Hi folks! Welcome to our July Cloud Native London meetup! Join us to hear from our two speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube or LinkedIn! 6:00 Pizza and drinks 6:30 Welcome 6:45 Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for Safety (Hossein Kakavand, Luther Systems) 7:15 Putting Open GitOps to the test (Steve Fenton, Octopus Deploy) 7:45 Wrap up See you there! Cheryl (@oicheryl) **Putting Open GitOps to the test (Steve Fenton, Octopus Deploy)** The Open GitOps principles sound plausible, but the world is full of surprising realities. Join Steve Fenton and explore the GitOps research to see whether GitOps delivers on its promises, based on an analysis of over 600 perspectives from roles like DevOps engineers, developers, platform engineers, and cloud infrastructure engineers. *Steve Fenton researches the socio-technical systems behind software delivery; how organizations, people, and technology actually work together (or don’t). At Octopus Deploy, he explores GitOps, Platform Engineering, Continuous Delivery, and compliance through a lens shaped by punk history, psychology, and the kind of genre fiction that asks uncomfortable questions about systems and society.* *He’s an eight-time Microsoft MVP (DevOps), a DORA Community Guide, a CD Foundation Governing Board member, and a contributor to the CNCF Platform Engineering Community Group. He’s written books on TypeScript, Octopus Deploy, and Web Operations Monitoring, and occasionally writes horror fiction.* *https://www.linkedin.com/in/stevefenton/* *https://mastodon.social/@stevefenton* *https://bsky.app/profile/stevefenton.co.uk* **Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for Safety (Hossein Kakavand, Luther Systems)** The more freedom we give an autonomous agent, the more it drifts into hallucinations or policy violations, yet clamping it down with prompts kills the reasoning we want. Think Brownian Motion versus a Brownian Bridge: a random walk wanders anywhere, but pin it at fixed points and it moves freely between them while always landing where it must. Deterministic checkpoints are those pins. InsideOut applies this to infrastructure. It works with the user to shape a feature set, stack, config, Terraform and cost estimates, then deploys and manages the infrastructure in real time for monitoring, alerts and changes. Each stage must produce a structured artifact validated against fixed rules, and if a check fails only that stage repeats, catching errors before they propagate. High-stakes actions stay locked down by design: the agent can request a deploy by presenting a button, but never holds the cloud keys itself. The result is an agent that is more productive precisely because it is safely unconstrained. *Hossein Kakavand holds a Ph.D. from Stanford University. He has been with several start up in AI, ML and Distributed Systems, with IPOs on NASDAQ and LSE. He is currently a Co-Founder of Luther Systems focused on solving the Enterprise Operations problem at scale. @HosseinKavavand* ***Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.***

Walk length 6miles/10km approx. Linear. A chance to explore a section of the Wandle Trail from South Wimbledon to Carshalton. The Wandle trail is a walking route following the river Wandle from Wandsworth to Croydon. It was heavily industrialised but is now largely a nature trail with a number of nature reserves as well as some more urban sections. Along the trail is the historic Abbey Mills. We can at the end visit a pub at Carshalton 'The Hope' which has a great selection of real ale and craft beers it also has a beer festival on this day (www.hopecarshalton.co.uk) Carshalton has various transport routes back into central London. Meeting and Transport Meet outside South Wimbledon tube station from 6.15pm the walk to start at 6.30pm. This is a FREE walk My phone number is Colin 07709 305681. Walking is a great way to keep fit and generally very safe; however it does contain an element of risk. Before going on any of these walks you need to be reasonably fit and be prepared to be responsible for your own safety. You should wear appropriate clothing such as proper walking shoes, warm and wet weather clothing and carry sufficient food and water.

Hot Bi Beverages! The Bi Coffee group (a separate group) meets at 3–6.30pm on the first Saturday of every month. The old Leon venue is permanently closed, so the group now meets in a Caffè Nero near Tottenham Court Road/Shaftesbury Avenue. **The venue**: Caffè Nero, the Central Saint Giles one; at the bottom (south end) of Earnshaw Street, at the corner with Shaftesbury Avenue (a big junction); round the corner from Tottenham Court Road Station. **Address**: 1a St. Giles High St, London WC2H 8AG Vicki is running Bi Coffee each month, come and go as you please. Find us by looking for our little purple unicorn and sign. Respect each other. Newcomers and quiet people are most welcome. There are regulars from outside our group (but in the general London bi community) so even if there's no-one else listed from here you'll be in a friendly and safe group. But do please note this is a separate group from our meetup group and for most reliable updates check out the [facebook page](https://www.facebook.com/groups/bicoffeelondon/). Its run enthusiastically by upstanding bi community member(s) and heartily recommended if more relaxed and quiet hanging out in a café is more your thing. 🟣 Accessibility: The cafe is ground floor and claims disabled toilet and access, baby changing facilities, wifi, and air conditioning (only one toilet though, which can occasionally mean a longer queue for that than for service). The cafe is opposite Tottenham Court Road bus stop S (busses 14, 176). It is on the junction so taxis will need to stop outside it. From Tottenham Court Road station head south on Charing Cross Road, take the left on Denmark Street, and then keep straight. It's under the large bright yellow Lego building. 🟣 More Info: Facebook group: [facebook.com/bicoffeelondon/](https://www.facebook.com/groups/bicoffeelondon/) Old Bi Coffee website (ignore the outdated location,map): [bi.tocotox.org/bicoffeelondon/](http://bi.tocotox.org/bicoffeelondon/) Venue: [website](https://caffenero.com/uk/store/central-st-giles-654/) / tel:[02072407412](tel:02072407412).

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
