🔧 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

Realizamos Taichi al aire libre aún asi solicitamos que debido al CoViD cada participante decida libremente y se responsabilice de las medidas que desee tomar respecto a la situación sanitaria actual El Taichi es una arte marcial basado en la filosofía taoísta y en su visión del universo, que además de fomentar habilidades marciales, ayuda a mejorar la salud, la conciencia corporal y puede ser un camino para el desarrollo personal y espiritual de los que lo practican. Este arte marcial es diferente a la mayoría de las que podáis conocer. Mientras otras se basan en la fuerza y la potencia el Taichí es una respuesta a la pregunta: ¿Por qué combatir la fuerza bruta con más fuerza cuando es posible aprovechar la de tu adversario? Si estas pinceladas os llaman la atención podéis venir a conocer el Taichi de forma gratuita, cada domingo de manos del Sifu Albert Sala. Las clases son de 9 a 10:30 de la mañana en el parque situado al final del Carrer Lleida delante del recinto llamado “El mercat de les flors” (cerca de las paradas de metro “Plaça Espanya” y “Poble Sec”). Somos razonables en la práctica del Taichi y os ayudaremos a no realizar prácticas que puedan provocaros un daño pero en última instancia cada participante es responsable de si mismo y os pedimos que nos comuniquéis problemas de salud o lesiones que pudiesen causaros perjuicio alguno. Además os repetimos que debéis velar de forma adulta y consciente de vuestro bienestar y por tanto os hacemos responsables en ultima instancia del mismo. We practice Taichi out in the open but been aware of CoViD we want for each practitioner to take the mesures to protect themselfs in the corrent situation the way they see fit under their own responsibility. Taichi is a martial art based in the Taoist philosophy and its vision of the universe, in addition to the improvement of the martial skills of its practitioners, helps to enhance their health, their body awareness, and also can be a path for their personal and spiritual growth. This martial art is set apart from the majority of the other ones you may know. Other martial arts are based in strength and muscle power, but Taichi is instead an answer to the question: ¿Why fight strength with strength when you could use their power against them? If these bits have caught your attention you can come to know Taichi for free, all Sundays taught by Sifu Albert Sala. The lessons start at 9:00 am and run throught 10:30 am in the parc that is at Lleida Street (Carrer Lleida) in front of the building called “El mercat de les flors” (It’s near de subway stations of Plaça Espanya and Poble Sec). We encorage a rational training of Taichi and will help you to prevent posible injuries in its practice. But you have to be conscius and responsable of yourself so we ask of you to comunicate with us any posible health problems or injuries that may be bring harm to you during training. However you have to be aware and concious of your well-being and therefore we hold you ultimately responsible for it.

**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

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.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way.

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!
