Empty Nesters

**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.

Come join us for a chillax evening nibbling on tapas and sipping wine. We will be heading to one of our favorite hangouts, G Wine in San Pedro. Once again, David is offering us a special promotion of a free glass of wine ( white, red or rose, or beer or soft drink ) with every tapa. They will bill us individually as long as we are not a huge group. Let's see. There will be a Fluffy Tax of €2 per person, and you are expected to pay for your own food and drinks as and when you order. Please remember to get a receipt for your payment, so we don't have a repeat of the problem we had in a previous event held at Yanx. Please make sure you turn on notifications and respond to my messages promptly. Otherwise, I will assume you have signed up by mistake and won't actually be coming. Hasta luego amigos.

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
