UK Smalltalk User Group meeting - Wednesday, January 27th
by Giovanni Corriga 15 Jan '21

15 Jan '21

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 ( https://www.raspberrypi.org/ ), a popular family of ARM-based systems. Interesting aspects that will be investigated are the overhead involved in bringing the system to life and debugging it, adapting the system to different Raspberry Pi models, and constraints due to properties of the hardware and the Smalltalk-80 VM. Michael Engel ( https://multicores.org/ ) is associate professor for compiler design at the Norwegian University of Science and Technology (NTNU) in Trondheim/Norway. His research interests lie on the intersection of compilers, operating systems and modern hardware. In previous positions, Michael worked at different German Universities as well as Oracle Labs Cambridge and Leeds Beckett University. He also was founder and CTO of kernel concepts, the first German company working with embedded Linux systems in 1999. Given the current COVID-19 restrictions, this will be an online meeting from home.

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 ( https://www.meetup.com/UKSTUG/events/275119813/ ) to receive the meeting details.

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 ( https://github.com/stpope/Siren9 ) 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)( https://github.com/stpope/CSL6 ) 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. Stephen Travis Pope ( http://heaveneverywhere.com/stp ) is an award-winning composer, film-maker, computer scientist and social activist based in Santa Barbara, California. He is currently active as a software development contractor and intellectual property expert through FASTLab. His music and video compositions are released through HeavenEverywhere Media. Stephen has used the Smalltalk programming system since 1984 and made several significant contributions to it, though he remains frustrated by programming environments in general. 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 ( https://www.meetup.com/UKSTUG/events/cbklbrybcpbhc/ ) to receive the meeting details.

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 ( https://github.com/ObjectProfile/Roassal3 ) 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 ( http://bergel.eu/ ) 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 software systems, by employing profiling, visualization, and artificial intelligence techniques. Alexandre Bergel has authored over 140 articles, published in international and peer reviewed scientific forums, including the most competitive conferences and journals in the field of software engineering. Alexandre has participated to over 140 program committees of international events. Alexandre has also a strong interest in applying his research results to industry. Several of his research prototypes have been turned into products and adopted by major companies in the semi-conductor industry and certification of critical software systems. Alexandre is member of the editorial board of Empirical Software Engineering. Alexandre authored the book Agile Artificial Intelligence in Pharo, Agile Visualization ( http://agilevisualization.com/ ), and co-authored the book Deep Into Pharo. Given the current COVID-19 restrictions, this will be an online meeting from home.

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 https://www.meetup.com/UKSTUG/events/cbklbrybclbjc/ to receive the meeting details. Don’t forget to bring your laptop and drinks! Cheers, Giovanni

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 (https://github.com/psvensson/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 https://www.meetup.com/UKSTUG/events/cbklbrybckbdc/ to receive the meeting details. See you there!
