First Wednesday of every month, upstairs at the William Morris Pub. Free entry and house drinks are half price between 6pm and 7pm. We sing three sets of eight songs, plus a few requests. We hand out chorus sheet books to all guests, and get 90% audience participation by way of them joining in singing the choruses. The pub has its own kitchen downstairs and cooks good quality reasonably priced food, which looks good and smells good, just like us. The pub is situated in picturesque Merton Abbey Mills on the River Wandle, only ten minutes walk from Colliers Wood tube station. Here is a link to a video of us performing there WM Wednesday link- Sept 2025 [https://www.youtube.com/watch?v=VQsN_BZZCEA](https://www.youtube.com/watch?v=VQsN_BZZCEA)

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.***

**Please note that this event will take place IN PERSON on Friday, 6 March, 2026 in London at 6pm London time (1pm New York time).** **In collaboration with Imperial College [MathSoc](https://imperialmathsoc.com/)!** **Full title:** Heisenberg's Backtest **Speaker:** Rob Carver **Abstract:** What is a backtest for? In fact, like electrons, backtests have two contradictory natures. Firstly, they tell how well a particular trading strategy would have done in the past. Secondly, they help you design a strategy that will perform well in the future. These are not the same thing. In this talk Rob discusses this problem and how to reconcile these two objectives. **Venue:** Huxley Building, Imperial College London, 180 Queen's Gate, South Kensington, London SW7 2AZ **Biography:** Robert Carver is an independent systematic futures trader and writer.

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.

**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)

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.

Come join us for coffee at Matari Coffee to discuss our March book, "The Enchanted Greenhouse"! Book description: Terlu Perna broke the law because she was lonely. She cast a spell and created a magically sentient spider plant. As punishment, she was turned into a wooden statue and tucked away into an alcove in the North Reading Room of the Great Library of Alyssium. This should have been the end of her story . . . Yet one day, Terlu wakes in the cold of winter on a nearly-deserted island full of hundreds of magical greenhouses. She’s starving and freezing, and the only other human on the island is a grumpy gardener. To her surprise, he offers Terlu a place to sleep, clean clothes, and freshly baked honey cakes—at least until she’s ready to sail home. But Terlu can’t return home and doesn’t want to—the greenhouses are a dream come true, each more wondrous than the next. When she learns that the magic that sustains them is failing—causing the death of everything within them—Terlu knows she must help. Even if that means breaking the law again. This time, though, she isn’t alone. Assisted by the gardener and a sentient rose, Terlu must unravel the secrets of a long-dead sorcerer if she wants to save the island—and have a fresh chance at happiness and love.
