A software engineer's journey
Some time ago I started learning Cloud infrastructure fundamentals and integrated a few Cloud services in my development graduation work. At some point I thought it would be fun to deploy my application, trying the different Cloud providers to see if one is more fitted for Java applications (one would think Oracle Cloud is more...

Cloud deployment is slowly becoming a new normal, and several studies already showed that there is a dramatic shortage in Cloud-skilled engineers. That's a very good reason already to start learning Cloud concepts, but to my point of view there's even more to it. How I started learning Cloud for free During the first months...

A lot of friends would think that, due to the shortage in developers on the labor market, they would get hired as soon as they graduated, just by being there. The truth is, although companies are fighting to find developers, they're above all fighting to find good developers. I'm not talking about those companies dreaming... Continue Reading →

One of the goals UI-wise was to implement a dark theme switcher to my web app. Although theme management is pretty good implemented... Continue Reading →
Java provides built-in ready-to-use annotations as well as the possibility to create one's own annotations. Annotations allow to add metadata which expresses explicit context and/or intent to various Java structures (target) as classes, methods, attributes... Annotations do not impact the behavior of their target. They are interpreted by dev tools, the environment, or the reader.... Continue Reading →
Every Java program running has at least one thread, "main", automatically created by the JVM. Each thread is represented by an object of type java.lang.Thread. Thread.currentThread(); // returns currently running thread On parallelism and concurrency Before starting, I'd like to share this definition of concurrency and parallelism I found on the Oracle blog: The confusion...

Even though it's sometimes taboo to say it out loud, we're all doing our job for a main purpose: earning a living! Yes, we might see an opportunity to grow personally, to improve, to make contacts, to deepen a passion in our career (that's all I hope for you, because otherwise the job gets boring...

JDBC is a database neutral Java API in the java.sql package that allows connectivity and operations on databases. JDBC drivers provide database specific implementations of the API (for MySql, PostgreSQL, DB2… as examples). Driver libraries are made available to the application class loader via class or module path. Connecting to the database The database driver... Continue Reading →
Possibility to organize a projects in modules appeared in Java 9. In this post, we'll have a look at differences between non-modular ("legacy") projects and modular projects in Java, see how modules are created and how modular applications are run, and highlight gotcha's for those taking a certification exam covering Java modules. A Java module... Continue Reading →
