🌌Ever look up and marvel with insatiable curiosity at the beauty and wonder of the **universe?** That wild sobering thought that somewhere in the chaos of creation - the emergence of life - the universe became **conscious** enough to look back in time and not just ask the existential questions, but try to answer them. And now, in our own small moment of cosmic history, as we return to the Moon aboard the most powerful rocket ever built, the **Artemis mission** carries that ancient curiosity forward. As the manned **Orion spacecraft** -currently just 18k miles from the moon - reaches its closest approach, join for the last chance to view the **Orion Nebula** through a telescope as the historic lunar rendezvous unfolds above us. 🚀 **But there’s more celestial wonder**: As those four astronauts venture deepest into space than any humans have ever been before - we’ll tale a look at **Venus,** **Jupiter** along with planet's potential life‑harbouring **moons**, iconic beautiful **star fields**, the remnants of supernovae witnessed by our earliest ancestors, **multi‑star systems** reminiscent of the twin suns of *Star Wars* and even **Tau Ceti**, a star hosting two Earth‑like worlds in its habitable zone. All of this under the spring evening - with drinks, engaging conversation, and good‑natured banter — this April. In between observing - we'll have **drinks and engaging chats** on all astronomy related topics for those inclined: Space exploration \| Fermi Paradox \| Astrobiology \| Cosmology \| paleontology\, \| SETI & Drake Equation for alien civilisations estimates \| exoplanetology etc as well as non space chats and banter too\. No doubt we'll hear the usual jokes we've all heard before\! If those don't make you laugh\, my impersonation of Los Angeles ET will\! 👽 And to help set the mood and make the night feel even extra galactic, I’ll put my DJ hat to play some space‑themed tunes and songs about the stars! You don't need a telescope as you will be able to view through scopes belonging to me and other club members (as long as you behave responsibly and don't temper with expensive equipment). If you have your own telescope/binoculars feel free to bring along and I can help you setting it up if you're a newbie **==== ITINERARY =====** We will meet outside H&I Station in Highbury Islington. After a short wait for anyone delayed, I will escort everyone to our observation point in the local park 5 minutes walk away and brief you in terms of what to expect, observing etiquette, tips, equipment handling and take any questions you have - weather general or astronomy/cosmology related. **After Drinks:** Unless I have a very important 9AM Tue deadline for a unfinished client presentation or something - most of us usually head to a cosy bar for a drink. If so - I will annouce the pub when we leave the park **==== What Can You Expect To See (this time of year)? ====** * Orion Nebula * Jupiter and 4 moons * Meteors * Andromedia Galaxy * Star clusters such as the Pleiades & Owl Cluster etc * International Space station fly by * Binary & tripple star systems (think planet *Tatooine in* Starwars!), * Neptune * Uranuus * Our moon * A look towards the galactic centre of the Mlikyway where that supermassive £22b Labour black hole sits (Sagittarius A) More here from Jodrell Bank Observatory/Astrophysics Centre: [http://www.jb.man.ac.uk/astronomy/nightsky/](http://www.jb.man.ac.uk/astronomy/nightsky/) Guide to viewing the cosmos for beginners: [https://phys.org/news/2018-05-universe-distant-starstips-cosmology-backyard.html#jCp](https://phys.org/news/2018-05-universe-distant-starstips-cosmology-backyard.html#jCp) **===Weather Dependent=====** The event is subject to clear skies forecasts on the night so if on the actual afternoon of the event the weather forecasts looks unsuitable beyond doubt then I will postpone so please check the event status on the day of the event . If this event is still listed here at 5PM on the day, it will be going ahead at the designated day and time! Lucas Skywalker - The Singin, Dancin, DJ-in Astronomer

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.

This event follows the [NumFOCUS Code of Conduct](https://numfocus.org/code-of-conduct). Please familiarise yourself with it before attending. If your RSVP status says "You're going" you will be able to get in. No need to show your RSVP confirmation when signing in. If you can no longer make it, please unRSVP as soon as possible. **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. **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.

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.**

**Important:** Register on the [event website](https://www.aicamp.ai/event/eventdetails/W2026040809) is required for admission. **RSVP on meetup is turned off** Enjoy afterwork drinks and practical discussions on Apache Kafka, ClickHouse, PostgreSQL and much more. Enjoy a session designed for data engineers, architects and technical decisions-makers like you, who want to address the challenges they face in data-infrastructure.

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)
