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. They have performed together in a wide variety of shows and formats for many years, as well as teaching and facilitating workshops, classes, and training sessions. #### Avril Avril is an improviser and actress who has been performing improv for over 12 years.

This month we're doing something a bit different. Edward Boggis-Rolfe has very kindly offered to host us at the moorings where he has a boat, just up past Tower Bridge. We'll have access to a small event space, right on the river, which is covered, but outdoors. We'll have a BBQ going, serving sausages, and free drinks. The cost of the food and drink is being covered by Undo - so thanks to Undo, too! But rather than just be a social event, we do want to include some C++ content, too. We'll have access to a screen and projector - but whether we'll be able to use them depends on the weather! So we're inviting anyone that wants to give a **lightning talk** to let us know. The one caveat is that you'll need to be prepared to give it *without slides* if we can't use the projector (we should have audio, at least). As an extra incentive we'll be holding back a few places for people who can give talks. Spaces will be limited overall, but if you do a talk your place is assured! So submit your ideas here: [cppldn.uk/speak](https://philnash.typeform.com/to/pJVp7s) 5 minutes, something related to C++, slides optional. Go!

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.

🎉 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?

Zero fluff. As many demos as we can. ​Hack Night at Tessl is a London evening for people who would rather build than posture. You show up with an idea, find a team if you want one, spend a few focused hours shipping with a DJ in the background, and demo what you made before the night ends. Then we head to the pub. ​**When**: May 13\, 2026 \| 4:00 PM \- 8:45 PM BST **Where**: Tessl office, London ## Here's How It Works ​**4:00 PM - Doors Open** Check in, grab food, meet other builders, form groups, (or solo hack if you want) and decide what you're making. ​**4:30 PM - Opening Context** Quick welcome from the host and venue partner so everyone knows the flow for the night. ​**5:00 PM - Short Technical Remarks** If there are host or sponsor remarks, they stay short. The point is to get useful context, then get people building. ​**5:30 PM - Build Time** Heads down. Music on. Ship something. Use the time to test an idea, explore a tool, or finally build the thing you've been sitting on. ​**7:30 PM - Demo Time** Show what you made. Get feedback. See what everyone else shipped. ​**8:45 PM - Wrap Up** Final demos, shout-outs, and a clean finish to the night. And of course, Pub! We're heading to a pub nearby for a pint and a proper debrief. Come if you want to keep the conversation going.

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 a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
