Decentralized Systems & Applications

Join us for an exciting evening hosted once again by **Apple at their Battersea Power Station campus**! Enjoy informative talks and make the most of the chance to meet fellow Swift developers. We can’t wait to see you there! Note we’re starting **30 mins earlier** than usual. Space is limited, so RSVP early to secure your spot. If your plans change so you can’t make it, update your RSVP so others can attend. **Talks:** **Darryl Bayliss** — *"Building Apps for Multiple Apple Platforms*" Have you ever wondered how an app works across different Apple platforms and what the setup could look like for your own ideas? This is the talk for you. Learn how to work within an Xcode project building apps for Apple's variety of platforms using the power of Swift and SwiftUI. Along the way you'll understand the benefits of multiplatform development, best practices, and the pitfalls to avoid! Aimed at intermediate engineers and above with an understanding of Swift / SwiftUI APIs, Xcode project configuration, and multiple Apple Platforms. **Richard Das** — *"Software on Demand in the Age of AI"* With agentic coding in Xcode 26.3, software is increasingly on demand. When code can be generated in seconds, the question shifts from “can we build it?” to “what standards do we apply?” This talk explores how to work with AI thoughtfully, focusing on architecture, judgement and quality, and introduces themes from Richard's upcoming book on development in the age of AI. **Schedule:** **6:00 PM** Arrival and check-in at Apple reception **6:30 PM** Presentations start **8:00 PM** Community networking **9:00 PM** Continue the conversation at [Battersea Brewery](https://maps.apple.com/?address=12%E2%80%9314%20Arches%20Lane,%20London,%20SW11%208AB,%20England&auid=17789545786206344102&ll=51.482866,-0.146846&lsp=9902&q=Battersea%20Brewery) (to be confirmed) **Details:** **Full names required:** Ensure your Meetup profile has your full name or send it to us in a private message at least 48 hours before the event. **No photos or videos:** Thank you for respecting Apple’s policy. **Check-in:** Go to Apple reception on the ground floor (see map).

Schedule 18:00-18:30 Welcome, snacks, drinks and networking 18:30-19:00 **From Service to Line Number: Getting Started with Continuous Profiling** by Christian Simon, Principal Engineer at Grafana Logs, metrics, and traces tell you which service is slow or expensive. Profiles tell you which code path - down to the line number. With profiling now part of OpenTelemetry, and the eBPF profiler requiring zero instrumentation, there's never been a better time to add this missing piece to your observability stack. 1\. Value of Continuous Profiling 2\. How do you set up continuous profiling \(Pyroscope \+ OTel eBPF profiler\) 3\. Deriving insights from Profiles using Grafana Assistant 4\. Demo 19:00-19:40 **My Cool Grafana Dashboard Show and Tell - Lightning Talks** **Lightning talks:** **1\. What if Your Career Had Metrics?** **Roxana Turc, Software Engineer at BNY**, will show how she used Grafana to build a **career dashboard—tracking learning, work, and growth**, and why seeing her progress this way changed how she thinks about development. **2\. Using Grafana for Visualising IoT Air Quality Sensor Data** by John Sinha, Lead Technical Business Analyst IoT air quality sensors produce noisy, high-resolution time series data, but how you visualise it determines what you actually see. This lightning talk walks through a Grafana dashboard designed to **present environmental data clearly, covering time and value scaling choices, linear vs. log views, and practical denoising techniques.** See how small visualisation decisions can dramatically change the story your sensor data tells. 3. **How I discovered pigeons sabotaging my project with Kafka and Grafana** \- by Hugh Evans\, Developer Advocate at Aiven Learn how how a lightweight Kafka + Grafana observability stack helped Hugh **catch his avian adversaries** and iterate on a hobby project **without enterprise-scale complexity or costs**.

We are holding accessible and confidential Systemic & Family Constellations group workshop. Systemic constellations are an embodied and experiential method for the respectful exploration of difficulties across multiple areas of life. Attendees up to 16. One of three facilitators will facilitate two to three issues. Fee: Flat fee of £45 for both issue holders and representatives payable prior to the event. More information on our website https://cityconstellations.com/ or upon request londoncityconstellations@gmail.com

Please note - make sure you book a space if you are coming to the event as we have a certain amount of tickets available. Have you ever been to a public speaking class where they expect to go up and speak for 2 minutes with no prior experience ? I think this is too hard for many people and just overwhelms the nervous system. This workshop is designed for people who want a gradual and easier approach. We’ll start with some low-pressure warm-up games in pairs and small groups to help everyone relax and loosen up. We’ll move into groups of four, where you’ll speak in front of three people and answer a couple of questions. After that, we’ll move into groups of six and do another round or two. Finally, there will be an opportunity to speak in front of the whole group. But please don’t worry if that sounds intimidating—you will never be pushed or forced to do anything you’re not comfortable with. Even coming up and saying your name can be a victory! You are under no pressure to do anything, there are no minimum durations in speeches, all exercises are voluntary and no one will ever be put on the spot We'll be in studio 12, at the theatre deli which is 107 Leadenhall street, closest stations are bank and monument. I hope to see you there, if youre still worried feel free to send me a message and hopefully I can put your mind at ease 
Take care 
James.

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.
