I always try to improve my writing skills and this book aids in that. I will recommend this book to anyone.

This would be a handy reference for business professionals. With its good contents and fair price it sells for, I will say, "It is worth having a copy in one's library".

You might think a reference book on how to write business letters would be a dull read - but not this one! In fact, this book is fascinating and fun, thanks to the author's witty and imaginative presentation.

Whether your purpose is to sell a product, collect a payment, extend an invitation, or secure employment, this book has advice you can use. Not only does it explain how to correctly format your letter, but it also offers guidance on how to organize your thoughts on paper, how to choose the most effective words, and how to charm your readers with tact and courtesy. In addition to the numerous example letters provided throughout the book, there are five appendixes at the end, serving as a handy reference guide to such topics as grammar, punctuation, and commonly confused words.

As the world of business becomes more demanding and competitive, writing well is now more than ever a way to stand out. This book will help you do that.

I had always procrastinated writing business letters(letters, faxes, e-mail messages) especially the important ones, thinking I could never write well enough to explain my ideas.
Now I have a concrete 6-step process + several examples which lead me to write what i want in the best way.
" in a well-written & well-formatted document:
the subject line tells the story & mentions the keyword
there's plenty of white space that provides a resting place for your eyes
Paragraphs are short & reliable
Sentences are short, simple & easy to read
Key info pops out without your having to read the entire message
Headlines direct your eye to key pieces of information
Critical information is numbered for easy reading "

Tired of developing perfect business letter and email models, only to lose them in the morass of inbox materials? Frustrated about imparting the right tone and point in a business letter? Use Sheryl Lindsell-Roberts' Strategic Business Letters And E-Mail's series of sequencing steps to write a draft, design for visual impact, and create a winning letter model which can be used as a proven template of success. Letters are grouped by subject such as Customer Relations or Media Relations, and outline just why some messages succeed while others fail.

This book is a great toolbox to start my career. The examples and tips given in "Stuff You Don't Learn in Engineering School" are truly helpful. I plan on keeping it available for referencing at each and every profession that I explore in the future.

Selinger offers a condensed, easy to read synopsis of important skills engineers need to know to succeed in business, such as how to conduct meetings, time management, and decision making. The ideas are given in practical, easy to follow, guidelines, with examples. Good sourcebook for career development.

Every engineering graduate should definitely read this book. It is concise, lucid, and to-the-point.

I do not quite agree with the title in its entirety. We do learn quite a few of these things at engineering schools. However, in our relentless pursuit of gaining technical knowledge, we keep learning these things at a much lower priority. Chapter 15, "Having Fun" describes something, which is actually quite real. I have personally experienced this, where our professors would sometimes force us to go ahead and have some fun. Carl Selinger mentions many such important things, which the engineer needs to be good at including writing and communication skills.

Carl Selinger starts by referring to Dale Carnegie's famous book "How to make friends and influence people". This makes the reader, develop very high expectations about the book. Despite his best effort, his style does not live up to the standards of Carnegie. Unlike Carnegie's book, there are not many third-person examples or experiences, which have been discussed. This sometimes lends a preaching style to the writing, which can become annoying.

For someone who is inexperienced, freshly graduated and has never been taught any of the things which the book discusses about, will find it difficult to comprehend and realize the importance of learning these skills. This is primarily because Carl largely mentions personal experiences. A naïve reader might critique the book as being too one-sided. Overall, the book is very good as a reference.

The book was very readable and filled with insights. I was particularly fond of the chapters on assertiveness and leadership. The book has an excellent combination of helpful business and social tips, reasons to learn them, and methods to gain these traits for yourself.

I am always looking for good information on our fascinating profession.

when I graduated from engineering school, there was not much written for young engineers getting their first introduction to the world of work. There were plenty of books on how to "think successfuly" or "sell more" that were targeted to the liberal arts/sales types. There was very little for those of us doing technical things. This is why his book is much needed.

Carl Selinger is on target for his efforts and employers owe him a debt as well. Managers benefit because they get a window on what Carl discusses with students when they attend his seminars (which I assume is where many of the quotes from students come from).

As we go through many of the current management fads, folks like Carl seem to understand that it is the "software" (i.e., the people) that make the difference. People skills are extremely important if you expect to survive. Every good project manager I have ever worked with or sharp youngster I have had the priveledge of developing "gets it" at this basic level.

The organization of the book touches on topics that most engineering schools cannot teach.

For those of you with lower grades in enginering school than you would have liked or those of you who know a recent engineering grad or a soon to be engineering grad, this is the book for you.

This book should be in the library of anyone involved with DC-DC converters. The book covers the theory of converters and the SPICE applications are very helpful. I used the Top Spice demo to simulate the buck converter and was quickly running simulations.

This book is a must have for the power supply designer! I own about every book written on the subject, and this ranks with the top 5. I feel that it is especially valuable to the reader who has studied the subject reading other top books in the field.

Each simulation problem is well resolved with examples and a brief of theory is also included in each. Very good for Spice users but not to much useful for others simulation package users.

Christophe Basso worked very hard giving years of his life to produce the best Switch-Mode Power Supply book available, by far. I have a large collection of books on SMPS and although many are very good books, they are not nearly as complete or practical as Basso's book. He derives all his equations and then shows many real world example designs from start to finish. In my opinion and the opinion of many power electronics professionals and power electronics college students, the averaged switch model is the easiest to create and most intuitive to understand and use. Basso has digested the best information from the best references and then creatively enhanced many models and invented new SPICE models/sub-circuits you need for large and small signal analysis and simulations with the SPICE of your choice. His knowledge of creating analog behavioral models (ABM) that perform just like the real components or circuit functions, is amazing. He created ABM PWMs from individual ABM components. Everything he creates, he verifies. You buy this book at a bargain price and get a CD with all the models/sub-circuits you need to check your existing designs and start new designs with the highest confidence. Once you look at his ABMs, you will want to create some of your own because it is so much fun. In a short time, I've used his models/sub-circuits and his techniques with PSPICE to identify lack of or no phase margin in Switch-Mode Power Supplies for a huge corporation. I have many more power supplies to analyze/simulate and several new ones to design.

I've worked as a power electronics engineer for many years and I'm so thankful to Christophe Basso for working so hard and smart to produce the best Switch-Mode Power Supply book ever written. Very thorough and very practical. Get this book and apply Basso's knowledge, techniques, and SPICE models/sub-circuits to your designs and you will never have another unstable Switch-Mode or Linear Power Supply.

Once in a while a book comes along that covers a subject in such detail and yet is chocked with examples that are easy to prove and use by students and designers in the field as this one. It is evident that Mr. Basso went to great lengths to make sure that users of different spice software platforms were included by supplying a CD with models and demos for all the major platforms. I don't know of another offering that deals with closing the feedback loop in the detail as this book does. I think any serious graduate program should consider including this book as a text. Money and time well spent; it is my second reference for serious SMPS work.

That's an exciting and useful book in all synthesis manner: almost no gate-level circuits inside, as in modern EDA tools it don't need to.

A lot of algorithms (eg. log, sin, sqr...) which is beyond fast adders or one-cycle multipliers that can be easily found in many DSP hardware books. In fact, we make and sells a DSP state-machine chips in almost a million pcs that certain arithmetic circuit blocks is inspired by the book.

This book is quite original in its presentation. The selection of implementations is of interest.
The theoretical foundations are sound and presented in a well organized way.
The applications cope with the actual technology: especially in what concerns programmable devices.
It is a good book for advanced students and a must have tool for the professional designer.

In the part dedicated to general algorithms, very interesting new presentations or generalizations, made this work attractive at the theoretical point of view. Extensions of booth algorithms and generalizations to base B operation make the work innovative at the mathematical point of view. At the implementation level there is very good and innovative ideas towards special applications in FPGA (mainly Xilinx oriented). It would have been desirable to cope with some other technology, but the book may be considered self containing anyway.

The presentation of arithmetic theory and applications is innovative. Some of the topics are inedited; they present new approaches for both algorithmic and implementation aspects. It is a very interesting reference book for what refer to computer arithmetic in general and special purpose arithmetic circuit in particular.

There's a lot to like here. It goes over all the low-level stuff you could hope for, including creative number system, carry-lookahead, Booth encodings, and SRT division. It addresses some of the needs of crypto people, with discussion of finite-field arithmetic. It even gives enough intro to residue number systems for the desperate developer to gain a toehold - 10,000 digit addition or subtraction can be done in a few-digit time, as long as the expense of getting into and out of RNS are amortized.

That's all good for someone who can't trust their synthesis tools for good carry chains, or for someone headed way into the weirdness. The ranges where I live get distressingly little attention. If you need a dot product of two vectors, this will do a great job on the multiply and add steps as long as you can work out all the pipelining implications for yourself, but those were never the problem - it's the parallelism (how many multiplies can you run? how deep is your adder tree? or do you have something better?). It's the memory bottleneck (what do you mean you read "a word" from memory? I want 100). It's the numbers that number-crunchers use, i.e. IEEE 754, which get a moment of mention at the beginning and at the end. Those start turning strange with NaNs, signed zeroes, and denorms, then go totally off the rails when things like Intel (not always IEEE) compliance arise from the deep.

This could be a good text for a mid-level practitioner or student, fluent with logic design but blissfully ignorant of numerical analysis. If that's your trajectory, you'll spend some amount of time where this book lives. Then you'll advance, and it will no longer serve you. That's not a criticism, since every level has its own needs, but the prospective buyer should weigh needs to be met against needs that this meets. Not all readers will find a match.

The teach your self visually books are fantastic for easy learning, I have the excel and access books, and they are both great.
Thanks to the book creator!.

One of the newest and brightest features of Microsoft 2007 which includes Excel 2007, is the addition of The Ribbon, which replaces toolbars and menus in previous editions. This is quite complex and not very user friendly, but when you learn it, it can be great! If you struggled with old menu bars, you will definitely struggle with the New Ribbon.

The series of Visual Books has been quite popular, mainly because anything as dry as instructional material is greatly enhanced by pictures. The colorful graphics that define the category of work you want are bright, amusing, informative and large. An example is for the section: protect a password shows a big yellow book with a key lock; or change data color shows paint cans and one color spills onto a worksheet. The computer illiterate can "get the picture" even if you don't know what the book refers to.

However, my grief comes with too many big pictures and not enough pictures of the screen. A most important element is viewing the screen, but each pic of the computer screen is way too small. But you do have explicit instructions in the sidebars.

My question remains, why couldn't the writer incorporate larger-size views of the computer screen. This is so needed, because of the elaborate menu bar...or ribbon as it is called in Excel 2007.

Other than that, one point is the Database section has been advanced from the 2003. This element of the software eliminates the need for ACCESS 2007, which is much more advanced. So, if you don't want to explore the challenging ACCESS, you can simply use the Database function on Excel. This works great for smaller projects.

Overall, this is one of the best books for learning excel. Graphic and text are well spread out, it is user friendly, colorful and includes a ton of help.......Rizzo

This book is more than the five star rating. Visually Excel learning the only right way to go. The book is excellently done too.

I use this book everyday, easy to understand, easy to use. My spread sheets look just as good if not better than those in my work place that do this everyday. I am just slower, but who would know.

For those of us who lack computer savvy, a book like this is an essential. Personally I learn much better if I can read text AND look at a picture. Never really having done a spread sheet before, I learned in no time at all. I keep the book right by my computer. I have found all the 'Visually' books to be helpful

This is a wonderful book! It also with Four Arguments for the Elimination of Television have inspired much of my research and thought.

This book is an exploration into the effect television has on the viewer's state of mind. The organization and style of the book read very much like a dissertation that has been reworked slightly for publication. The style of writing is very academic, and is geared to academic rather than general audiences. The first two chapters are pure literature review covering information reception and previous research about television viewing. The next chapter discusses the research methods. The main study involved a group of about 100 adults living near Chicago in the 1970s, who were asked to keep activity and mood diaries over the course of a week. The data from this study were combined with data from a number of other studies that examined television viewing habits of mostly Americans and Canadians. The remaining chapters cover various aspects of the results and discussion, including: how television fits into the scheme of leisure time, how television affects viewer's moods, how television affects family life, why some people view more than others, uses of television, television and marketing, and television and personal growth. As with a dissertation, sources are cited within the text and each chapter has extensive endnotes for further explication and references. The questionnaires used in the study are reproduced in the appendices. A full list of references is included, as well as an author index and a subject index.

So what did they find out from their study about viewers in the 1970s? First, participants in the study watched about 1.4 hours of TV each day, which represented 6.6% of the participants' total waking hours. TV viewing was the most time-consuming activity engaged in at home, and TV viewing absorbed 40% of all leisure time, or another way to look at it, 25% of all time spent at home was spent watching TV. Ninety-three percent of TV viewing occurred in one's own home. Most viewing occurred between 7:30 and 10 PM on weekdays. Twenty percent of the time, people watched TV because they had nothing better to do, giving TV the highest nothing-better-to-do ranking of major home activities including reading, eating, cooking, chores, talking, and grooming.

People tend to watch more TV when they are in a bad mood or when they just want to relax with something mindless. When compared to work, other leisure activities, or meals, participants reported that TV required the least concentration, challenge, and skill of all, and people were most passive when watching TV than when engaging in any other leisure activity. Watching TV had the lowest mood and activation ranking of fifteen common daily activities that included such items as resting, transit, and chores. When compared to sports and other leisure activities, it was found that TV required much less concentration during the activity, and that participants found it harder to concentrate after watching TV than before they began. TV viewing is quite relaxing while participants engage in it, but once they turn the set off, they tend to feel less relaxed than when they began, which is the opposite of what happens with sports and other activities. Marketers are well aware of the fact that people watch TV for relaxation and try to keep people in front of the set by offering soothing or entertaining programs rather than material that will require concentration or upset viewers. The difficulty that people have eliminating TV viewing altogether from their lives suggests that some aspects of TV viewing may be addictive.

For the most part, I found the results of the study to be quite predictable- -we all hear from many sides that TV viewing is not good for our mental health. There were a few interesting points that Kubey and Csikszentmilhalyi uncovered that weren't fully explored, however. They note that families that watch more TV tend to get along better, and posit that one possible reason for this could be that TV watching helps to diffuse tensions, as well as provide an activity whose skill level is so low that children and adults can participate in it together. The authors note that surprisingly, the most well-adjusted teenagers have the highest levels of viewing, but they point out that teenagers with problems don't tend to spend a lot of time at home, and since most TV viewing is done in the home, there is probably no cause-and-effect link between level of adjustment and TV viewing. They note that heaviest viewers tend to be women living alone and married men living with families (married women with families give up some of their potential TV viewing time to do housework). Elsewhere in the book, they note that Blacks seem to watch more than Whites, and that viewing time increases with education. I have a hunch, however, that the most educated people in their study may have been precisely those married men whose wives were doing the housework, and that their level of education was predicted by their gender, and that their gender and family status determined how much TV they watched, not their level of education. It would have been worth it to pair up people of different family status and similar educational backgrounds to see if the observation that educated people tend to watch more TV really holds water.

By now, the data from the study are quite dated, with our cable TV possibilities far out-numbering the 3 major networks of the 1970s, as well as the advent of the Internet and development of the computer game industry to compete for leisure time with TV watching. It would be quite interesting to re-do the study in light of these developments, to see how TV relates to our leisure time and mental state today.

This is one of the most intense and empirical studies of how people relate to television (not focusing on television's content), nothing judgmental here folks, the data is presented in text and charts. We get to see the surveys, the responses, we are informed of the study methods used...

Various psychological traits are measured before, during, and after television viewing in the subjects homes. Things like concentration, cheerfulness, challenge, memory, and other traits are measured at various times using a self-reporting mechanism. The merits and faults of the methods used to study the subjects are also discussed. The book is intense.

I'm sorry I can't encapsulate it better than this. The authors (Mihaly and Robert) do an extremely admirable job of presenting the information in a readable and complete format.

Again, it should be stressed that this study was empirical. No judgements are made. Content of television was not part of the study, content of the subject's psyches was.

A landmark work.

An incredible source of insight and information even for a novice like me. The layout and flow makes this an easy read, interesting, and useful.
The insight is just what I was looking for. Thanks to the authors and editors. A great book!

"Thinking Animation" is a good overview and learning resource for anyone that wants to know how the magic of animation is made. It covers all the basic principles of animation, breaks them down and explains how they're used. It's not a step by step instruction manual of animation, though. If you're an animation student, no matter what the medium: hand drawn animation, flash animation, 3D animation, stop motion animation, etc, this book is an excellent 'text book' that covers just about everything.

This book is just fantastic, it was such a pleasure to read that I really hoped it would not end.

I found it different from other books on the subject as it gives you an overview about most processes in animation and helped me solidify some concepts that I was not sure about. It's not a technical book so don't expect step by step tutorials, which I think it's great as it wasn't intended to be. It's a book you can just enjoy on the couch with out trying to follow and press buttons.

I recommend this book to really any one who wants to have an inside look at the animation world, any one who really wants to get to grip with the terms and concepts of animation.

Best chapter was the one on acting as it really supplied some stellar advice and ideas.

I thought it was going to be Richard Williams's style book but it wasn't and in fact im kind of pleased. To me it's more like a book full of wise wisdom and tricks of the trade and really explains things in a clear cut way. If only I had this book when I first started out in the whole learning 3D thing 6 years ago this would have been my bible for deciphering most of the terms and understand what they really mean.

I really like the book has point of views from different people and how they approach their work. A really insightful book and helpful for people who have a 2D background and going to a 3D one, as there are so many terms in 3D that you don't find in 2D e.g. a graph editor and tweaking f curves. For those with a 3D background already I think book will help achieve more from their 3D animation.

This book would have really helped me a lot when I was do my dissertation called as it covers nearly every aspect I was talking about and would have saved me time, it was even helpful to see where Angie and Jamie had referenced there information from too.

All in all I think for some people as soon as they see too much text it might put them off as after all animators/creative are visual people. But on the other hand if your passionate enough and want to learn from the best or knowledge that's been past down from animator to animator its a worthy buy and for me its been a worthy buy - a book fully loaded with knowledge and wisdom, what more could you want, its like having the best animator sitting right next to you.

Being a professional animator, I was anxious to read this book. I finally got hold of a copy and was really impressed. The stage is set with a well researched history of the dynamically changing world of animation. Then the title theme comes into play in a very authoritative explanation of the art and craft of CG animation, with its roots in the traditional methods. What I liked was that the techniques discussed are not limited to any particular software package. A smart decision by the authors, as this book is not likely to ever go out of date. Adding spice throughout the book are anecdotes by various pros in the business, which are often quite humorous. THINKING ANIMATION is a must read for both practicing and armchair animators.

If you are a fan of Tomb Raider then this is the book for you. It has strategy guides for almost every Tomb Raider game ever made. Including the Game Boy Tomb Raider.

This is a pretty cool book, it has all the games rolled into one, i also really enjoyed the interviews at the end of the book.

This book is GREAT! Tomb Raider is the best game ever! I recieved my copy today and I really enjoyed it. It has everything you need to know about ALL the Tomb Raider games (except Tomb Raider 6 Angel of Darkness). It has tips on how and where the secrets are, Her moves, her enemies and how to beat the level. Also the have Tomb Raider models and an interview with Angelina Jolie! You have to order this book if you have not yet. It is a must for any collection!!

I have 3 tomb raider strategy guides from which this turned out to be the one that had everything + much more than the other two guides had. Great hints&tips, cheat codes, walkthrough, and guides on how to fight the hardest enemies, get past difficult obstacles, & where to find great secrets and how to use the most powerful weapons. Lara Croft can do anything in Tomb Raider now with the help of this great guide. The best part is that it helps you with all Tomb Raider Games not just one!

Nowadays it's almost mandatory to purchase a Prima strategy guide whenever you purchase a game. My family has been very happy with the Prima guides, and this one is no exception.

Tm 3 is da bomb!! The cars are cool, the music rocks, and I abeat the game with every driver. So go get it

This is a really good, but theoretical, in depth book on the fairly new subject of VoIP security. It is in places deep technical - not the kind of how-to-approach-the-problem type of book, but really describing in detail how things work. The reason why I picked this book was twofold. One, it really focuses on VoIP *security* - as opposed to many books on the subject that handle security or VoIP, with only one or two chapters on VoIP + security. Two, it is in-depth and detailed.

Concerning the `in-depth' part, clearly it is. The style is dense, compact, almost academic. No pages of listings or screenshots - just a factual approach: I personally hate those 800 odd pages manuals full of listings, too large font, giving the impression the author is getting paid by the page...

The objective of the book is to give a clear insight in `how it works'. It is clear that Mr. Johnston is a protocol oriented person, and quite a few things are explained and approached from that perspective. It will clearly help you in designing and architecturing a VoIP deployment, but remains theoretical. Do not expect being able to actually configure an Asterisk or other vendor product. But do expect to have a clear view on what matters and what does not, from a technical perspective. In my view, it targets solution designers, VoIP architects, to some extent the technically oriented CSO, but not so much the engineer.

Chapters 9 and 10, Signaling and Media security are really tough reading: I had to go about 2 to 3 times through them! It's not that they are not well written, but the subject is really complex, and, given the style of the book, these chapters go in quite some detail. They are followed by two interesting chapters on PSTN Gateways and Identity handling. One thing I'm missing is a chapter on Session Border Controllers - possibly these are really too new, and the authors didn't want to venture into something so new it may change and obsolete the book too quickly.

Overall, the book is well edited, with no irritating typos - as we see in too many books today. It is compact and easy to handle. Each chapter contains plenty of references to related publications: what you'd expect from any serious college textbook.

The good:
- Dense, concise, precise, detailed, complete
- Product independent - a theoretical book
- Good, no-frills publishing with no pointless screenshots and the like

The not so good
- Some parts are really hard to follow
- Nothing on Session Border Controllers, but that seems to be the only missing point.

As a CTO of a software technology company in the middle of a VOIP project, I found this book invaluable in our research. There are very few books/guides/articles that talk about VOIP security and I believe this is huge thing to consider as you launch a VOIP network in your facilities or work with the protocols. The other book I read was not nearly as technical or complete and some issues defied standard communications standards which I believe were inaccurate.

I can see from the writing that the authors bring complementary knowledge to the table. One being a data/internet security
expert who considers voice "yet another stream of data to protect" and this agnosticism is IMO a good thing because it brings voice into the IT security realm in many enterprises. The other author is a voice and VOIP standards expert so he is able to call attention to the voice and voice protocol specific issues.

The book utilizes many easy to read real world scenarios that lighten the material and distinguish it from being just a reference book on protocols and standards. These scenarios often incorporate well laid out diagrams and pictures that really help you understand what's happening.

If you are investigating or implementing VOIP networks, I definitely recommend you get this book and read it cover to cover.

I picked up this book because I needed to know a few specific things about the security of VoIP systems, and discovered that it's not only a good source of information about VoIP security - it's a good source of information about IP network security in general. We're moving all these applications to IP/Internet, and we need to know what that means for security at the IP/Internet level, not just for voice but for all of the other applications. Putting Alan Johnston, with his expertise in SIP and VoIP, with Dave Piscitello, who is an expert in security, has produced a major win. "VoIP folks" and "security folks" will both want to read this book.

VOIP - the next big thing in network communication? Or a security disaster in progress? My money's on the latter, so I was happy to be able to read through this book. It has a lot of useful background material on security and security technology, and then ties it into VOIP and the current implementations of the VOIP suite. The authors don't exactly come out and say it but the situation for VOIP looks a bit grim - security kludged on as an afterthought largely by layering atop TLS and the non-existent non-functioning public key infrastructure.

I found the book to be interesting an informative, and will recommend it as a reference to any of my friends who are so unfortunate as to have to deal with securing VOIP.

mjr.

Now, VOIP security has been talked about for a few years; it started even before organizations started to deploy VOIP in greater numbers. Many folks like to say that "VOIP security is a disaster," but usually they don't explain how or why.

Dave Piscitello does. In his excellent book ""Understanding Voice over IP Security" he provides excellent coverage of both VOIP technology basics as well as internet security fundamentals (which are admittedly more useful to the security beginners) Then he fuses the above information into a comprehensive coverage of VOIP security issues, from protocols to call fraud.

VOIP and NAT? Security analysis of SIP protocol? VOIP and honeypots? PSTN gateway security? Public VOIP vs private VOIP? Is VOIP spam inevitable? Yes, all those and much much more are covered in the book.

On the negative side, I had to skip through some of the security basics (yes, even a castle metaphor is there ...), but I am conscious of the fact that such content is indeed useful to people with networking background. At the same time, some of the esoterica of phone networks was completely new to me and thus exciting to read.

I enjoyed the book; I liked that it is written to be useful to both security folks - who need to learn about VOIP - and network folks - who often need to acquire better security education.
