\#\#\#\# Step 1: TAKE THE TEST The Oxford Capacity Analysis identifies 10 vital personality traits that influence your entire future. It is a factual, scientific analysis taken from your answers, and it takes about an hour to complete. \#\#\#\# Step 2: GET YOUR RESULTS After you complete the test, your personality analysis is generated and displayed. Within minutes your analysis will highlight your strengths and weaknesses—which personality traits to take advantage of and which need help. \#\#\#\# Step 3: CONSULTATION While the analysis graph shows distinct personality traits, it is the interrelationship of these traits that provides the greater picture of your personality. We provide a complimentary consultation with one of our trained staff, who will give a detailed evaluation of your personality analysis. In this one-on-one consultation, you gain a better understanding of your personality strengths and weaknesses, and establish the recommended path to your fast and lasting success.

**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.

We playtest all sorts of games - strategic, silly, creative, or whatever. Some games are almost done. Some are very early ideas. We test anything that will fit into 90 minutes. You don't need to bring a game - we always love to have new playtesters! Please let us know in the comments when you plan to arrive/leave and whether you are bringing a game or not. This helps us to plan the day better. The schedule is: 10am onwards - gathering, chatting 11am sharp - playing for 90 min ('slot 1') 12:30ish - break for food/chat 1pm sharp - playing for 90 min ('slot 2') 2:30ish - break for food/chat 3pm sharp - playing for 90 min ('slot 3') 4:30ish - finish up Often, we might hang around afterwards, to play some already-published games. We are strict on timings, so please try to arrive a few minutes before the session to limit disruption. You can just come for part of the day if you wish. The reason we have fixed timings for the 3 'slots' is to make it easier for folk to do so. Designers of all levels of experience are welcome! But if it's your first time, we ask that you don't bring a game and just spend some time learning how the group works. The group works based on reciprocation. If you expect to test your own game, make sure stay for long enough to play other games. As a general rule of thumb, you can expect to play one of your own games every third 90-minute session. So if you stay a whole day (3 sessions), you can expect to have one session to play your game(s). A good rule of thumb is that if you come all day, you will have one 90 minute session with two other playtesters in which to test your own games. It is sometimes possible to test games with more players. If your game requires 4 or more, please note that as standard you will be allocated half of a session (45 minutes). Pre-covid, we were getting unmanageable. As a result, we may have to limit attendees. This is a free-to-use venue, and we have to be mindful that other folk want to use the same space. Please note: This is an adults only event. We look forward to seeing you!

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.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

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.
