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
