Elixir London Meetup; February 2026 edition. All are welcome. **Session 1: Anton Borisov - Distilling Kafka's Binary Protocol into Elixir** We'll trace a produce request to show what any Kafka client has to get right. In the BEAM ecosystem, erlkaf wraps librdkafka, brod implements the protocol in Erlang, and [kafka_ex](https://hex.pm/packages/kafka_ex) goes pure Elixir. Kafka_ex's approach is to generate serializers at compile time from Kafka's own schema definitions: plain structs, pattern matching, structural boilerplate isolated from the logic you actually think about. That design is what let us jump two major versions ahead and adapt to significant protocol changes. Let's dig into the idea, the code, and the tradeoffs. **Session 2: Evadne Wu** **\- JavaScript Execution Strategies in Elixir\-based Agent Frameworks** We'll look at integration points between elixir agents (in the AI fashion) and JavaScript execution, and all the foot guns involved. *The event is kindly sponsored by* [Fresha](https://www.fresha.com). **Time** Doors open at 18, start at 18.30. **Venue** Fresha The Bower, 207-211, Old St, Tower, London EC1V 9NR **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.**

This is a smaller version of our usual StitchUp meetings, hosted in my studio in Bloomsbury. Made for a smaller group in a more quiet setting. Tea and water, biscuits will be provided. **Welcome to StitchUp** – a welcoming social group that embraces individuals of all skill levels, providing a shared space for crafting in a social setting. **Bring your current project**, whether it's knitting, quilting, embroidery, or any other textile craft. Work on your project or piece while having a chat with us. Some people knit, some people mend or just join the conversations. If you are starting new, I’m sure we can give you tips, but generally this is not a class or workshop and you will have to bring your own materials.

Hi friends, Off to a great start! Our first event made one thing clear, we got together because we all agree it’s surprisingly hard to meet others in our field outside of work or a commercial conference. As a smaller group, we make meaningful connections with like-minded actuaries and quants. Lifelong friendships are forged along the way! Whether you're a veteran, a rising star, or simply new in town and want to expand your social circle, get into the insurance and banking space, or see a friend you know, this is the place to be! No guest speakers nor rigid agenda, just a casual meetup and lots of fun conversation! 🥳 We're also on Luma, so please follow us there too! [https://luma.com/friendly-actuaries](https://luma.com/friendly-actuaries) See you soon! NOTE: Please remember to bring your ID with you, as all guests must be of legal age to enter the venue. **About Us** We're a sister group of [The Friendly Data Meetup London](https://www.meetup.com/the-friendly-data-meetup/?eventOrigin=home_groups_you_organize), a bootstrapped 2000+ person group (and still maintains that small cozy vibe!). This one is focused on actuaries and quants :D 🤗 Welcome actuaries, quants and friends! Sometimes, it can be difficult to make friends within the field, and that's what we're all about! We're a group of like minded individuals who understand the highs and lows of working in finance and insurance. ✅ Our primary goal is to have higher quality conversations that are more meaningful, with smaller groups so that we get to spend more attention on each individual. 💯 If you're already reading this, you're definitely welcome! We welcome everyone, whether you're already in the field, looking to get started or just curious! 🗨️ Bring your friends, bring your plus ones, we're all just here to have a good laugh and a good chat about the world, even if it isn't always about our work. **Our values:** 📖 Openness - We welcome everyone 🤝 Trust - Build long-lasting friendships together 💝 Care - Be kind to others and help each other out **Who it's for:** \- Life Actuaries \- Non\-Life Actuaries \- Health Actuaries \- Pensions Actuaries \- Reinsurance Actuaries \- Quantitative Analysts \- Quantitative Traders \- Investment Bankers \- Portfolio Managers \- Financial Engineers \- Entrepreneurs\, Contractors \- Anyone who works with Insurance\, Pensions\, Hedge Funds\, Investment Banks\, Asset Managers etc\. \- Anyone looking to get into the space \- Friends **How to Make the Most of the Meetup** The Friendly Meetup for Actuaries and Quants has one simple purpose: meaningful connections. We're not just a community of people, we're friends who get invested in each others lives. We check in on our friends regularly, and personally. So come and join us, more than just once or twice! **Code of Conduct:** The Friendly Meetup welcomes all genders, nationalities, ethnicities, backgrounds, identities etc. There is a strict no discrimination policy in adherence to our code of conduct and our guiding principles. We maintain a zero-tolerance policy for hateful or antisocial behaviour. In short, be kind to others. Do not insult or put down others. Behave professionally, don't make others uncomfortable. Remember that harassment and sexist, racist, or exclusionary jokes are not appropriate for The Friendly Meetup.

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.
