In recent years, the UNIX operating system has seen a huge boost in its popularity, especially with the emergence of Linux. For programmers and users of UNIX, this comes as no surprise: UNIX was designed to provide an environment that s powerful yet easy to use. One of the main strengths of UNIX is that it comes with a large collection of standard programs. These programs perform a wide variety of tasks from listing your files to reading email. Unlike other operating systems, one of the key features of UNIX is that these programs can be combined to perform complicated tasks and solve your problems. One of the most powerful standard programs available in UNIX is the shell. The shell is a program that provides you with a consistent and easy-to-use environment for executing programs in UNIX. IF you have ever used a UNIX system, you have interacted with the shell.

upsd_flash.c These functions are provided to help you develop your initial code. They are optimized for speed rather that size. As a result, you will see very few nested function calls. IF speed is not critical, you can use function calls for common tasks (like dat polling after writing a byte to Flash) The penalty is the extra processor time to make the nested calls.

The Unisoft software module GERBER CONNECTION (CNC-BRIDGE). GERBER CONNECTION has all the features of VIEW-MARKUP and adds the ability to open multiple gerber file layers and add information to components. It is always the preference to use the CAD data vs. gerber data. IF you do not have the CAD data then GERBER CONNECTION can help.

多项式曲线拟合 任意介数 Purpose - Least-squares curve fit of arbitrary order working in C++ Builder 2007 as a template class, using vector<FloatType> parameters. Added a method to handle some EMathError exceptions. IF do NOT want to use this just call PolyFit2 directly. usage: Call PolyFit by something like this. CPolyFit<double> PolyFitObj double correlation_coefficiant = PolyFitObj.PolyFit(X, Y, A) where X and Y are vectors of doubles which must have the same size and A is a vector of doubles which must be the same size as the number of coefficients required. returns: The correlation coefficient or -1 on failure. produces: A vector (A) which holds the coefficients.

Hibernate: A Developer s Notebook shows you how to use Hibernate to automate persistence: you write natural Java objects and some simple configuration files, and Hibernate automates all the interaction between your objects and the database. You don t even need to know the database is there, and you can change from one database to another simply by changing a few statements in a configuration file. IF you ve needed to add a database backend to your application, don t put it off. It s much more fun than it used to be, and Hibernate: A Developer s Notebook shows you why.

This book explains how to write, install, and debug device drivers for Windows 2000. It is intended to be a companion to the Microsoft DDK documentation and software. Windows 2000 represents a major improvement to previous versions of Windows NT. Device drivers for Windows 2000 may be designed for the new Windows Driver Model (WDM) architecture. IF so, the driver will be source compatible with Windows 98. This book covers the new WDM specIFication. This book will also prove useful to those studying the internals of Windows 2000, particularly the I/O subsystem and related components.

一款基于J2EE轻量级架构的社区系统,具有如下特点: 表示层:基于Apache Tapestry组件化页面技术,对客户界面进行模块设计。由于页面模板中只有简单的类似IF-else和for 循环逻辑,并且所有标签都是标准的HTML标签,因此页面可以放在任何所见所得的HTML编辑器中进行很轻松的编辑、美化。当然,Tapestry只是整个系统的表现部分,如果需要,此部分也可由其它技术实现,如JSP,Velocity等。 权限系统:在客户界面与业务核心层间,存在一套完整的权限系统。每个用户在系统中都有自己的权限,这些权限细致限定了该用户可以使用哪些服务或者可以访问哪些业务对象。 过滤器系统:此系统由一系列过滤器组成,对表示层要显示的社区内容执行过滤。 社区核心层:这里完成几乎所有的业务逻辑。 后台数据库系统:存储社区各项数据。数据层服务由Hibernate提供数据连接。 模块化、可配置、伸缩性强:您可广泛程度上的定义多数社区子系统:如用户、组、权限系统、过滤器、拦截器、等级积分算法、社区属性(如体力值、魅力值)等。
