**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!

**For ages 17 and above.** The Quickstep was developed in the 1920s in suburban New York, and was greatly influenced by the Charleston fever of 1925. Seen as a light and fast-paced dance with smooth glides and chasses, the Quickstep is a dance with basic steps that are easy to learn for beginners, and provides an impressive expression of rhythm for advanced dancers. The Quickstep is certainly a fun dance for those who want to learn Ballroom dancing and also keep in shape. ### **Address** 795, North Bridge Rd, #02-01 797, 198763 ### **Schedule** Fridays 9PM - 10PM ### **Booking Information** * Please contact **98225900** to find out how to book this class. * The instructor will reach out to you once you've booked the class.

Women Devs Singapore is excited to collaborate with Zenika for an insightful evening exploring the intersection of leadership, product thinking, and AI with our guest speaker, Jolyn Chuah. As AI becomes part of everyday work, the questions that matter most are still deeply human: ✨ Are we creating environments where people can do their best work? ✨ Are we solving real problems or simply shipping solutions? ✨ Are we approaching change with curiosity rather than fear? In this session, Jolyn will share practical frameworks and real-world experiences from product management, systems thinking, and data analytics to help leaders and builders navigate an increasingly AI-driven landscape while keeping people at the centre. You'll leave with three powerful questions to reflect on: 🔹 Lead — Am I creating conditions where people can do their best work? 🔹 Build — Am I solving real problems or just shipping solutions? 🔹 Adapt — Am I engaging with change with curiosity or with fear? Whether you're a developer, product professional, team lead, or simply curious about the future of work, this conversation is for you. 📅 Join us for an evening of honest insights, practical takeaways, and meaningful discussions.

We've opened this up for those who were not lucky enough to get a spot for our 1st meet and greet! Come get to know fellow Nudgers and BeSci enthusiasts! We'll be having dinner at 49 Seats Holland Village.

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.

**Abstract:** Motivated by the challenges of detecting extremely rare failures in sophisticated circuit design specifications, we study the problem of efficiently identifying multiple disjoint regions of interest (ROIs) — regions of a continuous, high-dimensional parameter space where a complex, expensive-to-evaluate target function falls below or above a pre-specified threshold. We reframe this problem as a Bayesian sequential decision-making problem and, more broadly, as an instance of strategic agent behavior in continuous spaces: an agent that must allocate a hard evaluation budget intelligently, updating its belief about the unknown function after each observation and choosing the next query to maximize coverage of all disjoint failure regions rather than convergence to a single optimum. This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1](https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1) Meeting ID: 893 7923 0295 Passcode: 5t5WYn **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W.
