I seem to remember that he didn't exactly start from zero, but had some idea prior to that and simply learned more about Java. Just sayin', because I think it makes it even better.
I thought his ruling was extremely well thought out in that case, and yet a Federal Court, which is apparently very patent friendly, has accepted the case on appeal. So I can't wait to see what ridiculous spin they will try to put on Alsup's ruling, if they do indeed side with Oracle. I'm not too worried if they do, because I think the Supreme Court will have more common sense and side with Alsup's ruling.
