**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!

Standing at an elevation of 3,726m, Mt Rinjani is the second highest volcano in Indonesia, second only to Mount Kerinci on Sumatra. While the journey to the summit is challenging, it promises breathtaking views from both the crater rim and the summit. The best time to trek Mt Rinjani is during the dry season, which typically runs from April to November. Trek the awe-inspiring Mt Rinjani with us. Decide early just so you have sufficient time to condition your body for the trek!

Sign-ups *are only confirmed after contacting us and joining the WA group! \**** Gunung Berembun Jelebu (1,014m) is an interesting hike with the chance of visiting a WWII plane crash site, while hiking through a dense rainforest with waterfalls and streams, and fallen trees. There are many "Gunung Berembun" but this is the one located in Negiri Sembilan! We will be doing the classic route via Kampung Pantai. It is considered a full day hike, slightly shorter than Ophir. This is usually used as a training hike, and exposure to different elements and exploring a more raw trail, rather than a hike for the view itself. **Who is this for?** * It is most suitable for those who just want an interesting full-day hike out similar to Ophir, but less curated than the usual ones. * It serves as a good training or progressive hike for those who wish to do more hiking. Most do it as general training for hikes. * Wish to experience a more raw rainforest trail with less crowds, and different elements * Wish to do a full-day hike nearby without travelling so far * Wish to see a WWII plane crash site and wreckage * Not for those who are hunting for a beautiful viewpoint at the summit **How tough is it/How fit do I have to be?** Duration: \~5h up, and 4h down. You can u-turn at the summit instead of going to the crash site. Distance: \~7km one way, total of 14km. It is generally tropical forest trail, with some river, rope portions. However, if you have done other Malaysia hikes before like Gunung Datuk/Lambak/Ophir before, the terrain is not that much of a surprise, except it is more raw. With the presence of streams, please do expect leeches! To confirm, do RSVP and send me a whatsapp message! A Whatsapp group will be set up. Do make sure you're in the WA group if you're going. A minimum of **12 pax** is needed for this trip to go ahead. **Estimated Itinerary: (Saturday)** \~12.00 am : Meet @ Marsiling MRT 4.30 am : Breakfast 6:30 am : Reach Kampung Pantai Baru Trailhead.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.
