Vector Graphics in Cuis Smalltalk - Wednesday 31st March

By

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 Aires.


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 17 April 2021: Part 1,  Part 2 , and Part 3 of the presentation is now available on Vimeo.

TruffleSqueak: A Squeak/Smalltalk System for the GraalVM - Wednesday, June 24th

By gcorriga
The next meeting of the UK Smalltalk User Group will be on Wednesday, June 24th. Fabio Niephaus  will talk to us about TruffleSqueak , a Squeak/Smalltalk VM and Polyglot Programming Environment for the GraalVM . He is a Ph.D. student within the Software Architecture Group  at the Hasso Plattner Institute, University of Potsdam, Germany. He has strong interests in dynamic programming languages, virtual execution environments, and software development tools. Fabio will talk about the motivation for his research in the field of Polyglot Programming. With a live demo, he will show how TruffleSqueak can be used as a polyglot IDE for other languages such as Java, Javascript, Python, R, or Ruby. He will also introduce us to the GraalVM ecosystem and discuss his experience in writing a Smalltalk VM in Truffle, GraalVM's language implementation framework. 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 advanc

Craig Latta - WebAssembly as a Smalltalk Compilation Target (v1) - 22 February 2023

By
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. 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 th

A Tour of Architectural Abstraction with Objective-S - Wednesday, November 24th

By
This month, the UKSTUG will take a look at Objective-S , an architecture-oriented programming language based on Smalltalk and Objective-C, by hosting his creator Marcel Weiher. As per Alan Kay, “Code seems large and complicated for what it does” . Objective-S addresses one source of this accidental complexity: using software architectural abstraction to directly expresses the much wider variety of architectural styles typical of modern software systems, compared to traditional programming languages that still follow the call/return architectural style of scientific programs from the early days of computing. Marcel Weiher started his forays into dynamic object-oriented computing by implementing Objective-C on his Amiga 35 years ago and hasn’t stopped since. Stops on the way have been at Apple, the BBC, Microsoft and various startups, as well as contributing to Squeak. He is currently a principal software engineer at Citymapper and PhD student at HPI, where he is trying to distill some
