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. If you RSVP and can't make it, please update your status so someone on the waitlist can take your spot.

Golf courses are not just for golf. In winter, city-owned courses become cross-country skiing and snowshoeing territory. Of these, the Don Valley Golf Course has the largest and most scenic routes. It goes across rivers and under massive highways. Toronto's only ski lift is just outside its boundaries, which we can visit if the gate there is unlocked. After romping through the golf course, we'll continue exploration in the Hoggs Hollow neighbourhood. It has some historical buildings, a fancy French restaurant, and a 1850s tavern. Heading south along Yonge Street, we'll reach a clutch of eateries, where you can choose between Georgian, Indian, or Thai food. This event depends on snow. If there is heavy snowfall, you're encouraged to ski or snowshoe the golf course portion of the hike. If there is no snow and ice, we'll just walk. Walking in heavy snow is not recommended. If you must, wear muck boots and/or traction aids. After the golf course, the rest of the hike will be on foot. **Highlights** 1. Don Valley Golf Course main building (depart 12pm) 2. Golf turf blanketed in snow (or barren and grey) 3. Hogg's Hollow Bridge 4. Earl Bales ski lift 5. Don Valley Golf Course main building (depart 1:12pm) 6. Auberge du Pommier 7. C W Jeffrey's house 8. St. John's York Mills Anglican Church 9. York Mills Centre (depart 1:40pm) 10. Miller Tavern 11. Tamada Georgian Restaurant / Mumbaikar 12. Pii Nong Thai (arrive 2:05pm) **Neighbourhoods** Armour Heights > Hoggs Hollow > Bedford Park **Map** [https://www.google.com/maps/d/edit?mid=1clcrZAR9LCTyev1-8BHf3pNAgyS-Muw&usp=sharing](https://www.google.com/maps/d/edit?mid=1clcrZAR9LCTyev1-8BHf3pNAgyS-Muw&usp=sharing) Moderate incline going down from golf course, potentially covered in ice. Stairs to St John's York Mills Anglican Church. Uphill along Yonge St from York Mills to Glen Echo. Free admission to golf course in winter. **How it works** Hike starts punctually.

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.

Anyone is welcome to join this hike but we are especially inviting our new members (and prospective members) to learn about our hiking program and how our guided hikes are classified and described in the hike schedule and what you should bring with you on hike. We will explore Crothers Woods in the Don Valley, nature in the heart of the city, which will present some moderate challanges with it's ups and downs giving it's Level 2 classification. The actual route will depend on conditions of the day to keep it a moderate level hike. Please bring ice traction cleats (mandatory) for a safe hike. We'll have a brief outdoor snack/lunch stop along the route. We will return to Todmorden Mills at the end of the hike. Note transit users will need to ascend the fairly steep hill on Pottery Road at the conclusion of the hike. Washrooms are available at the Todmorden Mills Site. On this introductory hike we will: * Discuss how a hike is classified (Level 1,2,3, Moderate/Fast, etc) * Discuss the variables that affect the difficulty of any particular hike * Discuss why different people have different perspectives on the difficulty level of the same hike * Demonstrate some terrain that would raise the difficulty level of hike hiking * Help you know you have the information required to choose the hikes right for you Register At BTC website : [https://hikes.brucetrail.org/event/crothers-woods-introductory-hike/2026-02-22/](https://hikes.brucetrail.org/event/crothers-woods-introductory-hike/2026-02-22/) Please register at above so we have you on the waiver form

**Abstract:** The Advanced Photon Source (APS) is an X-ray light source at Argonne National Laboratory where researchers perform imaging, diffraction and spectroscopy experiments at 68 specialized beamlines. APS recently completed a major upgrade that made it the brightest synchrotron in the world and upgraded many of the beamlines to take advantage of the dramatically brighter, more coherent beam. These new capabilities are increasing the facility’s raw data production from <10 PB/year before the upgrade to >100 PB/year once all instruments are back online. To meet this data challenge, the APS Beamline Data Pipeline project team is partnering with beamline staff to develop and deploy science data pipelines that use a common set of open-source software tools (many written in Python) to link instruments with the Polaris supercomputer at the Argonne Leadership Computing Facility (ALCF) for data processing. This talk will describe the APS data systems, our file-based and streaming pipeline templates, and some of the open-source software we use to extract scientific insights from beamline data. **Audience Takeaway:** Open source Python data acquisition and analysis tools are ubiquitous at the APS. Many of the packages that are mentioned can be found at [https://github.com/AdvancedPhotonSource](https://github.com/AdvancedPhotonSource). This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://iit-edu.zoom.us/j/89607999223?pwd=qIKKzrkJIay3jeIu8tE0jfWdOy7iRx.1](https://iit-edu.zoom.us/j/89607999223?pwd=qIKKzrkJIay3jeIu8tE0jfWdOy7iRx.1) **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W.
