PROBLEM: A book full of examples of how NOT to write perl . I couldn't resist the title, so I got this book. Unfortunately, I cannot reccommend it to people who want to learn to write better Perl, execpt as a source of examples of the mistakes you should avoid.    For example, in one of the earliest examples, the authors uses "return undef" in a situation where the return value of the routine is assigned to an array, to indicate the routine didn't find any of whatever it was looking for. Unfortunately, this is a mistake, the correct code would be to use "return;" all on its own. The correct solution produces an empty array or interim values; the mistake creates an array containing one element, 'undef'.    There are a number of similar mistakes which indicate the author is in over his head, writing things he doesn't understand; the editors know even less about the matter; and the code was never tested and verified for correctness.    If you want to learn Perl, get "Learning Perl"; If you want to improve your Perl, get "Intermediate Perl.    To

PROBLEM: When a High Initiate in ECK  becomes twisted by the Dark Side . What so many past and even some current chelas overlook is that there is a difference between Sri Harold Klemp, the man, and the ECK which uses and continues to use him as ITS divine channel in all the worlds of God.     Recently I took the fourth initiation in ECKANKAR. Yesterday, while in contemplation I sang my new secret word with my attention on the  current Living ECK Master and experienced the Light of God.     Ford Johnson's assertion that chelas are prevented from becoming Masters is a falsehood. Before Millie Moore translated she had reached the Ninth Initiation, the point at which ECK Mastership commences.     It's sad to see a former High Initiate like Ford Johnson who has become 'twisted by the Dark Side'

PROBLEM: Out of Ideas . Back in his day Heinlein was the greatest writer of science fiction for adolescent boys. Unfortunately, that day is long past, and Heinlein has wandered far from his strength.  This book fills in some gaps from Time Enough for Love and is a rehash of much of that story from an alternate viewpoint.  As was the case in Time Enough for Love, sexual coupling of old men and young girls is a recurring theme. Examples: The two female lead characters brag to one another how they had their first sexual experience at ages 12 and 14 and with men 4 times their age.  The male lead goes back in time and has sex with his sister, then a young teen, and he, at this point, the oldest man in human history.  To make all this go down easier, the young females are the sexual aggressors and the old men are pursued, and said to be 'tripped' if she has her way with him.  There is a lot more of this 'weird sex', but I will move on.  This is not really a science fiction story per se, but there are a few trappings of science fiction used to decorate the story.  Most of it takes place in the first half of the 20th century in mid America.  There isn't really a plot.  The book is a series of anecdotes occuring in the life of this unlikely heroine, seemingly Heinlein's feminine ideal.  It is obvious that the author has run out of ideas at this late point in his career.  This book would not have been published if it was the work of an unknown author.
