What if you could define a data model, load data into it, query it, test it, visualize it, and reshape it — all without ever stopping the program? Pharo is an open-source dynamic programming language and environment in the tradition of Smallltak. Everything is a live object, the environment is a single running world you interact with continuously.

This talk introduces Pharo to an audience that may never have heard of it. Rather than a language tutorial, it is a tour of what liveness makes possible when applied to data-oriented problems. First, we will see a hand-on tutorial of Pharo Programming Environment itself, where programs are manipulated as live object. Then, we will present two real-world projects illustrating the range: Moose, a platform for software and data analysis where you interactively build custom analyses over large models and Phausto, a live coding environment where you compose synthesizers and effects as live objects and hear the results instantly.

Attendees will leave with a concrete understanding of what "live programming" means in practice, why it matters for anyone who works with data and models, and how to get started with Pharo.
