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)

**Outer Eastern Suburbs Melbourne Atheists Meetup** From 1pm at Mooroolbark Maccas. 18 Manchester Road, Mooroolbark. Look for the Atheist t-shirts/windcheaters or message/call 0438 043 050. The Outer Eastern Atheists are partnering with the *Maroondah & Yarra Ranges Atheists*; the *Melbourne Eastern Hills Skeptics* and the *Knox Atheists* for in-person meetings in Mooroolbark. The location is on the border of Maroondah and Yarra Ranges. The location will also be convenient to some in Manningham and Whitehorse and a bit further away is Monash and Nillumbik. It is near the Mooroolbark railway station therefore accessible by trains on the Lilydale line. We meet every second and fourth Thursdays. **We will be socialising with activism for those who want it.** **Sometimes we will have a special guest to speak.** For those who can't make it for lunch, we can organise evening and weekend events if you tell me (Andrew Rawlings) what you want, where and when. A day snow trip is being planned for next winter, During the year we will also join in some Melbourne-wide events like the Progressive Atheists Anniversary Lunch (January), Charles Darwin Day BBQ (February), Atheist Day and Nowruz BBQ (March), Remembering Atheists Day (April), Yalda/Sumner Solstice/ChristMyth BBQ (December) and other ad hoc events. **You are invited and welcome.** **Please share the invitation with other Atheists.** Regards, ***Andrew*** Andrew Rawlings

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/)

We encourage our members to support anime artists and producers by purchasing their movies or any full series should they wish to watch the endings. **Some insight for newer members:** It's a natural process to feel a little anxious attending a large event you have never experienced before. During sign ins our hosting team will naturally be busy however our meet & greet volunteers will do their best to say 'Hello' to everyone and perhaps connect you to others. If for some reason this does not happen (because it's really busy), don't fret! Our ice breaker games are designed to help everyone bond over a shared experience. You should expect adults having fun and letting lose whilst being challenged to push some comfort zones which we invite you to do as well! The games are suppose to be silly to help people come out of comfort zones and get to know someone new. We will then take a break to watch anime and we really do encourage you to stay for games after dinner which is when our team gets a breather and a good chance to get to know our newer members better in a quieter setting! We have witnessed many wonderful long term friendships formed at MAC amongst our members - We do hope you join us! **THANK YOU FOR YOUR DONATIONS** A big thank you to everyone who RSVPs - This money helps with the club's upkeep and hiring of the venue!

Your ability to work and live with others is crucial to your survival. To survive well one needs ability. Today meetup topic: Creating and Improving Ability And if you think you already have all the ability one needs to survive well then it is important for you to learn how to KEEP IT FROM GOING AWAY. Attend our Free Meetup! Definition for Ability: One's power to observe, to make decisions and to act. A man is as free, as well-off, as he is able. A family is as happy as it has ability. A business is as well-off as it has able people in it. A country is as well-off as it has able workers, foremen and executives. At today's meetup learn what constitutes ability and more importantly how to develop and improve it so that it does not go away. Fact's are that one's ability is never the same. It either goes up or it will go down. Your natural as well as learned abilities are constantly subject to many of life's pressures. One can therefore simply not rest on one's laurels regarding your current abilities and simply assume they will always be available for use. The time to protect and enhance ability is when you are still able. Any loss of ability will result in less confidence followed by problems resulting in unhappiness. This is called the dwindling spiral. Not just for you, it will impact all others you associate with as well. Today's topic applies to all aspects of life but will focus on how your abilities or lack of abilities or a sudden or gradual lowering of ability relates to work and family life. On your arrival you will be asked to complete a Oxford Personality Test. From this you will learn what ability it is that needs attention and improving. Whilst at our meetup you will also learn about some of the different technologies are that you find here which actively create, protect or enhance ability in key areas of life. The world cries out for better people (More Able People) that will lead happier life's with better better jobs, stronger families as well as community and businesses groups. Get The Know-How for life, attend our meetup or ask me for a time that is better suited to your schedule.

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change.
