_______________ **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.

**DevSecCon España / AI Sec Eng** en colaboración con **Madrid DevOps** y **HackerDreams %27** **📅26 de febrero, 2026** **🕖6pm CEST** **Agenda:** **Lugar**: Utopicus Paseo de La Habana. 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!

A classic Italian road comedy that was so good the film ministry recognized it as "culturally significant." Starring Vittorio Gassman and Jean-Louis Trintignant, the film shows that for young men in love the rules of the road are only suggestions. And the rules for love? Hey, this is an Italian picture! Oh to be young and filled with joie de vivre or la dolce vita. A french/italian fun filled movie with a surprising twist at the end. Do you have a fun memory from your youth? Location TBD, but it will be in person for sure!

Join us for something different as we get together to see EPIC: ELVIS PRESLEY IN CONCERT! While researching his 2022 film, director Bas Luhrmann came across and compiled rare and previously unseen interviews and videos of Elvis in concert to create “one of the most exciting concert films you’ve ever seen!” Here are details, a trailer and our plan for this event: DESCRIPTION: Part documentary, part concert film, the latest from director Bas Luhrmann is a follow-up to his 2022 film starring Austin Butler. While researching the film, he came across 68 boxes of previously unseen interviews, concert performances and outtakes from previous films. A combination of offstage and onstage Elvis, comes a film that “befits the magnitude of Elvis as a performer but also offers deeper revelations of his humanity and inner life." It is written/directed by Baz Luhrmann (ELVIS, MOULIN ROUGE, THE GREAT GATSBY) and stars the legendary Elvis Presley! TRAILER: https://www.youtube.com/watch?v=NmqWusmzp0k BUZZ AND ACCLAIM: The film screened at the 2025 Toronto Film Festival where it was the runner up in the category People’s Choice Award for Documentaries. Next Best Picture says, “Certain to energize longtime fans and generate new ones for generations to come, EPiC: Elvis Presley in Concert is a masterwork of montage.” And according to the NY Post, whether you have a room in the house devoted to Elvis or not, this truly “Epic” concert film is an energizing experience!” PLAN: We’ll plan for a pre-show bite at nearby BRAVO around 5 or 5:30pm followed by a 7pm-ish showing on one of their larger screens. Once showtime is announced, advance ticket purchase is advised. Please list your seat number in the Comments below. Exact showtime and meeting details will be confirmed/announced as the date gets closer. Look forward to seeing you there, Dan
