Extreme Programming

Register: [https://luma.com/london-mar5](https://luma.com/london-mar5) **Join our meetup for AI nerds, engineers & founders!** We share the latest insights about: *AI dev tools, Agent frameworks, RAG, vibe coding, and more!* ​​\*\*// FOR WHO\*\* ✅ Devs, Product peeps, Data lovers, ML engineers, Founders ✅ Anyone building with AI ⚠️ Some LLM knowledge required!\* Neo4j Session: **Living in an Agentic World (model) by Andreas Kollegger** What if we onboarded AI agents the same way we onboard employees? That's the key insight of "context graphs" - giving agents access to why decisions are made improves their performance. This leads to \*Agentic World Models\*: the convergence point where agent memory, knowledge graphs, and context graphs meet. Agents discover written policies and unwritten tribal knowledge, learn formal org structures and informal influence networks, and capture the \*decision traces\* that explain not just what happened, but why it was the right call. We'll cover: \- how to capture decisions traces \- how to query the context graph when making decisions \- a demo of what this looks like Together, we'll put context in context.

This month we have a visiting speaker from think-cell, Sebastian Theophil, who will talk to us about error handling in C++26 (with sprinkles of C++23). We also have space for a shorter talk, or lightning talks. If you would like to speak - even for just five minutes, please drop something into cppldn.uk/speak. **think-cell** will also be supporting the group by providing pizza and drinks - thanks **think-cell**! Thanks, also, to **Maven Securities** for hosting us again, this month. **As usual we'll need your full name for the door list, so we'll be asking for this on registration** (as this may be different to your username). This data will only be used for the door list/ registration and not published anywhere or used for other purposes. If you'd like to speak at a future event please get in touch at [cppldn.uk/speak](http://cppldn.uk/speak). **Here's the approximate schedule:** **18:30** *Doors open* **19:00** "Intro and news" - *Phil Nash* **19:10** *"compile_assert - Compile time C++ assertions" - Jonathan Grant* I present compile_assert(expression, message), a new C++ keyword proposal for enforcing assertions at compile time within ordinary (non-constexpr) functions. compile_assert provides advanced asserts at compile time, not runtime. Used for bounds checking, parameter validation and data validation at compile time. All three major compilers (GCC, Clang, MSVC) are supported with a sample implementation. The example implementation does this by using GCC’s attribute error which works with Clang. **19:25** "Compile-Time Data Layout Transformation with C++26 Reflection" - *Arturs Kalnins* We’ll use C++26 static reflection and injection to convert an AoS into a SoA at compile time, live on the latest GCC, with zero macros and zero boilerplate. **19:40** *break* **20:00** "To Err is Human: Robust Error Handling in C++26" - *Sebastian Theophil* A walk through the new error handling features in C++26 — including \`std::expected\`, \`std::stacktrace\`, contracts, and more — and how they can help us write more robust, maintainable code. **21:00** *Conclusion, and moving on somewhere else* \-\-\- **About the speakers** *Sebastian* has been working at think-cell since it was founded in 2002. In the last few years, among many other things, he has ported think-cell to run on macOS. He also maintains the typescripten project, which lets programmers call JavaScript libraries from C++ code compiled to WebAssembly in a convenient and type-safe way. He enjoys leaving his desk from time to time to talk at international C++ conferences. *Jonathan* has been a Software Engineer since 2003, worked in the video games industry and also embedded space for a long time at Renesas in safety critical systems for the automotive sector in C and C++. He also develops bespoke machine learning software in C++. He has a BSc Computer Science and an MSc Software Engineering. *Arturs* is a C++ software engineer with a background in aerospace engineering, where he developed a strong foundation in mathematics and systems thinking. He builds reliable, high-performance systems across embedded software, networking, and distributed platforms, with a particular focus on modern C++ (23/26), Rust, and performance-critical design. He enjoys tackling complex engineering challenges, designing clean abstractions, and contributing to the standards and practices that help teams deliver robust systems effectively.

*📌Abstract* Vibe coding captures something real: momentum. The ability to move from an idea to a working prototype at surprising speed, guided by intent, context, and AI assistance. But in an enterprise environment, speed alone isn’t enough — software must also be secure, compliant, observable, and built to last. We'll see how teams can build applications in a single, end-to-end development flow — from business requirements and early prototypes to engineering, testing, delivery, and production — without breaking context or introducing late-stage rework. At the center of this flow is the software catalog: a living system of record that connects services, APIs, data, ownership, dependencies, and standards. More than documentation, the catalog becomes the shared interface for developers, platform teams, and AI agents to understand the system and act consistently, within enterprise rules and guardrails. The goal isn’t to limit creativity, but to make flow sustainable — turning AI-driven momentum into software that’s ready for production. 🔍 *Key topics* • From vibe-coding to ai-assisted delivery in production • Software catalog as the system of record for enterprise context • AI agents operating in context continuity within guardrails ⏲️ *Agenda* 18.30\* Welcoming 18.45 Talk 19:30 Q&A 19:45 Closing remarks & Networking and Pizzas! 🍕 See you at the next Meetup! \*To access the venue, a staff member will be at the building's front entrance. The venue is on the first floor. 🎙️*Speaker* Giulio Roggero CTO @ Mia-Platform 25 years of experience in software engineering, serial entrepreneur with more than 10 business initiatives launched, today is co-founder and CTO at Mia-Platform, the Internal Developer Platform named by Gartner Cool Vendor for Software Engineering Technologies and in the Cloud Application Platforms Magic Quadrant.

**Whose knowledge is centred in design? Whose voices are heard, and whose are overlooked?** Join us for an interactive workshop that goes beyond surface-level inclusion to critically explore power, culture, and equity in design practice. **What’s the event about?** We want to create a space where we can talk honestly and practically about what it means to go beyond inclusive design — to question who design is for, how it’s done, and how we might do it differently. It’s not a lecture, nor is it about having the “right” answers. It’s about exploring the topic together in a way that’s open, hands-on… and a bit of fun too. This event will include an interactive activity designed to provoke thought and discussion about what it means to design beyond inclusivity, creating space for deeper shared reflection. **Who’s it for?** This is for anyone working in or around design — whether you’re in services, research, strategy, policy, or community roles. You might: •⁠ ⁠Be curious about the term “decolonising” but not sure where to start •⁠ ⁠Feel a bit disconnected from this kind of conversation •⁠ ⁠Be looking for a more grounded, less academic way in •⁠ ⁠Just want to meet others thinking about design and equity in new ways **What can you expect?** •⁠ ⁠A hands-on group activity inviting you to explore an unfamiliar world, challenge assumptions, and think differently about power, culture, and design •⁠ ⁠Facilitated group reflection and conversation on how we talk about — and act on — the idea of decolonising design in our work •⁠ ⁠Informal conversations and networking at the pub to follow What you’ll take away •⁠ ⁠A practical framework you can adapt or reuse in your own work •⁠ ⁠A more grounded sense of what “decolonising design” can mean in everyday practice •⁠ ⁠A chance to connect with others exploring similar questions Whether you're completely new to decolonising design or already working with these frameworks, you'll find space to reflect, learn, and connect with others navigating similar questions. **About the Ticket** The ticket cost is to hold your place and ensure commitment from attendees. **All participants who attend the event will be offered the option to request a full refund of their ticket price.** This approach helps us plan effectively while remaining accessible to those with financial constraints. Come ready to participate, question, and imagine design differently.

The Barbican Centre is a symbol of brutalist architecture. Sharp edges, concrete, light and shadow, columns and blocky shapes: it’s a place rife with opportunities for our keen eyes and blazing cameras! This maze of shapes and lines is where we will be continuing our journey towards street photography excellence. It isn't the place for complex, layered crowds. Instead, we will focus on a slower, more intentional pace—seeking out the shapes, lines, and patterns where we can purposefully place a human element to create a striking image. Open to all skill levels. Whether you shoot on a smartphone or a high-end camera, this workshop is about elevating your craft and learning to capture better, more intentional images. For those who have joined me before, I look forward to continuing our journey. We’ll be building directly on the skills you’ve already practiced, adding this new 'intentional' element to your toolkit to create even more compelling street scenes. I will be there helping you along to develop the frame and to understand how to build the image from the ground up. Join us for a great afternoon, sharing your passion with fellow photographers and taking an important step in your journey to mastering the streets with your camera! What will you need? A camera or a smartphone, of course, and a pair of comfortable shoes. And a determination to have a good time, because you certainly will! After the workshop you will be invited to join the Tap on the Shoulder WhatsApp group, where you will be able to share your best efforts from the workshop and receive feedback from me and your peers. At the end of the workshop we will be heading for the nearest pub for a refreshment and some banter, enjoying each other’s company and planning our future street photography mischief! What are you waiting for? Book your place now and take your next step in improving your street photography skills! Bring your children, they can participate as well! Attendance is free for children under 15 years of age: please use the discount code UNDER15. Please come 5-10 minutes early. I will wait for 5 minutes for late arrivals then start the workshop out of respect for the people that arrived on time!

Join this fun challenge to shoot in the style of famous photographers such as Moriyama, Cartier Bresson, Erwitt and others. This challenge is designed to stretch and encourage you to shoot a new and different type of photography. We'll start with a brief and set you into teams, look at your first challenge, then we'll go out shooting until we've worked through all the challenges. We will set the teams once everyone arrives and that way you'll have the courage (if you need it!) shooting street photography. We will stop for a coffee and review some of the images of the day. WHAT YOU WILL LEARN: * The work of famous street photographers * Composition - layering / rules / what to look for * Candid or posed and how to approach people **PAYMENT OPTIONS** * **PayPal via RSVP** * The Meetup transaction fee will be added. and you'll automatically be added to attend * **Send £25 via PayPal** to \*\*[creativebeansproductions@gmail.com**](http://creativebeansproductions@gmail.com%2A%2A/) with no extra fee. * Send us a text or comment below and we will add you to the event attendee list.

We playtest all sorts of games - strategic, silly, creative, or whatever. Some games are almost done. Some are very early ideas. We test anything that will fit into 90 minutes. You don't need to bring a game - we always love to have new playtesters! Please let us know in the comments when you plan to arrive/leave and whether you are bringing a game or not. This helps us to plan the day better. The schedule is: 10am onwards - gathering, chatting 11am sharp - playing for 90 min ('slot 1') 12:30ish - break for food/chat 1pm sharp - playing for 90 min ('slot 2') 2:30ish - break for food/chat 3pm sharp - playing for 90 min ('slot 3') 4:30ish - finish up Often, we might hang around afterwards, to play some already-published games. We are strict on timings, so please try to arrive a few minutes before the session to limit disruption. You can just come for part of the day if you wish. The reason we have fixed timings for the 3 'slots' is to make it easier for folk to do so. Designers of all levels of experience are welcome! But if it's your first time, we ask that you don't bring a game and just spend some time learning how the group works. The group works based on reciprocation. If you expect to test your own game, make sure stay for long enough to play other games. As a general rule of thumb, you can expect to play one of your own games every third 90-minute session. So if you stay a whole day (3 sessions), you can expect to have one session to play your game(s). A good rule of thumb is that if you come all day, you will have one 90 minute session with two other playtesters in which to test your own games. It is sometimes possible to test games with more players. If your game requires 4 or more, please note that as standard you will be allocated half of a session (45 minutes). Pre-covid, we were getting unmanageable. As a result, we may have to limit attendees. This is a free-to-use venue, and we have to be mindful that other folk want to use the same space. Please note: This is an adults only event. We look forward to seeing you!

## \*Please note - to be admitted to this event you must register for approval here: [https://luma.com/lcsqwmf3](https://luma.com/lcsqwmf3) This weekend hackathon brings together LangChain and SurrealDB to explore how agents can move beyond demos by grounding themselves in structured, persistent context. As agentic systems become more autonomous, their biggest failure mode isn’t model capability - it’s context. Agents struggle with accuracy, consistency, and reasoning when memory is shallow or unstructured. Knowledge graphs provide a powerful way to represent relationships, state, and history, enabling agents to reason over how things connect, not just what text is retrieved. Over the weekend, you’ll build practical agent projects using the LangChain ecosystem, with a strong emphasis on knowledge graphs and real-world retrieval workflows, using SurrealDB as a unified data layer for graph, document, vector, and temporal data. You’ll also have plenty of time to connect with both the LangChain and SurrealDB communities in London, collaborate with other builders, and get hands-on support from mentors. *** ## Schedule **Friday** * 18:00 - Doors open, check-in, pizza & drinks * Hackathon kickoff, team formation & briefing (time TBC) **Saturday** * All day - Build, iterate, mentor support (details TBC) **Sunday** * Final build, demos & judging (details TBC) * 15:30 - Closing, winners & wrap-up Full challenge details and rules will be shared ahead of the event. *** ## What you’ll work on * Agent workflows built with LangChain * Knowledge graph–driven context and memory * Hybrid retrieval patterns (vector + graph) * Persistent agent state and evolving context * Practical, production-oriented agent use cases *** ## Prizes * Swag and LangSmith credits from LangChain * Swag from SurrealDB *** ## Why attend? This is a hands-on opportunity to build credible agent projects in a single weekend, learn production-oriented patterns, and explore how structured context improves agent accuracy and reliability. You’ll collaborate with experienced builders, get direct support from the LangChain and SurrealDB teams, and connect with the wider London agent and AI engineering community. **FAQs** **Is the venue accessible?** Absolutely! There is a lift that takes you up to Level 4 where the event is held. **Is this event for me?** SurrealDB events are for software engineers, developers, architects, data scientists, data engineers, or any tech professionals keen to discover more about SurrealDB: a scalable multi-model database that allows users and developers to focus on building their applications with ease and speed. **Am I guaranteed a ticket at this event?** Our events are tech-focused and in the interest of keeping our events relevant and meaningful for those attending, tickets are issued at our discretion. We therefore reserve the right to refund ticket orders before the event and to request proof of identity and/or professional background upon entry. **Are there any House Rules?** At SurrealDB, we are committed to providing live and online events that are safe and enjoyable for all attending. Please review our [Code of Conduct](https://surrealdb.com/legal/code-of-conduct) and [Privacy Policy](https://surrealdb.com/legal/privacy) for more information. It is compulsory for all attendees to be registered with a first **and** last name in order to attend. Any attendees who do not adhere to these requirements will be refused a ticket.

Drake Lundstrom is presenting: Code Anywhere by Talking to your Phone Abstract: Have you heard the trend of people deploying code anywhere from checkout lines to doctors' offices? In this talk, you will learn how to talk to your phone and have an app on Azure to show your friend 5 minutes later. The basic DevOps tools you already know, plus a little bit of AI magic, are all you need! If you want to follow along, the demo will be in Azure with GitHub Actions and GitHub Copilot, and you can have it set up on your phone by the end of the session. Just come in with an Azure account and a GitHub repo. Join us for pizza, drinks, and networking @ Improving's office. Doors open at 5:45.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.

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!
