uSwitch is located on the first floor of the ZPG building at 5 Copper Row, London, SE1 2LH, London (Click on the map for directions) What 3 words location: [https://what3words.com/puts.sudden.else](https://what3words.com/puts.sudden.else) The Clojure dojo is a collaborative way to learn Clojure/ClojureScript through practice. 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). Example challenges for the coding dojo are listed on this website: http://www.londonclojurians.org/code-dojo/ Various past exercises have been loaded to [https://github.com/ldnclj](https://github.com/ldnclj/lisp1.5/blob/master/src/lisp1/5.clj) # Approximate schedule: 18:40 Doors open and start collecting suggestions 18.45 Pizza should have arrived 19:00 Quick intros and vote on suggestions 19:15 Break out into groups and start practising 20:45 Gather together for a quick show and tell # What should I bring? We organise into small groups, so if you have a laptop with a working Clojure environment please bring it along (there are lots of online Clojure environments, so you can just use your browser too). # How do I get in to the building? At the glass doors press the buzzer to inform the security guard you are here. Say you are here for the event on the first floor. Is there way to talk with the Clojure community? Why yes. The Clojurians Slack channel is full of friendly people who love to try and help. People based in London are often in the #clojure-uk channel. Sign up for a free account to the Clojurians Slack community via http://clojurians.net/ What is Clojure? 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 .

Hello there! - We'd like to welcome you to Free weekly meetings which take place at the Swiss Cottage Community Centre, 19 Winchester Rd, Swiss Cottage NW3 3NR on Tuesday evenings from 7.30pm until 8.30pm Contacts: Jim Ward: 07956 222098 Mary: 07771 596665 Mary: maryconneelyoneill@hotmail.com With Sahaja Yoga Meditation we normally sit on chairs to achieve yoga, effortlessly & spontaneously. So there is no need for mats and no special clothing required. All across the globe, many are seeking new sources of energy. Meanwhile, the most transformative energy of all is hiding in plain sight, within us. It's natural, sustainable, and infinitely renewable. It's called inner kundalini energy. And everyone already has it — everyone!. It is often likened to an inner feminine or motherly energy which automatically knows about us and what is needed to help us restore balance and harmony within our subtle being. It works spontaneously, effortlessly, organically and cannot be paid for. Sahaja Yoga Meditation is a simple time-honoured technique that lets you tap into that energy and harness its power to become better balanced and better connected to yourself — emotionally, physically, mentally and spiritually. If you're having trouble juggling the challenges in your life, Sahaja Yoga Meditation might well help you manage stress, master your emotions and find solutions to your problems. You may enjoy better health, better focus, and a deeper understanding of the universe and your place in it. Meditation is not just for mystics and monks. Sahaja Yoga meditation is for everyone. Anyone can do it. It's that easy. But with the Sahaja Yoga experience, you'll quickly realise, it isn't your typical Meditations 'R Us type class. It's much more than just feeling peaceful and relaxed. Sahaja Yoga Meditation has many layers, varied and deep. Explore at your own pace, in your own way. Our volunteer experts are always available to help. Ready to plug into your inner energy? A Sahaja Yoga Meditation class is a great way to start. A few minutes of your life may be all it takes to connect to your inner energy and light the path to lifelong transformation. Sahaja Yoga is more than a temporary solution or quick relief — it is a journey, rather than a destination. It's all about energy — guaranteed pure and carbon neutral. You can never have too much of it. The best part? All classes are free. No strings, no catch. Everyone is welcome. Bring a friend, bring your self — all are welcome. We have a web site here in London too which you can visit at: http://www.sahajayogalondon.co.uk

**Discussion overview:** Whether in social life, dating or work, everyone reacts differently when someone gets too close (or too far), physically or emotionally. But how much is too much? When does it become creepy? The answer is often personal, but also influenced by our culture: why do some cultures touch and hug everyone - is it romantic or friendly? Why do some overshare or ask about every little detail in life? And if someone asks for space, is it the end, or just going too fast? In a multicultural city like London where so many different cultures and social expectations meet, understanding different signals such as the need for space and boundaries can help us avoid misunderstandings and interact at the right rhythm. *Join us for a relaxed group conversation where we explore real life, grey areas, and how our different cultures and backgrounds shape our views about key topics.* *Expect real talk, no judgment, and a chance to learn how others see it.* **\*Come for the discussion, stay for the friendships.

A calm, low-key space to pause, breathe, and reconnect with yourself alongside others who understand. The **Queen’s Rise Circle Survivor Check-In** is a gentle, bi-weekly gathering created for women healing from narcissistic, emotionally harmful, or difficult relationships. This is not therapy or a formal workshop. It is a supportive community space where survivors can come exactly as they are. Some weeks you may want to share. Other weeks you may simply listen. Both are welcome here. Together, we focus on small steps forward, emotional grounding, and rebuilding confidence in a safe and respectful environment. This space is survivor-led and trauma-aware, grounded in empathy, respect, and confidentiality. ### Who this is for This check-in is suitable for anyone who: • Is healing after a narcissistic or toxic relationship • Feels emotionally overwhelmed or isolated • Wants connection without pressure or judgement • Is looking for consistent, gentle support between workshops or coaching You do **not** need to be at a particular stage of healing to attend. ### What this space is not • Not group therapy or crisis support • Not a place for advice-giving or fixing others • Not a space for confrontation or debate It is simply a supportive circle for reflection, encouragement, and community. ### What to bring Just yourself. Tea, notebooks, and comfortable energy encouraged. There is no requirement to share if you are not ready. You are welcome to listen, reflect, and simply be present. This is not therapy, but a peer-support space rooted in compassion, safety, and respect. Come as you are. Cameras optional. You are not behind, broken, or failing. You are healing. ***

We're delighted to announce an exciting LSCC event on Wednesday 13th May, in partnership with our friends at Zopa Bank! Join us at the Zopa Canary Wharf office in London for this session and get the chance to flex your architectural design muscles! "So how are we supposed to get great architects, if they only get the chance to architect fewer than a half-dozen times in their career?" — Ted Neward. This quote highlights the need for practice, which is what our LSCC architecture katas provide: a safe, repeatable way to hone your software architecture design skills by simulating architectural challenges. **What's the format?** You'll be split into groups and have a business problem to solve. You'll be tasked with designing a technical architecture to meet that problem context. As with real-life you'll have to manage various trade-offs in your design and interact with a Product Owner to clarify your questions. At the end of the task each team will showcase their architecture and technology choices back to the wider group as part of a group discussion. Whether you're a seasoned coder, software architect or new to the scene, you're invited to share insights, discuss best practices, and learn from fellow participants. No prior session attendance or architecture knowledge is required – just bring your enthusiasm. No laptop is required for this session, we'll provide each group with paper, pens and sticky notes to support the activity. Thank you to the Codurance team that will run the event at Zopa Bank's office.

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. Entry will be first come, first served. We recommend arriving early to make sure you get in. **⚡️ Interested in giving a talk? ⚡️** Have you ever considered presenting on your Elastic use case? We welcome 5-10 minute lightning talks, 45-minute deep dives, and everything in between. If you're interested, please submit via our [CFP](https://sessionize.com/elastic-meetups/) or send us an email at [meetups@elastic.co.](http://meetups@elastic.co./)

🎉 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?

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.

The documentary explores the events and investigation into an unknown person [cyberbully](https://en.wikipedia.org/wiki/Cyberbullying "Cyberbullying") and [harassing](https://en.wikipedia.org/wiki/Harassment "Harassment") teenagers in [Beal City, Michigan](https://en.wikipedia.org/wiki/Beal_City,_Michigan "Beal City, Michigan") using an unknown number via insults and sexual claims. It also explores the increasingly great impact of the harassment on the community, the eventual reveal of the culprit, and the trial that followed. IMPORTANT INFO: I strongly suggest not reading anything about it online before seeing it. It's best viewed with no previous knowledge. This documentary contains crude terminology and deals with cyberbullying, which may be a trigger for some folks. Please be ready to discuss the movie by 7PM. Thanks. Unfortunately, it is only available on Netflix. If you would like to attend but do not have Netflix, say so and maybe we can figure something out.

By popular demand, the group wanted to read and discuss the semi-autobiographical novel by Henri-Pierre Roche, that inspired the Truffaut movie we watched last year. The book is available through the Columbus Library's interlibrary loan system. They reported there are twenty-eight copies available in the state of Ohio. If you have a library card, you can file an interlibrary loan request here: https://www.columbuslibrary.org/library-services/ . There are also used copies available on Amazon and eBay for under twenty dollars. You may want to rewatch the movie after reading the book, so we can compare and contrast in our discussion. The Columbus Library has four copies on DVD, and it's streaming on HBOMax.
