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.

ATTEND IN PERSON OR ON ZOOM **NB** This event takes place on Tuesday as Monday is a public holiday in the UK Enlightened Self-Interest - The Moral Philosophy of Adam Smith On April 7, meet at Kant's Cave to listen to Sean O'Connor talking about the moral philosophy of Adam Smith. Smith is often portrayed as the philosopher of selfishness and free markets. But was he really? In fact, Smith was first and foremost a moral philosopher, deeply interested in sympathy, human motivation, and how people cooperate in society. Drawing on close observation of human behaviour, his work offers a far richer view of self-interest than the stereotype suggests. In this talk, Sean O’Connor will introduce Smith’s ideas and explores what they reveal about morality, self-interest, and human cooperation today. Event video teaser: https://www.youtube.com/shorts/Mfx-yPp-bD0 Sean O’Connor spent over twenty years as an advertising executive before becoming a serial entrepreneur, assembler of private equity projects, investor and corporate strategist. He has been the Chairman of a number of public and private companies and a director of many others. His acclaimed novel, *The Prisoner’s Dilemma,* was published in 2013 and his four-volume series, *The Secrets of Life: From Big Bang to Trump* appeared throughout 2023. Every first Monday of the month (or Tuesday if Monday falls on a bank holiday in the UK), Philosophy For All invites its members and guests to attend Kant's Cave for a lecture, debate and social evening. This is a free event which takes place at 19:30 in the upstairs bar at the Two Chairmen, 39 Dartmouth Street, SW1H 9BP, London, but could also be joined online via Zoom. Kant's Cave events are supported by The Royal Institute of Philosophy's Local Partners Programme.

Rushmore is a 1998 American comedy film directed by Wes Anderson about a teenager named Max Fischer (Jason Schwartzman in his film debut), his friendship with rich industrialist Herman Blume (Bill Murray), and their shared affection for elementary school teacher Rosemary Cross (Olivia Williams). The film was co-written by Anderson and Owen Wilson. The film was selected for preservation in the United States National Film Registry by the Library of Congress in 2016, deemed "culturally, historically, or aesthetically significant". Please note we will not be showing the film at the meeting. Make sure you watch the film before you attend and then come and join in with the conversation. It’s just a discussion.

Your survival depends on knowing who you can rely on. But how can you tell who your real friends are? How can you determine if a person will help make a joint venture successful? Is there a way to predict behavior? Yes. There are fundamental elements to human behavior. When you know them you have insight into your fellow man, and just by observing how people act, you will know *everything* about them. #### On this lecture you will learn: * The important role of trust in human relationships. * The Hubbard Chart of Human Evaluation—the tool to know true character and predict what people will do. * How to evaluate others accurately and guarantee a more certain future for yourself and those you care about. With the knowledge you learn on this course, you will have tools to know who you can trust and who you can depend on. *“Trustworthiness is a highly esteemed commodity. When one has it, one is considered valuable. When one has lost it, one may be considered worthless.”* *—L. Ron Hubbard*

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

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.
