RSVP on Luma: https://luma.com/zx2l0ais?utm_source=meetup Silent Reading / Creating Club is a gathering for people who enjoy focusing together in public. Bring a book, a notebook, a sketchpad, knitting needles — whatever you’d like to spend a quiet hour with. All projects and all participants are welcome. ​This year is about creating more — quietly, consistently, imperfectly — and shaping environments that support that. If you’re building something of your own, you’re especially welcome here. ​We’re building a community of readers and creators who value depth, presence, and shared silence. The magic isn’t just in the quiet hour — it’s in the people who return and make it feel like a familiar room. ​(Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist.) ​This quiet ritual unfolds at **W66 Café**. ​There’s no entrance fee, but please order at least one item from the café and don’t bring outside drinks 🙂 ​No assignments. No pressure. No productivity race. Just a shared hour of intentional silence, followed by relaxed conversation. 🕰 Our Agenda ​**10:30 – 11:00** Arrivals, ordering drinks/food, light social time ​**11:00 – 12:00** The Great Quiet Hour (Read. Write. Sketch. Code. Think. Sit.) ​**12:00 – 12:30** Optional socializing — share what you were reading or creating, or simply continue in quiet focus. ## **​🏡 House Guidelines** ​To keep this space calm and welcoming for everyone: ​• Silence during the focus hour (no calls or conversations) • Phones on silent mode • If using a laptop, please avoid meetings or audio — headphones welcome • Arrive before 11:00 if possible to minimize disruptions

Am letzten Samstag im Monat Februar wollen wir uns wieder treffen im Restaurant Cinque in der Reinhardtstraße 27d um 16 Uhr und ein bisschen netzwerken. Bitte sagt Bescheid, ob ihr wirklich kommt. Bitte beachtet die Speisekarte und dass es etwas teuerer ist 🤔🫣 https://www.ristorante-cinque.de/speisekarten/ Wir werden uns austauschen, vernetzen und schauen, wo wir dich bei deiner Idee unterstützen können, falls du noch nicht gegründet hast. 👜📝 Es kann auch über vermögensverwaltende GmbHs sowie Holdingstrukturen gesprochen werden. 🤑💎 Ich selber habe erst vor wenige Monaten gegründet und kann dir praktische Tipps geben z.B. zum Thema Kosten beim Notar, Amtsgericht, Dauer bis zum Eintrag im Handelsregister und warum es sich manchmal lohnt nicht seine private Adresse als Geschäftsadresse anzugeben. 🤐🧐 Hinweis: Getränke und Speisen zahlt jede Person vor Ort selbst. 🫠

A small NEXUS gathering built around movement rather than discussion alone. This is for high-bandwidth Mavericks who spend most of their time in conceptual thought and need some physical counterweight. Why bouldering? Because it’s deliberate: short problems, full focus, and immediate feedback. You’re on the wall, solving something tangible. The mental noise drops instantly! Conversations happen naturally in between climbs. No pressure, you move at your own pace. Some exchanges stay light. Others go deep. Both are fine. This is not about athletic achievement. It’s about presence, recalibration, and being around people who don’t require you to shrink or translate yourself. Come as you are. Try some bouldering problems. Rest when needed, and engage where it makes sense. **Bring comfortable clothes and climbing shoes if you have them (rentals are available at the gym).** *Registration equals commitment. If you sign up, you show up. Read the group description first and decide consciously. For context about NEXUS, visit our* ***[website](https://thenexusformula.com)*** *and* ***[newsletter](https://news.thenexusformula.com)****.*

The GLOBALS Tech Festival 2026 (#GSTF26) on March 1, 2026 in Barcelona is more than just a conference; it is a dynamic gathering where the global tech and growth community comes to connect, learn, and evolve. Think of it as a melting pot where founders, CxOs, operators, investors, and ecosystem builders converge in a relaxed and friendly setting, with the spirit of learning and connecting at its core. 🙂 Taking place in Barcelona right before MWC & 4YFN, this year’s GLOBALS Tech Festival builds on the legacy of the former Global Sales Tech Festival and takes it to the next level: from “just sales” to growth across tech, SaaS, e-commerce, finance, telco, health, marketing and edtech. You will spend a full day surrounded by people who actually get what you are building: exchanging playbooks, testing ideas, and forging collaborations in a laid-back but high-intent environment. Expect stages, curated sessions, and serendipitous encounters that feel more like a festival than a conference. The focus of GLOBALS Tech Festival 2026 is on fostering genuine connections and exchanging fresh, practical ideas over real conversations, accompanied by good food and drinks. Expect to leave buzzing with new contacts, strategies you can implement on Monday, and a renewed hunger to scale your impact. Let’s create an unforgettable experience filled with inspiring people and breakthrough insights. Key Highlights 💡 Content-Driven Insights Absorb cutting-edge perspectives on tech, AI, growth and go-to-market from global experts, founders, C-level leaders, and trainers. 🌐 Network Expansion Build valuable connections across a curated professional community of tech entrepreneurs, investors, and ecosystem players from Europe and beyond. 🎉 Enjoy the Experience Immerse yourself in a vibrant atmosphere that fuses learning, collaboration, and entertainment, all in the heart of Barcelona before the world lands for MWC. Explore Our 5 HUBS 🤖 Tech Hub Dive into digitalization, automation, AI, tools, CRMs, and the tech stacks that power modern growth. 🤝 Partnering Hub Connect with consulates, chambers of commerce, associations, and media to open new markets and amplify your brand. 📢 Customer Hub Hear real success stories and customer experiences that reveal what is actually working in the field. 💼 Talents Hub Meet startups, scaleups, corporations, job agencies, and recruiters to explore roles, collaborations, and advisory opportunities. 📚 Education Hub Learn new methodologies, techniques, and tips from educators, trainers, and practitioners focused on modern sales and growth. Each hub is tailored to offer a deep dive into a specific dimension of tech-driven growth, so every attendee can design a journey that fits their role and ambition. Event Format A compact, high-energy festival day including: Multiple stages with keynotes, panels, and fireside chats Roundtables and small-group sessions for honest, tactical exchange Curated networking & matchmaking moments An afterparty to lock in the strongest connections of the day (Exact schedule and program blocks are available on the official website.) This Year’s Theme “Celebrating Growth” In 2026, we zoom out from pure sales and look at growth in all its forms: Growth of companies (revenue, teams, markets) Growth of people (skills, leadership, resilience) Growth of impact (AI, sustainability, and tech as a force for good) We explore how technology, data, and human experience blend to build resilient, sustainable, and globally connected businesses. Who Is Behind GSTF26? GLOBALS Tech Festival 2026 is brought to you by Club GLOBALS, the Growth Acceleration Club for tech founders and innovators, together with its global community of partners and ecosystems. With more than 200 events hosted and 50k+ contacts across tech hubs like Barcelona and Berlin, GSTF26 is the flagship stage of a year-round platform of events and the GLOBALS On Tour series.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
