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.

Many say that "dating your own race" or "racial/ethnic preference" are natural choices - but history shows how many countries tried to *stop* different races from mixing: from racial purity laws in the US and Nazi Germany, to Saudi Arabia's current ban on marrying foreigners, apartheid in South Africa, segregation and eugenics, and bans on marrying someone from a different religion. While mixing was common in ancient empires and trade routes, race is now a common "filter" in apps and dating advice. Is this really just a matter of personal taste, or is there an element of prejudice and politics? We'll discuss: 1\. Is racial preference really natural \- and why have countries tried to prohibit different races\, ethnicities and religions mixing? 2\. Do modern dating ideas on race/ethnicity/culture carry political goals\, e\.g\. racial purity\, cultural conformism\, etc? 3\. How to tell whether it's preference\, prejudice or politics\, in our daily lives? *Join us for a relaxed group conversation where we explore the real life, the grey areas, and how our different cultures and backgrounds shape our views about key topics.* *Expect real talk, no judgment, and a chance to learn how others see it.* **\*Come for the discussion, stay for the friendships. Our weekly discussion series brings together thoughtful people for honest conversations on relationships, life, and society - with warm social vibes before and after.\*** **WHAT TO EXPECT:** * Good vibes only: we chat big topics in a chill, respectful way. No arguing - just open-minded exchange. * We warm up with casual socializing (come solo or with friends!) * The topic starts around 7:45/8pm, wraps around 9:30. * 🍕 There's pizza, drinks, milkshakes and snacks available at the bar (incl plant-based options) * And most people stay until late for drinks and mingling! **DISCUSSION FORMAT:** **\- Our group conversations are open and flexible\! There is a very soft guided flow to ensure we focus on the key questions\, and to ensure that everyone gets a balanced opportunity to speak\.** \- We rotate groups intentionally during the discussion so everyone gets to meet a wider mix of people and perspectives\. \- After the structured part\, you’re free to mix and mingle with anyone\. **Here's a typical discussion structure, but we may adjust this depending on the turnout:** \- Introductions and initial thoughts *(\~5 mins).* \- Group breakouts per question *(\~20 mins x 3).* \- Final round of opinions *(\~10 mins)*. \- Mix and mingle\, make new friends\, get drinks etc *(\~until late)* **Rules & etiquette:** 1\. Debate the topic\, not the participants \- no personal attacks please\. 2\. No phones\, no interrupting\, no bystanding\. 3\. Always follow the moderator/host instructions and guidelines\. **WHAT IS WORLD CITIZENS?** We're one of London's longest-running and largest communities.

**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.

"Humanity's insatiable appetite to colonise reached far into the stars, but they learned the hard way that some stones should remain unturned. Whilst aggressively terraforming Spawn home worlds, humanity stirred the ancient species out of their slumber and incurred their rage in a cataclysmic event. Now conflict dances across the cosmos as the Spawn seek violent retribution by assimilating themselves among humanity and destroying them from within. Humanity’s only hope of survival is to detect the Spawn among them and destroy the threat." The Spawn is a large-scale elimination-based social deduction game where humanity must root out the Spawn which have infiltrated their ranks or be overpowered by them. Strategic gameplay, social subterfuge and gripping sci-fi all in one immersive experience.

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.**

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.

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.

We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant. *** Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'! Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists.

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

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)
