🎉 **Melbourne AWS User Group – March Meetup** 🎉 --- 📅 Wednesday, 25 March 📍 NAB Events Hub – 395 Bourke Street, Melbourne ⏰ Food at 6:00 pm, talks from 6:30 pm (with live stream) Join us for our March for our March meetup as we explore two important areas of modern cloud architecture: **security and resilience**. This month we’ll look at how organisations can improve least-privilege access using IAM Access Analyzer, and how to design highly resilient architectures using AWS fault isolation and multi-region patterns. This month’s lineup features: • **Hazra Ali**, a brand new **AWS Community Builder for 2026**, is presenting on how business analysis techniques can improve outcomes when using AWS IAM Access Analyzer. • **Anshika Gupta** sharing architectural principles for building resilient systems using static stability, fault isolation, and multiple AWS Regions. A huge thank you to our sponsors: 🥇 **Mantel Group – Gold Sponsor**, 🥈 **Cevo – Silver Sponsor**, 🏛 **NAB – Venue Sponsor** The event will be live-streamed on YouTube as always. *** 🗓️ **Agenda** 6:00 pm – Food & Socialising 6:30 pm – Introductions 6:40 pm – What’s New in AWS 6:55 pm – **Business Analysis in AWS IAM Access Analyzer (Level 100)**; Speaker: Hazra Ali 7:25 pm – **Reinforcing Resilience in the Real World with Static Stability, Fault Isolation and Multiple Regions (Level 200)**; Speaker: Anshika Gupta 7:55 pm – Marketplace (Who’s Hiring) 8:00 pm – Networking + Close *** 🎤 **Talk Details** **Business Analysis in AWS IAM Access Analyzer** Speaker: Hazra Ali Level: 100 Business analysis plays a crucial role in helping organisations implement change to address challenges and leverage solutions that deliver value. AWS IAM Access Analyzer helps organisations grant precise permissions as requirements evolve, guiding users toward least privilege by enabling them to set, verify, and refine permissions. In this presentation, Hazra will explore how business analysis practices can enhance the effectiveness of IAM Access Analyzer when solving real-world problems. The session will also discuss how AI can support business analysis workflows and assist in understanding the core concepts behind IAM Access Analyzer. *** **Reinforcing Resilience in the Real World with Static Stability, Fault Isolation and Multiple Regions** Speaker: Anshika Gupta Level: 200 At AWS, resilience is viewed as a continuous process, built on years of experience working with customers operating critical workloads. In this session, Anshika will explore how to design systems using AWS fault isolation boundaries and the concept of static stability to achieve predictable recovery times and high availability. You’ll learn: • How AWS Regions are designed and operated for resilience • Key architectural patterns AWS services use to maintain operations during disruptions • How static stability helps maintain availability under failure conditions • Practical architecture patterns for building multi-region resilience This session will showcase design principles, best practices, and example architectures that can help you meet your resilience requirements for mission-critical workloads. *** 🙌 **Want to Speak at a Future Meetup?** We’re always looking for new speakers and believe everyone has an interesting talk waiting to be shared. If you’d like to present at a future event, reach out at the meetup or via our website: 👉 [https://melb.awsug.org.au/speak/](https://melb.awsug.org.au/speak/)

Let's gather to learn and discuss the importance of open standards, free document formats. [https://linuxvictoria.org/events/2026-03-25_document-freedom-day/](https://linuxvictoria.org/events/2026-03-25_document-freedom-day/) ## ​Details Wednesday, 25th March 2026 6:00 PM - 8:00 PM In-person: Inspire9 AKM Building Level 1/41-43 Stewart St, Richmond VIC 3121 Online: https://electronworkshop.com.au/goto/venue ​Thank you to our venue sponsor Inspire9, Melbourne's original and top rated coworking space. ​Event hosted by Electron Workshop and Linux Victoria. ## What is Document Freedom Day ​Document Freedom Day is an annual celebration of open standards and free document formats, and we are joining this gathering, online and in-person in Melbourne (Naarm). If you've ever been locked out of a file because you didn't have the right software, or worried about your personal notes on EverNote or company notes on the cloud, this is exactly the kind of conversation worth having. Especially now, in the new era of AI, while our documents and data are more prayed on, there are more potential opportunities to store, access and hardness insight from our documents privately and securely. ​Join the meeting to listen in, to participate in the discussion or even present a lightning talk about a topic or technology you are passionate about. ### Getting to Inspire9 ​Maps Link for Inspire9: [https://maps.app.goo.gl/eRMAXpBdmG1Ece4m9](https://maps.app.goo.gl/eRMAXpBdmG1Ece4m9) ##### ​Transport ​Train station is located right next to Inspire9. Tram 70 is a short 2 minute walk. There is 2hr parking on the street but very often there are no spots. Inspire9 main entrance is wheelchair accessible. ​When arriving, head for the AKM building. ### ​Online ​Link to join: [https://electronworkshop.com.au/goto/venue](https://electronworkshop.com.au/goto/venue) We use a self-hosted Big Blue Button instance (aka BBB) for this meeting, managed by Electron Workshop and hosted by Serversaurus.

Have you ever met someone who really wants to learn guitar, but rather than have Lessons, they just watch hundreds and hundreds of YouTube videos? No order, no progressing skill and not even the same genre of music? That is how most people are approaching AI right now and Knowledge Management has something BIG to say about that. When businesses say “My system is hallucinating”, KMers hear “I fed my system a bunch of random data, why is it saying random things??”. Two words have been missing and are now taking off, in fact some are calling it a $billion industry. Context and Provenance. Come along to KMLF for a different session. We will be watching a recent discussion from one of the top voices in this field and learning and discussing what it means for us as we help guide our organisations to a better AI (and knowledge) future. Thanks again to MinterEllison, who host the amazing space we meet in each month. **Session Details:** * **Date & Time:** 6:00pm AEDST, Fourth Wednesday of each month * **Format:** Minter Ellison and on Teams * **Agenda:** * 6-6:30 pm networking * 6:30-7:45pm exploration of the topic * 7:45-8pm wrap up * 8pm dinner for those interested. KMLF has run monthly, almost uninterrupted since 1998, serving the Victorian Knowledge Management community with close ties to Change Mgt, Records Mgt, Information Governance and Academic communities.

Although many people in our Kismetrix community meet through singles events, this **Healing Circle is open to everyone and not limited to singles**. Anyone who feels drawn to an evening of reflection, awareness, and personal growth is warmly welcome. [Ticketed Event](https://www.eventbrite.com.au/e/mar-25th-the-9-senses-awakening-healing-circle-fire-ritual-tickets-1985241971177?utm-campaign=social&utm-content=attendeeshare&utm-medium=discovery&utm-term=listing&utm-source=cp&aff=ebdsshcopyurl) \-\-\-\-\-\-\-\- The 9 Senses Awakening: Healing Circle & Fire Ritual ### Healing Circle • Reflection • Release 📅 **Wednesday, 25 March 2026** 🕖 **7:00 PM – 9:30 PM** 📍 **RYVE** Level 1, 38 Shafton St, Huntingdale VIC 3166 ## A Space to Pause, Reflect, and Let Go Sometimes in life we carry things quietly inside us. Old emotions. Unspoken words. Past experiences. Stress, heartbreak, grief, or simply the weight of moving through the world. We keep going, often without giving ourselves the space to truly process what we’ve been holding. This evening is an invitation to **pause**. To breathe. To reconnect with yourself. And if you feel ready — to gently release what you no longer need to carry. The last **9 Senses Awakening Healing Circle** I hosted became one of the most beautiful and meaningful gatherings I’ve experienced. Many people shared that it gave them a rare moment to slow down, reflect, and reconnect with themselves in a deeper way. Because of that experience, I’ve felt called to create this space again. This event is **open to everyone** and **not limited to singles**. Anyone who feels drawn to a quiet evening of reflection, awareness, and personal growth is warmly welcome. ## The 9 Senses Awakening Throughout the evening we will explore awareness through **nine layers of human perception**. The physical senses • Sight • Sound • Smell • Taste • Touch The inner senses • Intuition • Emotional awareness The subtle senses • Energy (vibration and presence) • Spiritual connection Through simple guided practices, breath awareness, and mindful reflection, we reconnect with these senses — helping us return to presence and inner clarity. ## Healing Circle & Sharing This evening is held in a **healing circle**, creating a space where everyone is seen, heard, and respected. There is **no pressure to speak**. You are welcome to simply listen and be present. For those who wish to share, the circle allows space for reflection and connection with others who may be navigating their own journeys. ## Fire Ritual – Letting Go Toward the end of the evening we will take part in a **symbolic fire ritual**. Participants will be invited to write down something they are ready to release — a past story, emotional weight, fear, resentment, or something that has been quietly sitting in their hearts. As the paper burns, we symbolically allow that chapter to transform. Many people describe this moment as **deeply moving and liberating**. ## What to Expect • A calm and supportive environment • Guided sensory awareness and reflection • A healing circle and optional sharing • A symbolic fire ritual for release • A small and intimate group experience No previous experience with meditation or healing circles is required. Simply bring yourself, exactly as you are. ## Hosted by Vivienne Vu Vivienne Vu is passionate about creating spaces for reflection, emotional awareness, and authentic human connection. Her work focuses on helping people reconnect with themselves, release emotional weight, and move forward in life with greater clarity and intention.

It is **not therapy, counselling, or medical treatment**.

The discussion topic for this meetup will be identity and whether or not history is a necessary condition for consciousness as Dretske proposed. James

The optimum computing machine is a subject many of us have studied. If you were building one how would you design it? First the computer should be able to compute with perfect accuracy on any problem in the universe and produce answers which were always and invariably right. Second the computer would have to be swift, working much more quickly than the problem and process could be vocally articulated. Third the computer would have to be able to handle large numbers of variables and large numbers of problems simultaneously. Forth, the computer would have to be able to evaluate its own data and there would have to remain available within it not only a record of its former conclusions but the evaluations leading to those conclusions. Fifth, the computer would have to be served by a memory bank of nearly infinite capacity and would have to be available to the analytical portion of the computer in the smallest fractions of a second. Sixth, the computer would have to be able to rearrange former conclusions or alter them in the light of new experience. Seventh, the computer would need no exterior director, but would be entirely self determined about its programing guided only by the necessity –value of the solution which it itself would determine. Eight the computer should be self servicing and self arming against present and future damage and would be able to estimate future damage. Ninth the computer should be served by perception by which it could determine necessity –value. Tenth ,the memory bank should store perceptions as perceived ,consecutive with time received with the smallest possible time divisions between perception .It would then store in color-Visio (moving),tone audio (flowing),odor ,tactile and self sensation ,all of them cross –coordinated . Eleventh, for the purposes of solutions, it would have to be able to create new situations and imagine new perceptions hitherto not perceived and should be able to conceive these to itself in terms of tone –audio ,color-visio ,odor, tactile, and self sensation –and should be able to file anything so conceived as imagined ,labeled “memories” Twelfth, the entire machine should be portable. It might be somewhat astonishing at first to conceive such a computer .But the fact is, the machine is in existence .There are billions of them in use today and many ,many more billions have been made and used in the past . In fact you’ve got one .for we are dealing with the human mind. L.RON .HUBBARD Do you want to learn how the mind works?Then do not miss this meetup. RSVP now !!

The Filmonik Kino-Kabaret is our yearly all-you-can-film buffet of spontaneous creativity, where participants collaborate on as many short films as they can, in a shared production hub called the Kinolab, at Balam Balam Place in Brunswick. This 72+hour jam-session of filmmaking is followed by the premiere screening party of all short films that have been produced. It's fun, it's epic, it's chaotic, it's challenging, you meet heaps of new people and get attached on-the-spot to many productions just by hanging out in the hub. We're fiercely non-competitive so it's a celebration of films of all styles and scope, not a competition with creative restrictions. No teams set are to be set in advance, and writers and directors come to the Friday production meeting with a script ready to go or can improvise all weekend with the other participants. The magic should happen with the cast and crew participating and present in the hub. Short films can get written, shot and edited all in and around the hub. It's not a requirement but it's how you can learn more, challenge yourself, get help when you need it, and hop on anyone else's project to try something new. **Check out the 2025 Kino-Kabaret recap video for the vibes and venue** [https://youtu.be/w0TJ4iObWsU?si=QAm2Gbxs1HRHrJ9g](https://youtu.be/w0TJ4iObWsU?si=QAm2Gbxs1HRHrJ9g) **Registration** Tickets at [https://events.humanitix.com/filmonik-kino-kabaret-2026-a-72-hour-filmmaking-challenge](https://events.humanitix.com/filmonik-kino-kabaret-2026-a-72-hour-filmmaking-challenge) One ticket is for Directors for a spot in the screening for a film under 5 minutes and the other ticket for all other participants: cast, crew and any other film artisan participating in as many projects as they can. Every ticket includes: \- Access to our collaborative space and studio at Balam Balam Place from the evening of Friday March 27 to Monday March 30 \(Balam Balam Place opening hours apply\)\. \- Entry to the Tuesday March 31 premiere short film screening at Howler\.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

WQC has weekly Thursday night social nights at the Westerville Java Central. Come and grab a coffee and connect with the community: low stakes, chill environment, and tasty drinks. No registration is required; come as you are.

Builders, creators, architects, admins, consultants - come one, come all. This one's for you. We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform. Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live. So basically, America's Got Talent but make it ServiceNow's Got Talent. Bring a notepad if you'd like 'cause you'll definitely be learning something new. Each presenter gets 10 minutes max to wow the crowd with: • A demo • A real-world business solution • A bold idea • A UX transformation • Or a creative use of the platform Judging Criteria: 🏆 Business Value 🚀 Innovation ✨ User Experience This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value. Come learn. Come support. Come get inspired. Refreshments and bites will be provided. And maybe next time… you’ll be on stage.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.
