Cryptography

**This event is supported by The Royal Institute of Philosophy’s [Local Partners Programme](https://royalinstitutephilosophy.org/news/fund-your-event/).** **N.B. this meeting will be held in person in the Prince of Wales pub near Covent Garden. There is also an online session held on Thursday if you are not in London or are not able to attend in-person.** Halfway through our thematic 'Quest' year, we are going back farther than we've ever been to one of the oldest surviving stories, one of the foundations of Western, and now global literature. Homer's Odyssey is the tale of Odysseus' homecoming to Ithaca after defeating the Trojans - his temptations, battles, failures and victories, all interwoven with his wife Penelope's resolve to fend off suitors, and his son Telemachus' search for news of his father. Expect discussions of duty, justice, temptation and different forms of power and leadership. The meeting starts at 7pm with drink breaks at 8 and 9. The discussion will end around 10pm, but leave whenever you need to. Here's the blurb from goodreads.com: If the *Iliad* is the world's greatest war epic, then the *Odyssey* is literature's grandest evocation of everyman's journey though life. Odysseus' reliance on his wit and wiliness for survival in his encounters with divine and natural forces, during his ten-year voyage home to Ithaca after the Trojan War, is at once a timeless human story and an individual test of moral endurance.

🎉 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! Vegan and vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ David Lebl: Complexity is a Sin, But Hexagons Forgive 8:30pm - 🥤 Socialising: Grab a drink and let's discuss the talks. 9:00pm - 🍻 Join us in a pub to discuss the talks! 🌐 **This event will not have a live stream** We hope to see you there in person. **🗣️ Przemysław Pokrywka: Ports and Adapters for People on Tight Schedules** Focus on software architecture is not always associated with pragmatism in common perception. 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 have a lot of regulars who have been enjoying our group for years. If you sign up and can not make it, you must drop out by 11pm Tuesday night. If you drop out later you will be taken off any games you sign up to play the next week. If you cannot make it but are on the waitlistist, please drop out before 12pm Wednesday. If you are put through to play and dont show up, the same rule applies. We are strict on these rules as we like the games as even as possible, plus someone else could have made it off the wait list! We usually play between the skate park and band stand. Set up: Clapham is set us as two pitches, each with a 10 aside game.

Everyone must go in 2\. No slide tackles\. 1 warning only\. This is due to it being casual and varied in skill level\. 3\. Be inclusive\. Pass to everyone and be positive\. Anyone who says anything rude to another player will be warned once and then asked to leave\. We recommend you wear plastic studs(metal are not allowed) or AstroTurf boots. Shin pads are optional but most people don't wear them. We have colour bibs so please wear what you want in those regards.

This is a live session at The Mitre in Greenwich. The purpose of this meeting is to provide and receive critique on submitted extracts of members' creative writing, whether they're working on a novel, screenplay, poetry, a memoir or short story, etc. We share our extracts via email ahead of the meeting to give us all a chance to read the work in our own time and reflect upon it so as to be able to provide useful critique. If you want to submit an extract mail me at gpatrick66@hotmail.com to book a slot. If you are new to the group we ask that you participate in at least two of the Wednesday critiquing sessions before you submit work for review so that you get to know us and have a good understanding of how we operate. This will help you to get the most from a critique of your own work. Extracts should be approx 3,000 words and the full document (extract plus blurbs, questions etc) should not exceed 3,500 words in total. Extracts must be mailed to me (gpatrick66@hotmail.com) at the latest by 9pm on the Saturday before the session so that I can share your work with the rest of the group. We have a limit of 4 extracts per session to give adequate time to review work properly. Feel free to give guidance on any specific areas on which you would like feedback. E.g. Plot, pacing, structure or character development etc. (If you have not received the extracts by the Sunday before the session, mail me.) The group is friendly and relaxed, so please don't feel nervous about sharing your work! We will normally review extracts according to the order in which they are sent to me but if you need a particular slot let me know when you submit your extract and we will try to accommodate that. Please note that all phones MUST be switched to silent mode for the duration of the meeting.

Unless otherwise announced this is an in-person social gathering for Smalltalkers to get together and talk about Smalltalk (the Programming Language!). Everyone is welcome from the grizzled and experienced to the merely curious.

Connecting people into Philosophy. All welcome. No previous philosophical experience needed. **What it is** Philosophy in the Park is a fun and friendly space for people to come together and have discussions that get deep. It’s a safe space where active creative thinking is encouraged and enjoyed, and where everyone can explore abstract concepts in a way that combines both sincerity and playfulness. Where the most important question is always - what do you think? **What is Philosophy?** Philosophy is about analysing concepts. It's thinking about thinking. It's not about empiricism or the physical world (eg Science and statistics). It's about abstractions, concepts and ideas (eg Identity, Morality, Mind and Truth). **How Philosophy in the Park Works** * Each hour begins with a group vote on which questions to discuss. You can vote for more than one question if you'd like. * We then break out into groups, each focusing on one of the chosen questions. The question is just a starting point and it's cool if you go on tangents and end up talking about different things. You're welcome to join in and participate or if you'd prefer to sit back and enjoy the conversation, that’s also welcome. * After an hour we regroup, take a quick break and then repeat all over again. So across the 3 hours, we’ll break out 3 times. **Where it is** We meet at Baroness Burdett Coutts Drinking Fountain in Victoria Park (East Park). It is marked down as "13" on the official maps found in the park. Please feel free to bring snacks and drinks with you if you want. After the event finishes most people stay and hang out. There’s a local supermarket to get drinks and snacks, or bring your own. You are very welcome to join us. **Guidelines** In order to make the conversations as fun, interesting and productive as possible please follow these simple guidelines: 1. Keep it Philosophical (No Science, no History, no Sociology, no Evolutionary Psychology, no contestable facts, personal anecdotes etc). 2. Think for Yourself (No phones, no looking up definitions, no name dropping Philosophers / books you've read). 3. Tangents are Cool (Don't worry too much if the subject drifts and you don't answer the question). 4. Keep it Succinct (Like this). 5. Be Excellent to Each Other (But of course). Please remember: It's not about debating and trying to win - it's about listening to people and working collaboratively to increase our collective understanding. **Community** We have a WhatsApp group if you'd like to continue these conversations between meetings.

But don’t go rushing off – most people have met lots of people by then so it’s time to get down to the business of flirting and swapping numbers! You can stay in the venue until it closes and from experience most people do. You are welcome to stay on in the venue as they often stay open late. Alternatively some people will move on and dance the night away with their new friends. The choice is yours.** **Venue:** **Dirty Martini Bar is eclectic, eccentric escape from the daily grind.

Join us on June 11th from **6:00pm** for a Data Streaming meetup hosted by **Moniepoint!** **PLEASE bring your PHOTO ID and REGISTER with your First and Last Name. For security purpose** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:15pm: Tom Scott, CEO, Streambased * 7:15pm - 8:00pm: *Abraham Imohiosen,* Engineering Manager * 8:00pm - 8:30pm: Q&A Networking. 💡**Speaker One:** Tom Scott, CEO, Streambased **Title of Talk:** Infinite Kafka? Rethinking Retention with Iceberg **Abstract:** Apache Kafka is designed for high-throughput, low-latency event streaming, not cost-efficient long-term storage. Yet we constantly see cases like event sourcing, audit/compliance, and large-scale reprocessing forcing that pattern onto it. As retention increases, costs grow linearly to support edge cases, one-time runs, and “checkbox” use cases. Can Iceberg help here? In this talk, Tom explores a hybrid architecture that separates hot and cold data while preserving Kafka’s log semantics. Using a combination of Kafka and Apache Iceberg, he demonstrates how to extend Kafka into low-cost object storage, enabling effectively unlimited retention without sacrificing performance or access patterns. The result is a unified log that supports both real-time processing and long-term replay, removing the traditional trade-off between cost and capability in Kafka-based systems. **Bio:** Long-time enthusiast of Kafka and all things data integration, Tom has more than 15 years of experience in innovative and efficient ways to store, query, and move data. Tom is currently CEO at Streambased, a company focused on unifying operational and analytical data estates into a single, consistent, and efficient data layer. 💡**Speaker Two:** Abraham Imohiosen, Engineering Manager, Fraud Prevention Tools. **Title of Talk:** From CDC to Decision: Kafka as the Fraud Detection Pipeline's Connective Tissue **Abstract:** Fraud detection isn't one system — it's a system of moving parts (databases, feature stores, rule engines, ML models, case management tools) that all need to agree on what just happened, in milliseconds. Kafka sits in the middle of it, and treating it as "just the message bus" leaves a lot of value on the table. In this talk, I'll walk through three jobs Kafka does inside Moniepoint's fraud detection pipeline: moving events between services, powering real-time aggregations and windowed features, and acting as a CDC source that turns database changes into the canonical stream feeding a final aggregate store, as well as routing evaluated events into the case management system for final decisioning. **Bio:** *Abraham Imohiosen is an Engineering Manager at Moniepoint, where he leads the Fraud Prevention team in building case management systems and machine-learning detection models that protect millions of customers and billions in transaction volume. He has over 10 years of experience across fintech and cloud-based architectures, having previously led the delivery of Monieworld Transfers and a savings product. Abraham holds an M.Sc. in Robotic Systems Engineering from RWTH Aachen University.* \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

A regular meetup for those committed to practising and improving their Arabic. It is designed for those who know the very basics and want a structured opportunity to practise reading, listening, speaking, and building confidence. If you're still learning the very basics but want some motivation to keep going, you're very welcome to join. Note: This is a practice group facilitated by a native speaker - not a formal teacher or taught class, and not a Quran teaching session. 📚 SESSION FORMAT: ⏱️ 30 mins Intro & Social: We'll go around and introduce ourselves in Arabic. Feel free to prepare 2-3 sentences beforehand if you don't like being put on the spot! 🗣️ 60 mins Structured Practice: A focused session practising together with guidance : ◾ Taking turns reading passages aloud ◾ Listening to excerpts from an audiobook ◾ Working together to translate and understand the text 💬 Continued Socialising: Feel free to stick around afterwards for more informal chat and connection. ✊ Note: Active Muslims is equally about focusing on the actual activity, in this case, it is a practice session requiring mental engagement and active participation (and not just a social), therefore it is advised to approach and attend these events with that mindset, intention and purpose. 📍 LOCATION: Barbican ⌚ MEET: By the cafe G Level (Benugo) ⏱️ TIME: Meet from **11:00am** for intros and socialising. The practice session starts promptly at **11:30am** insha'Allah. 🎒 What to bring: 📚 Any Arabic texts you would like to read 🎧 Headphones (optional, if you prefer listening privately) ➖➖➖➖➖➖➖➖➖➖➖➖ If you can no longer attend, please update your RSVP to free up your spot for someone on the waiting list. ➖➖➖➖➖➖➖➖➖➖➖➖ 🌐 **[@Active.Muslims](https://www.instagram.com/active.muslims)** *(Follow for latest events updates)*

**The event has been canceled.** *Note: this is a demonstration event only, you **will not** shoot you own images. However, if you bring your camera we can test it for compatibility with the studio lights.* Bondage elements can add an extra layer of emotion and artistry to your images. Sample images on the internet are however dominated by BDSM style shots that are often sexualized and emphasize the model being in distress. In this demonstration Rachel and I show ways to use bondage elements in an artistic way. We explore the types of accessories that work best in artistic images and the best way to photograph them. Our model is Rachel Adams, an internationally known fetish model with many years of experience in this genre.

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.
