**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!

Wrapping up the work day in the CBD? Come unwind and meet interesting people over drinks at Goodbye Alibi, right in the heart of Duxton. Every alternate month, the Singapore Entrepreneurs Network (SEN) brings its Second Wednesdays session to Duxton Road — one of Singapore's most vibrant dining and nightlife strips. It's an evening of easy conversation, no agenda, and no hard selling. With over 20,000 members and 633 events hosted since 2005, SEN is one of Singapore's longest-running entrepreneur and business networking communities. **Who shows up** The Duxton crowd is one of SEN's most eclectic. You'll find: * Professionals and executives from the CBD unwinding after work * Entrepreneurs and business owners based in or passing through the city * Expats and foreign professionals building their Singapore network * Aspiring founders scoping out the business landscape * Investors and advisors Whether you're deep into entrepreneurship or simply ambitious and curious, you'll find the conversation worthwhile. **What to expect** No speeches, no pitches, no formal programme. Just good company in a relaxed pub setting. Goodbye Alibi is a cocktail bar, come ready to drink, talk, and meet people you wouldn't normally run into. SEN events are known for being genuinely diverse and free of the polished, curated "tech founders only" atmosphere that defines most Singapore networking events. Real talk, differing opinions, and a refreshingly mixed room. **Our community standard** This community runs on one principle: honest conversation between real people doing real work. Claims are welcome. Fabrications are not. If you state credentials, be prepared to substantiate them. **Practical details** \- Venue: Goodbye Alibi\, 53A Duxton Road\, Singapore 089517 \- Nearest parking: Pinnacle@Duxton \(short walk\) \- Date: Second Wednesday of the month \(alternate months — check listing\) \- Time: 7:00 PM onwards \- Free entry **Ground rules** * Buy something at the venue. There is no entrance fee, but we are guests of Goodbye Alibi. Purchase a drink, this is a cocktail bar and that is the expectation. * No hard selling. Network freely, but do not force other attendees to sit through your pitch. * Basic decency. SEN welcomes people with differing views and backgrounds. Disagree openly but respectfully. **About SEN** In 2002, Nicholas Chan was one of eight co-founders of Project:Senso, a pioneer entrepreneur gathering in Singapore. Nicholas subsequently spun off the Singapore Entrepreneurs Network in 2005; the networking events were working, people kept coming back, and he decided they deserved a permanent home and a life of their own. Two decades on, SEN counts over 20,000 members and runs affiliated chapters in Malaysia, Myanmar, and Taiwan.

**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!

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

Over a billion documents processed. Millions of Veterans impacted. Hundreds of thousands of employee hours saved. Faster decisions. Greater accuracy. More benefits in the hands of our disabled Veterans. We created Smart Search, the world’s largest consumer of Amazon Textract, right when GenAI began reshaping what’s possible. Since then, we’ve built a suite of AI‑driven solutions that transform this data into real, measurable outcomes—accelerating benefits decisions for our Nation’s Veterans. Join us for a focused conversation on how an outcome‑driven approach to AI is helping us boost accuracy, streamline workflows, and deliver faster results for those who have served. This is a follow up to the AWS re:Invent 2023 "Intelligent Document Processing with Gen AI for Public Sector" presentation. About Speaker: Cameron Williams is a Senior Technical Project Manager and cross-functional technical leader at Booz Allen Hamilton with 15+ years of experience architecting and evolving scalable, cloud-native systems, from greenfield development to complex enterprise modernization. https://www.linkedin.com/in/cameronw711/ **THANK YOU** *Franklin University* for hosting our meetup!

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
