Linux App Development for the Enterprise

The book is meant for both, absolute beginners as well as experts. The author first describes the basics of how a typical Linux system boots up and then moves on to clarify and explain a few basic concepts and techniques to Windows developers. From there we move on to how to get help from the system when we're stuck, shell scripting and finally into programming proper. 

This book uses Object Pascal (Delphi) to explain OOPS concepts. The book uses a dual language concept throughout, using Delphi to explain the basics and then showing you how to do the same with Java. 

As you progress through the book, the focus shifts from explaining small bits of code to advanced programming concepts such as learning desktop and client-server (distributed) development. This is one book that can be used by application developers whether they started out under Linux or Windows. Amazingly, almost all code given is platform independent, which means you can use it with Delphi and Java for Windows as well! Nice touch.
