Object-oriented languages
define objects (types of things) that know how to perform methods (specific actions).
Functional languages treat programming problems like mathematical relationships.
Ruby is flexible, meaning that you can program in any of these styles however, it is
primarily object oriented, with some strong functional influence. This book focuses
slightly more on the functional aspects of Ruby than some other books.

A Module-based Wireless Node (MW-Node) is a Node with wireless and mobile capabilities added by means of modules. It is not a new node object derived from Node. Rather it is a new layout of mostly existing components. Rationale for this new design has been presented in [1]. The MW-Node provides a flexible support for wireless and mobile networking and in particular:
support for multiple interfaces/multiple channels, and
a common basis for the implementation of wireless routing protocols.
jsp和xml。XML and JSP are two important tools available in producing a web application. This chapter examines the
potential of mixing these two technologies in order to enhance the capabilities of JSP. While this chapter will
cover many things about XML, this chapter will not attempt to teach XML. Instead it focuses on how JSP and
XML can be used together as a highly flexible and powerful tool. In general the usage of XML in these
examples will be kept simple and should cause no problems for users who are starting XML.
非線性有限元程序，NONSAP is a general finite element program for the nonlinear static and dynamic analysis of complex structures. The program is very flexible and was designed to be extended and modified by the user. In particular the program can easily be modified to use a different formulation of the equations of motions, different time integration operators and other additional options.
Imperfect C++ Practical Solutions for Real-Life Programming
C++, although a marvelous language, isn t perfect. Matthew Wilson has been working with it for over a decade, and during that time he has found inherent limitations that require skillful workarounds. In this book, he doesn t just tell you what s wrong with C++, but offers practical techniques and tools for writing code that s more robust, flexible, efficient, and maintainable. He shows you how to tame C++ s complexity, cut through its vast array of paradigms, take back control over your code--and get far better results.
fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas.
fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon.
fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.
Perl and XML
XML is a text-based markup language that has taken the programming world by storm. More
powerful than HTML yet less demanding than SGML, XML has proven itself to be flexible and
resilient. XML is the perfect tool for formatting documents with even the smallest bit of
complexity, from Web pages to legal contracts to books. However, XML has also proven itself to
be indispensable for organizing and conveying other sorts of data as well, thus its central role
in web services like SOAP and XML-RPC.
As the Perl programming language was tailor-
