Power grids run on protocols that were never designed to be secure. Modbus doesn't authenticate. MQTT trusts whoever connects. State estimation believes whatever data you feed it. This month, Parham Mohammadi shows what happens when you exploit all of that. **THE TALK** Parham built a full ICS attack simulation lab and ran real attack chains against it. False data injection into state estimation. Modbus register overwrites. MQTT broker takeover. Chained attacks against distributed energy resources. The operator dashboard stayed green the entire time. If Ukraine 2015 and Industroyer taught us anything, it's that this isn't theoretical. **THE SPEAKER** Parham Mohammadi — Postdoctoral Researcher, York University Parham spent six years at York doing his PhD on power systems simulation. The CPPS-SEC Lab he built for this research simulates real ICS attack chains against power grid infrastructure — the same lab he's demoing at this talk. ***ARRIVAL WINDOW — PLEASE READ*** Doors open at 6:15 PM and close at 6:40 PM. Our volunteer at the gate can only let people up during this window. After 6:40 PM, there will be no one downstairs to let you in. Plan accordingly.

While we pop up in various locations throughout the city, we have curated this space to serve as a peaceful environment for our session. **Intentional Intimacy:** To maintain a calm and focused atmosphere, we intentionally limit our gatherings to **12 guests**.

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!

Join us for a Toronto meetup of creative coders! Instead of our usual show-and-tell, this will be a **work session!** If you're looking for some motivation to tinker on a creative project, now's your chance! **What is creative code?** *Creative coding* refers to anything with an artistic component that uses code as a medium. We welcome artists who use code (for visuals, audio, poetry, or whatever else), designers, animators, toolmakers, researchers, or just enjoyers and people looking to learn more! **Location:** Impact Kitchen on Queens Quay (88 Queens Quay W, Toronto, ON M5J 0B6) **Join our discord** if you want to talk to everyone before/after the event, or have any suggestions for things you'd like to see or do!

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/Da9fZFxPfs **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.

**Welcome to the inaugural meeting of the International Relations / Foreign Policy Group Columbus!** This group brings together students, professionals, academics, and anyone interested in global affairs, diplomacy, and geopolitics. Our first meetup will be an informal discussion focused on current international developments and global trends.

**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** *Spec-Driven Development with GitHub Spec-Kit: From Intent to Implementation* Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
