April Meetup is here! Let's gooo! We have some amazing speakers, and of course pizza and drinks will be available after the event. ────────── **18:30: Welcome** Grab a drink, and a seat until everybody arrives! **18:45 Intro by Host Neciu Dan** **19:00 Type safety across the network chasm** Speaker: [Alexander Vechi](https://www.linkedin.com/in/alvechy/), Product Engineer at SkyScanner Type safety often stops at the network boundary. In this talk, Alex will look at how modern frameworks try to bridge that gap, and share lessons from Skyscanner’s setup with protobuf-generated TypeScript types, including versioning, nullability, and validation to make API contracts safer in real frontend code. **19:25** **Building a Workflow Builder From The Ground Up** Speaker: [Martí Serra Molina](https://www.linkedin.com/in/ACoAADubmLMBJy_b_UNaB8Za17gbj1sc69JgkcY/?lipi=urn%3Ali%3Apage%3Ad_flagship3_profile_view_base%3BBKaAifpsSFG5%2BC062yD%2Blw%3D%3D) Frontend Engineer \| Creator of Formity Workflow builders are powerful tools for visually designing and automating complex processes, but building one from scratch in React poses unique challenges. Most teams reach for React Flow to handle node-based diagram rendering, yet there is still significant logic to build on top of it — a node layout algorithm, workflow state modeling, drag-and-drop, undo and redo, and more. In this talk, you will learn how to build a workflow builder from the ground up and the real-world complexities that emerge along the way. **19:50: Drinks and networking!** Do you want to talk at this meetup?

*Please Always contact me by whats app to book your space at the workshop, thank you!* What we' ll do You don't need to be an artist to join my creative art workshop! I'll be waiting for you outside the MACBA (The Barcelona Museum of Contemporary Art). From there, we'll take a walk to CCCB (The Centre de Cultura Contemporània de Barcelona), which has a café and co-working space. Once we get there, we'll ask for coffee/tea and get ready to embark on our creative journey! The art-making process will serve as a bridge for social and creative communication, and the theme will be centered around traveling and the things that make us vibrate. We'll start by using imagery, storytelling, and moving freely between drawing and writing to collage. We'll also work collaboratively, with each collaborator adding to a composition in sequence, allowing creativity to flow as we play. The main objective is self-expression, awakening creativity, having fun, and sharing a nice time together while colors and words come together to empower the artistic experience. I will guide you in the right direction to create something that you may have never thought of on your own, and you can take your own pace with art and bring it back home. The aim of this art workshop is to enhance your own creativity and self-expression. I will provide all the art materials, and the cost is 25 euros for a maximum of four people for a one-hour-long session. An individual session costs 40 euros.

Topic:** **PHP Fibers: simplifying async code and speeding up development** **Speaker:** [Max Fomichev](https://www.linkedin.com/in/maxim-fomichev/), Infrastructure Engineer at Manychat **About the Talk** We constantly search for creative ways to get maximum out of php, without bringing excessive complexity for our developers daily work. In this speech I'll sum up our way, describe where are we now in a bit, and share how we started to use fibers and asynchronous http requests to speed up both our code writing and execution, while avoiding excessive cognitive load for our developers dealing with "asynchronous" programming. **About the Speaker** Max has decades of experience in IT, primarily focused on programming in PHP and running Unix servers. For the past six years, he has been working at Manychat, a leading chat-marketing platform, where I combine the roles of an Infrastructure Engineer, SRE, and developer, optimizing systems and ensuring reliability. **2\.

From understanding how the PHP virtual machine and OPCodes work, to performing your own reliable and meaningful benchmarks, and how to use request profiling using open-source and commercial offerings. You will leave with an overview of the available tools and an understanding of how to use them in your day-to-day. Learning how to spot bottlenecks and optimize them away efficiently and confidently. **About the Speaker** With over 20 years of software development experience, Volker has seen PHP grow and mature from PHP 3, working on long-living custom applications in high-traffic environments.

### ¿Qué son las constelaciones familiares? Una constelación familiar es un método que nos permite dilucidar esos eventos que han podido causar un impacto profundo, a partir del cual, la armonía familiar se ha visto perturbada, estas dificultades pueden ser tanto de convivencia, de salud, de profesión, de pareja, etc. y sobre las cuales no se tiene control. A través de la puesta en escena que nos permite la constelación podemos tomar conciencia del origen del conflicto. Recreando la organización de la familia, o de cualquier otro sistema, las relaciones dentro del mismo se hacen visibles y con ellas las causas que han generado el conflicto pueden aclararse. Los participantes observaron como las dinámicas no resultaron les han estado aparecido, a veces, desde la infancia. Esa visualización y las propuestas de reparación por el terapeuta, rescatan al “paciente” de la culpa y le permiten recrear una nueva y liberadora imagen de solución. ### ¿Cómo puedo hacer mi constelación familiar? Hay dos formas de participar en este taller: 1. Como participar (que muestra los patrones inconscientes para el “paciente”) 2. Como “paciente” que recibe la Constela 3. Participar 20€ 4. Constelar 100€

*** **[QUÉ ES EL SOFTCOMBAT?](https://youtu.be/Essu82NpRvc)** **[¿Qué es el Jugger? | El Jugger, qué es y cómo jugarlo](https://youtu.be/dfyrlQn14oM)** **[¿Qué es el LARP?](https://youtu.be/fB3FkxDZhBA)** El Softcombat és una activitat esportiva en la qual, mitjançant armes encoixinades (conegudes com boffers), es recreen combats medievals, es practiquen jocs d'equip i s'aprenen moviments marcials de combat. El Rol en Viu consisteix a afegir-li una acció més teatral i dramàtica a aquests enfrontaments. Si t'interessa aprendre a combatre, emular les lluites de les teves pel·lícules favorites, lluitar amb espasa, subjectar un escut, dominar els secrets de l'equilibri de peus o fer fitnes d'un mode diferent; el Softcombat i el Rol en Viu són una activitat que has de provar. \*\*\* **REGLES BÀSIQUES PER AL SOFTCOMBAT** **NORMATIVA I SEGURETAT** la participació en un esdeveniment implica l'acceptació d'aquestes: Per a garantir la seguretat dels participants, totes les armes alienes a seran testades prèviament, conservant-se el dret a admissió de l'arma o de l'usuari.

SAM BASU IN-PERSON; NOTE: THIS IS THU, NOT TUE AS NORMAL Code is cheap, but software is expensive. Modern AI is a big opportunity to streamline and automate developer workflows for better productivity. There are some challenges though – AI Models often lack knowledge and AI Agents need expertise/guidance to reliably pull off complex workflows. Context is everything for modern AI and you can bring it. Model Context Protocol (MCP) aims to provide a standardized way to connect AI Agents to different data sources, tools and non-public information - the point is to provide deeply contextual information/expertise to AI. Skills are higher-level behaviors and instructional guardrails, that define how and when AI Agents should leverage tools to accomplish something meaningful. Subagents in AI are specialized, task-focused agents designed to handle specific, well-defined tasks within a larger AI system. In terms of the food industry: AI Agent = Chef 👨‍🍳👩‍🍳 MCP Tools = Raw Ingredients 🥔 🥩 Skills = Recipe Cards 📝 📇 SubAgents = Sous Chef 🔪 🍳 Loops = Door Watcher 💂👀 Developer = Restaurant Owner 👑. So, what should developers use to bring context and guardrails to make AI work their way? Well, it depends and sometimes, the answer might be whatever combination makes developers most productive. With official SDKs and well-thought-out guidance, it is a breeze to work with MCPs, Skills or SubAgents. Developers could bring their own data, APIs, services, coding patterns and structured guidance to make AI Agents work their way. And AI Agentic workflows work the same way in IDEs or Terminals, paving the way autonomous ways of getting work done with AI. With contextual expertise to light up unique coding workflows, AI Agents can make developers ultra productive – upwards and onwards.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

HeroPress has grown to be a worldwide phenomenon, giving voice to people from dozens of cultures, countries, and backgrounds. This is the story of how it grew from a plea from a young man in India to a source of inspiration for hundreds of thousands of people.

**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** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
