Aikido Group Class (Adults & Teens, Beginner)
**For ages 13 and above.**
Aikido is a martial art which originated in Japan with its founder, Morihei Ueshiba, in the early twentieth century and has since grown to become one of the world’s most popular martial arts.
At its most basic level, Aikido is an empty-handed system of throwing, joint-locking, striking and pinning techniques, coupled with training in the varying use of sword (bokken), staff (jo) and knife (tanto) techniques. The core principle of Aikido is not to resist the laws of nature but to harmonize without the undue application of aggressive strength. In practice, aikido techniques are applied by efficient redirection of the attacker’s power against him/her using minimal force and without being overly injurious.
The word “aikido” is formed of three kanji, namely 合 (ai) meaning joining or unifying, 気 (ki) which means spirit or energy, and 道 (dō) which is loosely interpreted as “the path” or “the way”.

Practical Philosophy Meetup - Singapore 🇸🇬
🏛️ **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/Hg7zL8ClpzM3agJCvw5HDS), 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:
* 19:00-19:15 - People arrive and chat, get to know each other before the ‘official' start.
* 19:15-19:25 - 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.
* 19:25-20:45 - 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.
* 20:45-21:00 - 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.
* 21:00 - 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 (the topic was authority) 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/Hg7zL8ClpzM3agJCvw5HDS).
* 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, but it's not required.
* 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 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/Hg7zL8ClpzM3agJCvw5HDS) 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/).

Virtual Skating Weekly Challenge!
Hi Everyone,
With Covid19 happening, there is still a limited participants for group events of up to 8 pax happening, so this just to keep the virtual skating together going.
The Challenge is to skate as much as you can during this pandemic each week. And see how we rank on leaderboard of Strava. The ranking is arranged by most distances skated each week.
Do join us through on Strava App below:
Leaderboard updates on a weekly basis and resets every week (Mon to Sun)
Join us at https://www.strava.com/clubs/freewheelers_sg
(Kindly note that with specifically the Strava app, it is unable to cater for Inline skating option, so you will have list your tracking via run or ride for your ranking to show up in leaderboard. And this is the main challenge majority of skaters will be using.)
Feel feel to contact Janice on Meetup if you need help with the apps to join us on these virtual skating challenges. You can also ask Janice for link to join a telegram group where impromptu small group skating events are frequently organized if you are looking for skating buddies.
Special Note:
Heard feedback from some Iphone users that trouble getting apps FOC. All these apps should be free. Please make sure you download the FREE VERSION. And please download the app, before you join via Challenge Links as the Challenge Links lead Iphone users to paid versions I think.
Android Phones should be automatic directed to free version.

AI Development Risk Case Studies and how Agentic AI is the future of Appsec
OWASP is ending use of Meetup, so I built an eventbrite for the event.
https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator
AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development

Azure CBUS February: Build Your Own MCP Server
### Tools in your AI's Toolbox : An introduction to MCP Servers
The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way?
This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents.
Join this session for a developer-focused introduction where you will learn how to:
Understand the core concepts of the open-source Model Context Protocol and its architecture.
Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases.
Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI.
Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem.
Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
