Hi and welcome to our next Socrates Café philosophy meetup! Do you have a hunger for deeper understanding of yourself and the world? Do you value deep, honest and respectful dialogue? If yes, then this meetup will be very interesting for you. • WHAT IS A MEETUP ABOUT? We ask, answer and discuss questions and ideas to stimulate critical thinking and to widen our perspectives with new concepts and thoughts. The main purpose of these meetups is to enrich ourselves with the perspectives of others, not to convince others about our own perspectives. Our meetups are about our own philosophies of life and not necessarily what the great philosophers and academics have said or written. It is not a debating club or a platform for proselytizing. Instead, we place the emphasis on questioning, open mindedness and challenging our own assumptions while listening to and respecting the views shared by others. A Socrates Café meetup is considered a success when participants leave a discussion with many more questions than they had at the beginning. • WHAT TOPIC IS DISCUSSED AT THE MEETUP? Participants suggest topics at the beginning of each meeting. We then vote and choose that event's most popular topic for discussion. No academic training in philosophy necessary; just enthusiasm for exchanging ideas and points of view. Some examples of subjects chosen on previous meetups: * What ideals are worth dying for? * Why are we never satisfied? * Why is it that human beings know that the society is going wrong, leaders are well informed about it and things continue as is? * Is identity necessary? * How can it be that people in democratic societies are so obsessed with power? (Desire to be different, better, stronger than others) * What is friendship? • WHO PARTICIPATES AT THIS MEETUP? Anybody is more than welcome to join our meetups. Our events gather people from different backgrounds, different cultures, while no philosophical background is mandatory. Our usual participants are people that have a hunger for deeper understanding of themselves and the world. People that value deep, honest and respectful dialogue. The inspiration for Socrates Cafe originates with the book of the same name, written by the philosopher Christopher Phillips. (Socrates Cafe: A Fresh Taste of Philosophy, 2002). Phillips felt that the Socratic method of dialogue and discussion should be practiced not just in academic settings, but among everyday people interested in examining deep questions together. Hundreds of Socrates Cafe groups now exist around the world.

This talk digs into how Kibble—Rover's design system—handles the gap between platforms through a file-naming convention (`.tsx` / `.native.tsx` / `.common.ts`), a unified event abstraction that bridges web click and native press events, and a token pipeline that generates Swift, XML, CSS, and TypeScript from a single source of truth **19:25 React Native in a Native App: Brownfield Integration & Over-The-Air Deployments** Speaker: [Luca Barone](https://www.linkedin.com/in/lucabarone95/) Mobile Engineer at Rover.com A practical look at how Rover.com ships React Native screens inside fully native iOS and Android apps — without rewriting them from scratch. We'll cover the "brownfield" integration pattern, how JS and native code communicate through bridge modules, and how we deploy JavaScript updates to users in minutes using Expo EAS Update, completely bypassing the App Store review cycle. **19:50: Drinks and networking!** Do you want to talk at this meetup?

**PERCUSIÓN CORPORAL Y VOZ** **SALA AGLAYA** **Calle Bellver, 11 (Gràcia)** **Miércoles de 20.15 a 21.30h** Valor: 15 € La música más original del mundo! La creada en el momento. Una invitación a jugar a través de la música. Una invitación a hacer música con nada más y nada menos que tu propio cuerpo. Este taller nos permite conocer múltiples posibilidades sonoras de nuestro cuerpo, combinarlas y jugar con ellas, incluyendo, además de lo puramente percutivo, la voz como elemento rítmico y melódico. Aprenderemos ritmos de diferentes estilos musicales al mismo tiempo que dejaremos espacio a la improvisación y a la creación individual y colectiva a través de juegos y dinámicas variadas. El principal objetivo es aprender de forma lúdica por medio de esta práctica musical y crear un espacio que nos permita explorar y enriquecer nuestra musicalidad.

**TORNEM A LA CIUTADELLA!!** **NO us equivoqueu de lloc!** **[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 embuatades (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. **És durant el matí de 11h a 13.30h quan major quantitat de participants es reuneixen.

¡NUEVA ACTIVIDAD! Vamos a hacer una salida nostálgica, **muy barcelonesa**, que seguro que hace muchos años que no experimentas: un recorrido con las tradicionales embarcaciones "Golondrinas" del Puerto. Así pues, hemos preparado un recorrido histórico por el Puerto de Barcelona, a pie y en Golondrina (**la tradicional embarcación**), en el que conoceremos más detalles de su historia y veremos rincones y zonas que **son difíciles de contemplar si no se hace desde el mar**: el muelle de pescadores, el faro de Montjuïc, las dársenas de Sant Bertran o el Moll d'Espanya. El paseo en Golondrina tradicional durará unos 45 minutos y posteriormente seguiremos con una ruta guiada por la zona del Port Vell, l**a Barceloneta** y el Barrio de la Mercè. Sin duda, una actividad ideal para un domingo por la mañana, en la que volveremos a hacer de barceloneses "de toda la vida". Y como siempre, nuestras actividades **contienen explicaciones de un guía licenciado en historia por la UB.** ¡No te lo pierdas! Éste es nuestro **PLAN**: 1. Encuentro en la salida de Metro Drassanes (L3) en el centro de la Rambla e iniciamos ruta! 2. Una vez situados históricamente, nos vamos sacar los billetes para las Golondrinas. 3. Recorrido de 45 minutos navegando por el Puerto de Barcelona y Montjuïc. 4. Seguimos la ruta cultural a pie por el Port Vell, el Barri de la Mercè y la Barceloneta. 5. Terminamos en la Barceloneta, y l**os que quieran, pueden ir a tomar algo (opcional).** **PRECIO**: 20 euros correspondientes a los honorarios de guía licenciado en historia, billete Golondrinas y paseo histórico

**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Jonathan Stevens **Polymorphic Association - The Good, the Bad and the Ugly** When Active Record works, it’s great. Polymorphic associations in Active Record promise elegant flexibility: one interface, many possible models. When they work, they feel almost magical. But when your application grows and real‑world complexity sets in, that magic can quickly turn into confusion, broken queries, and performance headaches. We’ll explore where polymorphic associations shine, where they silently introduce technical debt, and why even experienced Rails developers can end up wrestling with unscoped queries, tricky joins, and hard‑to‑optimize relationships. We’ll walk through real examples of tangled polymorphic logic—and more importantly, show practical strategies to refactor, untangle, or even avoid these pitfalls entirely. By the end, you’ll know when to reach for polymorphism, when to run away from it, and what to do when your complex query simply refuses to cooperate. **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!
