**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, our main topic is going to be dependency-tree security. Jan-Erik will share insights into how security is upheld at Mozilla — in the Firefox project — in the context of third party open source library packages and repeated attempts at attacks through malicious crates. 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). 22 January 2026 is our tenth 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 * 11 Jun 2026 * 9 Jul 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!

**Tired of awkward Zoom mixers and loud Berlin bars?** Join us for a new kind of social experiment. We are hosting a **synchronized online networking sprint** specifically for Berlin's founders, creatives, expats, and techies. **What is it?** This is a 60-minute "Speed Connection" session hosted on **Same**, a new web-app that matches you based on your actual interests, not just your job title. **How it works (The Friday Drop):** 1. **RSVP here** to let us know you're coming. 2. **Join the Session:** At **19:00 CET on Friday**, everyone logs into the app (link provided upon RSVP). 3. **The Magic:** You don't search for people.

The app gives you conversation starters based on what you have in common. **📍 Location:** Online (Link will be sent to attendees). **Price:** Free for early adopters. **Note:** This is a live, synchronized event. Please only RSVP if you intend to be online at 19:00 CET this Friday!

**📅 Week 1 Focus: Kickoff & New Shared Project Theme** We’re starting a new **7-week cycle** with a clear theme: **building one data science project together from start to finish.** 👩‍💻 No experience required Each 7-week cycle focuses on a **small, well-defined part of a larger system**—and over time, these cycles build toward a complete, real-world project (covering data engineering, data science, and deployment). You’re welcome to work on your own project if you prefer, but the shared project gives everyone a common foundation and learning rhythm. 🧠 2026 First Project This cycle’s shared project is an **image-based knowledge extraction system**., including: * Taking photos of book pages or documents * Extracting and cleaning text from images * Structuring that information into something useful (e.g. flashcards, notes, summaries) 📌 By the End of a Full Cycle, You should Have 🎯 A working project in your own GitHub repo 🎯 A small but real portfolio piece you can demo or write about 🎯 Experience going from messy inputs → concrete outcomes Perfection isn’t the goal—finishing something real is. ✨ Who’s Hosting? I’m Lindsey, a senior data scientist working on AI, causal inference, and data products. I’ve built models for fraud detection, uplift modeling, and LLM-based systems—and I care a lot about learning through building, not hype. 📅 When: Saturday, Jan 24 · 9:30–11:30 📍 Where: Torstraße 59, Forward Earth 💻 Bring: Your laptop, an idea—or just curiosity
