On the 3rd March we will host the next iteration of our monthly Audio Developer Meetup. The long talk will be by Christian Grothe on building audio applications for the terminal in rust. The short talk will be by Maksymilian Padalak on how to convert text prompts into plug-ins. See below! As always, there will be a chance to network over drinks and pizza. Anyone interested in Audio development is welcome! Doors open at 18:00, talks start at 18:15. Please note: Attendance is **strictly limited** to people who have RSVP'd Talk details: **Building Audio Applications with a TUI in Rust** \- Christian Grothe In this talk, we will explore the possibilities of building musical instruments with a terminal user interface using Rust and Ratatui. We will look at both the challenges and advantages of this approach, illustrated with practical examples and sound demonstrations. **Christian Grothe** is a programmer and musician based in Potsdam. During his music studies, he became increasingly interested in creating improvised electronic music using his own tools. Starting with MAX/MSP, exploring the Axoloti board, experimenting with Arduino and Teensy, and eventually building an analog modular synthesizer from scratch, his technical abilities evolved through time and hands-on experience. Primarily focused on building tools for live sampling, Christian settled on a stack where he uses Rust to create custom sampler instruments running in the terminal, alongside SuperCollider patches—literally making music with tmux. **pluginmaker.ai - How We Turn Text Prompts into Working VST/AU Plugins -** Maksymilian Padalak pluginmaker.ai is the first ever browser-based, no-code generator for VST and AU audio plugins. Users describe an effect or instrument in plain language - "plate reverb with decay and damping controls" - and within minutes receive a plugin they can load in almost any DAW. In this talk they'll demo the full flow from prompt to plugin, walk through how the generation pipeline works at a high level, and share what they've learned building an AI system that writes real-time audio code. Maksymilian Padalak is an ex-Nord Security (NordVPN) developer, guitarist, music producer, former professional standup comedian, and co-founder of pluginmaker.ai - an AI-powered platform that generates audio plugins from natural language descriptions. He co-founded the project with his best friend and ex high school bandmate Dominik Bilski, an ex-FedEx and ex-Pearson developer, bassist, and AI enthusiast. Both quit their jobs to build pluginmaker.ai full-time.

Hi! Welcome to Thought Experiments in Pubs - Berlin edition, where you get to have deep conversations with people you've never met. The topic will be confidence. I'll post some questions that will help guide us through the topic as a comment on the day. **Location:** [Atopia Kaffeehaus, Prenzlauer Allee 187, 10405 Berlin](https://maps.app.goo.gl/Ukuup9CTrmedrB6f9) * Please consider that the locations we visit do not charge us for our booking, so in return, please make sure to show your appreciation by buying drinks or snacks. * If you're signed up but can't make the event, please cancel so someone else can take your spot * Make sure you check the right address, there is a sister pub nearby and it's not that one ☝️ **The idea:** A chance to meet and talk at a 'deeper' level, and skip the 'small talk'. **How will it work?** We will have a set of 'Thought Experiments', short, philosophical scenarios and questions, which will be discussed in groups. The conversation will flow freely, there are no strict rules, simply share and discuss your perspectives on the given topic. The thought experiments will be posted here ahead of the event. **Who should come?** Everyone! We believe that the more perspectives, the richer the conversation. This group is not about being experts in philosophy, it is about *doing* philosophy. That is, bringing our various life experiences and lenses on the world to group discussions about the human experience, the nature of reality... etc. **Do I need to bring anything?** No! Just an open, inquisitive mind. We will do 3 rounds of discussions. After the event, I would love to hear your feedback on the session. The thought experiments we will discuss are around the theme of the day. Prompts will be posted here on the day of the event. See you soon! \- Dirk *Thought Experiments in Pubs Berlin is inspired by [Thought Experiments in Pubs London](https://www.meetup.com/thought-experiments-in-pubs/), which originated in 2023 as a social experiment to get people together to connect at a deeper level.

Liebe JUG-Mitglieder, wir möchten Euch herzlich zu unserem nächsten Stammtisch, der jeden ersten Dienstag im Monat stattfindet, einladen. Alles weitere kann im unserem Blog unter http://www.jug-berlin-brandenburg.de/ gefunden werden. Viele Grüße Sandra, Jan, Jörg und Oliver

**\*\*\* SIGN-UP on LUMA ONLY to get the address and attend!\*\*\*** **A Small Update for 2026** Thanks to those who took the LSLab survey. We learned a lot, and will use that feedback to continue creating a dynamic, safe and relevant learning community. Starting now, there will be a few small changes, beginning with this meet-up, so we can test as we go. So after many years on Meetup, LSLab Berlin is evolving. **From now on:** * Events will be announced inside Meetup, but *organized on LUMA* (**Link to sign up here:** [https://luma.com/vs42c5uc](https://luma.com/vs42c5uc)). * We’ll charge a small participation \*fee when you sign up. * Sign-ups to the email so updates can come from LUMA - no spam, just updates on LS events (address or date change, opportunities to be on the design team, events relevant for LS!) This helps: * Cover admin and multiple platform costs * Support behind-the-scenes coordination * Encourage attendance commitment * Give our hosts a more accurate guest count It’s about sustainability and respecting everyone’s time. We will see how it all works and make adjustments as we go. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* **Here we come, Deutsche Bahn** 🚆 We’re on fire in 2026, our second Lab this year and we’re not even out of Q1. As always, we are looking to make it: fun, practical, slightly surprising. **Theme:** TBD – our design team meets next week and we’ll post the theme and string as soon as it’s ready. **Our Host:** We’re excited to be hosted by Deutsche Bahn. Their space gives us plenty of room to move, work in small groups, and play. **What Happens at an LSLab?** Every Lab includes: ✔️ Networking & connecting ✔️ Giving and Getting Help ✔️ A thoughtfully designed Liberating Structures “string.” ✔️ Action planning We don’t do long debriefs during the session, on purpose. LSLab is a practice space, mostly for the Design Team, and the participant, you, learn by doing! By participating. By seeing what it’s like to be part of the collective intelligence. Questions are welcome during the break and after we close. **New to Liberating Structures?** Totally fine. You don’t need experience. We’re a mix of beginners, experienced facilitators, agilists, OD/L&D folks, coaches, leaders, and curious humans who want better collaboration. You’ll learn by being part of it. **Language** Intro and instructions are in English. Small group work can happen in whatever language works for you. Mark your calendar. Come practice. Bring your curiosity. See you there, Sylvia \*If you are facing financial hardship or have been laid off, we'll waive your fee. Just reach out to us and let us know.

Welcome to the very first meetup of our new community! As we mentioned in our group description, the way we build and deliver software is evolving rapidly. We are kicking things off by bringing together Berlin’s engineers, architects, and tech leaders to discuss the shift from standard automation to **Agentic AI** and **intelligent cloud workflows.** For this premiere event, we are currently finalizing a lineup of two deep-dive talks that will explore practical use cases in this emerging field. We will update this page with the specific speaker details and talk titles very soon—stay tuned! **What to expect:** * **Insightful Talks:** Real-world perspectives on where software delivery is heading (Speaker below) * **No Fluff:** We’re here to move beyond the buzzwords and discuss what actually works. * **Great Company:** Plenty of time to grab a cold drink, enjoy some snacks, and connect with peers who are facing the same challenges and opportunities in the cloud-native space. **Speaker:** Milan Wiezorek – Head of Customer Engineering, Google Cloud ([https://www.linkedin.com/in/milanwiezorek/](https://www.linkedin.com/in/milanwiezorek/ "https://www.linkedin.com/in/milanwiezorek/")) **Talk:** "Operating Agentic Eco-Systems at Scale" Milan helps government and healthcare institutions harness secure, resilient AI to solve society's biggest challenges. He previously led AI industrialization for the German automotive industry – spearheading the Gemini-powered Mercedes-Benz 2026 CLA launch, scaling workflow automation for Bosch, and accelerating R&D for Volkswagen through AI surrogate modeling. **Speaker:** Ahmed Diab – Consultant Cloud Engineering (https://www.linkedin.com/in/ahmed-diab-ac/) **Talk:** "Pioneering the Future of Agentic DevOps: Why Mindset Matters More Than Tools" Ahmed is a DevOps and cloud engineer working with modern automation and AI-assisted tooling in production environments. He focuses on how agentic systems are applied in practice, where they help, and where careful choices are needed when adopting new tools in DevOps workflows. Whether you are already experimenting with AI agents in your pipeline or just want to understand what the hype is about, you’ll feel right at home.

**Fellow Humans, we're starting a book club!** We focus on understanding what's actually happening on the crowded stage of AI: the companies driving the AI race, the decisions being made on our behalf, and what it all means for the rest of us. Every few weeks, we'll choose and read one book together and talk about it. Bring your **thoughts**, your **questions**, your **highlighted passages**, and your **honest reactions**. **Our first pick: *Empire of AI* by Karen Hao**, who has worked for The Wall Street Journal and contributes to The Atlantic. *She argues that the pursuit of an artificial superintelligence has become its own figurative paper clip factory, devouring too much energy, minerals and human labour. She portrays OpenAI and other companies that make up the fast‑growing A.I. sector as a “modern-day colonial world order.”* (excerpt from the NYT review) **What to expect:** A relaxed, semi-structured conversation (around 2 hours). We'll dig into the themes together, share what stood out, and connect the ideas to what we're actually experiencing. **No expertise required, just read the book and show up curious.** **Why a book club?** Because some things can't be captured in a headline or a 60-second video. The questions AI raises for our work, our relationships, and our futures deserve more than a scroll. They deserve a real conversation with real people, and a book gives us common ground to start from. **After this first Meetup, you help define what's next!** Suggest books that have changed how you think about AI, technology, or what it means to be Human. This is your club. **No tech background needed. Just curiosity and willingness to think out loud with fellow critical thinkers.** **Join our [LinkedIn Group](https://www.linkedin.com/groups/10088542/) and [Substack](https://humanfuturehub.substack.com/)** for articles, perspectives, and resources between events. See you there, Your HFH Team! **Humans, together. Nobody is left behind.** ❤️

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.

After years in traditional IT, where he regularly had to work night shifts due to emergencies, he decided to do things better—for customers and for IT professionals. Today, he help SMEs transform their IT from a constant work in progress to a reliable infrastructure they can depend on. **Jonathan\`s talk: "How we are completely rethinking system administration as a service for your company"** Companies cannot possibly do everything themselves. So things like accounting, logistics, and IT are outsourced to external service providers. In the IT sector, system houses have been doing very well for themselves in recent decades! Every little thing is charged for, and if there are any errors, the customer is expected to open a ticket. We are rethinking this! We are applying the “as-a-service” concept from Airbnb, Uber, and Everstox to system administration and taking responsibility. Jonathan will show how this works in his talk. ​ **Speaker 2 @March 12** **[Anne Biedermann](https://www.linkedin.com/in/anne-biedermann/), independent wealth partner for women** Anne has extensive experience across venture capital, single-family-office & HNWI investing, and early-stage operations. She works with investors who are building, inheriting, or stewarding wealth on how to allocate capital with clarity — particularly where venture capital intersects with long-term wealth strategy. Anne also invests personally, giving her a practitioner’s perspective on capital allocation decisions. **Anna\`s talk: "Not All Capital Is the Same: Decoding Investor Behavior"** Founders often assume all investors evaluate risk, timelines, and returns the same way and that assumption is costly. This session breaks down how funds, family offices, and individual investors actually make decisions, where founder–investor misalignment typically begins, and how founders can better position themselves for the right kind of capital, not just any capital. **Speaker 3 @March 19** **[Immo Ait Stapelfeld](https://www.linkedin.com/in/immoaitstapelfeld/), Co-Founder & CEO at [913.ai](https://913.ai)** **"From Legal Complexity to Practical AI. How We Help Regulated Industries Use AI Without Losing Control"** This presentation tells the story of Immo’s transition from a trained lawyer working in mass proceedings to an entrepreneur building AI products for regulated industries. His legal background, combined with hands-on experience as a founder, shaped a pragmatic view on AI. not as a disruptive replacement, but as a controlled and compliant tool. At[ ](http://913.ai)[913.ai](https://913.ai), this perspective enables conservative organizations such as insurers to enter the AI era in a way that respects regulation, responsibility, and existing teams while still unlocking real efficiency gains. ​ **The series at a glance** [12min.me](http://12min.me/) STARTUP consists of three independent sessions.

Projects that are over budget, delayed, or that fail to scale past the POC phase are very common. In many of these scenarios, choosing the right approach can be as critical as the solution itself. Should you build a tailored machine learning model, leverage the power of large language models (LLMs), or integrate with AI copilots? Each option has unique strengths, trade-offs, and resource requirements, and the key to success lies in aligning your choice with your business goals and technical constraints. In this talk, we will go beyond the basic concepts and definitions to provide a practical guide that allows attendees to navigate these decisions through real-world case studies. We will examine scenarios in which different AI paradigms were chosen, discuss the factors that influenced those decisions, and outline the process for evaluating needs, constraints, and outcomes. From assessing data availability and team expertise to balancing cost and scalability, you'll gain insights into the critical considerations that guide the selection process. By the end of this session, you’ll have a clear process for determining whether machine learning, LLMs, or copilots are best suited to your AI challenges and understand the resources and strategies needed to bring your chosen solution to life. This talk is ideal for decision-makers, technical leads, and innovators seeking to demystify AI implementation and maximize the impact of their investments.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
