Concurrent Programming

For this month's Meetup, we are going back to the Cibernàrium at Barcelona Activa, hand in hand with **Mobile World Capital**. We will have two talks: one about **Feedback for programming learners** and another one about a **Python-powered security lab**. \-\-\- Schedule: * 18:00: Welcome * ️ 18:15: Talks * **&** 20:00: Networking! * 20:45: Bye! \-\-\- * ➡️ **What: Feedback immediat per estudiants de programació: Powered by Python** * **Who**: Moisès Gómez Girón * ⏱ **Duration**: 45 minutes * **Language**: Catalan * **Abstract**: Presentació d’una eina per a l’ensenyament de la programació, creada per minimitzar el temps entre la resolució de l’exercici i la recepció de la retroacció. L’eina ha estat desenvolupada al llarg dels anys en paral·lel al seu ús a l’aula, sota pressió per terminis ajustats, canvis de temari i estudiants amb imaginació per trobar maneres enginyoses d’enganyar el sistema. El resultat és una història de compromisos i solucions creatives, des de prohibir funcionalitats concretes del llenguatge fins a l’ús exclusiu de tecnologies gratuïtes. \-\-\-\- * ➡️ **What: Python-powered Cybersecurity Lab: Caldera, Elastic Stack & ATT&CK simluation** * **Who**: Mauricio Volcanes * ⏱ **Duration**: 45 minutes * **Language**: Spanish * **Abstract**: En esta charla mostraremos un laboratorio completo de ciberseguridad compuesto por máquinas virtuales, Elastic Stack y el framework MITRE Caldera (Python). A través de una demostración guiada, analizaremos cómo simular técnicas del framework MITRE ATT&CK y cómo correlacionarlas en tiempo real con logs de sistemas Linux para detectar comportamiento malicioso. \-\-\-\- ➡️ Location: Cibernàrium 22@ - Barcelona Activa.

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?

## **From Data Autonomy to Adaptive AI: Building Systems That Change How Decisions Get Made** **DOORS OPEN: 18:30** **TALKS START: 19:00** **NETWORKING: 20:00 - 21:30** ## **Our Speakers** **Marta Expósito Ventura, PhD, Head of Data, Stark Future** **Africa Perianez, Co-founder & CEO, Causal Foundry** ## **Marta Esposito - From ticket queues to data autonomy - engineering the shift** **Marta Esposito is Head of Data at Stark Future, an electric motorcycle company building high-performance, connected vehicles at the intersection of hardware, software, manufacturing and data.** **In her talk, Marta will explore what it takes to move a data function away from reactive ticket queues and towards a more autonomous operating model. As connected products generate increasingly rich streams of operational, product and user data, the role of data teams changes: from responding to requests, to enabling better decisions across the organisation.** **Her session will look at the engineering, organisational and cultural shift behind data autonomy: how teams structure data work, prioritise internal demand, build trust in data products and move closer to the real systems they support.** ## **Africa Perianez - Designing AI for imperfect conditions** **Africa Perianez is Co-founder and CEO of Causal Foundry, where she leads a team of engineers and AI scientists building reinforcement learning and personalisation technologies for real-world operational decision-making.** **Her work focuses on adaptive AI infrastructure that supports decisions across healthcare, logistics, behavioural nudging, demand forecasting, stockout prevention and resource allocation. Causal Foundry works with global partners including the Gates Foundation, Google.org, GAVI, Lilly and Johnson & Johnson, applying AI in environments where decisions are complex, resources are constrained and impact matters.** **In this talk, Africa will explore how AI systems move beyond prediction and dashboards into adaptive decision support. What does it take to build systems that can operate across changing contexts, local constraints and human behaviour? And how do you design AI that supports better decisions without pretending the real world is cleaner than it is?** ## **What’s In It For You?** **Some of the most interesting work in AI today is not just about building more powerful models. It is about turning data, machine learning and decision intelligence into systems that people and organisations can actually use.** **In this DeepTech Talks edition, Marta and Africa will explore two complementary sides of applied AI: how data teams become more autonomous inside complex organisations, and how adaptive AI systems support operational decisions in the real world.** **You’ll hear about:** * **How data teams move from reactive service models to autonomous data products** * **What it takes to build AI systems that support operational decision-making** * **How reinforcement learning and personalisation can be applied beyond consumer tech** * **The gap between dashboards, predictions and decisions that actually change outcomes** * **How technical teams work with messy real-world systems, constraints and stakeholders** **Expect a grounded conversation about AI that becomes s part of how organisations sense, decide and act.** ## **Who Should Come?** * **Data scientists, ML engineers and AI engineers** * **Data leaders, analytics leaders and engineering managers** * **Product leaders working with data-heavy or AI-enabled systems** * **Deep tech founders and technical operators** * **People working across healthtech, mobility, logistics, manufacturing or decision intelligence** * **Anyone curious about how applied AI becomes operational infrastructure** ## **Extras** **We’ll have food and drinks. 🍷🍕** **Come ready to meet engineers, founders, esearchers, data leaders and technology builders working on the next generation of applied AI systems.** **Spaces are limited, so grab your spot on Meetup while you can.** **Brought to you by DeepTech Recruitment & Cloudworks.** The organisers and venue reserve the right to refuse admission or entry and shall not be held liable for any incidents, losses or damages occurring during the event.

**Event Summary** 5 minutes. Two woman. A spark. Rotate through 1-on-1 conversations with 15+ women in tech and find your next partner, mentor, co-founder, or collaborator. **Description** Want to meet interesting women in tech without the pressure? This is speed networking — a gentle, human format where you have 1-on-1 conversations with women you'd actually want to know. No pitches. No performing. Just real talks with real people. **How it works:** You sit across from someone. You have 5 minutes to talk. Ask each other what you're building, what you're curious about, what you're working through. A soft bell rings. You move to the next person. By the end of 90 minutes, you've met a dozen women — some become collaborators, some become friends, some just remind you why you love this work. **Who's this for?** Woman in tech, Founders, engineers, designers, product managers, mentors, marketing, etc. anyone building or exploring in tech. Early-stage or scaling. Experienced or just starting. All we ask is genuine curiosity and an open heart. Whether you're looking for a co-founder, a mentor, a peer who gets it, or just interesting people to learn from — there's space for you here. **Why this format?** It feels like a real conversation, not networking. Because it is. Meet quality over quantity. 5 minutes is enough to know if there's real connection. Unexpected friendships. Sometimes the person who changes your trajectory isn't who you were looking for. Share what you know. If you've got experience, there's someone here who'd love to learn from you. If you're early-stage, there's someone who remembers what that felt like. Just women being humans together. No competition. No ego. Just real. **What to bring:** Yourself. Your ideas. Your phone (LinkedIn app open and ready). We'll provide prompts to get conversations started if you need them. After the event you can stay for a non-structured networking to keep going the conversation. We'll add you to a WhatsApp group so you can follow up with the people you connected with. The magic happens in the DMs — so show up ready to be proactive. **WhatsApp Group:** [https://chat.whatsapp.com/GSwiV9YYOtwCcxnOPvgtbL](https://chat.whatsapp.com/GSwiV9YYOtwCcxnOPvgtbL)

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
