Innovations in Software Testing

**Special topic for this week: TODO!** Have you ever wondered what happens after you write your program in any programming language and hit "Run"? Welcome to the new group dedicated to Compiler Engineering so we can discuss language design, static analysis, VMs, and code generation. Topics related to hardware architecture and FPGA are also welcomed! **Join us weekly and learn about:** * The vision for this group. * A crash course on how to start learning compiler dev (including top book recommendations). * An open networking session for showcasing projects and finding collaborators. * Weekly topic to learn about particular aspect of programming languages or hardware **Who is this for?** * Anyone building DSLs or new languages. * Anyone curious about low-level systems and programming * Anyone hiring for compiler/toolchain roles (come pitch your jobs!). * Anyone who wants to learn more about programming languages nature! This isn't a lecture—it's a conversation. Come share your projects and get motivated! This group is not super serious, so if you want to just yap about how bad is the new C++ standard you can find some listeners here. See you!

This is at Asia Square Tower 1 of Citigroup near Downtown MRT. We'll be at the outdoor lunch tables in the common area near Asia Square Tower 1. Look for people with chess boards. We are always on, have never missed a Wednesday (except for Covid). Rain, Hail or Shine we are on (under cover). Even public holidays. Please bring a tournament sized chess board/pieces if you have one, as there is always more people than boards. This Chess meetup is for all levels of play, open to everyone free of charge regardless of race, gender or age. I will always find you an evenly matched opponent. No one should feel intimidated or embarrassed to play. It's Social Chess! Look forward to seeing you at the social chess meetup where we'll play some games, go through a famous game and for those interested, have a drink afterwards. If you're new to chess, come along and we'll have fun going through how the game works Asia Square Building Management have kindly granted permission to use their tables for this Chess Meetup on the proviso that we are orderly and we return the tables to original configurations after use (taking care not to damage the edge of tables). We have been featured in the Straits Times. http://www.straitstimes.com/singapore/after-work-chess-group-checks-all-the-right-boxes ( http://www.straitstimes.com/singapore/after-work-chess-group-checks-all-the-right-boxes ) Cheers Brad

**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!

Prostate cancer is the most common cancer among men in Singapore. Most men have no symptoms in the early stages — and by the time they do, it may already be advanced. **Early detection saves lives. And it starts with knowing your risk.** This May, take the most important step for your health and join us for a free, expert-led talk by **Dr. Lim Huat Chye Peter** — one of Singapore's most respected urologists and founder of the Society for Men's Health (Singapore). **📅 Date:** Saturday, 13 June 2026 **🕑 Time:** 1:30 PM – 4:00 PM **📍 Venue:** Farrer Park Hospital, Connexion, #16-06 (Viv Hall) **💰 Admission:** FREE **If you're a man over 40, this talk is for you.** Most men avoid talking about their health — until it's too late. Don't wait for symptoms. Prostate cancer is highly treatable when caught early, but the window matters. This is your chance to get straight-talking, expert guidance in a relaxed, open setting where all questions are welcome. **What you'll learn:** * What prostate cancer is and how it develops silently * Who is at risk — and why men over 40 need to act now * When and how to get screened, and what tests to expect * Treatment options and the latest advances in urological care * How to have the conversation with your doctor — and what questions to ask Come alone, or bring a father, brother, husband, or friend.

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

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###
