¿Qué hacemos? A las 20:00h tenemos una meditación budista guiada. La meditación tiene una duración de unos 25 minutos y es accesible y beneficiosa para personas de todos los niveles de experiencia. ¿Qué es el Camino del Diamante? El Buda dio instrucciones a tres clases de personas. Las primeras que deseaban evitar el sufrimiento recibieron las enseñanzas sobre Causa y Efecto, llamadas Camino Angosto (Hinayana). El segundo tipo de personas sentía la necesidad de beneficiar a los demás, por lo que les dio enseñanzas sobre compasión y sabiduría, llamadas Gran Camino (Mahayana). Finalmente a las personas que tenían una confianza sólida en su propio potencial y en de los demás, el Buda explicó enseñanzas del Camino del Diamante (Vajrayana). En este último nivel utilizamos métodos de identificación con la meta y actuamos como un Buda hasta que llegamos a ser como él. En el nivel más elevado, la meta, es el completo desarrollo de la mente, a lo cual denominó el Gran Sello (Mahamudra). ¿Quiénes somos? El Centro Budista Camino del Diamante de Barcelona forma parte de los más de 700 centros de meditación a nivel internacional de la tradición Karma Kagyu del Budismo Tibetano. Estos centros han sido fundados y guiados por Lama Ole Nydahl y su esposa Hannah Nydahl, de acuerdo con los deseos de H. H. XVI Karmapa. Ahora están bajo la guía espiritual de H.H. XVII Gyalwa Karmapa, Trinley Thaye Dorje. Nuestro centro está formado por personas que tienen sus propios trabajos e incorporan las enseñanzas y las meditaciones del Camino del Diamante en sus vidas cotidianas. Nuestros miembros comparten la responsabilidad de guiar meditaciones, contestar preguntas y dar explicaciones sobre budismo. Nuestro trabajo no es remunerado y se basa en el idealismo y la amistad. Realizamos noches semanales de meditación, que están abiertas al público y son gratuitas. Hay un ambiente social relajado y se animan las preguntas. Las meditaciones son guiadas en castellano, permitiendo que el espacio, la claridad y la alegría surjan naturalmente. Otras actividades incluyen charlas, enseñanzas y práctica personal. INFORMACIÓN COVID-19 A continuación revisa las medidas necesarias para asistir a la meditación: * Si tienes cualquier síntomas o no te encuentras bien, por favor abstente de venir.

Mi pasión por el básquet no se detuvo aquí, así que después de 8 años como jugador federado, quise ver el básquet desde otro prisma. Este, me llevo a trabajar de forma autónoma como arbitro en la Federación Catalana por mas de 4 años sobre las distintas regiones de Catalunya. Ahora, como profesional de la salud y el deporte con mas de 13 años de experiencia en el sector y tras mi regreso a Barcelona después de estudiar un postgrado de entrenamiento de alto rendimiento, crear esta escuela de básquet junto Alexis, es uno de los proyectos mas emocionante que he tengo en mi ciudad natal.

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.

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.

**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
