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 :)

**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.

May Edition ✨✨! We will be at Kraken Tech (Octopus Energy Group), London office! (in-person only event, no streaming) **Talks:** **Django's GeneratedField by example — Paolo Melchiorre** Learn how to use Django 5.0's GeneratedField through practical examples. This field lets the database compute values automatically based on other fields in your model — a powerful feature that's easy to underuse. Paolo will walk through real-world use cases to show where it fits and how to make the most of it. Paolo Melchiorre is a Python backend developer, Django contributor, and Python Software Foundation Fellow. He serves on the Django Software Foundation board, co-organises PyCon Italia, and is a coach for Django Girls and a navigator for the Djangonaut Space mentorship programme. *** **Django in the Lab: how web development is reshaping behavioural research — Andy Woods** Off-the-shelf platforms can't always keep up with the complexity of academic research. Andy has been using Django since version 1.11 to build tools that can — from coordinating live location-based VR studies to running inclusive diary studies via WhatsApp and auditing immersive experiences for accessibility. He'll share where Django works especially well in academic settings, what surprised him along the way, and why this moment feels like a real opportunity for the Django community. Andy Woods is a Senior Research Engineer-Psychologist at CoSTAR & StoryFutures, Royal Holloway, University of London, and a Django Software Foundation Individual Member. **Want to share your Django or Python knowledge?** We’d love to feature your talk!

Hi folks! Welcome to our May Cloud Native London meetup! Join us to hear from our three great speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube or LinkedIn! 6:00 Pizza and drinks 6:30 Welcome 6:45 The End of Handoffs: Build, Run, Own in One Flow (Alberto Pose, Pulumi) 7:15 You Can’t Patch Fast Enough: What AI-Driven Attacks Mean (Idan Elor, Oligo Security) 7:45 Break 8:00 From Zero to HyperPod: Distributed Model Training on AWS (Anton Nazaruk, Cloud Combinator) 8:30 Wrap up See you there! Cheryl (@oicheryl) **The End of Handoffs: Build, Run, Own in One Flow (Alberto Pose, Pulumi)** AI is changing the shape of team structures. A similar shift to the one that brought dev and ops together into DevOps is now happening as product must also meet the accountability bar. At the same time, tooling has not caught up with "throwing it to Claude/Codex". Engineers are confronted with a choice: trust code and actions they do not fully understand, or... move too slowly. Are these problems fundamentally new, or are there lessons we can draw from the past to adapt and think about what comes next? *Alberto Pose is a software engineer with a soft spot for developer tooling and infrastructure. He is currently part of the team managing the CI/CD pipelines for Pulumi's open source projects. Before this, he spent nearly ten years at Prime Video and AWS. A major highlight of his time there was helping bootstrap the living room device automation team, taking it from a small group effort to a 30 person organisation that brought full automation to millions of streaming devices worldwide.* **You Can’t Patch Fast Enough: What AI-Driven Attacks Mean (Idan Elor, Oligo Security)** Anthropic’s Project Glasswing announcement put the industry on notice. AI has fundamentally changed the threat landscape and the risks facing organizations, and it’s happening faster than most security models can adapt. AI-assisted attackers can now discover vulnerabilities, generate exploits, and launch attacks at rates never seen before, collapsing the window between disclosure and exploitation. In this environment, patching alone is no longer enough. For cloud-native applications, where systems are dynamic and constantly evolving, this creates a new challenge: how do you stay protected when you can’t fix vulnerabilities fast enough? This talk explores how the attacker model is shifting in the AI era, why traditional approaches are breaking down, and what it means to move from vulnerability-based security to real-time protection at runtime. We’ll cover how focusing on exploit techniques enables teams to stop attacks as they happen, including zero-days. *Idan Elor is Field CTO at Oligo Security, where he partners with large enterprises to solve complex application and cloud security challenges. He most recently served as Director of Solution Engineering & Tech-Alliances at Apiiro, where he empowered enterprises to secure their software supply chains. With over a decade of experience spanning application security, DevSecOps, and mobile security, Idan has also held leadership positions at companies like Snyk, Symantec, and HP. His unique background combines deep hands-on technical expertise. A passionate advocate for bridging the gap between security and development teams, Idan is known for his ability to translate complex security concepts into actionable strategies that organizations can actually implement.* **From Zero to HyperPod: Distributed Model Training on AWS (Anton Nazaruk, Cloud Combinator)** You've got a model that works. You just need more GPUs. How hard can it be? That's where the pain starts. GPU availability, infrastructure complexity, and cost are the three blockers that trip up even experienced teams when scaling from single-GPU training to serious distributed workloads. This talk is a practical walkthrough of how to set up distributed model training on AWS - covering the capacity options (On-Demand, Spot, Capacity Blocks, SageMaker Training Plans), when to use each, and a repeatable infrastructure blueprint for compute, networking, storage, and observability. I'll demo provisioning a HyperPod cluster and running a distributed training job with automatic failure recovery, and share the cost levers that matter at scale. Whether you're a platform engineer supporting ML teams or an ML engineer tired of fighting infrastructure, you'll leave with a decision framework and a blueprint you can implement. *Anton Nazaruk is CTO at Cloud Combinator, where he helps companies run GPU workloads on AWS - from early-stage startups to larger organisations doing distributed training at scale. He focuses on making ML infrastructure repeatable, resilient, and cost-efficient.* *LinkedIn: linkedin.com/in/anton-nazaruk* *Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.*
