My friend of 40 years, Kryzstof Cetnarowicz, seems to have left this world sometime ago. I got to know this sad news thanks to a chance conversation with the wife/widow of my PhD guru.
Kryzstof was a Professor at the AGH University of Science and Technology , Krakow, Poland, where I met him last in 2009.
In fact, Kryzstof had invited me for a talk on the role of non-functional specifications in software engineering, at his institute.
It was also a beautiful holiday for my wife and me. Thank you Kryzstof, may peace be with you forever.
To come, to know, to learn to part, is the sad tale of many a human heart.
Adieu cher ami.
