Desalineación: vivir una vida correcta que no se siente propia
Desalineación: vivir una vida correcta que no se siente propia
Hay personas cuya vida funciona. Responsabilidades cumplidas. Decisiones razonables. Un camino que, visto desde fuera, parece lógico. Sin embargo, algo por dentro no termina de encajar. No hay un gran problema que señalar. Pero tampoco hay una sensación clara de dirección propia. A veces no se trata de estar perdido. Se trata de haberse adaptado demasiado. La desalineación aparece cuando la vida que sostienes es coherente con lo que se espera… pero no necesariamente con lo que eres. En este encuentro exploraremos cómo se construye esa desconexión silenciosa, por qué muchas personas tardan años en detectarla y qué señales indican que estás viviendo desde la adaptación más que desde la elección. Durante la sesión abordaremos: – Cómo identificar decisiones que tomaste para encajar más que para elegir – La diferencia entre estabilidad externa y coherencia interna – Qué señales aparecen cuando tu vida funciona pero no te representa – Por qué adaptarte constantemente puede alejarte de ti mismo – Cómo empezar a recuperar criterio propio sin romper lo que ya has construido. Este encuentro está dirigido a personas que sienten que su vida es correcta, pero no termina de sentirse propia. A quienes han seguido caminos que parecían adecuados y ahora empiezan a cuestionar si realmente los eligieron. No se trata de destruir lo que has construido. Se trata de empezar a habitar tu vida con más conciencia. Porque una vida que funciona no siempre es una vida alineada. Formato: Presencial Duración: 2 horas y 15 minutos Hora: 10:45 – 13:00 Aportación: 5 € (gastos de organización) Este es un evento colaborativo junto al grupo “El Club de las Mentes Brillantes”, creando un espacio compartido para explorar el desarrollo personal desde una perspectiva práctica y consciente.

Route 3 - Street Photography Workshop / Taller de Fotografía de Calle
Route 3 - Street Photography Workshop / Taller de Fotografía de Calle
ENGLISH (Spanish below! PS, please let me know if you cannot view the event pricing!) * First, we will meet, greet and go over the route map and objectives for about 15 minutes. There will be a basic talk about things to look for and specific things to shoot for each objective. * We will go over the map and then spend time walking the route stopping and shooting in each area. We will be walking for a total of about 2 hours. The main focus of the workshop is to learn about and gain more confidence shooting street photography with the bonus of exploring and seeing some interesting spots around Barcelona. * Once we're finished the route we will meet at a cafe (if we want!) to speak about the objectives, answer any questions and close with any comments or remarks 20 minutes. * In total we will spend about 2.5 hours in this street photography workshop. Other things to note * You should know the basics of photography and how your camera works. We'll discuss street photography techniques, not learning how to use cameras. * Bring the min amount of things required for a few hours of shooting. (ie. camera and a few € for food etc, thieves are a real problem everywhere so always be careful). * PLEASE BRING >> POSITIVE VIBES *** ESPAÑOL * En primer lugar, nos reuniremos, saludaremos y repasaremos el mapa de la ruta y los objetivos durante unos 10 minutos. Habrá una charla básica sobre las cosas que hay que buscar y las cosas específicas que hay que fotografiar para cada objetivo. * Repasaremos el mapa y luego pasaremos un tiempo caminando por la ruta parando y disparando en cada zona. Caminaremos durante un total de 2 horas. El objetivo principal del taller es aprender y ganar más confianza en la fotografía de calle con la ventaja de explorar y ver algunos puntos interesantes alrededor de Barcelona. * Una vez terminada la ruta nos reuniremos en una cafetería (¡si queremos!) para hablar de los objetivos, responder a cualquier pregunta y cerrar con cualquier comentario u observación 20 minutos. * En total dedicaremos unas 2.5 horas a este taller de fotografía de calle. Otras cosas a tener en cuenta * Debes conocer los fundamentos de la fotografía y el funcionamiento de tu cámara. Hablaremos de técnicas de fotografía callejera, no de aprender a usar las cámaras. * Trae la cantidad mínima de cosas necesarias para unas horas de fotografía. (es decir, cámara y algunos euros para comida, etc., los ladrones son un verdadero problema en todas partes). * ¡¡POR FAVOR TRAIGA >> VIBRAS POSITIVAS NOTA: ¡Mi español es tan, tan, no increíble pero puedo explicar las cosas en español si es necesario! :) (Note: My Spanish is so so, not amazing but I would be happy to explain things in Spanish if needed!)
PHP Talks #7: Mastering PHP Execution
PHP Talks #7: Mastering PHP Execution
🔧 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

ReactJS Barcelona - April 2026
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?

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
