**A software engineers guide to LLMs** In this talk Richard Conway will break down what LLMs are layer by layer, how they work, how they use software principles to work and how to use them in software. This will be a fluid talk with a lot of philosophy, maths from school and how to build your software understanding things like hallucinations and new techniques that can make your management of LLMs more deterministic. We'll consider a lot of things here including the new code generation tools which have developers quivering in their boots, what they mean for our industry and how to use them for effect. Lots of mini-demos and great discussions, good people, beer and pizza! **About the speaker** Richard Conway co-founded the user group, along with Andy Cross, Joe Hancock and Chris Parsons. He is a Microsoft AI MVP and a Microsoft Regional Director and has been writing software in one form or another since his fingers were large enough to hit a ZX81 keyboard.

**Join us for a joint meetup with our friends from Qodo and Tessl** AI coding agents are increasingly embedded in production workflows, but their failure modes are often poorly understood, difficult to detect, and even harder to evaluate systematically. ​This session examines how agent-based systems degrade under real-world conditions, focusing on three critical dimensions: reliability, code quality, and security. We’ll look at where current evaluation approaches fall short, how non-determinism and context drift impact correctness, and why seemingly “successful” generations can still introduce latent defects or vulnerabilities. ​If you’re building, evaluating, or deploying AI agents in production systems, this session will provide a grounded view of where they fail and what it takes to make them robust **Agenda** * ​​​6:00pm Venue opens * ​Join us for Drinks and Pizza! * ​​​6:30pm **Hidden Failure Modes for AI Agents** by Nupur Sharma * ​6:50pm Panel Discussion * ​**Panelists** * ​**Simon Maple -** Developer Relations at Tessl * ​**Brian Vermeer** \- Staff Developer Advocate at Snyk * ​**Nupur Sharma -** Solutions Engineer at Qodo * ​**Kunal Kushwaha -** Senior Developer Advocate EMEA at Cast AI **SPEAKERS** **​** **Simon Maple - Developer Relations at Tessl** ​Simon Maple is the Head of Developer Relations at Tessl, and AI Native Dev co-host.

Elixir London Meetup; February 2026 edition. All are welcome. **Session 1: Anton Borisov - Distilling Kafka's Binary Protocol into Elixir** We'll trace a produce request to show what any Kafka client has to get right. In the BEAM ecosystem, erlkaf wraps librdkafka, brod implements the protocol in Erlang, and [kafka_ex](https://hex.pm/packages/kafka_ex) goes pure Elixir. Kafka_ex's approach is to generate serializers at compile time from Kafka's own schema definitions: plain structs, pattern matching, structural boilerplate isolated from the logic you actually think about. That design is what let us jump two major versions ahead and adapt to significant protocol changes. Let's dig into the idea, the code, and the tradeoffs. **Session 2: Evadne Wu** **\- JavaScript Execution Strategies in Elixir\-based Agent Frameworks** We'll look at integration points between elixir agents (in the AI fashion) and JavaScript execution, and all the foot guns involved. *The event is kindly sponsored by* [Fresha](https://www.fresha.com). **Time** Doors open at 18, start at 18.30. **Venue** Fresha The Bower, 207-211, Old St, Tower, London EC1V 9NR **Refreshments** Food and drinks will be provisioned on the day. **IMPORTANT**: **If you wish to take photos and post online during the event, please notify organisers first, so that attendees can opt-out from being in photos.**

Agents are writing code, running workflows, and building other agents. ​ The challenge isn’t basic functionality. It’s getting these systems to operate predictably in production, and integrating them into how teams build and ship software. ​This session covers both. ​ From a production lens: how to build agentic systems using spec-driven development, structured context, and evaluation loops that hold up at scale. ​From a human lens: what breaks when agents become collaborators. Ownership, coordination, and how teams actually adapt. ​Speakers: ​**Clifton Cunningham** ​**Member of Technical Staff, [guidemode.dev](https://guidemode.dev/?utm_source=luma) \| Former CTO at DailyMail\, Infinitas Learning\, TES Global** ​Clifton will explore what happens when AI agents become part of your team. Drawing on experience leading large-scale engineering organisations, he’ll unpack the human, cultural, and operational challenges of working alongside AI colleagues. ​**Alfonso Graziano** ​**AI Tech Lead\, Nearform \| Author of *AI-Native Software Engineering*** ​Alfonso will walk through how to build agents that build and maintain other agents. A practical, production-focused session covering spec-driven development, context engineering, evaluation loops, and how to make agentic systems reliable at scale. ​ Join us for pizza, drinks, and practical AI insights.

We are back! This is going to be a monthly IN PERSON meet up in London. A very big thank you goes to Accurx who is hosting us in their amazing Shoreditch offices. This will include access to facilities including coffee! 😻☕️ **Want to know more? 👇** As with all CoffeeOps, this is an interactive, chatty, build your own adventure type of meet-up. Instead of booking in experts to *learn* *from*, we gather a group of practitioners to ***learn*** ***with***. We have been running for over 4 years now and often get feedback that this is the most useful meetup people join! The event is approximately 90 minutes and always starts by brainstorming topics to discuss. The group then votes on the most relevant/interesting to them and we then cycle through the topics trying to discuss each deeply, but in a time bound slot. To get an idea of topics, you can check out our remote board [here](https://easyretro.io/publicboard/h404NF84Uje4tCcxpJdHr4Ycs9B3/a4a35d2b-181b-409b-832e-a729be1af79c). The general gist is anything is fair game, though we tend to revolve around software delivery and definitely lean towards the more Ops-y or DevOps-y side of things.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
