Oh dear, that's very sad news
I never knew unkamunka, but sensed from his posts in this forum that he seemed very passionate about this project, and probably with little reward apart from the knowledge that a lot of people appreciated his efforts. To me that passion tells the story of someone who's willing to spend a lot of time and effort to help others, which is probably the best time and effort any human can spend.
People like unkamunka certainly represents the best of the world of Open Source Software.
I hope he got feedback enough to know that his work was appreciated. My condolences go to his family, you have every reason to be proud of unkamunka.
Rest in Peace.
