Good info, numerous typos / code errors


I've been building a PIC project for three days, and after the umpteenth time looking at code in the book and realizing it can't possibly work I decided to spend the time to tell everyone interested that you can't really trust the code in the book. Its often correct, but far too often not. There is no master summary list of PIC instructions - a GLARING omission (I found one via google and printed it). I went to the author's site and McGraw-Hill's site and can't find a list of errata (which would be very long! :) It is somewhat disorganized I wound up having to flip around to get all the info on how to write interrupt routines, and now I'm doing it again for serial i/o (code for one type one place; another type another place; PIC hardware info another place; PC hardware info yet another place). While its faster to flip around a book than flip around the web via google searches, I certainly expected better. Another round of serious, competent copyediting/checking would be a very welcome improvement, as well as some reorg to have complete "framework" examples for things like serial i/o, interrupts, etc.
All this said, I'm still glad I have the book, tho it has caused some frustrating moments in the last 3 days that could have been avoided with a bit more attention on the author / mcgraw-hill's part.

Title: Complete Wireless Design
Publisher: McGraw-Hill Professional

Rating: 5/5
Customer opinion - 5 stars out of 5
Fantastic, wonderful, invaluable. Period.


At my place of work I have access to *every* RF/wireless circuit and system design book published since 1969, covering everything from books for the beginner all the way up to books for the extremely advanced RF engineer. In other words, I know what is out there when it comes to wireless circuit design books. Complete Wireless Design fills the huge gap between the cookbook/beginner style of book [which has too much missing info; neglects the disastrous RF design "gotch-yas"; and is not adaptable enough for real life design], and the advanced calculus riddled books [which can be too limited in scope; sometimes are totally incomprehensible; don't address the practical side of engineering; and rarely bother to show detailed schematics of the circuits they are so deeply discussing]. Complete Wireless Design's target is distinctly the practical, and not the theoretical [NOTE: Some university-based teachers or certain engineers may be put-off by this strongly practical, no-nonsense "let's get the circuit designed NOW!" approach, but since my own day to day work pressures force me to swiftly design RF circuits, I personally do not have a problem with this]. While no book can, obviously, be totally complete, Complete Wireless Design comes as close to this ideal as I have seen in my almost 30 years of hardcore RF circuit design experience.

statistical applications in SAS explained with examples


Brian Everitt is the author of several very well-written statistical texts. Among them he has written a number that show how to implement statistical analyses usimg statistical software packages. This second edition of "A Handbook of Statistical Analyses using SAS" he has coauthored with Geoff Der.
As a SAS user, I find this book very handy along with other similar texts that I have on the use of SAS. What is particularly good about this book is that it serves as a guide to the use of various SAS procedures and also as an illustration of appropriate statistical approaches to real applications using SAS.
It starts out with a nice introduction to the SAS prrogramming language and its syntax and progresses through simple descriptive statistics to categorical data analysis to regression and analysis of variance and then on to more advanced topics, including survival analysis, logistic regression, generalized linear models,longitudinal data analysis, principle components, factor analysis and cluster analysis. Appendices provide SAS MACROs and SAS solutions to exercises in the text.
What is particularly good about this book, that may set it apart from some of the others, is the expert statistical advice about the implementation and interpretation of results in SAS. They provide excellent scholarly references to the statistical literature to support their advice. As an example, I particularly liked their discussion of Type I and Type III sum of squares in the analysis of variance. They give a clear explanation of what each means and when they are equivalent and when they are different. In addition, they present their own view as to which is the appropriate one to use in given situations and support their view with quotes from other researchers. Opposing positions are also mentioned and referenced.

More and more relevant


We have been struggling with metadata since our first data warehouse was built. Lots of problems have been slowing this process down.
First, the definitions - not as easy as you think. We are still struggling with a "Customer" definition. Next, the source..some of our data results from many sources, some doesn't have a source. So how do we depict this? Everyone has an answer.
I started looking to books. Read data quality books, data warehousing books. Only this book takes the "metadata problem" approach.
The book is broken down into several parts. I thought some of it was beyond my understanding at first. I discussed some of the book's ideas with technical developers here, and when I went back to Part 4 (meta-meta land) and Part 5 (Sample Metadata Solutions), I understood what needs to be done in order to solve our metadata problems. I am not sure if we will ever come to terms on what is right and what is wrong, but with a "metadata solution", everyone can be happy before this decision is made.
I recommend this book to everyone that has been struggling with existing metadata. Consider the methodology depicted in this book as a way to sift through all of it. Good book, and I keep going back to it as we plan our new metadata solution approach.
