The explanations and expositions are clear and concise and should have you understanding most of the material with some thought and effort. Because let's face it: no book will learn for you or magically transform itself into your ability without some effort (however much or miniscule) on your part. I find mathematics fairly easy (I'm an engineer), so this book was quite good because some of the questions do take a bit of time (some challenge is always good!). A few of them are VERY difficult, though I've yet to run into one that is by my worth unsolveable. But this is dependent on your mathematical ability.
Altogether, not bad and will teach you introductory calculus and multivariable claculus with some useful appendices as well, including some complex numbers (but not enough). Damn thing weighs about 10lbs though...:)

If we think about understanding e-commerce, we soon realise that we have to examine the intersections among technology, economics, and behaviour. While there is no shortage of texts on the enabling technology, it changes so rapidly that any available textbook is likely to be obsolete. Several texts have recently been published that focus on the economics of networks, so that gap seems to be filled. That leaves us with online behaviour, an important niche that this book explores in an interesting way.
Strengths? After a mercifully brief introduction to technology, the text alternates between a demand and supply perspective - Chapter 3 (Web strategy: attracting and retaining visitors) leads us to an examination of the use of web technology to support marketing (Chapter 4), promotion and purchasing (5), and distribution (6). Service quality and pricing are briefly addressed (Chapters 7 and 8), and the book ends with a snappy little review of postmodernism in the context of e-commerce.
Weaknesses? The text is not likely to interest the wirehead audience, even though they really would benefit the most from a change in perspective. The legal issues are left to others, an unfortunate omission from both the business and social science perspective. It is very suitable as the main text for an undergraduate e-commerce survey course, and as a supplementary text for courses in social science, business, Communications, and Law.

In short, this book gives the reader the best and worst faces of modern stringed instrument (banjo and guitar) collecting. On one hand, you have an educated and articulate individual who has an obvious appreciation for finely crafted instruments. To Dr. Van Hoose's credit, he did his homework and clearly wrote the information that he had gathered (unlike some other collector/writers). On the other hand, this book, to some degree, reinforces the popular opinion that acquisition equals expertise. Collectors such as Akiro Tsumura (with his "1001 Banjos" book) or Scott Chinery (who had the brainstorm and funds to commission a fleet of blue guitars from the world's top builders, to add to his already huge collection) are regarded as experts, whether they can play a note, dress a fret, conduct research, or do anything else that would be considered expertise when writing about musical instruments. Coincidentally, this view seems to be held in high regard by top instrument dealers (such as George Gruhn, who wrote the forword for this book). It turns out to be a mutually beneficial arrangement, to be sure.
If you obsess over guitars, this is a good book for you. Believe me, a lot of work went into it. The book is loaded with plenty of information and a good helping of pictures, and it IS the be-all-end-all for this particular subject. If you don't obsess over guitars, this book will get old pretty fast. I really DO appreciate the effort that was put into this work, but I think it just ends up being a little too much for anybody but the most die-hard fans.

The author first talks about the foundation of efficieny, scalability, parallelism..... etc.
Second part is the discussion of multithreading. The problems like race conditions, mutual exclusion, thread monitors, parallelizing loops and synchronization are discussed in great detail.
Some algorithms for increasing efficiency and performance diagrams are provided throughout the book to give reader a clear view in understanding the topics.
The last part is about network programming which talk about socket and simple messaging architecture.
The strength of this book over the other java performance tuning book is that it integrates some algorithms into the code(major factor) to increase performance rather than just talks about in preventing the use of certain low performance java code(minor factor).
However, the book seems losing the way in targeting audience. The content of the book doesn't specific to any field.

In the case of older speeches, the selection is very good, considering the restraints of time, and the readers are uniformly excellent.
As for the modern speeches, it is a marvel of technology that we can hear these speeches as delivered. It is incredible that we can hear the voice of William Jennings Bryan. I can listen to Martin Luther King's "I have a dream" a thousand times and never tire of it! How I wish I could listen to the voice of Patrick Henry! But this selection is too heavily weighted to the modern, and many of those do not deserve billing as the GREATEST speeches of ALL TIME. Also, some of the modern speeches which are included are abridged, e.g. Reagan is cut off in the middle of a sentence, while lengthy and undeserving speeches are played out in their entirety.
Also, with only a few exceptions, the selection is almost entirely American. It is hard to understand why Jimmy Carter's lengthy speech on energy policy is included, while Pericles' funeral oration is not; or why only a small portion of a single Winston Churchill speech is included; why while Bill Clinton's complete 1993 pulpit address, in excess of 20 minutes, is included.
It would be helpful if the complete list of speeches were available to online buyers, as it would be to shoppers in a brick and mortar store.
