Hardware Hacking and Reverse Engineering

**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!

In our January meetup [Alexander Shabalin](https://github.com/projedi) will talk about the LLVM-based backend in Kotlin and its tracing garbage collector. Alexander is a software engineer at JetBrains who works on Kotlin/Native. Kotlin/Native is one of the backends of the Kotlin compiler. It uses LLVM for code generation and it features a tracing garbage collector. The GC integration is custom and currently doesn't rely on LLVM GC extensions. In this talk we'll take a look at some Kotlin code, the LLVM code generated for it and the reasons behind it. Small snacks and drinks will be available. There is always space for outside topics and discussions. If you have specific questions, please bring them. Looking forward to meeting everyone again!

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

**The Vibe:** Agentic AI is moving too fast for „best practices.“ We are here to experiment, debug, and learn from each other. **The Plan:** I’m hosting a micro-meetup for software engineers who are actively exploring autonomous AI agents. Whether you are building with CrewAI, LangGraph, AutoGen, or experimenting with local LLMs – let’s compare notes. This is a „Lab“ session. We will: \* **Show & Tell:** Share what you are working on (even if it’s broken). \* **Dissect Approaches:** Discuss how to handle context, loops, and hallucinations in production. \* **Hands-on:** Bring your laptop. We try different setups live. The Logistics: 📍 Location: My Office in Grunewald area – Boardroom. 🎟 Capacity: Strictly limited to 6 seats. 🍕 Food/Drinks: Snacks and drinks provided. Who is this for? **Professionals eager to actively shape the future and elevate software engineering through Agentic AI.** We are looking for people ready to co-create the next generation of workflows, not just watch from the sidelines. Since we are a very small group, please only register if you are willing to actively participate in the discussion and hands-on lab work.

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right

Join this **Interview Simulation** session — to sharpen the skills for both interviews **and** architectural pitches. 💡 How it works The event is split into three parts: 1. **Most common behavioral & HR questions** \- you will receive a printed list of behavioral/HR questions and we brainstorm tips on how to prepare for them 2. **Interview Simulation (10 minute rounds)** – One participant acts as the interviewee and answers a round of behavioral and design-focused questions. Each other participant gets to ask him one interview question. 3. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) * **Technical questions** (based on your tech stack) * **Light design problems** (high-level reasoning, not code) No need to prepare anything in advance — just bring curiosity and an open mind. Feel free to bring your CV if you’d like feedback from others, or share a few words if you’re currently job hunting. If so, we will also brainstorm answers to more common questions that you were asked. Whether you’re preparing for an interview or simply want to grow as a software designer or architect, this session is for you.

**📅 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

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. 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 sponsored the Dianetics & Scientology Self-Improvement Center.

Do you want more motivation and confidence to build Lasting Relationships? This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? 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: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in 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 class is held at the Dianetics and Scientology Life Improvement Center.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

This is an in-person meeting. Would you like to know the Real You, not just a shadow of yourself? Does your life energy feel somehow trapped within? Does your self-confidence get easily shaken?

Perhaps you get weighed down with negative emotions you can't seem to shrug off. Or find yourself doing strange and irrational things - not really being yourself. We will cover why that is and tools that work to help you unearth your self, your self-confidence and motivation. This meeting will help you learn about how to effectively overcome: -Out-of-control unwanted emotions -Low self-esteem -Anxiety -Negativity -Stress -Irrational fears -Traumatic or painfully emotional incidents -Breakups -Betrayals -Feeling like you're not really yourself -Self-doubt...
