The TAICO team is happy to announce our next meetup at the Adaptavist office in Toronto. Much thanks to [Adaptavist](https://www.adaptavist.com/) for hosting! **Wayfinding** * *Please be careful when using maps features on phones, some people have been redirected to a completely wrong address. The event is near Winners on Front St, which is just south, across the street, from Berczy Park (where the dog fountain is) so if you are not near that area, you are in the wrong place.* **Registration and Event Details** Our goal is to bring artificial intelligence and cybersecurity together. To do that, we need to explore what's happening in AI and what's happening in cybersecurity, and where the two intersect and collide. We're also working to understand how we solve problems in these areas, what that looks like, and how Canada can and will participate. With that in mind, we're pleased to announce our speaker and the agenda for our next meeting! **Sponsors** And thanks to our host, [Adaptavist](https://www.adaptavist.com/)! **Notes** * *Unfortunately, we won't have pizza at this meetup due to a gap in sponsorship. We're actively working on securing sponsors for future events.* **Agenda** **Doors Open: 5:30PM** **Event Start: 6:00PM** * 👋 **Welcome and introductions** * 🙏 **Thank you to our amazing hosts and sponsors!** 🎉 * 🎙️ **Speakers** 🎤 **Speaker #1: Curtis Collicutt** *Title: Stegalographer* *Abstract:* ***They said never write your own encryption. They didn’t say anything about steganography!*** *What if the best place to hide a secret message was in something so boring that nobody would ever look twice at it? Stegalographer is a tool that embeds data in legitimate-looking application logs by encoding information in the choices that generate the logs, rather than encrypting them. The template used, the number of trailing spaces, whether the log says 'error' or 'failure', and even the microsecond variations in timestamps can all carry hidden bits. The output isn't logs with secrets stuffed inside, but real log structure with your data silently riding along.* *This talk will explain how Stegalographer works, from analysing existing logs to extract templates (using the Drain algorithm from log analytics research), to the encoding process that turns your message into a stream of plausible entries. We will explore practical use cases such as covert channels in penetration testing, watermarking logs to trace leaks and censorship-resistant publishing disguised as 'sample data'. However, we will also be honest about the limitations: this is steganography, not encryption, and statistical analysis can potentially detect anomalies at scale. Whether you're interested in security research or information theory or privacy, or want to know more about building security tools, come and see how the most mundane part of any system can become a covert communication channel.* *We'll also touch on the experience of building security tools like this one using AI-assisted programming tools like Claude Code.* 🎤 **Speaker #2: Ads Dawson** Title: *Q&A with Ads Dawson* *Ads Dawson is an Offensive security engineer, penetration tester and red teamer with over thirteen years of experience breaking, testing, and securing applications and infrastructure across startups and large enterprises. Skilled in web application security, DevSecOps, and large-scale hybrid cloud environments, with a strong focus on offensive engineering, red team operations, and vulnerability research. Active bug bounty hunter and researcher in AI and LLM security, specializing in uncovering and mitigating attack vectors such as prompt injection, unrestricted model inference, and backdoor attacks. Experienced in leading incident response and simulating advanced adversaries to expose weaknesses before real attackers do.* *He works with organizations like OWASP and was Technical Lead for [OWASP’s Top 10 for LLM Applications](https://owasp.org/www-project-top-10-for-large-language-model-applications/assets/PDF/OWASP-Top-10-for-LLMs-v2025.pdf).* *This is your chance to ask Ads anything you want about AI and cybersecurity so come armed with your questions!* **⚡ Lightning Talks and Demos** Lightning Talks - 5 to 10 minutes long 1. Elshad Humbatli - Repo Health software project 2. **You?** \- Please reach out if you'd like to do a lightning talk or demo Please reach out to us if you'd like to present at the meetup. We are looking for people to talk about what they are working on, what they are building and learning, and are open to any level of experience and technical depth. Whether you are a beginner or an expert, we want to hear from you! We're all just out here building and learning. 👋 **See You There!** Thanks, and we look forward to seeing you at the meetup!

Bagua is a style of Kung Fu that uses circular movements and evasive stepping to overcome force with smoothness. It is similar to Tai Chi, but faster and more dynamic. We will meet at 3 pm on the grass near the front gate of Alexander Muir Memorial Garden near the corner of Yonge and Lawrence. Our focus will be on strong kung fu basics, developing body and mind and self defense. Class is $20, wear seasonable and comfortable clothing.

After just 6 weeks of 2026--are you in need of a refresher on Willpower and Procrastination?? !! I am. Learn how to focus and follow through on what matters... Personal, Work, Social, Health, Arts/Culture. **Ticket link is below**. $20-$30 option We attend 3-4 events each year with our great friends at Rotman/U of T!! ### Description **Agenda:** 5:00 pm - Check-in opens + light refreshments (coffee/tea/cookies) 5:30 pm - Presentation by author + discussion with moderated Q&A 6:30 pm - Meet-and-greet with the author + book signing **Book Synopsis:** Setting goals is easy. Finishing them is the challenge. In ***'Intentional* '--productivity expert Chris Bailey** reveals the surprising truth: **willpower isn’t enough**. The secret to accomplishing your goals lies in **being more intentional.** Bailey distills a decade of deep research on productivity to deliver a profound, practical, and counterintuitive roadmap to getting things done. Forget endless to-do lists and a never-ending workload. To reach your goals, you have to structure your daily actions around what’s most important to you—and let go of the rest. This way, getting things done becomes second nature. Integrating the science of desire, values, and procrastination with the wisdom of Buddhist monks, Bailey empowers us to build a life of true purpose and accomplishment. He offers practical strategies for following through on our goals, including how to: * Structure goals for maximum completion * Make unappealing, boring, or challenging tasks more attractive to tackle * Lower the chance of procrastinating on long-term goals * Create a framework for tracking intentions and progress * Know when a goal isn’t for you—and when it’s time to let it go Finishing what you start is more possible than you think!! **Ticket link here:** $30 Enjoy the Talk + Book + Tea/cookies $20 Enjoy the Talk + Tea/cookies https://www.rotman.utoronto.ca/news-events-and-ideas/public-events/events-listings/2026/february-2026/feb-18-do-chris-bailey/ Either way--arrive by 5pm--and enjoy something hot to drink/snack! Please note: the Rotman Author talks start at exactly 5:30pm--and finish at exactly 630pm.

**A new format: you choose who you're interested in meeting** This meetup is about getting to know new people and sharing the experience in a small group (3-6 people). *We use the LYTT platform to handle group size and balance - so you're not just hoping someone interesting shows up. To apply you will need to create an account at [lytt.me](https://lytt.me/meetup/basecamp-bouldering) \- it's free\.* **The event: Bouldering Session at Toronto's Social Climbing Gym** Basecamp is where climbing gets social. Colorful holds on textured walls, crash pads below, and a vibe that says 'yeah, you can do this.' Over 100 routes across 7,000+ square feet mean there's always something new to try. Your group meets up, grabs some chalk, and starts solving routes together. Some will fly up the wall, others will laugh at their first attempt. That's the point. Between climbs, you're swapping beta, cheering each other on, and realizing that falling is way more fun with friends watching. After, we grab drinks or food nearby. The whole experience runs about 2.5 hours. **The group: LYTT platform** LYTT forms small groups for events and activities you pick. 1\. Click 'Attend' here on Meetup\, then head to [lytt.me](https://lytt.me/meetup/basecamp-bouldering) to create a quick profile (photo, a few interests, short bio) 2\. Browse others who applied and select who you'd want to meet 3\. We form groups where the interest is mutual 4\. You get notified when your group is confirmed \- payment happens then 5\. Show up knowing your crew already picked you \- *but no one knows who picked who*, to keep mystery and low pressure Applying doesn't guarantee a spot - but we may form multiple groups or invite you to similar events with other crews. **What's included:** • Day pass with gear rental (shoes and chalk) • 90 minutes of climbing with your crew **Details:** **Cost:** $22 CAD (pay after your group is confirmed). Student/youth discounts available. **Group size:** 3-6 people **Location:** Basecamp Climbing (677 Bloor St W or 186 Spadina Ave) **Who this is for:** • 27-40ish, give or take • People who love to climb (or want to try) • Beginners welcome - no experience needed • Looking for friends, climbing buddies, or just better ways to spend an evening **Questions?** hey@lytt.me **Proceed to register here:** [https://lytt.me/meetup/basecamp-bouldering](https://lytt.me/meetup/basecamp-bouldering)

**NO PHILOSOPHY EXPERTISE REQUIRED!** **🏛️ 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://chat.whatsapp.com/KRy6VgwgGRm3hSGeYlAzDE), 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: * 19:30-19:45 - People arrive and chat, get to know each other before the official start. * 19:45-19:55 - 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. * 19:55-21:15 - 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. * 21:15-21:30 - 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. * 21:30 - 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 Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though! **💛 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 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://chat.whatsapp.com/KRy6VgwgGRm3hSGeYlAzDE). * **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. * **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 often, 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://chat.whatsapp.com/KRy6VgwgGRm3hSGeYlAzDE) 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 CLUB - Philosophy, everywhere. ✨** We started in Practical Philosophy back in 2021 and there are now 50+ chapters in over 25 countries, including Canada, Spain, Japan, Mexico and many more! 🗺️ **\*\*\*** **Join our Toronto [Whatsapp Group](https://chat.whatsapp.com/KRy6VgwgGRm3hSGeYlAzDE) 👈** **Follow us on [Instagram](https://www.instagram.com/practicalphilosophyclub/) 👈** **Our [website](https://www.practicalphilosophy.club/) 👈**

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.

For February, we'll read The Secret Agent by Joseph Conrad 304 pages First published in 1907 About the book: Mr Verloc, the secret agent, keeps a shop in London's Soho where he lives with his wife Winnie, her infirm mother, and her idiot brother, Stevie. When Verloc is reluctantly involved in an anarchist plot to blow up the Greenwich Observatory things go disastrously wrong, and what appears to be "a simple tale" proves to involve politicians, policemen, foreign diplomats, and London's fashionable society in the darkest and most surprising interrelations.

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.

As you may or may not know--I didn't until late last year--Aristotle wrote extensively on "friendship" in the Nicomachean Ethics. After 69 years the concept of friendship still creates questions and uncertainty. I had close friends in high school and for a few years after high school but our interests diverged and people moved all over the country so it was hard to maintain connections. * So if I/you haven't talked with a friend for several years, are you still friends? Are we friends who meet at Drunken Philosophy or Omnipresent Atheists? * Can you be friends with someone with whom you have virulently divergent political views? Sartre and Camus could not. * Aristotle regarded friendship as essential to a good life, not merely an added "bonus." Do you agree? * In the Nicomachean Ethics (Books VIII and IX), he claims that wealth and power are meaningless without friends. Trump has wealth and power but seems to have no real friends, but wealth and power seem meaningful to him in perverted ways. Can you have meaning in your life without friends? * Do men and women view and maintain friendships in different ways? * Aristotle categorizes friendship into three types, based on what forms the bond: * **Utility**: Based on mutual benefit, but this type is fragile and ends when the usefulness ceases. * **Pleasure**: Based on shared enjoyment (e.g., humor, hobbies). Common among youth but fades as interests change. * **Virtue (The "Complete" Friendship)**: Based on mutual respect for each other's character and goodness. You wish good for the other for their sake, not yours. * **Key Principles of "True" (Virtuous) Friendship:** * **Permanence**: Virtuous friendships last a lifetime whereas those based on utility and pleasure are fleeting. * **Reciprocity**: Requires mutual goodwill; secret or unreciprocated affection does not qualify. * **The "Second Self"**: A true friend is "another self"—their virtue helps you understand and improve yourself. * **Time and Intimacy**: Deep ("complete") friendships are few, built on time and shared experiences. * **Self-Love and Friendship:** * Good friendship starts with being a friend to yourself. * They distinguish shallow egoism (chasing honors) from real self-love (pursuing virtue). * A virtuous person’s pleasant self-company allows them to be a stable, good friend to others. * Aristotle argues that one's social circle ultimately reflects one's character—a view with striking relevance today. Well--the Drunken Philosophy social circle certainly reflects good character!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

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
