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.

There's a new Clojure documentary. I haven't seen it yet. I'm pretty sure it's great. Let's watch it together! Organized by nikitonsky https://mastodon.online/@nikitonsky/116680737385288302

This class is a grounding yet energizing practice that blends the calm control of Slow Flow with the strength and rhythm of Power Flow. **What to Expect:** * **Slow Flow** – Begin with steady, breath-guided movements to build awareness, refine alignment, and create a strong foundation. * **Power Flow** – Transition into dynamic, strength-focused sequences that raise the heart rate, build heat, and develop endurance and confidence. * **Cool Down & Relaxation** – Finish with deep stretches and soothing breathwork to release tension and restore balance. https://www.eversports.de/org/activity/4e0f4c1b-c06d-49b6-9d1f-dd4c3fab5b7b

What happens when PMs stop watching engineers code — and start shipping themselves? You’ve probably heard the stories. Maybe you’ve already tried it in your own company. AI is changing how product teams build, collaborate, and ship — fast. Join us for an evening with product leaders sharing real-world experience building and shipping customer-facing features with AI, not just internal demos and experiments. We’ll talk about PMs opening PRs, non-devs contributing directly to production, and what actually changes when the whole team gets closer to the codebase. This event is designed for Product Managers and Product Leaders who want to understand how product roles, collaboration, and development processes are evolving in the AI era. **Agenda** 18:15 – Doors open for snacks, drinks, and networking 19:00 – Welcome from ProductTank Berlin 19:10 – Opening the PR is just the beginning, Dmitry Gorshkov 19:40 – What happened when we let non-devs into the codebase, Elena Berendeeva 20:10 – Networking 21:30 – Event ends Please note: - Please bring your IDs as you’ll need it when entering the venue. - The event is RSVP only: to enter, you must RSVP here on Meetup. - We'd like to capture the event with photographs for promotional purposes, such as sharing on LinkedIn after the event. If you have any concerns or preferences regarding this, please feel free to let us know beforehand. **Opening the PR is just the beginning** Dmitry will show how to go deep into the codebase as a PM and make it worth the effort. Crafting code is time consuming, so should PMs code instead of doing PM work? Absolutely. But you must come prepared. About the speaker [Dmitry Gorshkov](https://www.linkedin.com/in/dmitrygorshkov?utm_source=share_via&utm_content=profile&utm_medium=member_android) is a lead product manager at Finom, a Dutch fintech superapp for small businesses. Dmitry has shipped successful products at N26, Taxfix and Cut the Rope, among others - and has more than a decade of product management experience. **What happened when we let non-devs into the codebase** A year ago, we let PMs, designers, and QA contribute directly to our existing codebase using AI. What followed wasn’t just faster shipping – it was a quiet shift in how our team made decisions, handled ownership, and thought about their roles. This is that story. About the speaker [Elena Berendeeva](https://www.linkedin.com/in/berendeeva-elena?utm_source=share_via&utm_content=profile&utm_medium=member_android) is a PM at JetBrains who spent the last few years building 0-to-1 products – through pivots, sunsets, and a lot of uncertainty. Her most recent product is Matter, an AI prototyping tool that her team – designers, QA, and engineers – used to ship directly to production. She explores AI-native workflows and the evolving role of PMs in agentic product development.

Bringing you back to your original harmonious state by releasing stress and emotions acquired in your body with our overwhelming lifestyles in current times. We achieve this positive state with the practice of Yin yoga inducing static stretches working on fascia and inner tissues and staying in a meditative state. Combining our practice with the healing vibrations of Himalayan singing bowls allows us to reach a greater state of tranquility and well-being. This class is suitable for every yoga practitioner and is low in intensity. https://www.eversports.de/org/activity/1b4ab2e6-e572-4a64-8ac4-32cd851651be

Hello fellow Symfonians, we are thrilled to announce something we've never done before: a **Live Code Review** session! This time it's not about slides and talks – it's about your code. Submit a snippet beforehand and we'll review it together as a group, live on stage. Expect honest feedback, fresh perspectives, and plenty of "ah, that's how you could do it" moments. This time we are hosted by **c-base** (Rungestrasse 20 10179 Berlin). Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers. **Agenda:** 18:30: Doors open 19:00: Welcome and Introduction 19:20: **Part 1: "Live Code Review - Bring Your Own Code"** **by Stefan Priebsch & Sebastian Bergmann** 19:50: Break & Snack 20:00: **Part 2: "Live Code Review - Bring Your Own Code"** **by Stefan Priebsch & Sebastian Bergmann** 20:40: Socializing **Event Details:** **"Live Code Review - Bring Your Own Code"** by Stefan Priebsch & Sebastian Bergmann When Sebastian Bergmann and Stefan Priebsch take the stage together, expect an evening focused not on theory, but on the craft of building good software. As founders of [thePHP.cc,](http://thePHP.cc,) they have influenced the conversation around code quality, testability, refactoring, and sustainable architecture in the PHP community for many years. At this Symfony User Group meeting, they bring that experience to a special format: a public code review of code submitted by attendees. Together, they will look at real-world examples from everyday development, share direct feedback on structure, readability, testability, and maintainability, and show how even long-lived codebases can be improved step by step. This is a great opportunity to see how experienced practitioners approach code, which common issues they spot quickly, and which improvements can have the biggest impact in practice. If you would like feedback on your own code, bring it along. Please make sure to remove any credentials or personal data before sharing it publicly. The feedback will be constructive, respectful, and focused entirely on improving the code. Don't miss this insightful event, engaging discussions, and networking opportunities. We can't wait to see you at the June Symfony User Group! If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!

**Deutsch** Schnapp dir deine Stricknadeln, dein aktuelles Projekt und strick mit uns! 🍻🧶 Wir treffen uns Samstags gemütlich in einem Pub – perfekt für alle, die gerne in netter Gesellschaft stricken. Alle sind willkommen, vom absoluten Anfänger bis zum Profi. Es handelt sich hier aber nicht um einen Kurs. Im Vordergrund stehen Plaudern, Lachen und gemeinsames Stricken. Bring dein Strickzeug mit, bestell dir gerne ein Getränk und genieße einen entspannten Abend mit Handarbeit und netten Gesprächen. Egal, ob du an deinem Projekt weiterarbeiten oder einfach nur die Atmosphäre genießen möchtest – du bist herzlich willkommen! **English** Grab your needles, your current project, and come knit with us 🍻🧶 This is a relaxed Saturday social knitting meetup in a local pub—perfect for anyone who enjoys knitting in good company. All skill levels are welcome, from absolute beginners to seasoned pros, but this isn’t a teaching workshop. Think more chatting, laughing, and stitching together than structured instruction. Bring along your own knitting materials, order a drink if you like, and settle in for an easygoing evening of craft and conversation. Whether you want to make progress on a project or just enjoy the vibe, you’re very welcome here.

Save the date! The Mozilla Meetup series continues with talks focused on modern web technologies. To account for typical **no-show rates**, we’ve opened more RSVP spots than we can physically accommodate. Based on our last event, only about 36 of 100 registered participants (including Mozillians) attended in person. **We will admit attendees on a first-come, first-served basis and will need to close the doors once we reach room capacity (around 50 people).** Note that this event operates under the [Mozilla Community Participation Guidelines](https://www.mozilla.org/about/governance/policies/participation/). **18:00 - Doors open** **18:30 - Keep Off My LAN: Firefox's Implementation of Local Network Access** In June 2025, researchers exposed Local Mess — a tracking vulnerability where Meta Pixel and Yandex Metrica scripts abused localhost access to silently track millions of Android users across the web. The web platform had a long-standing hole, and Firefox moved quickly to help close it. This talk presents Local Network Access (LNA), the emerging standard that finally tackles these threats along with a backlog of security vulnerabilities tied to localhost and local network devices. It walks through the specification, Firefox's implementation, and the real-world deployment challenges encountered along the way and how they were mitigated. Beyond the "what," this talk opens up a conversation. As LNA is still taking shape in the WICG, it's a chance for people building in the local network and localhost space — and for the adblocker and anti-tracking community, especially those running DNS-based blockers (Pi-hole, AdGuard Home, and similar) — to surface edge cases, breakage, and threat models that should be designed for. Anyone running services on localhost / local network, or operating local DNS-based tracking protection, is invited to share what LNA needs to get right. About the speaker: Sunil Mayya is a software engineer on Mozilla's Firefox Networking team, based in Nuremberg, and a core contributor to Firefox's implementation of the Local Network Access standard. **19:30 - The Devil is in the Defaults - what to do about XSS** This session is about latest defenses against Cross-Site Scritping (XSS), the most prevalent security issue of all times. We will showcase typical XSS bugs and how they can be avoided. We will also explain why previous mechanisms fall short of protecting web sites at scale and why we believe Trusted Types and the Sanitizer API can help closing this gap. The presentation will also give hands-on advice to enable security and development teams adopting these new protections. We will close with a bit on security considerations and remaining risks. About the speaker: Frederik Braun is a security engineer and manager working on Firefox.

This trip costs 289€ including - * Travel with ICE (to and from) * 4D/3N Accommodation * Rodelbahn tickets * Entry to select attractions as per itinerary * Guided Hikes Check memories from our past trips here - https://tripstotales.com/memories Some weekends are meant to disconnect — this is one of them. The Black Forest is where nature slows everything down. Think dense forests, quiet lakes, flowing waterfalls, and roads that lead you deeper into calm, scenic landscapes. Over these 4 days, the experience is built around enjoying this rhythm — from peaceful walks through forest trails to discovering hidden waterfalls and soaking in views that feel untouched and timeless. There’s also a fun side to it — like the Rodelbahn ride, adding a bit of thrill to the otherwise slow-paced escape. And in between, you’ll explore charming towns like Freiburg and Staufen, where cobbled streets and local cafés bring a different kind of experience. This trip is not about rushing from one place to another. It’s about taking a step back, breathing in fresh air, and enjoying a long weekend that feels calm, scenic, and easy. If you’re looking for a nature-filled getaway with a mix of relaxation, light adventure, and beautiful landscapes, this is exactly that. Why travel with TripstoTales? At TripstoTales, we focus on curated small-group trips that are thoughtfully designed from start to finish. We handle the planning, routes, and logistics so that the experience feels smooth and stress-free. Our trips are built for people who want more than just visiting places. With a smaller group size, everything feels more personal, more relaxed, and far from the typical rushed group travel experience. For this trip, that means a well-paced long weekend where you can fully enjoy the Black Forest — without worrying about planning, transport, or missing out on the best spots. If you’re looking for an easy, scenic escape with great company and everything taken care of, TripstoTales is the right way to do it.

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. With the [introduction](https://berline.rs/2026/04/01/berlin-talks.html) of the new [Rust Berlin Talks](https://berline.rs/about#rust-berlin-talks) meetup series, **[Rust Berlin on location 🏳️‍🌈](https://berline.rs/about#rust-berlin-on-location)** strengthens its focus on social community experience, the exchange of knowledge, ideas and perspectives, and the joy of spontaneity. This time, Florian Gilcher will give a small **workshop on structured and safe usage of *\`unsafe\`***. We will look at some common use-cases and how common hazards can be avoided. Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 11 June 2026 is our fourteenth meeting Our next projected meetings are going to occur on the following dates: * 9 Jul 2026 * 6 Aug 2026 * 3 Sep 2026 * 1 Oct 2026 * 29 Oct 2026 * 26 Nov 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the **[Rust Berlin on location 🏳️‍🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/).

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. 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. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

A session on using Claude Code, Anthropic's AI coding agent, in real Unity development. We'll cover what coding agents are, where Claude Code fits, and how to apply it to an actual game project. The format is presentation-style, with live demos and time for questions throughout. After brief scene-setting on coding agents and what makes Claude Code distinct, we'll go problem-driven: demoing it live on a released Unity game and introducing each feature as a solution to a problem we hit. What to Expect: * An intro to coding agents and where Claude Code fits * A live demo on a real Unity project * Key features as solutions to real problems: 𝖢𝖫𝖠𝖴𝖣𝖤.𝗆𝖽, context management, hooks, skills, subagents, and MCP * Unity-specific pain points, including Domain Reload and MCP caveats * Putting it together All experience levels welcome. Food and drinks provided. *Note: meetup topics may change — check back for the latest details.*
