Together with Capgemini, we’d like to invite you to our talk in June. This time, we’ll be discussing spec-driven development with Simon Martinelli. **Spec-Driven Development in Practice: How AI Simplify Full-Stack Java** AI is transforming how we develop software, but many teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. What if specifications became the single source of truth instead? This session introduces Spec-Driven Development (SDD) and the AI Unified Process (AIUP), a practical approach in which developers write clear, structured requirements, and AI generates everything else: diagrams, code, and tests. When requirements change, the system stays consistent automatically. Based on a real-world Java project built with Spring Boot, jOOQ, and Vaadin, the most productive and secure web framework for Java, you’ll see how SDD keeps business rules, data access, and UI perfectly aligned. Join this session to learn how AIUP helps Java developers deliver applications faster, with less boilerplate and more focus on what really matters: understanding the domain. Most teams still treat code as the source of truth, leading to outdated documentation and hidden business logic. In this session, you’ll learn how Spec-Driven Development (SDD) and the AI Unified Process (AIUP) let you define requirements once and generate consistent Java code, diagrams, and tests automatically. Based on a real project with Spring Boot, jOOQ, and Vaadin, this talk shows how to build faster, safer, and more maintainable full-stack Java applications. **Simon Martinelli** Simon Martinelli is a Java Champion, Vaadin Champion, and Oracle ACE Pro with over three decades of experience as a software architect, developer, consultant, and trainer. He is the creator of the AI Unified Process (AIUP) and a strong advocate of Spec-Driven Development. As the owner of Martinelli LLC, he coaches teams to get up to speed with AI-driven development. He regularly shares his insights through international conferences, articles, and his blog, Keep IT Simple (https://martinelli.ch), where he writes about AI, architecture, and modern Java development. He is also a lecturer at two universities in Switzerland, where he teaches software architecture, persistence, DevOps, and cloud-native development.

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 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.

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.

**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/). You are very welcome to join!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. 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.
