Smalltalk is one of those programming languages that's lived out of the mainstream, but often referenced as an influence and an important part of programming history. It's the cornerstone of object-oriented programming, it was into message passing before actors were cool, and it blurs the line between operating system, programming language and personal notebook. But what is it? Joining us to discuss it is Juan Vuletich, the creator of one of Smalltalk's latest incarnations, Cuis. In this episode we cover Smalltalk's history, its design ideas, Cuis's unique implementation and what makes this modern implementation something special. Smalltalk is over 50 years old, but its vision of how computing could work has only begun. Let's see if we can mine some ideas from it to take us into the next generation of computing... -- The Cuis Smalltalk Book: https://cuis-Smalltalk.github.io/TheCuisBook/Preface.html Cuis on Github: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev The Cuis Community: https://cuis.st/community A Short History of Cuis: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/master/Documentation/CuisHistory.md Monticello VCS: https://wiki.squeak.org/squeak/1287 Juan's Music Research: https://www.jvuletich.org/research.html Back to the Future - The Story of Squeak (pdf): https://dl.acm.org/doi/pdf/10.1145/263700.263754 Kris on Mastodon: http://mastodon.social/@krisajenkins Kris on LinkedIn: https://www.linkedin.com/in/krisjenkins/ Kris on Twitter: https://twitter.com/krisajenkins
