**After a long winter hibernation, we're baaack!** Let's start off the kayaking season on the Rio Zêzere, departing from a meeting point just south of the Castelo do Bode dam.

Whether you're an experienced kayaker or a sporty beginner looking to try something new, this event is perfect for outdoor enthusiasts. **Duration**: approx. 4-5 hours in total * 2.5 hours on the water (incl. breaks) * 2 hours for a picnic lunch and swim at the river beach **Price**: €20 per person. This includes: * Kayak rental, including life jacket and paddle * Certified monitors to ensure the safety of all participants To reserve your spot and facilitate organization with the kayak company, please send your **payment** via Revolut (@maaadison) or MBWay (+491624520214) **by the end of the day Thursday, May 28th**. First come, first served! **What to bring:** * Swimsuit, neoprene, and/or clothes that can get wet * Shoes/sandals that can get wet * Sunscreen and hat * Change of clothes, second pair of shoes, and a towel * Waterproof case for your phone to take pictures along the way * Picnic lunch and blanket **Level:** Suitable for beginners and children (8+).

**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.

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.

**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

Communication is everything in life You are only as successful as your ability to communicate. \- What if you could confidently talk to anyone? \- What if you had the ability to calmly control every conversation? \- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence? You can! The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate.
