**Can R tame the LLM chaos? Let's find out. 🤖** Two talks. Two live demos. One evening that might change how you think about LLMs in R. Refreshments and networking from 18h00. **Agenda** \~\~\~\~\~\~\~\~\~\~\~\~ \* 16h30 – 16h45 \| Welcome and News \- Handre Williams & Luis de Sousa \* 16h45 – 17h20 \| Handre Williams: **R as the orchestration + statistical validation layer for LLMs** LLMs are powerful but unreliable. R is rigorous but underestimated. This talk explores what happens when you combine the two — using R as the orchestration backbone and statistical validation layer for LLM workflows. Handre will show practical patterns for calling, chaining, and stress-testing LLMs from R, and how classical statistical tools can keep your models honest in production. Includes a live demo. \* 17h20 – 17h55 \| Luis de Sousa: **RAG (Retrieval-Augmented Generation) in R** LLMs hallucinate. The fix? Give them better memory. This talk dives into Retrieval-Augmented Generation (RAG) in R — combining DuckDB's vector search capabilities with R's data ecosystem to ground LLMs in domain-specific knowledge. Luis will show how to build a RAG pipeline from scratch, turning your own data into a knowledge base that makes LLMs actually useful in practice. Includes a live demo. \* 17h55 – 18h00 \| Wrap up\, questions & close \* 18h00 \| Refreshments & networking — continue the conversation in person **Details** \~\~\~\~\~\~\~\~\~\~\~\~ When: 14 April 2026 @ 16h30 to 18h00 (GMT+2) Where: Microsoft Campus in Bryanston, South Africa Location: https://goo.gl/maps/4ffcC3N6T7S2 Keen to speak at a future event?

Interested? Contact Preston Moore k.preston.moore@gmail.com 614-300-5989 ———————————— Engaging in men’s work is the new way to forge friendships while being open-minded to personal growth. Many men experience healthier relationships, personally and professionally, by engaging in this work. Open Men’s Group is a container for men to share vulnerably without receiving judgment or feedback. We believe that emotionally mature, powerful, compassionate, and purpose-driven men will help heal some of society’s deepest wounds. We support the powerful brilliance of men and we are willing to look at, and take full responsibility for, the pain we are also capable of creating – and suffering. We care deeply about men, our families, communities, and the planet. Visit ManKind Project USA to discover more. https://mkpusa.org/

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

Let’s try this popular Italian restaurant in Reynoldsburg. This is the menu: https://scaliristorante.com/#4e468054-0235-43e2-81c2-44e061341e9e

We meet at lunch each week and each meeting follows a fairly organized agenda. First all participants pass their business cards around. Then each member and guest is invited to give a one-minute overview of their company and what is a perfect referral for the week. We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot. Bring plenty of cards!
