This is a space for open discussions, knowledge sharing, and networking among professionals working on decentralized technologies. Each month, we come together to share projects, discuss challenges, and exchange ideas on navigating the LFDT ecosystem. Whether you're looking for insights, solutions, or just good company, you'll find a supportive community eager to collaborate and help. There’s no formal agenda—just organic discussions on the latest developments, real-world applications, and ways to make decentralized trust more impactful. Whether you’re an industry expert or just starting out, you’re welcome to join us, contribute, or just listen in. Come grab a drink, meet like-minded people, and let’s build the future of decentralized trust together!

Or are you already familiar with all the essentials and lacking the motivation to master the rest? Or perhaps you're already pretty fluent in Rust but never got a chance to code for constrained environments while were always curious about that? If you answered "yes" to any of these questions, you're in luck! In this talk, I'll introduce a new project, that makes Rust programming a lot of fun, especially if you're fascinated by pixel art and/or retrogaming. * **Reimagining the terminal with Rust** The terminal has evolved far beyond plain text interfaces. In this talk, we'll explore how Rust is pushing the boundaries of what's possible in terminal applications. * Open mic / lightning talks * Networking **Speakers** 1.

Two talks. One evening. Plenty of ideas to take home. We’re ready to kick things off for another Berlin Meetup, and are happy to present the speakers of the evening: **[Jens Wriske](https://www.linkedin.com/in/jens-wriske-8b538a397/):** ***"Designing APIs on top of Data Platforms using Databricks"*** Modern data platforms increasingly follow a lakehouse architecture, where data remains owned and governed by domain teams rather than application developers. This session explores how APIs can be designed on top of Azure Databricks to provide access to heterogeneous data sources without duplicating or owning the underlying storage layer. **[Tanuj Jain](https://www.linkedin.com/in/tanuj-jain-10/): *"The Story Behind the Story: "Building a Contextual News Chatbot."*** Most news readers lack the background to fully engage with the stories they encounter. This talk walks through the development of a chatbot embedded in a news article page for a German news publisher, designed to give readers on-demand context about what they're reading. We share the key technical and product decisions made along the way, and what we learned about building an AI feature that sits at the intersection of editorial and user experience. ✧ ✧ ✧ **What to expect:** * Two expert talks and Q&A * Networking opportunities in our great Creator Space * Some snacks & drinks to fuel your thoughts : ) ✧ ✧ ✧ **Timetable:** * 18:30 - Event admission * 18:50 - Welcome & Introduction * 19:00 - Jens Wriske: *"Designing APIs on top of Data Platforms using Databricks"* * 19:30 - 5 minutes break * 19:35 - Tanuj Jain: *"The Story Behind the Story: Building a Contextual News Chatbot"* * 20:05 - Snacks, Drinks & Networking * 21:30 - End ✧ ✧ ✧ More on the **-> [applydata data engineering meetup page](https://applydata.io/data-engineering-meetup/)**. **Our goal is to form a local data-loving community, so join us and let's talk data together!** ✧ ✧ ✧ *At the event, sound, image and video recordings are created and published for documentation purposes as well as for the presentation of the event in publicly accessible media, on websites and blogs and for presentation on social media.

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!\* \| \| \| \|

We've moved to guild.host Look for us there. https://guild.host/events/buckeye-cocoaheads-nscoders-tcbrk5

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Join us for a beautiful walk in the park this Tuesday at 7 pm! We will hike two miles through the beautiful landscaped gardens of Inniswood Metro Park. Our trail will be a combo of boardwalks, dirt trails and paved paths winding through the flowers and woods.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Join us for the best **fireworks** show in the Columbus area, [Dublin Independence Day Celebration](https://www.visitdublinohio.com/event/independence-day-celebration/203/)! **7pm**: *We'll gather at **Urban's Pint House*** to meet n greet for a bit and grab some drinks and eats. **8:30pm**: *Head over the* **Bridge to Old Dublin** and **Getaway Brewing** (*second meetup spot*). **9:30pm**: *walk across the street to secure space on the* **top level of the Library Parking Garage.** **9:50pm**: **FIREWORKS SHOW!** **AFTERPARTY**: traffic is bad for a while so either get in line to exit the parking garage OR hang out at **PINS** (or Roosevelt Room) open til late back at Bridge Park. **PARKING**: the garages all around Bridge Park are free!
