Fuzzy Thinking: The New Science of Fuzzy Logic ReviewBuddhist math? C'mon.
First, let me say that fuzzy logic and fuzzy arithmetic are great tools. They're valued parts of the 'soft logic' kit that includes probability, interval arithmetic, Bayesian and Markov networks, and lots of other good stuff. Fuzziness involves many of the formal techniques used in probability and elsewhere, and gives a useful, alternative view of the systems it addresses.
The basic fuzzy idea is that most descriptions involve shades of gray, that few systems really match the black/white, on/off, either/or duality of standard formal logic. That's fine, I can get along with that quite well.
My problem, though, is that Kosko presents the fuzzy world-view vs. the traditional or "scientific" in exactly the black and white terms that he rejects. He also argues that fuzziness describes the world more effectively than "scientific" terms, that the rules of arithmetic, probability, and calculus are just games. They are played for their internal consistency, not because differentiation or factorials occur in nature.
That's true, and as a heavy math user I know enough to distinguish my models from reality. Two facts remain, though. First, the models very often do describe reality in ways that can be checked easily enough: the bridge doesn't fall down and the TV receives its signal. Both happen because the bad old exact arithmetic has some kind of correspondence (no, I don't know what) to the real world, giving real ability to predict real results. Second, fuzzy logic and fuzzy arithmetic are themselves mathematical formalisms, games like all the others. Once you get past the gee-whiz stage, there is mathematical content as rigorous as in any other field of study. It's not either/or, it's very often a different way to interpret the same self-consistent games people have played for years. It adds interesting rules to the game.
The great thing is that you really can use the new interpretations and tools along with the old ones. Fuzziness doesn't demolish the old structures, it bolsters them and adds capacity.
And you can get all these benefits without shrink-wrapped, bite-sized pieces of Eastern philosophy.

Mastering MATLAB 7 ReviewI have been using a copy of this reference since I got started with Matlab about a year and a half ago. It is very good for beginners who need to look up how to do general tasks such as write a function using variable arguments, perform plotting, or figure out how to shoe-horn a problem into Matlab that doesn't really seem to fit the Matlab paradigm of everything being a matrix.

Analog Circuit Design: Art, Science and Personalities (EDN Series for Design Engineers) ReviewAnalysis is a science: there's a right answer out there, and we can all agree when it's found. Troubleshooting is the same way: when the broken bit is found and fixed, the circuit starts working properly.
Design, on the other hand, is an art; there's always more than one way to do it, and the individuality of the designer has a strong influence on the way the design turns out: hence "Art, Science, and Personalities".
This isn't to say that a good designer does unusual things without a good reason, or adds expensive bells and whistles because he happens to like them. What it means is that for designs that are not routine, the designer's personality has a lot to do with how it comes out.
To become an expert designer, you need a well-developed technical taste. Once you have a design that works at some level, it's that sour feeling in the back of your mouth that will tell you that it isn't right yet, that it can be simpler, cheaper, or more reliable. There aren't a lot of other sources of that information.
Arts are taught by apprenticeship. But where are you going to go to get taught this stuff nowadays? EE departments are going more and more to software, as shown by the vast number of graduate EEs who don't know which end of a soldering iron to hold. Jim Williams can't be everybody's mentor, but in this informal (and sometimes whimsical) book, he and his friends show us how the best analogue designers in the business go about things. You know what? One of the most important elements in the art of design is *play*.
Maybe listening in on these guys playing at being analogue designers isn't quite the same as sitting elbow-to-elbow with them, but it's as close as most of us are going to get, and it's terrifically valuable. I recommend this book to anyone who wants to become a better analogue designer, and who is not easily put off by whimsy in technical writing. (I find it refreshing and fun, myself.) I've owned this book for 6 or 7 years, and it's about ready to fall apart from rereading.Analog Circuit Design: Art, Science and Personalities (EDN Series for Design Engineers) OverviewThis book is far more than just another tutorial or reference guide - it's a tour through the world of analog design, combining theory and applications with the philosophies behind the design process. Readers will learn how leading analog circuit designers approach problems and how they think about solutions to those problems. They'll also learn about the `analog way' - a broad, flexible method of thinking about analog design tasks.A comprehensive and useful guide to analog theory and applications. Covers visualizing the operation of analog circuits. Looks at how to rapidly determine workable approximations of analog circuit parameters.

Practical Software Metrics for Project Management and Process Improvement ReviewI was introduced to Mr. Grady's work when I borrowed a copy of Software Metrics: Establishing a Company-Wide Program. Where that book interwove a storyline into metrics and how they support mature process improvement, this book is more like a desk reference. Mr. Grady has divided this book into two parts: tactical metrics, which are project-oriented, and strategic metrics which address process improvement.
The first part starts with a collection of practical rules of thumb for software managers. This collection of heuristics covers every phase of the development life cycle and are backed up with data gathered during 125 software projects at Hewlett-Packard. An example of one of these rules of thumb is that you will find 1 defect after software has been released into production for every 10 defects caught during testing. This, of course, is purely empirical, but is an interesting rule that I mentally filed away. Some highlights of the first part are: a good introduction to the goal-question-metric approach to determining what to measure based on your objectives, and a focus on project goals of maximizing customer satisfaction while minimizing project schedule and costs, and product defects. This is followed by chapters that address each of these goals. One of the best chapters in the first part of this book is work analysis. While I am more focused on the service delivery side of metrics (after the project has produced something that has been released into production), some of the metrics were very valuable to me - especially the ones that revolved around testing and QA.
Part 2 is squarely in my domain - production and application support, and service delivery. The best chapter, Dissecting Software Failures, was one of the most insightful descriptions of the defect life cycle I have ever read. It fully addresses defect data collection and analysis, and how to use this data to effect process and product improvement. Even better is the chapter on investing in process improvement. Here Mr. Grady gives a workable approach to using the defect data to developing a business case for process improvement. He guides you through developing a plan, selecting from among an array of solutions, and case studies.
This book is a quick read. It's main value lies in the many tables and facts provided on nearly every page. I use it as a desk reference, especially the appendices that summarize defect origins, types and modes, and metrics definitions. It spans both project and production metrics, and is as valuable to project managers as it is to application support professionals.Practical Software Metrics for Project Management and Process Improvement Overview This application-oriented bookshows how to apply proven software metrics andmethods to efficiently manage software developmentand maintenance--to help boost productivity,efficiency, and quality of software projects atevery stage of the process. Detailing practical methods throughout, the bookcovers tips to best measure and present progress,a useful model for understanding organizationlimitations, possible problems in processimprovement illustrated by examples, evidence ofwhat works and what doesn't work, and more. An ideal reference for projectmanagers and professionals responsible for processimprovement.n

Software Engineering: (Update) (8th Edition) ReviewI used this book as the text in my software engineering class in the spring semester of 2008. When I was evaluating it for potential adoption, I did not read through it in detail, I looked over the chapter titles and subtitles, read the first few chapters and examined the exercises at the end of the first few chapters. As the semester progressed, I found myself wishing I had read further into the text.
As I moved through the chapters, I found myself mentally noting over and over again that topics are repeated. When the class was over, I asked the students their opinion of the book and they were unanimous, with no prompting from me, in saying that there is a great deal of repetition after the first chapters.
I have no complaint about the quality of exposition or the coverage of software engineering in this book. My reason for not continuing to use it in future classes is solely due to my belief that the size could have been reduced from the current 840 pages to around 600 pages with no real loss of content of flow.

Beginning ASP.NET 4.0 in VB 2010 (Expert's Voice in .NET) ReviewAs an Open source enthusiast, I never thought I would look back and grab a ASP.NET book or at least be interested in one, but recently a friend of mine asked me to help him to set up a Share Point server so I had to look for all the information available in internet, sooner than later, I asked him if he wanted a different approach to his needs, meaning I could help him out putting together some Open source solutions, but nope, he did stick to his guns.
So I had to tell him that if he wanted my help he would have to buy me some books: Microsoft SharePoint: Building Office 2007 Solutions in C# 2005 and / or Beginning ASP.NET 4 in VB 2010, anyway, he ended buying me both and it's been kind of hard to drop them, specially the second.
I titled this review "A bearer of good news" for a reason: Matthew MacDonald delivers an excellent and thorough compilation of the basics and middle level of the ASP.NET language leaving almost no space covered (he would have to write another volume for that matter) and the good news are that there's another world besides the Open source(d) one, it has improved to the point of (at least) changing some people's mind about it.
There are plenty of topics that I enjoyed reading this book but the ones that I found to be really useful are: Security and Caching, I know, we'll never know for sure if there's some hacker out there who already has the code and knowledge to break the first and I also know we'll never have applications that are fast enough, but I'm obliged to say that if we follow Matthew MacDonald's advice and handy examples, we'll be set to go.
And just to assist my comments, if you have the chance to see the performance of a Liferay portal (Open source under LGPL) against a Share Point's (Microsoft), you'll see what I mean.
Beginning ASP.NET 4.0 in VB 2010 (Expert's Voice in .NET) OverviewBeginning ASP.NET 4.0 in VB 2010 follows in the footsteps of the highly successful .NET 2.0 and .NET 3.5 editions, teaching novice users how to use ASP.NET by gradually building their knowledge of the technology up in a pyramidal fashion chapter by chapter.Comprehensively revised for both ASP.NET 4.0 and the new Visual Basic 2010 language this book presents the easiest path to ASP.NET 4.0 mastery.

Texas Instruments Voyage 200 Calculator ReviewThe actual calculator itself is stunningly powerful. It is faster than the TI-92, the full keyboard makes it easier to work with than the TI-89, and the ability to solve, factor, work with imaginary numbers, give exact answers, as well as do all of these things symbolically, plus the amazing applications included (a version of Geometer's sketchpad!), make this the best calculator made by TI.
Just beware that some standardized tests and some teachers will not let you use this calculator.
The biggest drawback is the documentation that is supposed to help you utilize the power of this calculator. There really isn't any. There's a short manual that's included in the box, but it only gives you the broad overview of how to put the batteries in and how to turn it on and off.
To find any information on how to, say, type something in that you want to factor, you have to load up the cd-rom, and hunt around on that thing to find the information you want.
Why don't they include all of this documentation along with the calculator in an actual book form? (Okay, so I know the answer to that - it saves money for them.)
It's a huge hassle - if I'm at class, or work and want to be able to use some function, I have to wait to figure it out until I can get home and load up the cd-rom, find the right page, etc....not to mention that the documentation on the CD-rom isn't that helpful either. There's lots of discussion of stuff, but it is very hard to understand.
A great calculator, but awful documentation that makes learning how to use all of its powerful functions frustrating and annoying.Texas Instruments Voyage 200 Calculator OverviewTexas Instruments 200 Calculator TIVOYAGE200 Calculators
