Error-handling in C++26
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*
\-\-\-

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)

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.*

**Main Talks**
1. **Agentic Workflows for Data Engineers: How AI Agents Are Changing Our Daily Work** - [Yusuf Ganiyu](airscholar@gmail.com)
Last month, I debugged a critical pipeline failure in 4 minutes that used to take 30. The difference? An AI agent that understands my data infrastructure.
This isn't about replacing data engineers, it's about eliminating the toil that keeps us from high-value work. In this talk, I'll share practical experiments with agentic workflows from my work at AstraZeneca and teaching 20,000+ students at DataMasteryLab.
We'll explore:
* What agentic workflows actually are (beyond the hype)
* Live demo: AI-assisted pipeline debugging with LangGraph
* Practical patterns: Schema evolution, data quality monitoring, self-healing pipelines
* The feature engineering bridge: Helping data scientists love you
* What AI still can't do (and why that matters)
Whether you're skeptical about AI hype or already experimenting, you'll leave with concrete patterns you can implement in your pipelines next week.
2. **Explore the Kingdom - Cursor the Data Engineer** - [Jethro Reeve](jethro.reeve@gmail.com)
I built [explorethekingdom.co.uk](http://explorethekingdom.co.uk/ "http://explorethekingdom.co.uk") over Christmas using Cursor with Opus-4.5 and GPT-5.2 for the data engineering and UI.
I've pulled \~15 Government data sources and have them represented on a map of the UK. This kind of data aggregation tool sells for thousands to niche consultancies. I built it while playing Minecraft on Boxing Day.
What would you use it for? (Why) Is the software world so slow to catch up with the capabilities of vibe coding?
**Lightning Talks**
1. **Github Codespaces for Data Analysis with Python - [Stelios Christodoulou](stelios.xristodoulou@gmail.com)**

Confidence in Bloom: How Creativity Builds Confidence
**Confidence in Bloom: How Creativity Builds Confidence**
What happens when creativity becomes an intentional practice?
In this month’s Confidence Lab, we’ll gather at **Petals That Inspire: The Flourish Studio** for an evening exploring the connection between creativity and confidence. How making with our hands, engaging our senses, and allowing space for expression can shift how we see ourselves and what we believe is possible.
Our featured speaker, **Amanda Lorenzetti**, owner of Petals That Inspire, will share how creativity has shaped her own confidence journey and why creative environments play such a powerful role in well-being, resilience, and personal growth. Drawing from her work leading an experience-driven floral studio and a community-centered workforce development program, Amanda will reflect on creativity as both a personal and collective catalyst.
Amanda will also guide us through a **hands-on floral design experience**, creating a fresh arrangement in a wide mouth mason jar. No prior floral experience is needed, just curiosity and a willingness to engage the process.
This evening is an invitation to slow down, create, and reconnect with the part of yourself that grows through care, attention, and imagination. You’ll leave with a floral arrangement to take home, and a deeper understanding of how confidence can be cultivated through creative practices.
**Featured Speaker: Amanda Lorenzetti**
Amanda Lorenzetti is the owner and founder of [Petals That Inspire](https://www.petalsthatinspire.com/) and The Flourish Studio, a social enterprise florist based in Columbus, Ohio. She brings more than a decade of experience in wedding and event sales, paired with hands-on expertise in floral and event design.
Amanda’s connection to the floral industry began early, spending time alongside her godmother, a professional florist on the East Coast.
After earning her business degree, she returned to her hometown in Connecticut to work as a floral and event designer, blending creative artistry with strong operational and client-focused skills.
In 2020, Amanda returned to the floral industry with a renewed purpose, driven by a desire to build a business rooted in creativity, community impact, and sustainability. During this pivotal time, she founded Petals That Inspire—an innovative floral concept that reimagines the traditional florist model by combining event florals, workshops, and experiential offerings with a mission-centered approach to workforce development.
Today, Petals That Inspire is a thriving social enterprise known for its thoughtful design, educational experiences, and commitment to empowering young adults facing barriers to entry in the workforce. Amanda is deeply passionate about building businesses that are both profitable and purpose-driven, and she leverages her strong business acumen to create a scalable & sustainable model that inspires creativity while giving back to the community.
**What is Confidence Lab?**
Confidence Lab is a monthly community experience for bold, thoughtful leaders building confidence from the inside out. Whether you’re launching a business, leading a team, navigating change, or simply striving to show up more fully—you belong here.
Our work demands clarity, courage, and conviction—but the pace of daily life can erode our sense of self. Confidence Lab creates space to reflect, reconnect, and grow with others doing purpose-driven work.
It’s designed for entrepreneurs, nonprofit leaders, creatives, corporate professionals, activists, and anyone ready to lead with authenticity and impact.
