The beauty of open source is making code freely available. The curse is trying to organize the chaos that code development can evolve into. CVS, the Concurrent Version System, is an open source tool for managing and distributing source code. It allows multiple users dispersed over a wide geographic area to work on the same file at the same time, using a shared directory. Under CVS, multiple users can check out files from a directory tree, make changes, and then commit those changes back into the directory. CVS is a pivotal tool on many projects involving information or software, whether in-house or conducted over the Internet. The CVS Pocket Reference is a quick reference guide to help administrators and users set up and manage source code development. This small book delivers the core concepts of version control along with a complete command reference and guide to configuration and repository set up. The book includes: A version control primer that teaches the general concepts of version control and how it applies to CVS. Instructions on how to install and configure CVS for Unix®-like operating systems. Administrator and user sections, with complete listings of their respective commands and options for configuring and using CVS. Details on how to import files from RCS and SCCS directories into CVS. References to related useful materials. Much more than a quick list of commands and options, this little book is packed with a surprising amount of detail--including an overview of background concepts, thorough descriptions on how to use and administer a CVS repository, and discussions of CVS-related files and how to manage them--all in a convenient reference format. This edition covers the CVS 1.11 and includes new commands for querying a central CVS repository, new configuration parameters, and new options for setting up a server for remote access. The book is a perfect companion for open source developers. The CVS Pocket Reference also contains tips on common tasks, such as converting projects from other revision control formats to CVS. It's an absolute must for developers who need an on-the-job guide for quick answers to CVS dilemmas.

One of Java's most striking claims is that it provides a secure programming environment. Yet despite endless discussion, few people understand precisely what Java's claims mean and how it backs up those claims. If you're a developer, network administrator or anyone else who must understand or work with Java's security mechanisms, Java Security is the in-depth exploration you need.Java Security, 2nd Edition, focuses on the basic platform features of Java that provide security--the class loader, the bytecode verifier, and the security manager--and recent additions to Java that enhance this security model: digital signatures, security providers, and the access controller. The book covers the security model of Java 2, Version 1.3, which is significantly different from that of Java 1.1. It has extensive coverage of the two new important security APIs: JAAS (Java Authentication and Authorization Service) and JSSE (Java Secure Sockets Extension). Java Security, 2nd Edition, will give you a clear understanding of the architecture of Java's security model and how to use that model in both programming and administration.The book is intended primarily for programmers who want to write secure Java applications. However, it is also an excellent resource for system and network administrators who are interested in Java security, particularly those who are interested in assessing the risk of using Java and need to understand how the security model works in order to assess whether or not Java meets their security needs.
