I can't say it comes as a surprise but another great mind is leaving Oracle. This time it's Jeff Bonwick, the man behind the slab kernel memory allocator in Solaris and more recently (together with others) ZFS. It is indeed disturbing to see that so many of the innovators from Sun, who stayed with the company thought terrible financial times are now leaving.
This means that most high profile persons behind Fishworks (S7000 appliance), DTrace and ZFS have left the red ship. Jeff Bonwick, Adam Leventhal, Bryan Cantrill and Bill Moore. There are of course many good people still at Oracle, but the people I have been following seem to be on the move.
Best of luck Jeff, I'm sure you will continue to break new ground somewhere else.
