**💶 Wertschätzungsbeitrag: 10-20 Euro (nach eigenen Möglichkeiten)** . **Du möchtest Deine Freundschaften, Partnerschaft & Arbeitsbeziehungen verbessern? Dieser Worskhop kann ein großer Schritt dazu sein.** . Beziehungs- und Bindungstypen sind ein weit verbreitetes Modell, um typisches Verhalten in verschiedensten Beziehungen erklären. . Warum klammert jemand? Warum Drama? Warum Rückzug? Warum Kälte? Warum Unsicherheit, Nervosität und Ärger? --- und wie sieht eine sichere & gute Beziehung aus (und fühlt sich an). . Die Annahme: Ereignisse der frühen Kindheit & der Erziehungsstil unserer Eltern prägen, wie wir als Erwachsene unsere Partnerschaften, Freundschaften & Arbeitsbeziehungen leben. . Für manche gut. Für manche weniger gut. . Ich setze mich mit den Beziehungstypen auseinander, weil ich glaube, dass sie einen wesentlichen Einfluss auf die Gestaltung von Freundschaften haben (und auf Liebesbeziehungen sowie Beziehungen jeglicher Art). . Dabei habe ich entdeckt, dass ich oft einen ***vermeidenen Beziehungsstil*** habe: ich weiche lieber aus, trenne mich oder spreche Probleme nicht an, weil ich wahrscheinlich in meiner Kindheit aus unterschiedlichen Ereignissen gelernt habe... dass bringt eh nichts, ich kann anderen nicht vertrauen, das macht man nicht, meine Bedürfnisse sind nicht wichtig, usw. . **Wie geht es Dir? Eher ängstlich oder vermeidend?** **Oder, wie sagte ein Bekannter: Sicherer Bindungsstil mit Features.** . In der Auseinandersetzung mit den Beziehungs- / Bindungstypen habe ich bemerkt, wie gut es mit tut, mich mit anderen mich darüber auszutauschen. . **Vielleicht geht es Dir genauso?** **Oder willst Du die Bindungsstile erst einmal kennenlernen?** . . **🎁 Das kannst erwarten** Ich lade Dich zu diesem Workshop ein, damit Du einen weiteren Schritt Richtung mehr Leichtigkeit & Ehrlichkeit in Beziehung gehen kannst. . 💬 **Agenda** Folgendes haben wir vor: 18:15 Uhr - Doors Open & Ankommen 18:30 Uhr - Start des Workshops * Wir lernen uns kennen * Eine Einführung zu den Bindungsstilen * Ein Fragebogen zu Deinem Bindungsstil - in Beziehungen oder Freundschaften. (Dein Ergebnis bleibt anonym, wenn Du willst) * Fragen & Antworten Danach orientiert sich das Programm etwas an den Bedürfnissen der Teilnehmenden, doch es wird etwas so werden: * Austausch über den eigenen Bindungsstil * Was kann ich tun, um mich weiter dem sicheren Bindungstil anzunähern? 21:30 Uhr - Ende . Zwischendurch machen wir eine kleine Pause. . Meine Erfahrung ist: Austausch & Offenheit hilft, mit sich selbst und anderen relaxter zu werden. **⏰ Die Türen sind offen ab 18:15 Uhr.** Mantel aufhängen, Toilette, eine Runde schwatzen und los ... Komm am besten schon 18.15 Uhr. 📋 **Kann ich mich vorbereiten?** Du musst Dich nicht vorbereiten. Wir haben oft eine Bandbreite an Teilnehmenden: Newbies im Thema bis hin zu Therapeuten (tatsächlich!). . **Wenn Du magst, empfehle ich dieses Buch:** * **[Buch: Warum wir uns immer in den falschen verlieben](https://amzn.to/498A9js)** (Werbung, Amazon-Link // Als Amazon-Partner verdiene ich an qualifizierten Verkäufen) . Ich habe das Buch auch gelesen und finde es eine leicht verständliche Einführung in das Thema ([Meine Rezension](https://abenteuer-freundschaft.de/rezension-warum-wir-uns-immer-in-den-falschen-verlieben)). Der Workshop wird sich an dem Buch orientieren. . . **❓ Darf ein zweites Mal kommen?** Ja, sehr gern. Ich halte es sogar für sinnvoll, mehrmals zu kommen, wenn Dir der Workshop gefallen hat: * Das Thema vertiefen * die eigenen Beobachtungen aus den letzten Wochen verarbeiten * sich mit neuen & alten Bekannten über das Thema weiter austauschen. . **🏠 Der Veranstaltungsraum** * Wir haben einen wunderschönen Raum im Kieztreff in Berlin Mitte (mit sauberen Toiletten!). * nähe Hackescher Markt. Sehr gut mit den Öffis zu erreichen. * Wenn Du vor Ort ankommst, ist alles ausgeschildert. . **🎒 Das bringst Du mit ...** * Etwas zu trinken (z.B. deine Wasserflasche, keinen Alkohol!) * Wenn Du magst: Zettel und Stift. * Du solltest satt sein und vorher gegessen haben * Bargeld für den Wertschätzungsbeitrag (10-20 Euro) . 🚫 **Was ist der Workshop nicht:** Der Workshop ist kein therapeutisches Angebot. Dafür bin ich nicht ausgebildet (noch nicht mal im Selbststudium). . . 🧑🏼 **Mehr über mich:** Seit 5 Jahren forsche ich zu guten Freundschaften, wie man diese aufbaut & vertieft. Du erfährst mehr über mich auf [www.abenteuer-freundschaft.de](www.abenteuer-freundschaft.de). . Auf Meetup findest Du Freundschafts-Workshops, Wanderungen, Spaziergänge, Männerabende, Frauen-Freundschafts-Workshops und Themenabende zu Vertiefung psychologischer Fragen. . Außedem bin ich ausgebildeter NLP-Lehrtrainer ([DVNLP](https://www.dvnlp.de/)) & Coach. **Ich freue mich Dich zu sehen und auf einen interessanten, efahrungsreichen Workshop!** \-\-\-\-\-\-\-\-\-\-\-\-\- **🌳 Vielleicht auch für Dich interessant:** **📘 Befreiung von Scham & Schuld:** Dieses Buch geht an die Wurzel von Kindheitsprägungen sowie dysfunktionalen Glaubenssätzen und Beziehungsdynamiken (Auch die Bindungsstile kommen darin vor). Weil das Buch so tiefgreifend & interessant ist, gibt es eine Austausch-Runde. Wir treffen uns zirka alle 2 Monate (siehe Veranstaltungen bei Meetup in der Gruppe). Das Buch findest Du auch auf Amazon: * **[Buch: Befreiung von Scham & Schuld.](https://amzn.to/4rkDPoR)** (Werbung, Amazon-Link // Als Amazon-Partner verdiene ich an qualifizierten Verkäufen) \-\-\-\-\-\-\-\-\-\-\-\-\-\- **👋🏽 Get in touch & stay in touch:** **✈ Telegram-Kanal: [t.me/abenteuer_freundschaft](http://t.me/abenteuer_freundschaft)** für Events, Workshops & Termine **✉ Freundschafts-Newsletter:** [https://abenteuer-freundschaft.de/newsletter](https://abenteuer-freundschaft.de/newsletter) Alle 4 Wochen das Neuste aus der Freundschaftsforschung; oft seltener, nämlich nur dann, wenn es wirklich etwas zu berichten gibt. **🔥 6 Zutaten großartiger Freundschaften** Seit 2020 forsche ich, was großartige Freundschaften wirklich ausmacht.

Meet us for in-person talks at Zalando on February 17, 2026! Join us for an evening of practical talks on how GenAI is reshaping modern engineering workflows, from code agents to production-grade, guardrailed systems. Please make sure you register with your full name, as it will be checked by security on arrival. **📅Date and Time:** Tuesday, February 17, 2026 Doors open: 18:00 Opening & announcements: 18:30 Talks start: 18:35 Wrap-up & networking: \~20:30 📍**Location:** [Zalando Office BHW](https://maps.app.goo.gl/GELYd8FH7AnqEFNF8) Berlin Hedwig-Wachenheimstraße 7 (BHW) The main entrance is on the west-side of the building (towards Uber Arena). Participants should register at the Helpdesk, and will be picked up from there. 📝 **Agenda:** **18:00 – Doors Open** Pizza, drinks, and networking **18:30 – Opening** Short welcome and announcements from the organizers (5 min) ### **18:35 – Talk #1** **Building Blocks of Modern Code Agents: Reusable Skills and Role-Based Subagents** **[Alexey Grigorev](https://www.linkedin.com/in/agrigorev) — DataTalk.Club** A practical map of modern code agent types and the two key building blocks that make them reliable in real-world development workflows. Code agents appear in many forms today: chat-based assistants, cloud agents running CI-like workflows, and IDE or terminal agents embedded directly into development environments. In this talk, we’ll map these main categories, discuss what each is good at, and highlight where they commonly fail. We’ll then zoom in on two core building blocks used in modern agent tooling: * **Skills / playbooks** — reusable, step-by-step workflows (e.g. understand the repo → implement a change → run checks → produce a clean diff) * **Subagents** — specialized roles such as planner, implementer, reviewer, and tester that split complex work into focused, reliable steps **Format:** 20 min talk + 10 min Q&A ### **19:05 – Talk #2** **Guardrailed Agents at Scale: Zalando’s Support Agent for Incident Triage and Stakeholder Q&A** **[Ivan Potapov](https://www.linkedin.com/in/ivan-sur/)**, **[Saugandh Karan](https://www.linkedin.com/in/saugandh-karan/)**[ ](https://www.linkedin.com/in/saugandh-karan/)— Zalando SE We’ll share how Zalando built and shipped a specialized internal support agent that helps engineering teams answer stakeholder questions and triage operational alerts — without drowning in context or compromising production safety. The agent enriches user requests with relevant observability context (metrics, logs, traces, recent deploys), summarizes what matters, and produces a severity assessment with recommended next steps. A key challenge is context explosion: pulling “all the data” quickly becomes noisy, slow, and risky. We’ll walk through the architecture patterns and guardrails that keep the system production-ready: * Retrieval and ranking strategies * Strict tool boundaries * Policy-driven response formats * Evaluation checks to prevent overconfident or unsafe guidance Finally, we’ll cover rollout and migration: introducing the agent alongside existing workflows, aligning it with architecture guidelines, and iterating based on real incident feedback. **Format:** 20 min talk + 10 min Q&A ### **19:35 – Pizza, Drinks & Networking** Invite your friends and join our meetup. Special thanks to our hosts **[Zalando.](https://en.zalando.de/?_rfl=de)**

Hallo, Willkommen zur Handarbeits- und Gesprächsgruppe! Wir treffen uns von 14 bis 16 Uhr in der Psychosozialen Initiative Moabit. Bei Kaffee/Tee und Kuchen sitzen wir in entspannter Runde zusammen und arbeiten an Strick-/Häkel- oder anderen Handarbeitsprojekten oder ähnlichem und kommen so auch gerne ins Gespräch. Alle sind herzlich willkommen (auch ohne Strickerfahrung!!). Wir haben vor Ort auch ein paar Stricksachen und Wolle, die alle mitbenutzen können :) Hello, Welcome to the crochet/knitting group at Psychosoziale Initiative Moabit! We meet up every Wednesday from 2 to 4pm and all work on our creative projects. Throughout the crafting you have the space to talk and expand your community in Berlin. Everyone is welcome (even if you've never done crocheting/knitting before!!). We also have some knitting needles and yarn for you to use :)

Join us for the next Spring User Group Berlin meetup! This time, we are bridging the gap between rock-solid operations and developer joy. **Talk 1: Secure and Seamless: Injecting Kubernetes Secrets into Spring Applications** *Speaker: Dmitriy Goi, Deutsche Bank* Look, we’ve all done it. You need a database password, so you throw it into an environment variable and call it a day. It works, it’s fast, and your app starts up. But then the security audit hits, or your credentials rotate and suddenly your logs are full of connection errors because your Spring context is stuck in the past. At Deutsche Bank, "good enough" usually isn't. I’ve spent the last few years moving Spring apps into Kubernetes and realizing that most tutorials lie to you. They show you the easy way, not the way that survives in production. I’m going to show you why environment variables are a security trap and how mounting secrets as files actually works (and where it breaks). We’ll get into the mess of secret rotation, why you probably need a CSI driver or an External Secret operator, and how to make Spring Boot actually pick up those changes without a manual restart. **About the speaker:** A passionate software engineer at Deutsche Bank, Dmitriy brings 8 years of development experience to his focus on modernizing application development. He specializes in Spring Boot and Kubernetes and is currently helping lead the charge on migrating key applications to a hybrid cloud environment, emphasizing secure and efficient engineering practices. \-\-\- **Talk 2: Adopting Kotlin for Spring 7: Cleaner Code, Fewer Bugs, Some Tradeoffs** *Speaker: Daniil Tsarev, JetBrains* Kotlin is becoming a first-class citizen in the Spring ecosystem, especially with the latest features in Spring 7. In this talk, we'll explore how easy it is to adopt Kotlin in existing Spring projects, what tangible benefits it brings to everyday development, and where some edges still are. Expect practical examples, real-world tradeoffs, and an honest look at whether Kotlin is the right choice for your Spring stack. **About the speaker:** Daniil Tsarev is a Software Developer at JetBrains with over 10 years of experience working with the Spring ecosystem. Previously was developing a Spring-based full-stack framework for enterprise solutions. Now passionate about developer productivity, he’s dedicated to creating tools and solutions that make developers’ lives easier. **📅 Agenda** [**18:30**]: Doors open, food, drinks & networking [**19:00**]: Talk 1: Secure and Seamless (K8s Secrets) [**19:45**]: Short break [**20:00**]: Talk 2: Adopting Kotlin for Spring 7 [**21:00**]: Q&A and more networking [**22:00**]: Closing the doors Come for the knowledge, stay for the community.
