The Writers Perspective

PHP doesn’t spring to mind when thinking about processing XML data, but PHP is a better solution than you might think. Since PHP is used to develop websites, which use HTML a standard based on the principles of XML, PHP is a sensible choice. PHP also includes powerful tools for parsing and manipulating XML data. We can use this to our advantage to convert and manipulate XML information in our PHP based web applications. XML-RPC and SOAP also use XML, so the use of a web-based language for web-services is also another obvious choice.

All of these situations are covered in extensive detail by Thomas Myer in his new book, No Nonsense XML Web Development with PHP from publisher SitePoint, a long time source for articles and information on web applications and development.

The contents

No Nonsense XML Web Development with PHP covers a gamut of different topics, from an introduction on the basics of XML and its uses through to web services. Throughout, the straightforward and relaxed tone of the book help you to pick up the background behind what Thomas is teaching you, as well as the specifics of different aspects in the book.

We start off with a simple examination of XML and the role of DTDs in the consistency of the XML data. Thomas is right here to point out that DTDs are about consistency, rather than restriction, on the information we store in XML. He also covers the role that DTDs have in validating information, often simplifying the code required in our application to confirm the quality of the content.

Linux Made Easy by Rickford Grant is a companion to his original Linux for Non-geeks. Where the two differ is that this book is about how easy Linux can be for performing a myriad of tasks using a simple, skill-based approach. In this book, Rickford describes how to use Linux to do what you need to do: web browsing, sending email, basic document creation and using external peripherals like your printer, USB flash drive and scanner. In short, this book is about using Linux, from the perspective of ‘Your Average Joe’.

The book covers, and indeed includes, Xandros Open Circulation Edition, a Debian based distribution that just happens to include a number of key components for the target market, including OpenOffice, a key part of the toolkit required by many users to provide word processing and spreadsheet facilities.

The contents

In consideration of the target audience the book is a meaty, but not imposing, 450 pages making it look both substantial enough to keep potential readers interested and yet not so large as to make them think twice about buying a ‘professional’ book.

If you use a free software operating system or environment, chances are one of your key interfaces will be through some kind of shell. Most people assume the bulk of the power of shells comes from the commands available within them, but some shells are actually powerful in their own right. Many of the more recent releases being more like a command line programming environment than a command line interface. “From Bash to Z Shell” published by Apress, provides a guide to using various aspects of the shell. From the basic command line interaction through to the more complex processes of programming, it touches on file pattern matching and command line completion along the way.

The contents

Shells are complicated – how do you start describing working with a shell without first describing how the shell works, and don’t you show them how to use it by doing so? The book neatly covers this problem in the first chapter with what must be the best description of a shell and how the interaction works that I’ve ever read.

Linux in Windows World aims to solve the problems experienced by many system administrators when it comes to using Linux servers (and to a lesser extent clients) within an existing Windows environment. Overall the book is meaty and a quick flick through shows an amazing amount of information has been crammed between the covers. There are though some immediately obvious omissions, given the books title and description, but I’m hoping this won’t detract from the rest of the content.

The contents

The book starts off with a look at where Linux fits into a Windows network, covering its use both as a server and desktop platform. Roderick makes some salient points and arguments here, primarily for, rather than against, Linux but he’s not afraid to point out the limitations either. This first section leads on to a more in depth discussion of deploying a Linux system into your network, promoting Linux in a series of target areas – email serving, databases and so on – as well as some strategies for migrating existing Windows desktops to Linux.

Knoppix is not just another Linux distribution. Unlike many Linux alternatives, Knoppix doesn’t need to be installed; everything runs from a CD (called a ‘Live CD’ distribution). While Live CDs aren’t unique to Knoppix, it is the way the Knoppix CD is packaged that makes the difference. Knoppix includes intelligent hardware detection – it can automatically identify nearly everything on your machine and then make the bet of it – and the CD includes a wide selection of programs, from typical Linux applications through to repair utilities and tools.
