**Tim Ruffles presents:** *Efficient Reconciliation and Flow Control for Anti-Entropy Protocols* [https://www.cs.cornell.edu/home/rvr/papers/flowgossip.pdf](https://www.cs.cornell.edu/home/rvr/papers/flowgossip.pdf) The ideas in this paper influenced [systems at Amazon](https://www.cs.cornell.edu/projects/ladis2008/materials/rvr.pdf?), and beyond, e.g. Cassandra, Ringpop from Uber (used in Temporal). **Abstract** The paper shows that anti-entropy protocols can process only a limited rate of updates, and proposes and evaluates a new state reconciliation mechanism as well as a flow control scheme for anti-entropy protocols. **The Speaker** Tim is an engineer at [poolside.ai](http://poolside.ai/), previously at Plaid & GitHub **Location**: Appold St and Worship St corner London EC2A 2AG https://maps.app.goo.gl/GmCdcBLBCLR2ifou7 The nearest tube/train station is Liverpool St The entrance is located at the street level.

Our acclaimed Wednesday workshop returns - we'll be looking at Lorca's classic drama exploring fate, passion, and societal expectations. A bride elopes with her former lover on her wedding day, triggering deadly consequences. Rich in poetic symbolism and folk traditions, the play confronts love’s destructive force and the inevitability of death and honor. We will be working towards A FULL PRODUCTION in April 2026..

Hello and welcome to our next **Data & AI Leaders** event. This session brings together Heads of Data, AI, and Analytics; senior technology and engineering leaders; Principal and Staff Data/ML Engineers; Platform and Capability Leads; and strategic decision-makers responsible for shaping data and AI strategy, governance, and value delivery within their organisations. Our meetups are friendly, thoughtful, and discussion-driven, designed to create a space where leaders can share real-world experience, reflect on complex challenges, and learn from peers who are building and scaling Data and AI capabilities in the real world. This session will include leadership talks, guided discussion, Q&A, and time for networking with fellow data and AI leaders. **We run:** • Bi-monthly in-person leadership meetups and roundtables in London • Bi-monthly online sessions for our wider leadership community Please keep an eye on our Meetup page for future events. Food and refreshments will be provided for in-person events where a host venue is supporting. We are delighted to host this security-focused meetup in London on the **22nd of January,** in partnership with [Incident.io](https://incident.io/). **Speakers and Sessions:** Speaker: [Dylan Ratcliffe,](https://www.linkedin.com/in/dylanratcliffe/) Founder at Overmind Session Title: How We Detected Toil among 36,000 Changes Description: How much precious engineering time are you spending on changes that don’t really need it? In this talk, we’ll reveal how we analysed nearly 37,000 infrastructure modifications to rigorously quantify "toil"; the work that slows teams down without adding real value. We’ll share the statistical techniques and practical models we developed to find the best opportunities for safe auto-approval, and show how you can use similar methods to identify (and eliminate) wasted effort in your own workflows. We’ll also discuss pitfalls, trade-offs, and how AI can take your approval process even further. Whether you’re a platform engineer or an SRE, you’ll learn how to free up your team to focus on what really matters while keeping your systems safe and reliable. Speaker: **[Rory Malcolm](https://www.linkedin.com/in/rory-m-m/)**, Product Engineer at Incident.io Session Title: My first year as an AI engineer Description: Join Rory, Product Engineer at Incident.io, as he walks through everything the team learned in their first year building an AI capability. This session focuses on how they scaled both technically and socially, growing from early work into an engineering team able to make meaningful progress against real AI goals. Expect practical insight into team growth, collaboration, and what actually enabled progress. **Agenda (GMT / UK):** 18:00 — Welcome and refreshments 18:30 — Introduction — Ethan Sumner 18:35 — Speaker 1 19:10 — Break 19:20 — Speaker 2 19:55 — Close and networking **We are always keen to hear from:** • Speakers — leadership case studies, transformation journeys and strategic insights • Hosts — organisations able to support executive-style roundtables and meetups • Sponsors — support with venue access, refreshments, recording or accessibility If you would like to speak, sponsor, or host a future session, please get in touch with **[Ethan Sumner](https://www.linkedin.com/in/ethansumner404/)** via LinkedIn.

You can expect a friendly introduction to the sport, but in all honesty you will dive in at the deep end to learn UWR. Please bring swimwear and an open mind and expectation to have fun. We can lend an UWR hat, snorkle, mask and fins. Although if you have them already it is better to bring your own. Expect to swim, dive to 4m depth, hold your breath longer than you thought you could, be involved in drills and games. It is full contact and you will be wrestling other players to take the ball and pass to your team or score a goal. Please get on touch with questions or intent to attend prior to session so that we can support with kit etc.

The first rule of WRITE CLUB is that you do not talk *during* WRITE CLUB. This very simple meetup is based on the premise that public and peer accountability enables more productive writing than sitting at home and getting distracted by the fridge. We will write/read for an hour in silence. (I will be writing thought experiments for my other meetup group: [THOUGHT EXPERIMENTS IN PUBS](https://www.meetup.com/thought-experiments-in-pubs)) If you'd like to hang out afterwards, or if you prefer just to hang out, I have another event immediately afterwards in the same place :-) You can find that here: [HANGING OUT AT THE SOUTHBANK](https://www.meetup.com/experimentsin/events/312667892) We'll make use of the fantastic indoor public spaces on London's South Bank (The Southbank Centre, The BFI Cafe, The National Theatre Cafe, etc) to spend time in the company of other people. There are plenty of places to buy refreshments, but you can also bring your own if you prefer. This first event will take place in the foyer of The Southbank Centre. You can find us by looking out for a big red flag with THE SUNRISE CLUB emblazoned on it (though this clearly isn't THE SUNRISE CLUB! If you want to find out about that, you can do so [here](https://www.meetup.com/the-sunrise-club/).) Looking forward to meeting and writing with you :-) Bonny

Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA
