**🏛️ 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://tally.so/r/81LP4A), 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: * 19:00-19:15 - People arrive and chat, get to know each other before the official start. * 19:15-19:25 - 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. * 19:25-20:45 - 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. * 20:45-21:00 - 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. * 21:00 - 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 is operated entirely on voluntary donations! If we are meeting in a café, buy a beverage! Donations are 100% voluntary, but they help us to bring the gift of deep conversation to people around the world. If you'd like to support, you can [donate here](https://www.zeffy.com/en-CA/donation-form/donate-to-practical-philosophy)! (Practical Philosophy is a registered Canadian charity) **💛 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://tally.so/r/81LP4A) 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/). 🤝**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.

The Test Tribe 13th Toronto Meetup – From Tests to Trust: How QA Creates Value That Outlasts Technology Shifts Tools change. Frameworks evolve. AI reshapes workflows. But one thing remains constant: the expectation that QA delivers value. In a world of rapid technological change, the real question isn’t what tools we use - it’s how QA creates trust, clarity, and better decisions across teams. At the 13th Toronto Meetup, we step back from tools and trends to explore a deeper question: What does quality really mean to the business - and how can QA deliver it consistently, regardless of technology shifts? **Event Details** * **Date: April 29th, 2026 (Wednesday)** * **Time: 6:00 PM – 9:00 PM ET** * **Venue: Tribal Scale** * **Maps Link:** https://maps.app.goo.gl/hqUyAVXKLQhPFsUK6?g_st=ic **Session: From Tests to Trust: How QA Creates Value That Outlasts Technology Shifts** **Speaker: Youssef Menkhour** **About the Session** Technology in QA is evolving rapidly - but expectations from stakeholders often remain unchanged. In this session, Youssef Menkhour brings a QA Director’s perspective to explore: * What different roles (engineering, product, business) actually expect from testing * How QA creates value indirectly, beyond test execution * Why traditional outputs - tests, reports, meetings - often fail to drive real decisions * How to simplify QA practices to better support clarity, alignment, and impact This talk challenges conventional thinking and focuses on how QA can move beyond activity-driven work to become a driver of trust and decision-making within organizations. **Key Takeaways** * Understand what stakeholders truly expect from QA * Learn how QA delivers value beyond test cases and execution * Simplify testing outputs to better support real decisions * Shift from activity-driven QA to impact-driven quality engineering * Build practices that remain relevant across changing technologies **About the Speaker** Youssef Menkhour is a Director of Quality Assurance with 15+ years of experience leading enterprise and SaaS-focused QA organizations across industries including insurance, banking, media, and telecommunications. At Alithya, he advises clients on quality modernization, helping organizations adopt automation-first strategies, shift-left testing, and CI/CD-aligned delivery models. Youssef is passionate about redefining QA’s role - from a supporting function to a strategic contributor that drives trust, alignment, and long-term value. **Why You Should Attend** * Gain a leadership perspective on the future of QA * Learn how to create value beyond tools and frameworks * Understand how to align QA work with business outcomes * Rethink how testing supports decision-making * Connect with Toronto’s QA and tech community **About The Test Tribe** The Test Tribe is the world’s largest software testing community, empowering testers globally since 2018. With 700+ events and 150K+ members across 130+ countries, we bring testers together to learn, grow, and connect through meetups, conferences, cohorts, masterclasses, and more. By RSVPing, you agree to our Terms and Conditions and Privacy Policy and consent to be contacted by The Test Tribe and our event partners.

Don't be disappointed if you don't see a bunch of people attending. I advertise this on multiple platforms and the class usually sells out. Improv comedy uses several techniques to create laughter. These include, creating an atmosphere free of judgement, saying 'yes', active listening, being positive, putting your focus on others, and the importance of play and laughter. Not coincidentally, these are the same things that happen to us naturally when we are bonding with another person. In this class, we'll explore these techniques not with the goal of being funny, but with the goal of being people that other people want to be around. The organizer, Ralph MacLeod, is a co-founder of two independent improv clubs in Toronto - Bad Dog Theatre and Social Capital Theatre. He's been teaching improv for over 30 years. He also teaches these same techniques to several organizations including UofT, Google, Kraft, Shopify and many, many more. Please feel free to ask any questions you may have! FAQs and Good To Know.... After every event, a group from this class sit down and have a drink together so be prepared to stay if you want! Of course, you don't HAVE to. You also don't have to be single or bring a friend. The vibe of this class is much more 'making new friends' than a 'singles' mixer'. We usually run to 8:15 so pay for extra parking!

A hands-on workshop on turning insights into ideas that actually hold. Most ideas aren’t bad. They’re just… premature. ​We’re trained to move fast, jump to solutions, and make things look good quickly. ​But good design doesn’t come from speed. It comes from **seeing differently.** ​This session is about breaking that habit. ​This hands-on workshop explores how ideas actually emerge i.e through tension, constraints, and collaboration and not just creativity. ​ **👉 To secure your spot, please register via [Luma](https://luma.com/caozni5i): https://luma.com/caozni5i** (*Meetup RSVPs don’t guarantee a seat*) # ​**What we’ll do:** ​**Start with people (but not in a fluffy way)** ​Map real experiences ​Surface assumptions ​Interrogate what we think we know ​ ​**Push beyond obvious ideas** ​Generate more (and worse) ideas — on purpose ​Break out of default thinking patterns ​ ​**Make it real** ​Work with constraints ​Shape direction ​Turn messy thinking into something tangible ​ ## ​**What you’ll take away** * ​Why most teams default to shallow thinking * ​How to actually *practice* divergent thinking (not just talk about it) * ​What it means to move from insight → concept * ​How constraints make ideas stronger, not weaker ​**Who this is for** * ​Professionals who want to relax, nerd out, and build fun things * ​Designers who are tired of surface-level workshops * ​People who jump to solutions (you know who you are) * ​Anyone curious about how ideas *actually* come together ​ ​**About Service Design Drinks (SDD)** ​SDD is a community of practice for people interested in service design. ​We host casual, hands-on sessions to learn, share, and grow together - no fluff, just thoughtful work and conversation. ​ ​**Agenda** ​5:30 pm \| Arrival \+ settle in ​6:00 pm \| Workshop session ​7:30 pm \| Stay back and connect

The playbook for AI agent integration is becoming predictable: build an MCP server, expose your APIs as tools, and define the rules in prompts. That approach works, but it often pushes workflow and guardrails into client-side logic, where they are harder to enforce and easier to bypass. This talk presents a different approach. HATEOAS (Hypermedia As The Engine Of Application State)—a largely overlooked part of REST—allows an API to describe allowed actions and constraints at runtime. That makes it a natural fit for agents, which need clear, machine-readable guidance about what they can safely do next. We’ll show this in action with MoneyMate, an AI agent that performs sensitive operations such as money transfers. Using the Spring HATEOAS project, the agent is guided entirely by the API rather than by hardcoded tools or fragile prompt logic. AI hype aside, this is ultimately a talk about architectural validation. For years, HATEOAS was the hill REST purists loved to die on—complete with finger-wagging about “doing REST correctly”—while everyone else quietly shipped simple JSON and moved on. It turns out the purists weren’t wrong—just 20 years early. Come see why that extra structure finally pays off when your client is an LLM. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu. Please consider helping to support the venue by planning to have supper during the talk. **Speaker Bio** Adib Saikali is a distinguished engineer at Tanzu by Broadcom, focused on helping Tanzu’s largest customers design and build cloud native applications and platforms using Spring and Kubernetes. Adib is the author of Securing Cloud Applications a book that teaches application developers the fundamental security technologies and protocols required to secure cloud native applications. Over the past 25 years Adib has worked at startups and global enterprises on numerous software systems in a variety of roles, from software developer, architect, agile coach, and CTO. He has developed a 360-degree view of what it takes to build software systems efficiently, and economically.

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.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
