I’m finally finished with my review of the first book, Catalyst: Accelerating Perl Web Application Development. Note that while I was asked, I wasn’t paid for this review, this is my personal opinion.

Firstly, for anyone unfamiliar with Catalyst, Catalyst is a MVC (Model-View-Controller) framework using Perl, for anyone familiar with Ruby on Rails, Catalyst is extremely similar.

The book is written by Jonathan Rockway, who is one of the core team members of the Catalyst team, which gives the book a solid technical background. The book’s text is easy to read and understandable.

Catalyst starts by giving a brief introduction to the MVC methodology and instructions for downloading and installing the Catalyst run-time. One thing to note is that this book is not for readers new to Perl, the book assumes you have a solid knowledge of Perl intricacies and experience using CPAN, which is required to install the multitudes of modules required for Catalyst development. I found that a certain level of problem-solving was required, as not all CPAN modules installed cleanly. I had to force-install a few of the modules and manually resolve a number of dependencies in order to get all the required modules. This barrier to entry might discourage some beginners just starting out with Perl and Catalyst. Other than that, all the installation instructions were very clear.

Developers don’t learn very well with just theory, so Catalyst does a good job of providing a sample application to develop and extend throughout the book. The bulk of the development centers around creating an Address Book application, which is then extended to have features like authentication and AJAX later on during the book. Personally, I’m happy the same application is used, rather than switching applications every chapter. The book does change applications for a couple of chapters (which I find is good, to give a different app’s perspective), then returns to the first application afterwards.

The book discusses a lot of the cool features of Catalyst, such as FormBuilder, templates, REST APIs, Jemplates, AJAX and RSS feeds. The book describes ways to use these features to help speed up development and move away from repetitive code creation. In chapters 8 and 9, testing and deployment are discussed. Personally, I would have liked to see the testing and deployment chapters moved up and integrated into the earlier chapters to enforce a methodology that includes testings from the beginning of development, but I can understand moving it to the end to make entry into the framework a little easier.

One other thing to note, as with almost any programming book, syntax and spelling errors can be killer when attempting to replicate code written in a book, the Catalyst book has a list of errors pertaining to the code in the book, which caused me a great deal of frustration until I looked up the errata. I recommend that anyone use the code example either downloaded from the website or directly from the book take a look and make sure they get the correct syntax. The only other thing I would have liked to see was a chapter on security concerns of the Catalyst framework (being concerned about security myself), I was disappointed they didn’t show up in the book, perhaps in the next edition. I have noticed (from googling for errors I ran into), that Jonathan is very vocal on forums about helping people, so I have no doubt that the syntax errors will be corrected in a future edition :)

Alright, enough blathering from me, here’s the short and sweet summary: This book is great for Perl or Ruby programmers who are already familiar with MVC development and are interested in the Catalyst framework. The book is not exhaustive by any means, and is not overly long (I would say this is a good thing), it provides a very solid foundation to work with, and a developer should be able to develop his/her own app after reading it. If you’re a Ruby developer interested in a Perl alternative to Rails, or if you’re a Perl developer jealous of Rails, I encourage you to check it out.

P.S. I have also posted this review to Amazon here.

Hex and NSM-Console writeup in February ISSA Journal http://writequit.org/blog/2008/02/04/hex-and-nsm-console-writeup-in-february-issa-journal/ http://writequit.org/blog/2008/02/04/hex-and-nsm-console-writeup-in-february-issa-journal/#comments Mon, 04 Feb 2008 15:07:13 +0000 http://writequit.org/blog/?p=143 Russ, the author of holisticinfosec.org has kindly written up a review of the Hex NSM-liveCD in the February edition of his ‘toolsmith’ column for the ISSA journal. The column is a good 3-4 pages about Hex as well as some of the tools included on the distribution. There’s even a page dedicated to NSM-Console (Although the review is using the older 0.2 and 0.3 versions and there’s been lots of improvements in NSM-Console since). Thanks for the awesome review Russ!

Although it looks like the February version of the ISSA journal hasn’t been pushed out of the website just yet, you can check out Russ’ columns here, or download February’s column directly here.
