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.***

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++.

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.

**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 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 spectacle is the existing order’s uninterrupted discourse about itself, its laudatory monologue. It is the self-portrait of power in the epoch of its totalitarian management of the conditions of existence. The fetishistic, purely objective appearance of spectacular relations conceals the fact that they are relations among men and classes: a second nature with its fatal laws seems to dominate our environment."*** **\- Guy Debord\, *The Society of the Spectacle*** Welcome back readers! By popular request, we're bringing back (for a new generation of LMRG readers) an old favourite: the always-relevant Guy Debord and his masterful *Society of the Spectacle*. We'll kick off with the first three chapters. Find the next here: https://www.marxists.org/reference/archive/debord/society.htm Often maligned as theorymaxxed nonsense but little-read, this slim volume is certainly dense with ideas - all of which carry as much relevance today as those half-forgotten postwar years when the Situationist International made its mark on the world, if not more. With the rise of the Internet and social media, the decline of literacy and the closing of the mass mind, the endless doom-loop of doomscrolling and bed-rotting, increasingly performative protest, the commodification of everything, the Epstein-approved culture war, and the theatre of spectacular cruelty that is imperialist colonial policy from Gaza to Venezuela, we really are living an age where everything that was once directly participated in has passed into representation. Every hand-grip one searches for to get some kind of grasp on the world seems to be a mirage; "participation" in anything, from politics to culture, has been reduced to fandom - limited to nothing more than expressing approval or disapproval through totally mediated social media platforms. Above it all stands an utterly corrupt, irresponsible elite class more and more transparent in how it relishes in conspiratorial play, power-games with unlimited stakes for us and no consequences for them. Such a world where power wears a shit-eating grin and keeps us off our balance by endlessly[ "flooding the zone"](https://en.wikipedia.org/wiki/Flood_the_zone) (in Steve Bannon's terms) with distractions so intricate they short-circuit the collective brain is exactly what Debord not only predicted but described in frightening detail, with more than a little bit of humour. So let's dig in and find out: just what can we do to unplug from the spectacle? Is the spectacle even un-plug-from-able? Debord haters, cope and seethe: as a much more orthodox Marxist than he ever gets credit for, there really are some strategies in here. We just need to be creative. Take care and happy reading!

## \*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!

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.

Join membersrs of the Central Ohio UX and digital design community for a casual monthly breakfast.

Sleep in on Sundays. When you've had your fill of pajama-time, roll out and have some tasty brunch with your fellow Humanists!

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

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!

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!
