Surely not? I was told just last week by the inestimable Mr. Mogens
Norgaard (who we all know as the source of truth) that Gaja's real name is
Gaja Vaidyanathanathanatha, and he's about to take on a top-secret new
career (details to be revealed at the DB Forum in Denmark in October) ...

Mladen,
As one of the authors of DBA 101, I appreciate your plugging my book
for me. But Gaja Vaidyanatha (correct spelling) and Kirtikumar
Deshpande (both on this list) are the authors of the book I think you
meant to talk about: Performance Tuning 101.
Marlene (has she now moved onto single name status, like Cher and
Elvis?) is my co-author, along with James Viscusi
