**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

Certificate validation is a crucial step in Transport Layer Security (TLS), the de facto standard network security protocol. Prior research has shown that differentially testing TLS implementations with synthetic certificates can reveal critical security issues, such as accidentally accepting untrusted certificates. Paracha et al. introduce a new approach, MLCerts, to generate synthetic certificates that leverages generative language models to more extensively test software implementations. Recently, these models have become (in)famous for their applications in generating content, writing code, and conversing with users, as well as for "hallucinating" syntactically correct yet semantically nonsensical output. The authors leverage two novel insights in their work: (a) TLS certificates can be expressed in natural-like language, namely in the X.509 standard that aids human readability, and (b) differential testing can benefit from hallucinated malformed test cases. MLCerts finds significantly more distinct discrepancies between the five TLS implementations OpenSSL, LibreSSL, GnuTLS, MbedTLS, and MatrixSSL than the state-of-the-art benchmark Transcert. ​​​**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).

Modern Microsoft Fabric projects often start with built‑in Git integration and deployment pipelines—but at enterprise scale, those capabilities alone are rarely sufficient. As environments grow in size and complexity teams need more advanced tools and patterns to manage Fabric artifacts reliably across development, test, and production. In this session, we will: \- Review common enterprise lifecycle challenges in Microsoft Fabric \- Introduce advanced DevOps tooling and automation patterns used to address them \- Walk through a realistic implementation pattern that shows how these tools fit together in practice This session is designed for data and platform engineers and architects responsible for operating Microsoft Fabric in production. If you’re already using Git integration and deployment pipelines and are looking to extend them with more scalable, repeatable, and enterprise‑ready CI/CD practices, this session will help you understand when and how to go beyond the defaults. *Come at 5:30 pm have some pizza and chat for a bit. The presentation starts at 6:00 pm.*

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/yvAGbh4PpD **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
