What is identity? What is it that holds us captive and causes us to make involuntary decisions? Or perhaps we know why we make them but refuse to take responsibility for them? This is NOT a movie; this is a different kind of experience. We’ll explore identity and watch a film as part of that. All we need is for you to be there.

New Meetup is here! Let's gooo! We have some amazing speakers, and pizza and beer will be available after the event. ────────── **18:00: Welcome** Grab a beer, a snack, and a seat until everybody arrives! **18:30 Intro by Host Neciu Dan** **18:45 The Package Was Fine Yesterday: Why Your Dependencies Are a Security Risk - and What to Do About It** Speaker: [Vitaly Baev](https://www.linkedin.com/in/vitaly-baev/), Senior Frontend Engineer @ Revolut Every JS project relies heavily on third-party code. Some of it runs during install, some in CI, some inside the editor, and some with access to real credentials. This talk explains how recent supply-chain attacks abused that trust and what developers can do to reduce risk without stopping delivery. **19:20 Under the hood: How V8 powers your JS apps (and why you should care)** Speaker: [Gwyneth Rose](https://www.linkedin.com/in/gwyneth-rose/), Senior Engineer at Lodgify You've transpiled your JavaScript, minified it, chunked it, and sent it to your CDN. But what happens when the code actually hits the browser? In this talk, we'll walk through the workings of V8, the JavaScript engine that powers Chromium-based browsers and Node.js. We'll focus on its JIT (just-in-time) compiler, how it learns about your code at runtime, and how it optimizes for performance as you use a web app. We'll also go over concrete techniques to make the JIT compiler's job easier, helping you stay in V8's fastest execution path. **19:50: Drinks and networking!** **20:45 Meetup finished** Would you like to talk at the next meetup?

Join us for our first [Kyverno](https://kyverno.io/)-dedicated meetup before the summer break 🌴 We want to thank **[Schwarz Digits Spain](https://www.linkedin.com/company/schwarz-digits-spain/)** for kindly hosting us for this evening of learning and networking! **🧭** **What is Kyverno?** **[Kyverno](https://kyverno.io/)** is a CNCF-graduated, Kubernetes-native policy engine. Unlike other tools that require learning a new programming language, Kyverno allows you to manage cluster governance, security, and compliance using familiar Kubernetes manifests. With zero coding required, you can easily: * **Validate**: Block non-compliant resources before they hit your cluster. * **Mutate**: Automatically inject sidecars, labels, or configurations on the fly. * **Generate**: Automatically create new resources (such as NetworkPolicies or ConfigMaps) when a new namespace is provisioned. **📅 Agenda** * **18:30-18:45**. Doors Open. * **18:45-19:45**. Talks (see below). * **19:45-20:30**. Mingling and food. **📍Location:** c/ Bergara 13\, Barcelona \| [https://maps.app.goo.gl/zd6h3BGzHNxgAgjT6](https://maps.app.goo.gl/zd6h3BGzHNxgAgjT6) **🎙️ Talks** **1️⃣ The Kyverno Five: New Policy Types And What You Can Do With Them**, [Cortney Nickerson](https://www.linkedin.com/in/cortney-nickerson-26836413a/) *\- Head of Community at [Nirmata](https://nirmata.com)* (Talk in English 🇬🇧) As Kubernetes has evolved, so has Kyverno! This talk provides a tour of the five new Kyverno policy types, ValidatingPolicy, ImageValidatingPolicy, MutatingPolicy, GeneratingPolicy, DeletingPolicy, with real-world examples of how you can use them to solve complex security, automation, and governance issues. The talk will end by showcasing how you can combine the usage of these policy types, for advanced platform engineering solutions. **2️⃣ Kyverno más allá de la validación: automatización con mutación y generación de recursos**, [Javier Dompablo](https://www.linkedin.com/in/javier-d-62a7b824b) - *Expert Platform Engineer and Product Security en [Schwarz Digits](https://www.linkedin.com/company/schwarz-digits-spain/)* (Talk in Spanish 🇪🇸) En esta sesión exploraremos dos de las capacidades más potentes de Kyverno: la mutación y la generación de recursos. Veremos cómo automatizar las configuraciones, aplicar de forma transparente los estándares de la plataforma a los equipos de desarrollo y reducir la carga operativa mediante la creación y la modificación automáticas de recursos en Kubernetes. A través de ejemplos prácticos, descubriremos cómo implementar políticas que mejoran la consistencia, la seguridad y la gobernanza de los clústeres sin necesidad de modificar las aplicaciones. See you there 👋

**¿Te imaginas recibir masaje tailandés al aire libre, respirando naturaleza y dándote un espacio de calma profunda?** Ana te invita a una experiencia de **masaje tailandés en els Jardins de la Maternitat**, pensada para relajar el cuerpo, aquietar la mente y reconectar contigo a través del contacto consciente y el movimiento suave.

**🔎The session:** AI is already part of how we work, but most people are still using it as a chat or an autocomplete tool. The next step is moving from asking for help to letting AI actually do parts of the work for you. **That is where agents come in**. In this session, we explore **how to build and use AI agents in a practical way using tools like GitHub Copilot, Agent Mode, MCP, and reusable skills**. The focus is not on complex architectures, but on what is useful in real day-to-day work. We walk you through **what an AI agent is** and why it makes sense to use one instead of just prompts or simple automations. You will see how agents can reason, plan, and execute tasks across multiple steps, and how to apply patterns that already work in production. We also look at **how this fits into your existing workflow**, especially in environments like VS Code, and **how agents can connect to real systems and data**. Real examples will show how to automate documentation, interact with data platforms such as Microsoft Fabric, and create reusable workflows that save time. The session also **covers common mistakes**, including overcomplicating solutions with too many agents, and how to keep things simple, controlled, and maintainable. 🎯**The goal is to give you a clear and practical understanding so you can start using agents in your own work without overengineering.** 👩‍💻**This session is for you if:** * you are a developer working with code on a daily basis * you use tools like VS Code, GitHub, or similar environments * you are an engineer interested in improving productivity using AI beyond autocomplete * you want to explore how to integrate AI agents into real workflows -No prior experience with AI agents is required -Basic understanding of development workflows is enough 📋**Agenda** 🙋18:00 Registration & Welcome **🗣️18:30** Session and Q&A 🌮19:30 Drinks & Bites We look forward to this inspiring evening together! 🤩

**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Talk by ## [Kyle Jenkins](https://www.linkedin.com/in/kyle-jenkins/) **Unpacking Process Anti-Patterns: Lessons from Ideation to Delivery** In the fast-paced world of software engineering, processes often shape success or sow frustration. Over the years, recurring anti-patterns have emerged well-meaning practices that unintentionally create inefficiencies, stifle innovation, or harm team dynamics. These pitfalls, though rooted in good intentions, can derail projects and undermine trust when left unchecked. Through real-world examples and two decades of industry experience, this presentation unpacks common process anti-patterns across the software lifecycle. With a focus on fostering understanding, not blame, we’ll examine how flawed workflows contribute to challenges and how reversing them can empower teams to build clarity, creativity, collaboration, and trust. **AGENDA:** * See updates to parking below * Doors open at 5:30, feel free to come and hang out before! * Official start of the meeting is at 6:30pm * After the meeting is done, we will go hang out at a nearby space in Bridge Park!
