🎬 Online "A Java 8 lambda and JobRunr is all you need for distributed job scheduling!" by CoffeeJug!
📅 Date: 12th June (Thursday)⏰ Time: 7:00 PM - 8:00 PM EET🎤 Speaker: Ronald Dehuysser, CEO (Chief Everything Officer ☺️) @ JobRunr🆓 Entrance is FREE! (Pre-registration required) https://forms.gle/71MmyC1ub9Dx4Gj38More details:Do you need to perform some CPU heavy tasks? Or some work that requires a lot of I/O? Or do you just need to run or schedule some background jobs without blocking the rest of your system? I often see teams building a scheduling solution themselves, severely underestimating the complexity of running jobs asynchronously. A costly endeavour, especially with a simple, free and open-source solution readily available.During this humoristic session, I will introduce you to JobRunr: the ultimate library for background processing in Java. By transforming Java 8 lambdas into distributed background tasks, JobRunr allows you to run any job at anytime and on any JVM. We’ll go over the different functionalities like job persistence, automatic retries, scaling up (hello k8s) and the embedded dashboard to give you a good grasp of the possibilities. Oh, and did you know it also works on GraalVM?After this session, you’ll have a good idea of what JobRunr is, how it does it's magic and how it will allow you to focus on delivering value to your end users instead of implementing scheduling over and over again.#CoffeeJUG #JUG #JobRunrCoffeeJug - monthly events for #Java professional (#javausergroup).

🎬 Online "OOP vs. Data Oriented Programming: Which One to Choose?" by CoffeeJug! ☕️
📅 Date: 25 Sep (Thursday)⏰ Time: 7:00 PM - 8:30 PM EET🎤 Speaker: Venkat Subramaniam, Founder @ Agile Developer, Inc.🆓 Entrance is FREE! (Pre-registration required) https://forms.gle/fKHhrJe5x4cfXx5j7More details:We rely heavily on polymorphism when programming with the object-oriented paradigm. That has served us really well, especially to create extensible code. However, like any tool and technique, there are times when that may not be the right choice. Java now provides an alternative that is useful in those select situations—the data-oriented programming. In this presentation we will start with an example where the highly useful object hierarchy and polymorphism appears as a misfit and discuss how data-oriented programming solves the problem more elegantly. Get a good understanding of when to use each one of these and how to intermix them in your applications.#CoffeeJUG #Java #OOP
