Watcha reading?
Watcha reading?
Wondering what to read next? You wish to explore "Book X," but somehow "Book Y" catches your attention and holds your time hostage in pages. "Book Z," on the other hand, is the one you think you should read to *improve* your life, because only then does busy reading become busy living, and progress is assured! But what about when life is good enough to read for pleasure? Or bad enough to escape through fantasy? Do the books we choose shape our character? Or do they simply reveal what we already are? Too philosophical, I know… Ralph Waldo Emerson — whom I’ve never read — said: “I cannot remember the books I have read any more than the meals I have eaten; even so, they have made me.” This discussion aims to explore the reading choices we make and the connecting power of books: how they link people to ideas, ideas to ideas, and most importantly, people to people... Let’s meet and talk books.

Culinary exchange workshop
Culinary exchange workshop
Love food and meeting new people? Join us for a **Culinary Exchange Workshop** — a fun, hands-on cooking event where everyone brings a taste of their own culture to the table. **How it works:** * 👩‍🍳 Each participant submits one or more recipes — starter, main course, dessert, or even a drink. * 🗳️ We vote together to create our dream menu: one dish per category. * 🧺 We then organize who brings which ingredients, so everything’s ready for the big day. * 🏆 The 3–4 chosen chefs lead the group in preparing their winning dishes, guiding others through the recipe without cooking themselves. * 🍷 Finally, we cook, laugh, and share a delicious meal together in a warm, friendly atmosphere. Whether you’re a passionate cook or just curious to learn, this is the perfect opportunity to **discover new flavors, share your culinary traditions, and make new friends** from around the world.

Tea/Coffe, Chords & Collaboration: A Living Room Gathering
Hi, My living room will be open this **Sunday at 14:00** for a small, casual get-together. The idea is just to meet some fellow music-makers. No agendas, no prepared performances — just a chance to have a drink, chat and maybe play a few things together if we feel like it. **The Setup** * I’ll have some coffee, tea, water and small snacks. * There will be an e-piano, classical guitars, and an electric guitar with a basic amp here if anyone wants to use them. * Feel free to bring your own instrument if it’s easy to carry, but don’t feel like you have to. **The Details** * **Small Group:** Just **6 people** max so we can fit in fine. * **RSVP:** Please let me know by **Saturday at 19:00** if you can make it. * **Location:** I’ll message the address to the people joining me once the RSVPs close, but you can see where it is approximately on the map. * If it's difficult to get to that place, I could pick up from somewhere nearby before the start of the event. Looking forward!

Spec-Driven Development with GitHub Spec-Kit - Barret Blake
**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** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
