APIs power virtually every web and mobile application, accounting for over 80% of all Internet traffic. And APIs are under attack. Gartner states APIs have become the “most frequent attack vector," resulting in hundreds of highly successful, high profile breaches. This API security presentation covers 1) why attackers love APIs, 2) real-world breaches (and how they map to the OWASP API Security Top 10), and 3) best practices to keep APIs secure.

CALLING ALL WINE LOVERS

**🏛️ 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/ZjaPO0), 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** * ​What will we talk about? What's the topic? ​The topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://tally.so/r/ZjaPO0). * 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, but it's not required. * 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 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/ZjaPO0) 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 - Making Philosophy Available To All.** ✨ Practical Philosophy hosts weekly, in-person meetups in over 25 countries and 50+ chapters, including Canada, Spain, Japan, Mexico and many more! 🗺️ \*\*\* Join our [Whatsapp group](https://tally.so/r/ZjaPO0) 👈 Follow us on [Instagram](https://www.instagram.com/practicalphilosophyclub) 👈 Our [website](https://www.practicalphilosophy.club/) 👈

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.

[Summary] This meetup is for those who are interested in code, web development, design, cloud, or AI. All levels are welcome, so feel free to bring your laptop and discuss what you are working on or what you are learning. You can share your projects and ideas with other participants freely. There are outlets and WiFi, drinks are about $5 for tea, they take card only. [Price] Attendance is FREE. But you need to buy something from the venue. [Policies] \- We do not tolerate harassment of our members \- We remind users that that this meetup is intended for networking and hobby development\, and any attempts at using this meetup event as a dating platform will not be not be tolerated Further information: https://torontostack.exchange/

​🚀 Join ProductTank Toronto for a night exploring how product people and founders are building **productive AI agents**—from configuring Notion agents to orchestrating systems that design, build, and ship real products. ​This session is all about **execution**: how AI moves beyond experimentation into real workflows that extend your capacity and actually get things done. ​If you've attended a Notion Toronto Community event before, you may already know our speakers. This time, they’re bringing their real-world AI practices to the ProductTank stage. Featuring: [Dave Mence](https://www.linkedin.com/in/dave-mence/) and [Josh Gonsalves](https://www.linkedin.com/in/joshgonsalves94/) ## 🎤 **Dave Menceles, Program Ops Manager @ Notion** ***Quality In, Quality Out: Putting in the Human Work to Make AI Agents Shine*** **​About Dave:** ​Dave manages operations for a group of 120+ third-party Notion experts in one of Notion’s certified consultants programs. He leans on a handful of Notion Custom Agents to help him perform his day-to-day work that would otherwise extend way beyond his individual bandwidth. **​About his talk:** ​Dave will share how his Q&A agent helps to support the members of his program with the deep program knowledge he’s imparted to the agent. He’ll also give an short guide on how to set up your own Notion Custom Agents that can work around the clock to perform helpful work on your behalf. ## **Josh Gonsalves, Founder @ Contraverse** ​**AI That Builds AI: Orchestrating Agents Into a Real Product Team** **About Josh:** ​Josh is a Toronto-based founder building Formive, an AI platform for creating and sharing powerful AI tools and lead magnets without any code. His work focuses on turning AI into a leveraged system that can research, plan, build, and ship real products autonomously. He hasn’t written a single line of code. Instead, he directs AI systems that do. ​**About his talk:** ​Josh will break down how he uses AI coding tools like Claude Code, Codex, and Cursor as a coordinated team of AI designers and engineers to build and ship a real product from scratch. He will show how Agent Skills, MCPs, and structured workflows enable these models to collaborate, handling everything from product research and planning to coding, review, bug fixing and shipping production-ready software. This talk are especially **relevant for non-technical** founders and Product Managers. It demonstrates how you can create solid, production-ready software without being a traditional developer by directing systems instead of writing every line yourself. ​Spots are limited—see you there! 📍 BrainStation @ The Well 🗓️ Thursday\, Apr 16th\, 2025 \| 6:00 p\.m\. \- 8:00 p\.m\. 🎟️ Free to attend [hashtag#ProductManagement](https://www.linkedin.com/search/results/all/?keywords=%23productmanagement&origin=HASH_TAG_FROM_FEED) [hashtag#AIForPMs](https://www.linkedin.com/search/results/all/?keywords=%23aiforpms&origin=HASH_TAG_FROM_FEED) [hashtag#TorontoTech](https://www.linkedin.com/search/results/all/?keywords=%23torontotech&origin=HASH_TAG_FROM_FEED) [hashtag#ProductTank](https://www.linkedin.com/search/results/all/?keywords=%23producttank&origin=HASH_TAG_FROM_FEED) [hashtag#AIExecution](https://www.linkedin.com/search/results/all/?keywords=%23aiexecution&origin=HASH_TAG_FROM_FEED)

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

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.
