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**.

***Las matemáticas como ciencia y símbolo: un viaje al lenguaje oculto que ordenaba el cosmos en la antigüedad.*** Desde civilizaciones antiguas, las matemáticas fueron mucho más que una herramienta de cálculo, llegaron a constituir un lenguaje sagrado capaz de expresar el orden invisible del cosmos y la armonía que subyace a todas las cosas. Números, proporciones y formas geométricas eran entendidos como Principios, símbolos vivos que articulaban la relación entre el ser humano, la naturaleza y lo divino. Esta charla explorará cómo el Número constituyó una auténtica Ciencia que daba sentido a las plasmaciones humanas. Charla impartida por: Óscar Acevedo 🎟️ Actividad gratuita ⚠️ Sé responsable con tu inscripción. Si no puedes asistir, por favor, cancela tu plaza para dar lugar a otra persona.

**Maybe you used to draw but fell out of the habit?** **Maybe you’ve always wanted to start, but find it hard to stay motivated?** **Or maybe you're just looking for a friendly space to sketch and meet new people?** **Come draw with us! :)** We host free, casual drawing meetups. There are no rules, no pressure — **just bring your own materials**, draw whatever you feel like, and enjoy the company of fellow creatives. Every session, we propose a theme to spark your inspiration.

Si tu pasión es el collage, quieres conocer personas que con las mismas inquietudes o simplemente quieres relajarte cortando y pegando con un buen vino, este evento es para tí. Un evento collagero donde tendrás un sitio de reunión, experimentar, conocer personas y conectar mientras hacemos collage con un buen vino. ¿Quién sabe que puede salir de estos encuentros? La Clandestina aportará los materiales como revistas, papel y pegamento. Pero si quieres buscar en el baúl de los recuerdos de revistas o libros raros para experimentar puedes traerlo, así como fotos y otros. El taller es para todos los niveles ya que venimos a experimentar y entre todos nos ayudaremos.

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.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)

Dear ACM Chicago Chapter members, On March 4, we are hosting a hybrid event at AON Center (200 E. Randolph, suite 200). Please note that this venue requires the attendee list to be submitted 48 hours before the event starts, so the RSVP will close then. Please remember to bring your government-issued ID to present to building security. You can also join virtually using the Zoom link below: [https://acm-org.zoom.us/webinar/register/WN_Ky5PEBMTSaiGQ6Q42-qrNA](https://acm-org.zoom.us/webinar/register/WN_Ky5PEBMTSaiGQ6Q42-qrNA) **Talk Title:** Effective Data Visualization **Speaker:** David Giard, Partner Solution Architect at Microsoft, **Tald Abstract:** We spend much of our time collecting and analyzing data. That data is only useful if it can be displayed in a meaningful, understandable way. Yale professor Edward Tufte presented many ideas on how to effectively present data to an audience or end user. In this session, I will explain some of Tufte's most important guidelines about data visualization and how you can apply those guidelines to your own data. You will learn what to include, what to remove, and what to avoid in your charts, graphs, maps and other images that represent data. **Agenda (Central Time):** * 5:30 – 6:00 PM — Networking * 6:00 – 6:05 PM — Introductions * 6:05 – 6:45 PM — Talk * 6:45 – 6:55 PM — Q&A * 6:55 – 7:00 PM — Adjournment * 7:00 – 7:30 PM — Networking Refreshments will be provided. Hope to see you there!
