A little over four years ago, Mark Reinhold (Chief Architect of the Java Platform Group at Oracle) stated in his blog post “Moving Java Forward Faster“: “For Java to remain competitive it must not just continue to move forward — it must move forward faster.” In that post, Reinhold proposed “that after Java 9 we adopt a strict, time-based model with a ...

OpenJDK 18 Early-Access Build 16 (2021/9/23) is now available and includes the implementation for JEP 413 (“Code Snippets in Java API Documentation“), which is targeted for JDK 18. The objective of JEP 413 is to “introduce an @snippet tag for JavaDoc’s Standard Doclet, to simplify the inclusion of example source code in API documentation” and the JEP itself covers the ...

More of my clients say they want business agility. (That’s a good thing.) Yet, we don’t share a common definition of it. My clients mostly discuss their mindset. Mindset might help people, but it’s not sufficient. Instead, let’s consider how to see management’s adaptable and resilient actions. Those actions show that managers change their actions in the face of new ...

I have great respect for Jenkins as a tool, but each deployment of Jenkins tends to become a Snowflake over time with the different set of ...

A mobile app lifecycle is divided into various stages, from its first line of code to the submission request. Within these stages, one aspect that holds the key to creating an app is its testing. This field carries the burden of quality and stamps an application to guarantee that no storm would break it down. In this blog, we will ...

A poor man’s multiple-repository build system Refactoring feature branches across multiple repositories A common use case when working with multiple, dependent repositories is to use git flow to create multiple feature branches: kivakit [feature/simplify-log-api] kivakit-extensions [feature/simplify-log-api] If project(s) in kivakit-extensions here depend on projects in kivakit, refactoring code in kivakit can propagate code changes to kivakit-extensions. Then both feature branches ...

KivaKit applications can be configured using the settings api, but there is an easier way to configure an application for deployment built right into Application. By default, Application looks for the switch -deployment=[deployment-name]. If the switch is present and deployment settings can be found, KivaKit will load all of the settings objects in the named deployment into the global settings ...

In this post we will explore the transition from a classic layered software architecture to a hexagonal architecture. The hexagonal architecture (also called ports and adapters architecture) is a design pattern to create loosely coupled application components. This post was inspired by a German article from Silas Graffy called Von Schichten zu Ringen – Hexagonale Architekturen erklärt. Classic layers Layering ...
