It's that time of the year again, Rust Nation UK. We are excited to have Rustaceans who have flown in to meet the London community, forge new friendships, and engage in insightful discussions. Tickets are still available for the conference. Community Promo code: RustLDN2026 [https://www.rustnationuk.com/tickets](https://www.rustnationuk.com/tickets) **Community Showcase** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Iason Paraskevopoulos** **Title: Building an OSS Remote Pair Programming App in Rust** **Abstract:** Hopp is a multi-user remote control and screen sharing app designed for fast, natural collaboration. This talk walks through how the system works end-to-end, from cross-platform screen capture and input handling to low-latency video streaming. It covers why we chose Tauri for cross-platform development early on, the headaches caused by WebKit’s inconsistencies and WebRTC issues, and why we are moving towards a Rust-native UI. **David Wood (Rust Compiler Team Co-Lead)** **Title: Extending Rust’s notions of sizedness** **Abstract:** This talk is based on work I am completing upstream as the co-lead of the compiler team and the lead of Arm’s Rust team. It is based on this RFC - https://github.com/rust-lang/rfcs/pull/3729, which is partially implemented. We hope to stabilise the implemented parts before this talk is presented. More Talks to come......

The London Mountaineering Club's weekly club night at Westway takes place every Tuesday. There will be many more of us at the wall than listed on this event. To find us, look for people wearing an LMC T-shirt. This is a friendly meetup for competent climbers (at all levels of aspiration) to find people to climb with. If you have not climbed at Westway before, you will need to pass Westway's safety test before you can climb unsupervised. If you are unsure whether the centre will allow you to climb unsupervised please message the event organiser on Meetup in advance. We may be able to arrange supervision for you to climb without passing the test but this depends on club members being available to supervise and places will be limited. The London Mountaineering Club does not charge for this event but you will need to pay the entry fee to Westway and for any gear hired. Details of the Westway climbing wall are available on the [Everyone Active website](https://www.everyoneactive.com/centre/westway-sports-fitness-centre/climbing/) including [prices](https://www.everyoneactive.com/centre/westway-sports-fitness-centre/?activitySearch=casual%20climb).

Join OutdoorLads popular weekly Thursday Bouldering evening at The Arch in Bermondsey. OutdoorLads London boulderers welcome all members of the LGBTQ+ community You'll be meeting with a supportive group of 5 to 10 plus boulderers who are always happy to introduce complete beginners or solve difficult bouldering problems with enthusiasts. We usually follow up with a pub visit. This event is for members of all levels of experience and all are welcome to come along to any of the sessions. Bouldering is a form of climbing where instead of long high routes, the 'problems', as they are referred to, tend to be shorter and focus on technique, balance, body positioning and sometimes power. Because of this different emphasis, bouldering doesn't have the hassle of climbing with ropes, harnesses and belaying, which makes the activities excellent for newcomers to the sport. If you're a seasoned climber you won't need convincing about the benefits of bouldering, but for those who've never climbed more than a staircase, the benefits are wide ranging: from the physical - improved strength, tone, balance, power and coordination; mental - problem solving, focus, concentration and body awareness; to the emotional - relaxation, a sense of achievement and a feeling that mind and body are working together perfectly ('feeling psyched'). On top of all this, bouldering tends to be a very social sport where you can hang out with mates and each have a go as you feel regardless of what level you climb at.

Elixir London Meetup; February 2026 edition. All are welcome. **Session 1: Bryan Hunt - Faria Data Platform: Building a data platform in Elixir** How to build an ETL pipeline using Amazon Athena, and Elixir: techniques, tools, UX, lessons learned. **Session 2: Christoph Beck** **\- Structured Generation and Logits Processing with Elixir** Ever tried to get a poem from an LLM doesn't contain the letter \`e\`? Large Language Models are kind of amazing and surprisingly unreliable at the same time. Using Elixir's Bumblebee and open source LLMs, you can get much better control over the generation. We introduce you to logits processing, and how it can be used to achieve what ChatGPT can not accomplish. *The event is kindly sponsored by* [Verna](https://verna.earth). **Time** Doors open at 18, start at 18.30. **Venue** Geovation F4, Sutton Yard, 65 Goswell Rd., London EC1V 7EN **Refreshments** Food and drinks will be provisioned on the day. **IMPORTANT**: **If you wish to take photos and post online during the event, please notify organisers first, so that attendees can opt-out from being in photos.**

Join OutdoorLads weekly Saturday bouldering morning event at Vauxwall West - please check our main event page on our website (link in the comments below). We welcome all members of the LGBTQ+ community, and you will be socialising with a supportive group boulderers who are always happy to introduce complete beginners to the sport or solve difficult bouldering problems together. This event is for members of all levels of experience and all are welcome to come along to any of the sessions. Bouldering is unique. There are few sports out there that offer a mental and physical challenge no matter what skill level you are at. Each route consists of several holds that the climber uses, focusing on problem-solving and technical movements to help them reach the top. No two routes are ever the same, and the colour-coded system indicates the difficulty level, so there's a climb for everyone to enjoy! If you have never tried bouldering before, please ensure that you have gone through the centre's safety and induction video beforehand (https://londonclimbingcentres.co.uk/pre-register/) as you will be required to answer a few safety questions when registering at the centre.

*"The day starts with a cockerel crowing and waking Heimdall, the watchman, who blows his horn Gjallir to call the gods. Nature is in confusion and the seals rush onto the land."* Ragnarök Vikings settled in the 9th-C and from 1016 to 1042, England was Danish. Barely a trace remains in this part of the country; however this walk to idyllic Wealden countryside passes through a Viking place. Follow through a door telling the legend of Ragnarök, to find what lies behind. *Hyrst* at the time meant a wooded hill. Sissinghurst Castle garden is famous for its roses. These live behind a National Trust paywall; however we shall see as much of the site as possible from adjacent public footpaths. Outward Travel: Take the train departing 9.43 AM from London Bridge to STAPLEHURST. The return train fare with a Network Card or GroupSave is £14.75. The organiser will be standing in front of the ticket office at London Bridge from 9.15 wearing yellow to act as a focal point for people to arrange group train tickets. Walk start: 10.35 AM from Staplehurst rail station. Bring a packed lunch. Village / pub stop. Circular walk. *How to join?* * The walk is entirely free of charge; * You only arrange for your own travel and pub expenses; * Understand our terms and conditions below (the "IMPORTANT" part); * Understand how to stay safe outdoors, as you will be responsible for yourself. See our quick safety tips: http://www.meetup.com/Free-Outdoor-Trips-From-London/about/ *What to bring* * Plenty of water, 1-2 litres recommended * Enough snacks and packed lunch to keep you energized along the walk * Extra snacks and an extra packed lunch just in case * Rainproof (ideally waterproof) clothing, sturdy shoes/boots you don't mind getting muddy * Spare socks * Walking poles and/or an umbrella :-) * Yourself... * ...and your camera! * Cash for train ticket * Cash for pub at the end of the walk? Feel free to ask any questions in the comments section! IMPORTANT Please bear in mind this is a free of charge, self-guided trip with a hobby group. It is not organized by a business nor any entity with commercial purposes. Any trip details, travel advice, route planning, instructions and other content in our group merely represent our shared personal knowledge, research and suggestions as outdoor enthusiasts. As this is no business, there is no "product", "service" or "package" and also no "tour guide", "operator" or "walk leader". Each participant is responsible for their own safety. Even if some of us are very experienced walking outdoors, nobody assumes responsibility for any kind of injury, damage or loss that may happen. Despite this, we take extreme precautions and all trips we plan are very safe, fun, highly educational and popular. Our experienced members volunteer their time and effort to shape a pleasant and quality adventure for everyone :-) By participating you acknowledge and agree with this disclaimer. Here are our tips on staying safe during outdoor trips: http://www.meetup.com/Free-Outdoor-Trips-From-London/about/ TRAVEL, ACCOMMODATION, INSURANCE Although we provide detailed suggestions, each participant is expected to arrange their own travel - this gives everyone the freedom and choice. Anyone interested in travel or outdoor insurance should also arrange this on their own. As mentioned above we always take extreme precautions, but some people may still feel safer if covered. As most of our trips are confirmed or postponed very close to the event date - heavily depending on the weather forecasts - we advise not to buy this until the last minute. People getting tickets from the same station are encouraged to meet early on the day to benefit from discounts such as GroupSave.

This meetup is a beginner-friendly, hands-on workshop focused on building shaders in Unity using Shader Graph. Instead of slides or theory-heavy lectures, we'll build real shaders together step-by-step. The format is structured but interactive. You'll watch a quick demo, then build each shader yourself with guidance. By the end, you'll have created multiple shaders you can immediately use in your own projects—and understand how to make more. **What to Expect:** * Build 4–5 complete shaders from scratch * Color tints, snow accumulation, scrolling water, dissolve effects, and more * No prior shader experience required * Checkpoint files provided if you fall behind * Resources for continued learning All experience levels are welcome. Whether you've never opened Shader Graph or just want to fill gaps in your knowledge, this is a supportive space to learn by doing. **Food and drinks provided. Join us to learn, build, and level up your shader skills.** I added the Unity project to the repo here - https://github.com/EricJRico/IntroToShaders.git This is what we'll be using for the session.
