Coders

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++.

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.

You can expect a friendly introduction to the sport, but in all honesty you will dive in at the deep end to learn UWR. Please bring swimwear and an open mind and expectation to have fun. We can lend an UWR hat, snorkle, mask and fins. Although if you have them already it is better to bring your own. Expect to swim, dive to 4m depth, hold your breath longer than you thought you could, be involved in drills and games. It is full contact and you will be wrestling other players to take the ball and pass to your team or score a goal. Please get on touch with questions or intent to attend prior to session so that we can support with kit etc.

*📌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.

**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.

## \*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!

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!

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

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
