When I first heard about this book, I assumed it was about projects for speech synthesis. When I read the details on the publisher's site I was somewhat disappointed - talking meant communications in this case. However, I ordered it anyway and was quite delighted by the results. The book is well illustrated, well written, and contains 26 very interesting projects. If you are teaching networking to high schoolers or even to college students, these projects might make interesting case studies to drive home some of the points being studied.
There is one thing I would caution you on though. Don't expect the lead-you-by-the-hand electronics-heavy methodology of most other project books. This book - although apparently targeted at electronics hobbyists - goes into painstaking detail on hardware needed and assembly. However, it oddly assumes the reader doesn't need much coaching on the Processing programming language or PHP. Of course, this book would be an unwieldy tome if tutoring on those subjects were included, but just be warned that you'll need some outside sources if you are not already familiar with either of these languages. The following is the list of contents of the book along with the names and locations of the 26 included projects.

2. The Simplest Network
Project 1 - Monski Pong
Project 2 - Wireless Monski Pong

Building electronic projects that interact with the physical world is good fun. But when devices that you've built start to talk to each other, things really start to get interesting. Through a series of simple projects, you'll learn how to get your creations to communicate with one another by forming networks of smart devices that carry on conversations with you and your environment. Whether you need to plug some sensors in your home to the Internet or create a device that can interact wirelessly with other creations, Making Things Talk explains exactly what you need. This book is perfect for people with little technical training but a lot of interest. Maybe you're a science teacher who wants to show students how to monitor weather conditions at several locations at once, or a sculptor who wants to stage a room of choreographed mechanical sculptures. Making Things Talk demonstrates that once you figure out how objects communicate -- whether they're microcontroller-powered devices, email programs, or networked databases -- you can get them to interact. Each chapter in contains instructions on how to build working projects that help you do just that. You will:

Make your pet's bed send you email
Make your own seesaw game controller that communicates over the Internet
Learn how to use ZigBee and Bluetooth radios to transmit sensor data wirelessly
Set up communication between microcontrollers, personal computers, and web servers using three easy-to-program, open source environments: Arduino/Wiring, Processing, and PHP.
Write programs to send data across the Internet based on physical activity in your home, office, or backyard
And much more
With a little electronics know-how, basic (not necessarily in BASIC) programming skills, a couple of inexpensive microcontroller kits and some network modules to make them communicate using Ethernet, ZigBee, and Bluetooth, you can get started on these projects right away. With Making Things Talk, the possibilities are practically endless.

Wizard: The Life and Times of Nikola Tesla : Biography of a Genius (Citadel Press Book) Review

Wizard: The Life and Times of Nikola Tesla : Biography of a Genius (Citadel Press Book)
Average Reviews:

(More customer reviews)
Seifer's comprehensive look at Nikola Tesla is unexpected. It is neither dry, formulaic or predictable - even for those familiar with the enigmatic genius. Simply put, it is fascinating, exciting reading. Tesla was credited with the invention of modern AC power generation, remote control, fundamental advances in radio, wireless voice- and data-transfer, the first laser, advanced flight concepts, and a myriad of other inventions. Yet he died without ever achieving the financial rewards one would expect for a man who was truly ahead of his time.
Taking advantage of ill-defined intellectual property laws and the vagaries of international court systems, other well-known inventors such as Pupin, Marconi, and Steinmetz either "borrowed" his discoveries or helped write him out of the history books. While many rode Tesla's coattails to public recognition and, often, staggering financial success - the great man was left penniless and alone.
Seifer pulls no punches. Tesla made a series of startling gaffes. From ill-conceived contracts with Westinghouse (leaving him with no ongoing revenue from his discovery of the AC polyphase system) to poor management of critical projects backed by J.P. Morgan, Tesla disappointed his financiers time and time again. Lack of prioritization, spinning off in too many directions simultaneously, poor project management - all contributed to Tesla's inability to achieve the breakthrough he needed (and deserved) for true financial independence.
Seifer covers Tesla's life in exceptional detail. His bizarre work habits (often sleeping only two hours a night), his odd social life (never married and apparently a lifelong celibate), and his many other idiosyncrasies are described with fascinating anecdotes. You don't need to be an Electrical Engineer, or a Scientist, or even technically savvy to thoroughly enjoy _Wizard_. In a nutshell: superb.

CCDA 640-864 Official Cert Guide (4th Edition) Review

CCDA 640-864 Official Cert Guide (4th Edition)
Average Reviews:

(More customer reviews)
The dominant computer networking company is Cisco. So if you aspire to be a network manager, being certified in Cisco products can be an important qualification. To help you pass the CCDA DESGN exam, the authors of this book compiled a massive study aid.
Each chapter is prefaced by a 'Do I know this already' quiz. A few pages of multiple choice questions. None seems particularly hard or conceptually deep. This is a nice format for what is meant to be a purely functional, single purpose book. Perhaps like the venerable Schaum's Outline series, fleshed out with more narrative. I wonder why I don't see this more often. Often texts for exam preparation have quizzes at the end of chapters; not at the start.
As usual with most Cisco books, the network diagrams are well drawn and usually simple. An invaluable aid to understanding the accompanying narrative. Often, the diagrams reduce the discussion of a network topology or routing to the minimal essence in graphical form. This pictorial representation might be what really makes a lot of text coherent to the reader.
The book can serve another purpose. The grouping of information into the various chapters is a handy way to study networking. Several of the chapters, like those on Internet Protocol version 4 and version 6, can be regarded as quite generic; ie. not about Cisco products and their specific properties. Likewise with the chapter on managing security. This talks about 3rd party tools (think Nmap, Nessus and Kismet as examples) and the overall design of a network.
Don't forget the accompanying CD. While the book has those quizzes, the CD is meant as a full test run, after you have hopefully assimilated the chapters. If you are indeed preparing for the exam and have gotten this book, sittin thru the CD is vital feedback on your preparation status. If you find that you've scored too low on the CD exam, then consider postponing taking the real exam while you reread [more carefully this time!] the book. This can easily repay the cost of the book, compared to having to retake the exam.

Perpetual Contact: Mobile Communication, Private Talk, Public Performance Review

Perpetual Contact: Mobile Communication, Private Talk, Public Performance
Average Reviews:

(More customer reviews)
Published in 2001, this book is a collection of twenty-one papers submitted by research-oriented writers from both the academic and corporate worlds.
The papers discuss aspects of mobile voice and data communication adoption and use and the impact of this technology on various societies. Some of the papers compare the affects of mobile communications technology between cultures and nations including Scandinavia, Asia, the USA and other European nations.
Some papers relied only on the author's observations to support their thesis, and others used qualitative or quantitative consumer surveys, or statistical analysis of other published numerical data. Most were very analytic and written in the tone of professional, peer reviewed academic technical journal articles complete with extensive bibliographic references. It seems the authors were searching to construct some new models of social and cultural interaction based on the use of mobile technologies.
There are some thought-provoking analytic studies documented here, and good bibliographic references. If this is what you are looking for I feel that these papers would rank among the vanguard of social and cultural research in mobile telephony at the time.

Windows 7 Annoyances: Tips, Secrets, and Solutions Review

Windows 7 Annoyances: Tips, Secrets, and Solutions
Average Reviews:

(More customer reviews)
...or maybe after a generation of Windows operating systems, we're simply immune to assaults by Windows products on the sensibilities of computer users (especially users more interested in doing things with their data files than tweaking their operating systems).
In either case, "Windows 7 Annoyances" is less a catalog of serious Windows 7 annoyances, and more a compendium of advanced Windows 7 features, trips and tricks.
The features and solutions it offers are thorough, and described in superb technical detail. The target audience for this book is clearly power users confident in the deep (and sometimes scary) areas of Windows 7. Proof of this is found in Chapter 3, 72 pages devoted exclusively to the Windows registry. David Karp offers exhaustive descriptions and prescriptions of the Windows 7 registry. He does this very well, but in giving registry tweaks this much emphasis he is speaking to advanced power users of computers. Most Windows users are probably better served by avoiding working in the registry except for last-ditch efforts to correct their worst problems. Registry modifications bring with them the true potential to inflict serious unintended consequences to your computer, and I suggest that the book's biggest shortcoming is in not giving this potential risk enough emphasis.
Similarly, Chapter 9 is focused entirely on use of text-based command prompts. These are arguably tools of the power user looking to work faster (or deeper) than a GUI permits.
Otherwise, the book is a delightful guide to things about Windows 7 that Microsoft forgot to tell us. It describes the different versions of Windows 7, gives sound advice on making files and folders behave consistently, provides a tutorials on media files, offers troubleshooting and diagnostic tools, and walks you patiently through networking/Internet concepts and security issues.
Two appendices provide overviews of the BIOS (the basic input output system, which allows a personal computer to boot into ANY operating system), and TCP/IP, the standards that allow data to flow over the Internet regardless of the hardware and software packages that are sending and receiving them.
If you're not *seriously* annoyed by Windows 7, then this book may be more than you need, and you might want to consider Windows 7: The Missing Manual instead.
But if you're a power user and want to increase your control over Windows 7 (or if you are the go-to person for fixing the computer problems of family and friends), then this book will be a good addition to your troubleshooting toolkit.

MCITP Self-Paced Training Kit (Exam 70-685): Windows 7, Enterprise Desktop Support Technician (Pro - Certification) Review

MCITP Self-Paced Training Kit (Exam 70-685): Windows 7, Enterprise Desktop Support Technician (Pro - Certification)
Average Reviews:

(More customer reviews)
Bear in mind, I have several certifications:
I studied this book, forwards, backwards and sideways.
I understand the content, and tested repeatedly high with the enclosed test prep materials.
There is not one concept or item in this book that I do not understand.
None the less, this book did not prepare me for this exam.
The authors did a good job of covering Windows 7 in the enterprise.
There's just one problem, THIS EXAM WHICH I JUST FAILED is weighted heavily in knowledge of Windows Server 2008 R2.
The case scenarios all have at least 25 variables each, and most, if not all of those variables center around the server O.S.
Microsoft should split this exam into 2 parts. 1 part for Windows 7, and one part for Windows server.
I've never felt so cheated in my life.
--Update--
I went through this book cover to cover a second time, did all the exercises and case scenarios.
Just failed the test a second time.
I wonder if there are any stats on the pass rate for this 70-685?
Between the two failed exams and the cost of this book, I'm out about $275.00
After 17 years, I'm finished with Microsoft Press material of any kind.
The 70-680 Microsoft press book was a disaster with the sheer volume of errors. (18 full pages of errata)
This book has no bearing whatever in the actual exam that MS publishes for the 70-685.
I'll stick with Cisco, Novell and CompTIA from now on.

CNET Do-It-Yourself Laptop Projects: 24 Cool Things You Didn't Know You Could Do Review

CNET Do-It-Yourself Laptop Projects: 24 Cool Things You Didn't Know You Could Do
Average Reviews:

(More customer reviews)
I like the subtitle: 24 cool things you didn't know you could do! This book is a useful checklist of things you can do, and not just with laptops.
The first project suggests the audience: "Make a Killer Car Stereo." In other words, teens and twenty-somethings. It starts with Easy projects--fun stuff like "Make Free Phone Calls" (use Skype). Then it takes up Challenging and Advanced projects that are mostly not-fun but practical (and not so challenging), like "Protect Your Laptop from a Data Disaster" (back it up) and "Make Your Laptop Safe for Surfing" (use anti-virus and other security software). This is either padding or useful beginner's stuff, depending on how you look at it.
I bought the book for Project 7: "Transfer an LP or Cassette Tape to CD." I liked the approach: download a crippleware application, hook up the laptop to your amp, play and record, test, then decide if you want to upgrade the software to the full version. It's a good way to find out if you really want to do this stuff. (And, by the way, it's Chaka Khan, not Chaka Kahn.)
There was one problem in Project 7, though, and it foreshadowed perils to come. The note on p. 55 reads: "If you have a standalone turntable, you can't just connect it directly to the laptop. . . . Your record player is probably already hooked up to a stereo receiver or amplifier, so just connect the laptop to the receiver's RCA output jacks. Alternatively, you can get an inexpensive preamp that will do the job."
There's a better way to put this: "Almost all modern amplifier/receivers have no phono inputs at all, i.e. no built-in phono preamp. So if you're going to rip your old LPs using your old turntable, use your old amplifier/receiver, or buy a $25 preamp from Radio Shack." And this should have been on the first (project) page, so you don't gallop past it. For most interested parties, it's a constraint, not a casual comment.
The perilous projects come at the end: "Upgrade Your Operating System," "Upgrade Your Memory," "Upgrade Your Hard Drive," "Upgrade Your Processor." Yeah, you can do it. I've done some. I'm interested in doing others. But this is NOT the place to find out how.
I'm certainly interested in upgrading my hard drive, and this book tells me how to take my laptop apart sufficiently to view, remove, and replace the part. It tells me to have my Windows operating system reinstallation disks handy and to do a full backup of all my data. And it reassures me: "Once you've installed the new hard drive, you'll still be able to access your old drive using an external USB enclosure."
Frankly, I'm not greatly confident that eight pages of instructions and nine steps are going to tell me everything I need to know to expand my mission-critical laptop, especially when Step 8: "Bring Back Those Apps" tells me to "grab all those old installation CDs and reinstall all of your applications." I have good reason to expect that I will run into innumerable licensing and configuration problems, lose the old applications that I can't replace or can't afford to update, and be forced to spend loads of money for new copies of essentials.
In sum, it's a Hansel-and-Gretel story: go out for a romp in the woods, wander deep into the forest, and find a pretty gingerbread house.
