Vibe Coding Collective is teaming up with **ElevenLabs** to push the boundaries of sound-first vibe coded apps. For one night, we’re getting full access to their tech to explore what’s possible when vibe coding meets voice and music generation. Whether you want to build a voice-controlled game, an AI storyteller, or a children’s app, this is your playground. Use any tools you like (Lovable, Google AI Studio, v0, Cursor, Replit…) and plug in ElevenLabs' power. 🍻 **Format 🛠️** We’ll be teaming up in small groups (2–3 people). We'll provide a specific "Voice & Vibe" challenge, then it’s heads-down building. The goal is to **vibe, experiment with sound, and see how voice and music changes the way we interact with vibe coding**. ## New to vibe coding or voice tech? ✨ No worries! We’ll provide a special **ElevenLabs Starter Kit** with API recipes and prompt examples so even total beginners can get an AI talking in minutes. ## Schedule 🕒 *(Aim to arrive by 6:50 PM so we can get your API access sorted!)* * 7:00 – ElevenLabs Presentation & Tech Demo * 7:20 – The Challenge + Team Formation 🤝 * 7:30 – Round 1: Build & Hear 💻 * 8:15 – Break (Grab a drink, hear what others are cooking) 🍺 * 8:30 – Round 2: Polish & Play 🏗️ * 9:00 – The "Vibe Check" Demos 📺 (Show/Hear what you built!) * 9:20 – Hang out, network, make friends ✌️ ## Who is it for?

**A software engineers guide to LLMs** In this talk Richard Conway will break down what LLMs are layer by layer, how they work, how they use software principles to work and how to use them in software. This will be a fluid talk with a lot of philosophy, maths from school and how to build your software understanding things like hallucinations and new techniques that can make your management of LLMs more deterministic. We'll consider a lot of things here including the new code generation tools which have developers quivering in their boots, what they mean for our industry and how to use them for effect. Lots of mini-demos and great discussions, good people, beer and pizza! **About the speaker** Richard Conway co-founded the user group, along with Andy Cross, Joe Hancock and Chris Parsons. He is a Microsoft AI MVP and a Microsoft Regional Director and has been writing software in one form or another since his fingers were large enough to hit a ZX81 keyboard.

This talk introduces the core principles of federation and why it matters for modern OLAP workloads. Using StarRocks as a model system, we highlight its vectorised execution engine, native connectors, and deep Apache Iceberg integration that together deliver high-performance lakehouse querying. 2. [Ben Guerin](https://www.linkedin.com/in/bjhguerin/) **How I Learned to Stop Worrying and Let Claude Code Write the Python [the story of [ismypubfucked.com](http://ismypubfucked.com/ "http://ismypubfucked.com")]** 43,000 pubs. Official VOA data. One question. [ismypubfucked.com](http://ismypubfucked.com/ "http://ismypubfucked.com") got 400k visits in two weeks and wall-to-wall media coverage: from the Mirror to the Telegraph to City AM. I'm not a Python developer. I used Claude Code to wrangle government spreadsheets, match them to OpenStreetMap, and ship a working site. All in less than 6 hours from initial idea to a live website. The AI wrote the Python, I just knew what story the data could tell. This talk covers what happens when tools like Claude Code unlock Python for people who think in narratives rather than syntax, and what a decade of building viral campaigns has taught me about making people actually give a shit about spreadsheets. **Lightning Talks** 1. **TBC** 2. **TBC** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Logistics** Doors open at **6.30 pm** (get there early as you'll need to sign in with building security).

### 📅 EVENT DETAILS 📍 **Where:** Aldgate Tower (just outside Aldgate East Station, Exit 1) 🙋 **Who:** Players who already know how to play with scores (not suitable for beginners) ☕ **Included:** Instructor help, free tea, coffee, and unbeatable vibes ## 🀄 WANT TO PLAY MAHJONG REGULARLY? Mahjong is still a niche board game in London — and since it needs **4 players**, it can be hard to organise regular games with just your own friends or family. In many parts of Asia, **Mahjong parlours** bring people together to play. While we’re **not** running a commercial Mahjong club, we *are* here to build a **community**. Many of our players started as complete beginners in our workshops — and now they’re **hooked**! That’s why we created our **🎟️ Just Play tickets**. ### 🌏 DIFFERENT MAHJONG STYLES WELCOME ### 🇭🇰 Hong Kong Style (Main Style) Our main style is **Hong Kong Mahjong**, with a **3 fan minimum to win**.If you know how to play other Chinese styles like **Taiwanese**, **Sichuan**, or **British Mahjong**, you’re still welcome! We’ll provide **scoring cards** to help you adapt. ⚠️ However, these tables are **not suitable for beginners**. If you haven’t yet graduated from Level 1 or Level 2 of our workshops, or if you don’t know how to score, please join our learner workshops first to build confidence. ### 🇯🇵 Japanese Riichi (Growing Community) Riichi Mahjong is **new to our community**, but we love its fast pace and strategic complexity!If you already know how to play Riichi — \*\*amazing! Please join us.\*\*If you play Chinese Mahjong and want to try Riichi, one of our instructors or friendly regulars might help, but we **can’t guarantee full teaching support yet**. You're welcome to learn by playing alongside others. ### 🇺🇸 American Mahjong (New Community in 2026) We’re excited to add **American Mahjong** to our offerings. It’s quite different from Chinese Mahjong, so we’ll run newbie workshops and regular Just Play sessions from 2026. **Note**: Just Play bookings require solid prior knowledge of American rules. However, we encourage cross‑style learning, so if you already know one style of Mahjong, learn another with us, so you can play at any table. ## 💷 OUR BEST PRICE PROMISE We’re doing our best to keep **Just Play tickets affordable** for a 2-hour session — that’s our **best price promise**. 🙌 Unlike clubs that charge entry or venues that require a minimum spend, our ticket price covers only what’s needed: venue, staff, admin cost. And yes — with a booked ticket, **YOU ARE GUARNATEED A SEAT AT THE TABLE**, and we also provide **free tea, coffee**, and the occasional **festive treat**. ☕🍪 We're not a charity, but we are **deeply committed** to creating a welcoming Mahjong community. 💛 Your support helps us keep the tiles clicking, and we love seeing familiar faces return week after week! ## 📱 JOIN OUR MAHJONG WHATSAPP COMMUNITY Stay connected with fellow players in our friendly WhatsApp group — a space to ask questions, get updates on upcoming events, and even arrange private games outside of our Saturday sessions. It's the easiest way to stay in the loop and grow your Mahjong circle! [LINK HERE](https://chat.whatsapp.com/IQXv3nGfbeMCfvI6HsGjfZ "https://chat.whatsapp.com/IQXv3nGfbeMCfvI6HsGjfZ") **Important Notes** 1.

Join us both online and in London for a deep dive into how JVM developers can lead the next wave of innovation with agent-based systems. We’re excited to host Rod Johnson, creator of Spring, as he introduces Embabel, a new framework designed to push Java and Kotlin to the forefront of agentic AI. From building safe, testable, and enterprise-ready AI agents to rethinking how Java fits into the Gen AI ecosystem, this session will give you a front-row seat to what’s next. Whether you join us virtually or in person at Tessl HQ, expect an evening of cutting-edge ideas, practical insights, and great conversations with the Java community. Can’t make it in person?

Building predictable, safe, manageable, testable agents that integrate with existing enterprise systems is critically important to us all. ​In this session, Rod Johnson will show how JVM developers can be central to unlocking the business value of agentic AI, using the Embabel agent framework: [https://github.com/embabel/embabel-agent](https://github.com/embabel/embabel-agent) Embabel is an innovative framework for Java and Kotlin developers, seamlessly integrated with Spring. Built in Kotlin, it aims not to play catchup with Python frameworks like Crew AI, but to leapfrog them to be the best agent framework, period. ​Embabel innovates in several ways. It introduces a planning step that maximizes autonomy while maintaining determinism and safety. It is type safe, ensuring excellent toolability and avoiding errors in prompts. It enables developers to use a rich domain model, defining not just types but behavior exposed to user code and to LLMs as tools. ​ Read more about the [vision](https://medium.com/@springrod/the-embabel-vision-967654f13793?utm_source=luma); and also the call to action for Java developers in recent Devoxx keynote: [https://www.youtube.com/watch?v=dbx1_P7W1DM](https://www.youtube.com/watch?v=dbx1_P7W1DM&utm_source=luma) **​Rod Johnson, Creator of the Spring Framework and Embabel Agent Framework** ​ Rod Johnson is a developer, author, entrepreneur and advisor.

Agents are writing code, running workflows, and building other agents. ​ The challenge isn’t basic functionality. It’s getting these systems to operate predictably in production, and integrating them into how teams build and ship software. ​This session covers both. ​ From a production lens: how to build agentic systems using spec-driven development, structured context, and evaluation loops that hold up at scale. ​From a human lens: what breaks when agents become collaborators. Ownership, coordination, and how teams actually adapt. ​Speakers: ​**Clifton Cunningham** ​**Member of Technical Staff, [guidemode.dev](https://guidemode.dev/?utm_source=luma) \| Former CTO at DailyMail\, Infinitas Learning\, TES Global** ​Clifton will explore what happens when AI agents become part of your team. Drawing on experience leading large-scale engineering organisations, he’ll unpack the human, cultural, and operational challenges of working alongside AI colleagues. ​**Alfonso Graziano** ​**AI Tech Lead\, Nearform \| Author of *AI-Native Software Engineering*** ​Alfonso will walk through how to build agents that build and maintain other agents. A practical, production-focused session covering spec-driven development, context engineering, evaluation loops, and how to make agentic systems reliable at scale. ​ Join us for pizza, drinks, and practical AI insights.

**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** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

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.
