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)

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 you to mingle before our announcements> ice breakers and games > watch party > raffles > close. We will then head to Melb Central for dinner and some quick games afterwards. 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!

[Instagram: Road Trips by The Dancing Voyager: Ron Singh](https://www.instagram.com/the_dancing_voyager_ron_trips) Sunshine forecast! Spontaneous day trip to Mount Macedon for autumn! Very short notice! These are always fun! Over 60 road trips done in 4 years! I run 3 Meetup groups (shown on my profile). This road trip is for people new to Australia who have not been to this location (International Students, Working Holiday Makers and tourists)! No evidence is required. I will trust you! **Details given below in sections: (1) Questions / (2) Road trip itinerary / (3) Payment / (4) Responsibility / (5) Breaks / (6) Weather / (7) Phone charging / (8) Contact** **\-\-\- \(1\) QUESTIONS AND ANSWERS \-\-\-** **Your questions for me:** Why is the total fee so low at $20, covering a new, large rental (SUV), fuel and driver, on something that seems really high quality and well planned, like a private tour company? Sounds too good to be true or that there is a catch. Is this genuine? **My answers to you:** Because this project is my community service to give back. I explain this further below. The low fee is just a formality to confirm your place, so that I know you are serious on attending. This is genuine. Over 60 road trips done in 4 years! I have created precious memories for many people new to Australia. Photos on Instagram link further above. **\-\-\- \(2\) ROAD TRIP SUMMARY AND ITINERARY \-\-\-** Day trip to Mount Macedon. Autumn is a truly beautiful time of the year! Mount Macedon is one of the best destinations in Victoria for autumnal bliss! **Itinerary: Organ Pipes National Park - Macedon autumn leaves - Camel's Hump - Major Mitchell Lookout - Mount Macedon Memorial Cross - Sanatorium Lake - Hanging Rock lookout - Macedon autumn leaves encore** **Meeting point: Fed Square, 8:45 am**. Back there by **6:45 pm**. Meet by the steps (main entrance, opposite the Swanston Street tram stop). **\-\-\- \(3\) PAYMENT \-\-\-** **Total fee: $20 in total (no other costs). This covers a new, large rental (SUV), fuel and driver.** **Eventbrite link for payment:** [https://mtmacedon-road-trip.eventbrite.com.au](https://mtmacedon-road-trip.eventbrite.com.au/) **Cancellations:** If I cancel the road trip for any unforeseen issues, a full refund will be given. If you cancel, there is no refund. **Why is the fee so low?** The low fee is just a formality. It might sound too good to be true or that there is a catch. There is no catch. I am simply someone who has been giving back for many years. I playfully call this project a “Melbourne travel secret”! There are people in this world who want to genuinely give back without any expectations because they are truly fulfilled and grateful for what they have. I am one of those people. This is my community service. I am not doing this for money and I never have. Money cannot buy passion. The nature of majestic Australia helped me find peace and passion and I want to give back by sharing that inspiring nature with people new to this country. If they are also inspired by that nature, then that is my reward. There is no hidden agenda in doing this project. The reason I am being quite upfront is because in this day and age, there is always a catch when people do something like this. There is none with me and I am not selling or promoting anything. I do not need anything because I have peace, passion and fulfilment. I have everything. I am truly humbled and grateful. Photos from road trips are on Instagram link below: [Instagram: Road Trips by The Dancing Voyager: Ron Singh](https://www.instagram.com/the_dancing_voyager_ron_trips) **\-\-\- \(4\) RESPONSIBILITY\, LIABILITY\, SAFETY \-\-\-** As your driver, I am responsible and liable for your safety while we are in the vehicle. Passengers are insured as per the Australian law. For times we are outside the vehicle, we then become responsible for our own liability and safety, just like every other capable adult in society. **\-\-\- \(5\) BREAKS/MEALS \-\-\-** There will be many breaks for sightseeing/walks. I will stop at places where food/snacks will be sold but you are welcome to bring your own as well. There will be a lunch break at either a cafe or takeaway shop. **\-\-\- \(6\) WEATHER AND WHAT TO WEAR \-\-\-** I plan events when weather looks good but please also see itinerary for location details and check the forecast to dress accordingly. My advice is to always be prepared! Recommend to have something to cover you if rain suddenly appears or if winds suddenly get cool. Also recommend to carry sunscreen and a hat. Please also wear good, comfortable shoes that can provide protection from water (in case there are muddy areas). You can bring many things, as the vehicle will have a lot of storage space. My road trips do not have a lot of long walks. The focus is on sightseeing, relaxing and appreciating the beauty of nature. **\-\-\- \(7\) PHONE CHARGING \-\-\-** Please charge your phone before joining. In the past, people have taken lots of videos and photos and used up their batteries! You can bring your charging cable if you want. The vehicle will have various charging ports. **\-\-\- \(8\) CONTACT \-\-\-** If you need to contact me, please reach out through Meetup, Eventbrite or Instagram. If you wanted my mobile number, please let me know.

**—— Details ——** We will meet at the starting point, take round trip around the Tan and a short stroll inside the botanical garden. BYO coffee/ water bottle. Dress for outdoor walk.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

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.

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!
