**\>\>\> Registration takes place on Luma: [https://luma.com/yp90isjd](https://luma.com/yp90isjd)** **Welcome to KREATIV UNTAPPED #1 – Storytelling Untapped w/ Ben Sauer** **A hands-on session. No slides. Just your stories.** We couldn't be more excited to tap into this with you at Thoughtworks Berlin. *Follow us on [LinkedIn](https://www.linkedin.com/company/kreativ-untapped) and [Instagram](https://www.instagram.com/kreativuntapped).* **KREATIV UNTAPPED** is a creative playground born in Berlin — and we're kicking off with the discipline that sits at the heart of every other one: **storytelling.** Because here's what AI can't replace: the human desire to create. Creativity is what makes us uniquely human — it's a muscle, and like any muscle, it needs training. Most of us have stopped. **KREATIV UNTAPPED** is where we change that — through hands-on sessions with working practitioners across visual arts, tactile crafts, narrative & sound, and spatial & performative disciplines. **This evening** is about words, voice, and presence. In a world full of decks, dashboards and screens, we've forgotten how to just… tell a story. This evening is a practice in putting the slides away and using the oldest tools we have — your voice, your hands, your story. **Expect a short provocation from [Ben](https://bensauer.net/), a hands-on session with a sketching element to flex that creative muscle, a round of group sharing, and time to actually meet the people in the room.** **Who's this for?** Anyone with a story to tell — and the willingness to tell it without a slide deck. No job title. No prior experience. Just the willingness to tap in. Creativity untapped. Connection for real. \-\-\- **ABOUT [BEN SAUER](https://bensauer.net/)** Ben Sauer is a speaker, author, and coach who teaches the art of strategic storytelling — and the perfect person to launch this series. He's the author of "Death by Screens: How to Present High-Stakes Digital Design Work and Live to Tell the Tale" — a go-to resource for designers, product people and creatives who want to stop boring their audiences and actually be heard. Ben spent years as a UX designer at Clearleft, then as Director of Product for AI at Babylon Health, leading a team of 100 on products worth $100m+. He has trained teams at NASA, Amazon, and the BBC, and spoken at The Economist, NEXT Conference, UX London, VW + Audi and dozens more — frequently as the audience's top-rated speaker.

A web that is private, resilient, and beyond the control of a few central powers. Like forests, decentralized systems derive strength from what lies beneath the surface: dense networks of roots, sharing resources without hierarchy, and coordination that persists even when individual nodes disappear.* ​*DWeb Camp: Root Systems invites participants to build technologies that–like living ecosystems–adapt, regenerate, and endure.* ​*The event will be held at Alte Hölle, just one hour southwest of Berlin. The venue sits on the grounds of a forest hotel dating back to the 1800s. Once a Stasi recreation site, Alte Hölle is now owned and inhabited by a collectivist community of friends who are turning this space into a sustainable venue for group events of technologists, hackers, artists, and activists. Set on 100,000 square meters of lush meadows and ancient forests, Alte Hölle is both a community and location with values that resonate deeply with DWeb, a place we are excited to nourish and leave richer than when we arrive.* ​\~ *Want to learn more about DWeb Camp?

**Embodied Consent** mit **Karl-Henrik** für **LGBTIQA+** Kostenlos mit[ ](https://wearevillage.org/shop/embodied-consent/w20-2026/)**[Anmeldung](https://wearevillage.org/shop/embodied-consent/w20-2026/)** **Lernen über Grenzen und Kommunikation** Wenn Sie noch nicht an einem Workshop zum Thema Consent im Village teilgenommen haben, ist es jetzt an der Zeit! Dieser Workshop ist sehr zu empfehlen für alle, die unser Projekt regelmäßig besuchen oder an einem unserer Workshops teilnehmen möchten. Diese Erfahrung wird Ihnen nicht nur helfen, sich in der we.are.village-Community zurechtzufinden, sondern sie wird Sie auch dazu befähigen, diese Werte in Ihr Leben zu übertragen. Sich seiner Grenzen bewusst zu sein und sein Einverständnis oder Nicht-Einverständnis auszudrücken, sind wichtige Fähigkeiten im Leben, aber wir haben nicht oft die Gelegenheit, die Fähigkeit des Einverständnisses auf die gleiche Weise zu üben wie andere Fähigkeiten, wie Singen, Sport treiben oder eine Sprache lernen. Bei Consent geht es um viel mehr als ein einfaches Ja oder Nein. Wenn wir die Zustimmung dekonstruieren, entdecken wir, wie wir unsere wahren Wünsche kommunizieren können, und hören auf, Dinge zu wählen, die wir nicht wollen. Durch Diskussionen, Bewegung und Partnerspiele werden wir Werkzeuge entwickeln, um körperliche Wünsche auszudrücken und zu verhandeln und durch praktische Übungen Grenzen zu setzen. Dieser Workshop ist für Menschen aller Körpergrößen, Geschlechter und Hintergründe offen und einladend. Es handelt sich um einen nicht-sexuellen Workshop bei dem, ohne Druck, Kommunikation und Berührung geübt werden können. Es geht genauso darum, wirklich Ja zu sagen und es auch so zu meinen, wie es darum geht, Nein zu sagen! Wenn Sie noch nicht an einem Workshop zum Thema Consent im Village teilgenommen haben, ist es jetzt an der Zeit! Diese Erfahrung wird Ihnen nicht nur helfen, sich in der we are village Community zurechtzufinden, sondern sie wird Sie auch dazu befähigen, diese Werte in Ihr Leben zu übertragen. Gemeinsam wollen wir eine auf Consent ausgerichtete Gemeinschaft mit gemeinsamen Werten aufbauen und dabei die Verantwortung des Einzelnen für die Einhaltung dieser Grundsätze betonen. Unser oberstes Ziel ist es, gesunde Beziehungen zu fördern und eine integrative Community für eine bessere, vernetzte Zukunft zu schaffen. 🔵 **Embodied Consent** with **Karl-Henrik** for **LGBTIQA+** Free **[Registration Required](https://wearevillage.org/en/shop/embodied-consent/w20-2026)** **Learning about boundaries and communication**. If you have not yet attended a workshop on Consent in the Village, now is the time! This workshop is highly recommended for anyone wishing to visit our project on a regular basis, or to attend one of our workshops. This experience will not only help you navigate within the we.are.village community, but it will also equip you to carry these values into your life. Being aware of your boundaries and expressing your consent or non-consent are essential skills in life, but we don’t often get a chance to actually practice consent skills in the same way we practice other skills, like singing, playing sports or learning a language. Consent is about much more than a simple yes or no. When we deconstruct consent, we discover how to communicate our true desires and stop choosing the things we actually don’t want. Through discussion, movement and partner games, we will build tools to express and negotiate physical desires and set boundaries through the use of practical exercises. This workshop is inclusive and welcoming to individuals of all body sizes, genders, and background. This is a non-sexual workshop, and great, low pressure situation in which to practice communication and touching. It’s as much about how to truly say yes and mean it as it is about saying no! If you have not yet attended a workshop on Consent in the Village, now is the time! This experience will not only help you navigate within the we are village community, but it will also equip you to carry these values into your life. Together, we aim to nurture a consent-centered community with shared values, emphasizing individual responsibility in upholding these principles. Our ultimate goal is to foster healthy relationships and create an inclusive community for a better, more connected future.

Wie jedes Jahr versammelt sich die Bitcoin-Community in Berlin, um den legendären „Bitcoin Pizza Day“ zu feiern. Die Transaktion von Laszlo Hanyecz gilt als eine der ersten bekannten Zahlungen mit Bitcoin für reale Güter: 10.000 Bitcoin im Austausch gegen zwei große Pizzen. Zur Feier dieses historischen Moments treffen wir uns dieses Jahr im Restaurant Viale dei Tigli. Auch dort werden Bitcoin-Zahlungen akzeptiert und natürlich gibt es Pizza. **Bitte beachtet: Jede Person bezahlt ihr Essen und ihre Getränke selbst vor Ort.** Das Ganze ist als lockeres Get-together ohne feste Agenda gedacht – einfach zusammenkommen, austauschen und gemeinsam Pizza essen. Wir freuen uns über viele Teilnehmer. Da die Plätze begrenzt sind, bitten wir um möglichst verbindliche Zusagen. Vielen Dank.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

**Abstract:** This is a practical playbook for building a production-grade data lakehouse. It walks through foundational principles — naming conventions, least-privilege access, automated CI/CD testing — before diving into medallion architecture. Furthermore, metadata-driven design patterns show how configuration tables and dynamic notebook orchestration eliminates hard-coded pipelines. The deck covers star schema modeling, guidance on choosing between Spark, Pandas, and SQL, and data quality enforcement using DQX with YAML data contracts. Finally, we dive into security best practices and performance optimizations. **Host:** Justin Shea, Mehdi Jeddi, Erik Pak, and Sou-Cheng Choi **Talk Format:** This is a hybrid event.
