**“¿Cómo conseguimos grandes diseñadores? Los grandes diseñadores diseñan, por supuesto.”** *Fred Brooks* **“Entonces, ¿cómo se supone que vamos a conseguir grandes arquitectos si solo tienen la oportunidad de ser arquitectos menos de media docena de veces en su carrera?”** *Ted Neward* ¡Estamos de vuelta con otra [kata focalizada en diseño de sistemas](https://www.architecturalkatas.com/)! 🎉 ¿Qué es una [kata de arquitectura](https://continuous-architecture.org/docs/rituals/architecture-kata.html)? En pocas palabras, los katas de arquitectura son ejercicios diseñados para maximizar el esfuerzo en arquitectura, minimizar los costes innecesarios y completar todos los elementos críticos que un ejercicio de arquitectura debe incluir: un cliente, restricciones del proyecto, requisitos cambiantes, compañer@s y un proceso de revisión. No se requiere experiencia previa en diseño de sistemas o arquitectura. No tener experiencia puede ser incluso más beneficioso: no tendrás ideas preexistentes sobre cómo “debería” hacerse. *El idioma principal será el 🇪🇸 y podemos acomodarnos al 🇬🇧 según asistentes.* **📅 Agenda** * 18:30-18:45. Bienvenida de [eDreams ODIGEO](https://www.edreamsodigeo.com/es/). * 18:45-20:00. Introducción breve a la kata, **cell-based architecture** **y sus diferencias con microservicios**. Después trabajaremos en grupos pequeños, de 3 a 5 personas, sobre un escenario ficticio pero realista que revelaremos durante el evento. Finalmente, pondremos en común las soluciones propuestas. * 20:30-21:00.

**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Ryan Carroll **Local AI in Rails: Fast, Cheap, and Predictable** Rails apps usually reach for external AI services when they need “intelligence,” but that approach can bring latency, cost, and unpredictability along for the ride. This talk shows a different path: running a Japanese sentiment model directly inside a Rails app, using ONNX Runtime, background jobs, and real-time updates to keep the user experience fast and responsive. Using a small app called **Sentiment Omikuji** as the case study, the talk walks through how the model was trained in Python, exported to ONNX, and loaded into Ruby for local inference. It also covers how Japanese text is tokenized, how the sentiment output drives a fortune generator, and why the app uses Solid Queue to keep model work off the request path. Along the way, the talk explores the tradeoffs of local inference versus API-based LLMs, and why classic machine learning can still be the right tool for focused problems. Attendees will leave with a practical architecture they can adapt in their own Rails applications, plus a clearer picture of when local AI makes sense, how to keep it predictable, and what it takes to make it feel good in a real app. **AGENDA:** * See updates to parking below * Doors open at 5:30, feel free to come and hang out before! * Official start of the meeting is at 6:30pm * After the meeting is done, we will go hang out at a nearby space in Bridge Park! If you can, please sign up via meetup by noon the day of the meeting so we can have an estimate headcount for food :) We always order extra, so feel free to join us even if you don't get signed up! Thank you to Bold Penguin for providing the food and location! **Parking & Arrival:** **Parking:** Parking in Bridge Park is free. The closest lots are the Mooney Garage and the Hotel/Endres Garage. **Entry:** The doors to the office are to the right of PINS. The street level door and elevators lock at 6pm. If you arrive after that, someone should be there to let you in, else call the number posted. Take the elevator to the 2nd floor. Once you exit the elevator, turn right. \*\*\* We are a bunch of professionals, students, and geeks who are excited about Ruby programming language ([http://ruby-lang.org/](http://ruby-lang.org/)) and Rails framework ([http://rubyonrails.com/](http://rubyonrails.com/)) and the joy they have brought back to web development. Our main goal is to share the love of the Ruby and Rails ecosystems with anyone that is interested. We cater to everyone, whether a non-programmer through advanced Rubyists. * We give lectures on programming topics * We freely provide decades worth of experience * For full details of this month's meeting please visit [http://columbusrb.com](http://columbusrb.com)

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. 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
