Effective Perl Programming: 60 Methods and Rules for Scripting Better Programs (A-W Developers Press)
Effective Perl Programming: 60 Methods and Rules for Scripting Better Programs (A-W Developers Press)

4.0 von 5 Sternen Well written, useful guide for beginners and intermediates, 28. Juli 2000
Effective Perl Programming is a concise, well written guide that is packed with useful Perl tips. The book is a series of "Items" (in the same style as Effective C++) that are each a tip about how to use Perl. Each tip is accompanied by a detailed description that discusses the pros and cons or each tip and several examples. The tips are then arranged into sections such as "Regular Expressions" and "Object Oriented Programming". In a relatively small book the authors manage to present an enormous amount of helpful information.
This book is a worthwhile purchase if you are a new or intermediate Perl developer. The tips presented here will really help improve your code. However, if you have been working with Perl for a while then this book isn't worth the money. There might be a tip or two that you don't know, but chances are you know most of what is presented.


Power Eating
Power Eating

4.0 von 5 Sternen Standard material, but well put together, 14. Juli 2000
Rezension bezieht sich auf: Power Eating (Taschenbuch)
The book presents the standard high carb approach to gainingmass. It is material that you will find in many books, but Kleiner presents it in an organized manner and covers implementing this diet from all angles. She talks about all of the macronutrients -- how much you need of each and why, and some of the micronutrients. After discussing what to eat she talks about how to use the information to achieve your specific goals (building muscle or burning fat) and provides detailed plans for these goals.
I don't think this is the ultimate in diet books, but it is a worthwhile read if you are looking for a pretty complete book on high carb diets. However, if you own a similar book (such as Optimum Sports Nutrition) this isn't worth the money.

5.0 von 5 Sternen A fantastic addition to your Perl collection, 14. Juli 2000
Rezension bezieht sich auf: Object Oriented Perl (Taschenbuch)
I was a bit skeptical when I was first handed a copy of Object Oriented Perl because I tend to be biased toward O'Reilly books. However, after reading it I felt it is one of the best Perl books I have come across. Most Perl books deal with Perl as a scripting language. Conway treats pull like a real development language. He gives the standard introduction to object orientation and objects in Perl and then quickly moves past this to look at some of the unique features of Perl's OO development in Perl. For example, he covers blessing every type of reference possible, why you would want to bless a particular type of reference and what the pros and cons are of each approach.
Conway also gives a very thorough coverage of implementating true data encapsulation in Perl and presents several methods for doing so.
Another thing that struck me about this book is Conway's attention to detail. In his code samples, he carefully explains why each line was written a certain way. He even notes which version of Perl a certain feature or module first appeared in.
All in all, a wonderful book. Even if you have been developing in Perl for a while this book has something to offer.


The Greenwich Diet: Lose Fat While Gaining Health and Wellness: Lose Fat While Gaining New Health & Wellness
The Greenwich Diet: Lose Fat While Gaining Health and Wellness: Lose Fat While Gaining New Health & Wellness
von Carlon M. Colker
  Gebundene Ausgabe
Preis: EUR 20,23

3.0 von 5 Sternen Interesting, but not complete, 11. Juli 2000
The Greenwich Diet is another take on today's popular low-carb diets. It is similiar to many low-carb diets, but addresses some of the concerns associated with those diets. The diet involves consuming a fair amount of high quality protein. Unlike other low-carb diets, animal fats are restricted. Colker seems to feel that saturated fats are a health risk and concentrates on consuming healthy fats -- fish oils, etc. The only carbohydrates allowed on the diet are incidental carbs that occur in vegetables. Direct carbohydrate sources such as breads and pastas are off limits. Vegetable consumption is very high and is used as a source of fiber and other nutrients.
On the downside, I was disappointed with the lack of detail in the book. Colker describes the processes that cause a low carbohydrate diet to result in fat loss, but doesn't give the detail I was hoping for. After reading the book I found myself purchasing additional books to help understand how these diets really work.
Since Colker was a former bodybuilder and powerlifter I was hoping for more information about how this diet relates to athletes. Exercise is covered in the book and he emphasizes how important exercise is to include with any diet, but he doesn't discuss the issues of athletic performance and this diet. In particular I was looking for information about energy and muscle growth in carbohydrate restricted environments. For this information you'll need to look elsewhere ("The Ketogenic Diet").
Finally, other reviews have complained about the many references to a particular supplement company in this book. On my initial read I didn't think too much of these, especially after reading the note at the end of the book which states that Colker receives no money for promoting these products. However, on subsequent reads I think he could have de-emphasized this company a bit and talked about the supplement industry as a whole. The repetitive plugs have made me a bit more skeptical.
One closing note -- I tried emailing the address given at the end of the book with my questions and was pleasantly surprised to receive a reply from the author within a couple days.


Winter Hikes: In Puget Sound and the Olympic Foothills
Winter Hikes: In Puget Sound and the Olympic Foothills
von Bob Mooers
  Taschenbuch

4.0 von 5 Sternen Useful year-round guide, 11. Juni 2000
Winter Hikes is a useful guide for all seasons. For the most part, the only thing that makes the hikes in this book "winter hikes" is their elevation. In reality the hikes in this book are enjoyable all year.
The summary information provided with each hike includes the distances, estimates trip time, trail type and other useful information such as the potential avalanche danger on the trail. It also includes the starting elevation and elevation gain of the trail so you can judge the potential for encountering snow.
The rating system takes some getting used to. Since many of the trails are in the lower elevations, don't expect jaw dropping views at every turn. Even highly rated trails will spend a lot of time in the woods.
Although I have said this guide is useful year-round, I think it is best for 3 season hiking. During the summer you should use other guides that provide better coverage of the high elevation trails.


Running Microsoft® Excel 2000
Running Microsoft® Excel 2000
von Mark Dodge
  Taschenbuch
Preis: EUR 39,43

4.0 von 5 Sternen Very complete coverage of Excel, 8. Juni 2000
Rezension bezieht sich auf: Running Microsoft® Excel 2000 (Taschenbuch)
Running Excel 2000 provides a very complete look at using Excel in most day to day situations. The general usage information is well structured and each topic is covered in detail.
For me the real value in this book comes from the section on analyzing data. The author discusses the worksheet functions but then delves into common analysis situations. Their coverage of financial analysis discusses all of the different financial functions and how to use each of them. The statistical analysis section talks about each of the different distributions supported and when each should be used. Finally they present a what-if analysis section that shows how to use Excel's solver and scenario manager.
The book even touches on Visual Basic, but only enough to get your feet wet with Excel's macros.
All in all a very good book.. much more than I was expecting from a general "how to use Excel" book.


MS Excel 2000 Power Programming with VBA (Computing)
MS Excel 2000 Power Programming with VBA (Computing)
von John Walkenbach
  Taschenbuch
Preis: EUR 50,07

4.0 von 5 Sternen Great for users of all levels, 1. Juni 2000
I am always a bit skeptical when another computer book that is several inches thick is released. Surprisingly there is useful material throughout this volume. Walkenbach covers Excel programming from start to finish in a way that programmers of all levels will understand. He begins with a bit of Excel history and moves into simple VBA development and eventually covers various "advanced" topics such as pivot tables, charts and user forms. His writing is clear and there are plenty of examples throughout the book. He is even careful to point out version compatibility issues.
Experienced programmers will find most of the book skimmable. In about an hour you can pick up most of the VBA syntax and be on your way to developing simple applications. Some space is devoted to software development methodology, but not too much. Walkenback strikes a nice balance between giving new users the information they need to know and not straying off topic.


My Best Mathematical and Logic Puzzles (Math & Logic Puzzles)

4.0 von 5 Sternen A great collection of diverse puzzles, 23. Mai 2000
I have accumulated quite a few puzzle books and was never fully satisfied with any of them until I heard about Martin Gardner and decided to pick up one his books. The puzzles are diverse, ranging from word problems to geometry problems.
The solutions given are very complete and actually take up the majority of the pages in the book.
On a somewhat related note, if you happen to be interviewing in the technical fields you may run across interviewers that ask brain teasers. You'll find many of those problems (or ones that are very similar) in this book. For technical interviewing this makes a good study guide.


Pattern Recognition and Neural Networks
Pattern Recognition and Neural Networks

3.0 von 5 Sternen I ended up returning it..., 16. Mai 2000
After reading the reviews I was really looking forward to reading this book, but ended up a bit disappointed. The editorial review and introduction lead me to believe that there was difficult material in the book, but I would be able to make my way through most of it.
I came at the book with a computer science background (and no prior neural network experience) and found the material rather difficult to follow. The statistics and math needed to really follow the book was more than I expected.
This doesn't mean the book is bad. After skimming through it a couple of times I really believe that the other reviewers are right -- this is a great resource on neural networks. However, just be sure you have the appropriate background to really get the most out of it.
If you are looking for an introductory book on neural nets or are a little rusty on your statistics and math I would recommend looking elsewhere.


Nikon N6006/N8008S/N6000 (Magic Lantern Guides)
Nikon N6006/N8008S/N6000 (Magic Lantern Guides)
von Paul Comon
  Taschenbuch

4.0 von 5 Sternen Great manual and beginner guide, 8. Mai 2000
I had lost the manual to my 6006, but found this in my camera back and started reading. It covered the operation of the 6006 very well and provided some very basic tips on using the functionality the camera offers. I found that it was worth reading the sections on other cameras just to pick up additional photography tips.
The book also provides a nicely detail look at the various accessories for your Nikon. It covers flashes and the various additional lenses that are available. I found the section on lenses particularly useful because it talks about when each type of lens is used and discusses the pros and cons of the different lens types.
All in all, a great accessory for your Nikon.
