Hi Everyone, The next walk & talk is happening Monday 6th @ 1pm. We're meeting @ **Shrine of Remembrance "Flame"** then we'll walk to Botanic Gardens from there. For newcomers, this group is meant to help participants nurture and create a comfortable, trustworthy and safe emotional space to connect with other men, while sharing vulnerabilities about themselves. Men of all ages welcome. This will provide another great opportunity to practice being more present in the moment, authentic within ourself, while challenging our ability to break the ice with others in attendance. Let's continue practicing connecting in a deeper way with new people we meet. This group will help reinforce the benefit of showing vulnerability with others, while staying authentic to ourselves. This Sunday's group will be led by **Ra'id.** (Mindset Coach) and Co-led by **Fabien** (Group Facilitator) Looking forward to seeing you there. (message me thru meetup if needed)

Jewellers can hire a desk in our workshop to make or finish off their own pieces. This workshop is self run, you need to attend a health and safety induction before working daily unattended. Basic jewellery making tools are provided and some consumables such as flux, borax, tumbling polish, lathe polish and some drill bits. Aprons and safety glasses are provided, tie up loose hair, wear enclosed shoes. Please email claw.creative.studios@gmail.com for any questions or inquiries. Clara Carija, Director CLAW CREATIVE.

WEATHER DEPENDANT Just a random coffee meetup outside kerekere cafe in Fitzroy gardens. Come and grab a coffee and/or snack.

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)

**WALK DESCRIPTION:** This walk commemorates the tragic story from Daylesford's gold era when three small boys (aged 6, 5 and 4) wandered away from their homes in Daylesford in 1867. Despite a massive and lengthy search effort the boys were never found alive. The **Three Lost Children's walk** follows the approximate route the boys walked. The walk will take you through bush landscapes that were once active goldfields, and are now part of the Wombat State Forest and the Hepburn Regional Park. Along the walk you will see remnants of gold mines, water races and tramways. The **Easy/Medium group** will follow the entire walk, while the **Easy group** will commence about 1.5k in from the start. The walk undulates through heathy dry forest which includes Long-leaf Box, Red Box and Red Stringybark eucalypt varieties. A walking pole would be an advantage for some of the slopes that are, although short, quite steep. We hope to end the walks in time for a visit to the **award-winning craft cidery** which produces a diverse range of craft cider, made using the heritage cider apples organically grown on the farm. A cider tasting paddle may be the perfect end to a winter walk. A reminder to bring a change of footwear for the trip back, because dirty boots leave marks on the bus that our club pays to have cleaned. Please note that at this time of year there is always a possibility of encountering snakes, and appropriate leg covering is recommended. As the weather can be warm at this time of year, **please carry at least 2 litres of water.** . **DISTANCE(S):** 14km and 15.5km . **TOTAL ASCENT(S):** 440m Rise and 490m Rise . **GRADINGS:** Easy and Easy/Medium **Easy (E):** Walking mostly on tracks or in open country, with possibly some stretches of light scrub. Few hills and adequate rest stops. Distances may be up to 15km in flat open terrain but will be shorter if scrub or significant hills are involved. **Easy/Medium (E/M):** More consistent walking, mostly on tracks or in open country, but with some significant hills, probably some stretches of light scrub. Possibility of some rock hopping. Distances up to 19km but may be much shorter depending on the difficulty of the terrain. Reasonable lunch and rest stops. **.** **PLEASE NOTE:** Your RSVP on MeetUp lets us know who may be interested but does not add you to the booking list.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).
