UK Smalltalk User Group Meeting - Wednesday, December 29th

by Giovanni Corriga

For our December meeting, Florin Mateoc will show us JsSqueak ( https://github.com/fmateoc/JsSqueak ), a JavaScript implementation of (JavaScript compiled) Squeak. Whereas SqueakJS or TruffleSqueak are implementations of the Squeak stack VM which run the Squeak bytecodes, JsSqueak compiles all the Squeak code to JavaScript (including the VM plugins), it exports the image state as one big JavaScript storeString, and then loads them, and runs the JavaScript implemented minimal VM (mostly primitives) and the JavaScript-translated Squeak methods as one combined JavaScript application. The compiled JavaScript application can be run either in a browser or in Node.js While JavaScript, especially with its newest additions, is a very powerful language, which allows us to implement most Smalltalk-specific features (e.g. processes/green threads are implemented using generator functions and recursive yield* for all invocations, DNU is implemented using proxies and proto manipulation, the Smalltalk parallel class hierarchy is implemented using JavaScript classes with static properties and their parallel prototypes hierarchy, weak classes are implemented using JavaScript WeakRef instances in their (weak) slots), one obvious challenge is implementing contexts. Since we compile Squeak classes to JavaScript classes, Squeak methods to JavaScript methods (and class-side Squeak methods to static JavaScript methods), the code runs on the native JavaScript call stack, and we do not have a mapping between the JavaScript function activations and reified contexts. Nevertheless, it turns out that, by providing specialized implementations for various aspects that are implemented using contexts/stack walking in Squeak, we can actually run almost all Squeak code as-is. Florin Mateoc ( https://fmateoc.js.org/ ) is an electronics engineer who has always loved programming and who has actually only ever worked as a software engineer. Florin has worked as a professional Smalltalk programmer in Enfin (later called ObjectStudio), VisualAge, VisualWorks, and a little bit as a hobbyist in Squeak. 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/282445345/ ) to receive the meeting details. Don’t forget to bring your laptop and drinks!

UK Smalltalk User Group Meeting - Wednesday 24 November

by Giovanni Corriga

This month, the UKSTUG will take a look at Objective-S ( http://objective.st/ ), an architecture-oriented programming language based on Smalltalk and Objective-C, by hosting his creator Marcel Weheir. 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 Weheir ( https://twitter.com/mpweiher ) 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 of the lessons learned from over a quarter century of industry experience into Objective-S. 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/cbklbryccpbgc/ ) to receive the meeting details.

UK Smalltalk User Group meeting - Wednesday, October 27th

by Giovanni Corriga

For this month's meeting, Cincom Smalltalk ( https://www.cincomsmalltalk.com/main/ ) product manager Arden Thomas will discuss recent product changes and improvements and demonstrate some tools and features of ObjectStudio and VisualWorks 9.1. Arden ( https://twitter.com/ArdenTCST ) started working with Smalltalk in 1986, looking for a better way to do software development – and he found it. Arden built factory floor layout tools for IBM, worked at ParcPlace as an SE, an instructor, and consultant, and at a hedge fund building financial analysis tools. Arden is currently the product manager for Cincom Smalltalk. This will be an online meeting from home.

UK Smalltalk User Group Meeting - Wednesday, September 29th 2021

by Giovanni Corriga

The next meeting of the UK Smalltalk User Group will be on Wednesday, September 29th. For this month's meeting, we take a look at an example of an application written in Smalltalk. Specifically, one that fits in a cultural tradition that is as old as Smalltalk itself, if not older: that of using computers as tools to teach powerful ideas and to augment thinking. Dr. Geo ( http://drgeo.eu/ ) is an interactive geometry software with programming capabilities in Smalltalk. Dr. Geo aims to be an open, easy to study, modify and extend interactive geometry software. Ten years old kids use Dr. Geo to explore Euclidean geometric sketches; agile kids extend and program it with its embedded dynamic Pharo language and user interface. Hilaire Fernandes started the development of Dr. Geo in 1996. In 1998, he ported it to GNU/Linux at a time where no interactive geometry software existed on this system. It latter became officially a GNU application blessed by Richard Stallman. In the spirit of free software and access to source code, Dr. Geo integrated scripting and programmed figure as well as code introspection from the application itself in an interactive programming environment. Hilaire currently teaches in a junior high school in Geneva where he uses Dr. Geo to teach mathematics (geometry) and basic programming. 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/cbklbryccmbdc/ ) to receive the meeting details.

[Pharo-users] Upgrade job

by stephane ducasse

Hi, We are running a seaside app on GemStone 3.4.1 and develop in Pharo 6.1. Is there someone out there who would be interested in taking on the job of upgrading both GemStone, Pharo and Seaside to recent versions? This is in our environment, with numerous databases, testing and dev environments. It would be preferable if the person (or people) understand Monticello, Metacello and Seaside packages that work together. This would be on a contract basis until the project is complete. Please contact me directly if you are interested. Kind regards Otto Behrens Otto Behrens <otto(a)finworks.biz>
