Ethical Hacking

**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!

**Please note that we invite people through different channels, so there are more attendees than you can see here :)** Is there a thought that’s been on your mind for a while — one you’d like to explore with others in a focused, open-minded, and safe setting? In our next discussion experiment, we will create a space for just that. You will have the opportunity to explain your thought and the aspect that interests you most. We will then take some time as a group to examine it in a moderated discussion. **What kind of thought can I bring?** Pretty much anything you’d like to hear other people’s perspectives on. Perhaps you have been thinking about a philosophical, societal, moral, or a personal question. A thought you find fascinating, intriguing, confusing or tricky to explain, maybe even one you usually keep to yourself for fear of being misunderstood. **What can I expect from the event?** As this is an experimental event, we’re not completely sure how it will turn out — but here’s what we will do: * Once we start, we will ask for volunteers to contribute a question * We will dedicate up to 25 minutes per person and question * You will be able to share and clarify your question before we collect thoughts on it * We’ll use an experimental facilitation technique that slows the discussion down and helps us avoid getting sidetracked or lost in terminology and definitions That way, we want to create a curious, playful container in which we can take thoughts apart and compare different takes without arguing or trying to win debates. Find out more in the FAQ below, or [send us an email](mailto:info@diskussions-experiment.de "mailto:info@diskussions-experiment.de") if you have any questions! This event is brought to you in partnership with Moe, an app that helps you find the people in your life who are seeking the same kind of connection you are – whether that’s deep conversation, creative improv, or something else entirely. Haven’t tried Moe yet? We’ll do a quick intro at the event, and then you’ll be able to use him to discover future gatherings & people that match your interests. +++++++++ **FAQ** ***Who is this event for?*** This event is for anyone who is curious and open minded. We aim to create spaces where people of all ages, identities, and backgrounds feel welcome. You don’t need to prepare anything, have strong opinions, or be extroverted to take part. ***Do I have to actively participate, or can I just listen?*** It’s perfectly fine to just listen. You can decide for yourself at any time how active you want to be and will not be asked to speak. However, there might be breakout groups, i.e. short segments in which all participants talk in groups of 2-3 people. You do not have to participate in these; you can use the time for a break instead. ***What’s the duration of the event?*** Each event lasts between 1.5 and 2 hours. Feel free to stay a bit longer to finish the snacks, chat with other participants, and deepen the conversation. ***Is the venue wheelchair accessible?*** The venue is on the ground floor and accessible with wheelchairs. However, there are unfortunately no wheelchair-accessible bathrooms! ***What is "The Discussion Experiment"*** The Discussion Experiment is an ongoing series of events through which we continuously test methods that foster more meaningful and inspiring group conversations. Among other things, we experiment with techniques that slow down discussions, improve clarity, and support participants in expressing their ideas more effectively.

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

**📅 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

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

This meetup is a relaxed kick-off for everyone who’s curious about building something together. The idea: creating a playful scavenger hunt for Berlin — step by step, as a community. Not as a fixed project yet, but as an open exploration of what could be fun, meaningful, and doable together. This first meetup is a thinking and exchange space: * What makes a great scavenger hunt? * Digital or analogue? * Small and simple, or a bit more ambitious? * How could we collaborate in a way that feels light and sustainable? You don’t need any prior experience, skills, or commitment. Just curiosity, ideas, and an interest in making things with others. This meetup is part of our **Maker Octopus** 🐙 spirit — about experimenting, co-creating, and letting ideas grow through shared action. Meet your host I’m Julia — a Berlin local who loves bringing people together. My path went from growing up in a dance school to studying philosophy to working in IT support, and somehow all of that led me here: hosting meetups and creating spaces where people can show up, relax, and connect.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

How do we recover from having had a toxic or narcissistic ex? How do we move on from the past, especially something as traumatic as a divorce or breakup? How do we avoid anxiety and depression? How do we have more self esteem? In this meeting, you will learn the mental health secrets to help you quickly get over the past and heal your mind. 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 Dianetics & Scientology life improvement center.

**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 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA
