalltalk systems, e.g. for the Alto workstation, ran on the bare metal of the computer. In this talk, we will discuss an approach to create a bare-metal Smalltalk-80 implementation for the Raspberry Pi , a popular family of ARM-based systems. In

Moldable development with Glamorous Toolkit - Wednesday, December 30th

 The UK Smalltalk User Group will have an extra meeting this year on Wednesday, December 30th. feenk 's Tudor Girba will present the latest in moldable development with Glamorous Toolkit . Moldable development is an approach to programming through which we make the inside of software systems explainable. Glamorous Toolkit makes it practical. And beautiful. Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's  Meetup page  to receive the meeting details. Don’t forget to bring your laptop and drinks!   Update 9 January 2021 : The presentation is now up at Vimeo: Part 1 , Part 2 .

Siren9 and CSL6 - Frameworks and Applications for Sound/Music Creation and Processing - Wednesday, November 25th

The next meeting of the UK Smalltalk User Group will be on Wednesday, November 25th. Stephen Travis Pope will present Siren9 and CSL6 - Frameworks and Applications for Sound/Music Creation and Processing. The Siren system is a general-purpose software framework for music and sound composition, processing, performance, and analysis; it is a collection of about 350 classes written in Smalltalk-80 (40 kLOC or so). The current version of Siren (9.0) works on VisualWorks Smalltalk and supports streaming I/O via OpenSoundControl (OSC), MIDI, and multi-channel audio ports. The CREATE Signal Library (CSL) is a cross-platform C++ framework for digital audio signal synthesis, analysis, spatialization and interactive sound/music application development. CSL was developed at the University of California, Santa Barbara (UCSB) starting in the late 1990s. This presentation will introduce both package and demonstrate their use together to construct real-time compositional and music synthesis software

Agile Visualization with Roassal3 - Wednesday, October 28th

 The next meeting of the UK Smalltalk User Group will be on Wednesday, October 28th.  Alexandre Bergel will talk about Agile Visualization with Roassal3. Visualizing data is probably the easiest part in the field of data visualization. Numerous books and sophisticated libraries exist for that very purpose. One of challenges of data visualization is to identify the right abstractions that make a visualization reusable, composable, extensible, navigable, and produced at a very low cost. Roassal is a visualization engine for Smalltalk that leverage the experience of crafting and using data visualization. This talk will demo Roassal and presents non-trivial visualizations within the field of software visualization. Alexandre Bergel is Associate Professor and researcher at the University of Chile. Alexandre Bergel and his collaborators carry out research in software engineering. His focus is on designing tools and methodologies to improve the overall performance and internal quality of sof

AppeX: Writing JavaScript in the Cincom Smalltalk™ IDE - Wednesday, September 30th

The next meeting of the UK Smalltalk User Group will be on Wednesday, September 30th.  For this meeting, Niall Ross and Vlad Degen from Cincom will present AppeX , Cincom’s web application development framework. Together they will cover: The advantages of the AppeX design philosophy - lightweight, plays well with others How AppeX works in the Cincom Smalltalk IDE The advantages of WYSIWYG AppeX JavaScript development through debugging of running AppeX applications How you can use AppeX in the Cincom Smalltalk IDE to learn and improve your JavaScript, and to create and deploy JavaScript intensive modern web applications. The advantages of AppeX web development, using the Chrome DevTools in conjunction with AppeX for debugging. Given the current COVID-19 restrictions, this will be an online meeting from home.

CodeParadise: a better place for the next generation of coders - Wednesday, August 26th

 The next meeting of the UK Smalltalk User Group will be on Wednesday, August 26th. In this meeting, Erik Stel will present his current project - CodeParadise. CodeParadise is a cloud based platform (to be) to learn to program using Object Oriented principles within a Smalltalk environment. CodeParadise is still in very early development, but some of its results have seen interest from the community. Therefore a presentation will provide insight in the design, current status, and possibilities of the results so far. The discussion afterwards can be used for both in-depth technical topics as well as the more philosophical topics about programming (as warmth and/or beer consumption will guide us). Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's  Meetup page  to receive the meeting details. Don’t forget to bring your laptop and drinks! Update 13 September 2020 : a recording of

Deploying to the cloud from Pharo - Wednesday, July 29th

The next meeting of the UK Smalltalk User Group will be on Wednesday, July 29th. Peter Svensson will present his work on Cloudsdk-st. Cloudsdk-st is an experiment in ways to work with cloud deployment from a Smalltalk image. Traditionally cloud deployments run 'out of band' in separate build scripts or build/CI/CD systems. This project lets you define Docker images (using Dockerfiles) for Smalltalk, send them to the build system of a cloud provider directly and then choose what kind of service you want your image to be (cloud function or long-running VM). Currently it only supports Google Cloud and has a very rough UI. Future plans include support for AWS and Azure as well as better feedback and a Spec2 UI. Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page to receive the meeting details.
