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.

**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)

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.

**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!
