For those who don't recognize the name, this is the same judge that learned some Java for the Oracle v. Google case (and has an undergrad degree in mathematics). Every time I read his name I know it's going to be a fun ride and the lawyers will not be able to get away with anywhere near as much shenanigans as they usually do. Although his ruling regarding API copyright in the Google case was overturned, he has a really strong record of making judgments that stand the test of appeals.
I vote Alsup for Ginsberg's seat.
