Depending on the time of the day a friend, a colleague, a wise guy. The beauty of the world is its sense of humor to show humans their way by letting them search their own.


  1. Print what you enjoy

    Today I went ahead and handed out a copy of my University thesis to the professor who mentored me while writing it. And I recalled why I recently spend more than 100€ to print multiple copies. …

    On my server backends, all volumes are encrypted. The raw block storage is provided by my hosting provider.

Well, I was able to step back a bit and let better people for the job handle it.
