Ideal as an introduction for beginners and a quick reference for advanced programmers, Regular Expression Pocket Reference is a comprehensive guide to regular expression APIs for C, Perl, PHP, Java, .NET, Python, vi, and the POSIX regular expression libraries. This handy book offers programmers a complete overview of the syntax and semantics of regular expressions, which are at the heart of every text-processing application. When you've reached a sticking point and need to get to a solution quickly, the new Regular Expression Pocket Reference is the book you'll want to have.

Many programmers code by instinct, relying on convenient habits or a "style" they picked up early on. They aren't conscious of all the choices they make, like how they format their source, the names they use for variables, or the kinds of loops they use. They're focused entirely on problems they're solving, solutions they're creating, and algorithms they're implementing. So they write code in the way that seems natural, that happens intuitively, and that feels good.

But if you're serious about your profession, intuition isn't enough. Perl Best Practices author Damian Conway explains that rules, conventions, standards, and practices not only help programmers communicate and coordinate with one another, they also provide a reliable framework for thinking about problems, and a common language for expressing solutions. This is especially critical in Perl, because the language is designed to offer many ways to accomplish the same task, and consequently it supports many incompatible dialects.

This book provides a basic, in-depth look at techniques for the design and analysis of parallel algorithms and for programming them on commercially available parallel platforms. Principles of parallel algorithms design and different parallel programming models are both discussed, with extensive coverage of MPI, POSIX threads, and Open MP. This second edition includes two new chapters on the principles of parallel programming and programming paradigms, as well as new information on portability. For programmers wanting to gain proficiency in all aspects of parallel programming.

To catch a bug you have to think like a bug, and Barr (software programming manager) gets absolutely insectual. He gives practical tips on going beyond the debuggers by walking through the code, thoroughly understanding the code (all the code, including C, Python, Java, Perl, and x86 assembly language) and working down the food chain from the most likely to the least likely varmint that is loose in your or someone else's work. He includes classifications of bugs, their general sources, and ways to track their damage beyond the initial bite. Barr includes many examples and step-by-step methodologies.

Since the release of Microsoft Windows 98, Windows Script Host (WSH) has become increasingly popular as a tool for automating routine, daily PC tasks to save time and effort. But learning how to script with WSH has been difficult because of a lack of good documentation-until now. Microsoft Windows Script Host 2.0 Developer's Guide is the complete guide to automating routine Windows tasks. It covers all major features of Windows Script Host, as well as related topics such as how to access other automation objects. This book is ideal for WSH novices with basic programming knowledge, Microsoft Visual Basic(r) programmers, and programming experts who want to create WSH scripts to simplify working with their PCs.

Visual Basic Scripting (VBScript) and Windows Management Instrumentation (WMI) are vital tools for systems administrators grappling with the increasing complexity of Windows technologies. However, busy admins have been without a straightforward guide to scripting...until now.

Managing Windows® with VBScript and WMI explains how Windows administrators can effectively use VBScript to automate common administrative tasks and simplify complex ones. Detailed coverage of security concerns provides admins with the means for safely using VBScript in Windows environments. The book is organized around the problems you face daily, with reusable examples and coverage of Windows NT, Windows 2000, Windows XP, and Windows 2003.

This user-friendly reference demystifies scripting and then shows you how to produce new scripts from scratch. You will be producing useful scripts right away as you study the VBScript language and learn how to control nearly every aspect of the Windows operating system with WMI and the Active Directory Services Interface (ASDI). You will be able to build your own administrative Web pages and use advanced scripting technologies such as script encryption, scripting components, and script security. The book closes with still more ready-made example scripts accompanied by complete line-by-line explanations.
