Decentralized Systems & Applications

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.**

You’ll get to experience the style, exercises and atmosphere firsthand before deciding whether deeper training is right for you. The workshop stands alone - you’ll still leave with practical tools, insights and the option to practice doing some speaking (if you wish) - and if you feel drawn to continue, attendees receive an exclusive discount towards the full programme (normally £498). We always with fun, ice breaker warm-up games to ease you into the session, followed by learning some simple public speaking technique exercises and finishing with some (optional) opportunities to practice doing some impromptu speaking in front of the group. The class will also include some group discussions to learn more about why we struggle with public speaking, and what solutions we can use to help us. Our principles are grounded in authenticity. Our approach to helping people overcome their fears is done through encouraging participants to drop the personas they wear in their day-to-day lives in order to express themselves with honesty, and discover their natural speaking style. We’re big fans of embracing vulnerability and strongly believe it’s a strength, not a weakness. Only through vulnerability do we drop our guard and communicate in a way that truly connects to others. **The Session will include:** \- Why we struggle with nervousness when speaking in public \- Our approach for embracing and overcoming these feelings \- Practical techniques to help you come out of your head and speak using your intuition \- A chance to practice delivering a short impromptu speech \- And much more\! \*\*Secure tickets HERE by [signing up on our Eventbrite page](https://www.eventbrite.co.uk/e/free-public-speaking-class-in-london-tickets-151793471359)\*\* **About our teachers:** We have been running workshops since 2014. We have trained 10,000+ people. Our teachers compete in public speaking tournaments, have a mixture of traditional and improv acting training, studied various meditation and mindfulness techniques and are passionate about human psychology and behaviour. **Testimonials from past students:** "Definitely the best public speaking workshop I have been on!

Our society celebrates extrinsic success; confidence is presented to be smooth, slick, suave and charismatic. Because of this we neglect parts of our personality, our feelings, our idiosyncrasies, our uniqueness, our quirkiness and ultimately our vulnerability in pursuit of becoming confident, according to what society deems as confidence. However, we risk becoming ‘well-rehearsed robots’ and not sincere individuals, who aren’t afraid of expressing their humanness. Our approach offers a very non-conventional way of become an empowering and inspiring communicator. **Our Previous Brand (Public Speaking London):** **[https://www.youtube.com/watch?v=Rl7dAKFp1qs&t=98s](https://www.youtube.com/watch?v=Rl7dAKFp1qs&t=98s "https://www.youtube.com/watch?v=Rl7dAKFp1qs&t=98s")** **Contact details:** **[https://schoolofconnection.org/](https://schoolofconnection.org/ "https://schoolofconnection.org/")** Email: hello@schoolofconnection.org Phone: 020 3151 9908

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.

The Databricks London Meetup is back after a short break, and we’re looking forward to bringing the community together again for another friendly, in-person evening of data, AI, and good conversation.

Building predictable, safe, manageable, testable agents that integrate with existing enterprise systems is critically important to us all. ​In this session, Rod Johnson will show how JVM developers can be central to unlocking the business value of agentic AI, using the Embabel agent framework: [https://github.com/embabel/embabel-agent](https://github.com/embabel/embabel-agent) Embabel is an innovative framework for Java and Kotlin developers, seamlessly integrated with Spring. Built in Kotlin, it aims not to play catchup with Python frameworks like Crew AI, but to leapfrog them to be the best agent framework, period. ​Embabel innovates in several ways. It introduces a planning step that maximizes autonomy while maintaining determinism and safety. It is type safe, ensuring excellent toolability and avoiding errors in prompts. It enables developers to use a rich domain model, defining not just types but behavior exposed to user code and to LLMs as tools. ​ Read more about the [vision](https://medium.com/@springrod/the-embabel-vision-967654f13793?utm_source=luma); and also the call to action for Java developers in recent Devoxx keynote: [https://www.youtube.com/watch?v=dbx1_P7W1DM](https://www.youtube.com/watch?v=dbx1_P7W1DM&utm_source=luma) **​Rod Johnson, Creator of the Spring Framework and Embabel Agent Framework** ​ Rod Johnson is a developer, author, entrepreneur and advisor.
