Este taller está orientado a **todo tipo de participantes**, con o sin conocimientos previos en ciberseguridad. Sí pedimos unas nociones básicas de informática.
** ¿Qué aprenderás?**
3 Técnicas. 3 Maneras diferentes de hackear un pago online. 3 Fallos que los desarrolladores cometen al implementar sistemas de pagos. ¿4? No. Solo 3.
**** **¿A quién va dirigido?**
A toda persona que le interese saber cómo atacar (o por lo tanto proteger) pagos online.
** ¿A quién no va dirigido?**
Irresponsables, gamberros, inmaduros… Cualquier persona que crea que el poder saltarse la seguridad de un pago online le da derecho a hacerlo.
** ¿Qué necesitas para participar?**

101 - Reunión Grupo de R: Jueves 26 de febrero de 2025
***
**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.

**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!

Oscar International Nominee: SIRAT at the Gateway Film Center
Join us as we get together to see SIRAT, an Oscar-nominated Best International Film from Spain that follows a father, accompanied by his son, goes looking for his missing daughter in North Africa. Here’s a description, trailer and our plan for this event:
DESCRIPTION: A father, accompanied by his son arrive at a rave deep in the mountains of southern Morocco while searching for his daughter who vanished months ago at one of these endless, sleepless parties. As their search continues, the journey forces them to confront their own limits. The film is directed by Oliver Laxe and stars Sergi Lopez, Bruno Nunez Arjona and Richard Bellamy.
TRAILER: https://www.youtube.com/watch?v=ww-IXHXvS70
BUZZ & ACCLAIM: SIRAT has already won numerous awards, including 4 at the 2025 Cannes Film Festival, along with the Chicago, Montclair and Toronto International Film Festivals! It also earned a whopping 11 nominations at the 40th Goya Awards, including Best Film and Director, and was nominated for Best International Feature Film and Best Sound at this year’s Academy Awards. The film is earning a stellar 92% positive rating on Rotten Tomatoes which calls it “an unforgettable exercise in tension” and “a brutal reminder that the journey can be more important than the destination.”
PLAN: We’ll plan for a 7pm-ish showing and will confirm/announce details as the date gets closer. Once showtime is confirmed, advance purchase (via GFC website preferred) is advised! Once you have your ticket, please list your seat number in the Comments section of this event.
PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night!
Look forward to seeing you there, Dan
