Wicked Cool PHP
Michael J. Ross writes "Web developers familiar with a particular programming language, such as PHP, typically turn to books and forums for assistance only when they confront a specific problem that they believe has probably been encountered by many of their peers in the past, and who have published their answers in print or online. Hence the growing popularity of programming "cookbooks", which eschew flowing narratives in favor of self-contained problem descriptions and solutions. One example of a book that combines both styles is Wicked Cool PHP: Real-World Scripts That Solve Difficult Problems, by William Steinmetz with Brian Ward." Keep reading below for the rest of Michael's review. Wicked Cool PHP: Real-World Scripts That Solve Difficult Problems author William Steinmetz with Brian Ward pages 224 publisher No Starch Press rating 5/10 reviewer Michael J. Ross ISBN 978-1593271732 summary Yet another PHP book that presents a variety of topics through sample code. Published by No Starch Press on 9 February 2008, under the ISBNs 1593271735 and 978-1593271732, Wicked Cool PHP aims to provide the reader with a wide-ranging collection of complete PHP scripts and code fragments that solve specific problems frequently encountered by PHP coders. It is not intended for explaining the fundamentals of PHP, but assumes that the reader already understands the basics of the language. The book covers PHP versions 5 and 6. On the book's Web page, visitors can purchase it online, download a sample chapter (Chapter 4: Working with Forms), and download most of the sample code.
The book's material is organized into a dozen chapters, covering a range of topic areas: some simple scripts; configuring PHP; PHP security; forms; text and HTML; dates; files; user and session tracking; e-mail; images; using cURL to interact with Web services; and three intermediate projects. A brief appendix shows the MySQL commands for creating the product_info table used in many of the book's scripts. The book's back cover claims that it offers 76 scripts, but at least one section (#69) does not contain a script.
The first chapter is titled "The FAQs of Life — The Scripts Every PHP Programmer Wants (or Needs) to Know." That's quite a claim, unfulfilled by the chapter's material, which covers only seven narrow topics, such as how to include another file in a script (require_once) and how to print an array (print_r). Furthermore, there is no common theme for the scripts chosen, aside from their addressing questions that one of the authors — who is not identified — sees repeatedly in PHP forums and discussion groups. Some are extremely basic (e.g., print_r), while others address topics that are far more advanced and deserving lengthier treatment (e.g. templating your site with Smarty). That last topic would have been much better presented as an intermediate project in the book's final chapter.
Configuring PHP is an area that can prove perilous for programmers who are new to the language, and are, for whatever reason, having difficulty setting up PHP on their home Web server. For such individuals, Chapter 2 should prove quite useful, because it offers a clear overview of how they can configure their own PHP installations to match their needs. Some of the configuration advice could be a lifesaver, depending upon the reader's circumstances — such as the information on using open_basedir to limit directory access to PHP (and energetic hackers).
However, on page 20, when the authors provide advice on how the reader can find the php.ini file, they suggest that Windows users should look in "C:\php." Actually, the default installation file path is "C:\Program Files\PHP" (unless the reader has altered the value of ProgramFilesDir in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion key in their Windows Registry). They urge the reader to delete any phpinfo() script, for security reasons. But having such a script on a remote server could be quite valuable to the reader, at some point in the future; so it would be wiser to simply rename it, assuming that the reader has not allowed hackers to list file names on his or her Web server.
Several times in the book the authors advise the reader to set the error_reporting configuration option off for production servers — as well as for development servers lacking firewalls — so hackers and others do not see system information contained in error messages. But error_reporting is best used for specifying the level of error reporting, while the display_errors configuration option is best used for disabling the display of those errors to the site visitor. Errors should still be recorded in the Apache error log, so the developer can better diagnose what happened on a production site.
As with most first editions, this one contains several errata: "phpinfo()can" (page 21), "data to encrypted" (page 42), "six years" (page 55; should be 10 years, to match the code), and "timestamp() function" (page 82; should be "time() function").
In any book, a sizable number of minor flaws will prompt the careful reader to begin questioning the editing of the book. This is especially true when encountered in the first paragraph of the first page of the Introduction: "stumbled on to," which should instead be two words. But it goes beyond just issues of line editing — to a question of judgment. That very first page also contains "After you calm down," which is too flippant for what should be a professional work, as are other instances: "living hell" (page 4), "hash-ish" (page 40), and "Mac users... [like] to buy expensive gadgets for the sole purpose of looking stylish" (page 113). The authors frequently use the term "I" without specifying which author is being referred to; presumably it is the first author listed. On page 64, they state that they had previously mentioned the === operator, but I cannot find it anywhere, and neither could whoever created the book's index.
In the sample code, the authors use double quotation marks — instead of single ones — for most of the strings, few of which contain variables. This slows down the PHP interpreter by forcing it to check for variables within the strings, to be interpolated. Moreover, they are not consistent in the usage — occasionally switching over to single quotes instead, for no apparent reason. The same is true of in-line comments, which switch back and forth between Java and C styles.
The code in general is not entirely consistent throughout the book, e.g., using print() in most cases, but echo() in the remaining ones, with no explanation as to why. Perhaps this is the result of having two authors. Most HTML tag names are in lowercase, but a couple are in uppercase.
Some of the book's code appears invalid. For instance, on page 5, one of the statements (abbreviated here), echo "$row[product_name]," generates two errors: "unexpected T_ENCAPSED_AND_WHITESPACE" and "Use of undefined constant key — assumed 'product_name'." The correct code would be: echo "{$row[ 'product_name' ]}." On page 41, $cipher is set to the string "MCRYPT_SERPENT_256," which generates an error, and probably instead should be set to the constant MCRYPT_SERPENT, which works fine. $mode is set to the string "MCRYPT_MODE_CBC," but that should be a constant as well. On page 72, the regex pattern for matching HTML anchor tags does not match an entire opening tag, but just a portion of it. In the downloadable code for section #68, getpage.php fails because "<?" should be "<?php." Readers shouldn't have to debug a book's code just to get it to run without error. Did no one test the sample code before publication?! In the code for section #71, mapdemo.php generates index errors when run without any GET parameters, and does not generate a map when values are entered in the form.
Some of the code may work in certain circumstances, but not in others. For example, on page 70, the pipe character (|) is recommended as a substitute for the forward slash (/) for regex patterns containing many such slashes. But the pipe character is a very poor choice, because it has a special meaning in regex patterns, namely, as the 'or' operator, and thus cannot be used for any pattern that needs to use that operator. In section #49, calculate_time_difference() fails if one or both of the timestamps is the epoch time (time zero). In section #61, get_ip() assumes that two $_SERVER keys are set, and fails when they are not.
Some of the code works but can give beginners the wrong impression. For instance, on page 25, the authors present a configuration setting (incorrectly referred to as an "extension"): ini_set(max_execution_time, "240"). But max_execution_time is not placed in quotation marks. Even though this does not cause an error, a newbie may do the same with ini_get(), and become confused as to why PHP then (rightly) complains. (One could argue that PHP should also flag the ini_set() call as erroneous.) Section #50 could mislead newbie programmers into using that multi-line script instead of PHP's file_get_contents(). Section #51 similarly re-creates the wheel, namely, file_put_contents().
Lastly, some of the code, comments, and variable naming choices are quite puzzling. For instance, in section #30, validate_cc_number defines a variable as $false = false, but this "variable" never gets changed in the rest of the script. That is what constants are for. In the downloadable time difference scripts for Chapter 6, we find "print abs(5 — 62);" with no apparent purpose. In timediff.php, calculate_time_difference() checks for divide by zero errors for a variable that is never used as a denominator.
Unlike most computer programming books, this one has no acknowledgments of any technical reviewers. Given all of the problems in the code, it is possible that there actually were no technical reviewers, though it is difficult to imagine any reason why a publisher would choose that unwise route.
In terms of formatting of the material in the book, most of the left-hand pages (the even-numbered ones) have the page contents shifted too far to the right, almost running into the crease of the book, and leaving a glaring amount of wasted whitespace in the left-hand margin. The only exceptions are on pages 163, 164, and 172, where portions of code awkwardly jut out into the left margin.
The downloadable code archive is quite flawed, and a fair amount of the code needs to be cleaned up. For example, getpage.php contains a lot of redundant code. Much of the sample code in the book is not included in the archive; incredibly, this includes some of the largest scripts, such as the Smarty code in Chapter 1 and the credit card processing code in Chapter 4. In fact, the archive is missing the code for two entire chapters (2 and 3). Oddly enough, at least a couple scripts in the archive are not mentioned in the book. The archive needs a complete overhaul, including the cleanup or elimination of seemingly leftover scripts such as foo.php (three instances) and captcha_old.php.
On the positive side of the ledger, the book contains information that would be of interest to all levels of PHP programmers. For instance, readers who are just barely familiar with the language will benefit from the discussions concerning superglobals, form input security, date and file manipulation, and how to save user information with sessions and cookies. More advanced developers may profit from the discussions on encryption, PHPMailer, captchas, Web services, and other topics generally found later in the book.
In addition, many of the sections include a special subsection titled "What Can Go Wrong?," in which the authors consider potential problems with the code or overall approach presented in that section. Undoubtedly other technical books provide such information, interwoven with the main narrative; but explicitly identifying potential pitfalls is a worthy practice — one that we can only hope to see in other programming books in the future.
At 224 pages, it is a relatively slim volume, but contains a fair amount of useful information relative to its size — a pithiness welcome in the world of computer books. (Fortunately, the trend in the technical publishing world has shifted away from tomes sometimes exceeding 1000 pages that are padded with poorly-edited material shoveled in by multiple authors.)
Yet all in all, Wicked Cool PHP is largely disappointing. It contains no PHP scripts that could be considered "wicked cool." Moreover, the aforementioned code problems clearly call for an improved second edition, including a complete revision of the downloadable code archive. On the other hand, Wicked Cool PHP touches upon a number of key topics in PHP programming, with minimal fluff, and gets right to the point.

Regular Expression Pocket Reference
Michael J. Ross writes "When software developers need to manipulate text programmatically — such as finding all substrings within some text that match a particular pattern — the most concise and flexible solution is to use "regular expressions," which are strings of characters and symbols that can look anything but regular. Nonetheless, they can be invaluable for locating text that matches a pattern (the "expression"), and optionally replacing the matched text with new text. Regular expressions have proven so popular that they have been incorporated into most if not all major programming languages and editors, and even at least one Web server. But each one implements regular expressions in its own way — which is reason enough for programmers to appreciate the latest edition of Regular Expression Pocket Reference, by Tony Stubblebine." Read below for the rest of Michael's review. Regular Expression Pocket Reference, Second Edition author Tony Stubblebine pages 126 publisher O'Reilly Media rating 9/10 reviewer Michael J. Ross ISBN 0596514271 summary A pithy guide to regular expressions in many languages. The second edition of the book was published by O'Reilly Media on 18 July 2007, under the ISBNs 0596514271 and 978-0596514273. On the book's Web page, the publisher makes available the book's table of contents and index, as well as links for providing feedback and any errata. As of this writing, there are no unconfirmed errata (those submitted by readers but not yet checked by the author to see whether they are valid), and no confirmed ones, either. In fact, in my review of the first edition, published in 2004, it was noted that there were no unconfirmed errata, despite the book being out for some time prior to that review. The most likely explanation is that the author — in addition to any technical reviewers — did a thorough job of checking all of the regular expressions in the book, along with the sample code that make use of them. These efforts have paid off with the apparent absence of any errors in this new edition — something unseen in any other technical book with which I am familiar.
Before discussing this particular book, it may be of value to briefly discuss the essential concept of regular expressions, for the benefit of any readers who are not familiar with them. As noted earlier, a regular expression (frequently termed a "regex") is a string of characters intended for matching substrings in a block of text. A regex pattern can match literally, such as the pattern "book" matching both "book" and "bookshelf." A pattern can also use special characters and character combinations — often termed metasymbols and metasequences — such as \w to indicate a single word character (A-Z, a-z, 0-9, or '_'). Thus, the regex "b\w\wk" would match "book," but not "brook."
Here is a simple example to show the use of regexes in code, written in Perl: The statement "$text =~ m/book/;" would find the first instance of the string "book" inside the scalar variable $text, which presumably contains some text. To substitute all instances of the string with the word "publication," you could use the statement "$text =~ s/book/publication/g;" ('g' for globally search) or use "$text =~ s/bo{2}k/publication/g;". In this simplistic example, the second statement makes use of a quantifier, {2}, indicating two of the preceding letter.
These examples employ only one metacharacter (\w) and one quantifier ({2}). The total number of metacharacters, metasymbols, quantifiers, character classes, and assertions (to say nothing of capturing, clustering, and alternation) that are available, in most regex-enabled languages, is tremendous. However, the same cannot be said for the readability of all but the simplest regular expressions — especially lengthy ones not improved by whitespace and comments. As a consequence, when using regexes in their code, many programmers find themselves repeatedly consulting reference materials that do not focus on regular expressions. These resources comprise convoluted Perl books, incomplete tutorials on the Internet, and confusing discussions in technical newsgroups. For too many years, there was no published book providing the details of regexes for the various languages that utilize them, in addition to a clear explanation of how to use regexes wisely.
Fortunately, O'Reilly Media offers two titles in hopes of meeting that need: Mastering Regular Expressions, by Jeffrey Friedl, and Regular Expression Pocket Reference, by Tony Stubblebine. In several respects, the books are related — particularly in that Stubblebine bases his slender monograph upon Friedl's larger and more extensive title, justifiably characterized by Stubblebine as "the definitive work on the subject." In addition, Stubblebine's book follows the structure of Friedl's book, and contains page references to the same. Another major difference is that Regular Expression Pocket Reference is, just as the title indicates, for reference purposes only, and not intended as a tutorial.
At first glance, it is clear that Stubblebine's book packs a great deal of information into its modest 126 pages. That may partly be a result of the terseness of most, if not all, of the regular expression syntax; a metasymbol of more than two characters would be considered long-winded! Yet the high information density is likely also due to the manner in which Stubblebine has distilled the operators and rules, as well as the meaning and usage thereof, down to the bare bones. But this does not imply that the book is bereft of examples. Most of the sections contain at least one, and sometimes several, code fragments that illustrate the regex elements under discussion.
The book begins with a brief introduction to regexes and pattern matching, followed by an even briefer cookbook section, with Perl-style regexes for a dozen commonly-needed tasks, e.g., validating dates. The bulk of the book's material is divided into 11 sections, each one devoted to the usage of regexes within a particular language, application, or library: Perl 5.8, Java,.NET and C#, PHP, Python, Ruby, JavaScript, PCRE, the Apache Web server, the vi programmer's editor, and shell tools.
Each of these sections begins with a brief overview of how regexes fit into the overall language covered in that section. Following this is a subsection listing all of the supported metacharacters, with a summary of their meanings, in tabular format. In most cases, this is followed by a subsection showing the usage of those metacharacters — either in the form of operators or pattern-matching functions, depending upon how regular expressions are used within that language. Next is a subsection providing several examples, which is often the first material that most programmers turn to when trying to quickly figure out how to use one aspect of a language. Each section concludes with a short listing of other resources related to regexes for that particular language.
There are no glaring problems in this book, and I can only assume that all of the regular expressions themselves have been tested by the author and by previous readers. However, there is a minor weakness that should be pointed out, and could be corrected in the next edition. In most of the sections' examples, Stubblebine wisely formats the code so that every left brace ("{") is on the same line as the beginning of the statement that uses that brace, and each closing brace ("}") is lined up directly underneath the first character of the statement. This format saves space and makes it easier to match up the statement with its corresponding close brace. However, in the.NET / C# and PCRE library sections, the open braces consume their own lines, and also are indented inconsistently, as are the close braces, which makes the code less readable, as well as less consistent among the sections.
Some readers may fault the book's sparse index. Admittedly, an inadequate index in any sizable programming book can make it difficult if not impossible to find what one is looking for. As a result, one ends up flipping through the book's pages hoping to luckily spot the desired topic. This is the rather unpleasant method to which a reader must resort when a technical book has no index, or one that is inadequate — which is far too often the case. Stubblebine's index offers only several dozen entries for all the letters of the alphabet, and only two symbols. Some readers might demand that all of the metacharacters and metasequences be listed in the index, so they can be found even faster than otherwise. But given the large number of metacharacters and metasequences, as well as method names, module functions, and everything else relevant, creating an exhaustive index would almost double the size of the book, and be largely redundant with the language-specific sections. Within each language, there is typically a limited enough number of pages that scanning through them to find a particular topic, would not be onerous. On the other hand, some of the index's inclusions and omissions are odd. For instance, two symbols are listed, and yet no others; why bother with those two? Also, a few key concepts are missing, such as grouping and capturing.
Yet aside from these minor blemishes, Regular Expression Pocket Reference is a concise, well-written, and information-rich resource that should be kept on hand by any busy software developer.

Practical Web 2.0 Applications with PHP
Michael J. Ross writes "Web 2.0 applications and sites commonly employ a number of technologies: PHP, MySQL, XHTML, CSS, JavaScript/Ajax, microformats (standard formats for HTML data), tags (keywords for categorizing site content), and Web feeds (formatted and streamed Web content, usually in XML, such as an RSS feed). Because learning and using most of these technologies can be rather challenging to a Web developer, perhaps the best way to get started doing so is by using all of them to create a single Web-based application, with no pretense at mastering any one of them. This is the approach taken in Quentin Zervaas's book, Practical Web 2.0 Applications with PHP." Read on for the rest of Michael's review. Practical Web 2.0 Applications with PHP author Quentin Zervaas pages 569 publisher Apress rating 7/10 reviewer Michael J. Ross ISBN 1590599063 summary An example-based guide to PHP and Web 2.0 technologies. The book was published by Apress, on 20 December 2007, under the ISBNs 1590599063 and 978-1590599068. On the book's Web page, visitors can read and submit errata (apparently none, as of this writing), read the online table of contents, download Chapter 11 ("A Dynamic Image Gallery") as a PDF file, and purchase an electronic version of the book.
Given the number and complexity of the technologies discussed in the book, it is little wonder that it is 569 pages long. There is certainly a generous amount of material, and it is grouped into 14 chapters: planning and designing the sample application; application framework setup; user authentication, authorization, and management; user registration, login, and logout; Prototype and Scriptaculous; page styling using CSS; creating a blogging system; extending the blog manager; personalized user areas; Web 2.0 features (tags, Web feeds, microformats, and public profiles); the image gallery; site search functionality; integrating Google Maps; deploying and maintaining the site.
The first two chapters set the stage for the rest of the book. Chapter 1 provides a brief overview of Web 2.0, the sample Web-based application to be developed in the book, database connectivity, search engine optimization, PHPDoc, templating, and security, as well as the major features of the sample application, namely, a blog site. Chapter 2 describes how the reader can set up the application framework needed to follow along as the author explains how to build the sample application. This includes brief descriptions of how to install Apache, MySQL, PHP, and the Zend Framework. In fact, the book makes so much use of the Zend Framework that, after reading it from cover to cover, the reader will have gained a strong understanding of how some of the most popular components of that framework can be employed in their own projects. The chapter describes the file system structure the author has chosen, how to configure your Web server, how to set up the database, and how to connect to that database. It also provides an introduction to the Model-View-Controller (MVC) design pattern, as well as the Smarty template engine — both of which are used later.
While the introductory material in the first two chapters is essential — particularly to any inexperienced programmer — and generally spot on, some of the material could use a significant amount of expansion and clarification. For instance, in Chapter 2, the instructions on how to configure one's Web server, could easily prove confusing to most readers, because the author refers to the IP address 192.168.0.80, with no explanation as to what it is and how it relates to the usual local Web server address, 127.0.0.1 (localhost). His recommendation for a "hosts" file entry, "192.168.0.80 phpweb20," certainly does not help clarify matters. Furthermore, the author does not explain why "phpweb20" should be used instead of "localhost." In the subsequent discussion on virtual hosting and Linux, in a "Note," he mentions that the reader "must have previously included the NameVirtualHost 192.168.0.80 in your main Web server configuration..." In another note on the same page, he provides instructions on the PHP setup that should have been included earlier, in the section on installing PHP. In general, there are too many instances in the early chapters where key information is presented not where the reader would need it, but pages later. This can be especially exasperating to readers who are fairly new to the technologies, and are trying their best to follow the author's examples, every step of the way.
Chapter 3 discusses user authentication, authorization, and management. Unlike most PHP books, this one does not limit the reader to using MySQL as the relational database management system in conjunction with the sample application. The downloadable code for the book makes it possible for the reader to use PostgreSQL, even though the text itself focuses on MySQL. This flexibility is made possible by the author's use of the Zend_Db class. Admittedly of little significance, some of the book's SQL code looks a bit puzzling in some places. For instance, on pages 46-47, unneeded blank lines are contained within the "create table users" statement, with no reason given. Of greater importance, the chapter includes a short but valuable section describing the potential problems of date and datetime values in MySQL caused by server time zones, daylight savings, etc. — a topic well worth reading up on. The fourth chapter explores user registration, login, and logout functionality. Crucial topics such as password reset are covered, while some others, such as password strength, are not — no doubt due to space limitations.
Ajax is considered a central part of the new Web 2.0 trend, and for doing Ajax, the author recommends Scriptaculous, which is based on Prototype — both introduced in Chapter 5. The basic CSS styling of the sample application's Web pages, is covered in Chapter 6. The only flaw in the sample CSS code is that the author formats the declarations within each rule inconsistently, with some rules having multiple declarations on a single line, and others having each declaration on a separate line, which most people find easier to read and maintain. A highlight of the chapter is the author's comparison of the advantages and disadvantages to using a print-only CSS stylesheet versus a dedicated secondary print page — a topic not even seen in Web programming books that focus on design and CSS. The chapter concludes with a discussion of client-side form validation using JSON.
Chapters 7 through 13 focus much more on the sample application's functionality: implementing the user blogging system, and supplementing it with a blog manager index, Ajax capabilities, and a WYSIWYG editor (FCKeditor); creating user areas that can be customized by the users themselves; implementing the aforesaid Web 2.0 features (tags, Web feeds, microformats, and public profiles); implementing a dynamic image gallery, using GD for resizing, etc.; adding site search capabilities using Zend_Search_Lucene; incorporating Google Maps into the users' public blogs. All of these chapters are chock full of sample code, which the energetic reader may want to test out in their own development environments — particularly if they want to follow the author in creating the sample application. Fortunately, the reader will not have to waste any of that energy typing in code, because it can all be downloaded from the author's book site.
Specifically, Chapters 7 and 8 are devoted to the blogging capabilities of the sample application. While the discussion of permanent links, filtering, and the FCKeditor WYSIWYG editor may be of interest to a reader not implementing blogging themselves, the book at this point becomes more narrow in the information that it conveys — focusing even more on the code of the sample application. After reading through dozens of pages listing the code for blog entry management, readers may begin asking themselves, "Why not just use a CMS, instead of reinventing the wheel?" It should be borne in mind that the point of the book is not to advocate reinventing the wheel, but rather to show how a sturdy and reliable wheel can be built. Nonetheless, readers will need fortitude to plow through the many pages of code.
Despite the obvious expertise of the author, readers should be alert and open-minded to potential pitfalls. In the sample application's code, for generating passwords, the author uses only a hash function, md5(), despite its vulnerability to rainbow tables. The reader is advised to use an encryption function instead of — or in conjunction with — any hash function. The book contains another example of inattention to data security: In Chapter 4, as part of the user registration process, the user's password is e-mailed to the new registrant, naturally in plaintext, making it visible to anyone who intercepts the e-mail message. Years ago, all sorts of online organizations were following this lamentable practice; fortunately, "nasty grams" from security-savvy users seem to be turning the tide.
After exploring the possibilities of dynamic image galleries and Google Maps, the last chapter may appear relatively uninteresting to the reader, because it discusses application logging, error handling., and Web site deployment and maintenance, including backups. These topics may not seem too exciting, but failing to take the lessons to heart, and then experiencing a heart-stopping crisis on one's production site, will be the kind of excitement no Web programmer wants to experience.
What distinguishes this book from the majority of other PHP titles — for better or for worse — is that the author makes extensive use of specific frameworks and other tools, such as the Smarty templating engine and the Zend Framework, as well as classes that he has written, which are freely available in the source code. As a result, the value of the book to the reader is, to a certain extent, proportional to how much that reader wants to learn and possibly use those components. For example, if the reader chooses, for whatever reason, to not use the MVC design pattern and the Zend_Controller class for implementing MVC in their application, then the author's use of these will appreciably reduce the value of the book to that particular reader. In fact, given how lengthy Chapter 2 is, such a reader may mistakenly conclude that the rest of the book would be of no greater interest to them, and consequently become discouraged and quit reading. Other examples include the homebrew DatabaseObject and Profile classes, discussed in Chapter 3. Regardless, some readers may find that even if they do not use the author's chosen tools for their own applications, there is enough other programming and application-focused information that makes the book worthwhile to them. Other readers will be disappointed in the overall value of the book should they choose not to follow the author's recommended approaches. In addition, some programmers may be quite hesitant to base one of their own applications — particularly for paying clients — on classes created by a single developer, with no accompanying unit testing code to verify its soundness.
In terms of the production of the book, it is definitely up to par, with a font that is readable and yet small enough to get plenty of information on each page — in conjunction with the bottom margins being utilized better than in other books. However, at least for my particular copy of the book, several blocks of pages were cut with different widths, making it appear as if one or two blocks had become detached from the glue binding, when in fact they were all well attached. Within the binding glue, they were all attached at an equal depth, indicating that it was the cutting of the pages that caused the problem, and not how the blocks were set in the binding.
Even though some readers may find the book overly focused on particular frameworks and other tools, Practical Web 2.0 Applications with PHP is an instructive and expert demonstration of how to use PHP, MySQL, the Zend Framework, Smarty, Ajax, and other powerful technologies for creating robust Web sites.

Practical Web 2.0 Applications with PHP
Michael J. Ross writes "Web 2.0 applications and sites commonly employ a number of technologies: PHP, MySQL, XHTML, CSS, JavaScript/Ajax, microformats (standard formats for HTML data), tags (keywords for categorizing site content), and Web feeds (formatted and streamed Web content, usually in XML, such as an RSS feed). Because learning and using most of these technologies can be rather challenging to a Web developer, perhaps the best way to get started doing so is by using all of them to create a single Web-based application, with no pretense at mastering any one of them. This is the approach taken in Quentin Zervaas's book, Practical Web 2.0 Applications with PHP." Read on for the rest of Michael's review. Practical Web 2.0 Applications with PHP author Quentin Zervaas pages 569 publisher Apress rating 7/10 reviewer Michael J. Ross ISBN 1590599063 summary An example-based guide to PHP and Web 2.0 technologies. The book was published by Apress, on 20 December 2007, under the ISBNs 1590599063 and 978-1590599068. On the book's Web page, visitors can read and submit errata (apparently none, as of this writing), read the online table of contents, download Chapter 11 ("A Dynamic Image Gallery") as a PDF file, and purchase an electronic version of the book.
Given the number and complexity of the technologies discussed in the book, it is little wonder that it is 569 pages long. There is certainly a generous amount of material, and it is grouped into 14 chapters: planning and designing the sample application; application framework setup; user authentication, authorization, and management; user registration, login, and logout; Prototype and Scriptaculous; page styling using CSS; creating a blogging system; extending the blog manager; personalized user areas; Web 2.0 features (tags, Web feeds, microformats, and public profiles); the image gallery; site search functionality; integrating Google Maps; deploying and maintaining the site.
The first two chapters set the stage for the rest of the book. Chapter 1 provides a brief overview of Web 2.0, the sample Web-based application to be developed in the book, database connectivity, search engine optimization, PHPDoc, templating, and security, as well as the major features of the sample application, namely, a blog site. Chapter 2 describes how the reader can set up the application framework needed to follow along as the author explains how to build the sample application. This includes brief descriptions of how to install Apache, MySQL, PHP, and the Zend Framework. In fact, the book makes so much use of the Zend Framework that, after reading it from cover to cover, the reader will have gained a strong understanding of how some of the most popular components of that framework can be employed in their own projects. The chapter describes the file system structure the author has chosen, how to configure your Web server, how to set up the database, and how to connect to that database. It also provides an introduction to the Model-View-Controller (MVC) design pattern, as well as the Smarty template engine — both of which are used later.

Drupal 5 Themes
Michael J. Ross writes "For any Web site based upon Drupal, an increasingly popular CMS, the styling of the site is controlled by whatever Drupal "theme" has been installed, enabled, and chosen, by the site administrator. Out of the box, Drupal offers only a handful of themes, and thus site administrators oftentimes will instead opt for a theme developed by a third-party. However, if the administrator cannot find one that exactly matches their needs or those of their client, then they will either have to pay someone to custom-build a theme, or learn how to do it themselves. Fortunately, creating a new theme or modifying an existing one, is not that difficult, as demonstrated in Drupal 5 Themes, by Ric Shreves." Read below for the rest of Michael's review. Drupal 5 Themes author Ric Shreves pages 260 publisher Packt Publishing rating 6/10 reviewer Michael J. Ross ISBN 1847191827 summary A guide to modifying Drupal themes, and creating new ones. The book was published on 22 December 2007, by Packt Publishing, under the ISBNs 1847191827 and 978-1847191823. It is a slender volume, at only 260 pages, and yet covers most of the basics, in eight chapters and one appendix: the basic elements of a Drupal theme, including the files involved; finding, installing, configuring, managing, and uninstalling themes; theme engines, with a focus upon the most commonly used one, PHPTemplate; style sheets and themeable functions; overriding CSS rules, Drupal functions, and template files; modifying an existing theme, using the popular Zen theme as an example; creating a new PHPTemplate-based theme from scratch, and how to extend it; creating a theme not based upon an engine; theming Drupal forms. On the book's Web page, visitors can download most of the sample code presented in the book, send the publisher feedback, ask the publisher a question, and download a sample chapter (number 3, "Working with Theme Engines") as a PDF file.
On the positive side of the ledger, Drupal 5 Themes is a solid introduction to Drupal theming, and the author takes his time in explaining the key concepts. Extensive use is made of sample code, in addition to screenshots of themed pages, admin pages, directory trees, and more.
On the negative side of the ledger, the book contains many small errors — even for a first edition. There are far too many misspellings: "new-comer" (page 8), "where ever" (page 10), "blocks manager" (on the same page — even the same paragraph!), "in depth" (as an adjective, on pages 23 and 24), "jump start," "down side" (both on page 27), "sites" (as a possessive, page 54), "some where" (page 87), and one that undermines the technical credibility of the author, "FavIcon" (page 50). Sadly, there are numerous other errata. For instance, on page 47, we stumble over "to the tailoring an existing theme." On page 10, "assemble to core" should instead read "assemble the core." In several instances, "comprise" is mistaken for "compose." The alert reader will spot other signs of sloppy editing: One pages 18-19, the author should have chosen either "Tables Free" or "CSS-based," and be consistent. The penultimate paragraph on page 123 has double periods. The synonym of "theme" that is posited, "template," is related, but not synonymous; but the common term "skin" isn't even mentioned. On page 188, "page-blog-tpl.php" contains a typo.
Some of the author's phrasing is quite awkward, e.g., "Dev Server" (page 120) apparently means a local Web server. In fact, throughout the book he flip-flops on using lowercase or title case for such terms as "block" and "region." The overuse of title case is also found throughout the book, with some of it almost laughable, e.g., "... the Big Picture." In terms of the writing style, it could certainly be improved, such as judicious use of commas where needed — particularly in the countless run-on sentences. In general, this book contains more errata and style gaffes than any other computer book I have ever seen, on an absolute basis — even worse per page, considering it has perhaps half the number of pages of the typical computer book.
Turning to the technical material itself, there are inconsistencies as well. For instance, some URLs contain root directory slashes, while others do not. Some menu breadcrumbs use ">" as a delimiter, while others use "|." Furthermore, the Drupal menu breadcrumbs (e.g., "administer>themes") should be in sentence case, not lowercase, to match Drupal's names. Fortunately, none of the aforementioned flaws prevent the reader from understanding the book's material, but they reveal insufficient effort in the writing and editing phases, and suggest that other, less obvious, mistakes were possibly made.
In terms of the book's production, it could be improved. Some of the images are highly pixelated — especially the screenshots of directory trees. What will perhaps be most annoying to some readers, is the publisher's use of a glossy black ink that causes each page to reflect one's reading light. One might initially hope that this is an unavoidable disadvantage of the publisher perhaps choosing an environmentally friendly ink, or some similar reason, but nowhere in the book is the type or choice of ink mentioned. This suggests the poor choice was made for economic and not ecologic reasons.
The chapter summaries add nothing to the discussion, and could be removed without loss.
We now turn to specific chapters. In Chapter 2, the author discusses how to install and configure themes, and also touches upon global configuration settings, as well as module and block management. This information is put to use in the second part of the chapter, which covers the customization of Garland, the default Drupal theme. Some of the material in this chapter could prove puzzling or even misleading to many readers. The author states that enabling a theme and setting it as the default, applies it to "both front end and back end of the site" (page 31). Actually, it only changes the front-end theme; the back-end theme is set via Administer > Site configuration > Administration theme; oddly, he actually acknowledges this much later. In the theme configuration screenshots in Chapter 2, the "gagarin" theme is missing, even though it was supposedly installed earlier. On page 40, the author instructs, "To access all the user permissions and configuration screens in one place, view your administrator console by module." But Administer > Site building > Modules is not where the administrator sets user permissions and blog configurations. In the discussion of page specific visibility settings, the third radio button option (entering PHP code to control the visibility of the block) is only displayed if the user has enabled "use PHP for block visibility" in Administer > User management > Access control. The figure caption on page 50 could give a reader the mistaken idea that Drupal renames the custom logo image to "garland_logo.gif" automatically, prior to the configuration settings being saved, which is mentioned afterwards. On page 58, the illustration shows PHP code that appears to contain an extraneous tag, , which is probably a holdover from the illustration on page 56; in fact, it breaks the code, because the presence of that string always effectively returns TRUE. On pages 86 and 87, the PHP code contains four back ticks, which should be replaced with straight apostrophes.
Theme engines, specifically PHPTemplate, is explored in Chapter 3. The author explains the primary functionality of the six files that constitute this built-in theme engine. These are illustrated by comparing two PHPTemplate themes — Garland versus Gagarin. The chapter concludes with brief overviews of three other theme engines, PHPTAL, Smarty, and PHP XTemplate.
Modifying a theme to customize a Drupal site, can be done in one of two ways, or a combination of the two, which is the typical approach: overriding default CSS rules, and overriding themeable functions. Chapters 4 and 5 explain how to do so, with the former containing a list of themeable functions organized by functionality. Chapter 5 covers the details of overriding Drupal CSS and functions, including a valuable discussion of the various options open to the developer for overriding functions, including step-by-step instructions. The chapter concludes with a brief explanation as to how to intercept template files.
Chapters 6 and 7 form the heart of the book, because they explain the details of modifying an existing theme and building a new one from scratch. Anyone interested in learning how to style their Drupal-based Web site with maximum flexibility, will find these two chapters of value. However, there are several pitfalls the reader will want to watch for: Early in Chapter 6, the author instructs the reader who is following along to rename the theme-specific functions in the template.php file from "zen_" to "tao_." Yet this is insufficient, because the page formatting for this new theme, tao, already differs from Zen's. This is likely due to the theme PHP files not finding one or more CSS files that still contain the name "zen." In fact, to completely replace the old theme name throughout Zen's code, one needs to change nine other PHP files. In the section describing how to set up the menus, the weights for the "Home" and "Contact Us" links are supposedly set to 10 and -10, respectively, which would place the former to the left of the latter; yet the illustration on page 148 shows the opposite. The "Blog Entries" weight should be -10 instead of 10. The weights for the footer navigation menu links appear to be equally messed up. In addition, both instances of "yourdomain" is followed by an erroneous space. Frankly, it is as if the book had never been technically edited.
Chapter 7, the longest in the book, is possibly the one that will receive the most study by readers who wish to learn the intricacies of making their own theme from the ground up. The author provides a step-by-step explanation as to what is involved in creating a new theme, and the advantages and disadvantages to alternative approaches. He uses a sample theme, "Bluewater," to illustrate the ideas. The problems with this material are fairly minor: The diagram caption on page 152 states that the elements within the CSS are ordered alphabetically, and yet no alphabetical ordering is apparent. In fact, the ordering doesn't even match that in the page.tpl.php file. In addition, page.tpl.php contains a couple curly quotes, though this does not affect its functionality. Aside from these issues, the discussion is quite thorough, and the reader ends up with a fully functional — though not especially attractive — Drupal theme. The chapter concludes with coverage of template variables, the use of multiple templates, dynamic theming, and developing a theme without the use of any theme engine. However, on page 188, the author states where you can find an example page but there's almost nothing on that page — as of this writing — aside from links to pornographic photos and video. Did the author intend for readers to find them? Either way, it signifies poor judgment on the part of the author.
For many PHP developers, working with form pages is oftentimes the most problematic part of creating a Web site. Fortunately, this book tackles the topic, in Chapter 8, as it pertains to Drupal sites.
In spite of the terribly sloppy writing and editing (both narrative and technical), Drupal developers interested in creating their own themes, or modifying those created by other developers, will find straightforward and detailed coverage in Drupal 5 Themes.

Sadly, there are numerous other errata. For instance, on page 47, we stumble over "to the tailoring an existing theme." On page 10, "assemble to core" should instead read "assemble the core." In several instances, "comprise" is mistaken for "compose." The alert reader will spot other signs of sloppy editing: One pages 18-19, the author should have chosen either "Tables Free" or "CSS-based," and be consistent. The penultimate paragraph on page 123 has double periods. The synonym of "theme" that is posited, "template," is related, but not synonymous; but the common term "skin" isn't even mentioned. On page 188, "page-blog-tpl.php" contains a typo.
Some of the author's phrasing is quite awkward, e.g., "Dev Server" (page 120) apparently means a local Web server. In fact, throughout the book he flip-flops on using lowercase or title case for such terms as "block" and "region." The overuse of title case is also found throughout the book, with some of it almost laughable, e.g., "... the Big Picture." In terms of the writing style, it could certainly be improved, such as judicious use of commas where needed — particularly in the countless run-on sentences. In general, this book contains more errata and style gaffes than any other computer book I have ever seen, on an absolute basis — even worse per page, considering it has perhaps half the number of pages of the typical computer book.
Turning to the technical material itself, there are inconsistencies as well. For instance, some URLs contain root directory slashes, while others do not. Some menu breadcrumbs use ">" as a delimiter, while others use "|." Furthermore, the Drupal menu breadcrumbs (e.g., "administer>themes") should be in sentence case, not lowercase, to match Drupal's names. Fortunately, none of the aforementioned flaws prevent the reader from understanding the book's material, but they reveal insufficient effort in the writing and editing phases, and suggest that other, less obvious, mistakes were possibly made.
In terms of the book's production, it could be improved. Some of the images are highly pixelated — especially the screenshots of directory trees. What will perhaps be most annoying to some readers, is the publisher's use of a glossy black ink that causes each page to reflect one's reading light. One might initially hope that this is an unavoidable disadvantage of the publisher perhaps choosing an environmentally friendly ink, or some similar reason, but nowhere in the book is the type or choice of ink mentioned. This suggests the poor choice was made for economic and not ecologic reasons.
The chapter summaries add nothing to the discussion, and could be removed without loss.
We now turn to specific chapters. In Chapter 2, the author discusses how to install and configure themes, and also touches upon global configuration settings, as well as module and block management. This information is put to use in the second part of the chapter, which covers the customization of Garland, the default Drupal theme. Some of the material in this chapter could prove puzzling or even misleading to many readers. The author states that enabling a theme and setting it as the default, applies it to "both front end and back end of the site" (page 31). Actually, it only changes the front-end theme; the back-end theme is set via Administer > Site configuration > Administration theme; oddly, he actually acknowledges this much later. In the theme configuration screenshots in Chapter 2, the "gagarin" theme is missing, even though it was supposedly installed earlier. On page 40, the author instructs, "To access all the user permissions and configuration screens in one place, view your administrator console by module." But Administer > Site building > Modules is not where the administrator sets user permissions and blog configurations. In the discussion of page specific visibility settings, the third radio button option (entering PHP code to control the visibility of the block) is only displayed if the user has enabled "use PHP for block visibility" in Administer > User management > Access control. The figure caption on page 50 could give a reader the mistaken idea that Drupal renames the custom logo image to "garland_logo.gif" automatically, prior to the configuration settings being saved, which is mentioned afterwards. On page 58, the illustration shows PHP code that appears to contain an extraneous tag, , which is probably a holdover from the illustration on page 56; in fact, it breaks the code, because the presence of that string always effectively returns TRUE. On pages 86 and 87, the PHP code contains four back ticks, which should be replaced with straight apostrophes.
Theme engines, specifically PHPTemplate, is explored in Chapter 3. The author explains the primary functionality of the six files that constitute this built-in theme engine. These are illustrated by comparing two PHPTemplate themes — Garland versus Gagarin. The chapter concludes with brief overviews of three other theme engines, PHPTAL, Smarty, and PHP XTemplate.
Modifying a theme to customize a Drupal site, can be done in one of two ways, or a combination of the two, which is the typical approach: overriding default CSS rules, and overriding themeable functions. Chapters 4 and 5 explain how to do so, with the former containing a list of themeable functions organized by functionality. Chapter 5 covers the details of overriding Drupal CSS and functions, including a valuable discussion of the various options open to the developer for overriding functions, including step-by-step instructions. The chapter concludes with a brief explanation as to how to intercept template files.
Chapters 6 and 7 form the heart of the book, because they explain the details of modifying an existing theme and building a new one from scratch. Anyone interested in learning how to style their Drupal-based Web site with maximum flexibility, will find these two chapters of value. However, there are several pitfalls the reader will want to watch for: Early in Chapter 6, the author instructs the reader who is following along to rename the theme-specific functions in the template.php file from "zen_" to "tao_." Yet this is insufficient, because the page formatting for this new theme, tao, already differs from Zen's. This is likely due to the theme PHP files not finding one or more CSS files that still contain the name "zen." In fact, to completely replace the old theme name throughout Zen's code, one needs to change nine other PHP files. In the section describing how to set up the menus, the weights for the "Home" and "Contact Us" links are supposedly set to 10 and -10, respectively, which would place the former to the left of the latter; yet the illustration on page 148 shows the opposite. The "Blog Entries" weight should be -10 instead of 10. The weights for the footer navigation menu links appear to be equally messed up. In addition, both instances of "yourdomain" is followed by an erroneous space. Frankly, it is as if the book had never been technically edited.
Chapter 7, the longest in the book, is possibly the one that will receive the most study by readers who wish to learn the intricacies of making their own theme from the ground up. The author provides a step-by-step explanation as to what is involved in creating a new theme, and the advantages and disadvantages to alternative approaches. He uses a sample theme, "Bluewater," to illustrate the ideas. The problems with this material are fairly minor: The diagram caption on page 152 states that the elements within the CSS are ordered alphabetically, and yet no alphabetical ordering is apparent. In fact, the ordering doesn't even match that in the page.tpl.php file. In addition, page.tpl.php contains a couple curly quotes, though this does not affect its functionality. Aside from these issues, the discussion is quite thorough, and the reader ends up with a fully functional — though not especially attractive — Drupal theme. The chapter concludes with coverage of template variables, the use of multiple templates, dynamic theming, and developing a theme without the use of any theme engine. However, on page 188, the author states where you can find an example page but there's almost nothing on that page — as of this writing — aside from links to pornographic photos and video. Did the author intend for readers to find them? Either way, it signifies poor judgment on the part of the author.
For many PHP developers, working with form pages is oftentimes the most problematic part of creating a Web site. Fortunately, this book tackles the topic, in Chapter 8, as it pertains to Drupal sites.
In spite of the terribly sloppy writing and editing (both narrative and technical), Drupal developers interested in creating their own themes, or modifying those created by other developers, will find straightforward and detailed coverage in Drupal 5 Themes.

PHP In Action: Objects, Design, Agility
Michael J. Ross writes "Despite being perhaps the most popular Web language in use, PHP has for much of its history been criticized for not offering the full capabilities of object-oriented programming (OOP). But with the release of version 5, PHP introduced a robust object model, and made it easier for its proponents to create well-architected Web sites and applications. In turn, the new OOP capabilities have facilitated additional best practices, such as design patterns, test-driven development, continual refactoring, and HTML templates. These topics and more are explored in the book PHP in Action: Objects, Design, Agility." PHP in Action: Objects, Design, Agility author Dagfinn Reiersol, Marcus Baker, Chris Shiflett pages 552 publisher Manning Publications rating 8/10 reviewer Michael J. Ross ISBN 1932394753 summary A pragmatic guide to object-oriented PHP development. Authored by Dagfinn Reiersøl, with Marcus Baker and Chris Shiflett, the book was published on 3 July 2007 by Manning Publications, under the ISBNs 1932394753 and 978-1932394757. Its subtitle accurately reflects the major themes of the work: creating PHP applications built upon objects, utilizing Web-oriented design patterns, and incorporating agile programming techniques such as refactoring and test-driven development. Also covered are methods for effective form handling, database extraction, date and time representation, and more.
As a result of trying to adequately cover such a large number of major topics in a single book, the amount of material is considerable, and the book is certainly longer than the typical Web programming book in general, and PHP book in particular. Spanning 552 pages, the material is organized into 21 chapters, grouped into four parts: In Part 1 ("Tools and concepts"), the authors discuss PHP 5, its strengths and weaknesses, and how well it can be used with advanced programming principles; an overview of objects, exception handling, and references; visibility, abstract classes, and interfaces; effective use of classes and object-oriented design; inheritance, composition, and more on interfaces; advanced object-oriented principles; six design patterns that are especially appropriate for Web-based systems (Strategy, Adapter, Decorator, Null Object, Iterator, and Composite); and lastly, date and time handling using objects.
For developers well-versed in OOP, Part 1 may be more of a review, while Part 2 ("Testing and refactoring") could be the most valuable portion of the book. In the four chapters, the authors dig into the details of test-driven programming, refactoring, and Web testing. These chapters and all that follow take a very pragmatic approach to conveying ideas, which is consistent with the theme of Manning's "In Action" series, based upon the idea that programmers tend to learn best by reading sample code instead of generic discussion. For instance, test-driven development (TDD) is demonstrated by showing how to implement database transactions, a contact manager, and e-mail functionality. Mock objects and top-down testing are illustrated through the creation of an e-mail class, and further extended with a discussion of faking the mail server. Given that testing is the primary theme of the entire part, one might expect a more lengthy discussion of TDD, but Reiersøl correctly notes that this particular book is not trying to replace the many manuscripts and articles already published on agile development; also, the database examples adequately demonstrate the general principles discussed prior. The chapter on refactoring is well worth reading, and touches upon the controversial topic of how much one's PHP code should be separated from the HTML code — a topic later revisited in the chapter on templates. Also explored is a topic critical to maintenance programmers — refactoring versus rewriting. Two different testing frameworks are discussed, PHPUnit and SimpleTest; the latter is used throughout the book. The final chapter in this part explains how to test Web pages programmatically, by faking interaction, and other techniques. The chapter ends with a section providing steps on how to deal with "the horror of legacy code," when the unfortunate programmer has inherited a nightmare of a live Web site.
The third part of the book, "Building the web interface," begins with an examination of templates, the arguments for and against them, and three of the most commonly used template engines: Smarty, PHPTAL, and XSLT. One of the previously discussed design patterns, Composite, is utilized for combining templates to create complex Web pages. The chapter on user interaction makes use of the Model-View-Controller architecture, with the subsequent chapter delving deeper into the topic of controllers for Web pages. The next two chapters cover an area of site development that is a frequent cause of uncertainty, "bandage coding," and security risks: user forms and input validation. The book's coverage of the PEAR package HTML_QuickForm, alone makes it worth reading. Part 3 concludes with a chapter on abstracting database resources through objects and the Singleton pattern.
The fourth and last part of the book ("Databases and infrastructure") is relatively brief, comprising two chapters on marrying SQL with object orientation. The authors present a number of techniques for shoehorning SQL transactions into object-based code, including encapsulating queries inside of methods, building SQL statements dynamically, substituting SQL elements such as column and table names, using SQL aliases, and using SqlGenerator.
It is clear that the lead author, Dagfinn Reiersøl, has put a tremendous amount of time (three years, as noted in the preface) and effort into creating this work. The discussions are wide-ranging and in-depth, and there is just enough sample code to illustrate the ideas being discussed and also break up the visual monotony. The illustrations are limited in number, and consist mostly of class diagrams and UML sequence diagrams. Overall, the treatment of each topic clearly reveals that he has considerable experience with them, and has given thought to the pros and cons of some possible approaches, though not all of them.
However, there are still some weaknesses in the book. For example, in all of the material discussing how to separate the SQL code from the PHP code, I found no mention of stored procedures, such as those made possible in MySQL. All of the sample code appeared to be solid, though there was no clear reason for the inconsistent use of print() versus echo() is different code samples. All of the chapter summaries could be excised without any loss of value, and many of the chapter introductions could be eliminated as well or condensed.
On a more mechanical level, the book had many minor weaknesses: It was not encouraging to see the first erratum even before reaching page 1: "raising own level" on page xix, in the second paragraph. Readers may initially be confused by such attributions as "Uncle Bob [Uncle Bob]" (on page 77). In a future edition, it should be explained that names in square brackets are biographical references listed in the Resources section, which follows Appendix B. In the first sentence in Chapter 12, the reference to "Jackass" will probably be confusing to many readers — particularly non-Americans — and is not in the best of taste. In the text and the table of contents, the chapter and part titles are written in sentence case, instead of title case, for no obvious reason. It is not clear whether this is meant as an unsuccessful attempt at literary hipness, or just an unfortunate reflection of the current text messaging generation, which is eschewing rules of grammar that for centuries have made text easier to read. Finally, there was one problem in the production of the book, and not its writing: Several of the pages had light brown spots on them that were apparently part of the paper, and not a result of post-production staining. But these may be limited to my particular (brand-new) copy of the book.
Readers interested in learning more about the book could start at the publisher's Web page, which features an online table of contents and index, all of the book's source code, two sample chapters (7 and 21) in PDF format, and a link for purchasing the electronic version of the book, also as a PDF file. Any road/code warriors who do development on their laptops, on the go, will appreciate having this book readily available.
Yet most of these objections are minor and easily fixable, and do not detract from the value of this book. I especially liked the depth of experience brought to each topic, and the authors' consideration of differing viewpoints. PHP in Action is a competent, engaging, and detailed discussion of object-oriented and agile programming principles that can help PHP developers boost their effectiveness and the quality of their code.

CSS Pocket Reference
Michael J. Ross writes "For Web developers who appreciate the value of separating Web content from its presentation, Cascading Style Sheets (CSS) has proved a godsend, because it allows all of the styling of a Web site to be organized in CSS files separate from the site's semantic content, in HTML files (possibly dynamically generated). Yet to make this styling power possible, CSS must incorporate a long list of syntax elements, including hundreds of selectors, properties, and values. Thus it can be quite handy for the developer to have on hand a concise summary of CSS, such as the CSS Pocket Reference, authored by Eric A. Meyer." Read on for the rest of Michael's review. CSS Pocket Reference, 3rd Edition author Eric A. Meyer pages 168 publisher O'Reilly Media rating 8/10 reviewer Michael J. Ross ISBN 0596515057 summary A concise reference book for CSS. The book was published by O'Reilly Media on 5 October 2007, under the ISBNs 0596515057 and 978-0596515058. CSS itself has evolved along with other Web technologies, and this book is now in its third edition, having been updated to reflect the ongoing changes in CSS; the book now covers CSS2 and CSS2.1. On the book's Web page, O'Reilly offers an online table of contents, as well as ways for the visitor to view and submit errata (none as of this writing) and reviews for the book. Unlike most technical publishers, O'Reilly now makes available previews of their books' contents, in the form of a table of contents with links to the first few paragraphs of each section, including tables and illustrations.
Despite the growth in the number of elements in CSS, and the attention paid to each one of them by the author of CSS Pocket Reference, the book is still small enough to fit in a pocket, at only 168 pages. The book's material is organized into 18 unnumbered sections, preceded by some notes on the book's typographical conventions, and followed by an essential index. The bulk of the material is found in the Property Reference section. Other sections explain how to add styles to HTML and XHTML pages; CSS rule structure and style precedence, including inheritance and the cascade; element classification and display roles; visual layout; rules on floating and positioning; and table layout. Subsequent sections cover CSS value types and units, and selectors, including some of the newest additions to CSS, such as the adjacent sibling selector and the language attribute selector. Just before getting into the details on properties, Eric Meyer discusses pseudo-classes and pseudo-elements, which have made it possible for Web developers to create rather robust and attractive site navigation using CSS exclusively, without any need to resort to images and JavaScript for rollover effects and other navigation eye candy.
For each element of CSS that is covered in all of the sections mentioned above, the types of information presented to the reader can vary, depending upon the category of element. But they generally include the element's possible values, a default value, what elements it can apply to, whether it is inherited, its computed value, a brief description of the element, at least one example illustrating its usage, what browsers support it, and oftentimes a note on its usage. Consequently, this new edition of the book, like its predecessors, should prove more than adequate for most CSS reference needs.
As with any computer book, there are several ways in which this one could be improved. Any reader using the book to look up a particular element, has two possible ways of doing so: They could first consult the index, and, assuming the element is listed there, go straight to the page indicated. But most readers, knowing that the elements in each section are listed alphabetically, will probably open up the book near the front or the back, and begin flipping backward or forward, respectively, hoping to spot the element of interest as quickly as possible, given its alphabetical ordering. That individual will likely immediately spot an obvious problem with the book: The pages have no running titles (the words that indicate the first element discussed on that page, and typically listed at the very top of each page). Inclusion of such running titles in the next edition of the book, would make it much faster to use.
Another valuable addition would be some sort of table listing all of the CSS elements and their level of support within the most commonly used Web browsers and, in the case of Internet Explorer, the most commonly used versions of the browser. Also, on page 48 of the book, at the beginning of the Property Reference section, it has a subhead of "Visual Media," which suggests that there are other subheads within that section, for other media types; but I was unable to find any.
All of these problems concern the publisher's choice of material. My last criticism concerns the layout of that material in the print version of the book. Because this diminutive volume has narrow pages, and they are tightly glued together in the binding, it is imperative that the publisher of such a book provide plenty of white space in the inner margins (those closest to the binding), so the reader does not have to crack open the book too much in order to read the text closest to the binding. Repeatedly opening up the book far enough to read those inmost words, will over time weaken and eventually destroy the binding. In contrast, a small reference book like this has no need for much outer margin. Sadly, O'Reilly got it backwards with this volume, with relatively wide and useless outer margins, and inadequate inner margins.
Aside from the aforementioned flaws — all of which can be remedied in the future — CSS Pocket Reference is a compact and neatly organized gem of a book, packed with information of value to busy Web programmers.

But they generally include the element's possible values, a default value, what elements it can apply to, whether it is inherited, its computed value, a brief description of the element, at least one example illustrating its usage, what browsers support it, and oftentimes a note on its usage. Consequently, this new edition of the book, like its predecessors, should prove more than adequate for most CSS reference needs.
As with any computer book, there are several ways in which this one could be improved. Any reader using the book to look up a particular element, has two possible ways of doing so: They could first consult the index, and, assuming the element is listed there, go straight to the page indicated. But most readers, knowing that the elements in each section are listed alphabetically, will probably open up the book near the front or the back, and begin flipping backward or forward, respectively, hoping to spot the element of interest as quickly as possible, given its alphabetical ordering. That individual will likely immediately spot an obvious problem with the book: The pages have no running titles (the words that indicate the first element discussed on that page, and typically listed at the very top of each page). Inclusion of such running titles in the next edition of the book, would make it much faster to use.
Another valuable addition would be some sort of table listing all of the CSS elements and their level of support within the most commonly used Web browsers and, in the case of Internet Explorer, the most commonly used versions of the browser. Also, on page 48 of the book, at the beginning of the Property Reference section, it has a subhead of "Visual Media," which suggests that there are other subheads within that section, for other media types; but I was unable to find any.
All of these problems concern the publisher's choice of material. My last criticism concerns the layout of that material in the print version of the book. Because this diminutive volume has narrow pages, and they are tightly glued together in the binding, it is imperative that the publisher of such a book provide plenty of white space in the inner margins (those closest to the binding), so the reader does not have to crack open the book too much in order to read the text closest to the binding. Repeatedly opening up the book far enough to read those inmost words, will over time weaken and eventually destroy the binding. In contrast, a small reference book like this has no need for much outer margin. Sadly, O'Reilly got it backwards with this volume, with relatively wide and useless outer margins, and inadequate inner margins.
Aside from the aforementioned flaws — all of which can be remedied in the future — CSS Pocket Reference is a compact and neatly organized gem of a book, packed with information of value to busy Web programmers.

The PHP Anthology 2nd Edition
Michael J. Ross writes "When veteran PHP developers have specific and nontrivial functionality that they want to implement in their code, they can do so from scratch, but this can be time-consuming or essentially reinventing the wheel. They can adopt completed code posted in an online discussion forum, but such code tends to be buggy. They can use an open source library or other packaged code, but this approach can oftentimes prove to be overkill. Consequently, many developers prefer focused solutions found in PHP cookbooks, such as The PHP Anthology: 101 Essential Tips, Tricks & Hacks." Read on for the rest of Michael's review. The PHP Anthology: 101 Essential Tips, Tricks & Hacks, 2nd Edition author Davey Shafik, Matthew O'Phinney, Ligaya Turmelle, Harry Fuecks, and Ben Balbo pages 542 publisher SitePoint rating 9/10 reviewer Michael J. Ross ISBN 0975841998 summary A tasty cookbook of PHP recipes The second edition of this book was published by SitePoint on 23 October 2007, under the ISBNs 0975841998 and 978-0975841990. On the book's Web page, the publisher makes available an overview of the book, links to the authors' sites, chapter descriptions, the table of contents, the index, editorial and customer reviews, the book's sample code, and errata (there are none as of this writing). In addition, there is a link for downloading three sample chapters (2, 10, and 11), in PDF format. The pop-up window for entering an e-mail address for receiving the download link, also gives one a chance to subscribe to SitePoint's Web development newsletters.
All of the authors of The PHP Anthology — Davey Shafik, Matthew O'Phinney, Ligaya Turmelle, Harry Fuecks, and Ben Balbo — appear to have plenty of experience with the language, and probably also have spent time interacting with other PHP programmers in online forums, including SitePoint's own PHP forum. Experience reading the questions posted by programmers of all skill levels, and especially trying to answer them, can give anyone a better understanding of what are the most common challenges encountered by the typical PHP coder. In the book's preface, the authors note that, for choosing the particular problems for their book, they chose ones frequently seen in the SitePoint forum, which is likely representative of all active PHP forums.
This new edition of the book has been updated for PHP version 5, including PHP's major improvements to its implementation of classes and objects, among other aspects of the language. It is one of a growing number of PHP books that depart from the traditional tutorial and reference formats, and is instead written in the increasingly popular "cookbook style." Each section presents first a common problem that Web programmers often encounter, followed by generally complete source code that solves the problem, and commentary that explains the overall solution, along with special considerations that the programmer should watch out for in adapting the given source code to their own situation.
As seen in the majority of cookbook-style programming books, this one groups the problem-and-solution sections into chapters, of which there are 13: an introduction; working with databases using the PHP Data Objects (PDO) extension; strings; dates and times; forms, tables, and clean URLs; files; e-mail; digital images; error handling; access control; client- and server-side caching; XML and Web services; PHP coding best practices. In addition to the preface and index, the book also has four appendices: configuring PHP; a checklist for choosing a Web hosting service; a security checklist; and working with the PHP Extension and Application Repository (PEAR). In total, the book is 542 pages long, and yet it is not visually overwhelming, partly because of the large and readable font chosen by the publisher, as well as the innumerable code snippets and browser screen shots interspersed throughout the narrative.
The primary strength of this book is the significant amount of information provided to the reader, in the form of summaries of critical Web programming problems, working PHP code that addresses those problems, discussion as to why each particular approach was taken, and occasional asides that warn the reader about special difficulties that they might encounter as they implement the solutions within their own development environments and for their own projects. Some of the material may be of little interest to the average reader — such as the chapters on PDO and XML — but most of the material would be of interest and benefit to any conscientious PHP programmer. The chapters on error handling and access control are alone worth the price of the book.
However, this second edition of the book has some weaknesses that may or may not have been introduced since the first edition (which was not readily available for comparison). But none of them are overwhelming or unfixable. Firstly, a reader hoping for a well-edited book will likely become distrustful by the authors' misuse of the term "that" in place of "who." Secondly, there are far too many ambiguous comments in the first-person, e.g., "I would dare to say that..." In a book written by five authors, the reader naturally has no idea who is speaking. Thirdly, there is a fair amount of inconsistency in the formatting of the code throughout the book, including indentation and other spacing, as well as variable naming. Also, every instance of a "{" on its own line (presumably to line up vertically with the corresponding "}"), is an antiquated waste of space, since any decent programmer's editor or integrated development environment (IDE) can do brace matching automatically.
Lastly, almost all of the section titles begin with the phrase "How do I." That is fine within the body of the book, at the beginning of every section. But when dozens of these section titles are listed together in the table of contents, that phrase could be excised so each section's topic would be faster to spot, and there would be fewer unnecessary words. In fact, the section titles don't necessarily have to be posed as questions. For instance, "Using Sessions" would be just as clear as "How do I use sessions?" and faster to read.
It should be noted that this book is best suited for intermediate to advanced PHP programmers, who will certainly get the most out of it. A programmer new to PHP, who would like to begin learning the language, should start with any one of the many tutorial-style PHP books available.
For readers who prefer the portability or environmental benefits of e-books, a PDF version of The PHP Anthology is available from the publisher, on the aforesaid Web page. Any programmer who is — or anticipates — doing PHP work away from their print technical library, should definitely consider obtaining the e-book, which thus can be added to their laptop's development environment, and be readily available for quick reference. The e-book contains all of the content of the print version. It also makes good use of color, for screenshots and other illustrations, as well as using a blue background for the sample code, which is a bit easier to read than the gray used in the print version.
Overall, this new edition of The PHP Anthology offers practical solutions to many common PHP problems, clear explanations of those solutions, and working code — in print and online — that can be quickly used as is or modified as needed. PHP developers should find this book an informative and valuable part of their technical library.

Professional Plone Development
Michael J. Ross writes "Among the hundreds of content management systems (CMSs) available for building Web sites, Plone may not be the most popular; but for the majority of experienced Python developers, it is without equal. This is partly due to Plone being one of the few major CMSs written in Python, and partly due to its powerful extensibility. Customizing and extending Plone, however, are not for the faint of heart. Fortunately, help is at hand, in Professional Plone Development, a book written by seasoned Plone developer Martin Aspeli." Read below for the rest Of Michael's review. Professional Plone Development author Martin Aspeli pages 420 publisher Packt Publishing rating 7/10 reviewer Michael J. Ross ISBN 1847191983 summary A practical exploration of how to extend the CMS Plone. Professional Plone Development was put out by Packt Publishing, on 26 September 2007, under the ISBNs 1847191983 and 978-1847191984. On the book's Web page, visitors can order a copy of the book (more on this later), download the sample source code found in the book, submit feedback, ask questions of the publisher, and download a sample chapter — specifically, Chapter 2, which presents the case study used by the author. For anyone who wants to get the most out of this book, downloading and working through the sample code would be extremely valuable.
The book's material is organized into 19 chapters, spanning 420 pages — despite what is reported on the publisher's Web page, which as of this writing indicates that the book comprises 300 pages. The book's chapters are grouped into four parts. The first one, the briefest, sets the stage for what follows, by presenting a context for Plone development, including the CMS's history, its competition, its use as a stand-alone application versus use as a framework, and other foundational matters. It also introduces the case study — a cinema chain's Web site — used throughout the book to illustrate the concepts being taught. Lastly, the first part of the book covers the development environment needed by the reader to follow along, including discussion of Zope, which is an open source application server designed for creating CMSs and other Web-based applications.
The second part of the book covers Plone customization: basic concepts, laying out a site's strategy, security and workflow issues, add-on products, and creating a new theme. The book's third part, the longest, covers how to extend Plone with new functionality: Zope programming essentials, custom content types, standalone views and forms, working with a relational databases, user management, creating user interfaces with KSS, and more. The fourth and last part of the book addresses real world deployment of one's extensions, including Zope server management, production server setup, LDAP authentication, and possibilities for the future. Unlike most technical books, the author provides at the end a brief yet worthwhile section on where the reader can go next to learn more along the same lines as the book. The brevity of the section is certainly not from a lack of knowledge or helpfulness on the part of the author, but rather the dearth of information available to developers interested in learning about how to extend Plone.
There's a great deal to like about this book. The author clearly possesses the expertise and experience needed for providing instruction on a challenging topic such as this. His explanations are not abbreviated, as seen in so many other technical monographs. Furthermore, most programmers learn best by viewing and mentally dissecting sample code. For such people, Martin Aspeli's practical approach — focusing on a substantial sample application — will prove more engaging and instructive than the made-up and oftentimes overly simplistic examples found in many computer programming books — including the increasingly popular cookbook titles. On the other hand, by placing almost all of the discussion within the framework of a single sample application, the author diminishes the potential of the book for reference purposes. To benefit the most from this book, the reader definitely would want to work through all of the chapters, in detail, and in the order presented.
In presenting the many steps of creating the case study application, the author provides a generous amount of information on what he considers to be best practices, to make the Plone development process more reliable, and the resulting code easier to maintain and further extend in the future. The confident authority with which the author covers these principles, and the validity of the examples provided, demonstrates his knowledge of the subject matter, and reassures the reader that the author has the experience to provide reliable technical guidance.
In terms of prerequisites, readers should have a solid familiarity with Python and Plone. The book covers Plone version 3.0, but still would be of value to developers who have not yet upgraded from an earlier 2.x release.
Professional Plone Development is definitely best suited for Plone developers and administrators from the intermediate to advanced levels. However, even someone fairly new to Plone, would benefit from what it offers. In fact, carefully working through all of the material, and taking the time to really understand it, could take a developer from the beginner to the intermediate level. With further experience, subsequent rereadings of the book would likely yield further insights. It's that kind of book — meaty and in-depth, and not in any way a shallow "dummies" book.
However, there are some criticisms that should be leveled against this book, although none of them have anything to do with the writing of the author or the sample code. Rather, these are recommendations for future improvement directed to the publisher. First and foremost, the book's print on the page, is quite shiny — and not in the sense of a "Firefly" compliment. Rather, it reflects light as if the ink were extremely glossy. As a result, depending upon the placement of one's reading light, the page being viewed invariably has a large shiny spot, forcing the reader to keep rocking the book back and forth, relative to the light source, in order to shift the glare away from the section on the page that is currently being viewed. Of the hundreds if not thousands of technical books I have read, this is the only one with this type of printing, and I hope it is the last. This problem is not seen with the largest text of all, such as "Part N" at the beginning of each of the book's four major parts.
The images in the book, of which there are few, have a high degree of pixelation, which makes them look cheap, though it certainly does not make them impossible to read. As with the book's text, the pictures suffer from the same annoying shininess.
Earlier it was mentioned that the prospective reader can order a copy of the book from the publisher's Web site. However, I would not recommend this until the publisher improves the way that they package their books for shipping. Rather than enclosing the book in a plastic bag or a piece of clean wrapping paper, to protect it, the book is placed bare inside of the shipping box, in which it bounces around during transit, as it makes its way to the purchaser from the shipping/distribution facility. Consequently, the corners and edges of the book are easily curled, and the outside surfaces of the book's cover are scratched from the imperfections found in the shipping box's interior. This shows what can happen with books that are mailed with no internal protection. Publishers should not assume that what the shipping department sees when they place the book in the box, is what the customer sees days later when they receive it. Fortunately, this book is available from all major online booksellers, including the 11 firms listed on the publisher's Web page, for various countries. While this might not guarantee better protection of the book's cover, I have had far fewer similar problems with Amazon.com, for instance.
Despite these production flaws — all of which can be corrected — Professional Plone Development is a worthy addition to the library of any Plone administrator interested in making the most of their Plone installation, any Python developer who wants to create Web sites without reinventing the wheel, and any professional programmer interested in taking advantage of the growing demand for Plone developers.

High Performance Web Sites
Michael J. Ross writes "Every Internet user's impressions of a Web site is greatly affected by how quickly that site's pages are presented to the user, relative to their expectations — regardless of whether they have a broadband or narrowband connection. Web developers often assume that most page-loading performance problems originate on the back-end, and thus the developers have little control over performance on the front-end, i.e., directly in the visitor's browser. But Steve Souders, head of site performance at Yahoo, argues otherwise in his book, High Performance Web Sites: Essential Knowledge for Frontend Engineers." Read on for the rest of Michael's review. High Performance Web Sites author Steve Souders pages 168 publisher O'Reilly Media rating 9/10 reviewer Michael J. Ross ISBN 0596529309 summary 14 rules for faster Web pages The typical Web developer — particularly one well-versed in database programming — might believe that the bulk of a Web page's response time is consumed in delivering the HTML document from the Web server, and in performing other back-end tasks, such as querying a database for the values presented in the page. But the author quantitatively demonstrates that — at least for what are arguably the top 10 sites — less than 20 percent of the total response time is consumed by downloading the HTML document. Consequently, more than 80 percent of the response time is spent on front-end processing — specifically, downloading all of the components other than the HTML document itself. In turn, cutting that front-end load in half would improve the total response time by more than 40 percent. At first glance, this may seem insignificant, given how few seconds or even deciseconds it takes for the typical Web page to appear using broadband. But any delays, even a fraction of a second, accumulate in reducing the satisfaction of the user. Likewise, improved site performance not only benefits the site visitor, in terms of faster page loading, but also the site owner, with reduced bandwidth costs and happier site visitors.
Creators and maintainers of Web sites of all sizes should thus take a strong interest in the advice provided by "Chief Performance Yahoo!," in the 14 rules for improving Web site performance that he has learned in the trenches. High Performance Web Sites was published on 11 September 2007, by O'Reilly Media, under the ISBNs 0596529309 and 978-0596529307. As with all of their other titles, the publisher provides a page for the book, where visitors can purchase or register a copy of the book, or read online versions of its table of contents, index, and a sample chapter, "Rule 4: Gzip Components" (Chapter 4), as a PDF file. In addition, visitors can read or contribute reviews of the book, as well as errata — of which there are none, as of this writing. O'Reilly's site also hosts a video titled "High Performance Web Sites: 14 Rules for Faster Pages," in which the author talks about his site performance best practices.
The bulk of the book's information is contained in 14 chapters, with each one corresponding to one of the performance rules. Preceding this material are two chapters on the importance of front-end performance, and an overview of HTTP. Together these form a well-chosen springboard for launching into the performance rules. In an additional and last chapter, "Deconstructing 10 Top Sites," the author analyzes the performance of 10 major Web sites, including his own, Yahoo, to provide real-world examples of how the implementation of his performance rules could make a dramatic difference in the response times of those sites. These test results and his analysis are preceded by a discussion of page weight, response times, YSlow grading, and details on how he performed the testing. Naturally, if and when a reader peruses those sites, checking their performance at the time, the owners of those sites may have fixed most if not all of the performance problems pointed out by Steve Souders. If they have not, then they have no excuse, if only because of the publication of this book.
Each chapter begins with a brief introduction to whatever particular performance problem is addressed by that chapter's rule. Subsequent sections provide more technical detail, including the extent of the problem found on the previously mentioned 10 top Web sites. The author then explains how the rule in question solves the problem, with test results to back up the claims. For some of the rules, alternative solutions are presented, as well as the pros and cons of implementing his suggestions. For instance, in his coverage of JavaScript minification, he examines the potential downsides to this practice, including increased code maintenance costs. Every chapter ends with a restatement of the rule.
The book is a quick read compared to most technical books, and not just due to its relatively small size (168 pages), but also the writing style. Admittedly, this may be partly the result of O'Reilly's in-house and perhaps outsource editors — oftentimes the unsung heroes of publishing enterprises. This book is also valuable in that it offers the candid perspective of a Web performance expert, who never loses sight of the importance of the end-user experience. (My favorite phrase in the book, on page 38, is: "...the HTML page is the progress indicator.")
The ease of implementing the rules varies greatly. Most developers would have no difficulty putting into practice the admonition to make CSS and JavaScript files external, but would likely find it far more challenging, for instance, to use a content delivery network, if their budget puts it out of reach. In fact, differences in difficulty levels will be most apparent to the reader when he or she finishes Chapter 1 (on making fewer HTTP requests, which is straightforward) and begins reading Chapter 2 (content delivery networks).
In the book's final chapter, Steve Souders critiques the top 10 sites used as examples throughout the book, evaluating them for performance and specifically how they could improve that through the implementation of his 14 rules. In critiquing the Web site of his employer, he apparently pulls no punches — though few are needed, because the site ranks high in performance versus the others, as does Google. Such objectivity is appreciated.
For Web developers who would like to test the performance of the Web sites for which they are responsible, the author mentions in his final chapter the five primary tools that he used for evaluating the top 10 Web sites for the book, and, presumably, used for the work that he and his team do at Yahoo. These include YSlow, a tool that he created himself. Also, in Chapter 5, he briefly mentions another of his tools, sleep.cgi, a freely available Perl script that tests how delayed components affect Web pages.
As with any book, this one is not perfect — nor is any work. In Chapter 1, the author could make more clear the distinction between function and file modularization, as otherwise his discussion could confuse inexperienced programmers. In Chapter 10, the author explores the gains to be made from minifying JavaScript code, but fails to do the same for HTML files, or even explain the absence of this coverage — though he does briefly discuss minifying CSS. Lastly, the redundant restatement of the rules at the end of every chapter, can be eliminated — if only in keeping with the spirit of improving performance and efficiency by reducing reader workload.
Yet these weaknesses are inconsequential and easily fixable. The author's core ideas are clearly explained; the performance improvements are demonstrated; the book's production is excellent. High Performance Web Sites is highly recommended to all Web developers seriously interested in improving their site visitors' experiences.

High Performance Web Sites
Michael J. Ross writes "Every Internet user's impressions of a Web site is greatly affected by how quickly that site's pages are presented to the user, relative to their expectations — regardless of whether they have a broadband or narrowband connection. Web developers often assume that most page-loading performance problems originate on the back-end, and thus the developers have little control over performance on the front-end, i.e., directly in the visitor's browser. But Steve Souders, head of site performance at Yahoo, argues otherwise in his book, High Performance Web Sites: Essential Knowledge for Frontend Engineers." Read on for the rest of Michael's review.

The History of the Federal Reserve
Michael J. Ross writes "Money plays a key role in modern life; in fact, for some people, nothing is more important than acquiring more of it. Yet most people do not know what money really is, how it is created, how its supply is expanded and contracted, and who benefits from those changes. In the United States, the central figure in this ongoing drama, is our central bank, the Federal Reserve, whose history, power, and effects are explored in G. Edward Griffin's fascinating book The Creature from Jekyll Island: A Second Look at the Federal Reserve." Read on for the rest of Michael's review. The Creature from Jekyll Island author G. Edward Griffin pages 624 publisher American Media rating 9 reviewer Michael J. Ross ISBN 0912986212 summary A compelling history and indictment of the Federal Reserve system For the citizens of the United States and several Latin American countries, the "coin of the realm" is the US dollar, which is, in simple terms, created by the Federal Reserve, a.k.a., the Fed. But who created the Federal Reserve, and why? The subjects of banking in general, and the Federal Reserve in particular, would be considered by most Americans to be dry, boring, and of little importance to their day-to-day life. But those same people are endlessly fascinated by how to make more money (with minimal effort, such as the lottery), how to spend as little of it as possible (coupons never go out of style), and how to maximize one's investment returns. Why this disconnect? Why do Americans care so little about the origins of that which they spend a third of their time pursuing, and seemingly another third spending?
Some of these "salary slaves" may understand that their money serves as a store of wealth and a medium of commercial exchange, which makes possible their daily financial transactions without the need for bartering. But, for the most part, they do not understand the critical importance of what is backing that money, if anything; how that money comes into existence, and what debt offsets it; what entities control the supply and distribution of that money; and how those changes can be used to legally steal purchasing power from victims who may not be entirely unsuspecting, but do not truly comprehend how they are getting ripped off.
The typical American, if he or she has given any thought to the matter, would consider the following statements to be true: The Federal Reserve is federal, i.e., a part of the US government. The Federal Reserve is a reserve, i.e., it has monetary savings of real value. The Federal Reserve serves the public, and is not a cartel of private banks serving itself. The US dollar has real value, i.e., it represents tangible wealth, such as gold securely stored at Fort Knox. Inflation is an increase in prices. Inflation is caused by greedy companies, not the US government or the Federal Reserve.
As G. Edward Griffin makes clear in his book, none of these beliefs are true — regardless of how well entrenched they are in our conventional "wisdom." He also explains why the US government and the Federal Reserve have their own reasons for being in no hurry to eliminate this ignorance. Yet these topics are just a small portion of what is covered in his far-ranging discussion of the theory and history of money and banking, particularly within the United States.
Spanning 624 pages, the material is organized into 26 chapters, which are grouped into six sections: "What Creature Is This?" (the Federal Reserve's shameful birth, and the shenanigans of the Fed, S&Ls, the IMF, and the World Bank), "A Crash Course on Money" (money, gold, debasement, fiat money, fractional-reserve banking, and money creation), "The New Alchemy" (the Rothschilds, J.P. Morgan, and banker financing of wars and revolutions), "A Tale of Three Banks" (America's failed experiments with central banking, and the American Civil War), "The Harvest" (the unconstitutional creation of the Federal Reserve, and its dreadful effects, including the Crash of 1929), "Time Travel into the Future" (current crises caused by central banking, how they can be reversed, future scenarios, and what the individual can do regardless). Every one of the six sections begins with a brief summary, as does every chapter, with every chapter wrapped up with a more extensive summary.
The section summaries also appear in the table of contents, which precedes a preface and the author's acknowledgments. These are followed by a delightful introduction — a piece from the British humor magazine Punch, comprising a rather telling exchange between an unusually honest banker and a soon-to-be-disillusioned bank customer. The book contains three appendices: a summary of the structure and function of the Federal Reserve system; natural laws of human behavior in economics; and whether the M-1 measure of money is subtractive or accumulative. The author also provides an index, as well as an impressive bibliography, reflecting his extensive research on the topics. In addition, the author invites readers to join Freedom Force, an organization dedicated to increasing liberty in the United States, curbing federal totalitarianism, and abolishing the Federal Reserve — all through peaceful participation in government, and the shaping of public policy starting at the grassroots level.
The Creature from Jekyll Island is published by American Media, under the ISBNs 0912986212 and 978-0912986210. It first came out in July 1994, and is now in its fourth edition, and its 19th printing. It also has Japanese and German editions, published in February 2005 and August 2006, respectively. On the book's Web page, visitors will find testimonials and comments from readers, updates to the book, a review of the book by Jane H. Ingraham of The New American, and G. Edward Griffin's response to a critique of his book by Edward Flaherty, who holds a Ph.D. in Economics. On that Web page, interested readers can order audio cassettes or CDs of the author's lecture, based upon this book, and produced in 1998.
My only criticisms of the book concern not the material itself, but its production — more specifically, the printing and layout, presumably chosen and thus fixable in the future by the publisher. The generous font size used throughout the volume, makes it easy to read; but the bold text, such as the subheads found in every chapter, is a bit rough-edged — on some pages worse than others. The subheads, already bolded, do not need to be in all uppercase; the publisher should choose one or the other. In addition, the inside margin length is a bit too small, forcing the reader to crack open the book more than should be needed, in order to comfortably read the text closest to the binding. In future editions, some of the space in the outer margin could be used to solve the problem, without any change to the words on each page, and thus the length of the book.
But aside from these minor flaws, this book is to be highly recommended. The Creature from Jekyll Island is a remarkably thorough, detailed, and challenging critique of central banking and America's latest incarnation of it, the Federal Reserve. G. Edward Griffin's precision of language, and his interweaving of the major players and their motives, makes for a most compelling historical study.

GWT in Action
Michael J. Ross writes "Server-side computer languages, such as Java, possess numerous advantages over their client-side counterparts — including more robust integrated development environments (IDEs). In contrast, Web-focused languages, such as JavaScript, benefit from the global accessibility of the Internet. Bridging this gap, and leveraging the strengths of both sides, has long been an objective of the software development community — though not all attempts have been successful, e.g., Java applets. The Google Web Toolkit (GWT) is the latest attempt, and shows considerable promise, as illustrated in a new book intended to help programmers learn this new technology: GWT in Action." Read on for the rest of Michael's review GWT in Action author Robert Hanson and Adam Tacy pages 600 publisher Manning Publications rating 6 reviewer Michael J. Ross ISBN 1933988231 summary A practical introduction to programming with the Google Web Toolkit (GWT). Written by Robert Hanson and Adam Tacy, this book was published by Manning Publications on 5 June 2007, under the ISBNs 1933988231 and 978-1933988238. For any prospective reader who would like to learn more about the book, they can first try the book's Web page, where they will find online versions of the "about this book" section, table of contents, preface, and index. The publisher offers two freely downloadable chapters, "Creating the Default Application" and "Communicating with GWT-RPC," in PDF format. In addition, there is a link to purchase the book's electronic version, and a link to the author's forum, where readers can post questions about the book or GWT, and likely receive a response — perhaps even by one of the authors.
The book's 17 chapters are organized into four parts, and cover a generous number of topics: introduction to GWT; creating the default GWT application; building your own application based upon the default one; creating widgets and panels, including composite panels; processing user events; creating JSNI components; modularizing your code; communicating using GWT-RPC; client-side RPC; classic Ajax and HTML forms; using JSON for interoperability; automatically generating code; GWT's native properties; testing and deploying GWT applications; more on the inner workings of GWT itself. The book has no appendices, but a substantial index, which is essential for such a technically detailed subject area.
GWT in Action is clearly intended to be a practical and fairly comprehensive coverage of Google's new toolkit. Almost all of the GWT concepts are explained within the context of developing a substantial sample application, the Dashboard, created by the authors. The reader is encouraged to follow along as the authors build the application, thereby learning from doing — almost always an effective approach. At 600 pages, with almost none of the formatting padding found in far too many technical books nowadays, the authors have not skimped on providing the reader with a lot of information. Furthermore, their treatment of application deployment is far better than any other I have encountered.
Unfortunately, the book has many weaknesses. On an overall basis, the order of presentation is at times disjointed — seemingly dictated more by the Dashboard and less by the most logical order for someone new to GWT. Compounding the problem, the authors frequently refer to advanced topics, covered in greater detail later, and also repeat earlier information, occasionally several times. Despite promises to provide a gentle exposition, it can be difficult at times for the reader to determine if any critical steps were skipped, as a consequence of key instructions for building the sample application being spread out, and interspersed with too many references to general comments covered earlier. In turn, readers will likely find it frustrating to try to get the sample application working at each step of the development process — and not just at the end, with the complete code.
One source of these difficulties, is that in the first few chapters, the authors try to introduce too many topics all at once, and as a result do not thoroughly discuss each one in its own section. Instead, they break up the information over multiple sections, scattered throughout the book. An example of this is internationalization. Section 2.2.4 is titled "Implementing Internationalization," and yet provides almost no details, and is essentially unusable by itself. At the very least, it should mention that later sections 3.2.1 and 15.3 provide a lot more information. Furthermore, internationalization was introduced far too early in the book, and greatly complicates the process. Instead, the authors should have created a simple application using only English for the user interface, and introduce internationalization later, after fully explaining the basics of turning Java code into JavaScript functionality.
Part I of the book is the weakest of all of them, which may, sadly, turn off readers who would otherwise get to the better material later. The authors are clearly enthusiastic about the topics at hand, and the number of moving parts associated with Java/JavaScript/GWT development is certainly not trivial. Nonetheless, those initial chapters would greatly benefit from a rewrite; this would make the material more comprehensible and easier to follow, step-by-step.
We can mention some specific flaws: A book like this that is introducing a new technology, must take care to not leave the unwarned reader wondering if they have been left behind in the steps. People reading some of the earlier material may conclude that those steps have already been assumed by the authors, and will not be covered. The authors do not mention how to obtain and install GWT until page 30; that should be right up front. The authors do not appear to mention which version of GWT they used for the book. (I chose 1.3, not 1.4RC, available as of this writing). Any reader trying to follow along and implement their example application (the Dashboard) will probably find several hurdles. First of all, make sure that you have version 1.4 of GWT installed, and not 1.3.3, which does not include some of the panels and widgets used in their sample code.
In Chapter 1, they modify a "Hello world" application to create another application that shows a tic-tac-toe board that has clickable squares, but does not play the game. Chapter 2 describes this as "a fully functioning Tic-Tac-Toe application," which is like claiming a program works because it compiles. Also in Chapter 2, their discussion of development alternatives is slowed down by repetition of the same information. The sample code in the book has minor inconsistencies. For example, naming a password String "oldPass" in one method, then "old" in another, related method. There are other instances, but these give one an idea of some of the inconsistencies.
The coverage of topics is generally quite thorough, though at times verbose and redundant — particularly in Chapter 2, though it is certainly not limited to that chapter. The second and third paragraphs in Chapter 3, for instance, continue the repetitious style which is found in many places throughout the book, and likely has made it longer than necessary. In Chapter 4, the first two pages explain what widgets are, several times, and conclude with a picture of a button — as if any reader who has made it that far into the book doesn't know what a button is. The book could certainly use some trimming.
The downloadable source code is not complete. For starters, it is missing the code from Chapters 1 and 2, though admittedly none of that is too long. The code provided for Chapter 4 is just a portion of what is displayed in the book. Moreover, the directory paths in the sample code archive files, are not consistently named, and some may even be incorrect. For example, the code for Chapter 5 has a folder named "Dashboard — Chapter 4." That sort of thing does not instill confidence in the typical reader. The authors should revisit the sample code — making it complete and consistently named.
The publisher's page for the book does not appear to have a link for errata; perhaps none have been reported yet. Here are some: On page 75, in Table 3.1, in the left-hand column, "gwt-onLoadErrorFn" should instead read ""gwt:onLoadErrorFn." On page 77, in the second paragraph, the file name extension should be all lowercase, not all uppercase. On page 78, in Listing 3.6, the String parameter in the first label.setText() call should be delimited with straight quotes, not curly quotes. (Microsoft Word strikes again?!) On page 81, in the third paragraph, "comply to" should read "comply with." On pages 87 and 88, the -whitelist and -blacklist option values each contain an extraneous space before the "^." There are undoubtedly more such errata throughout the book, and can be corrected in the next edition; but these are enough to at least get an errata file started. Fortunately, none of them would lead an alert reader astray.
Even though the book could use significant reorganization and streamlining in the next edition, GWT in Action is packed with practical information on a wide range of GWT topics.

GWT in Action
Michael J. Ross writes "Server-side computer languages, such as Java, possess numerous advantages over their client-side counterparts — including more robust integrated development environments (IDEs). In contrast, Web-focused languages, such as JavaScript, benefit from the global accessibility of the Internet. Bridging this gap, and leveraging the strengths of both sides, has long been an objective of the software development community — though not all attempts have been successful, e.g., Java applets. The Google Web Toolkit (GWT) is the latest attempt, and shows considerable promise, as illustrated in a new book intended to help programmers learn this new technology: GWT in Action." Read on for the rest of Michael's review GWT in Action author Robert Hanson and Adam Tacy pages 600 publisher Manning Publications rating 6 reviewer Michael J. Ross ISBN 1933988231 summary A practical introduction to programming with the Google Web Toolkit (GWT). Written by Robert Hanson and Adam Tacy, this book was published by Manning Publications on 5 June 2007, under the ISBNs 1933988231 and 978-1933988238. For any prospective reader who would like to learn more about the book, they can first try the book's Web page, where they will find online versions of the "about this book" section, table of contents, preface, and index. The publisher offers two freely downloadable chapters, "Creating the Default Application" and "Communicating with GWT-RPC," in PDF format. In addition, there is a link to purchase the book's electronic version, and a link to the author's forum, where readers can post questions about the book or GWT, and likely receive a response — perhaps even by one of the authors.
The book's 17 chapters are organized into four parts, and cover a generous number of topics: introduction to GWT; creating the default GWT application; building your own application based upon the default one; creating widgets and panels, including composite panels; processing user events; creating JSNI components; modularizing your code; communicating using GWT-RPC; client-side RPC; classic Ajax and HTML forms; using JSON for interoperability; automatically generating code; GWT's native properties; testing and deploying GWT applications; more on the inner workings of GWT itself. The book has no appendices, but a substantial index, which is essential for such a technically detailed subject area.
GWT in Action is clearly intended to be a practical and fairly comprehensive coverage of Google's new toolkit. Almost all of the GWT concepts are explained within the context of developing a substantial sample application, the Dashboard, created by the authors. The reader is encouraged to follow along as the authors build the application, thereby learning from doing — almost always an effective approach. At 600 pages, with almost none of the formatting padding found in far too many technical books nowadays, the authors have not skimped on providing the reader with a lot of information. Furthermore, their treatment of application deployment is far better than any other I have encountered.
Unfortunately, the book has many weaknesses. On an overall basis, the order of presentation is at times disjointed — seemingly dictated more by the Dashboard and less by the most logical order for someone new to GWT. Compounding the problem, the authors frequently refer to advanced topics, covered in greater detail later, and also repeat earlier information, occasionally several times. Despite promises to provide a gentle exposition, it can be difficult at times for the reader to determine if any critical steps were skipped, as a consequence of key instructions for building the sample application being spread out, and interspersed with too many references to general comments covered earlier. In turn, readers will likely find it frustrating to try to get the sample application working at each step of the development process — and not just at the end, with the complete code.
One source of these difficulties, is that in the first few chapters, the authors try to introduce too many topics all at once, and as a result do not thoroughly discuss each one in its own section. Instead, they break up the information over multiple sections, scattered throughout the book. An example of this is internationalization. Section 2.2.4 is titled "Implementing Internationalization," and yet provides almost no details, and is essentially unusable by itself. At the very least, it should mention that later sections 3.2.1 and 15.3 provide a lot more information. Furthermore, internationalization was introduced far too early in the book, and greatly complicates the process. Instead, the authors should have created a simple application using only English for the user interface, and introduce internationalization later, after fully explaining the basics of turning Java code into JavaScript functionality.
Part I of the book is the weakest of all of them, which may, sadly, turn off readers who would otherwise get to the better material later. The authors are clearly enthusiastic about the topics at hand, and the number of moving parts associated with Java/JavaScript/GWT development is certainly not trivial. Nonetheless, those initial chapters would greatly benefit from a rewrite; this would make the material more comprehensible and easier to follow, step-by-step.
We can mention some specific flaws: A book like this that is introducing a new technology, must take care to not leave the unwarned reader wondering if they have been left behind in the steps. People reading some of the earlier material may conclude that those steps have already been assumed by the authors, and will not be covered. The authors do not mention how to obtain and install GWT until page 30; that should be right up front. The authors do not appear to mention which version of GWT they used for the book.

Learning Joomla! Extension Development
Michael J. Ross writes "One of the most powerful and popular content management systems (CMSs) is Joomla, a superior derivative of Mambo. Out of the box, Joomla makes it relatively easy to build Web sites that allow collaborative editing of content, attractive styling via prebuilt templates, and many more features. A Joomla-based site can be further improved by adding custom modules, components, and other extensions to the CMS, without any modification to the core Joomla code. A resource that explains how to do this, is Learning Joomla! 1.5 Extension Development: Creating Modules, Components, and Plugins with PHP, by Joseph L. LeBlanc." Read on for the rest of Michael's review. Learning Joomla! 1.5 Extension Development author Joseph L. LeBlanc pages 176 publisher Packt Publishing rating 8 reviewer Michael J. Ross ISBN 1847191304 summary A practical tutorial for creating Joomla! 1.5 extensions
The book is put out by Packt Publishing, under the ISBNs 1847191304 and 978-1-847191-30-4. The publisher maintains a page on their site dedicated to the book, where visitors can read summaries of the chapters and the overall book, order the e-book version (in PDF format) at a discount, download the book's sample source code, read and submit errata and feedback, and download a sample chapter, namely, "Chapter 1: Joomla! Extension Development: An Overview" (also in PDF format). Note that, as of this writing, the errata and feedback do not have their own links, but are located on the page accessible via the link "Code download," which should be clarified.
The book's title page bills it as "A practical tutorial for creating your first Joomla! 1.5 extensions with PHP," and that is exactly what the book is. Rather than organizing the information in a cookbook style — which is quite popular in programming books nowadays — this particular one uses a narrative approach, in which the author illustrates the concepts by stepping the reader through an example project. He begins with a clean install of Joomla, without any of the sample data, and shows how to "build extensions to create, find, promote, and cross-link restaurant reviews."
The nine chapters of the book are organized in a logical manner, and in the order that the typical developer would go about extending a Joomla-based site: overview; Joomla's component structure and registration; backend and front-end development; module development; using the model-view-controller design pattern (MVC); creating plug-ins; adding configurability for the extensions that you have created; packaging the extension elements for use by other Joomla developers.
In explaining the key concepts and procedures for building custom extensions to a Joomla site, the author takes a methodical approach, with a healthy balance between exposition, sample code, and illustrative figures. The chapters read quickly, and the code changes from one section to the next are helpfully bolded. The chapter summaries, as with most programming books, add no value, and could be beneficially dropped, thereby saving space.
The author states in the first chapter that there are three types of extensions within Joomla: components, modules, and plug-ins. This could be confusing to anyone who has read the articles that help introduce Joomla to the new developer, and are contained in the sample data found in Joomla version 1.5. Those articles include one titled "Extensions," which lists two additional extension types — templates and languages — not considered such by LeBlanc. However, that article does not make clear as to why templates and languages should even be considered extensions, which seems counterintuitive at first glance.
The presentation of all of the material in LeBlanc's book is not perfect, but it is certainly more than adequate. It is unfortunate that the book does not have a lay-flat binding, which tends to be more of a problem with slender volumes such as this one (176 pages), since much thicker books have more weight to keep both sides down on the table at the same time when the book is open. All of the screenshots have a bit too much pixelation, which makes the smallest text within the screenshots more difficult to read. However, none of that text is unreadable. The book's text outside of the screenshots is quite easy to read, with a generously-sized font and a logical layout of each page's material. Almost every page has two horizontal lines, one at the top, and one at the bottom; they serve no purpose, and could be eliminated to save ink and space, as could the brackets around every page number. The same is true for the much larger and thicker brackets used to delineate warnings, notes, tips, and tricks. There were a few other very minor flaws in the book. For instance, in the information about the reviewer, "MySQL" is misspelled. In the Table of Contents, the "Available Toolbar Buttons" line appears to be one font size too small, and thus inconsistent with the other subsection heads. All of these weaknesses are of little consequence and could be fixed in the next edition.
Even if a reader initially had no interest in developing their own extensions to Joomla, this book could easily spark their interest, given that the book shows just how powerful those extensions can be, as well as how doable they are, by any competent programmer familiar with PHP and MySQL. In fact, even if the reader were to later decide that they had no interest in creating any extensions, they could still benefit from the book's discussion of how components are structured within Joomla — a more clear explanation than anything I have seen in the official Joomla documentation. Joomla may be an excellent CMS, but the documentation quality does not come close to the value of Joomla itself. That is why there is such a great need for books such as this one.
Although Learning Joomla! 1.5 Extension Development: Creating Modules, Components, and Plugins with PHP has some weaknesses — as do most if not all technical books nowadays — for any developer interested in getting the most out of Joomla by building custom extensions, LeBlanc's contribution should prove especially informative and useful.

The Mechanized Future
Michael J. Ross and Dan Sisson write "In our increasingly mechanized world, we repeatedly hear promises that every new digital product, computerized service, or other form of technology, will make our lives easier — bestowing greater leisure, health, and happiness. Yet are any of those promises being fulfilled? Are we not instead becoming slaves to the very "conveniences" that we struggle to master? These weighty questions are addressed by Steve Talbott in his book Devices of the Soul: Battling for Our Selves in an Age of Machines." Read below for the rest of Michael and Dan's review. Devices of the Soul author Steve Talbott pages 281 publisher O'Reilly Media rating 7 reviewer Michael J. Ross and Dan Sisson ISBN 0596526806 summary A passionate warning against technology overtaking our lives Published by O'Reilly Media in April 2007, under ISBNs 0596526806 and 978-0596526801, Devices of the Soul argues that we are now blindly accepting technology with little or no countervailing efforts or even awareness, and we are paying a terrible toll, both individually and as a society.
From the day a child of the 21st century begins his education, he is confronted with mind-numbing statistics, numbers, and facts via the computer — which he must accept. Perhaps even more important, he must master its "techniques" as the sine qua non tool to be successful in life. This is not a voyage of self-discovery; it is a demand by "the system" that the individual accept a way of viewing the world that invades, conquers, and ultimately controls his life. The child will learn most of what he knows with it, play with it, talk with it, and allow his thinking to be ruled by it — all because it is the magical machine that gives him access to the world's knowledge, e.g., the Internet.
By the time this child makes the transition from high school to college, he will be required to accept a curriculum that too often lacks meaning and content, that fails to allow him to satisfy his own curiosity about the challenges facing humanity, and is, moreover, expensive and will likely lead to indebtedness. There are few alternatives to this gauntlet, especially if one wishes to belong to the 'credentialed society', which determines modern man's measure of success.
Education is only the first stage in the numbing of our consciousness. What follows is built upon this edifice. Our acceptance of machines — ubiquitous in our everyday lives — provides our food, transportation, entertainment, information, and prestige — in sum, everything we need to function in modern society.
Talbott shows how the machines we use create a grand illusion, namely, that by having every technological gadget, we will save time and money, and be able to spend more time with our family and loved ones. However, that leisure time never materializes. The technology costs more, not less. Consequently, we find ourselves in a perpetual struggle to preserve a bare minimum of human emotions and instincts.
The next stage in the individual's life is integration into the mature world of the computerized economy, i.e., when he becomes a "stakeholder." He accepts a world that does away with human values and subordinates him to "market values." Furthermore, he is bound to lose his sense of privacy.
It follows that almost everyone willingly accepts that advancement in life and career increasingly requires having electronic conversations with machines — and eventually robots — that will never ask us what our personal assumptions and/or values are, and have no intentions of doing so. In short, our resistance to the machine fades. It is "far easier to assign the intelligence solely to the machine than to seek out those tortured pathways" to the human urges within us. Society itself, not just the individual, says Talbott, "is unsurprisingly assuming the character of our technology."
The outcome is grim: "Historically, there appears to be an element of tragedy in all this. We stumble along in ignorance and, by the time we realize the subtle ways our actions have caught up with us, the damage and loss are already irrevocable."
Technology expresses itself in numbers and computations divorced from human values. Efficiency is nearly the sole criterion by which modern corporations make decisions, and it is no accident that these two ideas, human values versus efficiency, are mutually exclusive. In objecting to the mess we humans have created, Talbott notes: "If you want human values, if you want qualitative distinctions, then your theoretical constructs must retain those values and distinctions every step of the way. The minute you allow them to collapse into number alone, you have no way to get back from there to the qualitative world."
Despite these tragic overtones, he argues that we can and must return to that qualitative world where we can realize our deepest human qualities. We can retain our humanity in connection to the natural world, despite using tools skillfully, as exemplified by the wily trickster Odysseus, as well as Tomo, a member of the Waorani Indians in the Amazon jungles of Ecuador who demonstrated phenomenal knowledge of his world.
His prescription for humanity's emergence from this present Dark Age also includes developing a strong sense of history. We must realize how other humans expressed their individuality, and realized their hopes and dreams. Despite the fact that Americans generally have little appreciation for or cognizance of history, there may come a time when reading history may be the only place to find models of human behavior that went against the technophilic grain.
Interspersed throughout his analysis, Talbott offers suggestions to arrest this headlong rush into a mechanized future. They tend to be general in nature, such as urging us to seek a sense of "place," and to engage in conversations with our fellow men (and even our machines) to remind them of our human needs. Echoing Edward Abbey, who attempted to alert us to the environmental disasters of the 1960's with books like The Monkey Wrench Gang, Talbott writes, "This may at times require us to throw a wrench into the machinery in order to serve the worthy human intentions behind it."
Despite Talbott's skills as a writer, the book, sadly, has some substantial flaws. Two of the most obvious are the overly long digressions into the stories of Jacques Lusseyran and Martha Beck, which admittedly are fascinating, but delay the presentation of more topical material. Furthermore, they suggest that Talbott is misidentifying the emotional power of those stories as proof of his arguments, and thus committing the common error of anecdotal evidence. Even worse, they border on romanticizing blindness and Down syndrome, respectively.
He also fails to address a major factor in our growing discontent with the Information Age: the nonstop ratcheting up of our expectations, driven largely by marketing on the seller side, and a lack of philosophic questioning on the consumer side.
A common pattern in the book is a deep criticism of any given aspect or consequence of technology, to the extent that Talbott appears to be arguing that we should do away with it completely. But he often then wraps up his analysis by briefly contradicting the earlier implication, and stating that he does not believe the phenomenon at issue should be eradicated. This schizophrenic reasoning mixes bold, blanket criticisms with assurances to the contrary. Yet one may argue that, with so much of current social discourse failing to question technology, its critics must never err with overly cautious warnings.
There are other problems in his analysis: He invests much hope in what he terms "conversation," "meaning," and "value" — not clearly specified, and yet spoken of highly. He fears machine intelligence (and perhaps rightly so), and doubts its viability, but fails to understand its potential for emergence. Even though a former computer programmer, he does not seem to understand the value of abstraction, and the possibility that it can be used beneficially, without being considered the only source of important knowledge. Lastly, it is odd that he does not cite the pioneering work of a well-known predecessor, Jacques Ellul, in The Technological Society.
Nonetheless, the issues that Talbott raises are of critical importance — so much so that they make his lapses of logic that much more maddening. Because so much is at stake, our efforts at analyzing, understanding, and solving these problems, must be proportionally energetic and effective. Technophiles may dismiss his entire effort based upon the book's weaknesses, and consequently miss out on the valuable gist of his viewpoint. Similarly, impatient readers in our age of limited attention spans, might not make it through the aforesaid tangents, and likewise miss out.
The issues that he discusses should be raised more often and more loudly, with broader acceptance and expansion of the debate and its importance. Otherwise, we will continue our robotic march deeper into a future that is controlled more by soulless devices, and less by skeptical humans. If we fail completely to change course, we may be saddled with a life that is intolerable to the human spirit.
Devices of the Soul is an insightful, disturbing, imperfect, eloquent, and important contribution to what may ultimately become the most critical debate in the intensifying conflict between humans and our technological creations: Humans may survive, but will our humanity?

Pro Drupal Development
Michael J. Ross writes "If a Web site needs to be developed as quickly as possible, or it needs to support collaborative content, then usually the best approach is to use a content management system (CMS). There are many CMSs from which a Web developer could choose, including Drupal, which is considered by many to be the most powerful, extensible, and logically organized of them all. Installing Drupal and using it to create a simple site, is fairly straightforward, in part due to its relatively excellent documentation. For much of its existence, there has been far less information available on how to extend a Drupal site with one's own modules, themes, blocks, etc. That need is now met by a new book, Pro Drupal Development." Read on for the rest of Michael's review. Pro Drupal Development author John K. VanDyk and Matt Westgate pages 428 publisher Apress rating 9 reviewer Michael J. Ross ISBN 1590597559 summary A detailed guide to customizing a Drupal-based Web site
The book was written by John K. VanDyk and Matt Westgate, both of whom are experienced computer programmers, who years earlier had created their own CMS. In their book's Introduction, they confess to discovering Drupal and its many advantages, switching over to it, and presumably abandoning further development of their own CMS. This speaks volumes about their regard for Drupal, because an individual programmer or programming team can give no greater vote of confidence for a technological product than to voluntarily end primary allegiance to a competing product that they themselves birthed and nurtured.
Pro Drupal Development was published by Apress, on 16 April 2007, under the ISBNs 1590597559 and 978-1590597552. The publisher offers a Web page on their site dedicated to the book, where the visitor will find all of the book's source code, as well as the table of contents and a sample chapter (Chapter 8 — The Theme System), in PDF format. In addition, there is a link for errata, which leads to the authors' own book site. At the time of this writing, there are three dozen entries, contributed by the authors and their readers. The authors' site also has links for downloading the source code by individual chapter, and a blog that focuses on the book.
The book's material, spanning 428 pages, is organized into 23 chapters and two appendices. Unlike the majority of technical books nowadays, this one does not have the chapters organized into labeled parts. Nonetheless, the chapters and appendices roughly fall into three categories: how Drupal works (Chapters 1, 19, and 23, and Appendix A), how to customize it (Chapters 2-18 and 22), and how to optimize your Drupal development efforts (Chapters 20-21, and Appendix B). The customization chapters cover a wide range of topics: modules, menus, databases, users, nodes, themes, blocks, forms, filtering, searching, indexing, files, taxonomy, caching, sessions, jQuery, localization, and optimization.
Each one of these topics is explored in laudable detail, with plenty of sample code and figures to illustrate the key concepts. The greatest strength of this book is the depth of its coverage, and the methodical way that the authors go about presenting the material. They are clearly quite serious about Drupal itself, and about conveying to the reader all of the knowledge that they believe is important for the reader to master. In fact, anyone attempting to read the book cover to cover might find the presentation quite dry, with no evidence of humor or even a sense of fun, unlike so many other recent programming books. On the other hand, one can argue that the value of this information alone to the reader who is equally serious about mastering Drupal, should be sufficient. Regardless, be warned that this is definitely not a book that one can read through at a fast pace, absorbing the bulk of the information. The innards of Drupal alone make it a challenging subject for dissection; learning how to modify Drupal's behavior, is even more so.
Yet if anyone is interested in mastering the inner workings of Drupal, and how to customize them, this is the book of choice. It may be a bit dry, but it is quite meaty, and the material is clearly presented. Moreover, the publisher, Apress, has done an admirable job with this title. The layout is clear; the index is substantial; and, as with their other titles, they offer two different versions of the table of contents — high-level, listing the chapter titles only, and detailed, listing the sections and subsections within those chapters.
Another aspect of this book that I applaud is the efficient use of page space, through the use of top and bottom margins that are noticeably smaller than those found in the typical computer programming book. This is especially true of the bottom margins. For instance, on page 117, the text comes within one centimeter of the bottom edges the page — something I've never seen before in a professionally printed book. At first it might strike one as sloppy, but actually should be appreciated by anyone who is tired of technical books using excessive margins for padding out a much more limited amount of information into an even greater number of pages. This is a practice that I would recommend to all other publishers, technical or otherwise.
However, the book does have some weaknesses, which is probably to be expected in any first edition. The sample source code in many cases could benefit from more use of whitespace — particularly for the PHP code. But with any code found in a book, there is always the possibility that such instances of compressed code result from a conscious decision given the limited width of the printed page. But in most such cases in this book, that reason would not be applicable.
The authors do not warn the reader that a solid understanding of PHP is needed for using the book's ideas and sample code. Near the end of the Introduction, they suggest that if the reader is new to Drupal, then he or she should read the chapters in sequence. The authors should also note that if the reader is new to PHP, then it would be better to first get up to speed on PHP before trying to digest and make use of this book. Such points might be obvious to most readers, but they should be clarified up front, perhaps in the Introduction, for the benefit of anyone browsing this title in a bookstore, and wondering if they already possess the technical know-how required by the book.
Similarly, the authors also do not mention that the book is, for the most part, only applicable to Drupal version 5, and not version 4 or earlier versions, since there have been some dramatic changes with the release of version 5. In fact, given the extent of the changes and how that would impact the utility of the book depending upon what version of Drupal the reader is using, it should be noted on the book's cover, as an increasing number of publishers are doing.
A couple of minor problems were in evidence in the first dozen pages. On page 3, the authors refer to "user 1," which is likely to confuse most readers, because it looks like a username, and would be unfamiliar to someone who has installed Drupal and created a Web site, without extensive reading of the Drupal documentation. On page 11, the authors discuss core modules, and where they can be seen listed in the administration area of Drupal. But the path that they provide, "sites/all/modules," is incorrect, because that is where user-added modules are placed, of which there are none in a default installation. (The second mention of that path, in the fourth paragraph, is correct.)
Lastly, when the book is opened up to any of the pages not near the center, the book immediately flops closed. The use of lay-flat binding is strongly urged, for future editions of this book and all others that Apress offers.
Despite these weaknesses — all of which are fixable — Pro Drupal Development is strongly recommended for any PHP programmer who wants a truly in-depth look at how Drupal works and how to make the most of it.

MySQL Cards and Charts
Michael J. Ross writes "Database programmers using MySQL frequently have a need to verify the name or parameter list of a MySQL function, or to check a statement or the data types available within its implementation of SQL. This typically occurs when the programmer is caught up in a coding session, and would much rather not break their creative flow by searching Web sites for the needed information, or stepping away from their computer to hunt for a reference book. In these cases, nothing could be more valuable than a concise summary of all SQL statements and MySQL functions, in a form compact enough to be kept within reach on the desk or tacked up to the nearest wall space. This is the goal of the VisiBone MySQL Cards and Charts." Read on for the rest of Michael's review. MySQL Cards and Charts author Bob Stein pages 4 publisher VisiBone rating 10 reviewer Michael J. Ross ISBN N/A summary High-quality reference materials for MySQL functions and SQL statements These two products contain the same information, with the same formatting and color coding. They differ primarily in their construction, sizes, and likely destinations. The MySQL Cards — often referred to as cheat sheets — are 8.5 by 11 inches in size, made of card stock that has been laminated on both sides of each pair of cards, for a total of four pages of information. The MySQL Chart is 24 by 33.3 inches, printed of course on only one side. The VisiBone Web page devoted to these products notes that the cards have the advantage of portability, while the chart has the advantage of presenting all of the information in one glance. (The Web site fails to mention that the large chart has the additional advantage that it can be used to cover blemishes on a wall, such as those caused by a Web programmer banging his head against it when wrestling with browser incompatibilities.)
The March 2007 edition of the cards and chart cover MySQL version 5.2 and ISO/ANSI SQL 2003 specification. Such a tremendous amount of technical information needed to be packed into relatively small form factors, offering limited space — especially compared to books. Consequently, all of the available space had to be used judiciously. That is precisely what Bob Stein, principal of VisiBone, has accomplished with these items. Each one diagrams the syntax for 84 SQL statements and 236 MySQL functions and operators. In a private communication, Mr. Stein noted that no fewer than 194 of MySQL's 225 reserved words are included. (Of the remaining 31 reserved words, 7 are apparently not used anywhere in MySQL, 13 are quite obscure, and 11 are functionally synonymous with other terms — mostly column types from other database engines.)
Given the small amount of space available, there would be the danger of the material being difficult to read. Fortunately, Mr. Stein utilized shades of gray, white and black, blue (to indicate MySQL statements that are not standard ISO/ANSI), and the occasional red (to indicate the most commonly needed information). He also made full use of space on the right hand side of each page, for the largest sidebars, and the remaining space in the middle, for more modestly sized topics. Lastly, he chose a readable type size of 9 points.
The MySQL Cards present the SQL statements and MySQL functions separately, each on their own cards, in alphabetical order. The SQL statements are less horizontally linear and more diagrammatic, to indicate alternative and optional keywords. For each function, the return data type and parameters are given, as well as a pithy summary of what the function does, or an illustrative example. There are a total of 182 examples of the functions and operators, all tested.
The MySQL Chart includes the identical information provided by the cards, but with all of the SQL statements listed down the left-hand side, and all of the MySQL functions down the right-hand side.
Reviews of technical materials oftentimes focus exclusively on the product itself, with no mention as to its delivery. That might make sense for a technical book that could be ordered, packaged, and shipped from any one of many online bookstores, or purchased in person at a local bricks-and-mortar bookstore. In contrast, these MySQL products, like all other VisiBone products, are packaged and shipped from the company's only location, in Brunswick, Maine. The smaller size of such an operation allows for greater attention to each individual shipment. Furthermore, the cards are mailed in sturdy cardboard flats, with directions not to be bent. Charts are mailed in double-hulled cardboard tubes that are even more sturdy.
It is rare that one encounters such excellent products in the fast-paced world of technical publishing. However, I can offer just two minor suggestions for improvement. Even though the color choices generally work quite well, the medium gray used as the background color is probably not the best choice, since almost all of the text is in black. A lighter shade of gray — perhaps that used for a couple of the sidebars, such as "GROUP_CONCAT()" — with a corresponding change in those sidebars, would make the text stand out more.
The only other weakness I found was the use of the term "Habitat," as an adjective for "Shell," "PHP," and "Web Browser." The meaning may be immediately obvious to those of greater intelligence than myself (not that that narrows the field), but my presumption was not confirmed until I saw mention of the term on the aforesaid Web site. The term "Sample" would be more clear.
The chart is the ideal size for a poster, and the 8.5"x11" cards work well; but if the cards were folded into two or three panels, they would be easier to stand up on a desk, and not get buried underneath papers and books.
Nonetheless, the overall quality of these cards and charts is outstanding; the information they offer is accurate, up-to-date, and neatly presented; the protective packaging was appreciated. Even the levity was a nice touch: Despite the limited unused space on the cards, Mr. Stein manages to still squeeze in a bit of humor concerning ISBN bar codes.
Looking over these materials would, for anyone non-technical, probably cause their eyes to glaze over. But for the dedicated MySQL programmer, it can be a humbling experience, largely because it reveals just how little of the language is known or used on a regular basis — by most database programmers, or, at least, by this one. Slowly perusing the information-rich pages, I found myself delighted to discover for the first time functions and statements that would allow my future MySQL code to do more natively, within uncompiled statements, stored procedures, and triggers, without resorting to performing the processing within PHP or whatever other application language will be used.
Lastly, each shipment is accompanied by a letter from Mr. Stein, in which expresses to the customer his appreciation for their order, and his genuine excitement in the potential that any developer has to use his tools to help develop something great. He makes clear that the focus of his efforts is to create "visualization technology for web designers" that will help them do their job better.
Although these items are not books, the VisiBone MySQL Cards and Charts could easily replace the typical MySQL reference book for most occasions when a question of language syntax needs to be resolved as quickly and conveniently as possible. I especially recommend the MySQL Cards, not only for the wealth of information, but for the way that it put all of it "at mental fingertip reach."

MySQL Stored Procedure Programming
Michael J. Ross writes "MySQL may be the most popular open source relational database management system (RDBMS) in the world, but during the first decade of its existence, it lacked support for stored programs, i.e., store procedures, functions, and triggers. The major commercial RDBMS vendors — including Oracle, IBM, and Microsoft — could point to this deficiency as reason enough to choose their proprietary systems over MySQL or any other open source system, such as PostgreSQL. But with the release of MySQL version 5.0, in October 2005, the "little database engine that could" dramatically improved its position against the competition. The most comprehensive discussion of these new capabilities is in the book MySQL Stored Procedure Programming." Read below for the rest of Michael's review MySQL Stored Procedure Programming author Guy Harrison and Steven Feuerstein pages 636 publisher O'Reilly Media rating 9 reviewer Michael J. Ross ISBN 0596100892 summary A comprehensive guide to developing MySQL stored procedures, functions, and triggers.
Written by Guy Harrison and Steven Feuerstein, and published by O'Reilly Media in March 2006 under the ISBNs 0596100892 and 978-0596100896, this book is the first one to offer database programmers a full discussion of the syntax, usage, and optimization of MySQL stored procedures, stored functions, and triggers — which the authors wisely refer to collectively as "stored programs," to simplify the manuscript. Even a year after the introduction of these new capabilities in MySQL, they have received remarkably little coverage by book publishers. Admittedly, there are three such chapters in MySQL Administrator's Guide and Language Reference (2nd Edition), written by some of the developers of MySQL, and published by MySQL Press. Yet this latter book — even though published a month after O'Reilly's — devotes fewer than 50 pages to stored programs, and the material is not in the printed book itself, but in the "MySQL Language Reference" part, on the accompanying CD. That material, in conjunction with the online reference documentation, may be sufficient for the more simple stored program development needs. But for any MySQL developer who wishes to understand in-depth how to make the most of this new functionality in version 5.0, they will likely need a much more substantial treatment — and that's exactly what Harrison and Feuerstein have created.
The authors are generous in both the technical information and development advice that they offer. The book's material spans 636 pages, organized into 23 chapters, grouped into four parts, followed by an index. The first part, "Stored Programming Fundamentals," provides an introduction and then a tutorial, both taking a broad view of MySQL stored programs. The remaining four chapters cover language fundamentals; blocks, conditional statements, and iterative programming; SQL; and error handling. The book's second part, "Stored Program Construction," may be considered the heart of the book, because its five chapters present the details of creating stored programs in general, using transaction management, using MySQL's built-in functions, and creating one's own stored functions, as well as triggers. The third part, "Using MySQL Stored Programs and Applications," explains some of the advantages and disadvantages of stored programs, and then illustrates how to call those stored programs from source code written in any one of five different programming languages: PHP, Java, Perl, Python, and Microsoft.NET. In the fourth and final part, "Optimizing Stored Programs," the authors focus on the security and tuning of stored programs, tuning SQL, optimizing the code, and optimizing the development process itself.
This is a substantial book, encompassing a great deal of technical as well as advisory information. Consequently, no review such as this can hope to describe or critically comment upon every section of every chapter of every part. Yet the overall quality and utility of the manuscript can be discerned simply by choosing just one of the aforesaid Web programming languages, and writing some code in that language to call some MySQL stored procedures and functions, to get results from a test database — and developing all of this code while relying solely upon the book under review. Creating some simple stored procedures, and calling them from some PHP and Perl scripts, demonstrated to me that MySQL Stored Procedure Programming contains more than enough coverage of the topics to be an invaluable guide in developing the most common functionality that a programmer would need to implement.
The book appears to have very few aspects or specific sections in need of improvement. The discussion of variable scoping, in Chapter 4, is too cursory (no database pun intended). In terms of the book's sample code, I found countless cases of inconsistency of formatting — specifically, operators such as "||" and "=" being jammed up against their adjacent elements, without any whitespace to improve readability. These minor flaws could be easily remedied in the next edition. Some programming books make similar mistakes, but throughout their text, which is even worse. Fortunately, most of the code in this book is neatly formatted, and the variable and program names are generally descriptive enough.
Some of the book's material could have been left out without great loss — thereby reducing the book's size, weight, and presumably price. The two chapters on basic and advanced SQL tuning contain techniques and recommendations covered with equal skill in other MySQL books, and were not needed in this one. On the other hand, sloppy developers who churn out lamentable code might argue that the last chapter, which focuses on best programming practices, could also be excised; but those are the very individuals who need those recommendations the most.
Fortunately, the few weaknesses in the book are completely overwhelmed by its positive qualities, of which there are many. The coverage of the topics is quite extensive, but without the repetition often seen in many other technical books of this size. The explanations are written with clarity, and provide enough detail for any experienced database programmer to understand the general concepts, as well as the specific details. The sample code effectively illustrates the ideas presented in the narration. The font, layout, organization, and fold-flat binding of this book, all make it a joy to read — as is characteristic of many of O'Reilly's titles.
Moreover, any programming book that manages to lighten the load of the reader by offering a touch of humor here and there, cannot be all bad. Steven Feuerstein is the author of several well-regarded books on Oracle, and it was nice to see him poke some fun at the database heavyweight, in his choice of sample code to demonstrate the my_replace() function: my_replace( 'We love the Oracle server', 'Oracle', 'MySQL').
The prospective reader who would like to learn more about this book, can consult its Web page on O'Reilly's site. There they will find both short and full descriptions, confirmed and unconfirmed errata, a link for writing a reader review, an online table of contents and index, and a sample chapter (number 6, "Error Handling"), in PDF format. In addition, the visitor can download all of the sample code in the book (562 files) and the sample database, as a mysqldump file.
Overall, MySQL Stored Procedure Programming is adeptly written, neatly organized, and exhaustive in its coverage of the topics. It is and likely will remain the premier printed resource for Web and database developers who want to learn how to create and optimize stored procedures, functions, and triggers within MySQL.

MySQL Stored Procedure Programming
Michael J. Ross writes "MySQL may be the most popular open source relational database management system (RDBMS) in the world, but during the first decade of its existence, it lacked support for stored programs, i.e., store procedures, functions, and triggers. The major commercial RDBMS vendors — including Oracle, IBM, and Microsoft — could point to this deficiency as reason enough to choose their proprietary systems over MySQL or any other open source system, such as PostgreSQL. But with the release of MySQL version 5.0, in October 2005, the "little database engine that could" dramatically improved its position against the competition. The most comprehensive discussion of these new capabilities is in the book MySQL Stored Procedure Programming." Read below for the rest of Michael's review MySQL Stored Procedure Programming author Guy Harrison and Steven Feuerstein pages 636 publisher O'Reilly Media rating 9 reviewer Michael J. Ross ISBN 0596100892 summary A comprehensive guide to developing MySQL stored procedures, functions, and triggers.
Written by Guy Harrison and Steven Feuerstein, and published by O'Reilly Media in March 2006 under the ISBNs 0596100892 and 978-0596100896, this book is the first one to offer database programmers a full discussion of the syntax, usage, and optimization of MySQL stored procedures, stored functions, and triggers — which the authors wisely refer to collectively as "stored programs," to simplify the manuscript. Even a year after the introduction of these new capabilities in MySQL, they have received remarkably little coverage by book publishers. Admittedly, there are three such chapters in MySQL Administrator's Guide and Language Reference (2nd Edition), written by some of the developers of MySQL, and published by MySQL Press. Yet this latter book — even though published a month after O'Reilly's — devotes fewer than 50 pages to stored programs, and the material is not in the printed book itself, but in the "MySQL Language Reference" part, on the accompanying CD. That material, in conjunction with the online reference documentation, may be sufficient for the more simple stored program development needs. But for any MySQL developer who wishes to understand in-depth how to make the most of this new functionality in version 5.0, they will likely need a much more substantial treatment — and that's exactly what Harrison and Feuerstein have created.
The authors are generous in both the technical information and development advice that they offer. The book's material spans 636 pages, organized into 23 chapters, grouped into four parts, followed by an index. The first part, "Stored Programming Fundamentals," provides an introduction and then a tutorial, both taking a broad view of MySQL stored programs. The remaining four chapters cover language fundamentals; blocks, conditional statements, and iterative programming; SQL; and error handling. The book's second part, "Stored Program Construction," may be considered the heart of the book, because its five chapters present the details of creating stored programs in general, using transaction management, using MySQL's built-in functions, and creating one's own stored functions, as well as triggers. The third part, "Using MySQL Stored Programs and Applications," explains some of the advantages and disadvantages of stored programs, and then illustrates how to call those stored programs from source code written in any one of five different programming languages: PHP, Java, Perl, Python, and Microsoft.NET. In the fourth and final part, "Optimizing Stored Programs," the authors focus on the security and tuning of stored programs, tuning SQL, optimizing the code, and optimizing the development process itself.
This is a substantial book, encompassing a great deal of technical as well as advisory information. Consequently, no review such as this can hope to describe or critically comment upon every section of every chapter of every part. Yet the overall quality and utility of the manuscript can be discerned simply by choosing just one of the aforesaid Web programming languages, and writing some code in that language to call some MySQL stored procedures and functions, to get results from a test database — and developing all of this code while relying solely upon the book under review. Creating some simple stored procedures, and calling them from some PHP and Perl scripts, demonstrated to me that MySQL Stored Procedure Programming contains more than enough coverage of the topics to be an invaluable guide in developing the most common functionality that a programmer would need to implement.
The book appears to have very few aspects or specific sections in need of improvement. The discussion of variable scoping, in Chapter 4, is too cursory (no database pun intended). In terms of the book's sample code, I found countless cases of inconsistency of formatting — specifically, operators such as "||" and "=" being jammed up against their adjacent elements, without any whitespace to improve readability.

MySQL Pocket Reference
Michael J. Ross writes "MySQL database administrators and developers have several options for MySQL reference sources, though naturally none of them are ideal in all situations. The online MySQL documentation is extensive, but the most commonly needed nuggets are buried in its necessarily exhaustive contents. Third-party MySQL reference books can winnow out some of the rarely-used minutia, but they still encompass hundreds of pages, reflecting the complexity of the subject. For quickly looking up the most frequently used command syntax and other details, a MySQL user would usually be best served by a much more compact book, such as MySQL Pocket Reference." Read below for the rest of Michael's review. MySQL Pocket Reference author George Reese pages 96 publisher O'Reilly rating 9 reviewer Michael J. Ross ISBN 059600446X summary Great for quickly looking up the most frequently used command syntax and other details of MySQL
Written by George Reese, this book was published by O'Reilly Media, in February 2003. It may span only 96 pages, and weigh only 3.2 ounces, but it packs a substantial amount of useful information into a diminutive form. The book's material is organized into several sections, covering MySQL installation, command-line tools, data types, SQL, operators, functions, and table types.
After presenting a quick introduction and some other housekeeping topics, the author briefly explains how to install, configure, and start up MySQL, as well as how to set the root password. This RDBMS includes a dozen command-line tools, and the author next provides the briefest of summaries for each one, and more details on the most commonly used one, mysql.
The next four sections compose the meat of the book, as they cover the MySQL data types, SQL query language, operators, and functions. Of all the aspects of any programming language or RDBMS, the one that frequently causes the most confusion — and for which a handy reference guide would be most appreciated — is the proper use of data types. In MySQL Pocket Reference, the author presents all of the MySQL data types, grouped into numerics, strings, dates, and complex types. For each data type, the author shows the declaration syntax, the storage space required, and the purpose of the data type.
MySQL version 4.0 supports ANSI SQL 92, as well as some proprietary extensions, which is true for most if not all substantial RDBMSs. Reese explains the case sensitivity of MySQL for various contexts; the use of literals, including escape sequences; the rules concerning identifier naming and aliasing; and how to insert comments in your code. Much more space is devoted to all of the MySQL commands, ranging from ALTER TABLE to USE. For each command, the reader is shown the syntax, including optional keywords, clauses, and other elements, as well as a generous number of illustrative examples.
The last three sections of the book cover operators (arithmetic, comparison, and logical), functions (aggregate and otherwise), and table types. The section on functions will likely get a lot of use from the average reader, as it is relatively easy to forget the name and parameter list of any function — particularly if it has not been used by the developer for some time, and is not present in the surrounding code.
Like any pocket reference book, this one is not intended to serve as a full reference source or as a MySQL tutorial — of which O'Reilly offers several. Rather, it is best used for quickly answering questions concerning command syntax, operator precedence, function parameter order, or any of the other MySQL language details that are not listed automatically by programming editors, nor otherwise immediately obvious. Yet despite its small size, this book contains information that may be unknown to even some of the most experienced MySQL administrators and programmers. For instance, I had no idea that 2007-04-00 is considered a valid date. (I only wish that my taxes were due on that day.)
O'Reilly Media has a Web page on their site that provides some additional resources related to this book. These include links for reading the reviews offered by other readers, submitting your own review, and checking the errata for the book, of which there are 20, as of this writing — 19 of which have been confirmed.
There appear to be only two flaws in this book. It lacks a list of MySQL reserved words, which is odd for a reference book. Also, the text on every page is set too close to the binding, thus compelling the reader to force open the book more than should be necessary, just to comfortably read the inmost ends of the lines of text. This could be easily fixed in a subsequent edition, by moving the text outwards approximately half a centimeter, since the outer margins are much wider than necessary.
Speaking of editions, because this first edition of the book appeared in early 2003, it covers up to version 4.0 of MySQL. One can only hope that a second edition will be made available at some point in the future, so that it can be brought up to date with all of the new additions to MySQL 5, which are substantial. These include cursors, stored procedures, triggers, and views.
Nonetheless, this first edition would be of value to anyone using MySQL. In essence, MySQL Pocket Reference is neatly organized, extremely portable, and packs much valuable information into a succinct format.

The Book of JavaScript
Michael J. Ross writes "Developers of Web sites, whether professional programmers or Web hobbyists, are oftentimes impressed by the more advanced functionality that can be achieved on a Web page using JavaScript. Yet these personal discoveries of JavaScript's power do not always motivate the developers to implement similar functionality on their own sites — partly because most of those custom-built JavaScript functions are cryptic, and make no attempt to show how the developer would customize the code for their own use. The majority of JavaScript books are of limited help in this regard, because they focus on the language details, illustrated only with code snippets. Many readers would benefit more from instruction via working examples, which is the approach used by The Book of JavaScript." Read the rest of Michael's review.

"thau!," a veteran of the Internet and computer programming — especially JavaScript, which he has taught to countless other programmers, through this book, as well as numerous courses, conference presentations, and the tutorials he has written for Webmonkey.
Published by No Starch Press, the second edition of The Book of JavaScript appeared in December 2006. The publisher maintains a Web page for the book, where visitors can find an online copy of the book's table of contents, excerpts from reader reviews, links for purchasing the paper and electronic versions of the book, a sample chapter ("Chapter 2: Using Variables and Built-In Functions to Update Your Web Pages Automatically") as a PDF file, the errata discovered by the author and readers (several reported so far), and a link to the author's companion site.
Unlike some books' companion sites, this one is worth a visit, and not just to see a working example of the tip box described in chapter 8, which is used to show how to create an array. Thau's site has links for viewing, running, and downloading all of the sample code in the book's figures. In addition, the visitor can obtain copies of the book's JavaScript libraries, for doing cookies, form validation, and plug-in detection. There are links for viewing and downloading the three sample Web sites. However, in his AntWeb site, at least as of this writing, none of the images are showing up on his homepage. Another problem, of much less importance, is the strange behavior of the "Websites" and "Freeware" options on his "Chapters" drop-down list box. Choosing either one takes the visitor to his "Websites" page, but always displays "Freeware" in the drop-down. It is hard to imagine that this behavior is intentional.
The book's material spans 528 pages, most of which is found in 18 chapters, covering a variety of topics: an overview of JavaScript's capabilities, alternatives, and limitations, among other less technical issues; variables and built-in functions; browser detection and simple control flow; rollovers, events, images, and the "document" object; window manipulation and properties; creating your own JavaScript functions; Web forms; arrays and iteration; timing events; frames and image maps; handling form input and strings; cookies; dynamic HTML, CSS, and DOM; AJAX basics; XML; server-side AJAX; a sample application (an online to-do list); and debugging JavaScript and AJAX. The book also offers four appendices: answers to chapter assignments; online resources (tutorials, sample code, AJAX sites, and AJAX frameworks); a complete reference to JavaScript's objects and functions; the code for the book's two longest applications, namely, the Italian translator and the to-do list.
This second edition serves as a follow-up to the well-regarded first edition that came out seven years earlier. Both the book and the language itself have clearly withstood the test of time. There are several reasons for the popularity of that first edition: It taught the language and its capabilities largely through the use of complete JavaScript functions, each of which served as an illustrative example of not just the elements and rules of the language, but also straightforward ways of accomplishing common tasks in JavaScript. After all, looking at sample code is how most programmers prefer to learn or verify how a language works.
The book assumed no prior knowledge of JavaScript or any other computer language, on the part of the reader. This characteristic not only set it apart from the large number of other JavaScript titles published at that time, but it made the book more attractive to people new to programming in general and Web programming in particular. Such readers might also favor this book over others because of the author's approachable writing style, in which he fully explains topics in a leisurely manner, without the terseness seen in most programming language books. This is not to say that brevity in technical works is ever a mistake per se; the busy professional programmer wants to find answers as quickly as possible. But such brevity can quickly prove frustrating to non-techies, who lack the background for understanding terse explanations and for knowing where they can turn for clarification.
All of these laudable attributes of the first edition have been carried over into this latest edition. The primary change found in this second edition, is the coverage of AJAX (asynchronous JavaScript combined with XML). Even though the additional material substantially increases the length of the book, by 124 pages, the end result is still far from unwieldy — mostly due to several factors: The book's table of contents, along with the index, are detailed enough to make it relatively easy to find a particular topic in the book, assuming that it is included. The subsection listings in the table of contents, like good source code, make liberal use of whitespace for readability. In the text itself, coloring the headings and note numbers blue make them stand out.
Aside from the aforesaid problems with the book's companion site, there are a few other areas for improvement: It was noted earlier that the last appendix contains the sample code from chapters 15 and 17. The author states that these code listings were located in an appendix, rather than the chapters themselves, because they are too long. Actually, they comprise only a dozen pages, which would have been better located in the chapters where the reader expects to see them, and where they would be close at hand for referencing. The first listing is only two pages long, and definitely should be located in chapter 15. Even for the second listing, if the author is concerned about readers getting frustrated flipping through the 10 pages to find the continuation of the chapter's discussion, a simple note at the beginning of that code, as to what page the discussion is resumed, would be sufficient.
Some fundamental language elements of JavaScript are introduced fairly late in the book. For instance, it is noted above that an explanation as to how to create an array — an essential concept in just about any procedural language — is not found until the eighth chapter, on page 134. This is more than one third of the way into the book's 18 chapters. On the other hand, given that the author has chosen to present these language concepts, for the most part, only when needed and when describing the sample code, this later introduction of some key concepts might not prove much of a problem to most readers. However, this is a case in which the completeness and accuracy of the book's index, are even more critical than usual. In this regard, the book does not fail the reader, as the index appears to provide enough coverage.
The formatting of the code throughout the text is not entirely consistent, as evidenced by some open braces appearing on their own lines, thus wasting space, and in other cases on the same line as the preceding parenthesized expression, though separated by a pointlessly large number of spaces. Code level blocks are indented two or four spaces, seemingly at random. Continuation lines are indented exactly the same; they would be more clear if they had double the number of spaces as code level blocks. Of more importance to the reader attempting to figure out what code is serving what purpose, there are far too many large chunks of code lacking any comments, which are needed, since much of the code is not self-describing. In most of the functions, the only comment lines are those for hiding the JavaScript from outdated browsers — a practice that should have been phased out in this latest edition.
Any experienced programmer who needs a complete JavaScript reference book, or a book that covers all the language's elements in fine detail, would be best served by choosing a different book from this one. On the other hand, once they had secured such a book, they would likely find David Thau's contribution an enjoyable source of ideas on what can be done using JavaScript capabilities. For anyone who wishes to learn JavaScript in a practical and relaxed way, by reading clearly explained sample projects and their code, should be well pleased with The Book of JavaScript.

The Book of JavaScript
Michael J. Ross writes "Developers of Web sites, whether professional programmers or Web hobbyists, are oftentimes impressed by the more advanced functionality that can be achieved on a Web page using JavaScript. Yet these personal discoveries of JavaScript's power do not always motivate the developers to implement similar functionality on their own sites — partly because most of those custom-built JavaScript functions are cryptic, and make no attempt to show how the developer would customize the code for their own use. The majority of JavaScript books are of limited help in this regard, because they focus on the language details, illustrated only with code snippets. Many readers would benefit more from instruction via working examples, which is the approach used by The Book of JavaScript." Read the rest of Michael's review.

MySQL Cookbook
Michael J. Ross writes "Of all the technical challenges faced by the typical experienced computer programmer, questions about syntax form a relatively small portion. This is especially true now that current coding editors and IDEs offer statement expansion and syntax checking. Rather, the most common type of technical challenge is understanding how to solve a specific data access or manipulation problem. Hence the growing popularity of programming "cookbooks," which are filled with "recipes," each comprising a concise statement of a focused problem, followed by a solution, with plenty of sample code to show how to implement it. For developers using the MySQL database system, the gold standard of such books is MySQL Cookbook, by Paul DuBois." Read below for the rest of Michael's review MySQL Cookbook author Paul DuBois pages 948 publisher O'Reilly Media rating 8 reviewer Michael J. Ross ISBN 059652708X summary A great book for developers using the MySQL database system
Published by O'Reilly Media, the second edition appeared in November 2006. This new edition has been updated for MySQL version 5.0. The publishers have a Web page devoted to the book, where the visitor can find both brief and full descriptions of the book, an online table of contents and index, a sample chapter (number 5, "Working with Strings") in PDF format, errata (none reported as of this writing), and a way to post your own review on the O'Reilly Web site. There are also links for purchasing the book, or reading an online version, in the Safari Bookshelf program.
The bulk of the book's material is divided among 20 chapters, covering a wide range of topics: Using the mysql Client Program; Writing MySQL-Based Programs; Selecting Data from Tables; Table Management; Working with Strings; Working with Dates and Times; Sorting Query Results; Generating Summaries; Obtaining and Using Metadata; Importing and Exporting Data; Generating and Using Sequences; Using Multiple Tables; Statistical Techniques; Handling Duplicates; Performing Transactions; Using Stored Procedures, Triggers, and Events; Introduction to MySQL on the Web; Incorporating Query Results into Web Pages; Processing Web Input with MySQL; Using MySQL-Based Web Session Management.
Most of these chapters contain a generous number of sections, each serving as a recipe for a specific problem within MySQL. Two of the chapters have only four such recipes, but most have a dozen or more, with a few of them boasting more than three dozen recipes. Each recipe begins with a brief problem statement, and usually an equally brief solution statement, followed by a much more lengthy discussion, which contains the actual explanation of the solution, the sample code, and the expected output of that code. Some of the sections conclude with a mention of related recipes that could also be consulted.
This book, like so many other programming cookbooks, is weakened by the practice of offering a "Solution" subsection that consists of only one or two sentences — so terse and high-level that it provides, for all practical purposes, no solution to the reader. The actual solution is found in the "Discussion" subsection, which follows. This practice makes no sense. Because both subsections address the problem solution, they should be combined into a single subsection, naturally labeled "Solution." It appears that the purpose of the current Solution statements is to provide a terse summary. If so, then it should be labeled as such, yet still included within the new Solution subsection.
Despite this illogical division of each solution into two subsections, the content of the problem solutions found in MySQL Cookbook should be quite valuable, for several reasons: Firstly, the author has chosen the sorts of problems, within each category, that the MySQL programmer would typically encounter. No doubt this is a consequence of Paul DuBois being the author of a number of MySQL books, as well as one of the earliest contributors to the online MySQL Reference Manual. Secondly, the solutions work, and have been demonstrated to do so. Thirdly, the writing style is straightforward, which is characteristic of O'Reilly's titles. Fourthly, all of the problem solutions contain sample code and its output, which not only demonstrate the validity of each solution (as noted in my second point), but also allows the reader to see how the solution works simply by reading the material, and not having to type in the sample code to get the output within their own development environment — assuming one is even at hand, when reading the book.
The bulk of MySQL-related code in use today, was created not just to be accessed within a database client program, such as mysql, but instead from interpreted programming languages — especially those used heavily on Web sites. This is one area where MySQL Cookbook really shines, because it contains a large amount of sample code in Perl, PHP, Python, Java, and even Ruby. That is not to say that every code sample in one language has corresponding samples for all of the other languages; that would undoubtedly make the book much longer than it currently is, and probably unwieldy. But in cases where all of the languages are capable of expressing brief solutions, then they are included.
Regardless of whether the reader chooses the print or online versions, there are roughly two ways to make use of this book. If a programmer wishes to significantly increase their knowledge of what MySQL can do for them, and also increase their comfort level with utilizing those capabilities, then they might elect to read the book from stem to stern. Given that this would involve reading over 900 pages, it would certainly take some time for the average developer, but arguably could be time well spent. At the other end of the spectrum, the reader might elect to peruse individual sections that look interesting — particularly if they are relevant to a current project. This approach is certainly doable, because each of the recipes is self-contained, without the cross-referencing seen in many non-recipe style books. Admittedly, there are some "See Also" sections, but they are relatively few in number, with largely optional information, and tend to simply enrich the book's presentation, rather than frustrating the reader by pointing to other areas of the book.
This new edition of MySQL Cookbook concludes with four appendices, and an index. The first appendix explains where to obtain the software for MySQL, the five API programming languages used in the book, and the Apache Web server. The second appendix shows how to execute programs written in those five interface languages, on the command line. The third appendix is a fairly substantial primer on Java Server Pages (JSP) and Tomcat, providing an overview of servlets and JSP, as well as how to install and set up a Tomcat server, the Tomcat directory structure, the basics of JSP pages, and more. The last appendix lists resources outside the book for MySQL and the five aforementioned languages.
Unlike far too many programming books on the market now, this book's index is generally quite thorough, which is essential for a work of this size (975 pages). The recipe titles in the table of contents, are detailed enough to make it possible for the reader to locate the appropriate recipe in the book for their particular problem — assuming the book addresses that problem — and are grouped by subject, making it easier to find related recipes, which oftentimes can provide insight into other problems that they do not address directly.
Despite the obvious effort that has gone into both editions of this book, there are still some areas for improvement, and most of them are related to the readability of the sample code. Admittedly, there are different schools of thought as to optimal coding style, including use of whitespace, the placement of braces, and other matters. This assessment can only be my own opinion, based upon years of reading other people's code. The sample code in MySQL Cookbook would be more readable if more whitespace were utilized to separate function and variable names from open and close parentheses. This is especially true for the SQL code and MySQL extensions, for which all of the keywords are in all uppercase. The code fragments and full programs written in the API languages — such as Perl and PHP — are more readable, though they sometimes suffer from nondescriptive variable names. One might argue that the aforesaid choices are needed to cut down on the space consumed by the code on the book's pages. But if that were true, then the author likely would not have wasted an entire line for each open brace. Last, and certainly not least for the programmer who would like to try out the author's sample code in their own environment, it is unfortunate and inexplicable as to why the sample code is not offered on the O'Reilly Web site for downloading.
All in all, MySQL Cookbook is a well-organized and neatly written work, which should be of tremendous value to any software developer trying to find proven solutions to common database programming problems.

PHP 5 in Practice
Michael J. Ross writes "Computer programming books come in all varieties, but there are at least four general categories: introductory texts, which typically have the lowest content per page; language references, which have become increasingly supplanted by online sources; "advanced" treatments, which are often a mishmash of errata-riddled articles; and "how-to" books, usually at the intermediate level, and sometimes presented as "cookbooks." It is that last category that has been growing in popularity, and for good reason. When an experienced software developer needs assistance, it is rarely for language syntax, but instead a desire to see how someone else solved a specific problem. For solutions using the PHP language, one source of information is PHP 5 in Practice." Read the rest of Michael's review. PHP 5 in Practice author Elliott White III and Jonathan D. Eisenhamer pages 456 publisher Sams Publishing rating 8 reviewer Michael J. Ross ISBN 0672328887 summary One of the most meaty, immediately useful, and fluff-free PHP books available
The book was authored by Elliott White III and Jonathan D. Eisenhamer, and put out in July 2006 by Sams Publishing (an imprint of Pearson Education). Given today's standards of hefty technical books, this particular one is relatively light, weighing in at 456 pages, which are organized into an introduction, numerous chapters, and three appendices.
Its introduction is more interesting than that of most similar books, whose introductions usually consist of formatting conventions and explanations as to why the book was written — all such content providing little to no value to the impatient programmer facing a deadline, and invariably ignored (the content, that is, not the deadline).
White and Eisenhamer took a refreshingly different tack, and chose instead to explain their use of coding standards, comments and whitespace, braces and parentheses, PHP short tags, PHP mode, and other language considerations that are more useful than the typical rundown of somewhat childish icons used in other texts, such as light bulbs and red warning signs.
Switching to the other end of the book, we find three appendices. The first one briefly discusses issues one might face in migrating from PHP version 4 to 5. The second introduces the Standard PHP Library (SPL), and the objects related to its primary design pattern, the Iterator. The third appendix discusses what composes the bulk of output from my PHP programs: error messages. Seriously, this appendix is worth reading, if only for the suggestions as to what to look for when you encounter some of the most common PHP error messages.
The bulk of the book's material is divided into 20 chapters, which are themselves divided into two parts: PHP internals, and applications. The internals are: strings, numbers, time and date, variables, arrays, functions, classes and objects, and files and directories. Starting off with a discussion of strings, might seem odd to the neophyte programmer, but to the veteran who has had to learn several languages during their career, the choice makes a lot of sense. There must be countless developers out there who, being fluent in the C language and object-oriented concepts, jumped into writing their first C++ program, and had to hit the books for the first time when they wanted to do some non-array-based string handling.
The book's second part covers some of the most common applications in PHP programming: Web page creation (using XHTML and CSS), Web form handling, data validation and standardization, sessions and user tracking, Web services and other protocols, relational databases and other data storage methods, e-mail, XML, images, error reporting and debugging, and user authentication and encryption. That last chapter, in the next edition, should be relocated so that it precedes or follows the chapter on sessions and user tracking.
Many of the chapters begin with a "Quick Hits" section, which briefly summarizes how to perform many of the most common and essential tasks related to that chapter's topic. For instance, in the chapter covering the use of variables, this first section explains how to: check if a variable has no value or if it is empty (not synonymous in PHP), undefine a variable, cast it to a certain data type, and do the same thing for a value. There is one minor erratum that should be noted: On page 71, in the first "Quick Hit," it reads "a variable has bee. given a value." ("been"'s "n" ended too soon.)
Each section within the chapter briefly explains the problem domain, and then presents sample code to solve the given problem. The code itself is fairly well commented, and the variable names are adequately descriptive (unlike in some programming books, whose coding standards border on the criminal).
All in all, the book offers a lot of worthwhile solutions to a wide range of problems, and does so in a straightforward manner. It is for this reason that it is not evident as to why this particular PHP title has received so little notice. For instance, on Amazon.com, it has received only one reader review, as of this writing, and does not even make it into the top quarter million books ranked in sales by Amazon.com. It is a pity, because the book deserves much more attention.
Even though this book is to be recommended, and is packed with code and text that are well worth studying, it has one unmistakable weakness for which this writer can think of no adequate justification. The book contains almost no illustrations, even when they are clearly called for — in fact, especially in those cases. For instance, the section that shows how to generate a calendar, does not show a calendar! The code is present, but the sample output — which is what the poor reader would appreciate, to see the results of the code — is missing.
Granted, an absence of figures and screenshots might be understandable for the first part of the book, which covers the PHP language itself. But the second part, covering applications, has far too many unillustrated PHP scripts. These include sections focusing on drop-down menus, progress bars, and graphical charts Web forms. In the last chapter, there is a section with code that generates captchas, but the reader is not shown what they look like. The entire 18th chapter is devoted to images, but contains not a single one! I cannot imagine why the authors and/or publisher chose to leave out these essential graphics. Was it to save money? Whatever the reason, it was a significant mistake, and one that should be corrected in the next edition.
Readers who agree with this assessment, or who have other thoughts concerning this otherwise excellent book, can leave feedback via the book's Web page on the Web site for Sams Publishing. This page offers details on the book, a description and table of contents, links for requesting instructor or review copies, and a tool for searching the book's contents within the Safari online technical library. The book's introduction states that the Web site hosts all of the code listings, as well as a list of errata. Yet, I was unable to find either one. (Sadly, the Pearson Education sites are still some of the least usable in the technical book publishing world.) Much better results were obtained on Eli White's site.
Despite an inexcusable and almost complete lack of needed illustrations, PHP 5 in Practice is possibly one of the most meaty, immediately useful, and fluff-free PHP books available. No serious PHP programmer should be without it.

PHP 5 in Practice
Michael J. Ross writes "Computer programming books come in all varieties, but there are at least four general categories: introductory texts, which typically have the lowest content per page; language references, which have become increasingly supplanted by online sources; "advanced" treatments, which are often a mishmash of errata-riddled articles; and "how-to" books, usually at the intermediate level, and sometimes presented as "cookbooks." It is that last category that has been growing in popularity, and for good reason. When an experienced software developer needs assistance, it is rarely for language syntax, but instead a desire to see how someone else solved a specific problem. For solutions using the PHP language, one source of information is PHP 5 in Practice." Read the rest of Michael's review. PHP 5 in Practice author Elliott White III and Jonathan D.

CSS: The Definitive Guide
Michael J. Ross writes "Every Web developer knows that Cascading Style Sheets (CSS) makes it possible to separate the contents of Web pages from the styling of the elements on those pages. This in turn confers tremendous advantages, such as allowing site-wide changes of appearance to be made just once, in a single stylesheet file, rather than in all of the pages containing the affected elements. The syntax and proper usage of CSS is not as simple as implied by many HTML/CSS books, most of which fail to provide enough detail as to how CSS is applied to page elements. Web developers relying upon these books soon find themselves hitting those limits, and becoming frustrated when trying to debug Web pages. CSS: The Definitive Guide, authored by CSS expert Eric A. Meyer, aims to fill that gap." Read on for the rest of Michael's review. CSS: The Definitive Guide author Eric A. Meyer pages 536 publisher O'Reilly Media rating 9 reviewer Michael J. Ross ISBN 0596527330 summary A comprehensive CSS reference guide.
Published by O'Reilly Media in November 2006, this title is now in its third edition. The first edition appeared in May 2000, and the second in January 2004 — with each one establishing the book as an immediate favorite among hard-core Web programmers. Each revision brought it up to date with the evolution of CSS as a standard, its support among the most popular Web browsers, and its usage within the Web development community. This latest edition covers CSS2 and CSS2.1, but does not include the CSS3 modules, including those that have reached Candidate Recommendation status, because their implementation is largely incomplete among most of the browsers.
Web veteran Eric Meyer presents the book's material in a methodical manner, starting with an overview of CSS's purpose and advantages, and quickly moving into the details of the technology: selectors, structure, inheritance, values, units, fonts, text properties, visual formatting, padding, borders, margins, colors, backgrounds, floating, positioning, tables, lists, and generated content (e.g., bullets of unordered lists). The last two chapters address user interface styles (system fonts and colors, cursors, and outlines) and non-screen media (such as paged and aural content). The book's 536 pages are organized into a total of 14 chapters and three appendices. The first appendix is a complete CSS property reference, spanning more than 40 pages, with visual, page, and aural properties grouped separately. For each property, Meyer explains its purpose, its valid values, the initial value, what elements it applies to, whether it is inherited, its computed value, and additional notes (if any). The second appendix is a reference for the selectors, pseudo classes, and pseudo elements. The third and final appendix is much shorter than the first two, but no less interesting, as it discusses a sample HTML 4 stylesheet, which is presented in the CSS2.1 specification as the recommended style sheet for developers to use.
As with all of their other titles, O'Reilly Media offers a Web page devoted to this book, where visitors will find links to online versions of the book cover, table of contents, index, registration form, reader reviews, and errata (of which there are none, as of this writing). In addition, the page has offers to receive a volume discount, and to read the book online as part of O'Reilly's Safari service.
Anyone who is considering purchasing this book might initially be concerned by the dearth of feedback on the Web sites of the publisher and the major online booksellers — in the form of few reader comments, and no reported errata. The prospective reader may wrongly conclude that this indicates a lack of interest in the book, and thus it must be unpopular — probably for good reason. But just the opposite is true, as demonstrated by the book's sales rank on Amazon.com alone: #4631, as of this writing. Unlike far too many of the other HTML/CSS books available, this one does not engender scathing reviews by customers angry with the books' shoddy writing and sloppy mistakes. Rather, Meyer's contribution is the type of solid reference book that the discerning Web developer will quietly place on their desk or bookshelf, within easy and frequent reach — possibly displacing a dog-eared first or second edition of the same title. Furthermore, the absence of errata should suggest that most if not all kinks have been worked out of the book, and not that the book is failing to receive careful readings.
CSS: The Definitive Guide benefits not just from its multiple revisions, but also from Eric Meyer's clear and complete writing style. Unlike his more advanced books, this one is far more approachable, making it possible for the reader to easily jump into the midst of any topic and quickly pick up the thread — as is essential for any technical reference work. The theoretical discussions and the sample code demonstrate his abundant experience in using CSS in the real world, discovering or verifying its idiosyncrasies, and pushing it to its limits. Most of the critical visual and positioning topics are well illustrated with diagrams and sample output, few of which are weakened by the lack of color in the grayscale figures. Last and certainly not least, readers should be pleased that the book's material has been updated for Internet Explorer 7, which promises to fix many inexcusable problems in earlier versions of the browser.
Rarely does one come across a programming book that has no significant flaws, and will likely become a favorite resource for developers everywhere. CSS: The Definitive Guide is a comprehensive, well-written, and welcome addition to the library of any Web developer who wishes to understand and utilize CSS better.

CSS Cookbook
Michael J. Ross writes "Anyone involved with the coding of Web sites likely knows that Cascading Style Sheets (CSS) should be used for styling the content of their sites' pages — setting text sizes and fonts, setting background colors, sizing margins, positioning images, and more. CSS allows the Web developer to specify the visual appearance of the site, separately from the HTML, and thus to be able to make changes in the future within a single stylesheet, rather than hunting through the HTML and modifying every occurrence of each affected element. The benefits of CSS are many, but so too can be the frustrations when the developer turns for help to CSS books heavy on theory and light on practical explanations. For every Web site 'cook' feeling the heat in their cyber kitchen, there is an ingredient that can help: CSS Cookbook." Read the rest of Michael's review, CSS Cookbook author Christopher Schmitt pages 538 publisher O'Reilly Media rating 8 reviewer Michael J. Ross ISBN 0596005768 summary Practical solutions to common CSS challenges
Written by award-winning Web designer Christopher Schmitt, this book is published by O'Reilly Media, under the ISBN 0596005768, and is in its second edition, having been updated for Internet Explorer 7 and Firefox 1.5. The book has its own Web page on the publisher's site, offering the book's table of contents, the index, Appendix D ("Styling of Form Elements," in PDF format), and links for reading and submitting book reviews/comments, as well as reading and reporting errata (there are none, as of this writing).
The book's 538 pages are organized into 12 chapters, which cover the major areas of interest to the Web developer: CSS overview, typography, images, page elements, lists, links and navigation, forms, tables, page layouts, printable pages, hacks and workarounds, and design considerations. Appendix A briefly describes some of the better online CSS resources, including tutorials, design guides, discussion groups, technical references, and tools, such as the W3C validators. The next two appendices cover CSS 2.1 properties, proprietary extensions, selectors, pseudo-classes, and pseudo-elements.
The fourth and last appendix, on the styling of form elements, details how 20 CSS properties affect eight form elements, as displayed within Windows Internet Explorer 5, 5.5, 6, and 7; Mac Safari 2; Windows and Mac Firefox 1.5; Windows and Mac Netscape Navigator 7.2; and Opera 8.5. The form elements considered are: checkboxes, file upload elements, radio buttons, text fields, multiple options, select elements, submit buttons, and text areas. The author does not explain exactly what page elements are meant by "File Upload" (at the beginning of the appendix) or "File Input" (the actual section title). Presumably he is referring to the file display field and Browse button, and not the file locator dialog box, which is determined by the browser and operating system. More importantly, he does not explain what is meant by "multiple options" nor "select elements," and neither term is listed in the book's index. Future editions of the book would benefit by beginning every element's section with an example, showing the code as well as the element's appearance on a Web page. Despite this obvious omission, this appendix could prove a godsend to anyone concerned with how these various types of elements are affected by CSS within these eight major browser versions. As noted earlier, the appendix can be downloaded for free.
HTML/CSS books generally fall into two broad categories: Introductory books are usually sufficient for beginners, because they cover the basics. But they are typically useless to the veteran developer who is struggling to understand why Internet Explorer is mucking up yet another page that looks fine in Firefox, Opera, and Safari — and how to work around the problem. Advanced books assume that the reader already has a relatively solid understanding of the technologies, and uses that basis as a foundation from which to explore sophisticated design techniques. But even those books prove inadequate for the developer who is simply wondering how to best use pure CSS to do such presumably straightforward tasks as positioning some images horizontally, with small captions centered underneath each one. In fact, many of those advanced books seem to have little interest in clearly explaining how the reader can do what the author has done, largely because the sample projects and their source listings are too long and involved, thus burying the critical HTML and CSS in pages of code.
There is clearly a great need for one or more HTML/CSS books aimed at the developer who already understands the basics, and wants to apply that knowledge for building robust Web pages, all while following defensible best practices. The O'Reilly "Cookbook" titles are intended to fill that gap, by presenting the material in the form of recipes, each comprising a brief statement of the problem to be solved, a summary of the solution, and a discussion of the solution's details. Oftentimes additional resources are referenced, in a "Sea Also" subsection, which might have one or more links to relevant Web sites. The discussion subsections usually have sample code, in addition to a figure showing the code's output.
Possibly the greatest benefits of the cookbook format, is that it forces the author to clearly state the purpose of each section, and then to get right to the point of how to achieve that purpose. This prevents the meandering seen in many of the advanced design books, which is the main reason why they can be so frustrating for the developer who wants to quickly find out how to perform a specific task on a Web page, such as the image positioning task mentioned earlier. Possibly the biggest downside to the cookbook format is that it results in contrived problem statements, such as the very first one in CSS Cookbook: "Problem — You want to use CSS in your web pages." Is that truly a problem? Is it not much more a goal or task, than some sort of problematic difficulty?
Yet aside from any misleading subsection titling, the recipe format does cause any (largely) expository material in a technical book to get chopped up into somewhat artificial pieces. It is more noticeable in the first chapter of this particular book, titled "General," in which Schmitt explains the fundamentals of CSS: selectors, classes and IDs, properties, the box model, style sheets, comments, shorthand properties, floating images, absolute and relative positioning, and using CSS with the more common page development tools. As the author gets into more advanced topics — for which individual subsections can stand more on their own — the recipe format works fine. One advantage is that the section titles end up being detailed enough that the reader can, in most cases, quickly find the relevant section to address their needs.
Overall, this book is a fine addition to O'Reilly's growing list of programming titles. However, like all books, it is not perfect. It does not cover all of the more common tasks that the average Web programmer might want to accomplish — but it does hit the bulk of them. Sadly, all of the figures in the book are in black and white, including those displaying colors on the sample Web pages. Shades of gray are just not optimal. Fortunately, in most cases, the crux of the technique is discernible. In addition, the sample code has too many instances where layout is achieved using tables, and not pure CSS. Lastly, the book's index — similar to that of so many other technical books nowadays — could certainly use some beefing up. After all, if the reader cannot find the desired material using the table of contents, the index is their last hope, before resorting to time-wasting page flipping.
In terms of HTML and CSS information, the topics are well chosen, and the coverage of browser hacks and workarounds is excellent. Also, the most critical parts of the code are helpfully bolded. For those readers completely unfamiliar with JavaScript, it is used only where unavoidable. The book's material is neatly presented, and the author's writing style is straightforward and approachable.
On balance, CSS Cookbook is to be recommended to any developer looking for a CSS guide that is concise, clearly written, well-illustrated, and addresses the most common challenges in building Web pages.

The book's 538 pages are organized into 12 chapters, which cover the major areas of interest to the Web developer: CSS overview, typography, images, page elements, lists, links and navigation, forms, tables, page layouts, printable pages, hacks and workarounds, and design considerations. Appendix A briefly describes some of the better online CSS resources, including tutorials, design guides, discussion groups, technical references, and tools, such as the W3C validators. The next two appendices cover CSS 2.1 properties, proprietary extensions, selectors, pseudo-classes, and pseudo-elements.
The fourth and last appendix, on the styling of form elements, details how 20 CSS properties affect eight form elements, as displayed within Windows Internet Explorer 5, 5.5, 6, and 7; Mac Safari 2; Windows and Mac Firefox 1.5; Windows and Mac Netscape Navigator 7.2; and Opera 8.5. The form elements considered are: checkboxes, file upload elements, radio buttons, text fields, multiple options, select elements, submit buttons, and text areas. The author does not explain exactly what page elements are meant by "File Upload" (at the beginning of the appendix) or "File Input" (the actual section title). Presumably he is referring to the file display field and Browse button, and not the file locator dialog box, which is determined by the browser and operating system. More importantly, he does not explain what is meant by "multiple options" nor "select elements," and neither term is listed in the book's index. Future editions of the book would benefit by beginning every element's section with an example, showing the code as well as the element's appearance on a Web page. Despite this obvious omission, this appendix could prove a godsend to anyone concerned with how these various types of elements are affected by CSS within these eight major browser versions. As noted earlier, the appendix can be downloaded for free.
HTML/CSS books generally fall into two broad categories: Introductory books are usually sufficient for beginners, because they cover the basics. But they are typically useless to the veteran developer who is struggling to understand why Internet Explorer is mucking up yet another page that looks fine in Firefox, Opera, and Safari — and how to work around the problem. Advanced books assume that the reader already has a relatively solid understanding of the technologies, and uses that basis as a foundation from which to explore sophisticated design techniques. But even those books prove inadequate for the developer who is simply wondering how to best use pure CSS to do such presumably straightforward tasks as positioning some images horizontally, with small captions centered underneath each one. In fact, many of those advanced books seem to have little interest in clearly explaining how the reader can do what the author has done, largely because the sample projects and their source listings are too long and involved, thus burying the critical HTML and CSS in pages of code.
There is clearly a great need for one or more HTML/CSS books aimed at the developer who already understands the basics, and wants to apply that knowledge for building robust Web pages, all while following defensible best practices. The O'Reilly "Cookbook" titles are intended to fill that gap, by presenting the material in the form of recipes, each comprising a brief statement of the problem to be solved, a summary of the solution, and a discussion of the solution's details. Oftentimes additional resources are referenced, in a "Sea Also" subsection, which might have one or more links to relevant Web sites. The discussion subsections usually have sample code, in addition to a figure showing the code's output.
Possibly the greatest benefits of the cookbook format, is that it forces the author to clearly state the purpose of each section, and then to get right to the point of how to achieve that purpose. This prevents the meandering seen in many of the advanced design books, which is the main reason why they can be so frustrating for the developer who wants to quickly find out how to perform a specific task on a Web page, such as the image positioning task mentioned earlier. Possibly the biggest downside to the cookbook format is that it results in contrived problem statements, such as the very first one in CSS Cookbook: "Problem — You want to use CSS in your web pages." Is that truly a problem? Is it not much more a goal or task, than some sort of problematic difficulty?
Yet aside from any misleading subsection titling, the recipe format does cause any (largely) expository material in a technical book to get chopped up into somewhat artificial pieces. It is more noticeable in the first chapter of this particular book, titled "General," in which Schmitt explains the fundamentals of CSS: selectors, classes and IDs, properties, the box model, style sheets, comments, shorthand properties, floating images, absolute and relative positioning, and using CSS with the more common page development tools. As the author gets into more advanced topics — for which individual subsections can stand more on their own — the recipe format works fine. One advantage is that the section titles end up being detailed enough that the reader can, in most cases, quickly find the relevant section to address their needs.
Overall, this book is a fine addition to O'Reilly's growing list of programming titles. However, like all books, it is not perfect. It does not cover all of the more common tasks that the average Web programmer might want to accomplish — but it does hit the bulk of them. Sadly, all of the figures in the book are in black and white, including those displaying colors on the sample Web pages. Shades of gray are just not optimal. Fortunately, in most cases, the crux of the technique is discernible. In addition, the sample code has too many instances where layout is achieved using tables, and not pure CSS. Lastly, the book's index — similar to that of so many other technical books nowadays — could certainly use some beefing up. After all, if the reader cannot find the desired material using the table of contents, the index is their last hope, before resorting to time-wasting page flipping.
In terms of HTML and CSS information, the topics are well chosen, and the coverage of browser hacks and workarounds is excellent. Also, the most critical parts of the code are helpfully bolded. For those readers completely unfamiliar with JavaScript, it is used only where unavoidable. The book's material is neatly presented, and the author's writing style is straightforward and approachable.
On balance, CSS Cookbook is to be recommended to any developer looking for a CSS guide that is concise, clearly written, well-illustrated, and addresses the most common challenges in building Web pages.

Deliver First Class Web Sites
Michael J.

These best practices take the form of bookmarked Web pages, saved articles, downloaded PDF files, scribbled notes on scraps of paper, and hastily created documents that will be better organized one of these days, when the developer's schedule becomes less hectic (sure...).

What the developer needs is a book that brings together as many of these best practices as possible, without being overwhelming. Deliver First Class Web Sites: 101 Essential Checklists may be the answer." Read the rest of Michael's review. Deliver First Class Web Sites author Shirley Kaiser pages 331 publisher SitePoint rating 8 reviewer Michael J. Ross ISBN 0975841904 summary A collection of Web site development best practices.
Authored by Shirley Kaiser, this book was published by SitePoint in July 2006, under the ISBN 0975841904. The publisher maintains a Web page devoted to the book, where visitors will find the book's table of contents online, a free preview (chapters 6, 12, and 14, in PDF format), editorial and customer reviews, a link to download all of the checklists (also in PDF) for all customers, links and an FAQ for ordering directly from SitePoint, and errata (none reported, as of this writing). The fact that SitePoint is willing to allow readers to post unmoderated comments and ratings of their books, suggests that it has real confidence in the quality of the book's material and readers' evaluations of it.
The aforesaid Web page also offers an online version of the index, but without any of the book's page numbers. At first glance, this might seem rather odd, but it does make some sense: Page numbers online would be of little use without the book itself, which of course already contains the index. Perhaps the index keys are offered to supplement the table of contents in helping the prospective customer learn what topics are covered in the book. In any case, this is the first time that I have seen a book's index online, and it will likely not be the last, if other publishers see the value in following suit.
In the preface, Shirley Kaiser explains that the book is intended to be "...a single source of solid information on best practices for everything from planning, designing, developing, and testing, to launching a web site and maintaining it in the long term. By compiling all this information into checklists, we've turned a vast wealth of detail into convenient, easy-to-scan, simple-to-use chunks organized by topic." A technical reader quickly scanning the book, would likely conclude that the author's goal has been achieved, because the book's 101 checklists comprise over 500 checkpoints, and almost all of them are expanded with at least a paragraph of more detailed explanation; many have accompanying code or images to illustrate the checkpoint.
The book's 331 pages of material are organized into 16 chapters, followed by an appendix that focuses on e-commerce advice. The topics covered in the chapters are: how to get started on a Web development project; planning the Web site with a client; assembling the site's content; managing that content; site usability; color schemes and functionality; information architecture; designing the site's navigation; W3C standards and recommendations; site accessibility; optimization of site performance; search engine optimization; design principles; site testing, including accessibility and usability; launch preparation and execution; post-launch follow-up and maintenance.
In terms of the specificity and usefulness of the checkpoints, they are not all consistently stellar, which arguably would have been an impossible expectation anyway. They range from the obvious (e.g., "Use consistent markup") to the not-so-obvious but equally valid (e.g., "Perform content audits"). Some of the checkpoints may on the surface appear mundane, but they could be a lifesaver further down the road, should a project turn sour (e.g., "Archive a copy of the handover package"). Some of them may seem painfully obvious to any decent developer (e.g., "Check all hyperlinks" and "Test all scripting functions"), but even the majority of those are violated on a daily basis, even by major Web sites, which have no excuse for such sloppiness.
The primary value of this book is how it neatly consolidates a considerable amount of worthy advice culled from the author's research and decade in the trenches of the Internet. The book probably will not replace all of the best practices that any top-notch developer will have assembled over the years — especially as none of it addresses advanced topics — but it could easily serve as a solid foundation upon which to add any supplemental recommendations that the book does not cover. Moreover, the book's material is presented in a fairly concise and quite readable format, making use of what appears to be a font slightly larger than is found in the typical computer programming book.
My only complaint with this title is the way that SitePoint continues to include a growing number of advertising pages, at the end of the book, with the bulk of each page black (sometimes even a bit smeared), and containing absolutely no details about the books being advertised. When SitePoint first began publishing books, if memory serves, they would only include one or two such over-the-top pages — possibly because they had so few titles to advertise at the inception. But now they are truly overdoing it. In Deliver First Class Web Sites: 101 Essential Checklists, no fewer than a dozen pages are wasted on this unwanted advertising. It would have been far more effective and efficient to simply list the 11 books' titles with a brief summary of each. Whoever decided to waste all that paper and ink, clearly did not read and understand some of the most basic checkpoints presented earlier in the book concerning type size and page content.
But overall, Deliver First Class Web Sites: 101 Essential Checklists is a much-needed book that brings together a wide range of valuable Web development best practices.

CSS: The Missing Manual
Michael J. Ross writes "Ever since Cascading Style Sheets (CSS) first appeared on the Web scene in the late 1990s, a plethora of books have been written and published that purport to explain how CSS works, and how to make it work for you. So why would any publisher decide that what the technical world needs is yet another CSS book? Perhaps because they have taken a close look at the bulk of those available titles, and found them to be wanting — filled with overly theoretical explanations and sample code that is far too focused on some pet domain of the author. Such books may be adequate for the veteran Web developer, who has the time and inclination to separate the wheat from the chaff. But developers new to CSS need much more approachable material, with clear examples. Perhaps that is the thinking behind CSS: The Missing Manual." Read the rest of Michael's review. CSS: The Missing Manual author David Sawyer McFarland pages 494 publisher O'Reilly Media rating 7 reviewer Michael J. Ross ISBN 0596526873 summary An accessible guide to using CSS with HTML.
Written by David Sawyer McFarland, CSS: The Missing Manual is published by O'Reilly Media, as part of their Pogue Press series, under the ISBN 0596526873. It first came out in August of 2006. The publisher maintains a Web page for the book, where visitors can find a link to register their copy of the book (does anyone do that?), a page for submitting errata (none yet, as of this writing), a form for posting a review on the O'Reilly site (again, be the first!), and a sample chapter (Chapter 1: Rethinking HTML for CSS) as a PDF file. There are also links for purchasing the book in the U.S. or the UK, and for reading the online version, as a part of O'Reilly's Safari service.
The book's 494 pages are organized into 14 chapters and three appendices, grouped into five parts. In addition, there is an index, as well as a terse but meaty introduction, which even includes a summary of HTML. The humor for which the Missing Manual books are known, begins early, in introduction, though in this case probably not intentionally: Page 9 claims that the book "is divided into four parts," and then lists the five parts. Before commenting upon those five-ish four parts, it should be noted that the table of contents runs seven pages, listing the book's parts, chapters, sections, and subsections. Future editions of the book would benefit from an overview table of contents, similar to those used in an increasing number of technical books, to good effect.
The 14 chapters cover most if not all of the essentials: writing HTML for CSS; creating styles and style sheets; determining what to style; using inheritance; using cascading; formatting text; setting margins, padding, and borders; styling graphics; styling links and navigation bars; styling tables and forms; creating float-based layouts; positioning page elements; creating print stylesheets; and writing maintainable CSS code. The three appendices include a CSS property reference, a discussion of CSS use in Dreamweaver version 8, and a listing of CSS resources to supplement the book.
On the positive side of the ledger, the author does a commendable job of clearly explaining all of the essential topics that the typical developer would need to understand in order to begin developing a robust Web site based on HTML and CSS, or reworking an existing site that is in desperate need of an overhaul. The clear explanations and bite-sized examples demonstrate that David Sawyer McFarland is not only an experienced Web developer, but likely has spent considerable time explaining to others how to do the same — as a writer, trainer, and instructor. This book is not his first, for he has previously written Dreamweaver: The Missing Manual.
One valuable aspect of the book under review, is that McFarland discusses how to overcome the most commonly encountered browser problems, in which Web pages employing CSS are not being formatted as one would expect and as specified in the CSS standards, by misbehaving browsers (that means you, "Internet Exploder"). Moreover, the book is also one of the first to document the significantly enhanced, long overdue, and welcomed CSS support in version 7 of the most commonly used Web browser (yes, we're still looking at you, "Browser by Bill").
The book is one in a series of many so-called Missing Manuals, whose tagline is "The books that should have been in the box," and whose Web site characterizes them as "Warm, witty, and jargon-free, [with] enough clarity for the novice, and enough depth and detail for the power user." In many respects, McFarland's latest contribution matches that description. In addition to the straightforward and yet comprehensive discussions of each topic, the author imbues his writing with a bit of humor, without overdoing it, or trying too hard, as is sometimes seen in other books covering subjects that admittedly can be quite dry.
On the negative side of the ledger, someone — or, more likely, some committee — somewhere along the decision chain, stipulated that almost every page of the book should be formatted so that the outside 1.5 inches, which is the easiest for a reader to see, should be consumed by a mostly empty and useless gutter, the bulk of which is filled with a light gray bar. This pushes the text, which slightly more than 4.5 inches wide, further in, toward the book's binding, and thus more difficult to read. This is true even though O'Reilly has wisely chosen to use RepKover, a flexible lay-flat binding. This exasperating style of layout is not characteristic of O'Reilly's books, which are generally much easier to read, with more sensible margins and often larger font.
One of the first principles taught to those learning Web design, is to avoid using white text on a black background. Such Web pages usually try to appear cool and edgy, but instead often comes off as immature in the eyes of an Internet veteran, and sinister to the Internet newbie. It doesn't work on Web sites, and it doesn't work in Web books. Sadly, O'Reilly chose to use white-on-dark-gray for many of the book's sidebars, making them difficult to read, especially as the sidebar text font size appears to be a bit smaller than that of the regular text.
In a nutshell, the content of this book is excellent, while the presentation of that content leaves much to be desired — ironic for a book focusing on CSS, whose primary purpose is to modularize and simplify presentation, neatly separating it from content. Ranking the content and presentation on a scale of 1 to 10, I would give them 9 and 5, respectively. Yet on balance, just as is true for most Web pages, the content is more important than its layout and other aesthetic considerations. CSS: The Missing Manual is a well-written, lighthearted, up-to-date, and easily accessible guide to modern CSS and how to use it in the real world.

Beginning Google Maps Applications with PHP and Ajax
Michael J. Ross writes "Just as PHP and other Web scripting languages have made it possible to create dynamic Web pages, online mapping services are making it possible to create dynamic maps that can be customized by a Web site owner, or made customizable by a site visitor. In the case of Google Maps, this is done using the built-in application programming interface (API), which is described in a new book, Beginning Google Maps Applications with PHP and Ajax: From Novice to Professional." Read on for the rest of Michael's review. Beginning Google Maps Applications with PHP and Ajax author Michael Purvis, Jeffrey Sambells, and Cameron Turner pages 384 publisher Apress rating 8 reviewer Michael J. Ross ISBN 1590597079 summary How to use the Google Maps API to make dynamic online maps.
But first, a brief background: During the mid-1990s, the only generally available mapping applications were desktop programs with location data limited to major cities within the United States. Yet less than one decade later, those programs were obsolete, replaced by Web-based mapping services such as MapBlast, MapQuest, and Yahoo Maps. In early 2005, Google raised the bar, with its own Web-based mapping service that was far more attractive than the others. For countless Internet users, it was their first glimpse of the power of AJAX, a new combination of technologies that allows Web pages to be refreshed asynchronously, providing a faster user interface. But Google Maps later packed another feature, an API that allows Web developers to leverage the service's capabilities in previously unimagined ways.
The authors of Beginning Google Maps Applications with PHP and Ajax — Michael Purvis, Jeffrey Sambells, and Cameron Turner — are based in Waterloo, Ontario, Canada. The book was published in August of 2006, by Apress, under the ISBN of 1590597079. The publisher maintains a Web page devoted to the title, where visitors can find an online table of contents, a sample chapter (Chapter 3, "Interacting with the User and the Server") as a PDF file, and a link for submitting errata (none of which, as of this writing, appear to have been reported — assuming there are any). In addition, the authors have a Web site for the book, where they offer a sample chapter (Chapter 4, "Geocoding Addresses") in PDF format, links to raw data sources, and brief entries describing a variety of related topics, including geocoding services, Google Maps Mobile (GMM), Keyhole Markup Language (KML), and building your own geocoding using Perl.
The book's material is organized into 11 chapters, grouped into three parts. The fourth and final part contains the appendices. The three primary parts can roughly be thought of as presenting the beginning, intermediate, and advanced information. Part 1, "Your First Google Maps," whets the reader's appetite by showing how to easily create some simple maps (discussed below). In addition, it contains a chapter explaining how a Google Maps mashup interacts with the user as well as the server. The final chapter in this part discusses geocoding addresses. Part 2, "Beyond the Basics," explains how to work with third-party data, how to enhance the user interface, how to optimize and scale for large data sets, and finally what possible future directions Google may take with this API. Part 3, "Advanced Map Features and Methods," presents exactly that, covering such topics as creating custom controls and info windows, adding geometric shapes to maps, and getting the most out of geocoding, including how to work with postal codes.
The authors begin Part 1 ("Your First Google Maps") by introducing Google Maps with the two most simple examples possible: Keyhole Markup Language (KML) is an XML-like formatting language that allows one to specify the names, coordinates, and descriptions of one or more locations ("placemarks") in a single file. For anyone who wishes to avoid writing the code themselves, Wayfaring is a Web site that allows one to create and share custom Google Maps by point and click. Even though the introduction to KML is properly brief, instead of only stating that the sample coordinates were discovered manually, the authors should mention at least one simple way to find those coordinates (such as the "Link to this page" link in Satellite view in Google Maps). Nonetheless, it was wise of the authors to use simple examples to get the reader's feet wet as quickly as possible — especially for prospective readers who might skim through the rest of the book and become intimidated by the technical diagrams, JavaScript and PHP code, MySQL queries, XML markup, and mathematical formulas.
There is much to like about this book. The explanations are straightforward, the code is readable, the examples are relevant, and the writing style is approachable. The illustrations, all of which are in black and white, are well-chosen, and not overwhelming in number. In addition to showing the expected results of the sample code, they also provide enough visual incentive to encourage the reader to give the sample code a try, and perhaps develop it further into their own mapping applications.
The book is not too lengthy, clocking in at 384 pages according to the publisher (though, oddly, Amazon.com reports only 350 pages, even though the last page of the appendix reads "358"). The authors resisted the increasingly common temptation to pad the book with superfluous appendices. Instead there are only two. The first explains how and where to find location data, such as addresses and latitude/longitude points. The second appendix presents the details of all of the classes, methods, properties, constants and events defined within the Google Maps API. For some reason the authors mention "objects" instead of properties and events, but I was unable to find any pre-instantiated objects mentioned in that appendix., and I am not sure such are even possible in the API.
Fortunately, the weakest section of the book, its foreword, has the least impact upon the value of the book. It fails to perform the most basic functions of a foreword, such as explaining to prospective readers why they should become actual readers, as well as what the book covers, and how the authors are qualified to provide that coverage. Instead, its author mostly discusses his personal Google Maps Mania site, and even wedges in mention of his appearance on an NPR radio show, which has little to do with the book. He also lists his first five posts to his Mania site, the first of which contains a misspelling, which should have been caught by the book's editors, or at least indicated with a "[sic]." The best part of the foreword is the first few paragraphs, which provide a brief history of Google Maps and the hacking thereof.
Like most if not all of its titles, Apress helpfully starts this book with two versions of the table of contents — the first one serving as a high-level overview, and the second providing far more detail, listing not only sections but subsections. This is a nice touch, and should be employed by all technical publishers. On the other hand, this book does not have a lay-flat binding, which is a shame, as it makes it far more difficult to read the book with both hands free for keyboarding. With the introduction of lay-flat bindings years ago, it is inconceivable to me why it has not been universally adopted, particularly by technical publishers.
Overall, Beginning Google Maps Applications with PHP and Ajax is an excellent introduction to extending the power of Google Maps on the Web, and provides enough detail to both help and entice readers to build their own Google Maps mashups.

Yet less than one decade later, those programs were obsolete, replaced by Web-based mapping services such as MapBlast, MapQuest, and Yahoo Maps. In early 2005, Google raised the bar, with its own Web-based mapping service that was far more attractive than the others. For countless Internet users, it was their first glimpse of the power of AJAX, a new combination of technologies that allows Web pages to be refreshed asynchronously, providing a faster user interface. But Google Maps later packed another feature, an API that allows Web developers to leverage the service's capabilities in previously unimagined ways.
The authors of Beginning Google Maps Applications with PHP and Ajax — Michael Purvis, Jeffrey Sambells, and Cameron Turner — are based in Waterloo, Ontario, Canada. The book was published in August of 2006, by Apress, under the ISBN of 1590597079. The publisher maintains a Web page devoted to the title, where visitors can find an online table of contents, a sample chapter (Chapter 3, "Interacting with the User and the Server") as a PDF file, and a link for submitting errata (none of which, as of this writing, appear to have been reported — assuming there are any). In addition, the authors have a Web site for the book, where they offer a sample chapter (Chapter 4, "Geocoding Addresses") in PDF format, links to raw data sources, and brief entries describing a variety of related topics, including geocoding services, Google Maps Mobile (GMM), Keyhole Markup Language (KML), and building your own geocoding using Perl.
The book's material is organized into 11 chapters, grouped into three parts. The fourth and final part contains the appendices. The three primary parts can roughly be thought of as presenting the beginning, intermediate, and advanced information. Part 1, "Your First Google Maps," whets the reader's appetite by showing how to easily create some simple maps (discussed below). In addition, it contains a chapter explaining how a Google Maps mashup interacts with the user as well as the server. The final chapter in this part discusses geocoding addresses. Part 2, "Beyond the Basics," explains how to work with third-party data, how to enhance the user interface, how to optimize and scale for large data sets, and finally what possible future directions Google may take with this API. Part 3, "Advanced Map Features and Methods," presents exactly that, covering such topics as creating custom controls and info windows, adding geometric shapes to maps, and getting the most out of geocoding, including how to work with postal codes.
The authors begin Part 1 ("Your First Google Maps") by introducing Google Maps with the two most simple examples possible: Keyhole Markup Language (KML) is an XML-like formatting language that allows one to specify the names, coordinates, and descriptions of one or more locations ("placemarks") in a single file. For anyone who wishes to avoid writing the code themselves, Wayfaring is a Web site that allows one to create and share custom Google Maps by point and click. Even though the introduction to KML is properly brief, instead of only stating that the sample coordinates were discovered manually, the authors should mention at least one simple way to find those coordinates (such as the "Link to this page" link in Satellite view in Google Maps). Nonetheless, it was wise of the authors to use simple examples to get the reader's feet wet as quickly as possible — especially for prospective readers who might skim through the rest of the book and become intimidated by the technical diagrams, JavaScript and PHP code, MySQL queries, XML markup, and mathematical formulas.
There is much to like about this book. The explanations are straightforward, the code is readable, the examples are relevant, and the writing style is approachable. The illustrations, all of which are in black and white, are well-chosen, and not overwhelming in number. In addition to showing the expected results of the sample code, they also provide enough visual incentive to encourage the reader to give the sample code a try, and perhaps develop it further into their own mapping applications.
The book is not too lengthy, clocking in at 384 pages according to the publisher (though, oddly, Amazon.com reports only 350 pages, even though the last page of the appendix reads "358"). The authors resisted the increasingly common temptation to pad the book with superfluous appendices. Instead there are only two. The first explains how and where to find location data, such as addresses and latitude/longitude points. The second appendix presents the details of all of the classes, methods, properties, constants and events defined within the Google Maps API. For some reason the authors mention "objects" instead of properties and events, but I was unable to find any pre-instantiated objects mentioned in that appendix., and I am not sure such are even possible in the API.
Fortunately, the weakest section of the book, its foreword, has the least impact upon the value of the book. It fails to perform the most basic functions of a foreword, such as explaining to prospective readers why they should become actual readers, as well as what the book covers, and how the authors are qualified to provide that coverage. Instead, its author mostly discusses his personal Google Maps Mania site, and even wedges in mention of his appearance on an NPR radio show, which has little to do with the book. He also lists his first five posts to his Mania site, the first of which contains a misspelling, which should have been caught by the book's editors, or at least indicated with a "[sic]." The best part of the foreword is the first few paragraphs, which provide a brief history of Google Maps and the hacking thereof.
Like most if not all of its titles, Apress helpfully starts this book with two versions of the table of contents — the first one serving as a high-level overview, and the second providing far more detail, listing not only sections but subsections. This is a nice touch, and should be employed by all technical publishers. On the other hand, this book does not have a lay-flat binding, which is a shame, as it makes it far more difficult to read the book with both hands free for keyboarding. With the introduction of lay-flat bindings years ago, it is inconceivable to me why it has not been universally adopted, particularly by technical publishers.
Overall, Beginning Google Maps Applications with PHP and Ajax is an excellent introduction to extending the power of Google Maps on the Web, and provides enough detail to both help and entice readers to build their own Google Maps mashups.

Pro PHP Security
Michael J. Ross writes "The global accessibility of Web sites is a double-edged sword: At the same time that your online e-commerce site is open for business to anyone with an Internet connection, it is also open to malicious attack. Web sites based upon the popular language PHP, are no exception. Thus, it is both astonishing and worrisome that there are currently so few books devoted to PHP security — particularly ones that go beyond the handful of typical security countermeasures discussed in articles. Fortunately, Pro PHP Security, written by Chris Snyder and Michael Southwell, is intended to fill this critical need." Read the rest of Michael's review. Pro PHP Security author Chris Snyder and Michael Southwell pages 528 publisher Apress rating 9 reviewer Michael J. Ross ISBN 1590595084 summary A comprehensive guide to developing secure PHP-based Web sites.
Pro PHP Security spans 528 pages, consisting of 24 chapters organized into four major parts. The first part, comprising only one chapter, explains the nature and significance of computer security, and reasons as to why absolute security is an unattainable goal. Nonetheless, it is worthwhile to take all appropriate and reasonable security measures, and the authors provide a brief overview of the different types of attacks to which Web applications are vulnerable.
On their Web site, Apress has a page devoted to the book, where they offer the book's source code (in a Zip archive file), the table of contents, corrections to the book (i.e., errata), and a sample chapter (Chapter 12 - Preventing SQL Injection) in PDF format. In addition, there is a link for any reader who would like to purchase this title as an e-book.
One of the most laudable aspects of Pro PHP Security, is that the authors — both experienced software and Web site developers — go far beyond the standard PHP security advice of validating and escaping user input, etc. Those topics are covered in depth, but they are provided in the context of thorough discussions as to how to set up a secure environment in which to use those techniques. In addition, the authors present best practices that have evolved over time, as Web masters and system administrators have learned — often the hard way — the general types of attacks to which their Web sites and computer networks have been subjected.
In fact, Snyder and Southwell hold off on presenting the aforesaid specific PHP security techniques, until the third part of the book. Prior to that, they explain the characteristics of a secure online computing environment, such as using encryption, securing network connections via SSL and SSH, controlling access via authentication and permissions, and other important topics. Their coverage of the subject matter is complete, without being overwhelming. For instance, the material on encryption is helpfully divided into two separate chapters — devoted to theory and practice, respectively. Consequently, a PHP application developer or system administrator can immediately dive into the authors' recommended practices for encoding sensitive data, without getting bogged down in the theoretical underpinnings, if the reader is in a hurry to implement encryption on their own systems, or simply has no interest in the theory behind the methods.
As noted earlier, Part 3 of this monograph explains all of the well-known techniques that crackers use for attacking PHP-based Web sites, as well as the countermeasures that should be adopted by the developer or maintainer of the site. First up is validation of user input, which — though being essential to basic security — is still neglected on far too many Web sites. The attention to detail seen in this discussion is also reflected in the subsequent chapters, which cover SQL injection, cross-site scripting, remote execution, temporary files, and session hijacking. For each topic, the authors explain how the typical attack is attempted, and what needs to be done to prevent such attacks.
The fourth and last major part of the book covers vitally important topics that are usually glossed over in most PHP security books, or neglected altogether. Snyder and Southwell explain methods of limiting access to your Web site to humans (thus minimizing attacks that employ scripts), verifying the identities of those users, authorizing what those users can do on your system, and tracking their actions once they have logged in. The authors also explain how to reduce the chances of data loss, and how to execute system commands and make remote procedure calls without exposing your site to vulnerabilities. The last chapter covers the benefits to be gained from opening up your site and its source code to a review by your technical peers.
This book has much to recommend it: The discussions of security issues are more complete and thorough than in any other book that I have seen. The information chosen by the authors is detailed enough to be understandable and usable, but not so excessive as to prove daunting or discouraging to the reader who needs answers to their security questions, and does not have the time or inclination to slog through academic or pointless discussion. The information is well-organized, and presented in context, so the reader is not simply given a laundry list of security techniques, but instead better understands the rationale behind them. Lastly, because no technical topic can be covered in full in a single book, the authors provide a generous number of references to outside resources.
The content of this book appears to have only one noticeable weakness, and that is the poor quality of the comments in the sample source code. Not only are they few in number and lacking in detail, but they are written in all lowercase letters, with little to no punctuation. This coding style results in the comments visually blending in with the code itself, and makes reading both to be more difficult than is justifiable.
The physical book itself also has only one weakness, and that may only apply to a portion of the copies produced and distributed by the publisher. Specifically, the bottom and side edges of the book are cut cleanly, while the top edge is quite rough. As I was unable to find any mention within the book as to a possible reason or advantage for having the rough edging on top of the pages, I can only conclude that it was not intended on the part of Apress, and represents an error in production. I hope that the copy that I received — kindly given to me by the publisher — is not representative of all the copies produced and sold.
In spite of these minor complaints, I was quite pleased with this book. Pro PHP Security is arguably the most comprehensive PHP security book available, and is highly recommended to any developer or administrator of a PHP-based Web site.
