**Un espacio para tener conversaciones distintas, profundas y curiosas sobre preguntas que a todos nos inquietan.** **Para cualquier persona con ganas de pensar, compartir y conectar desde la curiosidad, sin necesidad de experiencia previa.** **¿Qúe es Hablemos Sin Saber?** Un espacio para tener conversaciones distintas, profundas y curiosas sobre preguntas que a todos nos inquietan. La idea no es encontrar la respuesta “correcta”, sino abrir nuevas miradas, cuestionar lo que creemos saber y enriquecer nuestra visión escuchando a los demás. En este taller sumamos un invitado especial: **ChatGPT**. Una vez elegido el tema, se le pedirá a la IA que lo defina o comparta una reflexión inicial, y a partir de esa definición se abrirá el debate grupal. **Objetivo:** * Despertar la capacidad de hacerse preguntas y reflexionar en colectivo. * Incorporar la mirada de una inteligencia artificial como disparador para abrir la conversación. * Escuchar y compartir desde el respeto, sin necesidad de convencer. * Salir con más preguntas que respuestas y con la sensación de haber vivido un diálogo significativo. **Metodología:** 1. **Inicio:** Cada participante propone un tema o pregunta que le genere curiosidad. * Ejemplos: * ¿Qué es el amor propio y como se confunde con el egoísmo? * ¿Existe la libertad o todo está condicionado? * ¿Qué es la realidad? * ¿Por qué buscamos certezas? 2. **Votación:** El grupo elige el tema del día. 3. **Intervención de ChatGPT:** Se le pide al modelo que dé una definición o una opinión inicial sobre el tema. 4. **Debate abierto:** A partir de esa respuesta, se abre la conversación entre los participantes, en un círculo de diálogo respetuoso. 5. **Cierre:** Reflexión grupal sobre qué nuevas preguntas surgieron y cómo cambió la mirada inicial. **¿Cuándo?** Nos reunimos una vez al mes. **¿Precio?** 5 Euros (incluye una bebida). Se abona por bizum, numero: 658857299 **Duración:** 1h 30 min aprox. **Lugar:** Casa Kokoro Dreta de L’exaimple (Solicitar dirección por mensaje privado)

Let's catch up and have a relaxed chat, including chat about the book Disability Visibility. This collection of essays is available at the library. You'll be invited to share the essay that you related to the most, and the essay that did the most to grow your awareness of something new. It's OK if you don't read the whole book!

**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 SOB is a ballet dancer. He’s the best ballet dancer that ever lived, and if I get a good chance I’ll kill him with my bare hands." - W.C. Fields In *City Lights*, Chaplin's Little Tramp meets a blind girl selling flowers who mistakes him for a wealthy man. When he learns that an operation may restore her sight, he sets off to earn the money she needs to have the surgery. He also befriends an alcoholic millionaire who only recognizes him when he is drunk. When the blind girl and her grandmother fall behind in the rent and face eviction, he tries working and even enters a boxing competition to raise the money they need. Regarded as Chaplin's masterpiece, *City Lights* has been ranked on more than seventeen "100 greatest movies of all time" lists. Orson Welles cited it as his favorite picture. *City Lights* is available for streaming on Amazon Prime, Hulu, HBOMax, Tubi and PlutoTV. The Columbus Library lists three copies on blu-ray and eight copies on DVD. Watch the movie on your own, then join us upstairs at East Market to discuss the film. If you want more, *Unknown Chaplin* is a three-episode lost-footage documentary available on Youtube. It covers his time on *City Lights* beginning at the twenty-six minute mark of episode two: https://youtu.be/f8960Uc15hI?t=1558

You can also join the meeting by Conference Call at (518) 263-8851.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
