Join this year's "deep dive” conference for experienced developers organized by ITkonekt.👇 Instead of standard conference talks, this program will consist of mostly 2 hour deep dives, which are meant for deeper practical learning. The conference contains of two simultaneous parts - Classroom 1 (Java) and Classroom 2 (.NET) on which you will have a chance to learn from the biggest experts in the industry. Sounds interesting? We are giving away TWO TICKETS for Java Classroom 1. The only thing you need to do is comment why you deserve the tickets and who is going with you! The most creative comment wins (decided by our developers)! 😄 📅 May 17th, 📍 Sava Centar, first floor. You can find the full program on the link - https://itkonekt.com/

it is unbelievable that it's already been a month since Devoxx UK 2024 and it is a good time to reflect on it. It was my 6th (or 7th?) When I was there helping as a volunteer and as always I had an incredible time, being part of the great team, who delivers the best possible #conference for the global #developer #community. This year though, I was there in the 2nd role too. As a presenter, for the 1st time at any conference. My previous experience was limited to giving talks at my workplace, or local community events such as London Java Community #jug. These attempts are important for me, as they are a confirmation that public speaking is something I want to do as a professional and that I like to share my knowledge and help others by talking about my experiences. But speaking at Devoxx is a much higher level. It's like you've just learnt how to walk and decided to run a marathon, even if it was only a 15-minute presentation. The worst was the stress before. It was building up in weeks before the conference, with a culmination minutes before my talk. I even had thoughts that maybe I should find some excuse to cancel my presentation 😅. And here I am, standing in the room, with the flashlight, sharing my thoughts about the topic close to my ❤️. How important is it to actively participate in local communities? Why is it that communities need you, normal folks, who think they have nothing special to contribute? Was it perfect? No. Did I like the experience? Yes! Even though I still have a long way before I reach the level of my colleagues Simon Maple, Steve Poole and many others who are my inspiration. But they have started from the same level as me, right?

This year, at JAX London 2024 conference, our architect Ram Lakshmanan was invited to talk on the topic: “KNOWN JAVA APIS, UNKNOWN PERFORMANCE IMPACT”. In our everyday Java programming, we rely on familiar APIs without fully realizing their hidden performance impacts. This session aims to unveil the concealed performance aspects of common Java APIs and shed light on how they can influence your application's performance. Join us to explore the unnoticed performance effects of these APIs and learn strategies to mitigate their impact. Whether you're a seasoned developer or new to Java, this paper equips you with essential knowledge to optimize your applications. Here is the deck shared in the conference:

Find out how Java's Garbage Collection has progressed since JDK. Watch this session by Stefan Johansson from Devoxx UK to learn the basics, explore different GC algorithms and see how the right choice can boost your service performance. View talk @ devoxx.co.uk/talk?id=11173

CIJUG March Meetup is TONIGHT at 5:30pm! Join virtually for a discussion by Ryan Bergman from John Deere on TDD in Modern Java, and why it is needed more than ever. This talk will cover the progression of TDD, BDD, and mocking strategies in modern Java, and detail how TDD makes system design simpler, safer, and easier to manage. Learn how to avoid the pitfalls that lead to big balls of mud and tests that make changing production code painful. Details here: https://lnkd.in/gV7wVSN3

I’ll be talking about balancing software performance and complexity, techniques and tools to find and solve performance problems, and how hashing strings got a lot faster in Java 21 at QCon London on April 8th.

In this session, Roy van Rijn pushes Java to its limits! Discover how he managed to process one billion rows of weather data in under 2 seconds. This is a deep dive into parallelism, memory mapped files, Graal native compilation, and more. View talk @ devoxx.co.uk/talk?id=49502

Do you consider yourself both a coffee aficionado and productivity enthusiast? While a piping hot serving of java is known for its energy-boosting magic, it’s not always the most reliable source of productivity for the long-term. Luckily, there’s a method that's as satisfying as your favorite cup of joe: the MOCHA Method. Grab your favorite mug, brew yourself a fresh pot, and explore the ins and outs of the MOCHA Method: https://hubs.la/Q02pFPnb0
