⚠️ **REGISTRATION IS REQUIRED VIA [LUMA](https://luma.com/7adqd4e9)** ⚠️ **ABSTRACT** SHELLgym is the regular cybersecurity workout you have been looking for! Whether you're just starting out and need some exercises, studying for a cert (hint: OSCP), looking at CTF challenges, or developing something cybersecurity-related (maybe your own automated tools?), SHELLgym aims to help you progress in picking up practical cybersecurity knowledge and skills. Come and go as you please, work on your own stuff with like-minded individuals, or just have fun during the workout! **AGENDA** Getting and using shells. Finally, a topic in SHELLgym that covers shells! For this session, we'll talk about remote access, from exploits versus payloads, to simple persistency. Then, we'll do some triaging and threat hunting to detect such shells in our environment. The session will roughly follow this sequence: 1\. Remote access: bind/reverse shells 2\. A simple\, traditional killchain from exploit to payload to persistency 3\. Getting inspired by MITRE TTPs 4\. Threat hunting **⚠️ NOTE** Requirements: a computer, so that you can connect to the network, administer your shells, and enjoy a more interactive hands-on experience. **VIRTUAL SHELLgyms in APRIL** (by request) Hosted on Discord, do approach KK or the Div0 Crew for access ! **TRAINER** **KK "Jim" Tan — Founder, counterShell** As a mid-careerist convert to cybersecurity, **Jim** picked up his practical skills through getting OSCP certified and by participating in a variety of CTFs. In his career at CSIT, he performed a variety of red-teaming and vulnerability research roles and established the Cyber Training School at CSIT as the Lead Instructor. Besides the OSCP certification, Jim is also OSCE and OSEE certified, and has a Bachelor's degree in Social Science (Psychology). He now sees psychology as a field of study where you fuzz humans until they produce unexpected behaviour. **SPONSORS** * VENUE SPONSOR: [CyberSG TIG Collaboration Centre](https://www.linkedin.com/company/cybersg-tig-collaboration-centre) **IMPORTANT NOTICES** * Code of Conduct: [https://www.div0.sg/code-of-conduct](https://www.div0.sg/code-of-conduct) * Terms of Use & Disclaimer Notice: [https://www.div0.sg/terms-of-use-disclaimer-notice](https://www.div0.sg/terms-of-use-disclaimer-notice)

🏛️ **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/). **PRACTICAL PHILOSOPHY - Making Philosophy Available To All.** ✨ Practical Philosophy hosts weekly, in-person meetups in over 20 countries, including Canada, Spain, Japan, Mexico and many more! 🗺️ \*\*\* Join our [Whatsapp group](https://chat.whatsapp.com/Hg7zL8ClpzM3agJCvw5HDS) 👈 Follow us on [Instagram](www.instagram.com/practicalphilosophyclub/) 👈 Our [website](https://www.practicalphilosophy.club/) 👈

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites. Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires. **The breakdown of the four-class series is as follows:** **Class 1: Introduction to Web Structure and Basic HTML5** This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document. * **Topics**: * **Web Architecture Overview**: How browsers, servers, and web pages interact. * **HTML Fundamentals**: Understanding elements, tags, and attributes. * **Basic Document Structure**: Using !DOCTYPE html, html, head, and body. * **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br). * **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a). * **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website. **Class 2: Semantic HTML5 and Multimedia Integration** Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization. It also covers adding images and multimedia. * **Topics**: * **Semantic Elements**: Understanding and implementing elements like header, footer, nav, section, and article. * **Images**: Adding images using the img tag and attributes like src, alt, width, and height. * **Multimedia**: Embedding audio and video content using the audio and video tags. * **File and Folder Structure**: Best practices for organizing project files and managing file paths. * **Activity**: Students refactor their Class 1 project to use a proper semantic layout and add an image and a link to a video file. **Class 3: Forms and User Input** This session is dedicated to building interactive HTML5 forms, which are essential for capturing user data and input. * **Topics**: * **Form Basics**: Using the form element, action and method attributes. * **Input Types**: Exploring various input types (e.g., text, password, checkbox, radio, date, submit). * **Form Elements**: Utilizing label, textarea, select, option, and button. * **Client-side Validation**: Implementing HTML5 validation attributes like required, minlength, and pattern. * **Activity**: Students build a complete contact form with different input fields, radio buttons, and basic HTML5 validation. **Class 4: Introduction to CSS3 and Basic Styling** The final class introduces Cascading Style Sheets (CSS) to style the HTML content and make the web pages visually appealing and accessible. * **Topics**: * **CSS Fundamentals**: The role of CSS, selectors, properties, and values. * **Integrating CSS**: Using inline, internal, and external style sheets. * **The Box Model**: Understanding margin, padding, border, and content for basic layout. * **Basic Styling**: Changing colors, fonts, and text alignment. * **Accessibility Basics**: Identifying principles of web design usability and accessibility, including ARIA labels. * **Activity**: Students apply an external CSS file to their Class 3 form project to style the layout, colors, and fonts, culminating in a well-structured and styled webpage.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!
