Too many kids as well as teenagers and adults have problems with study. Today's meetup will inform you about the basics in STUDY TECHNOLOGY that provides an understanding of the basics of learning and supplies exact ways to overcome all the pitfalls one can encounter during study. This is applicable to young children, teenagers (or their parents that are trying to help them) and adults alike. Study Technology shows how one studies in order to comprehend a subject so one can apply it. Laws on which learning is based and workable methods have also been discovered for anyone to apply for themselves or when teaching others. Too many students graduate from school and college unable to put to use what they’ve learned in school. It’s not that they’re stupid or that their teachers didn’t know how to teach. More than likely it traces back to the one thing missing from most educations—learning how to learn in the first place. We all went to school, yet isn’t it odd that no one taught us how to study? The information presented at this meetup can help anyone improve others or his own ability to learn. It is a practical tool that parents and teachers alike can use to enhance a child's study performance. You’ll learn the barriers that lie between your own or a child's education. And you will very quickly learn how to overcome them. This technology will enable you or a child to pursue any subject with skill and confidence. Teachers who have "hard to handle/distributive " or slow learners in class will absolutely love the amazing turn around most often seen in improved behaviour and student performance in class. If you or your child has difficulties at school (or learning new things at work or online) than this meetup is important to you. If you can not make it to our meetup than contact the organizer and arrange it to suit your time. This technology can if one was to live far away be taught online. (extension course) You may offcourse also opt to have this technology taught to your own child by experienced volunteeer staff or learn about this yourself and transfer this knowledge to those you want to have better grades. Yes it is possible to improve anyone's study performance. All it takes is just 5 steps. See you at this meetup. Pam

**Your workshop:** Product managers are often working from incomplete information - a customer or leader asks for a change, but the real need underneath it isn't always clear. And even when ideas are strong and teams invest real effort, there's no guarantee that what gets shipped will actually change behaviour or become part of everyday practice. This workshop is an opportunity to slow down for an hour and explore how behavioural and implementation science can help design the human side of your work. From understanding what people are really trying to do, through to validating ideas, bringing your team along, and measuring impact that goes beyond the pilot phase. We'll work through some practical frameworks and implementation science strategies for influencing change. You'll also have time to apply these to something from your own work and share with the group. Come ready to think, discuss, and leave with something you can actually use. Doors: 6pm Start: 630pm **Our workshop lead:** [Dr. Alex Waddell](https://www.linkedin.com/in/alexandrawaddell/) is a behavioural and implementation scientist and the founder of CoFormed, a consultancy that partners with expert teams to turn excellent ideas into real-world impact. Alex brings expertise across behavioural science, implementation science, and service design to help teams design the human side of change by understanding what drives behaviour, what gets in the way, and what makes something part of everyday practice. **Our Host:** Zendesk https://www.zendesk.com

With our next EUXMELB meetup on the 28th of May, I'm excited to announce that **Natalie Ellis, Partner and COO at The Product Bus, will be presenting 'Your skills *are* the product'.** According to Harvard Business School 95% of new products launched every year *fail.* Natalie is here to argue that the reason for these failures isn't a lack of talent or tools, but because no one stops to ask whether the market actually wants or needs these things before shipping them. Online rhetoric discusses how AI is transforming the design, product and engineering worlds, but from her perspective, Natalie believes AI is actively multiplying the rate of failure because it's now possible to build something no-one asked for in an hour from your Mac mini. Natalie is here to tell us why evidence-based, commercially focused product thinking is more critical than ever for countering the wasted time and resources spent shipping products no one asked for. She will explain why the skills designers and researchers already possess are the real commercial asset and how people in these roles can start treating them as such. Natalie has spent her career turning consumer insights into product and commercial decisions across startups, enterprise, government digital services and institutional programs. Following a decade rising through a global market research agency, she jumped ship to an early-stage market research startup before spending several years as a product strategist designing and delivering national digital health services. As Partner & COO at The Product Bus she is passionate about helping founders, teams and businesses make real progress through evidence based decisions and passionate about helping them stress-test ideas before they commit to building. She escaped the city for rural life in the Alpine Shire several years ago where she has become an accidental pumpkin farmer and enjoys crocheting while watching crime drama. Event will start at 5:30pm with Pizza, Drinks and networking with the talk starting at 6pm. We are at Stone and Chalk in the space just past where you sign in. This event is sponsored by [askable](https://www.askable.com/) ([https://www.askable.com/](https://www.askable.com/)) and Experience Design "UX" Agency [blueegg](http://www.blueegg.com.au/) ([http://www.blueegg.com.au/](http://www.blueegg.com.au/))

Live event streams are handled using KQL/Eventhouse, enabling low‑latency dashboards and operational insights with minimal processing overhead. In parallel, near real‑time and batch data is processed using governed, lightweight Fabric patterns designed for efficiency and scale. The outcome is a single, capacity‑aware Fabric platform where real‑time and analytical workloads coexist cleanly, with Power BI as the unified consumption layer. **About The Speaker** Arjun Shankar has over a decade of experience turning data challenges into scalable, cloud-first platforms that drive real business decisions. He has worked across banking, finance, transport, insurance, and energy, specialising in the Azure stack: Synapse, Data Factory, Databricks, PySpark, and Fabric. From reducing platform costs, to accelerating delivery, and putting self-service analytics in the hands of the people who need it. Outside work, he's usually out on a trail, training for his next marathon, or keeping up with two young boys. We’re excited to bring the Data Engineering Melbourne Meetup group together for an evening with Arjun and his insights!

**The Blockchain Backdoor: How Attackers Used ENS to Subvert the WordPress Supply Chain** - **Aadam Shaik and Rohit Hande** What happens when the "Kill Switch" is decentralized? In early 2026, a sophisticated threat actor acquired a portfolio of over 30 WordPress plugins, including the popular "Accordion and Accordion Slider," to execute a massive supply chain attack. While the initial vector was a traditional acquisition-turned-backdoor, the true innovation lay in the Command & Control (C2) infrastructure. This talk deconstructs how attackers utilized the Ethereum Name Service (ENS) to create unblockable, dynamic C2 resolution. By querying public Ethereum RPC endpoints directly from server-side PHP, the malware bypassed traditional DNS-based security perimeters and neutralized standard domain takedown strategies. **Location** Room 080.02.002 at RMIT (Building 80) - 445 Swanston St, Melbourne **Discord** [Discord Event Info](https://discord.com/events/1347056412529791047/1477841544907325591) **Streaming** If you can't attend the event in person the talks will be streamed in the "ruxmon-stream" voice channel in the Ruxcon Discord in the day of the event!
