Cloud Development Environments (CDE) - All Aboard! In the world of software development, onboarding new developers can be a real headache. Tool installation, environment configuration, resolving incompatibilities… These are all problems that Cloud Development Environments (CDEs) promise to solve. But before diving into the world of CDEs, it’s essential to understand the technologies that underpin them: DevContainers and DevFiles. DevContainers and DevFiles What is a DevContainer? A DevContainer is a specification that formalizes the description of a containerized development environment....

In modern application development, interaction with web services has become essential. However, what happens when these services are unavailable, still under development, or simply unstable? This is where Mockoon comes in to save the day. What is Mockoon? Mockoon is a powerful tool for simulating web services. But before diving into its features, let’s clarify the concept: A mock is a controlled imitation of a real component. In the context of web services, it can be an HTTP response containing mock data....

Introduction StableValue is a new feature introduced in the preview version of JDK 25, aimed at improving the handling of immutable objects in Java. This innovation allows certain dynamic values to be treated as constants, offering performance optimizations similar to final fields, while providing greater flexibility regarding when they are initialized. The JEP related to this evolution is JEP-502, with the following defined objectives: Improve Java application startup time by fragmenting the monolithic initialization of application state....

Introduction SVG images (Scalable Vector Graphics) are widely used on the web due to their ability to scale without losing quality. They are XML-based files that can be easily included and modified in a web page. In this article, we will explore how to add HTML links to these images, dynamically change their style with CSS, and finally how to make them responsive. Adding HTML Links to SVG Images Adding HTML links to an SVG image is very simple....

When working on a versioned project, it is relatively common to end up with a “stack” of branches. What could be more frustrating than having to rebase all the other branches on top of the first one when updating it? This process becomes even more tedious when the number of branches is high or when they are regularly modified. Git version 2.381 introduces a solution to this problem: the update-refs rebase option....
