In a previous blog post we learned about the default input sources that are used by Helidon SE. The list of input sources is different based on which artifacts are on the classpath of our application. When we write tests for code in our application that uses the default configuration created by Config.create() we must take into account that different input sources are used. Also here it is based on the artifacts that are on the classpath. That means that different files with configuration data are loaded, eg. a file application-test.conf when we have the artifact helidon-config-hocon and a file application-test.yml if the artifact helidon-config-yaml is on the classpath.

Blogtober, een jaarlijks terugkerend initiatief waarin onze collega’s elke (werk)dag in oktober (veelal technische) blogs delen! Echt iets voor onze developers, mensen vanuit de inhoud, die hun kennis op deze manier met de wereld delen. Tot vorige week mijn collega Erik Pronk als ‘geintje met een seintje’ liet vallen dat hij nog wacht op een blog van mij. Mijn eerste gedachte: grappig, niks voor mij. Mijn tweede gedachte: challenge accepted!

In my previous blog post Prompt Engineering: Tool or Threat to Software Engineering?, I discussed what Prompt Engineering is and how it can be used to help us as software engineers. In this follow-up blog I will dive into Claude 3, the latest AI from Anthropic, and how it can impact us as software engineers.

In this two-part blog post, we’ll explore how data exfiltration to GitHub can be carried out from a Windows 10 workstation and how to investigate such incidents. Part 1 focuses on how data can be exfiltrated using Git and GitHub. In Part 2, we’ll dive into forensic techniques to retrieve evidence of data exfiltration and determine what was sent from the workstation.

Misclicked and stumbled on this blog? I can relate, every time using the UI of a cloud provider I’m always nervous I make errors in configuring my resources. In answer to this DevOps is embracing GitOps, DevOps taking development best practices and applying them to infrastructure automation.

If you run multiple batch updates in postgres, you may run into deadlocks.

We’ll look into why this happens and how we can prevent it.

There are many ways to analyse and write down business needs and hand them over to developers for implementation.

In many cases knowledge and information gets lost in translation and/or developers don’t understand exactly what to build and come up with their own solutions and the scope gets bigger and bigger, also called scope creep.

So, how can we get to a shared understanding of the business needs and prevent scope creep?

This is where the combination of EventModeling and ShapeUp comes in play.

There are 2 broad extremes when doing Scrum. To make scrum-items based on tasks or on functionality.

When we use Helidon SE we can use the Config class to pass configuration properties to our application. The static method create() creates a default configuration. The Config class is then configured to support different input sources. This configuration reads configuration properties from the following sources in order:

The last input source behaves differently based on which classes that can parse a configuration file are on the classpath of our application. If we use the helidon-config artifact on the classpath then the configuration file read is application.properties. To read a JSON formatted configuration file we must add the helidon-config-hocon artifact to the classpath. The file that is read is application.json. With the same artifact we can read a HOCON formatted configuration file that is named application.conf. Finally if we add the helidon-config-yaml artifact to the classpath we can read a YAML formatted configuration file that is named application.yaml or application.yml. Helidon SE will only read one configuration file from the classpath with the following order of preference:
