2026-03-15

Misplaced Expectations and the Limits of LLMs Over the past three years, LLMs have gained enormous popularity and were brought into widespread public awareness largely through the efforts of OpenAI.

Gradle 6, Jacoco and allJvmArgs don't go well togheter

2020-05-04

Recently, I had to migrate a Gradle 4 project to the newer Gradle 6. One problem that I found was that the Test Coverage Plugin for Jacoco did not work anymore.

Unfortuantely, the tests set also JVM options, e.g. for increasing heap, using the setter allJVMargs. The following example build.gradle of a gradle multi-project illustrates this: …

2017-02-17

Single Sign-On Wikipedia describes Single Sign-On (SSO) as a property of access control of multiple related, but independent software systems. With this property a user logs in with a single ID and password to gain access to a connected system or systems without using different usernames or passwords, or in some configurations seamlessly sign on at each system.
