**The Unscented Transform: theory, extensions and practical application to Bayesian inference** We are delighted to have John Whitamore back at the Bayesian Mixer. Please register here: https://www.tickettailor.com/events/bayesianmixer/2154878 **Abstract:** How can we perform Bayesian inference without resorting to slow random sampling methods? Isn't there a nice, pragmatic way to use the geometry of a problem to use only a very small number of samples, placed deterministically? Isn't there a good, straightforward way to implement Bayesian models in practical settings? This talk explains the real-world problems that can be solved by the Unscented Transform. It begins with an intuitive introduction to Bayesian methods, discusses the Unscented Transform and connects the ideas to geometry, finite elements analysis and deep learning. **Bio:** John Whitamore is a Senior Data Scientist at Simply Business, a leading UK InsureTech firm. He has previously served as Head of Data Science for a leading food retailer, as Head of Trading and Systems for an investment management company and as Global Head of Convertible Bond Trading for a European investment bank.

MCP is changing how developers build with AI, but we're just scratching the surface. Join us for an evening of talks that go beyond retrieval to explore what's actually possible when you give agents real tools, real constraints and real APIs. **Agenda** ​6:00 PM - Doors open, registration and networking ​6:10 PM - Welcome (Upsun & Cloudflare) ​6:20 PM - MCP: Context is Everything! - Carly Richmond, Elastic ​6:45 PM - Sandboxes: how to limit agents so we can use them more - Patrick Dawkins, Upsun ​7:00 PM - Break (Food & Drinks) ​7:30 PM - Cooking with MCP in VS Code - Liam Hampton, Microsoft ​7:55 PM - Efficient tools with MCP code mode - Confidence Okoghenun, Cloudflare ​8:15 PM - Open networking and drinks ​9:00 PM - Close 🗣️ ​**Talks** ​**MCP: Context is Everything! - Carly Richmond (Developer Advocate Lead, Elastic)** ​MCP is a powerful tool for giving LLMs capabilities to not just retrieve information, but to automate key actions based on relevant data. Let’s see how it can be used for retrieving relevant context and other activities such as observability. ​**Efficient tools with MCP code mode - Confidence Okoghenun (Senior Developer Advocate, Cloudflare)** ​Traditional MCP approaches choke on context windows: Cloudflare's 2,500+ endpoint API would require 1.17 million tokens. Code Mode flips the script by having LLMs write code against typed APIs instead of making direct tool calls, achieving 99.9% token reduction. Come learn how code mode works and how to optimize your MCP tools with it. ​**Sandboxes: how to limit agents so we can use them more - Patrick Dawkins (Principal Engineer, Upsun)** ​We want our agents to run longer and use more tools, but we're hampered by constant prompts for approval. Sandboxes are the practical middle ground: isolate the agent so you can stop watching every command and let it work. This talk covers what "sandbox" means, who provides them today and the Linux primitives that let you build one yourself. ​**Cooking with MCP in VS Code - Liam Hampton (Senior Cloud Advocate, Microsoft)** ​In this session Liam will show you how VS Code is fully supporting the MCP spec, from MCP Apps to sandboxing and elicitations. 📅 **Date and Time:** Thursday, May 14, from 6:00-9:00 PM 📍 **Location:** Cloudflare Address: 6th Floor, County Hall/The, Riverside Building, Belvedere Rd, London SE1 7PB, UK 👉 You can also register here: https://luma.com/eb8j6lhu ⚠️ Please make sure you provided your full name (no nicknames or abbreviations will be allowed) and to bring your ID card as it will be mandatory to show it upon check-in to security.

Reportage photography or visual narrative photography is the art of telling the story of an event or location through photographs. It is based on photojournalism and when carried out properly, reportage photography will provide a comprehensive collection of photographs that will form a story of the subject.

It is going to be challenging but also full of discovery. You will learn how to report and tell your story from beginning to end and then given a brief and a series of exercises to help you tell your story. WHAT YOU WILL LEARN * How to create a visual narrative * What makes a good story and how to show it visually * How to tell a story with a series of photographic images * Improve your composition skills to create impactful images EXPERIENCE LEVEL * Beginner/Refresher EQUIPMENT * Any camera including mobile phone * Any lens CONTACT * Alex 07956 264049 VENICE PHOTOGRAPHY WEEKEND - Oct 2026 [https://www.meetup.com/londonphotographic/events/313109100/](https://www.meetup.com/londonphotographic/events/313109100/) UPCOMING EVENTS [www.meetup.com/londonphotographic/events](http://www.meetup.com/londonphotographic/events)

Today we'll be looking at the work of the Italian artist Caravaggio. Caravaggio adopted *chiaroscuro* in his paintings in the 16th century- his work beautifully combines a realistic view of the human state- physical and emotional- with a dramatic use of lighting. *Chiaroscuro* is an Italian term referencing the contrast of light (chiar) and dark (oscuro) to model three-dimensional forms. It’s a style that has quite dramatic results and one that photographers can learn a lot amount about lighting from studying. **Join us for a workshop in 2 parts:** * Informative session on the incredibly interesting life and work of Caravaggio * Shoot chiaroscuro style * We will also discuss street photography tips EQUIPMENT: * Any camera * Any lens such as a standard 18-55, 24-70mm etc. OTHER ESSENTIALS * A fun and experimental attitude!

Many governments are now pushing age verification and VPN restriction laws, lobbied by Big Tech companies, with no visible popular demand for it. Is that truly to "protect children", or is it better explained by desire to control and censor online speech, while appeasing their corporate donors? Let's discuss the future of the Internet, freedom from censorship, privacy vs. security trade-off, and other related topics. To kick off the conversation, we will look at Cory Doctorow's essay on age verification and "Online Safety Act" called ***[“Privacy preserving age verification” is bullshit](https://doctorow.medium.com/privacy-preserving-age-verification-is-bullshit-0aefd53019e0)***. *<...>politicians all over the world demanded a kind of impossible encryption: encryption that works perfectly when it’s doing something legitimate, like keeping hackers from pushing malware to your pacemaker or stealing your life’s savings or listening in on you through your phone’s microphone, but also they require that this encryption offer no protection to criminals, drug dealers, terrorists, child abusers, and other miscreants.* *This really is like water that’s not wet.*

**Join Psyfer and Akme for a mind/body/art session.** Hatha flow with Psyfer at 11am. Please bring your own mat. Munk brunch at Ana's Deli from 12pm. Art club from 1:30pm with Akme exploring graffiti, memes and Bitcoin's visual language. Promotional activities related to shitcoins not permitted. No unsolicited photograhy. Peace and love.

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!
