Written by one of the designers of the PowerShell environment, the author knows all the ins and outs, back-alleys, hidden rooms, and secret handshakes the language offers - and isn't afraid to grab you by the hand and drag you along (like it or not!) for the tour of your life. ¥n<br />¥n<br />Therein, however, is the reason I can't recommend this as your first PowerShell book. The book is very logically planned out, the information very well presented in relatively easy to understand language, there is an abundance of script snippets to demonstrate what is being talked about, and the writing style itself is entertaining to read. But the author knows too much on the subject, and like any proud parent, often ¥"too much information¥" is given, delving too deep into the gears and cogs of PowerShell and the underlying .NET framework for the (often basic) building block component, which might overwhelm the new PowerShell user, especially if the user does not have programming, let alone scripting, experience. ¥n<br />¥n<br />So although I say don't make this your first purchase, make it your second - and probably your last. Start with an ¥"Introduction¥" style book (like [[ASIN:1598633546 Microsoft Windows Powershell Programming for the Absolute Beginner]]) to get used to the complex environment (even if you've only had VBS/JS experience), get comfortable with the basics of the shell, then move up to this title.

Plus, who ever thought that the history of a program could be as interesting as this one is. After all, the book begins by asking ¥"why another shell language?¥" By the time you are into a few chapters you realize the question should have been ¥"what took you so long?¥" ¥n<br />¥n<br />The book is peppered with valuable code examples that show off everything from the basics to the most advanced concepts, and the examples are built incrementally so you can see how and why every character in a command line works. Since PowerShell is object oriented, you easily learn why this is important, and how to extract the power of an OO shell.¥n<br />¥n<br />I've already put PowerShell to work at the office using it for WMI, Active Directory, and file management tasks and have incorporated it into my AutoIT scripts as well.

But whether you're a UNIX user or not, you can benefit from a better understanding of regular expressions since they work with applications ranging from validating data-entry fields to manipulating information in multimegabyte text files. <b>Mastering Regular Expressions</b> quickly covers the basics of regular-expression syntax, then delves into the mechanics of expression-processing, common pitfalls, performance issues, and implementation-specific differences. Written in an engaging style and sprinkled with solutions to complex real-world problems, <b>Mastering Regular Expressions</b> offers a wealth information that you can put to immediate use. "

Then, the author takes a look at text processing with regular expressions. Next, the author provides an overview of features and utilities, plus a bit of history. He also explains the details of how regular expressions work. The author continues by working through regular expressions examples. Then, he discusses efficiency in detail. Next, the author covers Perl regular expressions in detail. He then looks at Sun's java.util.regex package. The author continues by looking at .NET's language-neutral regular-expression package. Finally, the author looks at PHP's preg suite of regex functions. ¥n<br />¥n<br />This most excellent book should expand your understanding, even if you consider yourself an accomplished regular-expression expert.

Regular expressions are not easy and the quirks of the different tools (including their exact version and for what operating system) make writing them to an irritating black art. A black art to almost anybody. MRE sorts everything out in a comprehensible fashion. The price the reader has to pay: a very dense book, a need to follow the details until your head starts swimming and a lot of strain on the memory about what works, how and where.¥n<br />¥n<br />¥n<br />MRE is somewhat easier to comprehend for a reader with a strong Pearl background. Also a good prior understanding to regular expressions is a true asset here. If you have neither, you do not need to despair. Jeffrey Friedl explains everything thoroughly from the ground up. ¥n<br />¥n<br />¥n<br />The writing style is very pedagogical. Important things get repeated quite often. Still this book is very dense. The flow is dry: no rhythm, special sense of humor or wit sweetens your wading through the material.

The O'Reilly Cookbook series aims to fill the blank space between talkative introductory guides and heavy reference tomes for programming languages. Edited as a set of ¥"recipes¥" - practical programming problems, divided into topics, the Cookbooks are a great way to quickly find solutions for common problems, and can also serve as a good intermediate / advanced tutorial to the language for those of us who like learning by example.¥n<br />¥n<br />The Ruby Cookbook can proudly hold a very respected spot in the Cookbook series, being very comprehensive and well written. The authors clearly strove to cover a lot of topics and provide copious examples, not sparing 800+ pages for the task.¥n<br />¥n<br />The first ten chapters of the book deal with general Ruby programming topics such as strings, code blocks, metaprogramming, etc. These chapters can serve as a good tutorial in advanced Ruby, presenting interesting examples and discussing different approaches to solve problems.¥n<br />¥n<br />The next six chapters are devoted to more specific topics: XML/HTML, Graphics, Databases, Internet, Rails and Web Services. These can be either very important or barely relevant, depending on what you do with Ruby. I skimmed through a good chunk of these chapters, since I don't use Ruby for web programming.¥n<br />¥n<br />Chapter 17: Testing, Debugging, Optimizing and Documenting is the one I liked most in the book. The authors skillfully present how to use the special strengths of Ruby to make the work of a programmer easier. The recipes in this chapter are good advocates for using Ruby over other languages.¥n<br />¥n<br />Next come few more chapters about GUIs, Multithreading, Rake and other miscellanea, providing an overview of the more advanced features of Ruby.¥n<br />¥n<br />Overall, the scope of this book is just huge - it's a mine of information, and a very good tool for any Ruby programmer. Overlooking a few minor typos and errors, the book is quite well written and the authors know how to get their message through with detailed examples and numerous code samples.", @summary="Another good Cookbook from O'Reilly - very useful for Ruby coding">]

reviews = [#<Amazon::Product::Review:0x6b01d0 @rating=5, @comment="Javascript has exploded onto the web development scene in the last few years, and powers much of the web 2.0 and Ajax revolution. Every web developer now needs to know how to do common Ajax tasks. Thankfully, Prototype and Scriptaculous In Action makes it both easy and enjoyable.¥n<br />¥n<br />This is a comprehensive book. The size (510 pages) was initially intimidating, but Prototype and Scriptaculous In Action is exceedingly well written and a genuine pleasure to read. The thorough and thoughtful organization of the book provides some real structure to the discussion, making complex subjects easily digestible. This is the defacto bible of Prototype and Scriptaculous, and these days I turn to this book more than anything else on my shelf. ¥n<br />¥n<br />The book is divided up into four multi-chapter parts, any of which could stand on it's own as a definitive guide. The chapters are full of useful examples, and there's strong emphasis given to migrating existing sites to Prototype and Scriptaculous, which is a major plus. You could turn to any section of the book and immediately see how to inject some new behavior into your existing application, but if you take the time to read from cover-to-cover you'll be rewarded with some deep understanding of both the libraries and Javascript itself.¥n<br />¥n<br />I'll summarize the four parts of the book:¥n<br />¥n<br />Part 1, Getting Started, introduces the Prototype and Scriptaculous libraries, focusing heavily on Prototype and Ajax. There's a lot of information on re-designing an existing site for Ajax. Two full chapters are devoted to Prototype's Ajax features. You can get up and running VERY quickly after glancing through these chapters. There's also a lot of depth, and consideration is given to the pervasive effects Ajax has on architectural issues and the new ways that an application will have to manage HTTP traffic.¥n<br />¥n<br />Part 2, Scriptaculous Quickly, covers effects, controls and drag-n-drop. This is hands-down the best Scriptaculous documentation currently available, anywhere. The core effects are explored and tweaked, and there's lot of very practical examples demonstrating some of the niftiest stuff, like running effects in parallel versus sequentially. And the drag-and-drop coverage is incredibly clear, making it easy, almost trivial, to implement. The Scriptaculous coverage is indispensable, and you'll return to it again and again if you implement Scriptaculous-enabled pages.¥n<br />¥n<br />Part 3, Prototype in Depth, explores Prototype's Javascript-oriented features. There's a fantastic chapter on functions contexts, and the discussion of closures is one of the best I've seen. There's a lot of information about Javascript fundamentals, and how Prototype can be used to implement inheritance, address arrays, and manipulate the DOM in the browser.¥n<br />¥n<br />And finally, Part 4 Advanced Topics, has two unrelated chapters. The first chapter overhauls an example app, giving it a Prototype and Scriptaculous makeover. The last chapter is about integration with Ruby on Rails. Prototype was initially written as the Ajax interface to Rails, so there's some strong integration.¥n<br />¥n<br />As a long-time enterprise web developer, dealing with Javascript has always been a chore. But now I actually (gasp) look forward to tasks that involve Javascript. I'm a convert, and I have Prototype and Scriptaculous in Action to thank. ", @summary="Top-notch tome">, #<Amazon::Product::Review:0x6b0158 @rating=4, @comment="I wrote a longer review that Amazon has apparently lost. Oh well. This is an excellent book, very well written. The authors are the rarest kind of technical author: they can actually construct prose that is pleasant to read, not deadly boring, but which works well as a reference book later. The book's organized thoughtfully--it's certainly much more than just an API reference. There's also quite a lot of general advanced Javascript information here, too.¥n<br />¥n<br />There's at least one other book on these libraries in production from Pragmatic Programmers. If you're considering that, I strongly suggest downloading the sample chapters of both books and comparing. The Crane book is much more appealing to me (not to mention it's available now, not in six months).", @summary="Excellent">, #<Amazon::Product::Review:0x6b011c @rating=3, @comment="This book lacked detailed coverage of the programming techniques and advanced topics of prototype and scriptaculous. The authors covered the basics by discussing only the API's of the libraries (more attention was given to scriptaculous API's, even though its usage is obvious and prototype API's are more extensive). With 500 pages and the libraries as the title, I expected details about the inner workings of the API's and discussions about its usages/ applications. Instead, 150 pages were devoted to verbose repetitive coverage of scriptaculous' API, which could easily have fitted into 50 pages at most. ALL of the info on scriptaculous could easily have been read online at its wiki site - the book provided no further insight (ch. 5 is especially useless)! Prototype's coverage was decent, but lacked details on several parts of its API. Although prototype and scriptaculous are tightly integrated with Rails, there was only 1 chapter devoted to its discussion, which served more like an overview than a usage guide. Based on content on the libraries alone, I would give this book 3 stars. However, if you're in need of an example application, then it may deserve 4 stars. This book provides a good example of applying prototype's ajax and scriptaculous web 2.0 techniques to a photo gallery website. It shows the advantages these libraries have over plain javascript and dhtml. The extra 100 pages wasted on scriptaculous would better serve Rails' RJS templates or a more complete/ thorough discussion of prototype. Of course it can be argued that the book is not titled, ¥"Prototype, Scriptaculous, and Rails in Action,¥" but it should be.", @summary="Basic libraries coverage with a good example application.">]

product_description = "Good programming--which is to say, programming that yields both efficient code and a profitable life for the programmer--depends on not reinventing the wheel. If someone else has solved the problem you're facing (and someone almost always has), you'd be foolish to waste your energy figuring out your own solution. <I>MySQL Cookbook</I> presents solutions to scores of problems related to the MySQL database server. Readers stand a good chance of finding a ready-made solution to problems such as querying databases, validating and formatting data, importing and exporting values, and using advanced features like session tracking and transactions. Paul DuBois has done a great job assembling efficient solutions to common database programming problems, and teaches his readers a lot about MySQL and its attendant APIs in the process.<p>DuBois organizes his cookbook's recipes into sections on the problem, the solution stated simply, and the solution implemented in code and discussed. The implementation and discussion sections are the most valuable, as they contain the command sequences, code listings, and design explanations that can be transferred to outside projects. The main gripe readers will have about <I>MySQL Cookbook</I> is that the author, in his effort to cover the range of MySQL-friendly programming languages, uses different languages in his solutions to various problems. You'll see a Perl solution to one programming challenge (Perl, in fact, is the most frequently used language, followed by PHP), a Python fix for the next, and a Java sample after that. Readers have to hope that they find a solution in the language they're working with, or that they're able to transliterate the one DuBois has provided. It's usually not a big problem. <I>--David Wall</I> <p> <B>Topics covered:</B> How to make MySQL databases do your bidding--in terms of queries, table manipulation, data formatting, transactions, and Web interfaces--through the database server's command line interfaces and (more importantly) through the MySQL APIs of Perl, PHP, Java, and Python. Particularly excellent coverage deals with formatting dates and times, management of null values, string manipulation, and import/export techniques."
