About me

Hi. I’m Tim, a true East Frisian. In my blog I deal with topics that I am always enthusiastic about, mainly in the areas of Linux, software quality and free software.

Testorakel
In Greek mythology, oracles were sacred sites where the gods shared their wisdom and prophecies with humans. These oracles were considered infallible and were regarded by humans as a source of truth and knowledge.

In software testing theory, the test oracle symbolizes this source of wisdom and knowledge by providing the correct results that testers can use as a reference. A test oracle is thus a kind of “source of truth” that enables testers to verify the correctness of a system or software. By comparing the actual results with the expected results, a tester can determine whether the system or software is functioning correctly.

Professional
From the day a Schneider CPC 464 found its way into my parents’ house, my career path was set. Before that, I wanted to be a cook or an elevator operator, but from then on it was going to be something to do with computers.

I took my first steps into working life as a software developer and wrote components for output management, which were used by major customers with printing and packaging centers. I moved to Switzerland and, as IT & Security Linux Administrator, took on the task of averting all serious IT threats to ensure the continuous operation of the mail center. Finally, I returned to my home country, where I have since been working as a software tester for a software manufacturer of critical infrastructure in the energy sector, ensuring the necessary software quality so that the lights don’t go out anywhere.
