Compared to Dependabot, I love Renovate’s capability to update Docker, Docker Compose, and Kubernetes files. I’ll use it from now on.

Did you know GitHub and Google Cloud have all the infrastructure available to get short-lived tokens securely? Handy for Java devs and more!

Time to spruce up your GitHub! In this article, I want to highlight some files that you can use to beautify your GitHub repository.

The Java GitHub Actions that rules them all! Hey, everyone check Carl Dea’s 3rd and final instalment Lights, Camera, Action: GitHub Actions with Java

When picking a build distribution with the current version of GitHub Actions setup-java@v2 you really only have two choices: zulu or temurin.

Learn how to create a GitHub Action job that will build and test a Java-based project using Maven or Gradle.

Most people will start with using “git blame” (or the respective functionality within their IDE/editor).

But on most non-trivial projects, you usually end up with a refactoring commit, a rename, or a trivial cross-project fix like switching to another assertion library. At first glance, we only see the most recent changes, not the most important ones.

We need to carefully remove layer by layer of sand and dirt that has been swept over the real changes to unearth them.

Both for Maven and Gradle lovers there are different possibilities to build Java executables and GitHub provides the free tools to do so!

I decided to switch to an alternative approach in GitHub Actions.

Instead of committing, I updated the script to open a Pull Request. If I need to run the demo, I’ll merge it (and pull locally); if not, it will stay open. If an opened PR already exists, the action will overwrite it.

Now, I can schedule the action more frequently.

In this article, Almas and Frank show you how to start with an idea for a game and bring it to life in a prototype application. We will then modify the application to run on a Raspberry Pi and on a mobile device.

To give some background, some time ago my 10y old son challenged me to create a Snake-like game with emojis. He selected the emoji images and I “only” needed to do the programming bit, the easy part… Luckily Almas asked me if I had a topic for some pair-programming for his YouTube channel, and his question turned into a three-part series. My son is delighted because his idea is now a real game!
