🌌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 and and not just ask the existential questions but 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. Join for the last chance to view the **Orion Nebula** where stars like our Sun were born - through telescope as the manned **Orion spacecraft** reaches its closest approach - a modern lunar rendezvous unfolding above us. 🚀 But there’s more. We’ll also see **Venus,** **Jupiter** along with planet's potential life‑harbouring **moons**, iconic **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 night sky — 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 .

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.

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.**

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.

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. 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. All attendees are welcome but should support our vision. Atheists of Columbus (AoC) is part of Omnipresent Atheists (OA).
