Hack The Box Meetup Cáceres #10: Hacking a pasarela de pagos
‼️ **EVENTO 100% PRESENCIAL. NO HÍBRIDO.** La plataforma no nos permite cambiar la modalidad.
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?**
* Un portátil
* Burpsuite (con la versión gratuita te vale)
‼️ No es necesario saber utilizar la herramienta de Burpsuite. Sin embargo aprovecharás mucho más la clase si tienes nociones básicas. Recomendamos verte este pequeño tutorial de 10 min antes del meetup: https://youtu.be/DqNMVAUUa-E?si=Hmui_9qdYaTQEnq_

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.
Escalando soluciones de observabilidad con el ecosistema de VictoriaMetrics
**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!

Contra dance with Big Scioty on March 7 - First Congregational Church
**Caller: Frank Buschelmann**
**Band: The Rosenthorns**
**Big Scioty Contra Dance**
**temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215**
WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing!
Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor.
Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner.
Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot.
For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/)
Please bring your own refillable water bottle. Snacks to share are always welcome!
Quarterly Community Gathering
Join the Columbus AI community for our quarterly gathering — a casual, community-focused evening where everyone has a chance to share, learn, and connect. These open mic–style events give anyone in the community up to **5 minutes** to present a project, share a tool, pose a question, or offer a perspective on the evolving AI space.
No slides required — just a welcoming space to exchange ideas and keep the local AI conversation moving.
If you’d like to take the stage, message **Chris (the organizer)** with a **title and short description** of what you’d like to share.
Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

Spec-Driven Development with GitHub Spec-Kit - Barret Blake
**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**
*Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation*
Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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.
