Kommt am 2. Montagabend im Monat ins Offene Wohnzimmer zum Open Draw! Raucht Euch auch manchmal der Kopf von zu viel PC-Arbeit? Der Asphalt der Stadt ist heute wieder viel zu grau?

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

Together with Capgemini, we’d like to invite you to our talk in June. This time, we’ll be discussing spec-driven development with Simon Martinelli. **Spec-Driven Development in Practice: How AI Simplify Full-Stack Java** AI is transforming how we develop software, but many teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. What if specifications became the single source of truth instead? This session introduces Spec-Driven Development (SDD) and the AI Unified Process (AIUP), a practical approach in which developers write clear, structured requirements, and AI generates everything else: diagrams, code, and tests. When requirements change, the system stays consistent automatically. Based on a real-world Java project built with Spring Boot, jOOQ, and Vaadin, the most productive and secure web framework for Java, you’ll see how SDD keeps business rules, data access, and UI perfectly aligned. Join this session to learn how AIUP helps Java developers deliver applications faster, with less boilerplate and more focus on what really matters: understanding the domain. Most teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. In this session, you’ll learn how Spec-Driven Development (SDD) and the AI Unified Process (AIUP) let you define requirements once and generate consistent Java code, diagrams, and tests automatically. Based on a real project with Spring Boot, jOOQ, and Vaadin, this talk shows how to build faster, safer, and more maintainable full-stack Java applications. **Simon Martinelli** Simon Martinelli is a Java Champion, Vaadin Champion, and Oracle ACE Pro with over three decades of experience as a software architect, developer, consultant, and trainer. He is the creator of the AI Unified Process (AIUP) and a strong advocate of Spec-Driven Development. As the owner of Martinelli LLC, he coaches teams to get up to speed with AI-driven development. He regularly shares his insights through international conferences, articles, and his blog, Keep IT Simple (https://martinelli.ch), where he writes about AI, architecture, and modern Java development. He is also a lecturer at two universities in Switzerland, where he teaches software architecture, persistence, DevOps, and cloud-native development.

Liebe Deutschlernende, Das nächste Sprachcafé findet am **12.06.** von **15:30 bis 17 Uhr statt.** Das Thema: Wird vor Ort bekannt gegeben. Wir freuen uns auf euch!

Our June Meetup is coming up! Thanks to Snowflake for sponsoring us. **Please register with your real name and email addres and bring a photo id.** You will need to check in upon entry. We are happy to have David Wheeler as our speaker this time. David is ais a long-time PostgreSQL contributor, and creator of Sqitch, a database change management system; PGXN, the PostgreSQL Extension Network; pgTAP, a database test framework, and CITEXT2, the case-insensitive data type. After stints with PostgreSQL Experts, iovation, and The New York Times, he now works on PostgreSQL extensions for ClickHouse. He lives in New York City with his artist wife when they're not exchanging homes overseas. His talk is: *How to automatically release your extensions on PGXN* Today there is no one central distribution point for PostgreSQL extensions. The largest the extension source distribution service PGXN. It contains approximately a third of all known publicly-available extensions, but even those are not all up-to-date. PGXN aims to be the root registry for all extension releases, and plans to publish all releases to allow downstream registries to automate their build processes, as well. As such, it benefits extension developers and the broader PostgreSQL community when it contains up-to-date releases of all known extensions. I'll show you the process to set up PGXN distribution for your extensions, and the tooling to automate releases to keep it up-to-date. The main things to understand are Git, JSON, and GitHub workflows. At the end of the session, you'l have all the information you need to quickly and automatically publish your extension on PGXN.

Each session opens with a Soulbits oracle image setting the tone for the gathering we will move through. We will come together to honor the natural rhythms of rooting, rising, releasing, and receiving; the cycles that shape the soul’s journey. Through the four pillars of being: mindset, movement, connection & nourishment, we will create a space where imagery, sensation, and community weave together. Where the body becomes the guide, images act as mirrors, and the soul speaks. This circle is about noticing what rises, honoring what’s true, and reconnecting with the parts of yourself ready to be seen. This is a space to gather your scattered pieces, soften your body, and return to your truth with community by your side. Soulbits Circle is a reminder that every fragment of your story, every soulbit, belongs. Together we weave them into the blooming wholeness that you are. *Energy Exchange: 1-group $20-40 or 6-group $115* *Payment Options: Venmo or Cash* **Please RSVP to [Caitlynn](https://kalikwellnesswithin.org/) via** **email @ [kalik.wellnesswithin@gmail.com](mailto:kalik.wellnesswithin@gmail.com)** **text @ ‪(614) 407-4021‬** 💫

Join us as we discuss our June pick: Metal Slinger by Rachel Schneider! Book description: Even though she's not one of them, Brynn has spent her life among the Alaha, training to be a guard and waiting for the chance to attend the annual market hosted by the Kenta–the very same people who exiled her adopted community to a life at sea. Going to the market is a rite of passage eagerly anticipated by all young guards, but Brynn does not anticipate breaking a century-long peace treaty while there. Nor does she plan for the intense encounter with an enemy soldier that now threatens to unwind the fragile coexistence between their people–and everything Brynn once believed about herself to be true. Brynn's loyalty to the Alaha is tested when the truth of her identity is brought to light by this soldier who's taken an oath to bring her back to where she belongs. Narrowly escaping death on the violent high seas, Brynn's connection to the Alaha is further tested when she learns about the world of magic she's been denied. She was once certain of her fate and where she belonged, but the dark, knowing eyes of this stranger have her questioning everything, including her heart. Packed with knife fights and seafaring adventure, METAL SLINGER is the smash-hit start to the romantic fantasy duology, the Fire & Metal series
