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.

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.

By the late 1860s and 1870s, it blossomed into the world's largest distillery. And it's a historic jewel on our waterfront, a place to stroll, meet up, have a coffee or a bite to eat. Come and explore one of Toronto's most fascinating neighbourhoods. And get a bird's eye view of how Toronto developed around the time that Canada became a country in 1867. But let's not forget the district to the north. The area near the banks of the Don River on and around River Street and Queens Street East was the core of the Beer Industry. Let's take a look at how the two industries came together and who was involved. For a quick peek at the walk check out this link on my YouTube channel at https://youtu.be/xAp97lI_20A This walk is for all fitness levels. The meeting place for our walking adventure is opposite the streetcar loop on Cherry Street just south of Mill Street at the eastern edge of the district.

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

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
