Welcome to our cosy Godot Engine Community Meetup! This is not a structured meeting, but rather a friendly get-together. We will hang out, chat and maybe show some of our current projects! 🦜 Regardless if you are an artist, designer, programmer, beginner, hobbyist, professional or anything in between: join us for sharing knowledge, creating art together, coding together, joining game jams together and having fun! 🌼 This meetup will happen at [Saftladen Game Collective](https://saftladen.berlin), Normannenstraße 1-2, 10367 Berlin-Lichtenberg. 🌳 You can also join us on [our Discord Server](https://discord.gg/Sm3CgrqqQa). ☎️ Follow us on [Mastodon](https://mastodon.gamedev.place/@GodotUserGroupBerlin) for updates. 📢 Also check out [our website](https://godot.berlin). 🌐 Please be [excellent to each other](https://godotengine.org/code-of-conduct/)! 🕊️

Register: [https://globalai.community/chapters/berlin/events/ai-memory-and-founders-night/](https://globalai.community/chapters/berlin/events/ai-memory-and-founders-night/) This edition of the **Global AI Berlin** meetup focuses on one of the most critical topics for modern AI systems: **AI Memory** and its role in shaping the next generation of intelligent applications. The event brings together founders, product leaders, and engineers to explore how memory is designed, structured, and operationalized in real-world AI systems. With contributions from teams at **Neo4j, Cognee, MemVerge, Riverty and more**, and the broader Berlin AI community, the discussions will cover practical approaches to building memory-enabled applications at production scale.

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 turned the entire learning experience into ***Comprehensible Input* through both simplified and traditional manga** with support for **Zhuyin**, **Pinyin**, **flashcards**, **audio**, **direct translation**, an integrated dictionary. We also specifically design region-specific language to reflect real-life usage in both **mainland Chinese Mandarin** and **Taiwanese Mandarin**, allowing you to naturally compare and explore the differences between the two, so you don’t end up saying something that makes perfect sense in Beijing, but gets you funny looks in Taipei 😏.

A space for working on projects & learning new stuff together. 💻☕️ Please RSVP if you intend to join, as we have limited space. 😊

RSVP on Luma: https://luma.com/zx2l0ais?utm_source=meetup Silent Reading / Creating Club is a gathering for people who enjoy focusing together in public. Bring a book, a notebook, a sketchpad, knitting needles — whatever you’d like to spend a quiet hour with. All projects and all participants are welcome. ​This year is about creating more — quietly, consistently, imperfectly — and shaping environments that support that. If you’re building something of your own, you’re especially welcome here. ​We’re building a community of readers and creators who value depth, presence, and shared silence. The magic isn’t just in the quiet hour — it’s in the people who return and make it feel like a familiar room. ​(Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist.) ​This quiet ritual unfolds at **W66 Café**. ​There’s no entrance fee, but please order at least one item from the café and don’t bring outside drinks 🙂 ​No assignments. No pressure. No productivity race. Just a shared hour of intentional silence, followed by relaxed conversation. 🕰 Our Agenda ​**10:30 – 11:00** Arrivals, ordering drinks/food, light social time ​**11:00 – 12:00** The Great Quiet Hour (Read. Write. Sketch. Code. Think. Sit.) ​**12:00 – 12:30** Optional socializing — share what you were reading or creating, or simply continue in quiet focus. ## **​🏡 House Guidelines** ​To keep this space calm and welcoming for everyone: ​• Silence during the focus hour (no calls or conversations) • Phones on silent mode • If using a laptop, please avoid meetings or audio — headphones welcome • Arrive before 11:00 if possible to minimize disruptions

**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** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

On Thursday, March 12, 2026, we will meet at the TEKSystems offices at 700 N Hurstbourne Pkwy.

Afterward, we will go to Brick House Tavern for drinks and food to continue the conversation. The session will also be broadcast at https://twitch.tv/TaleLearnCode. ### Much Ado About Nullable - C# Nullable Reference Types Explained In 2019 (C# 8.0) Microsoft introduced a feature that has generated a lot of confusion, debate and outright dissent. I'm talking about Nullable Reference Types. In this presentation, I we dig into this feature, explore why it exists, what problem it tries to solve, how it works, and how people have critiqued it, so that you as a programmer can decide if and how you want to use it.

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

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!
