A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it. We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different. Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part! Who knew getting fit could be this fun? **HOW TO BOOK**: **It's essential that you book onto sessions via our website, using the link below**; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals. [https://joinrabble.com/locations/london/](https://joinrabble.com/locations/london/) Use the code **FREEPLAY** to get your first game free! *** We play every: * Monday in Finsbury Park (19:00 - 20:00) * Tuesday in Shoreditch Park (19:00 - 20:00) * Wednesdays in Elephant & Castle (19:00-20:00) * Saturday in Southwark Park (10:30 - 11:30) * Saturday in Finsbury Park (11:00 - 12:00) * Sunday in Clapham Common (12:00 - 13:00) We hope to see you playing soon!

We are ecstatic to announce the return of the ODSC AI Skills Accelerator to London! Join the local data science and AI community for an exciting, exclusive evening supported by Snowflake. Dive into a cutting-edge technical session led by a Snowflake expert and connect with your peers over complimentary food and drinks. Whether you're a seasoned professional or just starting your AI journey, this is the perfect place to learn, share, and network with fellow innovators. ## Featured Session **Speaker:** Teresa Nascimento, Senior Solutions Engineer at Snowflake [https://www.linkedin.com/in/teresanascimento/](https://www.linkedin.com/in/teresanascimento/) **Talk Title:** *Optimize your Agent’s GPA with Coding Agents* ``` In this talk, we will share how coding agents help developers build high quality agents faster. A key insight from building agents in production is that high quality agents operate with their goals, plans and actions aligned. We introduce the Agent Goal-Plan-Action or Agent GPA framework to capture this insight, which achieved state of the art benchmarks on TRAIL/GAIA with 95% error coverage and 86% error localization. This framework goes beyond examining the agent's final results to assessing the agent's process: Was the goal achieved efficiently? Did the plan make sense? Were the right tools used? Did the agent follow through? Without visibility into these steps, teams risk deploying agents that look reliable but create hidden costs in production. Inaccuracies can waste compute, inflate latency and lead to the wrong business decisions, all of which erode trust at scale. This approach to agent evaluation enables effective and fast optimization with coding agents. We will also show how to use coding agents to automate the process of measuring and improving an Agent's GPA by using agent optimization skills that take advantage of the GPA evaluation framework. By the end, attendees will be able to use coding agents and the GPA framework to identify common agent failures, improve their agent and make it ready for production. ``` Event Details * **Date:** Thursday, July 9th, 2026 * **Time:** 6:00 PM – 8:00 PM BST * **Location:** Snowflake HQ, 3 Crown Place, London EC2A 4EF, UK * **Networking:** Enjoy pizza and refreshments 🍕🥂 included with your attendance!

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.

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 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 .

Please get in touch with the organisers with any questions or concerns. As always, there will be free food and drinks, generously provided by our host, Man Group. **Main Talks** 1. Itunu Ijila - **What AI Engineers Can Teach Python Developers** Itunu builds AI pipelines. She has shipped agents, automation workflows, and intelligence reporting systems. And she has done most of it without writing a single serious line of Python. In this talk she shares what building production AI systems with tools like n8n taught her about good engineering. Pipeline design, observability, fallback logic, cost awareness, and why these principles matter regardless of the tools you use. She will also show how the architecture behind AI workflows maps directly to the agent patterns Python developers are building today with frameworks like PydanticAI. This is a talk about systems thinking and how good engineering has no syntax. 2. Astha Gupta - **Beyond the Demo: What Nobody Tells You About Shipping AI at Scale** Everyone wants to talk about the model. In enterprise AI delivery, the model is rarely the hard part. Over the last few years Astha has led the delivery of AI platforms for Fortune 500 clients across energy, agriculture, and chemicals. The hardest problems were never algorithmic. They were getting the data in the first place, making sense of it, showing progress before anyone loses faith, and balancing the pressure to move fast with the need to build something that actually scales. This talk covers the full arc of what enterprise AI delivery actually looks like in practice. Getting data from large organisations is often the longest part of the entire project, and the EDA that follows surfaces assumptions that break everything you planned. Showing features early, before the formal UAT four months later, is what keeps projects alive. And the pressure to deliver fast in sprints that have no room for a month long feature is where most technical debt quietly accumulates. The latest chapter of this story is coding agents. They make you faster than ever. But in enterprise codebases where scalability is not optional and understanding what you built is not a luxury, speed without comprehension compounds into something much harder to fix. This is not generic software engineering. The constraints are different, the stakes are higher, and the lessons are hard won. 3.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.
