Product Description
In each column, Randal ... carefully discusses the problem, and then shows the Perl code needed to resolve it. Each column is written in a conversational style that is easy to read, yet doesn't talk down to you. Check out the table of contents and see why it made my mouth water. If you are a Perl fan, you will enjoy this. Highly recommended.

<p><i>Randal Schwartz's Perls of Wisdom</i> is a collection of more than 70 columns from popular and prolific Perl columnist Randal Schwartz. These insightful pieces cover everything from Perl basics to how to decompose XML using an HTML parser. Schwartz's unique writing style and (sometimes) truly twisted use of Perl makes for exciting reading for those who want to enhance their Perl skills.</p>

About the Author
Randal Schwartz is one of the bestselling authors of all time, having been fortunate enough to coauthor two of the seminal books on learning Perl. Perl is perhaps the seminal programming language of the Internet boom and one of the most popular programming languages for doing anything from system administration to parsing a CSV file. In addition to <i>Programming Perl</i> and <i>Learning Perl</i>, Randal just completed a new book for intermediate Perl developers, and has been the Perl columnist for <i>UNIX Review</i>, <i>Web Techniques</i>, <i>Sys Admin</i>, and <i>Linux Magazine</i>.

3.0 out of 5 stars A dated compendium of Randal's Perl columns, March 4, 2005

By	R. Lodato "grey geek" (Boston, MA) - See all my reviews (REAL NAME)

Anyone who has been working on the *nix platform has had a brush with Perl, the scripting language whose acronym (depending on who you ask) could mean Practical Extraction and Report Language, or Pathologically Eclectic Rubbish Lister. In either case, there is a distinct difference between learning to use Perl, and learning to use it well. In my opinion, the best way to learn any language well is to see how others have used it to solve problems. One of the foremost experts in the use of Perl, Randal L. Schwartz, has been writing columns since March of 1995 on the use of Perl in the real world, and has provided us with 6 books and over 200 columns with many examples on how Perl is used.
Perls of Wisdom is a collection of 65 selected columns from Linux Magazine, Unix Review, and the now defunct Web Techniques magazines, written between May 1995 and July 2004. In each column, Randal discusses some problem that he had to solve, or that someone else needed help in solving. He carefully discusses the problem, and then shows the Perl code needed to resolve it. Many of the columns are complete applications that can be run (with minor modifications) by the reader. (The listings are also available from the apress.com web site.) Each column has been reproduced as it was written in the original magazine, with "Randal's Note" prepended. Therein lies this book's best feature and greatest flaw.
In its entirety, Perls of Wisdom contains 65 columns, split roughly half-and-half between tutorials and fully commented programs. More than half of the columns show that Randal uses Perl for web processing more than for general scripting, data reduction and reporting. His tutorial articles are top-notch, but I have a quibble over his program articles, which are somewhat dated. There were a number of prefaced notes to the effect that today he'd do it differently with some new feature or CPAN module. I really wish he had actually updated the column to show the new coding techniques. The original code is interesting in the historical sense, but I wanted to see nuggets of Perl wisdom for me to use in my daily job. The writing style is fine; the bits of insight are useful, but many of the programs are too specific to problems you or I may never see, and were solved in code that's showing its age. I'm glad I got to read the book, but I think it only rates a 3 out of 5.

4.0 out of 5 stars useful setof essays, February 5, 2005

By	W Boudville (Terra, Sol 3) - See all my reviews (TOP 50 REVIEWER)    (REAL NAME)

Isn't it nice to have something on Perl that doesn't start at the beginning? Schwartz is one of the best known proponents of Perl and he offers expert advice in this book. It is a collation of what he regards as his best essays. These appeared over the last 10 years in columns he wrote for Web Techniques, Linux Magazine, Unix Review and Perl Journal.

For Perl programmers, it's useful to have these essays in easy reach, as opposed to thumbing through your back copies of those magazines.

The essays are grouped into broad categories. For those involved in web applications, you might turn to the chapters on CGI and on HTML and XML. Though I do wonder a little about the former choice. Nowadays, CGI tends to be deprecated, in favour of JSP or ASP approaches. Mainly because CGI coding turned out to be so dreadfully awkward. Granted, Perl helped mitigate some of this, but even so, the demand for Perl CGI scripts might have fallen since the 90s.

4.0 out of 5 stars Enjoyable, if dated, December 14, 2007

By	David Berube - See all my reviews (REAL NAME)

I really enjoyed this book - I haven't had to write Perl consistently in years, but programming, ultimately, is programming, and the book shows clear thinking the whole way through. Many of the problems tackled aren't big issues anymore, of course, but it's still a great read.
