In March we welcome [Valentin Churavy](https://github.com/vchuravy) to talk about the [Julia frontend](https://julialang.org) for LLVM. Valentin is a long-term contributor to JuliaLang, JuliaGPU and EnzymeAD. He is a Research Software Engineer at [JGU](https://www.uni-mainz.de/) and Uni Augsburg, and graduated from MIT where he did his doctorate in the [JuliaLab](https://julia.mit.edu/). Julia is a high-level dynamic programming language that is widely used in technical computing. Let's explore how Julia uses LLVM to target CPUs, accelerators and even synthesize gradients. 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!

This **coworking and networking** meetup is for neurodivergent people to get our tasks/projects/work done and to connect with other neurodivergent, whether for focus work or just finding someone who understands what you’re working on. **PLEASE READ THE EVENT DESCRIPTION BELOW:** So we can be self-accountable for our own comfort. **Location:** Werkräume inside Humboldt Forum [https://maps.app.goo.gl/Jw5totHbQadfsJsE8](https://maps.app.goo.gl/Jw5totHbQadfsJsE8) The **exact area** of Werkräume where we cowork will be updated in the **pinned comment on the event page**, as it is a public space and we cannot reserve a specific spot. **How to find Werkräume:** * **If you are starting from the Front Desk:** Find the large escalator behind the front desk. Go up to the 1st floor (one level above ground floor). * **If you are starting from the Humboldt Bistro:** go to the other building. Find the escalator and go up to the 1st floor (one level above ground floor). * **Final Destination:** On the 1st floor, look for the Werkräume sign. **What to expect:** * We usually use **[Pomodoro method](https://en.wikipedia.org/wiki/Pomodoro_Technique).** **When you are late** and the session has started, just take a seat and start working until break time. * However, **feel free to work with how you are most comfortable with.** What's important is, we all become accountability buddies. ✨ **Notes:** 1. **This a public place so bring your sensory management tools (earphone, stim toys, etc).** We can´t control the environment if there are other groups having their activities. 2. **The Werkräume can't be reserved** so we will all help each other by occupying the seats. 3. The place has wifi, locker and toilet. 4. The space has power plugs, but only in specific areas. Please ensure your devices are charged before coming. 5. **Food & drink:** there is a Bistro but pricey. Feel free to bring your own. **IMPORTANT:** No eating in the Werkräume. Use the public visitor seating instead. 6. **Bring a coin for the locker.** Security may ask you to store bags in the lockers outside the Werkräume. 7. **PLEASE EDIT YOUR RSVP if you can't come.** This helps us better manage the coworking session. Your update is much appreciated. 8. **All organizers are volunteers who are neurodivergent individuals.** We ask you to **be kind to us** and for your **support in making the event an enjoyable** for everyone. **Till then busy bees!**

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!

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. Currently serving as a Senior Data Migration Specialist at AWS, I architect and execute complex enterprise migration strategies while actively expanding into Generative AI technologies to enhance migration efficiency and optimize data workflows. My core competencies include database architecture, performance optimization, migration planning, and cross-platform data integration, combining decades of hands-on experience with modern cloud methodologies to deliver scalable, reliable data solutions that bridge traditional database principles with emerging AI capabilities. **Kai Wagner** \- I’m Kai\, a Senior Engineering Manager at Percona with almost two decades of "bleeding" open source in my DNA\. From the Linux Kernel and Ceph at SUSE to leading PostgreSQL development today\, my career is built on a foundation of transparent communication and community\-driven innovation\. In my free time\, I'm a handball\, agility and movement coach for various ages and teams\, next to spending time with the family and on the house\. **Note** We will again take notes who signs up and does not show up.

**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.

A small NEXUS gathering built around movement rather than discussion alone. This is for high-bandwidth Mavericks who spend most of their time in conceptual thought and need some physical counterweight. Why bouldering? Because it’s deliberate: short problems, full focus, and immediate feedback. You’re on the wall, solving something tangible. The mental noise drops instantly! Conversations happen naturally in between climbs. No pressure, you move at your own pace. Some exchanges stay light. Others go deep. Both are fine. This is not about athletic achievement. It’s about presence, recalibration, and being around people who don’t require you to shrink or translate yourself. Come as you are. Try some bouldering problems. Rest when needed, and engage where it makes sense. **Bring comfortable clothes and climbing shoes if you have them (rentals are available at the gym).** *Registration equals commitment. If you sign up, you show up. Read the group description first and decide consciously. For context about NEXUS, visit our* ***[website](https://thenexusformula.com)*** *and* ***[newsletter](https://news.thenexusformula.com)****.*

In this hands-on lab, you’ll create an autonomous agent that: * speaks the **A2A protocol** to collaborate with other agents * registers to an agent hub for discovery * connects to an **MCP server** when tools are needed * intelligently chooses ***when to delegate vs when to execute*** No lectures. Just systems thinking + real building. *** ### What We’ll Do * **10:00** \- Quick round of introductions * **10:15** \- Recap: AI Agents\, MCP Protocol and A2A Protocol * **10:30** \- Build your decision\-making agent * **12:00** \- Live demos \+ technical teardown * **12:30** \- Wrap\-up \+ takeaways *** ### What to Expect * Hands-on building, not passive listening * Real agent-to-agent experiments * Collaboration with fellow builders * Fast ideas, quick tests, lots of learning * Unexpected behavior (the fun part) *** ### What Not to Expect * Long lectures * Step-by-step tutorials * Sales pitches * Perfect code This is a **lab**; we learn by building, breaking, and iterating. *** ### ‍ Who Should Join Curious developers, tinkerers, and engineers, with basic knowledge of AI Agents. **Bring:** * Laptop with dev setup * Access to an LLM (Claude / OpenAI / Ollama) * Comfort building small things in any language *** ###

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

Do you want more motivation and confidence to build Lasting Relationships? This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This class is held at the Dianetics and Scientology Life Improvement Center.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
