**Carlos Ortega** **“La ecuación de Gray-Scott y una historia de Codex-coding”** Se presentará una solución en **R** del modelo Gray-Scott, construida con **Shiny** y desarrollada de forma interactiva con un **LLM mediante Codex**. El proyecto combina simulación, visualización y experimentación en una demo muy vistosa y fácil de explorar. Una propuesta ideal para descubrir una forma distinta de crear y prototipar con R. **Francisco J. Rodríguez** **“Movimiento LunaR y eclipses con R”** En esta charla se hace una **introducción a los eclipses y qué algoritmos están implementados en RMoon** para que nos ayude a entender un poco mejor este fenómeno que tendrá su momento álgido este año en **España el día 12 de Agosto** con el eclipse total de Sol que se verá en varias zonas de la península ibérica en todo su esplendor al atardecer. Se explicará cómo se **puede estudiar un movimiento tan sumamente complejo** como es el de la Luna y como a partir de las predicciones que se nos puede ofrecer en distintas bases de datos, se consigue ubicar, con un alto grado de exactitud nuestro satélite en el cielo haciendo uso de mínimos conceptos matemáticos que nos permitirán entender por un lado la complejidad, pero por otro la mecánica del movimiento lunar.

While some are still meeting online, this is an in person event. Please note that we have attendees of all levels of speaking, including some native speakers. All are welcome! Also, as we meet at the same time and place each week, many don’t RSVP on the app, so we will likely have more attendees than noted here. Note: if you are asked to pay and upgrade the Meetup app, this is not necessary. You can ignore this and still attend our meetings. Find us on our [Facebook group](https://www.facebook.com/share/g/1EKw86WJCp/?mibextid=wwXIfr).

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
