Mobile Game Development

What if your AI agent could talk to other agents… without you in the middle? 👀 Welcome to **Sprint #2 of the Agentic AI Engineering Lab** — a hands-on playground for developers, tinkerers, and curious minds. This time, we’re diving into the **[A2A (Agent-to-Agent) Protocol](https://a2a-protocol.org/)**, an emerging open standard designed to enable seamless communication and collaboration between autonomous AI agents. We won’t just talk about it....We’ll build, experiment and break it. Join us to see what happens. *** ### 🧪 What We’ll Do **10:00** — Quick round of introductions **10:10** — Intro session: Understanding the A2A Protocol **10:30** — Build time (hands-on experimentation) **12:00** — Live demos + technical teardown **12:45** — Wrap-up + takeaways *** ### 🚀 What to Expect * Hands-on building, not passive listening * Real agent-to-agent experiments * Collaboration with fellow builders * Fast ideas, quick tests, lots of learning *** ### 🚫 What Not to Expect * Long lectures * Step-by-step tutorials * Sales pitches * Perfect code This is a **lab** — we learn by building, breaking, and iterating. *** ### 👩‍💻 Who Should Join Curious developers, tinkerers, and engineers, with basic knowledge of AI Agents. Bring: * Laptop with dev setup * Access to an LLM (Claude / OpenAI / Ollama) * Comfort building small things in any language *** ### 📍 Location We first assemble at **Steinecke** (opposite **Martin-Luther Hospital**) before heading to the private boardroom. So, please **arrive before 10:00 AM CET.** Spots are limited to keep it interactive.

You are invited to a Cookies&Boardgames evening in Charlottenburg. There is enough space for 3 board game tables and about 15 people. In addition to this meetup participants, other people from my board game group will join. My games collection includes party games like Code Names, Saboteur, Camel Cup, euro games like Wingspan, Ecos, Photosynthesis, dexterity games like Menara and Junk Art, and some heavy weights like Tapestry and Civilization. Feel free to bring your own board games too :) My apartment is in short walking distance from Messe Nord subway station. You will get the full address to my apartment via meetup app message. Kind regards, Sebastian

Saturday afternoon is perfect to play some lazy liar games, if you have nothing better to do. We are a group of friendly people who will teach you how to play these easy social deduction games . Amazing way to meet new people and have some good company during weekend. **IMPORTANT** It's relaxed playing, nothing for ambitious gamers or people who take it too serious. Waiting list policy: When spots open up, we try to bring in a good mix — some regulars we can count on and some new faces to keep things fresh. That means not everyone will get picked every time, but don’t take it the wrong way — it’s just about balance. There’ll always be more chances to join!

Hi Footballers, We play in the format 8v8 for a full hour. The pitch is a modern artificial turf (outdoor) in Safe-Hub Berlin. The fee to participate is 7.49€. In order to sign up for the game, you would need to download the mobile app "CeleBreak", where you can sign up for the game and pay the participating fee. You can download the app for free from the AppStore and Google Play App Store. Download the **CeleBreak App** here: [https://onelink.to/celebreak](http://onelink.to/celebreak) Visit our **Website**: [https://app.celebreak.com/](https://app.celebreak.com/) An organizer will welcome you at the pitch and provides bibs and balls for the game. **Female and male players of all skill levels are welcome!** :-) Hope to see you soon on the pitch Marius PS: No worries about the event attendees number on Meet Up - the real sign up number of players for a game you will see in the app!

*Trialing a new location now that Brewdog has closed, please bear with us while we get back on our feet :)* Hi folks, this is the special meetup group for the weekly Sunday Blood on the Clocktower games in Berlin, currently at BRLO Brwhaus near Potsdamer Platz. We run beginner-friendly and intermediate-level games throughout the afternoon and evening. **Friendly newcomers of all skill levels are welcome, no experience required!** Our group aims to provide a fun and welcoming space to experience this thrilling game of social deception. **We focus on promoting a positive and fun group atmosphere, where players don’t take themselves or the game too seriously, whether they’re heroically winning or spectacularly losing.** Our players follow the code of conduct for the Berlin Board Gamers group and are expected to treat each other with respect and consideration – “killing with grace, and dying with dignity”. We are usually able to offer two simultaneous games on Sundays. If you are marked as "attending" in Meetup and are in your seat at 15:00, your place is guaranteed for as long as you want to stay. All other seats are first come, first served. We always run at least one beginner-friendly game of the basic version of Clocktower ("Trouble Brewing") throughout the afternoon and evening. We also usually have enough players for a second intermediate-level game. If you are already very familiar with Clocktower, consider also joining our Tuesday meetup for advanced players, when we play with complex custom scripts and characters. Blood on the Clocktower is a deep, mechanical game of murder and mystery, lies and logic, deduction and deception… think Werewolf on steroids. Each player receives a unique secret role and plays either for the good team – the uninformed majority, gathering info and working with others to solve the puzzle – or the evil team, the informed minority, scheming to eliminate good players and protect their demon from execution. In our beginner games no prior experience is expected and we will gladly explain the game rules to any newcomers. We play in English so players should be able to understand and express themselves in English: an exception is possible for one pair of players willing to play together (as a “Revolutionary” pair) where one player can interpret into and out of English. Please let us know in advance if this is the case.

Your child will sketch their character to ground their imagination in reality\. **3\. The Magic of AI** \- We introduce the kids to "The Helpful Robot" \- a friendly AI that takes their verbal descriptions and sketches and helps turn them into stunning\, book\-quality illustrations\. The future of creativity\! **4\. The Grand Pitch** \- Every child gets their "Author Moment\." They will present their character and story to the group\, building vital communication skills and pride in their work\. ### **📚 The "Little Storysmiths" Keepsake** The workshop doesn’t end when you leave the room. * The Digital Preview: You will receive a PDF version of your child’s story shortly after the workshop. * The Physical Book: About a week later, you will receive a high-quality, printed storybook authored and directed by your child. It is a one-of-a-kind treasure for your bookshelf. ### **📚 Story reading party!** Join us in the story reading party where kids bring their physical, printed books and proudly read their stories to friends and family! Your friends are invited! ### **Workshop Details at a Glance** * Ages: 5 - 7 years old. * Tools Provided: All drawing materials, prompts, and AI software. * Takeaway: 1 x Digital Storybook, 1 x Physical Printed Book (printed later) * Story reading party: follow-up event where kids can read from their physical books to friends and family **\#\#\# Form to register \-** [https://berlinbusinessinstitute.com/little-storysmiths/](https://berlinbusinessinstitute.com/little-storysmiths/)

Join us for a night of board gaming with FANG (Fem All Night Gaming). **We are an all fem board game group** in Columbus, Ohio. No cis-men, please! We play modern hobby board games! If you're unsure what that is, we can teach you! We'll be meeting on the second floor of Giant Eagle in their cafe area. Giant Eagle has a lot of food and beverage options including their hot foods bars. You are also welcome to bring in any outside food.

**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
