Mike Olson pointed me to this excellent Wired article on the disappearance and search for noted database researcher Jim Gray. Jim is apparently the sort of developer that every company on the planet wanted to hire. At this point, no one wants him more than his family. Yet he's still missing.
Mike has been involved in the search. Interestingly, as comes out in the article, so have many others, but in classic Silicon Valley sorts of ways (collective analysis of satellite images, etc.). It's a fascinating story, but one which would be much better if it simply came to a boring resolution: Jim comes home.
Not open source related, but have a read.
