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://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, we have the following topics lined up: * Tobias has been working on a ***project wizard*** and would like to receive some feedback from the group. * Crop is going to introduce the topic of ***atomics***, then hold a discussion space for answering questions and sharing experiences. * Raf finally would like to introduce ***test-driven development*** with a small mob coding exercise. 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). 16 April 2026 is our thirteenth meeting. Our next projected meetings are going to occur on the following dates: * 14 May 2026 (tentative, public holiday) * 11 Jun 2026 * 9 Jul 2026 * 6 Aug 2026 * 3 Sep 2026 * 1 Oct 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!

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!\*\***

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. Ask the barista/bartender if you can't find us.

Do you want to start building AI agents, but never had a chance to start? Are you an experienced agent builder and you want to test your skills in a fun environment? Are you a non-technical person who wants to get a taste of building AI agents? Are you an AI agent? Then come and let’s have some fun. **Format** We will have an AI agent competition. We will build agents and let them compete in how fast they can escape from a dungeon with challenges! Never built agents before? Don't worry, we'll provide a template of an agent. Not a technical person? Don't worry, we'll provide a visual agent builder (you can build agents from your smartphone) There will be 2 leagues: * Beginners: no skills of agent building or software engineering needed - you will only need a smartphone. * Advanced: bring your laptop with your favorite agent development tools **Prerequisites**: * **a Google account** (to sign in into the competition platform) * **readiness to spend ca. 5-10 EUR on OpenRouter API credits** (unless you already have a subscription to some LLM provider allowing API usage) * **(optional) laptop with your preferred development environment for building agents** (alternatively you can use a web-based agent builder from your smartphone, but it only allows relatively simple agent configurations)

Semi in honor of March being International Women's Month Columbus libraries: [https://cml.bibliocommons.com/v2/record/S105C3454709](https://cml.bibliocommons.com/v2/record/S105C3454709) Location: SOW Plated Menu: [https://www.sowplated.com/menu-brunch/](https://www.sowplated.com/menu-brunch/) Book summary: In 2006 Julia Lerner is living in Moscow, a recent university graduate in computer science, when she's recruited by Russia's largest intelligence agency. By 2018 she's in Silicon Valley as COO of Tangerine, one of America's most famous technology companies. In between her executive management (make offers to promising startups, crush them and copy their features if they refuse); self promotion (check out her latest op-ed in the WSJ, on Work/Life Balance 2.0); and work in gender equality (transfer the most annoying females from her team), she funnels intelligence back to the motherland. But now Russia's asking for more, and Julia's getting nervous. Alice Lu is a first generation Chinese American whose parents are delighted she's working at Tangerine (such a successful company!). Too bad she's slogging away in the lower echelons, recently dumped, and now sharing her expensive two-bedroom apartment with her cousin Cheri, a perennial "founder's girlfriend". One afternoon, while performing a server check, Alice discovers some unusual activity, and now she's burdened with two powerful but distressing suspicions: Tangerine's privacy settings aren't as rigorous as the company claims they are, and the person abusing this loophole might be Julia Lerner herself. The closer Alice gets to Julia, the more Julia questions her own loyalties. Russia may have placed her in the Valley, but she's the one who built her career; isn't she entitled to protect the lifestyle she's earned?

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
