*** **Resumen:** Integrar modelos de aprendizaje profundo de Keras en el ecosistema Tidymodels ha sido tradicionalmente como mezclar agua y aceite: Keras es imperativo y basado en grafos, mientras que Tidymodels es declarativo y espera argumentos de configuración fijos. Esta charla presenta kerasnip, un paquete de R que une ambos mundos tratando la topología de la red neuronal como un hiperparámetro más. Se demuestra cómo usar "Bloques de Modelo" y especificaciones dinámicas para ajustar estructura del modelo, como la profundidad, el ancho y las ramificaciones de la red, utilizando herramientas estándar como tune_grid(). Aprenderá a definir planos de modelos flexibles que exponen su estructura como "diales" ajustables, llevando la capacidade de crear modelos complejos de Keras a Tidymodels.

Sala Resistencia. Aforo máximo 30. **Dirección**: P.º de La Habana, 9, 11, Chamartín, 28036 Madrid **Metro**: Nuevos Ministerios **!!!Comenzamos estrictamente a las 18:30h!!!** **Charla** **Título:** Escalando soluciones de observabilidad con el ecosistema de VictoriaMetrics. **Ponente:** [Jose Gómez-Sellés](https://www.linkedin.com/in/joseluisgomezselles/) **Puesto**: Product Lead - VictoriaMetrics Cloud **Mini-biografía:** Product Manager práctico, con gran interés en la investigación, enfocado en mejorar la eficiencia tanto del software como de los procesos. He construido mi carrera sobre desarrollo de software, ingeniería de sistemas y arquitectura de software en la industria de las telecomunicaciones. Posteriormente, me uní a Red Hat como PM para proyectos de observabilidad como OpenTelemetry, trazado distribuido, Jaeger, Tempo y Kepler. Mi objetivo es generar un impacto real construyendo comunidad a través del intercambio de conocimiento: enseñando a quienes se inician, participando en actividades de mentoría, entrevistando candidatos y diseñando programas de aprendizaje. **Descripción de la charla:** Cuando se trata de escalar soluciones de monitorización de series temporales, las cosas pueden volverse un caos. Esa es una de las razones por las que VictoriaMetrics, miembro Silver de la Cloud Native Computing Foundation (CNCF), comenzó su recorrido hace algunos años. Es un conjunto de soluciones de observabilidad simple, fiable y eficiente, adoptado por muchas organizaciones. Es de código abierto, con una comunidad sólida detrás, y ofrece opciones enterprise y gestionadas (Cloud) para quienes necesitan soporte. VictoriaMetrics se integra muy bien con muchos estándares, incluyendo Grafana y OpenTelemetry. Además, por si no lo sabías, VictoriaLogs es el nuevo jugador del mercado y está superando seriamente a otras soluciones. En esta presentación, mostraremos los proyectos Open Source de VictoriaMetrics y en qué se diferencian de otras soluciones, especialmente cuando se trata de escalar desde instalaciones pequeñas y sencillas hasta despliegues masivos en clúster. ¡Ven a descubrir cómo los proyectos de VictoriaMetrics pueden hacer la observabilidad mucho más fácil! *** Si aún no te has unido a la comunidad de Discord, ¡por favor, hazlo!

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.

Join us for this free, in person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Do you want more motivation and confidence to build lasting relationships? Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is held at the Dianetics and Scientology Life Improvement Center of Central Ohio.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
