Rethinking Java for Accelerators: A Toy MLIR/TOSA Compiler with Bruno Caballero
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!

🎤 **Building AI Agents with Python: Approaches & Challenges**
🗓️ When? **Thursday, May 21 from 6:15pm**
📍Where? **d-fine**
📚 Get ready for a practical session this month, as we will extend a multi-agent’s capabilities together
**Anne Sehnal** and **Cassandra Milbradt** invite you to an exciting, highly relevant workshop on agentic systems in the era of LLMs. The session covers core concepts including capabilities, multi-agent architectures, and tool usage, with a hands-on look at popular Python libraries and enterprise tools for building agentic systems. Participants will get practical experience by extending a multi-agent setup using pydantic-ai and pydantic-graph. The demo-agent that will be extended was built by our speakers to enhance your learning experience.
Prerequisites: Medium to advanced Python proficiency and an interest in agentic frameworks.
✨ **Cassandra Milbradt** holds a Master's and PhD in Mathematics from Humboldt-Universität zu Berlin. Her early involvement in a student consulting company set the tone for a career spanning machine learning, AI, software engineering, and energy markets. Today, she joins Anne to present "Building AI Agents with Python: Approaches & Challenges".
✨ **Anne Sehnal** holds a Master’s degree in Chemistry and Business Studies, with a focus on energy systems modelling and battery technology. Starting from complex system simulations, she moved into data analytics and now designs data architectures, building analytics platforms for energy companies, including in energy trading. Today, she joins Cassandra to share perspectives on building and applying AI agents on robust data foundations.

Board Games, Picnic & Connections for people in their 20s
Join us this Thursday at Treptower Park for a cozy evening of board games and connection!
The mission of Quarter Life Connections is to create spaces for **young people in their twenties** to connect and feel at home in Berlin - especially once the familiar structures of university life stop being there and work life starts.
We will start with a quick get-to-know-you round and then split up into smaller groups for games. After up to 2 hours of playing we will close with a check-out-and-stay-in-touch round. The intention is to have fun while getting to know the people around you and form start building connections that will last after the event is over.
**Please be on time!** The intro circle sets the tone for the event and is a huge support for making meaningful connections.
BRING YOUR OWN GAME - and stuff
We will have enough games there to entertain everyone - but maybe you have a game at home you think would be fun to play together? Bring it!
Also any addition of **picnic blankets** or **snacks** are very appreciated :)
CONTRIBUTION

KREATIV UNTAPPED #1 – Storytelling Untapped w/ Ben Sauer
**\>\>\> 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/)**

Blood on the Clocktower at Manifesto! (beginner/intermediate)
Hi folks, this is the meetup group for the weekly Sunday Blood on the Clocktower games in the Soot bar in Manifesto at Potsdamer Platz. We run beginner-friendly and intermediate-level games throughout the afternoon and evening. **Friendly newcomers of all skill levels are welcome, no experience required!**
Our group aims to provide a fun and welcoming space to experience this thrilling game of social deception. **We focus on promoting a positive and fun group atmosphere, where players don’t take themselves or the game too seriously, whether they’re heroically winning or spectacularly losing.** Our players follow the code of conduct for the Berlin Board Gamers group and are expected to treat each other with respect and consideration – “killing with grace, and dying with dignity”.
We are usually able to offer two simultaneous games on Sundays. If you are marked as "attending" in Meetup and are in your seat at 15:00, your place is guaranteed for as long as you want to stay. All other seats are first come, first served. We always run at least one beginner-friendly game of the basic version of Clocktower ("Trouble Brewing") throughout the afternoon and evening. We also usually have enough players for a second intermediate-level game. If you are already very familiar with Clocktower, consider also joining our Tuesday meetup for advanced players, when we play with complex custom scripts and characters.
Blood on the Clocktower is a deep, mechanical game of murder and mystery, lies and logic, deduction and deception… think Werewolf on steroids. Each player receives a unique secret role and plays either for the good team – the uninformed majority, gathering info and working with others to solve the puzzle – or the evil team, the informed minority, scheming to eliminate good players and protect their demon from execution. In our beginner games no prior experience is expected and we will gladly explain the game rules to any newcomers.
We play in English so players should be able to understand and express themselves in English: an exception is possible for one pair of players willing to play together (as a “Revolutionary” pair) where one player can interpret into and out of English. Please let us know in advance if this is the case.
We are very grateful to the wonderful folks at Manifesto for hosting our meetup! **Please support the venue during your visit by buying drinks and/or food.**
Programmiercafé
A space for working on projects & learning new stuff together. 💻☕️
Please RSVP if you intend to join, as we have limited space. 😊
Bitcoin Pizza Day
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.

**FAQs**
**Our Community Backyards workshops are FREE and a great way to participate in the rebate program. Our workshops are typically 1 to 1 and a half hours long and held in-person. Our workshops cover the same content as the online course, but they are more detailed and allow the chance to ask questions and have discussions with the presenters and other residents. We occassionally have "advanced topics" classes where you dive deeper into one topic of Community Backyards such as invasive vs. native plants or rain gardens.**
**Registration is encouraged but not required.** You can register in advance to receive your voucher at the workshop. If you don't register in advance, that's okay - you can still show up (unless otherwise noted - which is very rare) and sign up for a voucher at the class, and we will send you one via email or mail within a few business days after the workshop.
**"Do I have to be a resident of that community to attend that workshop?"** Nope! Our workshops are open to everyone (unless otherwise noted - which is extremely rare). You can attend a workshop that best suits your schedule even if it is in a different community than your own.
**"Why is registration closed?** Can I just show up?" Yes, you can show up without registering! We close registration typically 1-2 days before the workshop to give the vouchers and materials to the presenters. However, you are always welcome to just show up and fill out a short form to request a voucher at the workshop. If eligible, we will send one to you within 1-2 business days after the workshop.
**Voucher note**: Classes are free for everyone but vouchers are for residents of Franklin county or participating community (list here: https://www.communitybackyards.org/participate)
