[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).

**Bookable via our website ➡️** [https://www.thegoodlifecentre.co.uk/events/upholstery-bring-your-own-chair-monday-eve-19/](https://www.thegoodlifecentre.co.uk/events/upholstery-bring-your-own-chair-monday-eve-19/) **⋆⋆⋆** KEY PROJECT: RE-UPHOLSTERING YOUR OWN CHAIR. Suitable for beginners and fun for advanced learners. This workshop is led by Krasmira Nikolova, an experienced upholsterer. We provide the use of all upholstery tools and equipment including compressed air staple guns. Basic upholstery materials that you require for your project will be moderately charged on a pay-as-you-use basis and will be dependent on each chair’s requirements. We can advise you on the purchase of your top fabric and we have a lovely library of fabric samples to help make up your mind. The Goodlife Centre sells all the basic tools and materials for use on projects worked on at home. This is a fantastic chance to up-cycle and personalise a family piece you have at home or a junk shop find and a great way to immerse yourself into the wonderful world of upholstery. The course is suitable for both beginners and those who have a basic knowledge but little experience who wish to extend their expertise. **Choosing a suitable chair** If you are a newcomer to upholstery, there are a couple of pointers to help you choose a chair to work on. Choose something that has one or two flat planes – a seat and a back – as curves and arms are more complex and take longer to achieve. The chair on the right was completed in about 12 weeks. If you are a complete beginner, you could bring something more simple such as an upholstered footstool. More experienced upholsters can bring more complex pieces. Your chair can be traditionally built or modern, but be aware that some modern pieces have been constructed using machinery and are difficult to recreate by hand. [Click here for a detailed PDF of suitable chairs.](https://drive.google.com/file/d/0B2r8UvbQtaH5RTVKUjlBdkhDX3c/view?usp=sharing) **Please email info@thegoodlifecentre.co.uk with a photo of your chair prior to the course so we can answer any suitability questions and advise if your chair is suitable**. We have very limited storage at the centre, so we can only store smaller pieces during the course. Please make sure the total dimensions are less than 1000mm high by 750mm wide, with a depth of 750mm. The use of tools and machinery is included. All materials will be charged at nominal rates. Some materials will not be kept in stock but can be ordered. Approved projects can be stored at the centre. We cannot offer additional time to work on your project outside of workshop times.

We are back from hibernation and would like to say a very warm welcome to *We Need to Talk*, the event series that discusses the most topical themes facing people in tech right now. Join us at the **Accurx Office** on May 5th for an evening of lively discussions, thought-provoking chat, and the opportunity to network with other curious and ambitious colleagues in tech. First, as ever, a huge thank you to all those who joined our last events, you keep us inspired to find the best topics and speakers. ***We Need to Talk*** is centred around creating a community to uplift each other, have open discussions and create an inclusive space for us all. We are so proud of this community - thank you for supporting us on this journey. Please invite your friends too and spread the word. For the upcoming event, our generous hosts **Accurx** will be kicking off the evening with a quick intro to who they are and what their mission is. This will be followed by our fabulous keynote speaker **Dr Lisa Plotkin** (Head of Policy and Influence at the Florence Nightingale Foundation) who needs to talk about ***When Hierarchy Fails: Lessons from 55 years of NHS scandals*** One year in, we also want to hear from you - what can you share on the good, the bad and the curious of using AI tools. We are hosting an **Open Discussion on AI Learnings** from Ethics to Hallucinations we would love to get your thoughts! Our favourite part of WNTT is how much intellectual debate takes place and we would like to learn even more from you. **Event schedule:** 6:00:🥤 Doors open 6.30: 🗣️ **Welcome and introduction from Accurx** 6.40: 🗣️ **DR Lisa Plotkin: *When Hierarchy Fails: Lessons from 55 years of NHS scandals*** 7.00: 💡 Q&A 7:10: 🍻 Drinks and networking 7:30: 🗣️ **Open discussion: AI learnings** 8.00: 🍻 (Optional): We offer a warm invitation to join us at the pub for a post event social and pizza - to carry on the talks. **Lisa's talk: *When Hierarchy Fails: Lessons from 55 years of NHS scandals*** **Power tends to protect itself**, and that is often most visible in the institutions we rely on most. Dr Lisa Plotkin works in nursing and midwifery policy and advocacy, within a workforce that is largely female, often undervalued, and frequently operating at the sharp end of both hierarchy and human impact. Drawing on a series of NHS inquiries, including Mid Staffordshire, Morecambe Bay and East Kent, she will explore how serious failures are not just isolated events, but emerge from deeper, systemic conditions. These include cultures that prioritise compliance over openness, sideline those who speak up, and leave those closest to problems without the authority to act. This talk will look at what these inquiries, taken together, reveal about how power really works in large organisations, and why the same lessons keep resurfacing. It will also consider what better looks like in practice, and what it takes to build cultures where hierarchy supports the work rather than shielding itself. Ultimately, the question is not simply who failed, but what needs to change so that failure is no longer the default. **P.S...** We would love to keep our events free and inclusive. We are orchestrating these events in our spare time and our hosts are generously gifting us the spaces to hold them. If you have signed up and can't make it any longer - we would really appreciate it if you let us know on Meet Up, it just helps us plan accordingly for the night. **P.P.S...** Please let us know if you have accessibility requirements, the venue has stairs internally and we want to make sure we can accommodate everyone.

**Bookable via our website ➡️** [https://www.thegoodlifecentre.co.uk/events/woodwork-step-up-low-wood-stool-6-evenings-4/](https://www.thegoodlifecentre.co.uk/events/woodwork-step-up-low-wood-stool-6-evenings-4/) ⋆⋆⋆ This lovely six-week evening course is another charming project from our cherished Edwardian instructional woodwork manual, ‘Carpentry for Beginners’. The projects in the book are perfect for learning basic woodwork skills and we have refined the instructions to incorporate a modern craft construction. This classic ‘child’s stool’ is a handy ‘hop up’ you can use if you have shelves you can’t reach at home and small ones can reach the sink by standing on it. It measures 40cm x 22cm x 26cm high. We use a redwood pine wood that releases a heady and uplifting scent when cut, chiseled, and planed. Even if you have never used any tools, our expert makers will teach you the processes you will need to take home a future heirloom along with a very special sense of satisfaction that comes with crafting by hand. Over six evenings you will learn how to measure and mark timber accurately, use a chisel and a vintage ‘Granny’s tooth’ hand router to cut out grooves to house the legs into the sides of the stool. By the time you have finished your useful step-up stool, you will have become familiar with many of the basic woodworking hand tools and increased your confidence to go on and do more general woodwork at home. All use of tools and materials included.

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 :)

**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 📓 **HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 13:45-14:00 - People arrive and chat, get to know each other before the ‘official' start. * 14:00-14:05 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 14:05-14:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 14:45 - We do a group conclusion of the things we discussed, and then we typically take a photo and go on our way :) If you don't want to be in the group photo, there's no pressure, it's just a way to close out the meeting. We occasionally have an unofficial social so the different groups can mingle afterwards too! **🧧PRICING?** Practical Philosophy Club is FREE to attend, and we operate on donations. If you'd like to donate to support our running costs, that helps keep our group self-sustaining. Donations are 100% voluntary, but your contribution is appreciated! QR codes to donate will be present. Tea’s and coffees and are paid by the individual should they wish to have them. **💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * What will we talk about? What's the topic? The topic for the week is shared every week in the Whatsapp group before the session. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/B6fqS6HGujq8gb3a0kl5pS) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/). 🤝**POLICY** To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group.

Join us on May 7th from **6:00pm** for a Data Streaming meetup hosted by **[Fresha](https://www.fresha.com/)**! 📍**Venue:** **Fresha** The Tower, 207 Old Street London, EC1V 9NR 7th Floor **PLEASE bring your PHOTO ID and REGISTER with your First and Last Name, Email. Thanks!** **DOORS CLOSE AT 7PM FOR SECURITY.** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:00pm: Anton Borisov, Principal Data Engineer, Fresha & Nicoleta Lazar, Sr. Data Engineer, Fresha * 7:00pm - 7:30pm: Olena Kutsenko, Staff Developer Advocate, Confluent * 7:30pm - 8:00pm: Tom Scott, Founder & CEO, Streambased * 8:00pm - 9:00pm: Q&A Networking 💡**Speaker One:** Anton Borisov, Principal Data Engineer, Fresha & Nicoleta Lazar, Sr. Data Engineer, Fresha **Title of Talk:** Apache Fluss: Streaming Storage for Real-Time Analytics **Abstract:** Apache Flink has largely solved streaming computation, but state management remains a bottleneck. Operator state—often backed by RocksDB—is scoped to individual jobs, making it hard to share state across pipelines without re-emitting it through systems like Apache Kafka. This leads to expensive joins and added operational complexity. Apache Fluss (incubating) addresses this by externalizing state into a streaming storage layer backed by S3. Its PrimaryKey tables act as upsertable key-value stores with replicated changelogs, enabling shared state tables accessible from Flink, Spark, or native clients. With Flink 2.1’s Delta Join, both sides of a join can perform lookups against Fluss-managed indexes—eliminating the need for large join state altogether. In this talk, we’ll introduce Fluss, show key use cases like CDC enrichment and bilateral joins, and share lessons from running it in production on EKS —including the trade-offs and rough edges we encountered. 💡**Speaker Two:** Olena Kutsenko, Staff Developer Advocate, Confluent **Title of Talk:** The journey of a record from Kafka topic to analytics table **Abstract:** Modern data platforms increasingly rely on streaming systems like Apache Kafka as the source of truth—but turning event streams into reliable, queryable analytics tables is far from trivial. This talk explores what really has to happen when moving data from a Kafka topic into an Apache Iceberg table. Beyond simple ingestion, we will walk through the essential steps: schema evolution, data normalization, partitioning, exactly-once guarantees, late-arriving events, and table maintenance. Using Confluent Tableflow as one concrete example, we will examine how these challenges can be addressed in practice. Along the way, we will compare alternative approaches—such as Kafka Connect sinks, stream processing pipelines, and custom ingestion frameworks—to highlight trade-offs in correctness, latency, and operational complexity. The goal is not to promote a single solution, but to provide a mental model for designing robust streaming-to-lakehouse pipelines, helping you understand what matters regardless of the tooling you choose. **Bio:** Olena is a Staff Developer Advocate at Confluent and a recognized expert in data streaming and analytics. With two decades of experience in software engineering, she has built mission-critical applications, led high-performing teams, and driven large-scale technology adoption at industry leaders like Nokia, HERE Technologies, AWS, and Aiven. A passionate advocate for real-time data processing and AI-driven applications, Olena empowers developers and organizations to use the power of streaming data. She is an AWS Community Builder, a dedicated mentor, and a volunteer instructor at a nonprofit tech school, helping to shape the next generation of engineers. As an international speaker and thought leader, Olena regularly presents at top global conferences, sharing deep technical insights and hands-on expertise. Whether through her talks, workshops, or content, she is committed to making complex technologies accessible and inspiring innovation in the developer community. 💡**Speaker Three:** Tom Scott, Founder & CEO, Streambased **Title of Talk:** *Infinite Kafka? Rethinking Retention with Iceberg* **Abstract:** Apache Kafka is designed for high-throughput, low-latency event streaming, not cost-efficient long-term storage. Yet we constantly see cases like event sourcing, audit/compliance, and large-scale reprocessing forcing that pattern onto it. As retention increases, costs grow linearly to support edge cases, one-time runs, and “checkbox” use cases. Can Iceberg help here? In this talk, Tom explores a hybrid architecture that separates hot and cold data while preserving Kafka’s log semantics. Using a combination of Kafka and Apache Iceberg, he demonstrates how to extend Kafka into low-cost object storage, enabling effectively unlimited retention without sacrificing performance or access patterns. The result is a unified log that supports both real-time processing and long-term replay, removing the traditional trade-off between cost and capability in Kafka-based systems. **Bio:** Long-time enthusiast of Kafka and all things data integration, Tom has more than 15 years of experience in innovative and efficient ways to store, query, and move data. Tom is currently CEO at Streambased, a company focused on unifying operational and analytical data estates into a single, consistent, and efficient data layer. \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

We'll likely go somewhere for food afterwards. See you then Xie

Join us on Wednesday 6th May for our next AI Exchange event, hosted by AWS at their Holborn HQ. Here's what's on the agenda: **[Nova Intelligence](https://www.novaintelligence.com/)** are tackling a problem that doesn't get talked about enough, most AI agents simply weren't built to work with enterprise software like SAP. Their talk discusses how they have solved that, and what it looks like when AI works as well in the enterprise world as it does everywhere else. **[WeBuild-AI](https://www.webuild-ai.com/)** are making the case that bigger isn't always better. Their talk breaks down how small language models, through distillation, fine tuning and low rank adaptation, can deliver the same results as larger models, at a fraction of the cost. **[AWS](https://aws.amazon.com/)** are tackling the question underneath all the others, not how to use AI, but what it's doing to the human mind. Their talk explores how cognition is shifting, which human traits become more valuable as AI takes on complexity, and what genuine human AI partnership actually looks like. As always, doors open at 6:30pm and talks start at 7pm sharp. We have a tight capacity for this event, so please RSVP as soon as you can to secure your space. **Agenda:** **[Marcello Urbani](https://www.linkedin.com/in/marcello-urbani-4730b75/?skipRedirect=true) @ [Nova Intelligence](https://www.novaintelligence.com/)** "**Bringing Agentic AI to the SAP Ecosystem"** Most enterprise software wasn't built with AI agents in mind — and mainstream agents weren't built for enterprise software. SAP is the sharpest example: code lives in the system, not a filesystem, and git-based workflows simply don't apply. Nova closes that gap — an agentic assistant that speaks SAP natively. This talk covers the mismatch problem, how we designed Nova around SAP's environment, and what it looks like when an AI agent finally works as well on SAP as it does on mainstream systems. Bio: Marcello is a software engineer with over two decades in the SAP ecosystem, most of them building DevOps tooling at Basis Technologies. Last year he joined Nova Intelligence to focus on AI applied to SAP systems. An active open source contributor, he is best known for abapfs, a VS Code plugin that enables ABAP development directly in the editor. **[Adel Rahimi](https://www.linkedin.com/in/adelr/) @ [WeBuild-AI](https://www.webuild-ai.com/)** "**Small Language Models: Practical AI for the Real World"** Large language models have dominated the AI conversation, but a quieter revolution is underway. In this talk, we'll explore the rise of small language models and why they matter now more than ever, from reduced infrastructure costs to data sovereignty and the ability to run AI on-premise or at the edge. We'll dive into the techniques that make small models punch above their weight, including distillation, quantisation, fine-tuning and low-rank adaptation. Whether you're navigating regulatory constraints, working with limited compute, or simply looking for a more practical path to production AI, this session will give you the tools to think smaller and smarter. Bio: Adel is a Principal Engineer at Webuild-AI. He has a decade of experience in building and scaling AI and ML solutions at different industries and different company sizes, ranging from series A to unicorns and more recently he was a Sr. AI Engineering Manager at Procter & Gamble. He has also published several research papers in the areas of AI Explainability and NLP and is an advocate of safe and explainable AI. **[Elliott Almeida](https://www.linkedin.com/in/elliott-almeida/) @ [AWS](https://aws.amazon.com/)** **"The Cognitive Partnership: How AI is Reshaping Human Intelligence"** This session explores the profound psychological transformation at the intersection of human cognition and artificial intelligence. Moving beyond tactical implementation, we examine how AI is fundamentally altering our cognitive identity and which human psychological profiles naturally thrive in AI collaboration. Drawing on the "Missing Middle" philosophy and the tension between cognitive offloading and scaffolding, we investigate the paradox of augmentation: as AI handles increasingly complex cognitive tasks, what uniquely human capacities become more valuable? We hope to see you there for another great AI filled evening! **Sponsors...** The AI Exchange is brought to you in partnership with[ LinuxRecruit](https://www.linuxrecruit.co.uk/) and[ AWS.](https://aws.amazon.com/) LinuxRecruit is building the next wave of Tech Unicorns in Europe.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
