Praed Street Picture Hunt
St Mary’s Hospital was founded in 1845 on Praed Street as a voluntary hospital for ’the deserving sick poor’ and opened the Medical School in 1854. Alexander Fleming discovered penicillin there.
This is another of our many outside Picture Hunts this year. If any issues with weather, we’ll switch to our 50-50 Trivia in the nearby Wetherspoon Sir Alexander Fleming, so turn up as something will be on regardless.
If you’re new to Picture Hunts, check previous events for winners and clue sheets.
This time, the event will be centred around different shops on one side of Praed St, Paddington, so there’s no crossing of busy roads.
Please aim to turn up for 1:00-1:30 when teams are being arranged. The Hunt starts at 1:30. You're losing search time if you're late! Bring a pen please.
As usual, portions of the road are split up into four areas where teams search for the locations of photographed items in the street, buildings or shop windows, and then record where they found them.
Picture Hunts are a great new way to get up to speed with slices of London history while sleuthing around the area.
Everyone is presented with twenty partial photos of objects around an area. Your team mission is to find them. Some well known, some well unknown!
This makes Picture Hunts more interesting and challenging, bringing out the best of your teams detecting skills.
You will also have a map of the area. It will be sub-divided into four sections, P, Q, R, S. Each photo will come from one of these.
Four players max per team, but the lower number teams get a point per player start from the biggest team.
For example, four teams of one, two, three and four. Four player team, no advantage, (the biggest and theoretically the more knowledge between them, except it doesn't always work like that). Three player team, one point start. Two player team, two point start. One player team, three point start.
Scores are always close and around the 15-20 points mark. How many players do you want in your team? There's a dilemma!
The clipboard holder enters one of the letters to note its area location. Dead simple, right? 90 minutes to do the hunt.
We have the usual prizes of chocolate, including some great new varieties.
There is also an equal prize for the funniest team name judged by Sue, my glamorous assistant. Names win prizes too! So there’s everything to play for.
We mark up at the quiz finish point. The Wetherspoon Sir Alexander Fleming.
Hunts are good fun and the proven experience so far is that members get to know each other better after working in teams as you all have to communicate. Great icebreakers.
This is what Meetup is all about. Come and join us.
There is a £7 cash/card charge for this event.
Contact number on the day is 07422334411 if your transport is delayed.

London Bridge Writers' Group - Pub Meet
**The Talbot Room at the George Inn**
The George provides the room free of charge (they are awesome), and we encourage you to purchase drinks (and food – the burgers are great!). As it’s a pub and not a picnic area, please don’t consume your own food and drink there.
We usually meet in the Talbot room which is on the top floor on the left hand side of the pub as viewed from the courtyard. If lost please send a message here shortly before the meeting starts.
**We are sorry to say that there is no step-free access to the Talbot room, and it is at the end of three flights of stairs.**
**Format**
We start at 7pm and run until 9pm. We hear approximately six readings of 10 minutes (\~2000 words), then discuss the piece for 10 minutes. Email your work to: london60transmitter@emailitin.com as an attachment (It must be an attachment). A link for access to googledocs will be given at the start of each session to enable people to read along, which in turn enables more considered feedback. Work submitted will be automatically deleted after 10 days. We decide on readers/pieces at the beginning of each session.
**Safe and respectful space**
The group is run by volunteers, and we don’t have the capacity to read submitted work in advance. If there is anything in your work that might distress or disturb some readers, for example concerning any kind of abuse, please give a trigger warning before you read. Be specific and concise. If it becomes apparent during a reading that a piece is inappropriate, the moderator will stop the reading. In discussing others’ work, please be mindful of how you express yourself and do not use discriminatory language, even if such language features in the piece.

1\. 🚨🚨🚨 A valid photo ID is required by building security\. 🚨🚨🚨
2\. This event follows the [NumFOCUS Code of Conduct](https://numfocus.org/code-of-conduct). Please familiarise yourself with it before attending.

**Code of Conduct:**
This event follows the NumFOCUS Code of Conduct. Please get in touch with the organisers with any questions or concerns.
As always, there will be free food and drinks, generously provided by our host, Man Group.
**Main Talks**
1. **[Nicoleta Lazar](https://www.linkedin.com/in/nicoleta-lazar-921a6864/) Query federation in modern OLAP databases**
As analytics ecosystems grow more diverse, organisations increasingly need to query data across warehouses, data lakes, and operational systems without excessive data movement or duplication. **Query federation** has become essential by enabling unified SQL access and intelligent predicate pushdown into heterogeneous sources. 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.

April 2026 Meetup
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

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.
