**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.

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. 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

Welcome, readers! Our May read is **_Kindred_ by Octavia E. Butler.** The story follows Dana, a Black woman living in 1976 California, who is suddenly pulled back to a Maryland plantation before the Civil War. She learns her survival is tied to a white slaveholder’s son. Forced to move between centuries, she must endure the brutal realities of slavery while fighting to hold on to her identity. Tense, intimate, and unforgettable, Kindred explores how the past refuses to stay buried. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **drinks must be purchased at the bar.** Happy reading! 📖

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.
