COOKBOOK - Böcker

"Perl Cookbook" is a comprehensive collection of problems, solutions, and practical examples for anyone programming in Perl. The book contains hundreds of rigorously reviewed Perl "recipes" and thousands of examples ranging from brief one-liners to complete applications. The second edition of Perl Cookbook has been fully updated for Perl 5.8, with extensive changes for Unicode support, I/O layers, mod_perl, and new technologies that have emerged since the previous edition of the book. Recipes have been updated to include the latest modules. New recipes have been added to every chapter of the book, and some chapters have almost doubled in size. Covered topic areas include: manipulating strings, numbers, dates, arrays, and hashes; pattern matching and text substitutions; references, data structures, objects, and classes; signals and exceptions; screen addressing, menus, and graphical applications; managing other processes; writing secure scripts; client-server programming; Internet applications programming with mail, news, ftp, and telnet; CGI and mod_perl programming; and Web programming.Whether you're a novice or veteran Perl programmer, you'll find Perl Cookbook, 2nd Edition to be one of the most useful books on Perl available. Its comfortable discussion style and accurate attention to detail cover just about any topic you'd want to know about. You can get by without having this book in your library, but once you've tried a few of the recipes, you won't want to.

Concise but thorough, this second edition of C# Essentials introduces the Microsoft C# programming language, including the Microsoft .NET Common Language Runtime (CLR) and .NET Framework Class Libraries (FCL) that support it. This book?s compact format and terse presentation of key concepts serve as a roadmap to the online documentation included with the Microsoft .NET Framework SDK; the many examples provide much-needed context. This new edition has been updated to cover the final release of the C# language. In addition to overviews of C#, the CLR, and the FCL, this new edition of C# Essentials covers: *Every C# language element and its syntax, in reference format, including new keywords *The major C# datatypes, with code examples *Common C# programming tasks *Interoperation with legacy Win32 APIs and COM components, and the use of C/C++ style pointers within the managed context of the CLR *Common development issues C# Essentials is an easy way for experienced programmers to evaluate and get up to speed quickly on the language best suited to developing web applications and services on the new Microsoft .NET platform.

The DNS & BIND Cookbook presents solutions to the many problems faced by network administrators responsible for a name server. Following O'Reilly's popular problem-and-solution cookbook format, this title is an indispensable companion to DNS & BIND, 4th Edition, the definitive guide to the critical task of name server administration. The cookbook contains dozens of code recipes showing solutions to everyday problems, ranging from simple questions, like, "How do I get BIND?" to more advanced topics like providing name service for IPv6 addresses. It's full of BIND configuration files that you can adapt to your sites requirements. With the wide range of recipes in this book, you'll be able to * Check whether a name is registered * Register your domain name and name servers * Create zone files for your domains * Protect your name server from abuse * Set up back-up mail servers and virtual email addresses * Delegate subdomains and check delegation * Use incremental transfer * Secure zone transfers * Restrict which queries a server will answer * Upgrade to BIND 9 from earlier version * Perform logging and troubleshooting * Use IPv6 and much more.These recipes encompass all the day-to-day tasks you're faced with when managing a name server, and many other tasks you'll face as your site grows. Written by Cricket Liu, a noted authority on DNS, and the author of the bestselling DNS & BIND and DNS on Windows 2000, the DNS & BIND Cookbook belongs in every system or network administrator's library.

When Object Oriented programming (OO) first appeared, it was a revelation. OO gave developers the ability to create software that was more flexible and robust, but as time went on and applications became more sophisticated, too, certain areas of "traditional" OO architectures were found wanting. Aspect-oriented programming (AOP) addresses those issues by extending the OO approach even further. Many developers are interested in AOP--especially in AspectJ, the open source extension of the Java programming language that explicitly supports the AOP approach. Yet, although AspectJ is included with Eclipse, the increasingly popular open source IDE for Java, finding a practical and non-theoretical way to learn this language and other AOP tools and techniques has been a real problem. Until now. The AspectJ Cookbook offers a hands-on solution--in fact, several--with a wide variety of code recipes for solving day-to-day design and coding problems using AOP's unique approach. AOP allows the global properties of a program to determine how it's compiled into an executable program. Before AOP, important program design decisions were difficult to capture in actual code.Instead, the implementation of those design decisions--known as "aspects"--were scattered throughout, resulting in "tangled" code that was hard to develop and maintain. AOP has been compared to the manufacturing of cloth, in which threads are automatically interwoven. Without AOP, programmers must stitch the threads by hand. The AspectJ Cookbook shows readers why, and how, common Java development problems can be solved by using AOP techniques. With our popular problem-solution-discussion format, the book presents real world examples to demonstrate that AOP is more than just a concept; it's a development process that will benefit users in an immediate and visible manner. If you're interested in how AOP is changing the way software is developed, and how you can use AspectJ to make code more modular, easier to develop, maintain, evolve and deploy, this is the book that really delivers.

Written by key members of Juniper Network's ScreenOS development team, this one-of-a-kind Cookbook helps you troubleshoot secure networks that run ScreenOS firewall appliances. Scores of recipes address a wide range of security issues, provide step-by-step solutions, and include discussions of why the recipes work, so you can easily set up and keep ScreenOS systems on track. ScreenOS Cookbook gives you real-world fixes, techniques, and configurations that save time -- not hypothetical situations out of a textbook. The book comes directly from the experience of engineers who have seen and fixed every conceivable ScreenOS network topology, from small branch office firewalls to appliances for large core enterprise and government, to the heavy duty protocol driven service provider network. Its easy-to-follow format enables you to find the topic and specific recipe you need right away and match it to your network and security issue.Topics include: * Configuring and managing ScreenOS firewalls * NTP (Network Time Protocol) * Interfaces, Zones, and Virtual Routers * Mitigating Denial of Service Attacks * DDNS, DNS, and DHCP * IP Routing * Policy-Based Routing * Elements of Policies * Authentication * Application Layer Gateway (SIP, H323, RPC, RTSP, etc.,) * Content Security * Managing Firewall Policies * IPSEC VPN * RIP, OSPF, BGP, and NSRP * Multicast -- IGPM, PIM, Static Mroutes * Wireless Along with the usage and troubleshooting recipes, you will also find plenty of tricks, special considerations, ramifications, and general discussions of interesting tangents and network extrapolation. For the accurate, hard-nosed information you require to get your ScreenOS firewall network secure and operating smoothly , no book matches ScreenOS Cookbook.
