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). Talks start at **7:00 pm**, with drinks afterwards from **9:00 pm** at The Banker (EC4). We have reduced capacity for this event, but there will be plenty of people to discuss data science questions with. Please unRSVP in good time if you realise you can't make it. We're limited by building security on the number of attendees, so please free up your place for your fellow community members. If you want me to trim lightning talks down to two or shorten any abstracts, say which ones.

**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 London’s #1 dating events team and 30 outgoing, single guests for an action-packed evening of speed dating in a classy Kings Cross venue. Just moments from King’s Cross and St Pancras stations, Drake & Morgan is a trendy, contemporary bar spread over two floors with a lively, eclectic crowd. Guests at this popular speed dating event will enjoy a large, private area as they meet each of their 15 dates. Plus, a fun and friendly *It’s a Date* host will keep the social energy flowing — we think this might just be the best speed dating event north of the river! Our host will be at the venue ready to welcome you at 19:30. Please arrive on time for registration, grab any drinks from the bar, and receive a summary of how things will work. You will be given an optional name sticker, a pen, and a note card to keep track of everyone you’ve met. Ladies will be seated on tables adequately spaced, discreetly numbered, and arranged in a comfortable area of the venue. When speed dating commences, gents will join ladies for 5-minute dates to get to know one another. Your host will notify all guests at the end of each date, signalling for gents to move to the next table in ascending numerical order. During table rotations, you will have a moment to record on note cards your feelings towards the previous date and intention to reconnect, for your reference only. Mid-way through the evening, your host will indicate a 15-minute comfort break to use the rest room, head to the bar, or socialise with new connections. Dating will then resume for the second half of the evening. At the end of the speed dating the bar will remain open for more socialising. You can then access the event listing in your dashboard to enter feedback on dates and await your matches. If you have any questions on the event or how things will work, please get in contact with James on 07517 065 492 or [james@itsadate.club](mailto:james@itsadate.club).

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.

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.**

For our next meetup we’ll be exploring a couple of different aspects of football analysis. We’ll start with a quick warm-up discussion: **“Useful stat or overrated stat?”**. Bring along a football metric you think is either particularly valuable or perhaps a little overused, and we’ll go around the table to hear a few perspectives. Next, we’ll move into a short **Tactical Breakdown** section. If you’d like to contribute, bring along **one interesting tactical idea** from a team you’ve watched recently. You might cover: • The team and situation (e.g. build-up, pressing, chance creation) • What the pattern or idea looks like • Why you think it works (or doesn’t) Finally, we’ll finish with some **Hidden Gem scouting**. If you’d like, bring along **one player you think could soon make the jump to a bigger league**. A few things you might mention: • Who they are and where they play • What they’re particularly good at • A stat or observation that supports it • A club they might fit at As always, the aim is to share ideas, hear different approaches to analysis, and enjoy talking football. **Location TBC**

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

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.

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)
