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.

Join OutdoorLads popular weekly Thursday Bouldering evening at The Arch in Bermondsey. OutdoorLads London boulderers welcome all members of the LGBTQ+ community You'll be meeting with a supportive group of 5 to 10 plus boulderers who are always happy to introduce complete beginners or solve difficult bouldering problems with enthusiasts. We usually follow up with a pub visit. This event is for members of all levels of experience and all are welcome to come along to any of the sessions. Bouldering is a form of climbing where instead of long high routes, the 'problems', as they are referred to, tend to be shorter and focus on technique, balance, body positioning and sometimes power. Because of this different emphasis, bouldering doesn't have the hassle of climbing with ropes, harnesses and belaying, which makes the activities excellent for newcomers to the sport. If you're a seasoned climber you won't need convincing about the benefits of bouldering, but for those who've never climbed more than a staircase, the benefits are wide ranging: from the physical - improved strength, tone, balance, power and coordination; mental - problem solving, focus, concentration and body awareness; to the emotional - relaxation, a sense of achievement and a feeling that mind and body are working together perfectly ('feeling psyched'). On top of all this, bouldering tends to be a very social sport where you can hang out with mates and each have a go as you feel regardless of what level you climb at.

Ready to get outside? Our Thursday morning session in Dulwich park is back! At this moment we can meet with up to 30 people (of more than two households) to do outdoor exercise and walks. However, i like to keep our exercise groups small, so I have set the maximum participants at 12. For now this walk is for our experienced Nordic Walkers only, who already used to Nordic Walk with us regularly before Covid 19 kept us indoors, and who have their own Nordic Walking poles. As this session is outdoors, we will not ask you to wear a face mask, but we do ask you to keep 2 meters apart. Some of our walkers might be immune compromised or more at risk, so please help us keep everyone safe! Please do not come to the session and stay at home if: - you know you have been in contact - in the last 2 weeks- with someone with symptoms of possible Covid, or if you have been in contact with someone who tested positive. - you have any of the following symptoms: (new) Loss of smell/taste, Persistent cough, Fatigue, Loss of appetite, Skin rash, Hives, Fever, Severe muscle pain, Shortness of breath, Diarrhoea, Delirium, Abdominal pain, Chest pain, Hoarse voice, Eye soreness, Sore or painful throat, Nausea or vomiting, Headache, Dizziness or light headedness We meet by the cafe in the middle of the park. Session Price: £10 per session, £89 for a 10-session card or £70 unlimited sessions per month. Session cards and pay Monthly can be used in any of our outdoor walks or indoor Zoom classes sessions (except for the Parkinson's sessions). Pay What Works: The price shown above is the “true” value of the session that best reflects the work I put into preparing and leading your session. However, I understand that not everyone can afford to pay full price, and I don’t want that to stop you from joining us. In an effort to find a balance between more financial accessibility and sustainable pricing, I now offer a “Pay What Works” model. This allows for financial flexibility while still valuing and respecting the work and energy I provide in creating and delivering these classes. Then send an email to ailien@fitandhappyoutdoors.com with the heading “INVOICE please”- followed by “FAHO 1” to pay full price as quoted below, “FAHO 2”, for 20% off, or “FAHO 3” for 50% off. Pllease do tell me if you want to pay for 10 sessions, or if you’d like to pay monthly. I prefer payment by bank transfer, but if that is not possible you could pay in cash. No cheques please, the queues by the banks are just too long. We walk in all safe weather conditions – if a walk is cancelled, we will contact you to let you know. Please check for text messages or Meetup messages before leaving home!

*📌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.

## \*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.

Join OutdoorLads weekly Saturday bouldering morning event at Vauxwall West - please check our main event page on our website (link in the comments below). We welcome all members of the LGBTQ+ community, and you will be socialising with a supportive group boulderers who are always happy to introduce complete beginners to the sport or solve difficult bouldering problems together. This event is for members of all levels of experience and all are welcome to come along to any of the sessions. Bouldering is unique. There are few sports out there that offer a mental and physical challenge no matter what skill level you are at. Each route consists of several holds that the climber uses, focusing on problem-solving and technical movements to help them reach the top. No two routes are ever the same, and the colour-coded system indicates the difficulty level, so there's a climb for everyone to enjoy! If you have never tried bouldering before, please ensure that you have gone through the centre's safety and induction video beforehand (https://londonclimbingcentres.co.uk/pre-register/) as you will be required to answer a few safety questions when registering at the centre.

Join us for a scenic and peaceful adventure through the countryside north of Wickford, where quiet woodlands, farmland paths, and the tranquil waters of Hanningfield Reservoir combine into a perfect winter escape. This circular route winds through open fields, hedgerow trails, and rural lanes before meeting the edge of the famous Hanningfield Reservoir nature reserve — a haven for winter birdlife and sweeping water views. Expect varied terrain, gentle rolling hills and wide Essex skies. Start/Finish: Wickford Station Distance: 18.5 km Time: Approx. 6 hrs including breaks Total Ascent: 155 m Grade: 2.5 – Moderate–Challenging Meet: 9:00 am Start: 9:15 am Finish: \~3.15pm From Wickford, we follow country lanes and permissive paths through historic Downham and the surrounding farmland. As we loop north, glimpses of the reservoir appear through trees before we reach the southern shoreline, where birds, water views and peaceful wood edges take centre stage. The return route offers more variety—past small farms, tucked-away woodland strips and gently undulating countryside—before bringing us back into Wickford. A brilliant longer day out for those looking for mileage, landscapes, and the calm beauty of rural Essex.

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.

It's Herschel's birthday (1792). Not William, who discovered Uranus & various moons around it and Saturn, or Caroline who found a few comets. John, continuing the family work completed mapping of the Southern Hemisphere sky, and named the discovered moons - in Saturn's case, after Titans in Greek mythology. First stop along this Wealden walk will be his home at The Moor, a quintessential English village complete with green where cricket was played in Herschel's day, church, and the Eight Bells. The church houses a very unusual relic, delivered in 1944. Next in our orbit is Bewl Water, the largest stretch of water in SE England, described as unlike anywhere else. [Bewl Water - The Ultimate Destination for a Family Day Out](https://www.bewlwater.co.uk/) Final stop is Ticehurst, with chocolate box cottages. Further details: [Best places to live: Ticehurst, Sussex | Muddy Stilettos | Muddy Stilettos](https://sussex.muddystilettos.co.uk/best-places-to-live/sussex/best-places-to-live-ticehurst/) And when taking photographs along the walk - who coined the word 'photography' which he helped develop? Yep, John Herschel. Outward Travel: Take the train departing 9.24 AM from London Bridge to ETCHINGHAM. The return train fare with a Network Card or GroupSave is £17.00. Gather outside the ticket office at London Bridge to arrange group tickets. Walk start: 10.31 AM from Etchingham rail station. Bring a packed lunch. Village / pub stops.

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.
