👋 Hello Grafana & Friends Singapore! This month, we are excited to partner with the MongoDB for a collaborative evening of tech! As observability and data landscapes become increasingly complex, the integration between the LGTM stack and MongoDB is more critical than ever. This month, we are bringing together engineers from both ecosystems to share implementation strategies, architectural best practices, and real-world monitoring patterns. As always, come ready to learn, connect, and exchange ideas with the community. Light bites and networking included! **Topic 1: Real-Time Observability with MongoDB and Grafana: From Logs to Dashboard** **Speaker: Piti Champeethong**, Senior Consulting Engineer, MongoDB **Session Abstract:** Learn how to integrate MongoDB Atlas with Azure Grafana to build real-time dashboards for both database performance and application data. This session covers Prometheus-based monitoring, direct querying, and Azure-native pipelines for modern observability. **Topic 2: Agentic Observability: From OTel Signals to Production Remediation with MongoDB MCP** **Speaker: Hendri Tjiptowibowo**, Senior Partner Solutions Engineer, Grafana Labs **Session Abstract:** Learn how Grafana Assistant (available on OSS) combines OpenTelemetry signals with MongoDB MCP to move from observability to action.

**DISCLAIMER: NOT FINANCIAL ADVICE** Casual run of about 3.5km - 4km. Hais, seems like there isnt a a community run group on bitcoin in Singapore. Please visit below page to sign up (Dont pangseh hor). https://www.meetup.com/runningbitcoinsg It is the only way I can filter out the bots. There is always more things to learn about Bitcoin. One of it being low time preference. The group welcomes anyone who is interested in knowing more about saving in bitcoin or simply just want to join us to have a good run.

**About the Speaker** **Simon Ritter** With over a decade of experience as Deputy CTO at Azul Systems, our speaker has helped shape the adoption of Java and JVM technologies across the global developer community. A recognized expert in Java and open source, he is passionate about advancing developer productivity, application performance, and innovation throughout the software ecosystem. **Agenda** **Keeping Your Java Hot by Solving the JVM Startup and Warmup Problem** Java bytecodes and class files deliver on the original vision of “write once, run anywhere”. Using a Just-in-Time (JIT) compiler allows JVM-based applications to compile only the code that’s used frequently and optimise it precisely for how it's used. Using techniques like speculative optimisation can often deliver better performance than static, Ahead-of-Time (AOT) compiled code. However, this flexibility and performance come at a cost. Each time the JVM starts an application, it must perform the same analysis to identify hot spots in the code and compile them. This is referred to as the application warmup time. In this session, we’ll look at several approaches to alleviating or even eliminating this problem. Specifically: · Static compilation of Java code ahead-of-time (AOT). Specifically, the Graal native image approach · Generating a JIT compiler profile of a running, warmed-up application that can be reused when the same application is restarted, eliminating the need for much of the JIT compilation. This will include details of the work of the OpenJDK Project Leyden. · Decoupling the JIT compiler from the JVM for a Cloud environment. Providing a centralised JIT-as-a-Service allows caching of compiled code and offloading the compilation work when new code must be compiled. · Creating a checkpoint of a running application. This includes all application state (heap, stack, etc.) in addition to the JIT-compiled code. Project CRaC will be used as an example. At the end of the session, you’ll be all set to keep your Java hot! **Modern Java Puzzlers** Since JDK 9, Java, as a language, has evolved faster than at any point in its 30-year history. For developers, this is great, as it means we get more new features that make our code more concise and, hopefully, easier to read and understand. All new language features also bring their quirks and possibly unseen consequences. In this fun interactive session, we’ll examine a range of recent language features and pose questions to the audience about how the code works and what it does. We’ll cover many of the new language features from recent releases, including switch expressions, sealed classes and pattern matching. We’ll even look at some curious ways special characters can be used in unexpected ways. The answers will most definitely not always be as you expect!

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
