Amber with Silk - Wednesday, February 24th

 The next meeting of the UK Smalltalk User Group will be on Wednesday, February 24th.   Christian Haider will guide us in a tour of the Amber dialect of Smalltalk and its Silk web framework. In his own words... Amber , created by Nicolas Petton, is a Smalltalk implemented in JavaScript running in a web browser. Silk , written by the Amber maintainer Herby Vojčík, is a web framework in Amber.    I was looking for a good solution for the web for a long time. At the last ESUG, I was bugging everybody about a Smalltalk in the browser, because I decided to redo the frontend of my current project in Smalltalk instead of JavaScript. There were some developments, but only Amber was available. So I tried it for real on a little side project ( sources ) to see if this route is viable - spoiler: it is!   Silk, the web framework, caught my attention and I fell in love with it. Silk is very simple, straight forward and powerful, just the properties I love Smalltalk for. A Silk is basically a faca

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
