Graph Theory

In May, [Bruno Caballero](https://github.com/bruno-ah-um) will show us how to target hardware accelerators from Java with MLIR based on [his fork of the OpenJDK Project Babylon](https://github.com/bruno-ah-um/openjdk-babylon-mlir-tosa). Bruno leads the Java Virtual Machines Engineering team at [MicroDoc](http://www.microdoc.com), which develops JVMs and maintains ports across various processors and operating systems. In this talk, we’ll explore a toy project that translates Java code into MLIR for the TOSA dialect, which is used for AI and accelerator workloads. We’ll briefly introduce current approaches (e.g., TornadoVM and Babylon/HAT), before looking at how this project reuses existing compiler infrastructure instead of building new backends. Finally, we’ll touch on whether DSLs should be embedded in general-purpose languages like Java or designed as standalone languages. Small snacks and drinks will be available. There is always space for outside topics and discussions. If you have specific questions, please bring them. Looking forward to meeting everyone again!

### **MOUNTAINS – Stories about the climb** ### **Live Storytelling Night (Berlin)** “It is not the mountain we conquer, but ourselves.” — Edmund Hillary Some mountains are made of rock. Some are made of doubt, distance, language, love, grief, ambition, or simply getting out of bed when things feel heavy. This May, THE BEAR invites you to an evening of true personal stories about going uphill — about effort, resistance, resilience, and the quiet (or loud) voice that says: keep going. Our host, Izzy Ahrbeck, returns to Berlin fresh from the landscapes of Patagonia — where the mountains are wild, the wind is real, and every step reminds you that climbing is never just physical. Come as you are. Bring your uphill story. Or simply sit back and listen. We climb together. *** ### 🎤 What this event is An evening of **true, personal storytelling—told live on stage.** No scripts. No acting. No fiction. Just real people sharing real moments when life felt steep: * choosing the harder path * starting again from zero * pushing through thin air * reaching a summit that wasn’t what they expected * almost turning back Some stories will be funny. Some raw. All of them human. Music for the evening comes from Rory, adding sound and atmosphere to our climb. *** ### 💭 Why come? Because storytelling isn’t just entertainment—it’s connection. You’ll leave feeling: * more connected to others * reminded of your own experiences * maybe even inspired to tell your own story *** ### 🐻 How the evening works * **Open Stage** \- We randomly selected storytellers' name from our legendary top hat 👉 Want to tell a story? Put your name in the hat during the evening. First time? Even better. We’re known for being a welcoming space for new storytellers. *** ### 🎤 Want to prepare a story? If you’d like feedback before the event, you can send your idea to: 📩 hello@thebear-storytelling.de When booking, choose a **Storyteller Ticket** so we know you’re interested. 📍 **Venue:** Theatre Pool 📅 **Date:** May 21st 🕖 **Time:** 7:00 pm – 9:30 pm 🗣 Language: English (welcoming to all levels and backgrounds) *** ### [🎟 Tickets](https://www.thebear-storytelling.de/events/2026/05/21/mountains-stories-of-the-climb) Entry is **by donation** (Recommended: €15–20) https://www.thebear-storytelling.de/events/2026/05/21/mountains-stories-of-the-climb Give more if you can, less if you can’t. Everyone is welcome. *** ### 💬 Audience question of the night **Tell us about a time in your life when the path felt steep. What kept you climbing?** *** ### ✨ Final note Whether you’ve climbed mountains, careers, identities, relationships, or invisible inner walls — this night is for you. ## **Our Mission** ## *THE BEAR* **has grown into one of Berlin’s most beloved live storytelling events: a place where strangers become a community through the simple act of listening.** Supported by: [THE BEAR e.V. ](https://deref-web.de/mail/client/3fe0d0dh9KM/dereferrer/?redirectUrl=https%3A%2F%2Fthebear-storytelling.us6.list-manage.com%2Ftrack%2Fclick%3Fu%3Db5d7f087b587f8f081c447437%26id%3Dfc0e2d8df3%26e%3D711d4db9af), [Moving-Speaker.com](https://www.moving-speaker.com/), [Female Speaking Berlin](https://www.femalespeakingberlin.com/), and [Experience Berlin Youtube Channel](https://www.youtube.com/@Berlin-Videos).

PRINT / OBJECT by Atelier Māya This print exploration is a relaxed and social textile print session designed to help you slow down, explore, and create something uniquely yours. In this 2-hour workshop at Atelier Māya, you’ll be guided through a simple and enjoyable process: our unique flow test print session leading to a final textile piece. You’ll start by experimenting with our print tools, colour, and mark-making. In the Print Thinking process, you will get a feel for the materials without pressure. You will explore before creating your own composition. The session is intuitive and open. There’s no right or wrong way to work, and no expectation to be “creative” or experienced. Many participants are surprised by how quickly they settle into the process, letting go of perfection and simply enjoying the act of making. We’ll introduce you to Māya’s unique application tools and hand-mixed, eco-friendly studio inks, and support you throughout as you build your final piece. A variety of organic and cotton textile surfaces will be available, including the Māya Travel Pouch and Māya Maxi Tote. You’re also very welcome to bring your own light coloured, natural fibre textiles to experiment on. This is a calm, welcoming space to switch off, experience an analogue textile research atelier and try something new. You will spend a few hours creating in good company. No experience needed, come as you are. **Les Amis** is a women-only community of friendly souls. We provide access to hundreds of experiences that explore your passions and connect you with other event participants. **Check our website to learn more, and apply to join our community and events**: [lesamis.cc/apply](https://www.lesamis.cc/apply)

In diesem Workshop wagen wir uns an das vielschichtige Themengebiet *Liebe und Beziehungen* heran. Menschen sind Beziehungswesen: Zugehörigkeit, Verbundenheit, Nähe, Sexualität, Sicherheit und Geborgenheit zählen zu unseren Grundbedürfnissen. Für die meisten von uns ist eine erfüllte Partnerschaft eines der erstrebenswertesten Ziele im Leben. Wenn wir uns jedoch in der Gesellschaft und in unserem persönlichen Umfeld umsehen, scheint es, als wären wir kaum imstande, gesunde Beziehungen zu führen. Der Großteil von uns hat bereits mehrere Beziehungen hinter sich. Oft können wir nicht einmal klar benennen, woran sie gescheitert sind. Anhand der Erfahrungen, Beobachtungen und Interessen aller Teilnehmenden nähern wir uns den Fragen, die uns immer wieder bewegen. Wir erforschen, * was eine erfüllte Beziehung für jede:n bedeutet * was wir brauchen, um gelingende Beziehungen zu führen, * was uns dabei - persönlich und gesellschaftlich - im Weg steht, * und vor allem, wie wir daran arbeiten können. Wir forschen gemeinsam mithilfe des [re:nature® Kompasses](https://umainstitut.net/ueber-uns/renature-ansatz/). Dieses Lebensrad hilft uns dabei, komplexen Themen wie unseren Liebesbeziehungen eine Struktur zu geben. Angelehnt an die jahreszeitlichen Zyklen der Natur (Frühling - Sommer - Herbst - Winter) sind schließlich auch Beziehungen diesen Zyklen unterworfen: Verliebtheit - Commitment - Krisenzeiten - Trennung oder Neuausrichtung. Unser theoretisches Erforschen verbinden wir mit Übungen zur bewussten Körperwahrnehmung sowie mit kreativen Aufstellungen. Denn unser Ziel ist es, aus dem Erleben heraus neue Erfahrungen und Inspiration in die eigenen Beziehungen hinein zu tragen. Wir, Susanne und Ben, geben diesem Forschungsraum eine Richtung und einen Rahmen. Was dazwischen passiert, hängt von den Beiträgen der Teilnehmer:innen sowie der sich ergebenden Gruppendynamik ab. Persönliche Erfahrungen, drängende Fragen, Impulse und Ideen sind ausdrücklich erwünscht und sehr willkommen! Der Workshop ist offen für alle: ein inklusiver Raum für Menschen aller Geschlechtsidentitäten und sexuellen Orientierungen. Die Teilnahme erfolgt auf Spendenbasis. Bitte melde dich (zusätzlich) per Email an: [kontakt@benjaminpontius.de](mailto:kontakt@benjaminpontius.de)
