A lot of travelers spend their time chasing: • the next card • the next bonus • the next redemption • the next “hack” But the travelers who consistently get the best results? They think differently. They make better decisions. They understand leverage. They know what actually matters… and what doesn’t. And often, the biggest breakthroughs don’t come from learning something new. They come from finally understanding the game itself. That’s what makes sessions with JGOOT Founder Joel McDonald different. Because this isn’t just about points. It’s not just about cards. It’s not just about travel. It’s about the mindset, strategy, and decision-making process behind building a life where extraordinary travel becomes normal. In this special live strategy session, Joel will be diving into the ideas, perspectives, and playbook principles that continue to shape the way smart travelers approach points, travel, and opportunity. It’s time for: **The Founder’s Playbook: A Live Strategy Session with Joel McDonald** Inside this session, Joel will cover: • The strategic shifts changing the way smart travelers approach points and travel • Common mistakes that quietly cost people opportunities, flexibility, and value • How experienced travelers think differently from beginners • The difference between collecting points… and building a real travel strategy • Why simplicity often outperforms complexity in the long run • The mindset and habits that lead to more consistent travel success This isn’t about chasing hype. It isn’t about finding one magic trick. It’s about learning how to think strategically in a world full of noise, distractions, and endless “travel hacks.” And when you understand the playbook behind the playbook… you stop reacting to opportunities randomly… and start creating them intentionally.

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/27ja5gwl Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity. ​ ​**​Agenda:** ​​6:00 - 6:30 PM - Welcome and mingle 6:30- 6:45 PM - Introductions 6:45 - 7:30 PM - Talk 7:30 - 8:00 PM - Wrap up **​​Description:** ​If you have ever shipped a model, watched your metrics improve, and later learned from your users that something was wrong, the metrics were always wrong. You just didn’t know it yet. An evaluation consists of three components, a benchmark, a scorer, and a claim about what a score represents. Each component has its own weaknesses. Benchmarks can suffer from narrow coverage, contamination, or saturation. Scorers are often chosen for ease of automation or computation rather than for their alignment with user outcomes. And the claim connecting a score to reality is rarely made explicit. These gaps compound across the model development lifecycle. When metrics improve, teams treat that as a signal and optimize directly against it, which is how a measurement problem becomes a model problem. This talk maps where evaluations can go wrong, considers counterarguments, and ends with practical advice for building better ones. **​Speaker Bio:** ​Mary is a Senior Applied Scientist at Relativity, tackling data science challenges in the e-discovery and legal tech space. She is also an organizer for Women and Gender eXpansive Coders DC (formerly Women Who Code DC), fostering a community dedicated to empowering women and nonbinary individuals to excel in their careers. Mary's experience spans various domains. She has developed data science solutions related to job search and career progression at Teal, cybersecurity challenges at LiveAction Software, and commercial and government consulting at Mosaic Data Science. Before venturing into the field of data science, Mary conducted and published research pertaining to the cellular and molecular mechanisms underlying neurodevelopment at the National Institutes of Health. In other words, she has dissected and imaged a lot of fruit fly brains. She holds a M.S. in Data Science from The George Washington University and a B.A. in Biological Sciences from Cornell University

**\*\*You must purchase a ticket [here](https://sommcircle.clubexpress.com/content.aspx?page_id=4002&club_id=650343&item_id=2926832). \*\*** Ever find yourself nodding along at a wine tasting, wishing you knew what to actually say — or even what to look for? This is the evening that changes that. Speak Fluent Wine is a hands-on tasting experience designed to teach you the exact framework wine professionals use to evaluate what's in the glass. You'll go from "I just know what I like" to understanding \*why\* you like it — and having the words to say so. Here's what we'll cover: ?? Sight — What color and clarity reveal before the first sip ?? Nose — How to train your sense of smell and identify aromas with confidence ?? Palate — Decoding what your taste buds are picking up: sweetness, acidity, tannins, body, and finish ?? Structure — How the elements of a wine interact, including how acidity softens sweetness and tames tannins ??? Language — The vocabulary professionals use, demystified and made practical Once we've broken down the framework, Total Wine's expert staff will lead a short guided tasting — putting everything you've just learned directly into practice. Snacks and water will be provided. Cost is $25 No experience necessary. No judgement. Just great wine, a welcoming atmosphere, and the confidence you've been waiting to find. **\*\*You must purchase a ticket [here](https://sommcircle.clubexpress.com/content.aspx?page_id=4002&club_id=650343&item_id=2926832). \*\***

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
