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.

Over the last nine years, Silverfit has been able to offer exercise to everyone over 50 in Brockwell Park. Together with Silverfit, I have done my best to keep the exercise fun for everyone, no matter if you are fit or not so fit, strong or not so strong, sporty or not so sporty. And, over all, I think we have done that pretty well! We have had some glorious years, and we made many, many friends over that time. Silverfit managed to keep it going through the good times and the hard Covid years, but unfortunately, the reality of the current economic climate is hitting Silverfit hard. Many councils and charities that have supported Silverfit over the years have stopped funding, and without funding, Silverfit just simply cannot keep going. Recently, they have had to take the hard decision to cut quite a number of their activities, and unfortunately, Nordic Walking in Brockwell park is one of the sessions that needs to be stopped. Yesterday afternoon was our last session for Silverfit. But…. I aim to keep your Tuesday walk going! So many of you love our Tuesday session, and it would just be too sad to stop completely. I would like to keep the Silver Tuesday session going under my own company, Fit and Happy Outdoors. Sadly, I cannot do this for free, as I do need to make a living. But in order to keep this session available for everyone, I plan to keep our Tuesday afternoon session at a highly reduced rate compared to my normal rates. New rates for our Silver Tuesday walks: 10 sessions for £45 (my normal rate is 10 sessions for £90). For those of you who struggle financially, I am happy to reduce this rate to £30, or even offer it for free. I can of course only do this if enough of you pay the normal rate, and I trust you will only ask for a reduction if you really need it. As I said, I do this for my living, but I don’t want money to be the reason you miss out on the benefits of Nordic Walking and spending time with our lovely group of friends. If you are already a member of Fit and Happy Outdoors and you pay monthly, then the Tuesday session is included in your fee. No extra payment is necessary (unless you’d like to sponsor someone who cannot pay) How does it work? 1) Please email me at Ailien at Fitandhappyoutdoors dot com, and let me know if you agree with me sending you an invoice for the full rate, or if you need a reduced rate. 2) I will then send you an invoice with my bank details on it. 3) Once I have received your payment in my bank account, I will hand you a 10-session card at the first session I see you 4) Every time you come walking on Tuesday, I will stamp your card 5) Once you have walked 10 times, I will send you a new invoice for the next 10. Payment: I really, really, prefer bank transfers. If you really do not do bank transfers, then you can pay me in cash. No cheques please (I really try to avoid having to go to the bank, it is just too much hassle). If you or a friend only comes once in a very blue moon, then they can pay £5 in cash for the session (only banknotes please. Help a girl out, I do enough weightlifting already 😊) Are you a walk leader? You are always welcome and do not have to pay me. I am grateful for your help! Do we still need to sign up? 1) Have your own poles? No need to sign up. But, if there is a weather warning, please check in with me as I might have to cancel and if I don’t know you are planning to come, I might not be able to tell you it’s cancelled 2) Happy to use the Meetup app, then sign up for your walk here? If you sign in, I will know you are planning to come, and it will be easy for me to let you know if I do need to cancel a session. 3) Need to borrow poles from me? Please text me ON THE DAY OF THE WALK to ask me to bring a set. My number is 078 078 3456 4. Just use normal text, no Whatsapp please, as I will probably miss your message. Any questions? Feel free to reply to this email, or text me on the number above.

The London Mountaineering Club's weekly club night at Westway takes place every Tuesday. There will be many more of us at the wall than listed on this event. To find us, look for people wearing an LMC T-shirt. This is a friendly meetup for competent climbers (at all levels of aspiration) to find people to climb with. If you have not climbed at Westway before, you will need to pass Westway's safety test before you can climb unsupervised. If you are unsure whether the centre will allow you to climb unsupervised please message the event organiser on Meetup in advance. We may be able to arrange supervision for you to climb without passing the test but this depends on club members being available to supervise and places will be limited. The London Mountaineering Club does not charge for this event but you will need to pay the entry fee to Westway and for any gear hired. Details of the Westway climbing wall are available on the [Everyone Active website](https://www.everyoneactive.com/centre/westway-sports-fitness-centre/climbing/) including [prices](https://www.everyoneactive.com/centre/westway-sports-fitness-centre/?activitySearch=casual%20climb).

Join OutdoorLads popular weekly Thursday Bouldering evening at The Arch in Bermondsey. OutdoorLads London boulderers welcome all members of the LGBTQ+ community You'll be meeting with a supportive group of 5 to 10 plus boulderers who are always happy to introduce complete beginners or solve difficult bouldering problems with enthusiasts. We usually follow up with a pub visit. This event is for members of all levels of experience and all are welcome to come along to any of the sessions. Bouldering is a form of climbing where instead of long high routes, the 'problems', as they are referred to, tend to be shorter and focus on technique, balance, body positioning and sometimes power. Because of this different emphasis, bouldering doesn't have the hassle of climbing with ropes, harnesses and belaying, which makes the activities excellent for newcomers to the sport. If you're a seasoned climber you won't need convincing about the benefits of bouldering, but for those who've never climbed more than a staircase, the benefits are wide ranging: from the physical - improved strength, tone, balance, power and coordination; mental - problem solving, focus, concentration and body awareness; to the emotional - relaxation, a sense of achievement and a feeling that mind and body are working together perfectly ('feeling psyched'). On top of all this, bouldering tends to be a very social sport where you can hang out with mates and each have a go as you feel regardless of what level you climb at.

CHERRY BLOSSOM, BLACKHEATH VILLAGE, PARKLAND, LAKE, followed by SOCIALISING with CHEAP FOOD and DRINKS in a convivial pub atmosphere. **WALK START POINT: LEWISHAM Station** (DLR and National Rail). Look for Ken with the Kens Events/Meetup Flag/Badge outside the station. The fastest way to get to Lewisham is to use British Rail from/via London Bridge (8 mins). WALK ROUTE: Blackheath to Greenwich Park (Cherry Blossom). WALK DISTANCE: Approx 4.5 miles. WALK END POINT: Cutty Sark Station. WALK STOP OUT POINT: We cross several London bus routes. BREATHE FRESH AIR: Give up the city streets for a day and improve your overall fitness levels on a green walk. Explore and enjoy London's abundant and sometimes secret green spaces, forest areas and surprising surrounding countryside. Meet new people and make some new friends. Walking is a great social activity. Visit parts of London, unknown to most people, that you would not otherwise have a reason to see. Afterwards there will be an option to head off to a local bar for something to eat/drink to continue the socialising. When you arrive at the starting point look for the Ken with the red and white Meetup Badge **Cost of Event £5 :** To allow for maximum flexibility for attendees, this event is free to RSVP.

**About** THE CASTLE CLIMBING CENTER has about 135 roped/auto-belays numbered routes with each route having up to 6 grades giving it approx 700 routes in total. THE CASTLE CLIMBING CENTER offers bouldering, top-roping, leading and auto-belays at their center. Some of us prefer bouldering while others will be in the top roping, leading or auto-belaying - this is up to you! We climb for a couple of hours and then the group regroups at 12.00 noon sometimes without me other times with me in The Brownswood pub, 271 Green Lanes, Finsbury Park, London N4 2EX for a spot of lunch and a libation. (https://goo.gl/maps/S4FZ9j1AYMPDs7uQ6) a stone's throw from the castle. **Meetups** We get together every Thursday & Sunday at THE CASTLE CLIMBING CENTER meeting at 9:00am in the warming up area or else look out for someone wearing a black RAMS t-shirt around the center. If you're joining for the first time let us know via message and we will keep an eye out for you at the start :) **New Climbers!** Unfortunately, if you haven't climbed before it isn't as easy as just turning up and climbing up the wall. To climb safely you need to understand the hazards and be able to use the equipment correctly. You must have basic climbing skills and know how to put on a harness, attach a rope to a harness using a rethreaded figure of eight(figure of eight on the bight) and know how to use a belay device to pay out the rope and secure a falling climber etc. So before your first climb, you may be required by the climbing center to fill out health and safety forms. This may involve a quick test on climbing rules at the counter on arrival. Please add an extra 10/15 minutes before your session if you need to register for the first time. THE CASTLE CLIMBING CENTER terms and conditions will apply. Please also note signing up for the Meetup session won’t necessarily grant you access to the center. **Other communication** Within these groups, you are possibly likely to develop long-lasting friendships. Don't forget we have a Discord page and WhatsApp https://chat.whatsapp.com/JNJ81oLSKB2JGaNm79em0C. The group will always be very varied when it comes to climbing levels, abilities and modality preferences. Do shout out if you have any questions. If you want to have a chat about this or other meetups, or just to keep in touch, ask to join us on Discord and/or WhatsApp. We have a dedicated THE CASTLE CLIMBING CENTER chat, but also talk about all things climbing (and some non-climbing!) including trips, gear talks and looking for climbing partner/s situations. **You’ll Rock it** A word of warning this sport is very, very addictive once bitten your its mistress for life. The simple challenge of you against the rock is sublime, there are competitions but then really the only real competition is 'you and the rock'. As climbing can be a very social activity we look forward to sharing our passion with yours. *Happy climbing!* p.s. Eventually, we will be starting and incorporating our climbing academy where we aim to bring skills, ropework and technique etc to enhance your climbing ability, using 25mm chalk bag colored belts to indicate your level. Naturally, THE CASTLE CLIMBING CENTER will also run courses to help improve your techniques too. Contact THE CASTLE CLIMBING CENTER for more info.

Feel free to ask any questions in the comments section! IMPORTANT Please bear in mind this is a free of charge, self-guided trip with a hobby group. It is not organized by a business nor any entity with commercial purposes. Any trip details, travel advice, route planning, instructions and other content in our group merely represent our shared personal knowledge, research and suggestions as outdoor enthusiasts. As this is no business, there is no "product", "service" or "package" and also no "tour guide", "operator" or "walk leader". Each participant is responsible for their own safety. Even if some of us are very experienced walking outdoors, nobody assumes responsibility for any kind of injury, damage or loss that may happen. Despite this, we take extreme precautions and all trips we plan are very safe, fun, highly educational and popular. Our experienced members volunteer their time and effort to shape a pleasant and quality adventure for everyone :-) By participating you acknowledge and agree with this disclaimer. Here are our tips on staying safe during outdoor trips: http://www.meetup.com/Free-Outdoor-Trips-From-London/about/ TRAVEL, ACCOMMODATION, INSURANCE Although we provide detailed suggestions, each participant is expected to arrange their own travel - this gives everyone the freedom and choice. Anyone interested in travel or outdoor insurance should also arrange this on their own. As mentioned above we always take extreme precautions, but some people may still feel safer if covered. As most of our trips are confirmed or postponed very close to the event date - heavily depending on the weather forecasts - we advise not to buy this until the last minute. People getting tickets from the same station are encouraged to meet early on the day to benefit from discounts such as GroupSave.

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.

Meet at Wolfe Park parking lot by tennis courts. We willl walk along Alum Creek trail, through Jeffrey Mansion Park then along Bexley neighborhood and back. Optional lunch at Trolley District.

We meet at lunch each week and each meeting follows a fairly organized agenda. First all participants pass their business cards around. Then each member and guest is invited to give a one-minute overview of their company and what is a perfect referral for the week. We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot. Bring plenty of cards!

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

Join us for a two mile trail hike alongside the Brookside Trail at Blendon Woods Metro Park. This trail is largely gravel and does include some hills and stairs. Hopefully we will see some wildlife while hike this scenic trail! Join us!
