**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.

This month's prompt concerns the idea of the “warrior philosopher” (seemed appropriate in these times)--that is someone whose understanding of violence, power, and justice is forged through direct experience of war. We are looking at Major General Smedley D. Butler, a highly decorated U.S. Marine raised in a Quaker (pacifist) tradition who later became a prominent critic of American militarism (there is a wonderful biography of Gen. Butler called "Gangsters of Capitalism") Butler's argument in *War Is a Racket* (1935): that many U.S. interventions were driven less by national defense than by corporate and financial interests, with Butler portraying himself as an enforcer for business and Wall Street. We can consider the moral ambiguity of his insider critique—whether complicity strengthens or undermines credibility and also consider some of the concrete reforms he proposed (e.g., “conscript” capital before soldiers, restrict the military to coastal defense, and have only those who fight decide on war). Butler’s life arc clearly changed from pacifist upbringing to warrior to antiwar crusader—and asks whether true understanding of peace requires firsthand knowledge of war, and what that implies about the cost of suffering. So do we need to suffer to understand suffering? Do we have to experience war to appreciate peace? As one more question: in the movie "A Few Good Men" Jack Nicholson's character says that "you have the luxury of not knowing what I know" so do most of us go through life oblivious to real violence and suffering? See you at Drunken Philosophy!

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
