🎉 Come along to the London Scala Talks for a deep dive into functional architecture! 🎉 In this event you'll hear from David Lebl and Przemysław Pokrywka. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Przemysław Pokrywka: Ports and Adapters for People on Tight Schedules 7:20pm - 🍕 Intermission: Join us for some free food and drinks!

Terms such as architecture astronautics and the ivory tower stereotype highlight the perceived disconnect between many architects and the realities of day-to-day code maintenance. Too often, architectural patterns are applied with insufficient understanding, leading to cargo-cult adoption and increased waste in the software development process. When applied in the right context, however, certain architectural approaches can be powerful enablers. In this talk, I would like to share the story of a serverless application in which elements of the Ports and Adapters architecture made a tangible, positive difference. ⭐ Przemysław Pokrywka ⭐ Husband, dad, grandad, software engineer. Functional Scala enthusiast with imperative OOP Java background. Fan of the command line. **🗣️ David Lebl: Complexity is a Sin, But Hexagons Forgive** A visual journey from spaghetti to sanity. This talk traces how cognitive load accumulates in unconstrained codebases, how domain-driven design and bounded contexts restore order, and how hexagonal architecture provides a practical, forgiving structure for real-world systems — all laid out on a single zoomable canvas where every example links back to the bigger picture. ⭐ David Lebl ⭐ David is a software developer with a CS background and 5 years of Scala and FP experience. He leads a small team, occasionally survives his own accidental complexity, and is here to share what he learned the hard way. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

We’d like to invite you to the final Wytchery, before we take a break for the summer. This one will therefore be a bit special and we will be combining the things that we’ve learned over the past year into a big summer ritual and celebration. This session is intended for those who have previously attended the Wytchery. Don't worry if you haven't, as you can always join us in September. We started the Wytchery in June 2022 hoping that we could give people an experience of what it might be like to work in a group and you have all made it so much more magical than we could ever have expected. Thank you so much for coming with us, participating, contributing and creating the wonderful experience that is the Wytchery. **We are asking for a fee of £10 (+booking fee) to cover Treadwell’s overheads as well as the cost of any supplies. Please arrive at least 15 minutes early as we start promptly at 7pm.** The Wytchery is an inclusive programme of workshops for solitary witches with little or no experience working with a group. Witches can drop in and out and will gain hands-on experience raising power, working magic, trance, spells, talismans and magical tools and using these in group work. Expect to get involved –moving, making or meditating. Expect to meet people, to learn and to contribute. You will walk away with new skills – and often with something for your own practice. Note that we are not making money from the Wytchery, we hope for it to be a purely social endeavour. Our workshops are aimed at witches who have not had much, if any, experience of working within a coven or a magical working group – or even working on your own, if you are new to the craft. If you have some experience but would like to hone your skills, you would also be most welcome to join us. We find we learn new things all the time, even after years of magical practice.

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? **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.

After the rehearsal we go to a nearby pub for social drinks where everyone is welcome :) What do you need? 1. Ideally a cotton shirt: to protect your neck and shoulders, the more durable the shirt/top the better. We do not recommend any thin items of clothing! 2. Jeans: allowing you to move freely without breaking. 3. Mask: We still require the use of a mask as you will be very close to your fellow Castellers - basically you will be hugging people! The rest of the equipment is on us!

Our regular members won't be filling in the Meet Up to say they are going 🙂 So don't be put off if you see only a handful have said they are going. A minimum of 25 on the day is normal. What the Meet Up may show is how many new people like yourself are going.

Who wants to come see an artist attracting some buzz on various BBC Radio channels (6music and the more mainstream one)? It's also on a Saturday so no worrying about getting up the next morning (yay!) Some stolen artist blurb: "Gretel Hänlyn is a 20 year old singer, songwriter & guitarist from West London. Having been raised on a diet of Nick Cave it was no surprise that Gretel picked up a guitar & started writing her own gothic stories and songs at age 11. As she grew as a musician, started going to gigs & fell in love with Tim Buckley, Nirvana and then Wolf Alice, her songwriting began to morph into what it is today; a mix of hi-fi grunge, goth-pop and alt/indie ballads." Currently promoting her debut album 'Squish' (standout track Darkness Be My Friend IMO) you can check her out at: [Spotify](https://open.spotify.com/artist/39HYn2OCDJFkUauHXqwBsG?si=U5KCQqrzR0i8ok0sQsyB5A) [Youtube](https://www.youtube.com/@grrretel) Still remaining tickets (£17) at [Ticketweb](https://www.ticketweb.uk/event/gretel-map-studio-cafe-tickets/14948053?REFERRAL_ID=tmfeed&duplicate=1&googleaid=573cd54f-5b3a-4456-9e8f-d67c7ccd17d7), get 'em while there's some left!

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
