**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.

***The Fitzroy Tavern Edition*** ALTERNATIVE PLATFORM FOR BOOKINGS: **EVENTBRITE** (link below) Start your public speaking journey with us. Like a lot of people, we’ve had our own battles with public speaking. That’s exactly why this group exists. It’s for anyone who wants a place to start, people who want to keep practising, and those who just need a friendly audience to try things out. We grow at our own pace and build confidence in a relaxed, safe and supportive space. You’ll meet like-minded people, make new connections, and steadily get more comfortable speaking in front of others. There’s no judgement here. It’s just space for people to be themselves. We know there’s no single “right” way to speak in public. Whether you’re prepping for presentations, interviews, a best man speech, handling social situations, or simply getting more comfortable saying what you think, you’re welcome to explore your own style and find what feels natural to you here. PS Free event. Groups are kept small so everyone gets plenty of stage time, usually no more than 10–15 people. The pub kindly lets us use their space, so if you fancy it, feel free to grab a drink (or just a soft drink ) while you’re here. It’s a nice way to say thanks and helps us keep the space for future sessions.

This talk introduces the core principles of federation and why it matters for modern OLAP workloads. Using StarRocks as a model system, we highlight its vectorised execution engine, native connectors, and deep Apache Iceberg integration that together deliver high-performance lakehouse querying. 2. [Ben Guerin](https://www.linkedin.com/in/bjhguerin/) **How I Learned to Stop Worrying and Let Claude Code Write the Python [the story of [ismypubfucked.com](http://ismypubfucked.com/ "http://ismypubfucked.com")]** 43,000 pubs. Official VOA data. One question. [ismypubfucked.com](http://ismypubfucked.com/ "http://ismypubfucked.com") got 400k visits in two weeks and wall-to-wall media coverage: from the Mirror to the Telegraph to City AM. I'm not a Python developer. I used Claude Code to wrangle government spreadsheets, match them to OpenStreetMap, and ship a working site. All in less than 6 hours from initial idea to a live website. The AI wrote the Python, I just knew what story the data could tell. This talk covers what happens when tools like Claude Code unlock Python for people who think in narratives rather than syntax, and what a decade of building viral campaigns has taught me about making people actually give a shit about spreadsheets. **Lightning Talks** 1. **TBC** 2. **TBC** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Logistics** Doors open at **6.30 pm** (get there early as you'll need to sign in with building security).

**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.**

**Explore AI over dinner at a Michelin-listed London restaurant. Tools, opportunities and real conversation.** Each Meet2Click Curated Conversation dinner centres around a carefully chosen topic or shared interest, designed to spark thoughtful conversation and meaningful connection. **Curious about how AI is changing our lives — and want to explore it in a relaxed dinner setting?** Artificial Intelligence is evolving rapidly. New tools, ideas, and breakthroughs are reshaping how we work, create, and think. Instead of abstract debate, this evening is about sharing what we’re discovering in real life. Two days before the dinner, guests will receive a short, accessible overview of interesting AI tools — simply to spark ideas. At the table, we’ll explore: • What AI tools have you tried recently? • What discovery or breakthrough impressed you most? • Where do you see the greatest opportunities emerging? No technical background required. **Launch Season Benefit** During our initial Meet2Click dinners, guests will enjoy **up to 50% off food** at the restaurant. This introductory benefit is available for a limited launch period. Food and drinks are paid individually, directly with the restaurant. **Details** Location: restaurant Bala Baya, Arch 25, Old Union Yard Arches 229, Union Street, London SE1 Date: 8 April 2026, 19.00h **Ticket price:** £15 per person *(includes your seat and contribution to the evening — food and drinks ordered and paid individually at the restaurant)* Seats are intentionally limited to encourage meaningful conversation and genuine connection. Just an open, relaxed exchange of ideas over dinner.

You’ll get to experience the style, exercises and atmosphere firsthand before deciding whether deeper training is right for you. The workshop stands alone - you’ll still leave with practical tools, insights and the option to practice doing some speaking (if you wish) - and if you feel drawn to continue, attendees receive an exclusive discount towards the full programme (normally £498). We always with fun, ice breaker warm-up games to ease you into the session, followed by learning some simple public speaking technique exercises and finishing with some (optional) opportunities to practice doing some impromptu speaking in front of the group. The class will also include some group discussions to learn more about why we struggle with public speaking, and what solutions we can use to help us. Our principles are grounded in authenticity. Our approach to helping people overcome their fears is done through encouraging participants to drop the personas they wear in their day-to-day lives in order to express themselves with honesty, and discover their natural speaking style. We’re big fans of embracing vulnerability and strongly believe it’s a strength, not a weakness. Only through vulnerability do we drop our guard and communicate in a way that truly connects to others. **The Session will include:** \- Why we struggle with nervousness when speaking in public \- Our approach for embracing and overcoming these feelings \- Practical techniques to help you come out of your head and speak using your intuition \- A chance to practice delivering a short impromptu speech \- And much more\! \*\*Secure tickets HERE by [signing up on our Eventbrite page](https://www.eventbrite.co.uk/e/free-public-speaking-class-in-london-tickets-151793471359)\*\* **About our teachers:** We have been running workshops since 2014. We have trained 10,000+ people. Our teachers compete in public speaking tournaments, have a mixture of traditional and improv acting training, studied various meditation and mindfulness techniques and are passionate about human psychology and behaviour. **Testimonials from past students:** "Definitely the best public speaking workshop I have been on! It’s much more than just improving your public speaking skills, it takes a deeper look into the subject, in terms of fears, and humanity.

Our society celebrates extrinsic success; confidence is presented to be smooth, slick, suave and charismatic. Because of this we neglect parts of our personality, our feelings, our idiosyncrasies, our uniqueness, our quirkiness and ultimately our vulnerability in pursuit of becoming confident, according to what society deems as confidence. However, we risk becoming ‘well-rehearsed robots’ and not sincere individuals, who aren’t afraid of expressing their humanness. Our approach offers a very non-conventional way of become an empowering and inspiring communicator. **Our Previous Brand (Public Speaking London):** **[https://www.youtube.com/watch?v=Rl7dAKFp1qs&t=98s](https://www.youtube.com/watch?v=Rl7dAKFp1qs&t=98s "https://www.youtube.com/watch?v=Rl7dAKFp1qs&t=98s")** **Contact details:** **[https://schoolofconnection.org/](https://schoolofconnection.org/ "https://schoolofconnection.org/")** Email: hello@schoolofconnection.org Phone: 020 3151 9908

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
