Ethical Hacking

Join us for an open and collaborative meetup dedicated to OpenClaw and Nvidia Nemoclaw — the emerging ecosystem for AI‑driven automation and intelligent agent workflows. Whether you're already working with Claw agents, experimenting with the tooling, integrating automations into real systems, or just curious about what’s possible, this meetup is the place to connect. **What this meetup is about** A relaxed, open discussion space for topics such as: * Building and orchestrating Claw agents. * Best practices for running and scaling ClawdBot Integrations, workflows, and experimental setups. * Secure agent execution and sandboxing. * Tools, extensions, and community‑built add‑ons. * Troubleshooting, insights, and real‑world use cases. * Ideas about the future direction of the OpenClaw ecosystem. This is a topic‑open session — everyone is welcome to bring questions, demos, ideas, or challenges they’re working on. No slides or formal agenda required. Bring snacks or drinks if you like — completely optional. We’re excited to meet developers, tinkerers, researchers, and enthusiasts who want to explore the next generation of agent‑based AI automation together.

Hello! I’m organising a coworking + socialising session for all of us who are working on projects (e.g. our own creations, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have time for both socialising AND working, we will be using the so-called “Pomodoro” technique: **50 mins deep work** (silent), followed by **10 mins break** to socialise. And then repeat! You are welcome to join whatever your personal background is, and whatever project you are working on. I (the host) speak English and German, so either language is fine. ——————————————————- AGENDA: * **Short Intro** Tell us who you are and share something about what you will be working on today * **Pomodoro Session** \- 3x \(3h\) Each Pomodoro session consists of 50 mins focused “deep work” (no talking, no interruptions, **phones on silent mode**) -> then 10 mins break: a chance to share your progress with others -> Repeat * **15 mins Wrap Up** Celebrate what you achieved and get to know others 😊 ———— The location is **Espresso House near Checkpoint Charlie** (they have multiple outlets - so be sure to go to the correct one!) Wifi + power plugs are available - but best to bring a fully charged laptop, just in case 🙃 You **do not** have to pay anything. But since we are using the café space, it is common courtesy to buy at least one drink (coffee costs roughly **4 Euros**).

We are starting a series of track sessions with Ruth and Victoria as a part of training for the upcoming Oberelbe race in Dresden. Starting from March, 4, we’ll gather at the Track of Volkspark Rehberge at 18:30 for a group training. Meeting point - the Track of Volkspark Rehberge https://maps.app.goo.gl/ryhaXFxb3v9JJzyr8?g_st=ic The last track session will take place on April, 22. Afterwards we‘ll have drinks or dinner if we feel like it. Don’t worry if you are new! Joining track sessions is a great chance to start 😉 Take care and see you soon ❤️ P.S. ‼️️ Please cancel your participation if you can’t show up, even if it’s at short notice so that we don’t wait for you. Thanks! ‼️

Join our Backgammon Meetup to play, socialize, and enjoy this classic game! Everyone’s welcome! Whether you’re a beginner or an experienced player. Expect fun, friendly games, laughter, and new friends. 👉 Please RSVP only if you plan to attend. 👉 Bring your own set if you have one. *** **How to Play (Quick Guide):** * Each player has 15 checkers and moves them toward their home board. * Dice rolls decide how many spaces you can move. * Land on an opponent’s single checker to send it to the bar. * Once all your checkers are home, start bearing off (removing them). * First to remove all checkers wins! *** **Fun Fact:** The Origin of Backgammon: Backgammon is one of the oldest known board games, with roots deeply embedded in the ancient civilisations of Mesopotamia. But it is in Persia, where the game truly flourished and evolved into what we now know as 'Takhte Nard'. Archaeological findings suggest that early forms of backgammon were played in Iran over 5,000 years ago. Artifacts such as game boards and dice have been discovered in sites like 'Shahr-e Sukhteh' (The Burnt City), indicating the game’s ancient origins.

​Collaborative improv & storytelling for social media. This event is a collaboration between [Social Rising](https://luma.com/socialrising) & [Social Adventures](https://luma.com/socialadventures) and will be announced on both channels. ​Grab your camera, microphone(s), and other equipment you already have, (re-)start your CapCut subscription, and let's meet to create content. We'll meet outside in a park, which should allow us to both have enough space to create content with each other but also find other people to interact with (don't record without approval!). ​Important: If you don't want to be in front of the camera, then don't join. You don't have to have social media, though. ​After we meet, we first get to know each other and then create stories, improve them, record them for social media, edit them right there, and post them. ​What do you need? * ​Motivation, and ideas for stories for social media * ​A mobile phone or camera * ​All equipment you have at home for filming: External/bluetooth microphones, prop, ... * ​Editing software like CapCut or Filmora directly on your phone. ​​The event starts at 14:00 and lasts up to 2 hours. ​We'll meet at Tiergarten at the following spot: [https://maps.app.goo.gl/dzXw9NXMLAjBqBUE9](https://maps.app.goo.gl/dzXw9NXMLAjBqBUE9) ​The communication before, during and after the event happens in our Telegram group: [https://t.me/czc_berlin](https://t.me/czc_berlin?utm_source=luma).

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

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.
