I didn't have the book with me at the time, so I was talking by heart,
from my head. As I am getting older, my memory is obviously playing tricks
on me. I humbly apologize to everybody whom I might have offended by my
bad spelling, distorting title or forgetting co-authors altogether.
I didn't want to insult anybody, it's just my advanced age which is
equal to the answer to the question of life, universe and everything.

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
