Book excerpt: Implementing cryptography requires integers of significant magnitude to resist cryptanalytic attacks. Modern programming languages only provide support for integers which are relatively small and single precision. The purpose of this text is to instruct the reader regarding how to implement efficient multiple precision algorithms. Bignum math is the backbone of modern computer security algorithms. It is the ability to work with hundred-digit numbers efficiently using techniques that are both elegant and occasionally bizarre. This book introduces the reader to the concept of bignum algorithms and proceeds to build an entire library of functionality from the ground up. Through the use of theory, pseudo-code and actual fielded C source code the book explains each and every algorithm that goes into a modern bignum library. Excellent for the student as a learning tool and practitioner as a reference alike BigNum Math is for anyone with a background in computer science who has taken introductory level mathematic courses. The text is for students learning mathematics and cryptography as well as the practioner who needs a reference for any of the algorithms documented within. * Complete coverage of Karatsuba Multiplication, the Barrett Algorithm, Toom-Cook 3-Way Multiplication, and More * Tom St Denis is the developer of the industry standard cryptographic suite of tools called LibTom. * This book provides step-by-step exercises to enforce concepts

Book excerpt: In the days before personal computers, BASIC was the easy programming language to learn, and serious programmers learned FORTRAN or COBOL to do “real work.” Today, many people have discovered that Perl is both a great beginning programming language and one that enables them to write powerful programs with little effort. If you’re interested in discovering how to program (or how others program), Perl For Dummies, 4th Edition, is for you. If you already know something about programming (but not about Perl), this book is also for you. If you’re already an expert programmer, you’re still welcome to read this book; you can just skip the basic stuff (you never know what kind of new tips and tricks you’ll pick up). This reference guide shows you how to use Perl under many different operating systems, such as UNIX, many flavors of Windows (Windows 95/98, Windows NT, Windows 2000, Windows Me, and Windows XP), and Macintosh OS 9 and OS X; in fact, Perl runs on many more operating systems than these. Here's a sampling of what Perl For Dummies, 4th Edition, has to offer: Installing Perl on various platforms Nailing down the basics of building Perl programs Working with text and numbers Constructing lists and working with them Creating conditionals and loops Delving into more advanced features such as operators and functions Reading and writing files and directories Using subroutines for modularity Demystifying Web server programs Creating your own Internet clients The Perl programming language enables you to write fully working computer programs with just a few steps. It’s particularly good at common programming tasks, such as reading and writing text files, but it also excels at reducing the work that programmers have to do. Perl For Dummies, 4th Edition, shows you how to do all of that and how to modify programs to your heart’s content. After all, one of the common phrases in the world of Perl programmers is, “There's more than one way to do it.”

Download or read book Foundation Rails 2 written by Eldon Alameda and published by Apress. This book was released on 2008-11-23 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: You've heard about this amazing web framework called Ruby on Rails that's taken the world by storm, but thought it was way too complex for you? Think again. Foundation Rails 2 takes you through your first steps in Rails, explaining in plain English how to start building dynamic web applications. And there's never been a better time to jump in to the Rails world, as the release of Rails 2 was a major evolutionary leap forward from previous versions. Unlike other Rails books, this book doesn't throw you into the deep end right away in the hopes that you'll learn to swim. Instead, we'll start out with the basics and continually expand your knowledge until, by the end of the book, we're building a Rails application with dynamic features such as user registration, geocoding, filtering results with AJAX, RSS feeds, and an XML interface. Meanwhile, we'll talk about the important issues that other books often leave out such as testing your application's code, securing your application from hackers, optimizing your code for the best performance, and of course, deploying your application. This book takes a focused approach to guiding you through understanding how the pieces of Rails work individually and how they fit together. Instead of emphasizing boring theoretical discussions, Foundation Rails 2 lets you get your hands dirty with the framework and learn the hows and whys of Rails faster than ever. We start with a tour of what makes Rails special and why you need to learn it, move into a gentle introduction to the high points of programming in Ruby, and then take a tour of a sample Rails application. Next, we dig deeper into the core components of Rails before building a complete Rails application together. By the end of this book, not only will you know how to build Rails applications but you'll understand the reasons behind what you do.
