Bigger, Better, Bolder Miss Bachata & Miss Salsa
**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!** 🌸

Practical Philosophy Meetup - Toronto 🇨🇦
**NO PHILOSOPHY EXPERTISE REQUIRED!**
**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?**
Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎
Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic.
The goal is to help develop our Critical Thinking, Communication, and Community 🙌
**📓 HOW DOES IT WORK?**
Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/KRy6VgwgGRm3hSGeYlAzDE), along with jump-off points to get the conversation going.
When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture.
**General Meeting Agenda**
Each Practical Philosophy meet-up follows this general timeline:
* 19:30-19:45 - People arrive and chat, get to know each other before the official start.
* 19:45-19:55 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines.
* 19:55-21:15 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them.
* 21:15-21:30 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo.
* 21:30 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other.
**🧧PRICING?**
Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though!
**💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY**
**🗣** “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam
🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel
**🤓 FAQ**
* **Do I need to study or read anything to attend?**
No preparation is necessary. This isn’t a study of other thinkers. We want to know what you think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it.
* **Is there a specific philosophy that Practical Philosophy is focused on?**
The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school.
* **Is it mostly men that attend?**
Surprisingly, no! Although often, philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms.
* **Can I come alone?**
Of course you can, we encourage it :)
* **Can I be late?**
Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation.
* **Where do you meet?**
The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/KRy6VgwgGRm3hSGeYlAzDE) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/).
🤝**POLICY**
To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment.
**PRACTICAL PHILOSOPHY CLUB - Philosophy, everywhere. ✨**
We started in Practical Philosophy back in 2021 and there are now 50+ chapters in over 25 countries, including Canada, Spain, Japan, Mexico and many more! 🗺️

Eliciting Harmful Capabilities by Fine-Tuning on Safeguarded Outputs
**This is a ticketed event. Please register at [this link](https://luma.com/wbpv7ouu).**
In this talk, Talha Paracha will present insights from his latest research on using language models for improving software security ("Hallucinating Certificates", to appear at ICSE 2026).
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

**Discord Group for exchanging ideas, charts and strategies**
[https://discord.gg/SVYTSPh7](https://discord.gg/SVYTSPh7)
We will discuss options trading and investing strategies, as well as the skills needed to start. It is a **casual meetup to meet people who are interested in trading or building a career around it, especially algorithmically. No "financial gurus" are welcome.**
Join us for a meetup where we share trading ideas, and connect with others who share a common interest in investing.
Algorithmic trading is commonly used by large institutional investors and market makers, but it is also accessible to retail traders. It offers several advantages over manual or discretionary approaches—particularly in minimizing psychological errors that often impact human traders.
Some of the topics we usually discuss:
\- Reasons for investing
\- Limitations of being a retail trader
\- Practical tools: brokers\, APIs\, data sources\, real\-time implementation
\- Brainstorming ideas: strategies that may be working today
**Note this even is not sponsored or endorsed by any business where we are meeting. We are just using their space for casual meetup event.**
**Please no promotion of MLM, pyramid schemes, self promotion to paid services, affiliate promotion, paid subscriptions or similar stuff.**

A diffuse harm hurts many people a little; a concentrated harm hurts one person a lot. Other things equal, diffuse harm seems less bad than its concentrated counterpart. For example, shortening a billion happy lives by a second each seems less bad than shortening one happy life by a billion seconds (\~30 years). But this attractive thought is surprisingly difficult to maintain. Although many problems for such a view are known, a particularly vivid difficulty arises in cases that involve a sequence of social positions, each very similar to the last, such as the Fortuna’s Wheel scenario. In such cases, it follows, from rather minimal assumptions, that diffuse harm is just as bad as its relevantly similar concentrated counterpart. In response, some may wonder whether the parity of diffuse and concentrated harms holds only in these special sequential cases. But it can be argued that the approximate parity of diffuse and concentrated harms extends well beyond such cases. Specifically, it can be argued that in many realistic cases, a diffuse harm will bring about an outcome approximately as bad as a relevantly similar concentrated harm. Diffuse harm is easily underestimated.

This is a talk with audience Q&A presented by the University of Toronto's Centre for Ethics that is free to attend and open to the public. The talk will also be streamed online with live chat here [to be posted].
About the Centre for Ethics (http://ethics.utoronto.ca):
The Centre for Ethics is an interdisciplinary centre aimed at advancing research and teaching in the field of ethics, broadly defined. The Centre seeks to bring together the theoretical and practical knowledge of diverse scholars, students, public servants and social leaders in order to increase understanding of the ethical dimensions of individual, social, and political life.
In pursuit of its interdisciplinary mission, the Centre fosters lines of inquiry such as (1) foundations of ethics, which encompasses the history of ethics and core concepts in the philosophical study of ethics; (2) ethics in action, which relates theory to practice in key domains of social life, including bioethics, business ethics, and ethics in the public sphere; and (3) ethics in translation, which draws upon the rich multiculturalism of the City of Toronto and addresses the ethics of multicultural societies, ethical discourse across religious and cultural boundaries, and the ethics of international society.
The Ethics of A.I. Lab at the Centre For Ethics recently appeared on a list of 10 organizations leading the way in ethical A.I.: https://ocean.sagepub.com/blog/10-organizations-leading-the-way-in-ethical-ai

Humanist Program
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.
We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be.
Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
Going forward our meetings will be hybrid. You can meet us in-person or attend online

Prompt vs. Paintbrush
AI is changing how art is made. But when does it stop being your work and start being the machine’s?
This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?
We encourage audience participation during this event that will be moderated by Chris Slee.

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.
