AEM has a vast infrastructure, and it requires time to hold expertise on it. Every expert was once a beginner, so you are never too late to start and have fun on AEM. In this blog, we will focus on the developers’ perspective of AEM and how one can start as an AEM developer. We […]

Completable-Future is used for asynchronous programming in Java. Asynchronous programming means writing non-blocking code by running a task on a separate thread than the main application thread and notifying the main thread about its progress, completion or failure. This way, main thread does not block/wait for the completion of the task and it can execute other tasks […]

Introduction to Spring Framework for Java This article walks through the basics of using Spring Framework for Java. From a very, very high level point of view, Spring Framework infers a program’s runtime behavior from labels that the programmer attaches to pieces of code.

When you work with extensive data, there is no guarantee that inputs will be coming from another java-based application or even database. In fact, […]

The first thing I learned as an AEM developer was mvn clean install -P autoInstallBundle. The second thing was how to debug a remote Java process. The first allowed me to deploy updates I made to the bundle. The second allowed me to step through and debug the code. This was the normal cadence. Since […]

In a comment on my previous post Apache Sling JVM Performance, Gil Tene made an insightful comment about the potential possibility of performance impact from speed from the underlying environment or other tests. To accommodate for this possibility, I re-ran the tests inside a loop, randomizing order of the JVM execution for each iteration 25 times. […]

With the recent proliferation of Java Virtual Machine (JVM) implementations, it’s difficult to know which implementation is the best for your use case. While proprietary vendors generally prefer Oracle Java, there are several open source options with different approaches and capabilities.  Given how the implementations vary in some underlying technical specifics, the “correct” JVM implementation […]

Java has been the go-to coding language for decades, but as advancements in big data processing continue to emerge, Java developers are forced to learn new skills and explore additional programming languages. That is especially true when developers start working with massive amounts of data and need more elegant solutions, faster. As an alternative to […]
