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Java** AI is transforming how we develop software, but many teams still treat code as the source of truth, leading to outdated documentation and hidden business logic.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 Most teams still treat code as the source of truth, leading to outdated documentation and hidden business logic.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.

In diesem Kurs beschäftigen wir uns mit verschiedenen Texten aus unterschiedlichen Bereichen. Das können u.a. kurze Geschichten, Gedichte, Zeitungsartikel, Kolumnen oder Videos sein. Immer sind es Themen, die uns gefallen, die wir besonders interessant, wichtig oder manchmal auch richtig schlecht finden. Gemeinsam versuchen wir die Position der Autor*in, den Stil und die Argumentationsstruktur zu verstehen. Dazu diskutieren wir über das, was wir verstehen, welche Meinung wir zu dem Thema haben oder welche Fragen offen bleiben.
Gerne könnt ihr uns auch Themenvorschläge mitbringen oder zuschicken.
Der Kurs richtet sich an interessierte Menschen mit einem B2-Niveau (oder so ähnlich), die Lust haben sich weiter mit der deutschen Sprache zu beschäftigen und ihren Wortschatz zu erweitern.
Die Termine sind sporadisch.

👋 Hallo und 💜-lich Willkommen to the Elixir Berlin Meetup. After a break because all of the bank holidays in May, we are back with the **"happy b10000 birthday, bitcrowd"** edition, since its 16 years when bitcrowd was founded. There's gonna be some modest celebration and some great talks. There is even one free slot still available! If you're new to the community the best way to introduce yourself is [to submit a talk](https://github.com/elixir-berlin/planning/issues/new?template=talk.yml) ⏰ Schedule 18:45: Doors open 19:05: Welcome & Announcements 19:15: 🗣 "Famous last words: Let's build a custom solution" by Agathe 19:45: 🍺 break 🍵🧃 20:15: 🗣 TBA 20:45: ⚡️ Lightning talks and socializing, and a bit of celebration We want to encourage members of the Elixir community to share what they're working on. If you want to give a lightning talk at this Meetup, contact one of the organizers with a short description of your talk - or [submit a talk](https://github.com/elixir-berlin/planning/issues/new?template=talk.yml) See you all there 💜💜💜

This is a 3 phase meetup. You can come at any time. 1.) 6:30 - 7:00 p.m.: Gathering at the meeting spot (see link and photo!). 2.) 7:00 - 7:30 p.m.: Walk & Talk through Tiergarten. 3.) 7:30 - 10:00 p.m.: Immerse conversations in the Zollpackhof beer garden (reserved tables for the meetup). **1.) Meeting spot is Henriette Herz Park.** Copy the coordinates into your maps app: **52°30'38.9"N 13°22'24.1"E** The exact meeting spot can also be seen in the photo. Look for a meetup sign or organizer wearing a black or red lanyard with "staff" written on it. **Best ways to get there:** 1\. S\-Bahn: Get off at Potsdamer Platz by S1, S2 or S25 and walk to the designated meeting spot. 2\. U\-Bahn \(subway\): Alternatively you can get off at Potsdamer Platz by U2 and just walk 5 min straight to the park. 3\. Bus: If you change at mainstation you can take the M41 or M85 to S Potsdamer Platz /Voßstr. and walk to the park. **2.) Walk & Talk through Tiergarten** (the best part imho). During these weird times it essential to connect with nature and like minded people. You will feel instantly energized and an inner calmness afterwards. **3.) How to the find the Zollpackhof beer garden:** https://goo.gl/maps/vDYYaJcFvTmd7hei7 Elisabeth-Abegg-Straße 1, 10557 Berlin We will be sitting outside. Click the gmaps link with the exact meeting spot if you can can't find us! If you enter from the Magnus-Hirschfeld-Ufer, just go to the left part of the beer garden where the self-service is. If you enter from Elisabeth-Abegg-Str, enter the beer garden from the right. *Who is this meetup for:* 1\. Internationals who want to practice German or any other language\. 2\. Germans who want to improve their language skills\. 3\. Anyone who is interested in cultural exchange and wants to socialize\. *What you can expect:* 1\. A professionally organized meetup that can adapt to any changes given the current situation\. 2\. A Walk & Talk to break the ice\. 3\. A collaborating venue where you can further socialize with other members\. *important:* This event is at the same time and meeting location like the "Asian Languages & Culture Exchange 日本語, 한국어, 汉语" one. So I'm basically organizing 2 events at the same time which means that you can expect way more people than on the list. *** Whenever you attend a meetup, the most common as well as first question you get is: "Where are you from?" You probably heard this question a million times. Well, at least I did. From my own experience of attending over 200 international meetups in various countries such as Germany, Japan, Australia and Thailand, I can tell you that asking for the name is a better approach. “A person’s name is to that person, the sweetest, most important sound in any language.” - Dale Carnegie If you really want to connect with like-minded people you should remember their name, but you don't have to remember every persons name you've talked you. Be picky about that, don't be me who can somehow remember everyones name easily. Don't tell yourself sth. like "I'm bad at remembering names." It's all about developing the habit of asking for a name and keep the conversation going on. Furthermore, you want to learn German or any other language. Learning the local language is crucial to connect with the locals and developing a true friendship. This can be accomplished with immersion. My goal is to inspire you to go out of your comfort zone and improve yourself each time you join this meetup.

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!

**Flutter Berlin Meetup — we're back! 🎉** We're back with a new meetup, and this time **Here Technologies** is hosting us — huge thanks for the venue! Two talks on the lineup, covering two very different but equally hot corners of Flutter: automotive navigation and on-device AI. 🕕 **Starts at 6:00 PM** 📍 **Here Technologies office, Berlin** *** **🚗 Talk 1 — Itai Shalom** *Lead Software Engineer @ Here Technologies* **Building a Navigation App in Flutter: Map Rendering on Android & Android Auto** How do you build a full navigation app in Flutter — with the map rendered on Android and running on Android Auto? Itai dives into how the Here team leverages Flutter for this and what makes their app unique. *** **🤖 Talk 2 — Ioannis Gerardis** *Software Engineer · Flutter Dev · AI Dev* **A Flutter App Powered by Local AI: From Synthetic Data (n8n) to Apple Silicon Fine-Tuning (MLX, Gemma)** On-device AI for emergencies. The full journey — from generating synthetic data with n8n to LoRA fine-tuning on Apple Silicon. Stack: **Gemma 4 E2B · MLX · n8n Synthetic Data · LoRA Adapters**. If you're curious about running and fine-tuning models right on the device, this one's for you. *** Expect plenty of technical depth, good conversation, and of course some networking. Come hang out! 🍕 See you there, *Flutter Berlin Community*

**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
