**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://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)**[ Signal group](https://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)! **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. This time, Flix will walk us through error handling approaches in Rust — from typed error enums to crates like anyhow and thiserror — and present his own take: neuer-error, a single-type error library that captures source locations instead of backtraces and provides typed, discoverable error context without generics soup. Then Raf will show off a fun project that renders canvas primitives with vector and matrix geometry, built from scratch with zero dependencies. If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that! 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). 19 February 2026 is our eleventh meeting. Our next projected meetings are going to occur on the following dates: * 19 Feb 2026 * 19 Mar 2026 * 16 Apr 2026 * 14 May 2026 (tentative, public holiday) * 11 Jun 2026 * 9 Jul 2026 * 6 Aug 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 Berlin Rust Hack and Learn online meetup's [Matrix channel](https://matrix.to/#/!xycQxSjSAvEezkyztA:chat.berline.rs). You are very welcome to join!

In this Yin practice, we take time to pause, soften, and simply be. With the support of long-held, floor-based postures, the body gradually opens, accessing the deeper layers of fascia and energy pathways. We allow gravity to guide the process. This subtle work calms the nervous system, nurtures stillness, and encourages quiet reflection. It's an opportunity to release tension from both body and mind, and to reconnect with yourself on a deeper level. The class is led in English and is open to all levels. .

Join us for the next Spring User Group Berlin meetup! This time, we are bridging the gap between rock-solid operations and developer joy. **Talk 1: Secure and Seamless: Injecting Kubernetes Secrets into Spring Applications** *Speaker: Dmitriy Goi, Deutsche Bank* Look, we’ve all done it. You need a database password, so you throw it into an environment variable and call it a day. It works, it’s fast, and your app starts up. But then the security audit hits, or your credentials rotate and suddenly your logs are full of connection errors because your Spring context is stuck in the past. At Deutsche Bank, "good enough" usually isn't. I’ve spent the last few years moving Spring apps into Kubernetes and realizing that most tutorials lie to you. They show you the easy way, not the way that survives in production. I’m going to show you why environment variables are a security trap and how mounting secrets as files actually works (and where it breaks). We’ll get into the mess of secret rotation, why you probably need a CSI driver or an External Secret operator, and how to make Spring Boot actually pick up those changes without a manual restart. **About the speaker:** A passionate software engineer at Deutsche Bank, Dmitriy brings 8 years of development experience to his focus on modernizing application development. He specializes in Spring Boot and Kubernetes and is currently helping lead the charge on migrating key applications to a hybrid cloud environment, emphasizing secure and efficient engineering practices. \-\-\- **Talk 2: Adopting Kotlin for Spring 7: Cleaner Code, Fewer Bugs, Some Tradeoffs** *Speaker: Daniil Tsarev, JetBrains* Kotlin is becoming a first-class citizen in the Spring ecosystem, especially with the latest features in Spring 7. In this talk, we'll explore how easy it is to adopt Kotlin in existing Spring projects, what tangible benefits it brings to everyday development, and where some edges still are. Expect practical examples, real-world tradeoffs, and an honest look at whether Kotlin is the right choice for your Spring stack. **About the speaker:** Daniil Tsarev is a Software Developer at JetBrains with over 10 years of experience working with the Spring ecosystem. Previously was developing a Spring-based full-stack framework for enterprise solutions. Now passionate about developer productivity, he’s dedicated to creating tools and solutions that make developers’ lives easier. **📅 Agenda** [**18:30**]: Doors open, food, drinks & networking [**19:00**]: Talk 1: Secure and Seamless (K8s Secrets) [**19:45**]: Short break [**20:00**]: Talk 2: Adopting Kotlin for Spring 7 [**21:00**]: Q&A and more networking [**22:00**]: Closing the doors Come for the knowledge, stay for the community.

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** \- Tracking \(Protection\) Everywhere There are a variety of tracking vectors on the web. But how exactly does this tracking work and what mechanism do we have available to protect our privacy? This talk takes a closer look at the many anti-tracking mechanisms Firefox uses to protect its users, and discusses the threat models behind them and the practical protection they provide. Bio: Manuel Bucher is a software engineer on the Firefox Privacy team working on anti-tracking in Firefox **19:30:** No Servers, No APIs: AI in the Browser I’ll present how modern web technologies make it possible to run AI models directly in the browser combining WebLLM and WebAssembly to deliver powerful, privacy-preserving client-side AI experiences. For more context, here’s a related article I wrote for Mozilla AI: [https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/](https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/) **Bio:** Barış Güler is an engineering leader working on in-browser AI systems that leverage WebLLM, WASM, and web platform features to bring AI inference and tooling into client environments. He writes about web-native AI and open-source approaches to privacy-first machine intelligence (and a Rust fan, for sure).

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. (NOTICE - Location change!) This session will be at the Karl Road Branch of the Columbus Library in the Conference Room 2.

**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** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
