PyData London - 107th Meetup
PyData London - 107th Meetup
**Venue:** Riverbank House, 2 Swan Ln, London EC4R 3AD **Please note:** 1\. 🚨🚨🚨 A valid photo ID is required by building security\. 🚨🚨🚨 2\. 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. [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.

London Polyamory Monthly Meetup
London Polyamory Monthly Meetup
We are back to in person pub every month! At the Sir John Oldcastle Pub right by Farringdon station. Reachable by three tube lines, national rail and bus routes. First Tuesday of every month. PLEASE NOTE WE ARE NOT A SEX/SWINGERS CLUB! PLEASE READ THE GROUP DESCRIPTION BEFORE JOINING While this is a free event, I'd like to request that those attending the social make a voluntary donation of £1 to help cover the admin costs of Meetup.com: https://ko-fi.com/ldnpolyam This meetup group is for anyone who is interested in openly and honestly loving more than one partner - you may call yourself polyamorous or non-monogamous or any other label you prefer, but if you are interested in having, or currently have multiple romantic and/or sexual relationships where all concerned are consenting and in full knowledge, you are welcome to come along and chat with others who understand those choices. This is NOT a dating group of singles! If you are actively looking for a partner, that's fine, but the group is not set up for the purpose of matchmaking, and some of our members are pretty "polysaturated" (i.e. they have as many relationships as they want and are not looking for more!) I'd hate for anyone to come along expecting that everyone there is looking for new partners and then be disappointed. If you are looking for new partners, look out for things like Poly Speed Dating nights, Poly Cocktails and try looking online at, for example, okcupid.com. If you receive unsolicited "let's meet" or other predatory messages from a member, please forward them to the admin team. We aim to be a safe space for everyone. Come along and talk to others about how they found their partners, too, if you like. We are a friendly group and not known to bite. ;-) You can find us by looking for the plush and inflatable parrots on our tables, or for Angus' blue hair. Alternatively ask at the bar for "Angus' group", "The poly group", or "the parrot people". We're usually in the area towards the back of the pub.

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.

 Fresha Data Meetup: Sweet Streams Are Made of This
 Fresha Data Meetup: Sweet Streams Are Made of This
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

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 :)
