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

One of our favourite locations for our first trip of 2026, McCrae Lake is in in the south, and will have warmer weather than the more northern lakes. This is an easy trip, good for novice paddlers, to test your new kit, or get back into shape. McCrae Lake is a large lake divided into several bays, on crown land, close to Toronto. The water quality is excellent, and there is good fishing. The backcountry campsites are large, quiet, have a steel grill and thunder box, and are free. More information on McCrae Lake: [https://www.ontario.ca/page/mccrae-lake-conservation-reserve-management-statement](https://www.ontario.ca/page/mccrae-lake-conservation-reserve-management-statement) The water may be warm enough to swim, and the bugs will not be out yet. Fun activities include hiking on wilderness trails, paddling up and down rapids, swimming with rattle snakes, diving off of cliffs into the lake, and dragging out the bodies of people who tried to do all of those things. Watch for the Five-Lined Skink. Or, you can relax in a hammock. McCrae Lake is very popular. We may have to wait for room in the parking lot, and empty campsites. **If anyone in our group can go into McCrae Lake on Thursday or Friday to secure a campsite, it would be appreciated.** Arrive early Sat. AM. to get a parking spot or after 3:00 PM when day hikers go home. We are not required to go home on Monday night. You can continue to camp for as long as you wish. Carpooling is recommended to reduce the number of parking spaces required. Most areas of the lake have cell service sufficient for text messages and data. One portage, 150 metres, well used trail, over a high granite ridge. Paddle distance: 5 km. Canoe rentals should be available if you reserve one in advance: Swift Canoe Georgian Bay [https://swiftoutside.com/georgian-bay/](https://swiftoutside.com/georgian-bay/) Wawautosa Marina [https://www.wawautosa.ca/](https://www.wawautosa.ca/) Driving Distance: From Hwy 7 and Hwy 400, Vaughan Metropolitan Center: 142 km., 1 hour 30 mins. **ACTUAL LOCATION:** **McCrae Lake Parking Lot Muskoka District Municipality, ON** **44.92206400775243, -79.7772977860336** **Please fill in the Spread Sheet below:** https://docs.google.com/spreadsheets/d/1V1iupkEzye3zj5O8Sagri1FZyVLGOeM1EDy4ZkgcABo/edit?usp=sharing

Join us on Wednesday, May 13th, 2026, at 6:30 PM for a session presented by **Aidan Foster** on using Claude Design, Anthropic's new AI-assisted design tool, to vibe design web user interfaces. **Event Details:** * **Location:** CSI Spadina - 192 Spadina Ave., Toronto, ON M5T 2C2.

We'll look at: * Generating a design system from a Figma file * Iterating with the tweaks panel and edit mode * Prototyping UI from existing code and screenshots * Where Claude Design fits alongside Figma and Claude Code **Your Voice Matters:** Got ideas for future presentations or want to be a speaker? Reach out to Pierre or Aidan – we're always looking for speakers and new insights! **Drinks & Discussion:** Stay after the presentation for drinks and more Drupal talk at [Hotel Ocho](https://maps.app.goo.gl/4HF9ooz2Ki9B8o577) **Special Thanks to our Sponsor:** A big shoutout to[ Kalamuna](https://www.kalamuna.com) for providing the CSI space for our meetup. Looking forward to seeing old friends and new faces alike. Let's make this a great meetup for Toronto's Drupal community, going strong since 2006!

**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).

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. Prior to working at South Western, he worked as a Systems Engineer at Pinnacle Data Systems in Groveport. He graduated in 2005 from The University of Toledo with his Bachelor’s in Computer Science and Engineering, and a minor in Mathematics. Robert resides in Obetz with his wife, and their 15 and 12 year-old daughters. He was also just elected to his 3rd four-year term on the Obetz City Council.

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.
