**Welcome to Miss Bachata & Miss Salsa!** **Spring is in the air, and with it comes the promise of new beginnings, fresh energy, and the joy of connection!** As the season of renewal unfolds, we invite you to step into the rhythm of community, dance, and celebration at Miss Bachata & Miss Salsa. My objective has always been to create a different kind of social gathering—one that is open, non-judgmental, and safe. A place where you can meet people just like you, where socializing and dancing come together to help build community and tear down the walls that separate us. Here, we make new friends, feel a sense of belonging, and enjoy the calmness that comes from knowing we are in a safe and welcoming space. Many times, I have been asked, “Why host an event on Monday night?” Many people escape on the weekend and dread Mondays when they return to work. I believe that if you dance and socialize on a Monday, you infuse your week with joy and positive energy, giving your life balance and helping you face your challenges with enthusiasm and confidence. We’re also thrilled to announce that our trial of advanced Bachata lessons, which began last September, has been a resounding success! Building on this momentum, we’re excited to offer an enhanced schedule for 2026. Our dance evenings will now feature three hours of classes: one hour of beginner to intermediate Bachata, one hour of advanced Bachata, and one hour of beginner to intermediate Salsa. As always, the entrance fee remains $15 for a night of 2 lessons and social dancing. For those interested in the advanced Bachata lessons, there will be an additional $5 fee. Here’s our updated schedule: **Miss Bachata – Main Ballroom** 🕖 7:00 pm – 8:00 pm: Beginner to Intermediate Bachata Lesson (No partner required) 🕗 8:00 pm – 12:00 am: Social Dancing **Miss Salsa – Round Room** 🕖 7:00 pm – 8:00 pm: Advanced Bachata Lesson (+$5) **NEW** 🕗 8:00 pm – 9:00 pm: Beginner to Intermediate Salsa Lesson 🕘 9:00 pm – 12:00 am: Social Dancing ✨ **Additional Details:** ✔️ Free Parking ✔️ Full Bar (Free Water, Beer: $5.75) Over the past decade, organizing Latin dancing events in Mississauga has been a labor of love. Our mission has always been to foster a sense of community, proving that the connections we share are far stronger than the differences that divide us. Loneliness is a growing concern, with over half of U.S. adults and many Canadians experiencing its effects. The COVID-19 pandemic has only heightened this issue. Harvard University's long-term study on happiness, which began in 1938, highlights the detrimental impact of loneliness on health. People with strong social connections experience slower mental and physical decline and greater overall happiness compared to those who are isolated. Here are some key findings from the study: 🌿 Close ties help delay mental and physical decline more than money, fame, social class, IQ, or genetics. 🌿 Relationship satisfaction is a better predictor of aging well than cholesterol levels in middle age. 🌿 A strong sense of community improves memory function. 🌿 Loneliness can be as harmful to health as smoking or alcoholism. And there’s hope! Strengthening our relationships and supporting community initiatives can combat loneliness and build healthier, happier lives. Miss Bachata & Miss Salsa provides a wonderful opportunity to make new friends, expand your social circle, and enjoy a safe, welcoming, authentic environment. Bring your open heart and a smile, and we’ll take care of the rest. 🌸 **Cheers to a season of renewal, joy, and community!** 🌸 **Anna G.** https://www.facebook.com/groups/1871491806494168/ https://www.facebook.com/EventsByAnnaG

**This is a ticketed event. Please register at [this link](https://luma.com/n5d2q50u).** ​The Platonic Representation Hypothesis (Huh et al., 2024) proposes that neural networks are converging toward a shared statistical model of objective reality, offering a Platonic explanation for the growing representational similarity observed across models of different architectures, datasets, and modalities. In this talk, Robert Adragna argues that such convergence is computationally intractable in practice. Truly representing reality would require models to recognize the same real-world concept across all its possible appearances — a form of robustness that theoretical and empirical work suggests is infeasible to achieve at scale. He proposes an alternative account: representational convergence reflects shared structural assumptions embedded in training data, not the discovery of objective reality. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

\*\* We are moving to heylo.com. Please join us there to sign up for any upcoming events (although you will still be able to sign up on Meetup for the next couple of months). \*\* We will be holding our monthly in-person Skeptics in the Pub event on the second Tuesday of every month. We are an informal group of scientific skeptics who promote critical thinking, reason, and empirical evidence, advocating for the scientific method to evaluate claims while opposing pseudoscience, superstition, and anecdotal evidence. We will get together for a social event to say hello to people we may have only met on-line, to reconnect with some long-time acquaintances, and to meet new people who may be interested in skepticism. We will not be having a presentation or a speaker, just a chance to sit down and have a meal and/or a beverage and a conversation with a pleasant group of fellow skeptics. (Monthly on-line Zoom meetings will continue as usual, on the third Friday of every month). Our previous venue, Prenup Pub, has closed, so we will meet this month at a **new location**, The Frog: A Firkin Pub, 4854 Yonge St, North York, ON M2N 5N2. Google Maps says it is about a 3-minute walk (200 m) from Sheppard-Yonge subway station, north of Sheppard, on the west side of Yonge. Food and beverages are available from the menu. Foods include a full menu from soups, salads, and appetizers to burgers, sandwiches, entrées and dessert. The beverage menu includes about16 different beers on tap, many bottled beers, ciders, seltzers, and coolers, as well as a selection of wines, various cocktails, and non-alcoholic drinks. When you arrive, just ask where the "Skeptics" are. If you plan on joining us, please register so we can estimate the number of attendees.

**This is a ticketed event.

In a 2023 paper, Gillian Hadfield and Jack Clark propose a third path: regulatory markets, where governments license private regulators and require AI companies to purchase regulatory services from them. ​Kathrin Gardhouse will walk us through the paper's core argument and what it would actually mean in practice: how regulatory markets differ from existing approaches, what problems they solve, and what they might get wrong. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City. He has worked there for 17 years, serving previously in the roles of Data Analyst, Programmer, and Operations Coordinator.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. 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.

**Abstract:** This is a practical playbook for building a production-grade data lakehouse. It walks through foundational principles — naming conventions, least-privilege access, automated CI/CD testing — before diving into medallion architecture.
