**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.meetup.com/LatinDanceMeetup https://www.facebook.com/groups/1871491806494168/ https://www.facebook.com/EventsByAnnaG

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.

This is a ticketed event. Please register at [this link](https://luma.com/sdhf0qqc). Jackson Kaunismaa presents his new paper “Eliciting Harmful Capabilities by Fine-Tuning on Safeguarded Outputs”. He will discuss why output-level safeguards on frontier models don’t actually make the ecosystem safe, and how anyone with an open-source model can fine-tune it on adjacent-domain outputs from safeguarded models to recover a large fraction of the capability gap between open-source and frontier models on harmful tasks. ​​​**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).

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Communication is everything in life You are only as successful as your ability to communicate. \- What if you could confidently talk to anyone? \- What if you had the ability to calmly control every conversation? \- What if you could close that sale\, ask for that date\, make new friends\, repair problematic relationships\, get that raise\, or effortlessly express any idea with confidence? You can! The secret to success relies on your ability or inability to effectively communicate. Attend a free seminar and gain a better ability to communicate.
