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.

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

This is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance. Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology Life Improvement Center of Central Ohio.
