Continuous Integration

**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)** *[Qase](https://qase.io) is presenting the **eleventh** Meetup on Quality Engineering in Berlin.* *This time, we’re bringing you three deep-dive talks — all designed to challenge the way you think about quality, testing, and collaboration.* *As always, expect great conversations, snacks, and drinks. See you there!* **AGENDA** **1\. Mitesh Patel\, Technical Consultant \- Scientific Instruments @ Altum Solutions: *Food QA: Testing Tasting*** On this fine evening, we shall enjoy some food … and also learn why we enjoy it. Because tasting is really a form of testing for our brains — wetware QA in essence. But how do we reformulate this wetware testing into those familiar realms of software and hardware testing? It is not as simple as exchanging taste buds for test suites and bites for bytes. Just ask Big Food which spends billions on this same question: How can computers do taste tests like humans? Guided by the example of an ML/AI-powered scientific instrument for chemical analyses, namely, a spectrometer, this session addresses this question and explores the broader topic of QA in the food industry. Discover how food companies scale testing across scientific software, device hardware, and food/human wetware. So grab a spoon for this insider scoop on QA for food. **2\. Vitaly Sharovatov\, developer advocate @ Qase: *QA Myths Busting: A Practical Guide to Higher Quality*** Have you ever felt the urge to increase the amount of testing or hire more testers, thinking it would improve product quality? As a tester, have you ever been held “accountable” for quality or pressed for time, leaving you feeling helpless? Or perhaps you’ve been asked to justify quality assurance initiatives with numbers? Our industry is filled with myths: from “quality can be measured” to “more testing means higher quality” and from “QA slows down work” to “testers are responsible for quality”. In this talk, I will present the myths I once believed, explain the dangers they pose to both teams and products, and demonstrate how they should be debunked and overcome. **3\. Asya Isakova\, Co\-Founder @ TECH_Connect: 𝘌𝘢𝘳𝘯 𝘛𝘳𝘶𝘴𝘵\, 𝘒𝘦𝘦𝘱 𝘠𝘰𝘶𝘳 𝘑𝘰𝘣** The job market is wild: it’s hard to get hired, and sometimes even harder to stay hired. In a new role (or a new team), one of the fastest ways to reduce uncertainty and accelerate collaboration is to build trust quickly. But how do colleagues and managers decide you’re trustworthy? It’s rarely just about closing Jira tickets or moving cards on a Kanban board. People assess trust through patterns of behavior: what you do, how consistently you do it, and how do you act towards others. In this talk, you’ll learn an evidence-based approach to building trust at work using three practical components: integrity, reliability, and benevolence. We’ll unpack what shapes people’s trust judgments (including context, risk, and prior experiences) and translate research into concrete behaviors you can apply immediately: especially in multicultural and cross-functional teams.

**Only for Women** \| Group \| Twice per month Thursdays 18:30 – 21:00 \| MahaYoga Zentrum Berlin **Upcoming** * 5th of March 2026 * 26th of March 2026 * 9th of April 2026 * 23rd of April 2026 * 21st of May 2026 * 4th of June 2026 * 25th of June 2026 * 2nd of July 2026 * 23rd of July 2026 * 6th of August 2026 * more dates will follow **About** This group is about embracing your inner strength, cultivating self-love, and awakening the fullness of who you are.

From the very beginning, I have immersed myself in a spiritual women’s group, which has been a profound source of support and growth. Yoga and Tantra Yoga have brought incredible balance, harmony, and a deeper understanding of myself, truly transforming my life. Throughout my journey with the traditional integral Yoga system, I’ve learned practical ways to bring calm and balance into daily life, even in challenging times. Completing my Tantra Yoga for Women Instructor Training was a turning point, as it allowed me to blossom in ways I hadn’t thought possible. Being surrounded by a nurturing sisterhood showed me the immense power of women uplifting one another, and I now feel called to share this path with other women who seek similar transformation. In this **Tantra Yoga for Women** group, I am excited to lead you through these teachings, helping you connect deeply with your feminine energy and support your blossoming into fullness and joy. Together, we’ll create a safe and sacred space where you can embrace your own potential, find balance, and build bonds with a supportive community of women. I look forward to sharing this journey with you! **Price per month** Normal: 30,00 € ***Note:*** Over Meetup you can only sign-up for the first month for 10,00 €.

Zalando is graciously hosting us for our first Meetup in 2026. And we are doing it a bit different: we have two rooms, and two talks in parallel. This gives you the opportunity to choose between two talks, for a total of four talks. This year, we’re especially happy to welcome Amazon Web Services as the food sponsor for our meet-up. Thanks to their support, our community can enjoy great conversations over great food — making the evening not only insightful, but also delicious. Meet the AWS experts Sikandra Chaudhary, Daria Aleshkova, and Narendra Tawar. Narendra will be delivering a talk on PostgreSQL and AI, sharing practical insights and real-world experience. We truly appreciate AWS’s commitment to supporting local tech communities and helping us create a warm, welcoming atmosphere for everyone. **PLEASE BRING YOUR PHOTO ID** **USE THE MAIN ENTRANCE TO BHW ON THE SIDE OF UBER ARENA** **Agenda** Two sessions run in parallel in rooms codenamed "Auditorium" and "Festival" **18:30** \- doors open: registration\, networking\, and drinks **19:00 - 19:05** Auditorium, "Event intro" by Sergey Dudoladov, Senior Database Engineer in Zalando. **Auditorium: Track A** **19:10 - 19:55** "How we made WarehousePG Open Source (again)" by Andreas 'ads' Scherbaum, a WarehousePG Principal Engineer at EDB and a Founding Member of PostgreSQL Europe **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups" by Tudor Golubenco, CTO of Xata **Festival: Track B** **19:10 - 19:55** "The Role of PostgreSQL in the AI World" by Narendra Tawar, Sr Database Specialist SA, AWS **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "Modernizing Postgres Communication with Hackorum", by Kai Wagner, Percona **21:00 - 22:00 Networking, Q&A, and pizza** **22:00 - The End** **Abstracts** **How we made WarehousePG Open Source (again)** WarehousePG is an Open Source fork of Greenplum Database, which by itself is a fork of PostgreSQL. The project was born after the upstream project was made closed source. This talk gives a quick overview of the history of both projects, which already spans more than two decades. We then dive into the reasons for creating a fork, and all the stumbling stones we had to pass in order to make this project open source again. We also talk about the challenges of CLAs (Contributor License Agreements) and what implications the PostgreSQL and Apache Licenses have for the project. Speaker: Andreas 'ads' Scherbaum **The Role of PostgreSQL in the AI World** As artificial intelligence (AI) continues to revolutionize industries, the need for robust, scalable, and efficient data management solutions has never been greater. PostgreSQL, with its extensibility, performance, and advanced data capabilities, plays a crucial role in enabling AI-driven applications. This talk explores how PostgreSQL supports AI workloads, from managing vast datasets and integrating with machine learning frameworks to leveraging extensions like PostgreSQL ML, TimescaleDB, and JSONB for AI-ready storage and querying. Attendees will gain insights into best practices for using PostgreSQL in AI pipelines, optimizing performance for AI inference, and harnessing the power of open-source innovation to drive intelligent decision-making. Whether you're a data engineer, AI researcher, or PostgreSQL enthusiast, this session will showcase why PostgreSQL is an essential component in the AI ecosystem. **From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups** CloudNativePG (CNPG) is a popular and battle-tested operator for running Postgres on top of Kubernetes. At Xata, we’ve been using CNPG and extending it in several different directions. One of them is implementing a scale-to-zero plugin: clusters hibernate when inactive and they wake up automatically when new connections are created. After adding scale-to-zero, we’ve faced the challenge that the CNPG wake-up from hibernation is rather slow.This is an optimization story about how we reduced the wake-up times from 20+ seconds to under one second. Speaker: Tudor Golubenco **Modernizing Postgres Communication with Hackorum** In 2026, the debate over whether mailing lists are still "state of the art" continues to divide developers. While some view them as relics, we cannot neglect the unique benefits of their decentralized, archival nature. Rather than fighting over platforms or ignoring the friction, Hackorum asks a simpler question: Why not just improve the user experience? Hackorum transforms the daunting mailing list "firehose" into a modern, forum-style interface without breaking the underlying email culture. It is designed to lower the barrier for new contributors while providing power tools for veterans: Seamless Integration: Real-time sync between mailing lists and daily sync of the Commitfest status. Modern UX: Per-message read tracking, tagging, and contributor profiles. Enhanced Coordination: Shared notes and mentions to streamline complex reviews. We have to stay open minded and willing to expand our horizon and as such Hackorum is rapidly evolving. While our roots are in development, we are currently expanding to include broader mailing lists like -general and -docs. Our goal is to make the entire Postgres ecosystem more accessible and usable for everyone. Join us for a demo of the latest updates and help us shape the future of Postgres communication. Speaker: Kai Wagner **About the speakers** **Andreas Scherbaum** has been working with PostgreSQL since 1997. He is involved in several PostgreSQL related community projects, member of the Board of Directors of the European PostgreSQL User Group and also wrote a PostgreSQL book (in German). Since 2011 he was working for EMC/Greenplum/Pivotal and tackled very big databases. Until 2024 he was doing the same - but with maybe even more and bigger databases - for Adjust GmbH in Berlin. Now he's working at EDB as WarehousePG Principal Engineer and is helping customers with even larger databases. **Tudor Golubenco** is the CTO of Xata, a Postgres platform with branches and zero-downtime, reversible schema changes. Before Xata, Tudor worked as a tech lead at companies like Elastic and Oracle. **Narendra Tawar** \- Sr Database Specialist SA I am accomplished database professional with 21 years of comprehensive experience across Oracle, PostgreSQL, Microsoft SQL Server, and MySQL environments, with specialised PostgreSQL expertise since a decade.

Ready to flex your architectural muscles… with a new twist? Join us for our first **AI-Enabled Architectural Kata**, where we'll tackle a real design challenge together, using generative AI as a collaborator in the architectural process. Small teams will work through a complex scenario, but this time each team gets a unique **AI collaboration role** that shapes how they interact with AI during the session. Expect lively debate, creative solutions, plus an honest reflection on where AI helps and where human judgement still reigns supreme. **Mark your calendars for Thu, Mar 5,** and join us at **Thoughtworks Event Space** for an engaging evening dedicated to software design and architecture. Whether you're a seasoned architect, an AI-curious developer, or just passionate about software design, this meetup is the perfect platform to share, learn, experiment with new ideas and meet passionate people. **Event Schedule** * **18:15** – Doors open for snacks, drinks, and socialization * **18:45** – Introduction * **19:00** – **AI-Enabled Architecture Kata**: Small teams' work session * **20:30** – Presentations by teams **❓ What is an Architectural Kata?** Inspired by the concept of “Code Kata,” Architectural Katas are exercises that allow architects to practice their skills in a real-world scenario. It's about honing our craft in software design through practical, hands-on challenges in small groups. Read more about Architectural Katas on [Neal Ford](https://nealford.com/katas/about.html)'s website or on the [original Katas site](https://www.architecturalkatas.com/) by Ted Neward. **What makes this one AI-Enabled?** Building on the classic Architectural Kata format, this edition adds a new dimension: **AI as a team member**. Each team receives a unique role card that defines how they collaborate with AI during the session. The goal isn't to see who can prompt the best. It's to explore together how AI changes the way we think about, discuss, and communicate software architecture. **What to bring** Please have access to at least one AI tool on your phone or laptop (Claude, ChatGPT, Gemini, or similar). We'll provide a short prompting cheat sheet for architectural AI collaboration to get you started. No prior experience with AI for architecture work is needed! **Venue** **Thoughtworks Event Space**, Revaler Str. 31, 10245 Berlin *(Please note that this is a different entrance from the Thoughtworks office located at Revaler Str. 29)* **Sponsored by Thoughtworks** A big shout-out to [Thoughtworks](https://www.thoughtworks.com/) for sponsoring our event and supporting our mission to foster a tight-knit community of software design practitioners. **Code of Conduct** We adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/) to ensure a welcoming and respectful environment for all participants. **Spread the Word** We believe the more, the merrier!

**Meditation – One Hour of Presence (All levels) by STUDIO B (https://www.studio-bewusstseinserfahrungen.de/)** This one-hour meditation session is suitable for beginners as well as experienced practitioners. We begin with a short and gentle breathwork exercise to regulate the body, calm the nervous system, and bring attention inward. This prepares the transition into meditation. This is followed by a 15–20 minute introduction to the meditation practice. During this phase, I explain the core principles of meditation and assign each participant a personal meditation task, tailored to their individual level of experience. The intention of this part is to create clarity, inner orientation, and a sense of safety for the silent practice. We then enter a first phase of silent meditation. After approximately 15–20 minutes, the silence is intentionally interrupted by a short walking meditation. This is not a break, but a conscious transition that integrates the body, releases restlessness, and deepens presence. Afterwards, we return to silent meditation. Each participant practices independently with their personal instruction, within a calm and supportive space. This session invites you to cultivate presence, quiet the mind, and either deepen an existing meditation practice or begin one in a grounded and accessible way. **Open to all levels. No prior experience required.** Payment is for the room. ​ \*\*\* ​Session structure - **duration: 60 minutes** **1\. Arrival & Breathwork \| 5–7 minutes** Gentle, regulating breathwork to calm the nervous system and gather attention. **2\.

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

Drake Lundstrom is presenting: Code Anywhere by Talking to your Phone Abstract: Have you heard the trend of people deploying code anywhere from checkout lines to doctors' offices? In this talk, you will learn how to talk to your phone and have an app on Azure to show your friend 5 minutes later. The basic DevOps tools you already know, plus a little bit of AI magic, are all you need! If you want to follow along, the demo will be in Azure with GitHub Actions and GitHub Copilot, and you can have it set up on your phone by the end of the session. Just come in with an Azure account and a GitHub repo. Join us for pizza, drinks, and networking @ Improving's office. Doors open at 5:45.

One of the most valuable parts of this community is the opportunity to think out loud with other product professionals. This session is built for exactly that. As we wrap up the quarter, it’s a great time to pause and reflect. What’s on track? What needs adjustment? Where could a small shift create bigger impact? Join fellow product professionals for a focused, interactive conversation designed to help you recalibrate for the next quarter. You’ll have the opportunity to share where you are, hear how others are thinking through similar challenges, and gain fresh perspective you can bring back to your team and organization. We’ll gather at 8:00AM, with discussion starting promptly at 8:15AM. 📍 First Watch - 7227 N High St Located in: The Shops at Worthington Ample parking is available. Food and beverages will be available for purchase. Start your morning with clarity and connection — we hope to see you there! ☀️

Let’s meet, wander the exhibits and open galleries, and enjoy an evening out in the Franklinton Arts District. (Nearby pay parking is available in the garage on McDowell, right around the corner from One Line Coffee, and, past it along the curb as McDowell dead ends.)

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!
