Happy 2026! Our first meetup of the year will be back at Zühlke's offices near Old Street, with Guillaume Faas talking about better ways to handle exceptions, Jenny Martin talking about taming complexity with OOPSI, plus the usual drinks, snacks, and plenty of time to chat. Doors 18:30, the first talk starts at 19:00 and we'll be done and heading to the pub at 21:00 to continue the conversation. **Guillaume Faas: Throw exceptions... out of your codebase** Throwing exceptions is often used to handle errors, validations, and other specific use cases. It is considered by many to be the standard way of indicating a failure and providing feedback to the caller. However, this approach can cause significant issues like being hard to detect, obfuscating the flow or leaving the system invalid. In this talk, I want to show you a faster alternative that offers more transparency and predictability. We will see how to integrate ideas from the Functional paradigm, such as "Monads", into an Object-Oriented codebase using a real-life project: Vonage's open-source .NET SDK. This talk will be the perfect opportunity to show you what they are and how easy they are to use. **Guillaume Faas** is a Senior .Net Developer Advocate at Vonage, based in Thionville, France. In recent years, Guillaume has focused on sharing my experience through mentoring, public speaking, and open-source contributions; all aimed at helping teams grow and build sustainable software. With nearly 15 years of experience in .NET development, he's worked across industries as an engineer, coach, and now developer advocate. His current focus is on developer experience: building SDKs, writing approachable technical content, and speaking at conferences around the world. **Jenny Martin: OOPSI: Making Sense of Complexity** OOPSI stands for outcomes, outputs, process, scenarios, inputs. It’s a flexible, easy-to-use collaboration framework that helps agile and product development teams cut through complexity and focus on value. OOPSI is timely because it maximises the intrinsically human aspects of effective delivery, helping teams understand how and when to collaborate, while producing lean, example-driven artefacts that clarify scope and intent so both people and automation can work more effectively. In this talk, you’ll learn how to apply OOPSI to strengthen shared understanding, clarify assumptions, and support testable delivery, using a detailed, end-to-end example. **Jenny Martin** is a practitioner, facilitator, and product discovery specialist with over 25 years’ experience working at the intersection of technology, delivery, and human behaviour. She has spent more than 15 years working with Agile and modern product development teams, helping them make sense of complexity and build shared understanding. Known as The Collaboration Coach, Jenny focuses on practical collaboration that supports effective delivery. She is currently writing a book on OOPSI.

London TypeScript is back! We’re kicking things off with a smaller, more relaxed social before announcing our first major event of 2026. Four Quarters is a great chain of retro arcade bars, with plenty of classic games and a laid-back atmosphere. Come along to play a few games, meet some fellow TypeScript fans, and most importantly, share your ideas and suggestions for the future of London TypeScript.

Join us at our next Emacs London meetup held at University College London (UCL) on Tuesday 24 February. A projector will be available, if anyone wants to give a presentation and/or if helpful to share Emacs tips, for some collaborative debugging, etc. We might head to a pub for a drink and/or a nibble afterward. Emacs users of all levels welcome! Interested in Emacs but not really a user? You're more than welcome too! **Call for presentations** Fancy talking about your favourite Emacs package? Proud of your latest Emacs Lisp hack and you want to tell everybody? Anything parenthesis-related that's bugging you? There'll be a monitor waiting for you for a short presentation!

We're welcoming back the legend that is Dave Whitney after a covid time lapse of years. Your chance to catch one of the best tech speakers in the UK software community! \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- It's a tough time to be a technology professional. We're simultaneously being told that AI will change everything we know about the world, while simultaneously being told that the bubble is going to burst. Everyone is going to be redundant! AI will fail! AI will ruin the internet! AI can't do anything! It's disorienting and stressful trying to work out what a reasonable strategy should be to move forwards with this technology that appears to shift it's goalposts almost daily. In this session, we'll talk about understanding what AI really is, how to form a reasonable, governance friendly strategy around it, and what the sensible bets for the future are in the space. We'll do a deep dive into ethics, the human cost of content moderation, and having to be confronted by the reality of technical change in real-time. A survival guide to getting the most from the most controversial technology in a decade. An AI moderates warts and all deep dive into surviving as technology changes, without giving in to the hype during times of technology innovation and change.

# ​Beginners Hands-On Workshop: Demystifying OpenClaw, the New Personal AI Everyone's Talking About: The Good, The Bad & The Sloppy **Registration to this event is only valid through the Luma platform: [https://luma.com/wy7xdrca?utm_source=meetup-dot-com](https://luma.com/wy7xdrca?utm_source=meetup-dot-com)** Hello everyone! Due to popular demand we are going to run a full OpenClaw (previously known as Clawdbot/Moltbot) event! Join us on **Thursday, 26 Feb**. This would be our 5th event in our series of **local-first, open-source** **AIs** therefore we will try our best to avoid connecting OpenClaw to any cloud-based AI model and keep everything private. We will focus on the good (useful ways of automating things with it), the bad (the rough edges of OpenClaw, security wise) and the sloppy (the danger of creating too much low-quality content especially since the Internet is full of that type of content). This workshop is open to all levels, from beginners to experts. Bring your laptop (make sure it's fully charged if possible as local LLMs tend to be power-hungry), and, don't forget to bring your coding gear (hoodie). We will try to run A.I. models on the mobile phone as well so feel free to bring your phone fully charged with a little bit of free storage space. This workshop will be accompanied by Sam W. & Joon-sang L. (the founders of Pentaform). Since the recommended way to run OpenClaw is on its own dedicated hardware and since there are people at Encode specialised in building mini-PCs, what better way to close the night than to hear about various hardware options and to see what Pentaform is building. See you there! *** ## Prerequisite First and foremost\*\*, VERY IMPORTANT\*\*, a VM (Virtual Machine) system like Docker/UTM for MacOs or WSL for Windows. Lastly, a local install of Ollama / LMStudio (but if you don't have any of that, don't worry, come a bit early and we will help set you up). Ideally you should check the slides from the previous event to set up Ollama locally: [https://andysign.github.io/ai-london-01/](https://andysign.github.io/ai-london-01/) Not related but still interesting, the second slide deck about flows with LangFlow (you should know how to access it if you've been to the last workshop, if not join the Discord and ask us): [https://andysign.github.io/ai-london-02/](https://andysign.github.io/ai-london-02/) There is a third deck, also not related (about personal RAGs w/ AnythingLLM): [https://andysign.github.io/ai-london-03/](https://andysign.github.io/ai-london-03/) And a forth deck, this one is slightly related (about AI-powered browsers): [https://andysign.github.io/ai-london-04/](https://andysign.github.io/ai-london-04/) *** ## Agenda for the evening (Subject to change) **18:00 - 18:30 Arrival and networking** Mingle with fellow developers over refreshments. **18:30 - 18:45 Introductions (What is Local-First?)** Learn about self-hosted, local AI models and why we use them. **18:45 - 19:40 Workshop** ​Hands-on technical workshop (if you are non-technical it's OK, tag along). **19:40 - 20:15 Pentaform and Local AI** **20:15 - 21:00 Networking** **21:00 - Closing remarks and follow-up** **END:** Carry on the fun at a nearby pub which is right around the corner. *** ## Event Venue We'd like to extend a heartfelt thank you to **Encode Club**. [Encode Club ](http://encode.club)has spent over five years fostering a global community of developers, researchers, and founders in Web3, AI, and emerging technologies. The [Encode Hub](http://hub.encode.club) brings everything together under one roof, providing a dedicated environment for collaboration and innovation through meetups, co-working, and in-person events. *** ##

**Please register on [Eventbrite](https://www.eventbrite.co.uk/e/ljc-meetup-at-capital-one-tickets-1981939102207) to join this event.** **About this event** LJC Meet-ups is a new series of events, aimed at giving all Community members an opportunity to present at an LJC event. Join us on 26th February 2026 for a London Java Community meetup hosted at Capital One. This event brings together practitioners exploring what it means to build modern, cloud‑native platforms and work effectively with AI‑powered development tools. As cloud adoption matures and AI coding agents become embedded in engineering workflows, this evening focuses on two critical themes: architecting for cloud‑native efficiency and leveraging AI agents more effectively in real‑world development. **Talk 1 – Tom Clifford‑Clarke, Lead Software Development Engineer at Capital One** *Keeping our heads in the cloud, using AI agents on the ground* Many organisations operate entirely in the cloud — but far fewer are truly cloud‑native. As architectures evolve and AI becomes a core concern, the gap between “running in the cloud” and “optimising for it” becomes increasingly costly. Tom explores why robust architectural patterns and standards are non‑negotiable today. Drawing on Capital One’s journey, he’ll cover practical approaches to Event‑Driven Architecture, serverless adoption, and service cataloguing strategies that unlock scalability, efficiency, and AI readiness — while improving the developer experience. **Talk 2 – Steve Poole, Community Director at LJC** *AI-Assisted Development and the New Risk Surface* AI-assisted coding is now a standard part of development. It accelerates delivery and reduces friction, but it also changes how risk enters our codebases. AI models replicate patterns at scale, including insecure defaults, outdated practices, and subtle flaws. In some cases, attackers can influence public training data or open-source projects, allowing weaknesses to spread quietly through tools and libraries developers trust. This talk looks at how AI-generated code fits into the modern software supply chain, and how speed, automation, and trust can be exploited. We'll examine how vulnerabilities slip past reviews, why unvetted AI output can bypass safeguards, and what these failures look like in real systems. With real-world examples, we'll focus on practical ways to review, test, and integrate AI-generated code responsibly. Strengthening your workflow instead of undermining it. AI isn't the problem. Unexamined automation is. The goal is not fear, but sharper judgment about when AI is helping, and when it needs a closer look. **Speaker Bios** **Tom Clifford‑Clarke** Lead Software Development Engineer at Capital One. Tom’s background spans large‑scale corporate software, end‑user products, and custom delivery tooling. He now focuses on cloud productivity engineering — improving developer experience and enabling teams to build high‑quality software at a sustainable pace.

## DevOps Society Meetup with EDF **Location:** EDF UK, Nova North, 11 Bressenden Place London, SW1E 5BY **Time:** Doors open at 6PM **Drinks, snacks, talks, and networking.** We’re excited to invite you to our first in-person **DevOps Society Meetup** of 2026, proudly **sponsored by EDF**. This event brings together the DevOps, SRE, and cloud engineering community for an evening of honest conversations, real-world lessons, and networking with people who’ve actually done the work. A huge thank you to **EDF** for sponsoring the event and for providing the venue, refreshments, and support for our community. *** ## ️ Format of the Meetup: 6:00pm – 6:30pm — Networking on arrival, with food and drinks provided by EDF 6:30pm – 7:10pm — First speaker + Q&A 7:10pm – 7:20pm — Break for refreshments and networking 7:20pm – 8:00pm — Second speaker + Q&A 8:00pm onwards — More networking at the venue, then at a nearby pub. *Timings can vary slightly depending on Q&A.* *** We’re delighted to welcome **two fantastic speakers** to this EDF-hosted DevOps Society meetup. *** ## SPEAKER 1 – Steve Bowerman **Principal Software Engineer, EDF** ### Bio Steve is a technologist and thought leader with **25 years in the industry**, including **20 years in the utilities sector**, spanning startups through to large, established enterprises. Since stepping into the role of **Principal Software Engineer at EDF**, Steve has played a key role in reviewing and overhauling EDF’s approach to software engineering - bringing critical capabilities in-house and aligning teams with modern **DevOps and SRE principles**. His work focuses on long-term, sustainable transformation rather than tooling churn, helping large organisations evolve how they build, operate, and scale software. *** ### Talk Title **Rebooting the Enterprise: The DevOps Way** ### Talk Intro Building a DevOps mindset in a startup is relatively easy - it’s often the default DNA of modern engineering teams. Doing the same in a **large enterprise** is a very different challenge. In this talk, Steve will take you through **five years of transformation in 15 minutes**. He’ll share how EDF approached enterprise DevOps adoption, where things failed (and why), what ultimately worked, and the lessons learned along the way. Spoiler: **technology was the least difficult part**. This session is ideal for engineers, platform teams, and leaders working in complex organisations who want a realistic view of what enterprise DevOps transformation actually looks like. *** ## SPEAKER 2 – Matteo Emili **Director of Software Engineering, Avanade** **Bio** Matteo Emili is a Director of Software Engineering at Avanade UK and Ireland, leading the talent in Software Engineering and always looking at new ways of applying technology to solve business problems. He is a passionate Agile advocate and a technologist at heart, a Cloud Architect who is always driven by using technology as a vehicle for change and continuous improvement. A Microsoft MVP since 2010 (currently in the Azure DevOps and GitHub category), he enjoys sharing back as much as he can with the worldwide technical communities – especially within Agile and DevOps. He has founded several User Groups around Europe and he is a regular speaker at meetups and conferences. ### Talk Title **From Vibe Coding to Agentic Engineering: A Step-by-Step Guide** ### Talk Bio AI-augmented software development is evolving. What started as *“vibe coding”* \- intuition\-driven\, creative experimentation with AI \- is now moving toward **agentic engineering**, a more governed and intentional approach where AI agents actively collaborate with developers while enforcing best practices and organisational standards. In this session, Matteo explores how teams can transition from unstructured AI experimentation to **agentic workflows** that balance creativity with accountability. You’ll learn how agentic engineering enables: * Faster development without sacrificing quality * Built-in governance and standards * AI collaboration that scales across teams * A practical path from experimentation to production-ready AI-assisted engineering This talk offers a clear, pragmatic view of how AI will reshape software engineering in the years ahead - and how teams can adopt it responsibly. *** Please **RSVP to secure your spot**. Spaces are limited and available on a **first-come, first-served** basis. We’re really looking forward to getting the community back together again for our first event of 2026.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. 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.

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.
