Programming in R

A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it. We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different. Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part! Who knew getting fit could be this fun? **HOW TO BOOK**: **It's essential that you book onto sessions via our website, using the link below**; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals.

## Ticketed Event - please register via Eventbrite! IF THIS IS YOUR FIRST EVER DROP IN WITH US, YOU ARE IN FOR A TREAT! - Free class :) However, you will have to reserve a ticket via EVENTBRITE [Ticket link ](https://www.eventbrite.co.uk/e/gentle-improv-drop-ins-this-week-physicality-first-class-free-tickets-1986219389662?aff=oddtdtcreator) ## This week: PHYSICALITY ## In this session we explore **physicality** and **Improv**. Our bodies are a great way to communicate, we will explore how the body can be used as a tool for expression, storytelling and communication. We will discover new ways of communicating through play and movement without relying on words. ## Overview Improv drop-ins suitable for beginners. A fun and supportive space to help you boost your spontaneity, imagination, and collaboration. **New to improv or already tried some and want more?** Don’t worry — we have you covered. #### Our Drop-Ins Improv is the art of making things up on the spot and feel immensly proud of it as there is no judgement. Our workshops are designed to be gentle, fun and inclusive. Being on the spot can feel scary and overwhelming. We make sure that you feel supported and at ease at all times. Improv is an amazing tool to **boost your confidence and ability to connect to other humans**, it helps you be creative and let the inner judge go and sip a tea whilst you have fun discovering how freeing being sponteanous can be. Our weekly drop-in classes explore both general topics and specific areas of improv. Story-telling, emotional connection and creative collaboration are the key aspects we focus on, with exciting niche topics designed to stretch you in a safe and playful environment. **Stepping out of your comfort zone should feel fun and exciting** \- we make sure you feel supported and encouraged in the best way possible\, while connecting with others and creating a bit of magic together\. These classes are open to all, **our gentle approach specifically focuses on people who struggle feeling confident in social settings**, however, if you have done improv before, you will certainly find joy coming to our drop-ins. The first half of the lesson we will focus on group and exercises in pairs The second half will be more scene-based where you can showcase your unique self. No pressure to perform. You will be amazed how you will shine with little effort. The drop-ins run either Mondays or Tuesdays from **6:30pm–8:30pm** and are designed as stand-alone classes, so you don’t need to worry if you miss a week. #### What is improv, you ask? Improv is creating something in the moment — unplanned and unscripted. It’s about listening and building something together with others: the ultimate collaboration. Improv is also a great tool for enhancing creativity and for life in general. It encourages spontaneity and connection in a playful, non-judgemental way. #### Who We Are Karo and Avril have over **20 years of cumulative experience** within the improv community.

🎉 Come along to the London Scala Talks! 🎉 In this event you'll hear from Caroline Morton and Katrina Petrevice. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Katrina Petrevice: Caching in Scala using Ref 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan and vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ Caroline Morton: Accidental Functional Programming in Rust (From an Epidemiologist's Perspective) 8:30pm - 🥤 Socialising: Grab a drink and let's discuss the talks. 9:00pm - 🍻 Join us in a pub to discuss the talks! 🌐 **This event may have a live stream** Watch this space for more details. **🗣️ Katrina Petrevice: Caching in Scala using Ref** Caching in memory is often one of the first strategies used to improve system performances. However, implementing caching in a purely functional way introduces unique challenges, specifically around state management and testability. In this talk, we will look at how to utilise functional programming principles with [Ref](https://typelevel.org/cats-effect/docs/std/ref), while maintaining clarity and composability. We will also deep dive into some common pitfalls and look into practical ways to test Ref effectively. ⭐ Katrina Petrevice ⭐ Katrina comes from a non–computer science background and was first introduced to Scala while working at JPMorgan. She credits much of her Scala knowledge to hands-on experience within her team, where she works on building and maintaining data pipelines and managing data systems. Since then, she has developed a strong interest in functional programming and now co-leads the Functional Programming Group at JPMorgan, where she helps share knowledge and foster a community around these ideas. **🗣️ Caroline Morton: Accidental Functional Programming in Rust (From an Epidemiologist's Perspective)** I don't have a background in functional programming - and I never set out to write it. But somewhere between writing trait-based epidemiological pipelines, composing data transformations, and leaning hard on Result, enums, and pattern matching, I started hearing from others: “That's pretty functional.” In this talk, I'll explore what it means to write “functional-ish” Rust as someone solving real-world scientific problems. I'll walk through the patterns I reach for - like chaining iterators, avoiding shared state, and embracing expressive types - and reflect on which functional programming ideas emerge naturally in Rust, even if you're not trying. I'll also share how designing for epidemiologists - most of whom are used to chaining functions in Python (like Pandas) or R - has pushed me toward creating ergonomic Rust APIs with Python and R bindings. These tools aim to feel familiar to scientists while leveraging Rust's power and safety under the hood. This is a talk for functional programmers curious about Rust, and for Rustaceans wondering if they've been functional all along. No formal theory required - just real code, real use cases, and a pragmatic perspective from someone building public health tools in Rust. ⭐ Caroline Morton ⭐ Dr. Caroline Morton is a medical doctor, epidemiologist, software engineer, and PhD candidate specialising in synthetic data, epidemiology, and Rust. With 60 peer-reviewed papers and two books on software, she combines deep technical expertise with a commitment to improving scientific workflows. Caroline co-founded the first [Women in Rust](https://www.meetup.com/women-in-rust/) group, fostering diversity and encouraging more women to explore opportunities in systems programming. She leads an open-source project improving codelist management in epidemiology using Rust, creating efficient, reliable tools for health data research. Her PhD focuses on synthetic data methods for epidemiology, particularly using Rust to generate large, realistic datasets. A strong advocate for open science and reproducibility, she contributes extensively to improving software practices through publications, workshops, and open-source projects. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

**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.

The aim is to learn a little more than before you started. This event is for those new to coding through to more experienced developers. We organise into small groups (2-4) people and write code to solve challenges great and small, chosen by those at the event. We aim to ensure someone in your group has some Clojure experience, so you shouldn't feel lost (well no more than all developers do when Stack Overflow is broken).

Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency. Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s LJC talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” video or Stuart Halloway “Radical Simplicity” video .

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 **⚡️ Interested in giving a talk? ⚡️** Have you ever considered presenting on your Elastic use case?

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.
