This isn't tech related but I found it kind of sad. I've never met the man myself but I know a lot of people who have and I've never heard a bad thing about him.
The irony is he's probably one of the biggest celebrities in the world yet I'd be surprised if anyone who reads this will recognize his name. If you have a couple minutes watch the video below. It's a good tribute to a man who deserves credit for his contributions.
R.I.P. Don
