**Gain The Confidence to Be Unstoppable! Free Class.** How to Achieve Self Confidence! Without question, self confidence is the key to success. It determines how many of your goals you achieve in life and has an enormous impact on your happiness. It affects how people perceive you, your career achievements, your ability to take risks or try new endeavours, as well as your overall attitude toward yourself and others. Self Confidence is something most people would like to have more of, but aren't sure how to get. Did you ever feel more certain of yourself in the past? Would you like to raise your self confidence ? To increase self confidence, you have to understand what reduces it. If you know why this happens you can reverse the situation and rebuild your self esteem. Self Confidence is self-determinism. One's belief in one's ability to determine his own course. As long as one has that, he's go the universe in his pocket. - L. Ron Hubbard. This day you are able to Learn a few things about: • The true source of security in life. • How self-confidence, self respect and self trust interrelate, and what you can do to rehabilitate them. • The exact steps to become more competent in whatever you do.

Hello everyone! Join us for an Apache Kafka® x Apache Flink® meetup on **Apr 9th from 5:30pm**, in Melbourne! The address, agenda, and speaker information can be found below. See you there! **📍Venue**: 394 High Street Northcote, Victoria 3070 \*\*\* **🗓 Agenda:** * 5:30pm: Doors open * 5:30pm - 6:00pm: Pizza, Drinks, and Networking * 6:00pm - 6:30pm: Chad Harris, Solutions Architect, Factor House * 6:30pm - 7:00pm: Stephen Ermann, Senior Customer Success Technical Architect * 7:00pm - 7:30pm: Additional Networking \*\*\* **💡 Speaker:** Chad Harris, Solutions Architect, Factor House **Talk:** Things that go bump in the night: Kafka Operational Issues and How to Survive Them **Abstract:** Most Kafka talks focus on how things should work—this one is about what actually happens in production. We’ll walk through real-world operational issues encountered with Apache Kafka and its clients, from subtle misconfigurations to full “why is everything on fire?” moments. Along the way, we’ll break down how to identify what’s going wrong, which signals actually matter, and how to approach debugging when the system doesn’t behave the way you expect. This talk will also touch on observability, common failure patterns, and practical mitigation strategies you can apply immediately. Expect a mix of technical deep dives, debugging workflows, and a few war stories (including some questionable decisions and log-staring sessions). If you’ve ever wondered whether it’s just you? It's not! **Bio:** Chad Harris is a streaming data specialist and Solutions Architect at Factor House, where he helps organisations design, scale, and operate Apache Kafka platforms using industry-leading tooling. With experience scaling Kafka across organisations ranging from small startups to some of Silicon Valley's largest companies, Chad has been working with Kafka since its early days. He brings deep expertise across both real-time streaming and data-at-rest systems, with a strong focus on practical, production-ready architectures. \-\-\-\-\- **💡 Speaker:** Stephen Ermann, Senior Customer Success Technical Architect **Talk:** From Lag to Smooth Sailing: How Queues for Kafka (KIP-932) Fix Slow Consumers **Abstract:** Slow or bursty consumers are one of the most common reasons Kafka applications end up fighting lag, over-provisioning, and operational fire drills. Traditional Kafka consumer groups work brilliantly for high-throughput stream processing, but they can make it hard to serve heterogeneous consumers, apply backpressure cleanly, or guarantee fair access when some consumers fall behind. In this talk, we’ll explore **Queues for Kafka**, the new KIP-932 feature that introduces native queue semantics on top of Kafka’s battle-tested log foundation. We’ll look at how queues decouple producer and consumer throughput, isolate slow consumers without penalising fast ones, and provide more predictable delivery and scaling behaviour for “task” and “work queue” style workloads. You’ll walk away with: * A clear mental model of how Kafka queues differ from topics and consumer groups * Concrete design patterns for handling slow and spiky consumers * Migration tips for evolving existing Kafka-based services to use queues safely If you’ve ever stared at a lag graph wondering whether to add more consumers, more partitions, or more coffee, this session will show you a cleaner path to smooth sailing with Kafka. **Bio:** Stephen Ermann is a **Senior Customer Success Technical Architect at Confluent**, working with leading financial institutions across APAC to design and operate mission-critical, real-time data platforms. With deep experience in **Apache Kafka**, **Confluent Cloud and Platform**, and surrounding ecosystems like **Kafka Connect** and **Apache Flink**, Stephen helps customers solve hard problems around scalability, reliability, and security in production. They are particularly focused on **RBAC, OAuth, mTLS, and container image security**, as well as emerging **agentic AI** patterns built on streaming data. Outside day-to-day architecture work, Stephen regularly shares practical patterns and lessons learned at meetups and user groups across the region. \*\*\* If you would like to speak or host our next event please let us know! community@[confluent.io](http://confluent.io/)

Hi Gophers! Join us this April for an evening of Go talks exploring real-world systems, from building a BitTorrent client to running Go on legacy architectures. We are looking forward to connecting with you. * **Agenda** **6:00pm — Food & Networking** **6:30pm — Intro + Go News** **6:45pm — Talks** **8.00pm — Wrap up then head out for kick ons** **🎤 Tom Clancy** **Building a BitTorrent client in Go** BitTorrent, first released in 2001 is a peer-to-peer protocol for file sharing. Its decentralised approach, where pieces of files are exchanged with peers (rather than a central server), is a natural fit for Go's concurrency model. This talk looks at the inner workings of the protocol, how to build your own client, and concurrency patterns for performance. Bio: Tom is a Software Engineer at Megaport, working on their edge networking functions platform (written in Go). **🎤 Sam Hobson** **Compiling Go for Ancient Architectures** Some customers approached Knocknoc asking if we can get our Go agent to run on their old HPUX PA-RISC and Solaris SPARC machines, both unsupported by Go, and we took on the challenge of finding a way to make it work Bio: "I'm Sam, I'm a software engineer of a couple of years working at a startup called Knocknoc on Just-in-time network layer access control software. Please come talk to me about cool stuff you're working on!" * **Interested in speaking at an upcoming event?** We will aim to have a mix of short (\~10min) and in-depth (20-30min) talks. If you’re keen to give a talk on a topic, share a project, or idea, please let us know [bit.ly/GolangMelbourneSpeakersForm](https://bit.ly/GolangMelbourneSpeakersForm)

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
