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).

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.

**EVENT OVERVIEW** Join us for an intimate Kundalini Activation session designed to awaken your life-force energy and reconnect you with your authentic self. Limited to just 6 participants, this 2-hour experience offers profound emotional release and spiritual transformation through gentle surrender - no yoga poses or breath-work required. **WHAT TO EXPECT - SESSION AGENDA** **12:00-12:15pm - Welcome & Introduction** * Meet fellow participants in our intimate group setting * Brief overview of the Kundalini Activation process **12:15-12:30pm - Body Scan Meditation** * Guided meditation to help you reconnect with your body * Entering a surrendered, receptive state **12:30-1:30pm - The Energy Activation Process** * Carefully curated music journey * Energy Transmissions and individual attention * Safe space for whatever wants to emerge naturally **1:30-2:00pm - Integration & Sharing Circle** * Tea and chocolate provided * Optional sharing of experiences * Connect with your new spiritual community **WHAT IS KUNDALINI ACTIVATION?** Unlike Kundalini Yoga that relies on physical postures and breath-work, this journey is one of complete surrender. The intelligent life-force energy naturally rises within you, awakening dormant parts of your being and fostering growth on emotional, mental and spiritual levels. This intuitively guided process works in harmony with your unique needs, gently releasing stored emotions and helping you rediscover your authentic self. **THIS IS PERFECT FOR YOU, IF YOU:** ★Want to find your authentic self through awakening your Kundalini ★Have tried therapy or other modalities but feel they haven't touched the deepest parts of what you need to release ★Are seeking the truth within - who you are at the level of identity OR beyond the identity ★Value intimate, personal, exclusive spaces (max 6 people) over large groups ★Are ready for deep transformation, not just relaxation ★Want tough motherly love from Kali energy that will destroy everything that isn't true for you **WHY SMALL GROUPS MATTER** This journey touches the deepest parts of who you are. In our intimate 6-person setting, you can surrender fully to whatever wants to emerge - whether it's tears you've held back for years, anger you've suppressed, or joy you've forgotten how to feel. The smaller group creates a safer space for emotional vulnerability and deeper connections that larger groups simply can't offer. **LOCATION & PRACTICAL DETAILS** Mind Body Soul Hub, Unit A, 222 South Street, Romford RM1 2AD (5-minute walk from Romford Station, Elizabeth Line) **INVESTMENT:** £55 per person **WHAT'S PROVIDED:** Yoga mats, blankets, and all equipment **WHAT TO BRING:** Just yourself and an open heart **SESSION TIMES:** Every Saturday 12-2pm and some Friday evenings 8-10pm **WEBSITE:** https://www.kundaliniuntamed.com/romford-sessions **HOW TO SECURE YOUR SPOT** **Do I need to purchase a ticket?** Yes!

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.**

### 📅 EVENT DETAILS 📍 **Where:** Aldgate Tower (just outside Aldgate East Station, Exit 1) 🙋 **Who:** Players who already know how to play with scores (not suitable for beginners) ☕ **Included:** Instructor help, free tea, coffee, and unbeatable vibes ## 🀄 WANT TO PLAY MAHJONG REGULARLY? Mahjong is still a niche board game in London — and since it needs **4 players**, it can be hard to organise regular games with just your own friends or family. In many parts of Asia, **Mahjong parlours** bring people together to play. While we’re **not** running a commercial Mahjong club, we *are* here to build a **community**. Many of our players started as complete beginners in our workshops — and now they’re **hooked**! That’s why we created our **🎟️ Just Play tickets**. ### 🌏 DIFFERENT MAHJONG STYLES WELCOME ### 🇭🇰 Hong Kong Style (Main Style) Our main style is **Hong Kong Mahjong**, with a **3 fan minimum to win**.If you know how to play other Chinese styles like **Taiwanese**, **Sichuan**, or **British Mahjong**, you’re still welcome! We’ll provide **scoring cards** to help you adapt. ⚠️ However, these tables are **not suitable for beginners**. If you haven’t yet graduated from Level 1 or Level 2 of our workshops, or if you don’t know how to score, please join our learner workshops first to build confidence. ### 🇯🇵 Japanese Riichi (Growing Community) Riichi Mahjong is **new to our community**, but we love its fast pace and strategic complexity!If you already know how to play Riichi — \*\*amazing! Please join us.\*\*If you play Chinese Mahjong and want to try Riichi, one of our instructors or friendly regulars might help, but we **can’t guarantee full teaching support yet**. You're welcome to learn by playing alongside others. ### 🇺🇸 American Mahjong (New Community in 2026) We’re excited to add **American Mahjong** to our offerings. It’s quite different from Chinese Mahjong, so we’ll run newbie workshops and regular Just Play sessions from 2026. **Note**: Just Play bookings require solid prior knowledge of American rules. However, we encourage cross‑style learning, so if you already know one style of Mahjong, learn another with us, so you can play at any table. ## 💷 OUR BEST PRICE PROMISE We’re doing our best to keep **Just Play tickets affordable** for a 2-hour session — that’s our **best price promise**. 🙌 Unlike clubs that charge entry or venues that require a minimum spend, our ticket price covers only what’s needed: venue, staff, admin cost. And yes — with a booked ticket, **YOU ARE GUARNATEED A SEAT AT THE TABLE**, and we also provide **free tea, coffee**, and the occasional **festive treat**. ☕🍪 We're not a charity, but we are **deeply committed** to creating a welcoming Mahjong community. 💛 Your support helps us keep the tiles clicking, and we love seeing familiar faces return week after week! ## 📱 JOIN OUR MAHJONG WHATSAPP COMMUNITY Stay connected with fellow players in our friendly WhatsApp group — a space to ask questions, get updates on upcoming events, and even arrange private games outside of our Saturday sessions. It's the easiest way to stay in the loop and grow your Mahjong circle! [LINK HERE](https://chat.whatsapp.com/IQXv3nGfbeMCfvI6HsGjfZ "https://chat.whatsapp.com/IQXv3nGfbeMCfvI6HsGjfZ") **Important Notes** 1. Each attendee must be registered to our building in addition to the meetup ticketing. If you book two tickets, we will need both individuals’ full names and email addresses for registration. 2. On **the same week**, you will receive an email from "Aldgate Tower" with your **building entry invitation**.

Please check your **spam or junk folder** if you don’t see the email. Still nothing? Send us a message / whatsapp us on +44 7423 755734 , and we’ll assist you promptly.

**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.

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.

Ciao a tutt\*! Let's meet Monday at 6.30pm at the Upper Arlington Library (**Tremont** Branch) in **Meeting Room A** to speak in Italian for 1 hour.

**Our April novel is: *The Hong Kong Widow* by Kristen Loesch** **This month’s novel blends gothic atmosphere with historical fiction and chilling horror, set against the haunting backdrop of China. The book is 368 pages in print and 10 hours and 42 minutes on audiobook.** In 1950s Hong Kong, Mei is a young refugee of the Chinese Communist revolution struggling to put her past in Shanghai behind her. When she receives a shocking invitation—to take part in a competition in one of the city's most notorious haunted houses, pitting six spirit mediums against one another in a series of six séances over six nights, until a single winner emerges—she has every reason to refuse. Except that the hostess, a former Shanghainese silent film star, is none other than the wife of the man who once destroyed Mei’s entire life. It is promised the winner will receive a fortune, but there is only one prize Mei wants: revenge. Decades later, the final night of that competition has become an infamous urban legend: The police were called to the scene of a brutal massacre but found no evidence, dismissing it as a collective hallucination. Mei knows what she saw, but now someone else is convinced they know what she did. She must uncover the truth about the last night she ever spent in that house—even if the ghosts of her past are waiting for her there. . . .
