在美国，汤姆·斯旺是“鼎鼎大名”的计算机图书作家，他的30余本计算机图书“本本热销”。这些热销图书中的很多种已经翻译成了中文简体版，同样也都成为了国内市场的畅销书。现在汤姆·斯旺再为Linux自由软件世界执笔，写下了Linux系统下C++编程方面的专著。书中介绍了在各种Linux系统下C++工具的差别及编程方法，介绍了面向对象式编程中常常遇到的类、包装、继承等常见课题，介绍了C++的字符串类、各种模板及算法库，还介绍了在X环境下，图形化软件的开发方式，等等。凭借多年写作的经验，汤姆·斯旺的著作，简单易懂，透视主题。他帮助读者，在轻松愉快的环境下，快速掌握相关的编程技术。
In the United States, Thomas Wong is the "famous" of computer book writer, and his more than 30 books in this computer "books selling." The selling of books have been translated into many Chinese Simplified, also the domestic market have become bestsellers. Thomas is now busy re-write for Linux free software world, wrote a Linux system programming in C++ monographs. The book describes a variety of Linux systems in C++ programming tools and the differences introduced object-oriented programming is often encountered in class, packaging, inheritance and other common issues, describes the C++ string class, a variety of templates and algorithm library, also introduced in the X environment, the graphical software development methods, and so on. With many years of writing experience, Thomas Wang s work, easy to understand perspective theme. He helps the reader, in a relaxed environment, to grasp the relevant programming.

如果把企业的数据比做生命所必需的血液，那么数据库的设计就是应用中最重要的一部分。有关数据
库设计的材料汗牛充栋，大学学位课程里也有专门的讲述。不过，就如我们反复强调的那样，再好的
老师也比不过经验的教诲。所以我们最近找了些对数据库设计颇有造诣的专业人士给大家传授一些设
计数据库的技巧和经验。我们的编辑从收到的130个反馈中精选了其中的60个最佳技巧，并把这些
技巧编写成了本文，为了方便索引其内容划分为5个部分
If the enterprise' s data comparing the blood necessary for life, then the database design is the application of the most important part of it. Voluminous material related to database design, university degree courses where there are special about. However, as we have repeatedly emphasized, even the best teachers, but the experience than the teachings. Therefore, we have recently looked for some pairs of database design is quite accomplished professionals who give you some design a database to teach skills and experience. Our editors from the feedback received, 130 of them selected the 60 best skills, and put these skills into the preparation of this article, in order to facilitate the indexing of its content is divided into five parts (2010-02-05, Unix_Linux, 55KB, 下载4次)

Linux 是一个源码开放的操作系统，无论是普通用户还是企业用户都可以编写自己的内核代码，再加上对标准内核的裁剪从而制作出适合自己的操作系统。目前有很多中低端用户使用的网络设备的操作系统是从标准 Linux 改进而来的，这也说明了有越来越多的人正在加入到 Linux 内核开发团体中。
一个或多个内核模块的实现并不能满足一般 Linux 系统软件的需要，因为内核的局限性太大，如不能在终端上打印，不能做大延时的处理等等。当我们需要做这些的时候，就需要将在内核态采集到的数据传送到用户态的一个或多个进程中进行处理。这样，内核态与用户空间进程通信的方法就显得尤为重要。在 Linux 的内核发行版本中没有对该类通信方法的详细介绍，也没有其他文章对此进行总结，所以本文将列举几种内核态与用户态进程通信的方法并详细分析它们的实现和适用环境。

本书并不是特意一本Linux 的内部手册相反它是对操作系统的介绍同时以Linux作为示例书中每一章遵循从共性到特性的原则它们将首先给出核心子系统的概叙然后进行尽可能的详细描叙 我不会用routine_X()调用routine_Y()来增加bar 数据结构中foo 域的值这种方式来描叙核心算法 你自己可以通过阅读代码发现它每当需要理解一段代码时我总是将其数据结构画出来这样我发现了许多相关的核心数据结构以及它们之间的关系 每一章都是非常独立的就象Linux 核心子系统一样当然有时它们还是有联系的比如说如果你没有理解虚拟内存工作原理就无法描叙进程 硬件基本概念一章对现代PC 做了简要介绍操作系统必须与硬件系统紧密结合在一起协同工作操作系统需要一些只能够由硬件提供的服务为了全面理解Linux 你必须了解有关硬件的基础知识 软件基本概念一章介绍了软件基本原理与C 程序语言讨论了建立Linux 这样的操作系统的工具并且给出了操作系统的目标与功能的概叙 内存管理这章描叙了Linux 如何处理物理内存以及虚拟存储技术 进程管理描叙了进程的概念以及Linux 核心是如何创建管理与删除系统中的进程 进程间及进程与核心间通讯以协调它们的活动Linux 支持大量进程间通讯IPC

Firepass - 一种隧道技术工具，通过它可以避开防火墙的规则约束，将数据流封装在合法的HTTP POST请求中。任何基于TCP/UDP协议的子协议可以通过它来穿越HTTP代理服务器对HTTP协议的严格审查。到目前为止，客户端和服务器端仅用PERL语言编写。服务器端作为一个CGI脚本运行在WEB服务器上。Firepass的主要特点是用户可以在外网使用几种方法安装服务器端脚本。用户无需在外网计算机上帮定任何端口。当服务端脚本被置于企业WEB服务器上，客户端脚本从外部网络和它通信时，Firepass也可适用于反弹作业。
Firepass-a tunnel technology tools, it can be avoided through the firewall rules to the data flow Packaging legitimate HTTP POST request. Any TCP/UDP protocol for the agreement to cross through its HTTP proxy server to the HTTP protocol rigorous review. So far, the client and server side only PERL language. Server as a CGI script is running on Web servers. Firepass are the main characteristics of network users who can use several methods to install the server-side scripting. Net users who need computer help any port. When the service was placed in the script-enterprise Web server, the client script from the network and its external communications, Firepass also apply to rebound operations.
