**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!

🏛️ **WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 📓 **HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/Dsjl0cwLVxR4tw1jTC1Osx?mode=gi_t), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 19:00-19:15 - People arrive and chat, get to know each other before the ‘official' start. * 19:15-19:25 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 19:25-20:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 20:45-21:00 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo. * 21:00 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other. **🧧PRICING?** Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though! 💛 **WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * ​What will we talk about? What's the topic? ​The topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/Dsjl0cwLVxR4tw1jTC1Osx?mode=gi_t). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/Dsjl0cwLVxR4tw1jTC1Osx?mode=gi_t) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group!

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
