25 years ago, a colleague suggested that I should write what he called "a Linux book". I liked the idea and I promised I would. Years rolled by, and here I am, a quarter of a century later, acting on a promise. As Steve Jobs once said, 'Ideas without action aren't ideas. They're regrets.'

To my family my mother, father, and brother, for putting up with me over the course of the last 25 years which led to writing this book. To my TA, Jasmin, for both helping me to improve and offering insights into various topics covered in this book.

To my son, Luka, for showing me how young people can be both talented and focused, especially when faced with problems that require innovative solutions.

To my partner, Sanja, for driving me on in everything that I do.

Here's to not having any regrets.
