CoffeeScript

Sorry, no events UFN until a stand-in host is found to temporarily host this event on Mondays and Thursdays (see message to members 24 -8-2021). ................A nice coffee shop near Oxford Circus for the group's twice a week coffee shop meetup when there's a host to host the event. Normally there would be a Central London Group sign on one of the tables. I phoned the coffee shop twice (2022) and both times they confirmed that they're open till 8pm. Any questions my phone number is 07706964277 or email ysi240@yahoo.com ...........Bill (organiser) Again, sorry no events until a stand in host is found as I'm still temporarily not living in London. No membership fees for this group by the way and all events free.

Exited for this event where we'll have the amazing **Manfred Steyer** joining us **in person** talking about how to bring structure to Agentic AI\*\*!\*\* As usual there will be food, drinks and swag thanks to Revolution Technology and Angular.Love :D See you all soon! **AGENDA** • **6:00 pm** Networking/Food • **7:00 pm** Agentic UI Requires Standards: How AG\-UI\, A2UI\, and MCP Apps Work Together \| **Manfred Steyer** • **8:00 pm** Networking **Agentic UI Requires Standards: How AG\-UI\, A2UI\, and MCP Apps Work Together \|** **Manfred Steyer** Agentic AI promises systems that can plan, act, and use tools. In practice, integrating these capabilities into the UI often leads to tight coupling between frontend, agent logic, and specific backend technologies—resulting in vendor lock-in and limited flexibility. This session shows how open standards bring structure to Agentic UI. It introduces AG-UI, A2UI, and MCP Apps, and explains how they work together across system boundaries: AG-UI decouples the frontend from agent implementations, A2UI enables structured and dynamic interfaces, and MCP Apps provide reusable, backend-agnostic capabilities. Together, these standards enable flexible, decoupled architectures that remain stable even as underlying technologies evolve. **More about our speakers:** **Manfred Steyer** *Trainer, consultant, and programming architect with a focus on Angular, Google Developer Expert (GDE) who writes for O'Reilly, the German Java Magazine, and windows.developer. Regularly speaks at conferences.* Many thanks to our sponsors tonight, **Metro Bank** for hosting us and **Revolution Technology** for the food and drinks and **Angular.Love/House of Angular** for the swag :D **Revolution Technology** are a Tech Recruitment Agency who specialise in Software Engineering, Data, Infrastructure and Testing.

Our next English Conversation Café will be on **Monday 11th May 2026 at** **7:30pm**! Topic for the evening: To be confirmed You will have an opportunity to practice your English and meet new people, through conversation topics and games. This event is mainly for learners of English, so we kindly ask native speakers to give priority to others. The venue is **downstairs** in Costa Coffee, 3 Southwark St, London SE1 1RQ which is a 1 minute walk from London Bridge Station. This is a **free** event, you will not be expected to pay for anything. You will also be able to have a free drink and cake. The café is run by a group of volunteers from [The Globe Church](https://www.globe.church). Please sign up if you would like to attend. If you have any questions please ask us using Meetup. Numbers are limited so please only sign up if you are going to come and change your response if you can no longer come. Look forward to seeing you soon 😊

Let's go with the flow and do this amazing 10 mile walk in the stunning Hampshire countryside ! Things to bring : packed lunch, water, snacks etc and waterproof jacket and walking shoes/boots/trainers. We shall buy group train tickets at 10am for the 10.30am train that arrives at Haslemere at 11.21am. Train ticket: Return to Haslemere Or you may decide to drive. Lunch stop will be by a pub in Fernhurst. You should have adequate and appropriate insurance for this type of activity and be able to walk 2.5 miles per hour. We shall have a drink at the end of the walk. Likely train back from Haslemere at 5pm that arrives in London at around 6pm. Please only post photos of others with their consent. My no is 07714250849.

Writers, learn more about writing fiction well through our constructive feedback, comradery and lively discussion. You'll be amazed at what you can learn by listening, and sharing your own words once you feel ready. No pressure. In our regular feedback workshops, we have three writers sharing a sample of their writing for immediate feedback, advice and encouragement. Critique is led and moderated by your host Lisa Goll. Listening to the writing of others and the feedback their piece receives on the night is how we learn. We've been running these sessions since 2010 and there's a reason they fill up so fast! Usually, our workshops are limited to a group of 15 writers in total. Three reading; the rest listening, commenting and giving feedback. For people reading, pieces must be **3,500 words or less** as you'll have about 45mins for reading and discussion on your excerpt from around the table. Most people bring 3,500 words from their novel or a short story of all genres and styles. If you'd like to read, please **post a comment below**. ***You must have booked your place before making a request to read.*** If you are reading, **please bring enough printed copies (at least 10)** of your pages so members can make additional feedback/editing notes for you during the reading. All copies will be returned to you after the feedback has concluded. New members are always welcome in these groups. Most people come along to a few sessions before offering feedback, commenting or requesting to read but it's up to you. If you want to read right away, great, but if you want to come along and see how we roll first, that makes sense too. Again, you'll be surprised by how much you can learn from others by listening to the pieces and their feedback. After the workshop, most of us head to the bar for a social drink or two and extended conversation about the highs and woes of writing. **TICKETS:** £15.00 and please follow the steps to pay via PayPal when you RSVP. Ticket price pays for workshop fees, planning, hosting and organising which involve time and effort. A community of 4,500+ writers takes time to manage. PLEASE NOTE: Refunds or credits will only be provided if the workshop is cancelled by us. We cannot offer refunds or credit for another session if you decide not to attend on the day. **Please change your RSVP if you no longer plan to attend.** We often have people on the waiting list and we'd hate for others to miss out. Location: **The Sutton Arms EC1,** 6 Carthusian St, Barbican, London EC1M 6EB. Closest stations are Barbican, Farringdon and Moorgate.

We are back! This is going to be a monthly IN PERSON meet up in London. A very big thank you goes to Accurx who is hosting us in their amazing Shoreditch offices. This will include access to facilities including coffee! 😻☕️ **Want to know more? 👇** As with all CoffeeOps, this is an interactive, chatty, build your own adventure type of meet-up. Instead of booking in experts to *learn* *from*, we gather a group of practitioners to ***learn*** ***with***. We have been running for over 4 years now and often get feedback that this is the most useful meetup people join! The event is approximately 90 minutes and always starts by brainstorming topics to discuss. The group then votes on the most relevant/interesting to them and we then cycle through the topics trying to discuss each deeply, but in a time bound slot. To get an idea of topics, you can check out our remote board [here](https://easyretro.io/publicboard/h404NF84Uje4tCcxpJdHr4Ycs9B3/a4a35d2b-181b-409b-832e-a729be1af79c). The general gist is anything is fair game, though we tend to revolve around software delivery and definitely lean towards the more Ops-y or DevOps-y side of things.

🎉 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?

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 .

Join us for our next Emacs London meetup held at University College London (UCL). A projector will be available, if anyone wants to give a presentation and/or if helpful to share Emacs tips, for some collaborative debugging, etc. We might head to a pub for a drink and/or a nibble afterward. Emacs users of all levels welcome! Interested in Emacs but not really a user? You're more than welcome too! **Call for presentations** Fancy talking about your favourite Emacs package? Proud of your latest Emacs Lisp hack and you want to tell everybody? Anything parenthesis-related that's bugging you? There'll be a monitor waiting for you for a short presentation!

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? 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./)
