CompTIA A+ Certification All-in-One Exam Guide, Sixth Edition Review

CompTIA A+ Certification All-in-One Exam Guide, Sixth Edition
Average Reviews:

(More customer reviews)
I spent over a week agonizing over which book to purchase to prepare for the A+ exam. I ended up choosing this because it seemed to me to be the most material for the money and because Meyers, the author, has a reputation for quality in the industry. After working through the book, I am fully satisfied, and passed the exam on the first try. This guide is extremely comprehensive, and laid out in a very logical and easy-to-use way. Meyers' writing style is very easy to read and engaging. Even dry subjects are quite readable. The included materials are also quite good, but I should mention a few caveats. The book advertises 8 practice exams, but that means two for each of the four tests. Because any one person will only take two tests (Essentials and one elective), there really are only four practice tests (however, there is so much overlap, I found taking all the tests to be helpful). Also, each practice test is only 50 questions, but the real test is 100, so each is only half a test. On the other hand, the practice tests are very accurate and the interface is just like what you'll face on test day. Also, if you purchase your exam vouchers from Meyers' website, you will not only save $30 on each test, but also get an additional two practice tests (100 questions) for each exam. Overall, I definitely recommend this book over any other you might be considering, and I plan to purchase the accompanying Network+ book to study for that test.

Anywhere: How Global Connectivity is Revolutionizing the Way We Do Business Review

Anywhere: How Global Connectivity is Revolutionizing the Way We Do Business
Average Reviews:

(More customer reviews)
This book hits the pluses and provides an optimistic view of emerging connectivity, but it's weak on addressing the downsides and reality of it. So, I'll begin by pointing out a few things this book overlooks. Then I'll sum up what it addresses.
What the author doesn't tell you
First, there's the productivity cost. It's huge. I used to carry a cell phone everywhere. Now, I don't use one. In fact, I rarely answer my regular telephone. Sometimes, I unplug it for hours at a time.
I don't like being interrupted, especially when I'm trying to do something productive. A business that inflicts constant connectivity on its employees has a highly distracted workforce. Ms. Green makes it sound as though the Twitter-averse among us are like the e-mail-averse of times past. But this is an apples to oranges comparison.
Second, there's the attention cost. E-mail is asynchronous. Texting and tweeting are "immediate response" activities. Can anyone who's chained to a frequently-interrupting device really pay attention to any worthwhile activity? Any technology that interrupts you simply because it can is just too costly, unless you aren't the kind of person who does anything that matters.
Third, there's the subscription cost. If you have a mobile data plan, ask yourself what you are really getting for all that money. If it's just interruptions and the ability to send/receive throwaway photos, then it might not be all that good. For a business, a mobile data plan may be essential. But how many people are paying $99 a month or more for something that they probably would not miss if they stopped using it? If you have one of these plans, is it making your life better or is it an addiction?
A fourth problem is the devices are insanely small. It's not convenient to carry around a pair of reading glasses just so you can take a phone call. I have a PocketPC that I don't use because I can't read the screen in daylight at all, and indoors I need reading glasses to read it. The manufacturer's solution to this problem was to make the next generation even smaller.
Ms. Green also indicates that older folks just don't get it and will eventually be replaced by their hipper, more tech-savvy younger counterparts through retirement. What she overlooks is the reason older people are far less adoptive of this technology than younger people is presbyopia. We have reams of data showing that humans need larger fonts as we age. That's just the way it is. When the devices are explicitly designed for people under 25 and consequently exclude people beyond a certain age, the adoption rates by age are quite predictable.
So, we have some huge barriers to "anywhere" connectivity. For the vast majority of us, it just isn't workable. Does that mean we aren't going to see vastly increased connectivity that is far more mobile than today? No. But it does mean the connectivity needs to serve the users rather than make them servile to it, and it must not rely on unreadable screens or gadgets that seem designed expressly to annoy the users. Until those requirements are met, connectivity will fall far short of its potential.
What the author does tell you
Ms. Green addresses this topic of ubiquitous connectivity in 250 pages. The book consists of four Parts:
Part I: Welcome to Anywhere. This consists of three chapters, and in these she outlines and describes the "Anywhere Revolution." I think these three chapters give the reader a good feel for where we're eventually heading and why.
Part II: The Anywhere Consumer. This consists of three chapters, and in these she presents four basic category of consumer. I'm not sure about these categories. I have fit into three of them at one time or another, and don't see where I fit presently.
I don't have her research data, but it seems to me there is a fifth category that has a higher population than the other four combined. I call it "Annoyed Consumer." We get tired of Windows memory problems, crap that pops up when you're trying to type, screens we can't read, interruptions we don't want, high bills from service providers, and just a host of usability issues. We are not amused.
Part III: The Anywhere Enterprise. This consists of two chapters. I think it needs a third. Ask hiring managers about what bugs them today, and you are going to hear "Kids texting during interviews." There is a difference between productive connectivity and counterproductive connectivity. The author doesn't explore this, at all. A chapter on how businesses can properly address this difference seems essential to me.
For example, do you really want your sales people texting during a sales call instead of focusing on that customer? Of course not. But at the same time, it would be wonderful for a sales person to be able to answer a question for the customer to close the sale. Shortening the sales cycle can accelerate revenue, and that's generally a good thing. Insulting a customer through rude behavior, however, is generally not advantageous. The rudeness factor is a big problem with today's so-called "hip generation" and it's something business needs to be able to rechannel into positive behaviors.
Part IV: Profiting from Anywhere consists of four chapters. In these chapters, the author basically says you need to max out your anywhere quotient as fast as you can. This isn't quite the way things really are. Companies that still operate on paper processes and/or have very low connectivity do need to modernize. And some companies that are current with technology, processes, and connectivity do need to be working on upgrading as the bar rises. But these are the outliers on the bell curve.
Most of us would do well to assess, based on the information presented here, and plan for staying reasonably current. I think this book is helpful toward this purpose, because it gives a good view of what is coming. But the real challenge for profit-minded businesses is going to be properly restraining connectivity to the scope of the business.
A couple of years ago, we were in the midst of blogomania. The big advice was that businesses must blog or die. Following this advice has proven to be a colossal waste of resources for most businesses, and in 2010 this realization even dawned on some business journalists. Blogs and banality have come to be synonymous, with few exceptions.
Facebook appears to have peaked out and to now be declining in its influence and popularity. People can take only so much blather, meaningless detail, and banality before wanting to have a life.
Similarly, companies can divert only so many resources to nonproductive activities before seeing their customer service, productivity, and profitability slide. The issue isn't one of having enough connectivity. It's one of having the right connectivity.
A solution seeking a problem generally does more harm than good to a business. If a business has a problem that specific types of connectivity can solve, then it needs to look at adopting those kinds of connectivity. And quickly, before the problems metastasize. But a business must also look at the potential risks involved with that adoption and develop a plan that properly addresses those risks. Otherwise, the cure might be worse than the disease.
The SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) is a core business tool for evaluating new ventures, proposed projects, and other things a business might wish to evaluate. I think if the author had used this framework for Part III and Part IV, the book would have been far more useful.
An important point the author drives at again and again is every business must look at the connectivity issues that are here now and the ones that are emerging. I think this book definitely helps identify and define many key issues in that arena.

Smart Mobs: The Next Social Revolution
Average Reviews:

(More customer reviews)


At the very end of the book, the author quotes James Madison as carved into the marble of the Library of Congress: "...a people who mean to be their own governors must arm themselves with the power which knowledge gives." And there it is--Howard Rheingold has documented the next level of the Internet, in which kids typing 60 words a minute with one thumb, "swarms" of people converging on a geospatial node guided only by their cell phones; virtual "CIAs" coming together overnight to put together massive (and accurate) analysis with which to take down a corporate or government position that is fradulent--this is the future and it is bright.
As I go back through the book picking out highlights, a few of the following serve to capture the deep rich story being told by this book--breakthroughs coming from associations of amateurs rather than industry leaders; computer-mediated trust brokers--collective action driven by reputation; detailed minute-by-minute information about behaviors of entire populations (or any segment thereof); texting as kid privacy from adult hearing; the end of the telephone number as relevant information; the marriage of geospatial and lifestyle/preference information to guide on the street behavior; the perennial problem of "free riders" and how groups can constrain them; distributed processing versus centralized corporate lawyering; locations with virtual information; shirt labels with their transportation as well as cleaning history (and videos of the sex partners?)--this is just mind-boggling.
Finally, the author deserves major credit for putting all this techno-marvel stuff into a deep sociological and cultural context. He carefully considers the major issues of privacy, control, social responsibility, and group behavior. He ends on very positive notes, but also notes that time is running out--we have to understand where all this is going, and begin to change how we invest and how we design everything from our clothing to our cities to our governments.
This is an affirming book--the people that pay taxes can still look forward to the day when they might take back control of their government and redirect benefits away from special interests and back toward the commonwealth. Smart mobs, indeed.

SIP: Understanding the Session Initiation Protocol, Second Edition Review

SIP: Understanding the Session Initiation Protocol, Second Edition
Average Reviews:

(More customer reviews)
I'm a working developer that recently became engaged in a J2EE project where needed to design and build a SIP server for a call center requiring all manner of specialized behaviors. Needless to say I needed to learn all about the ins and outs of SIP as this system would be SIP VoIP based.
I started out trying to use the various RFCs related to the SIP and SDP protocols. Well, I could spend an entire review about how miserable it is to trudge through typical RFC documentation. Online hyperlinked documentation is indeed in some respects a miracle of our modern cyber information age. Yet it's not exactly perfect. In many respects I maintain that the traditional book remains solidly the highest technological invention that mankind has yet conceived - especially now that I can compare book form information vs. its online hyperlinked and searchable alternative.
When it comes to learning and having ready access to the relevant information I'd take a book, such as "SIP: Understanding the Session Initiation Protocol" hands down vs the RFCs. I was making slow and painful progress yet once I had this book in hand, I could quickly whip around in it and cross reference the material presented in it by flipping pages, look for things via by scanning the table of contents, or dereferencing the index. Finally I started to rapidly accelerate my endeavor.
Besides the mechanics of accessing the relevant information, this book was also solidly presented by the author. He indeed has a authoritative command of the subject matter. Many of the scenarios he presents of how SIP is deployed and used were directly relevant to my particular project. It was particularly important to see the full dialog of SIP/SDP protocol exchange and the diagrams that accompanied this were very helpful. Nice visual diagrams of this manner are not to be found in the bland RFC material.
I came to amazon.com and read up on all the reviews posted for this title. Several of them gave the book a low rating. I sensed that what these people were after was a more digestible higher level presentation of the subject matter. There is an O'Reilly title on VoIP that I think might serve some of these folks better in that regard. However, this book on SIP also does a fair job of presenting SIP in light of some of the other VoIP related standards, etc. It's just that the main thrust of this book is to convey the technical understanding of SIP so that one can program systems based on it.
So if one is a software developer and needs to learn the technical ins and outs of SIP then this books is definitely the one to get. It beats using the RFCs by themselves by many leagues.

Ok, I admit I have not read it yet. But it's because I can't get my copy back! I loaned the book to the science teacher at my son's school, and asked her to take a look to see what she thought. She liked what she saw, and gave it to a 3rd grader who loves science to see if he liked it and could understand it. He did, so much so that he begged to keep it to finish! Clearly it's a hit! I bought another copy for the school to keep in the science class. And eventually, I and my 4th grader will get our copy back to read!

Their buzzes, beeps, bells, and tunes have disrupted countless classes, movies, and meals; public auditoriums now have signs posted prominently asking people to turn their cell phones off; cities such as Santa Fe have banned their use in automobiles. But these little connection gadgets have become ubiquitous because they are so useful many would blanch at the thought of losing their cell phone. Cell phones are useful because of the science, technology, and design that are blended to make them function.
In this work, authors Michele Sequeira and Michael Westphal help young people explore this now-commonplace, socially important gadget that connects today s youth with their friends. The underlying science and technologies, and some of the history that has influenced the development of cell phones, are discussed. Emphasis is given to building science and technology concepts through simple analogies with commonplace items and ideas.

New Tech, New Ties: How Mobile Communication Is Reshaping Social Cohesion Review

New Tech, New Ties: How Mobile Communication Is Reshaping Social Cohesion
Average Reviews:

(More customer reviews)
This work is honestly not for the non-academic. Rich Ling takes up an interesting question: can mediated interactions - ones that take place through some form of technology rather than face to face - have the same outcomes that we would expect from interaction ritual theory?
To begin with, one needs to understand the context of that question and what his claim - that interactions through phones (particularly cellphones) meet the criteria of interaction ritual - and know that he is engaging Randall Collins (and by extension Erving Goffman and Emile Durkheim's work on interactions) theory about what makes up a "successful interaction".
By analyzing cellphone conversations (admittedly, his methodology is a little spotty, but not to an extent that undermines his findings) Ling is able to point to how phone conversations still involved the entrainment of the participants and an emotional engagement usually thought to be the product of embodied interaction. At the very least, Ling's book points toward further research questions on how different forms of technology and media affect our social interactions and what that means for emerging social life.
i recommend this for those interested in social theory, media, and technology. i DO NOT recommend this to the casual reader unless you are looking for something completely different.

I've read a number of books on wireless security. None have made it as plain and simple as this one. Even though the title says AirPort the text covers any wireless router. The illustrations and screenshots are focused on the Mac AirPort and AirPort Express hardware, but the basics remain the same. A must buy for anyone looking for easy and practical walkthrough of basic wireless network security.

RFID Sourcebook (paperback) Review

RFID Sourcebook (paperback)
Average Reviews:

(More customer reviews)
RFID Sourcebook by Sandip Lahiri is a very well done title that you should investigate if you're starting to look into how RFID technology might be used in your organization...
Contents: Technology Overview; Advantages of the Technology; Limitations of the Technology; Application Areas; Privacy Concerns; RFID Versus Bar Code; The RFID Strategy; Creating Business Justification for RFID; Designing and Implementing an RFID Solution; Standards; Closing Thoughts; RFID Vendors, News Sources, and Conferences; Passive Tag Manufacturing Overview; Glossary; Index
I found this book to be the type that you could legitimately use in order to plan your company's approach to RFID. It's not a "rah rah" book that pretends that RFID is a panacea to all the manufacturing problems that exist. It's an even-handed coverage of the subject, and he doesn't have any qualms about covering the pros and cons that you'll have to consider if you use RFID. There's a degree of technical information in the book, but not so much that a higher-level decision maker would get bogged down in details. I guess I'd consider it more of a strategic book to make good fundamental initial decisions, and to get your project moving in the right direction early.
If RFID is something that your organization or industry is pursuing, grab this book to get grounded in the fundamentals.

RF Microelectronics (2nd Edition) (Prentice Hall Communications Engineering and Emerging Technologies Series) Review

RF Microelectronics (2nd Edition) (Prentice Hall Communications Engineering and Emerging Technologies Series)
Average Reviews:

(More customer reviews)
When I first bought this book, I was very hopeful. The book seemed to cover a lot of relevant material, in a concise fashion. When I tried to read it however, I found it a little bit too much on the concise side. I have read very complicated books with a lot of math before, and I could follow them easier than this "easy" writing style. Almost every subject is covered in other books in more detail and better. Sometimes it's nice to have a simpler book which is an introduction, and that is what I was hoping for, but this just didn't do it for me.I donated the book to the library,as I felt I would never really get too much out of it. This didn't stop me from buying Mr. Razavi's "Design of Analog CMOS ICs " and I liked his tutorial in the IEEE Phase Lock Loop book he edited.I know he can do a better job.

OFDM-Based Broadband Wireless Networks: Design and Optimization Review

OFDM-Based Broadband Wireless Networks: Design and Optimization
Average Reviews:

(More customer reviews)
I'm working on cross-layer design of OFDM based wireless system such as 802.16e and 802.11n. This book gave me a good overview of whole system from physical layer, MAC layer, to frequency planning. Basic concepts are clearly defined and key design issues are well investigated. This book is especially useful for those networking guys, like me, who want to move from networking layer down to physical layer to do cross-layer optimization. You may want to know physical layer but not every single detail. This book gives me a good abstraction of physical layer for OFDM as well as MIMO.
