**What it takes to work as a Product Trio in an AI-first world?** Product Tank Barcelona is back — and this time we're bringing the full squad. This June, we're co-hosting ProductTank Barcelona at **G2's brand new Barcelona office** for a conversation that's long overdue: what does cross-functional collaboration actually look like when AI changes everything about how we build? **Three voices. One stage.** We'll hear from a PM, an Engineer, and a Designer — each sharing their perspective on what it takes to work as a product trio in an AI-first world. No silos. No hand-offs. Just honest lessons from teams doing it in practice. Together, they'll explore: * What the "Single Stack Builder" model means in practice * Why shipping a feature is no longer the goal — driving outcomes is the only measure of success * How PMs, designers, and engineers prototype together, teach each other, and actually move the needle on OKRs 🎤 **Meet the Speakers** **Karine K.

In this talk, I share how I built a personal AI system that sees the same inputs I do: Slack channels, meeting transcripts, Notion docs, people profiles. The system learns my patterns over time and surfaces insights before action — not after. Through six concrete principles and real examples, I show what it means to architect context instead of carrying it in your head. And what stays irreversibly human: presence in 1:1s, lead-by-example moments, empathy in hard conversations. 19:00 - **Don't Delegate Understanding,** Pau Ramon, CEO at Ramensoft. Is this an AI talk or a Leadership talk? There's only one way to know. 19:25 – Closing remarks 19:30 – Networking with Food & Drinks 21:00 – Close Spaces are limited – **RSVP to secure your spot** and join a community of engineering leaders who are shaping the future of tech!

This is the third in a series of meetups exploring the exciting world of **[OpenTelemetry](https://opentelemetry.io/)** within the cloud-native ecosystem. And this time, we are partnering with our good friends at [Write the Docs Barcelona](https://www.meetup.com/write-the-docs-barcelona/). Whether you're just curious about observability or already a seasoned OpenTelemetry user, this series will offer valuable insights, practical knowledge, and opportunities to connect with fellow enthusiasts in the Barcelona cloud-native community. **📍 Location:** **[Factorial](https://factorial.es)** \- Carrer de Llacuna 56\, building C\, Barcelona \| [https://maps.app.goo.gl/baTqk9H8m3ACK4jD7](https://maps.app.goo.gl/baTqk9H8m3ACK4jD7) **👉 Here's a sneak peek of the agenda:** **18:30:** Check-in and welcome 👋 **18:45:** 🎙️ **"Collaborating in OSS projects: The OpenTelemetry Docs case study"** by **[Anna Urbiztondo](https://www.linkedin.com/in/annaurbiztondo/)** - *Senior Technical Writer at [Grafana Labs](https://grafana.com)*, **[Fabrizio Ferri-Benedetti](https://www.linkedin.com/in/fabrizioferri/)**[ ](https://www.linkedin.com/in/fabrizioferri/)- *Principal Technical Writer* *at [Elastic](https://elastic.co)***.** This Write the Docs meets Cloud Native talk covers what makes open-source projects succeed in practice — clear focus, community ownership, organization, goodwill, and excellent communication in a fast-moving codebase.

We’re thrilled to announce the next edition of the BcnRust Meetup, this time hosted by **[Protofy](https://protofy.xyz/)**! Join us for an evening exploring two very different but equally ambitious Rust projects: an AI-native virtual machine that rethinks how code is executed, and a distributed task queue built as a hands-on journey into async Rust, concurrency, and fault-tolerant systems. Whether you're interested in language runtimes, AI agents, distributed systems, or simply seeing how Rust enables bold ideas, this meetup is for you. **Driver: An Agentic VM in Rust** by [Cristian Sánchez](https://www.linkedin.com/in/cr3at0r/) Most virtual machines are deterministic by design. LLMs break that. But what if AI wasn't an external API on top, but a native execution primitive inside the VM itself? Driver is a Rust VM where AI is a first-class execution primitive. The stdlib is aware of whether it's being invoked by deterministic bytecode or by an LLM-generated action and behaves accordingly. We'll cover the practical decisions behind the core VM, and the toolkit around it. **Aether: Learning Async Rust by building a Distributed Task Queue** by [Arnau Berenguer](https://www.linkedin.com/in/arnau-berenguer-jimenez/) Building a distributed system is a great way to learn async Rust because you run into all the hard parts for real. In this talk I'll walk through Aether, a personal project of a task queue that lets you submit and run Python scripts on a cluster from a CLI. We'll cover the system architecture, how to handle multiple concurrent tasks sharing state, how to handle loss of connection, and propagating cancellation signals on concurrent tasks over the network. Along the way we'll see the honest lessons learned and what makes async Rust hard but fun. **Why Attend?** * Explore advanced Rust applications, from AI-native runtimes to distributed infrastructure. * Learn practical lessons about virtual machine design, async programming, concurrency, and fault tolerance. * Discover how experienced Rust developers approach complex systems and architectural trade-offs. * Connect with Barcelona's Rust community and exchange ideas with fellow engineers, makers, and enthusiasts. * Get inspired by real-world projects that push Rust beyond the usual web services and CLI tools. Whether you're a Rust beginner curious about what's possible, or a seasoned developer looking to dive deeper into systems programming, you'll leave with new ideas, technical insights, and plenty to discuss. Let’s build, learn, and geek out over Rust together! 🦀 **Streaming**: We will stream it via YouTube so you can also subscribe to our [YouTube channel](https://www.youtube.com/@bcnrust) to get notified when we go live.

The event is free. Join us for at the meetup at Barcelona Bar, designed for women passionate about technology. This is more than just a meetup; it’s an opportunity to connect, share experiences, and build relationships that can propel your career forward. **Why Attend?** * **Meaningful Connections:** Meet other women who, like you, are working to transform the tech industry. Whether you’re a software engineer or a startup leader, this is the perfect space to expand your professional network. * **Mutual Inspiration:** Hear and share stories of success, challenges overcome, and lessons learned. Together, we can gain new perspectives and motivate each other to continue growing. * **Relaxed Atmosphere:** Enjoy an evening in the cozy setting of BrewDog, where conversations flow as easily as the craft beer. It's the perfect environment to unwind and engage with like-minded women in tech. Don’t miss this chance to connect, inspire, and be inspired. Let’s build a stronger tech community together!

We'll provide signage for your game to help others learn more about your work. Wifi, outlets, tables, and seats (though standing tables also) are available. Come to the Prototype and Play workshop to collaborate and meet local game developers for an evening of epic and raw game play fun! Play works-in-progress, show off your own game, work with others to add polish to a game, or even lend your talents to other fellow developers. For this event, light snacks from the bar and water will be provided! Though you can purchase you own if you like at the bar: [https://www.game-arena.co/menu](https://www.game-arena.co/menu) Can use South Garage at the Gateway with a $5 voucher on your way out. 75 E 11th Ave, Columbus, OH 43201 [https://maps.app.goo.gl/UwgveUYG37Jy7RtS9](https://maps.app.goo.gl/UwgveUYG37Jy7RtS9) If you have any questions or comments, as always, feel free to reach out to us at [info@thecogg.com!](http://info@thecogg.com!/)

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier! Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is brought to you by the Dianetics and Scientology life improvement center.

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!
