Cryptography

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

**PLEASE NOTE WE WILL BE CLOSING OUR MEETUP GROUP IN JUNE 2025 due to spiralling costs of membership.** **YOU CAN FIND US HERE INSTEAD:** \* FACEBOOK: [www.facebook.com/groups/crystalpalaceboardgamesbeyond/](www.facebook.com/groups/crystalpalaceboardgamesbeyond/) \* WEBSITE: [https://sites.google.com/view/boardgamesandbeyond/home](https://sites.google.com/view/boardgamesandbeyond/home) Join us for an epic game night filled with social fun and exciting tabletop games at Crystal Palace Board Gamers meet-up! Whether you're a fan of strategy, dice, card, or board games, there will be plenty of options for everyone to enjoy. This is a fantastic opportunity to make new friends, connect with fellow gamers, and immerse yourself in a night full of fun times and laughter. So grab your favorite game and come join us for an unforgettable gaming experience. Let the games begin! Feel free to join us by hitting that attend button below. **What to expect:** * We meet at the Anerley Arms (next to Anerley train station) from 7pm (there is food available at the bar) * If you do not have a game setup, you can arrive at any time. If you do have a game to set up we recommend getting there earlier. * It is a relaxed atmosphere, where we generally prioritize company over fierce competition. * Please bring along any games you think we might enjoy, or you can play from the games that others bring. * We split into a few groups based on people's game preferences and numbers, and usually have plenty of time to try a few games over the course of the evening. * The event hosts are regular attendees but might not make it to every event - if you can't spot us, then just approach the folks sitting at tables surrounded by board games (usually on left as you come in the door). We're a friendly bunch and will be more than happy to welcome you. (Please update your RSVP if it turns out you'll be unable to attend, to free up your space for others who may otherwise miss out!)

# Learn how to use open-source harnesses like OpenCode & Pi w/ your own LLM and with it, build a real-world application **Registration to this event is only valid through the Luma platform:** [https://luma.com/11txn8gq](https://luma.com/11txn8gq?utm_source=meetup-dot-com) ​Hello code campers! ​Since everyone is talking about using harnesses such as **Anthropic Claude** or **OpenAI Codex**, meaning, everyone is probably tired of hearing about them, we've decided to go in a different direction and explore other, lesser known things such as, [OpenCode](https://opencode.ai/?utm_source=luma) and [Pi DOT Dev](https://pi.dev/?utm_source=luma). Come and join us and learn how to work with a wide range of open-source large language models (**LLMs**) such as **DeepSeek V4**, **Gemma**, **Kimi K2**, and **GLM** across various local-first environments. This comprehensive workshop is designed to teach you what is a code harness, how many types of them there are out there (you might be familiar with **Claude Code** or **Codex** or **CoPilot** but there are others and since the big-tech companies are moving to token-based usage, why not run your own solution locally). Also, we'll explore how to go about having effective agentic coding workflows while benchmarking model performance and hardware requirements. ​We will go through the setup process, focusing on how to install the desired LLM runner like Ollama or LMstudio locally. ​This will be our **7th** event in our series of **local-first, open-source** AI events; therefore, we will try to focus on building a setup that doesn't depend on Big Tech but on smaller open-source tech instead. ​This workshop is open to all levels, from beginners to experts. ​Bring your laptop (make sure it's fully charged as local LLMs tend to be power-hungry), and don't forget to bring your coding gear (hoodie). ​This workshop will be most likely accompanied by a guest speaker (TBD). *** ## ​Prerequisite ​Prerequisite: a local Ollama, LMStudio installation or equivalent (but if you don't have any of that, don't worry, come a bit early and we will help you). ​If you want to take a quick look at the slides from the previous events fell free to do so: [​https://andysign.github.io/ai-london-01/](%E2%80%8Bhttps://andysign.github.io/ai-london-01/) (Ollama); [​https://andysign.github.io/ai-london-02/](%E2%80%8Bhttps://andysign.github.io/ai-london-02/) (LangFlow, not really related but still) [​https://andysign.github.io/ai-london-03/](%E2%80%8Bhttps://andysign.github.io/ai-london-03/) (private RAG w/ Anything LLM) [​https://andysign.github.io/ai-london-04/](%E2%80%8Bhttps://andysign.github.io/ai-london-04/) (AI-native browsers) [​https://andysign.github.io/ai-london-05/](%E2%80%8Bhttps://andysign.github.io/ai-london-05/) (OpenClaw basics) [​https://andysign.github.io/ai-london-06/](%E2%80%8Bhttps://andysign.github.io/ai-london-06/) (OpenClaw advanced) *** ## ​Agenda for the evening (Subject to change) ​**18:00 - 18:30 Arrival and networking** Mingle with fellow developers over refreshments. ​**18:30 - 18:45 Introductions** Intro and a bit of audience engagement. ​**18:45 - 19:40 Workshop** ​Hands-on technical workshop (if you are non-technical it's OK, tag along). ​**20:30 - 20:45 Guest Speaker** ​**20:30 - 21:00 Networking** ​**21:00 - Closing remarks and follow-up** ​ **END:** Carry on the fun at a nearby pub around the corner. *** ## Event Venue We'd like to extend a heartfelt thank you to **Encode Club**.

Guest then circulates to find a match to their lock or key. The aim is to meet as many as people as possible in one night, and have fun along the way.** **These events allow for you to be as forward as you like work the room like the social and you are or stand back and let people come to you! It works great both ways.** **When and if you find your match you then return to one of our friendly and helpful hosts who will arrange for you to be given another lock or key.** **We call this a match, through a relationship isn’t compulsory! You’ve met someone new and now this is your chance to win one of our great prizes that are drawn throughout the evening. Return to the organizer’s desk (with your match) and present us with your open lock and key. Our host will give you both a new lock and key and you’ll both pick up free raffle ticket to win some great prizes later on in the evening but also the chance to find your ideal match! You’re free to continue meeting new people or chatting to your latest match.** **If the key doesn’t open the lock, not to worry move onto the next person, you will meet plenty of people in one night, remember it is a party.** **The lock and key icebreaker part of the evening lasts around two hours. After the event you will have met loads of new people so most people stay on and continue mingling. 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. Dirty Martini Bar the perfect place to relax and recharge by day, then party through the night.** **Please Note: when the Lock & Key Party end at 10.00pm or if you decide to leave before, then please hand over all your Locks & Keys to your organiser.** **Dress Code:** **Smart Elegant or Smart Casual.** **Directions:** **The nearest station is Monument Train Station** **Important information** **19.00-Doors open (please arrive on time)** **19.30-Lock and Key icebreaker begins** **21.30-Prize draw**

**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.

Over a billion documents processed. Millions of Veterans impacted. Hundreds of thousands of employee hours saved. Faster decisions. Greater accuracy. More benefits in the hands of our disabled Veterans. We created Smart Search, the world’s largest consumer of Amazon Textract, right when GenAI began reshaping what’s possible. Since then, we’ve built a suite of AI‑driven solutions that transform this data into real, measurable outcomes—accelerating benefits decisions for our Nation’s Veterans. Join us for a focused conversation on how an outcome‑driven approach to AI is helping us boost accuracy, streamline workflows, and deliver faster results for those who have served. This is a follow up to the AWS re:Invent 2023 "Intelligent Document Processing with Gen AI for Public Sector" presentation.

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.
