[Robin Linacre](https://www.linkedin.com/in/robinlinacre/) - **Rapid deduplication and fuzzy matching of large datasets using Splink** This talk introduces Splink, a free and open source Python library for probabilistic record linkage and deduplication at scale. I’ll explain the core ideas behind the approach, show how it can be used in practice, and reflect on the opportunities of building open source tools from within the public sector. Data deduplication is a common data quality challenge: it arises whenever multiple records are collected about the same person, organisation, or entity without a shared unique identifier. This talk will introduce the core ideas behind probabilistic record linkage and show how Splink, a free and open source Python library developed at the UK Ministry of Justice, can be used to link and deduplicate large datasets quickly and accurately. I’ll cover the practical steps involved in training linkage models, using unsupervised learning, improving performance and accuracy, and visualising results and diagnostics. I’ll also touch on what it has been like to build and maintain open source tooling from within the UK public sector, and the opportunities this creates for solving problems at citizen scale. The talk is aimed at people with basic experience working with tabular data in Python, and assumes no prior knowledge of record linkage. 2. [Filip Makraduli](https://www.linkedin.com/in/filipmakraduli/) - **Small Model Inference Infrastructure: Lessons Beyond vLLM** Embedding models are evolving rapidly, from dense-only architectures, to hybrid dense+sparse (BGE-M3), multi-vector late interaction (ColBERT), and vision-language models (ColQwen2, SigLIP). Yet while LLM serving infrastructure is well-established (vLLM, SGLang), small model deployment still relies on inefficient single-model containers or custom-built systems. Production teams face a dilemma: deploy dozens of single-model containers with 5-10% GPU utilization, or invest months building complex multi-model infrastructure. This talk explains some of the key concepts of embedding inference and how it is different to LLM inference. 3. [Ian Ozsvald](https://www.linkedin.com/in/ianozsvald/) - **Build your own LLM, Live, with MicroGPT** Andrej Karpathy's MicroGPT is a single file no dependency mini GPT, you can run it live with me. We'll talk about how GPT works, we'll look at the code, we'll reflect on the Torch-based nanoGPT "big brother" and you'll end the talk with stronger intuitions about how our next best token guessing overlords are working. Plus you'll have a mini GPT running on your laptop in 200 lines of Python. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **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.

Hello and welcome to our next **GenAI UK x Cloud Native & Open-Source AI** meetup. This event brings together engineers, practitioners, builders, and leaders working across cloud-native platforms, open-source ecosystems, Gen AI, Data and Agentic AI. Our meetups are friendly, welcoming, and community-driven; everyone is welcome, whether you’re experienced or just curious. This session will include practitioner talks, demos, Q&A, and time for networking with like-minded peers. We run bi-monthly in-person meetups in London, bi-monthly online global events, and regional chapters across the UK, North America, and APAC. Food and refreshments will be provided for in-person events where a host venue is supporting. We are delighted to host this event in **London** on the **7th of May** with Netmind AI NetMind XYZ ([https://xyz.netmind.ai/](https://xyz.netmind.ai/)) is NetMind.AI's new agent platform where you can create your agents with just natural language. Agents on NetMind XYZ can now join moltbook. **Speakers and Sessions:** Speaker: Xiangpeng Wan, Product Lead at Netmind.AI Session Title: Enterprise Agentic Application Layer - Leveraging Claude Code Paradigms Description: The March 2026 Claude Code leak exposed the blueprints of enterprise-grade AI agents, revealing advanced paradigms like Multi-Agent Swarms, Context Engineering, and IDE Bridges. While the codebase remains legally untouchable, its architectural concepts are rapidly accelerating open-source infrastructure. This presentation dissects these core mechanics to highlight a critical strategic pivot: stop reinventing frameworks and start building applications. As underlying agent infrastructures become commoditized, the true competitive advantage now lies in integrating domain knowledge and optimizing UX. Join us to learn how to leverage these battle-tested philosophies to dominate the application layer, turning "radioactive code" into actionable product strategies. Speaker: Richárd Kovács, CTO at Harikube Session Title: From Orchestration to Platform: The Missing Puzzles to Unify Polyglot Services on Kubernetes. Description: Imagine a world where Kubernetes itself becomes the unified platform—not just for container orchestration, but for serverless functions, microservices, and the entire API ecosystem. This presentation explores the missing architectural pieces required to make that world a reality. We focus on the architectural puzzles required to unify these layers: serverless functions, specialized Kubernetes Operators, and the powerful Aggregation API layer. By solving these integration puzzles, you can empower development teams to build real Cloud-Native nanoservices, microservices, and REST APIs on the same PaaS, in any language they choose, turning Kubernetes from a simple orchestrator into a powerful, opinionated application platform. **Agenda (GMT /UK ):** * 18:00: Welcome and refreshments * 18:30: Introduction - Ethan Sumner * 18:35: Richárd Kovács * 19:10: Break * 19:20: Frank Contrepois * 19:55: Close and Networking **Get Involved:** We are always keen to hear from: • Speakers — case studies, engineering deep dives, lessons learned, open-source talks • Hosts — organisations able to provide space for future meetups • Sponsors — support with refreshments, marketing, or accessibility If you would like to speak, sponsor, or host a future event, please get in touch with **[Ethan Sumner](https://www.linkedin.com/in/ethansumner404/)**[ ](https://www.linkedin.com/in/ethansumner404/)via LinkedIn.

Do you want to submit a talk to a Postgres conference? Do you want to try out the challenge of fitting a bunch of interesting information into 5 minutes for a lightning talk? Can you talk for 1 to 2 minutes on a Postgres topic you've just heard? On the 6th of May, we will be back at Star of Kings, running an event which is all about speakers and speaking. With the Call for Papers for PGDay UK closing on the 12th, we are inviting anyone who has a talk idea, is unsure of whether the topic fills the time, or just might enjoy a bit of technical improv to join us. If you would like to present a talk or a lightning talk, please get in touch. We will update this event description a people come forward. In the absence of any volunteers it will be Postgres-themed improv talks and, maybe, an organiser taking a talk for a spin. Don't let it come to that :)
