Hi folks! Welcome to our March Cloud Native London meetup! Join us to hear from our three great speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube! 6:00 Pizza and drinks 6:30 Welcome 6:45 Predictable Systems in an Unpredictable World (Behrad Babaee, Aerospike) 7:15 Observability with HAProxy: detecting what is not working and why (Baptiste Assmann, HAProxy Technologies) 7:45 Break 8:00 eBPF: Revolutionizing Cloud-Native Security (Alam Ahmed) 8:30 Wrap up See you there! Cheryl (@oicheryl) **Predictable Systems in an Unpredictable World (Behrad Babaee, Aerospike)** Modern systems are challenged by volatility. Traffic patterns shift without warning, workloads evolve continuously, and failures are no longer exceptional events. In this environment, average performance is meaningless. What matters is whether systems behave predictably when conditions change. This session explores how system design choices determine behavior under volatility. We will discuss why many modern architectures rely on fragile assumptions about steady-state workloads, cache locality, or predictable growth, and how those assumptions break down in real production environments. Through concrete examples and architectural discussion, we will examine what it means to design systems that remain predictable as load, access patterns, and scale evolve. The goal is not to showcase tools or benchmarks, but to build a shared mental model for thinking about predictability as a first-class system property. *Behrad Babaee is a software engineer who leads Product Marketing at Aerospike, shaping positioning and go-to-market strategy for real-time data systems in the AI era.* *He began his career building scalable, distributed applications for organisations including Barclays and Credit Suisse, before moving into architecture and field leadership roles at Aerospike and DataStax.* *Today, he combines deep engineering expertise with strategic product leadership, focusing on how organisations design systems that remain predictable, resilient and performant under real-world volatility.* **Observability with HAProxy: detecting what is not working and why (Baptiste Assmann, HAProxy Technologies)** Is it the network, the app, or the database? In complex microservices environments, "mean time to innocence" is a critical metric for platform engineers. HAProxy sits at the convergence of these traffic flows, providing a unique vantage point to answer the ultimate observability question: "WTF is going on?". We'll do a deep dive into the metrics that matter, so you can detect anomalies before users complain. You will learn: * The difference between monitoring and observability in a reverse proxy context. * How to access HAProxy’s detailed logs, stats, and stick-tables. * How to analyze the "life of a request" using precise timers to pinpoint latency sources. * How to use HAProxy’s observability features to fix real-world issues (demo) * How HAProxy Fusion provides centralized observability and automation for enterprise deployments at scale. *Baptiste Assmann is Director of Product at HAProxy Technlogoes. He spent his carreer on networking and high performance architecture. Today, he plays a key role on HAProxy's ecosystem evolution: from bare metal to Kubernetes and from load balancing to advanced security at scale and always looking forward for what's next!* **eBPF: Revolutionizing Cloud-Native Security (Alam Ahmed)** eBPF: Revolutionizing Cloud-Native Security from the Kernel Up Cloud-native architectures have fundamentally broken traditional security models. While 67% of organizations now delay deployments due to Kubernetes security concerns, conventional tools remain blind to the dynamic, ephemeral nature of containers—operating from the outside looking in, missing critical kernel-level threats until it's too late. This session reveals how eBPF (extended Berkeley Packet Filter) is transforming cloud-native security by moving visibility and enforcement directly into the Linux kernel. Through real-world case studies from Meta, Google, and Cloudflare—where eBPF processes billions of packets per second and mitigates multi-terabit DDoS attacks—you'll discover how this technology delivers 10x performance improvements with <1% CPU overhead. We'll explore the production-ready CNCF ecosystem (Falco, Tetragon, Cilium) and demonstrate practical security observability patterns: process execution monitoring, network correlation with Kubernetes context, file integrity tracking, and syscall anomaly detection. No kernel modules. No code changes. Complete visibility. Whether you're battling container escapes, cryptojacking, or compliance gaps, this talk provides the architectural blueprint for security that matches the speed and scale of cloud-native—without sacrificing agility. *Alam Ahmed is a Junior Cloud & DevOps Engineer with NOC operations experience and a focus on cloud security. He has spoken at Elastic London and Yorkshire DevOps on Security as Code practices, contributes to open-source projects including Envoy AI Gateway, and is passionate about kernel-level observability and cloud-native defense.* ***Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.***

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.

Hey! Please join us for our Saturday evening Meetup at Picturehouse. Come and hopefully have a little bit of quiet sanctuary with us - the venue usually thins out as the evening goes along - last time we ended up being the last ones there. Recently we've been setting themes for the Meetups. I saw this short video recently about INFJs and long distance relationships and it made me wonder if INFJs tend to have an avoidant attachment style (which I certainly have had in the past and distance - physical or emotional - is a big factor in that). There are mixed opinions about it online - perfect for a discussion! It also links back to the discussion about being an INFJ possibly coming from trauma - we usually have lively discussions about that too. So bring your opinions and an open mind and we can see what we can learn from each other. [https://youtube.com/shorts/O40DXQ52FDc?si=mVfvu9QpVzaCv2mi](https://youtube.com/shorts/O40DXQ52FDc?si=mVfvu9QpVzaCv2mi) Please note you don't have to be well-versed in Myers-Briggs Type Indicator to attend; we are merely looking to build a community of like-minded people for fun, support and connection. We'll meet on the 1st Floor of Picturehouse Central (Piccadilly Circus). If you turn right at the top of the stairs and head towards the screens, there's an area on the right-hand side which is quieter than the main bar hopefully we'll get a space there, although we'll comment on the day. We'll have an INFJ sign on the table. Please note, the last couple of times, it wasn't possible to buy alcoholic drinks without a cinema ticket - only soft drinks, or tea/coffee at the bar. There's always some people who don't come on the day, so if you're top of the waitlist, or would just really like to come, please come anyway - last time we took over the entire curtained area. We're really going to try hard this year to find our own private venue and to open up numbers more.

## \*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!

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.

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.

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

**Understanding the Columbus Housing Market: Let’s Talk Downsizing for Seniors** Understanding the Market to Make Your Best Move Yet Thinking about downsizing or helping a parent prepare for a move? Join us for a friendly, educational seminar designed specifically for seniors in Central Ohio. We’ll break down what’s happening in today’s Columbus housing market, explore timing and planning for downsizing, and discuss easy ways to prepare a longtime home for sale—without overwhelm. You’ll also learn about low‑maintenance housing options, financial considerations, and simple steps to make your next move smooth and stress‑free. This is a relaxed, no‑pressure event where you can ask questions and get practical advice tailored to seniors and their families. Hosted by: Katie McCartney, Broker & Senior Real Estate Specialist® (SRES)

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)

We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.
