At Workout with Pride, we're all about promoting lasting health and vitality. That's why we're introducing "Pure Strength," a new class focused on enhancing strength and mobility while keeping the excitement of our other offerings. Age brings unique needs, and our bodies demand more focus on mobility and the improvement of tight areas. As we age, maintaining muscle mass becomes crucial. Strength training is essential for both muscle retention and the health of our bones. Our "Pure Strength" class is a deliberately slower-paced approach to our regular strength training sessions. We've carved out specific times for resting and refining movements. We're creating a space where you can concentrate on developing strength, mobility, and confidence, with our renowned flare for fun and inclusivity. This exclusive class is available for a limited number of participants, so don't miss out on your chance to join us in shaping a healthier future for yourself. Together, let's work towards a stronger, more resilient you.

**Join us for a joint meetup with our friends from Qodo and Tessl** AI coding agents are increasingly embedded in production workflows, but their failure modes are often poorly understood, difficult to detect, and even harder to evaluate systematically. ​This session examines how agent-based systems degrade under real-world conditions, focusing on three critical dimensions: reliability, code quality, and security. We’ll look at where current evaluation approaches fall short, how non-determinism and context drift impact correctness, and why seemingly “successful” generations can still introduce latent defects or vulnerabilities. ​If you’re building, evaluating, or deploying AI agents in production systems, this session will provide a grounded view of where they fail and what it takes to make them robust **Agenda** * ​​​6:00pm Venue opens * ​Join us for Drinks and Pizza! * ​​​6:30pm **Hidden Failure Modes for AI Agents** by Nupur Sharma * ​6:50pm Panel Discussion * ​**Panelists** * ​**Simon Maple -** Developer Relations at Tessl * ​**Brian Vermeer** \- Staff Developer Advocate at Snyk * ​**Nupur Sharma -** Solutions Engineer at Qodo * ​**Kunal Kushwaha -** Senior Developer Advocate EMEA at Cast AI **SPEAKERS** **​** **Simon Maple - Developer Relations at Tessl** ​Simon Maple is the Head of Developer Relations at Tessl, and AI Native Dev co-host.

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.**

****Please note: the first 300 RSVPs are free 🎉** **After 300, there will be a small charge of £3.** **This is to ensure no time wasters ✅**** **Hey you!** **Looking to meet kind, fun people from all over the world 🌎 and make genuine new friends?** **Come join us for a relaxed, feel good evening at this new venue ✨🍹** **We’ll chat, laugh, and connect 💬😄, and play some easygoing games to break the ice 🧩🎲** **I’ll bring a few, and you’re more than welcome to bring your favourites too!** **Whether it’s something silly 🤪, clever 🧠, or just fun to share 🎉, it’s all part of the magic ✨** **No pressure, no awkward vibes, no fancy rules 🙌** **Just real people, warm conversations, and good energy, plus a chance to make London feel a little more like home 🏙️💛** **International crowd welcome 🌍 all backgrounds welcome 🤗 and all smiles welcome 😁** **Come as you are 💫** **Bring a game 🎲, bring a friend 👫, bring your curiosity 🌟** **Let’s make it a night to remember ✨🎉** **Khu**

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.

PHP London Pub Social – April 9th, Jack Horner, Tottenham Court Road Join us for an informal PHP London pub social at the Jack Horner on Tottenham Court Road!

Join us both online and in London for a deep dive into how JVM developers can lead the next wave of innovation with agent-based systems. We’re excited to host Rod Johnson, creator of Spring, as he introduces Embabel, a new framework designed to push Java and Kotlin to the forefront of agentic AI. From building safe, testable, and enterprise-ready AI agents to rethinking how Java fits into the Gen AI ecosystem, this session will give you a front-row seat to what’s next. Whether you join us virtually or in person at Tessl HQ, expect an evening of cutting-edge ideas, practical insights, and great conversations with the Java community. Can’t make it in person?

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.

**Caller: Kim Thompson** **Band: Full Moon Country Dance Orchestra** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot.
