We’re thrilled to announce a special edition of BcnRust taking place inside the **Talent Arena at Mobile World Congress 2026**, thanks to the collaboration between the **[Rust Foundation](https://rustfoundation.org)** and **[Mobile World Capital Barcelona](https://mobileworldcapital.com/)**. This unique event brings together hands‑on workshops, a community meetup, and exclusive access for Rust developers across Spain — including our friends from **[MadRust](https://www.meetup.com/es-es/madrust/)**, represented by our meetup speaker **[Jorge Ortiz](https://www.linkedin.com/in/jorgeortiz/)**. **📅 Schedule — Wednesday, March 4th** **Workshop 1 — General Access** 9:30h – 10:45h **When Floats Lie:** *Performance, and why Rust keeps AI from corroding* **Speaker:** [Lawrence Freeman](https://www.linkedin.com/in/thedatachef/) "Floating-point numbers are prone to subtle failure modes that erode performance and correctness. We will build a small quantization framework in Rust, evolving step by step as we move from numeric fundamentals to Post-Training Quantization (PTQ) for AI inference. You’ll learn how quantization works at the bit level, and why Rust is becoming critical infrastructure for high-performance, resource-constrained, AI-driven systems." This session is free to attend. Simply register at: 👉 [https://talentarena.tech](https://talentarena.tech) **Community Meetup — XPRO Access** 13:30h – 14:30h (extended until 14:50 if needed) **Make Rusty AI** *Building an agent from scratch using Rust and open‑source tools* **Speaker:** [Jorge Ortiz](https://www.linkedin.com/in/jorgeortiz/) (MadRust) "Artificial intelligence has infiltrated nearly every aspect of our lives. Assistants are now capable of performing tasks that were once science fiction, and we’ve started integrating them into our daily routines. But do you fully understand the concepts at play? Can you distinguish between a chatbot and an agent? Could you write your own AI tools? In this talk, we’ll build an agent from scratch using Rust and open-source tools. While the session will involve live-coding, the focus will be on understanding the core concepts and applications of artificial intelligence. It’s an opportunity to explore how emerging technologies are reshaping the way we interact with computing—and how you can contribute to this revolution." Join us for a deep dive into practical Rust‑powered AI, followed by community discussion and networking with Rustaceans from Barcelona, Madrid, and beyond. **Workshop 2 — XPRO Access** 16:45h – 18:00h **From fRusTrait‑ion to Async Mastery**: *Become a Rust Trait Hero in 90 minutes* **Speaker:** [Lawrence Freeman](https://www.linkedin.com/in/thedatachef/) **🎟️ About the XPRO Passes** Thanks to the Rust Foundation, we have **150 XPRO passes** available for the community. These passes grant access to the **meetup** and the **second workshop**, as well as the full Talent Arena program. We will distribute the codes **in order of request via Meetup**.

Soltar no es perder, ni resignarse; es crear espacio para lo nuevo sin vivirlo desde el dolor.** En este evento exploraremos el verdadero significado de soltar desde una perspectiva espiritual y emocional, alejándonos del sacrificio y el suyfrimiento, y acercándonos a la conciencia, la aceptación y la paz interior. Durante la sesión abordaremos: * *Por qué nos aferramos a personas, situaciones y emociones que nos dañan* * *La diferencia entre soltar desde la mente y soltar desde la conciencia* * *Cómo liberar culpa, resentimiento y expectativas sin lucha interna* * *El vacío como espacio de transformación, no como carencia* Este encuentro está dirigido a personas que sienten que algo les pesa emocionalmente, que repiten patrones del pasado o que desean avanzar con mayor ligereza, claridad y conexión interior. No se trata de forzar el cambio, sino de permitirlo. Vaciar no es quedarse sin nada; es prepararse para recibir lo que está alineado contigo. ***Si estás en un momento de cierre, transición o transformación personal, este evento puede marcar un antes y un después.*** Ponente: Iván Aznar Colaboración: 5 euros (costes de sala y organización).

La identificación con alguien, con unas características, con una situación, con unas circunstancias, con una edad..., hace sufrir y nos cierra. No podemos decir que soy mi profesión, o que soy esto o lo otro. No puedes ya que cambias y además ¿cual es tu esencia? Tu esencia no tiene forma y es un espacio abierto en que no eres así o asá. Si entras en ti, en tu ser real, no puedes identificarte con nada, solo sentir paz y amor. Tu ser esencial no es inseguro, o muy sensible, o inteligente, o tonto. Y no puede ser maltratado, ni siquiera es lo que te dices. Ninguna categoría habla de ti. Al decirnos que somos lo que sea, lo alimentamos y aumenta, nos enganchamos a la forma, tenemos que defender ideas, opiniones, y nos esclavizamos a eso. El resultado es que tú disminuyes. Nuestra esencia es libre, pacífica y feliz. Si al **SOL que** **eres** le despejas las nubes, lo que crees que te define, lo que te condiciona, queda el sol. Pero siempre estamos buscando como si tuviéramos que encontrar o encontrarnos. Pero ¿y si estuviéramos presentes?... ¿Qué es estar presentes? Veámoslo, porque estás más cerca de la meta y del bienestar de lo que crees. La meta eres tú. Tú **ya** **llegaste** pero *no* *lo* *sabes*, eres el sol. Miguel Pou es premio Príncipe de Asturias y mediante reflexiones inspiradoras, experiencias transformadoras y *dinámicas* *participativas* te ayuda a abrazar tu vida, tú situación y a tí saltando barreras y desarrollando tu presencia auténtica en tu día a día. Después del Éxito de la conferencia "Me elijo a mí..." ven a un nuevo evento para entender los beneficios de soltar máscaras y para ser tú mismo. **Sobre Miguel Pou:** Es investigador y escritor con varios premios científicos, es formador de escritores y tiene 4 libros publicados.

**[Únete a nuestro grupo de whatsapp](https://chat.whatsapp.com/Cp2jyUS8Z9a0AsWJ1kbV0f)** ¿Y si lo más importante no estuviera frente a ti… sino justo donde decidiste no mirar? Vivimos rodeados de estímulos que compiten por segundos de atención. Luces, pantallas, titulares, promesas brillantes. Pero mientras algo capta tu mirada… algo más ocurre fuera de cuadro. *Desatención* no es solo una muestra visual: es un recorrido donde lo evidente distrae y lo sutil susurra. Donde cada imagen parece decir una cosa… mientras insinúa otra. Aquí nada es casual. Ni siquiera aquello que parece irrelevante. **aportación :** 5€ para gastos de organización. **Dirección:** Amaltea (calle Diputación 164) Te esperamos! :)

Este evento está diseñado para quienes desean **dejar de luchar contra sí mismos**, identificar los obstáculos internos que impiden la paz y aprender herramientas prácticas para recuperarla. Exploraremos cómo **liberarnos de lo que nos bloquea**, reconstruir calma interior y abrir espacio para bienestar y serenidad duradera. Porque la paz **no es algo que logras**… es algo que dejas de impedir. **aportación:** 5€ para gastos de organización. Te esperamos! :)

Drake Lundstrom is presenting: Code Anywhere by Talking to your Phone Abstract: Have you heard the trend of people deploying code anywhere from checkout lines to doctors' offices? In this talk, you will learn how to talk to your phone and have an app on Azure to show your friend 5 minutes later. The basic DevOps tools you already know, plus a little bit of AI magic, are all you need! If you want to follow along, the demo will be in Azure with GitHub Actions and GitHub Copilot, and you can have it set up on your phone by the end of the session. Just come in with an Azure account and a GitHub repo. Join us for pizza, drinks, and networking @ Improving's office. Doors open at 5:45.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Projects that are over budget, delayed, or that fail to scale past the POC phase are very common. In many of these scenarios, choosing the right approach can be as critical as the solution itself. Should you build a tailored machine learning model, leverage the power of large language models (LLMs), or integrate with AI copilots? Each option has unique strengths, trade-offs, and resource requirements, and the key to success lies in aligning your choice with your business goals and technical constraints. In this talk, we will go beyond the basic concepts and definitions to provide a practical guide that allows attendees to navigate these decisions through real-world case studies. We will examine scenarios in which different AI paradigms were chosen, discuss the factors that influenced those decisions, and outline the process for evaluating needs, constraints, and outcomes. From assessing data availability and team expertise to balancing cost and scalability, you'll gain insights into the critical considerations that guide the selection process. By the end of this session, you’ll have a clear process for determining whether machine learning, LLMs, or copilots are best suited to your AI challenges and understand the resources and strategies needed to bring your chosen solution to life. This talk is ideal for decision-makers, technical leads, and innovators seeking to demystify AI implementation and maximize the impact of their investments.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
