Companion—a decade during which some people prophesied the demise of TEX

There's a lot to be said for going back to basics. Not only does this Bible give you a quick refresher on the structure of open-source Linux software, it also shows you how to bypass the hefty graphical user interface on Linux systems and start interacting the fast and efficient way?with command lines and automated scripts. You'll learn how to manage files on the filesystem, start and stop programs, use databases, even do Web programming?without a GUI?with this one-stop resource.

Understanding XML Structure
You will likely see additional tags at the start of XML documents that you should be aware of. The first is the XML declaration tag, and it usually looks something like this:
This may differ, depending on the source document, but the purpose of such a tag is usually the same. It tells parsers the version of the XML language specification and the type of encoding used when the file was written.

C # programmers at any level need to learn about LINQ (Language-Integrated Query),
Microsoft’s breakthrough technology for simplifying and unifying data access from any data
source. With LINQ you can write more elegant and flexible code, not just to access databases
and files but also to manipulate data structures and XML.
LINQ for Visual C# 2008 is a short guide to the major features of LINQ. It thoroughly covers
LINQ to Objects, LINQ to SQL, LINQ to DataSet, and LINQ to XML. For instance, you’ll
