Every Sant Jordi, Barcelona tells the story: A knight. A dragon. A freed princess. But in the original legend, the dragon isn't evil. It's a guardian. It's been protecting something, keeping it locked away, out of reach. Carl Jung said the same thing about the masks we wear. The curated versions of ourselves we show at work, with family, in a new city. They were never the enemy. They were protection. The problem is most of us forgot we put them on. In this 90-minute workshop you'll use guided journaling to meet the masks you've been wearing, find out what they've been protecting you from, and start to ask whether you still need them. No writing experience needed. Just you, a pen and paper.

🔧 Join us for **two talks** focusing on **getting more out of PHP** without unnecessary complexity, from async execution to performance insights. Stay for **discussion, drinks, and snacks** afterward. **Details** ⏰ Aptil 9th 🗓 Starting 6:30 pm 🇬🇧 Talks in English 🎟 Free 📍NN Working. Carrer de Pau Claris, 194, L'Eixample, 08037 Barcelona (4th floor) **Talks:** **1\. 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\. Topic:** PHP Performance Demystified - Measure, Understand, Optimize **Speaker:** [Volker Dusch](https://www.linkedin.com/in/volker-dusch/), Head Of Engineering at Tideways, PHP 8.5 Release Manager **About the Talk** In this talk, we'll explore options for PHP performance analysis. 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. From social networks to medical data processing, he has worked as an engineer, team lead, and Head of Engineering, mostly focusing on PHP, Go, C, JavaScript, HTML/CSS and System Operations. https://phpc.social/@edorian **Thanks to Manychat to host the meetup** – [Learn more](http://%5Bhttps/%5B%5Bmedium.com/manychat-engineering%5D%5D%5D(%5Bmedium.com/manychat-engineering%5D%5D)(%5Bmedium.com/manychat-engineering%5D%5D(medium.com/manychat-engineering%5D))(https:/%5B%5Bmedium.com/manychat-engineering%5D%5D(%5Bmedium.com/manychat-engineering%5D)(%5Bmedium.com/manychat-engineering%5D(medium.com/manychat-engineering)))) about Manychat Engineering – [Careers](http://%5Bhttps/%5B%5Bcareers.manychat.com/%5D%5D%5D(%5Bcareers.manychat.com/%5D%5D)(%5Bcareers.manychat.com/%5D%5D(careers.manychat.com/%5D))(https:/%5B%5Bcareers.manychat.com/%5D%5D(%5Bcareers.manychat.com/%5D)(%5Bcareers.manychat.com/%5D(careers.manychat.com/)))) at Manychat – [Videos](http://%5Bhttps://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d%5D(https://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d) "\[https://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d\](https://www.youtube.com/playlist?list=PLIfURI1S1wkA2sVy_AYtJcR_HyBpsTa2d)") from the previous meetups

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.

Join us for lunch at Cooper’s Hawk in Easton. If the weather is nice, we’ll enjoy lunch on their gorgeous patio!

**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
