The Rails Cookbook is is packed with the solutions you need to be a proficient developer with Rails, the leading framework for building the new generation of Web 2.0 applications. Recipes range from the basics, like installing Rails and setting up your development environment, to the latest techniques, such as developing RESTful web services. Topics include: . Modeling data with the ActiveRecord library . Setting up views with ActionView and RHTML templates . Building your application s logic into ActionController . Testing and debugging your Rails application . Building responsive web applications using JavaScript and Ajax . Ensuring that your application is security and performs well . Deploying your application with Mongrel and Apache . Using Capistrano to automate deployment . Using the many Rails plugins Working with graphics

Object-oriented languages define objects (types of things) that know how to perform methods (specific actions). Functional languages treat programming problems like mathematical relationships. Ruby is flexible, meaning that you can program in any of these styles however, it is primarily object oriented, with some strong functional influence. This book focuses slightly more on the functional aspects of Ruby than some other books.

本程序实现任意偶数大小图像第二代双正交97提升小波变换 注1： 采用标准正交方法，对行列采用不同矩阵（和matlab里不同） 注2： 为了保证正交，所有边界处理，全部采用循环处理 注3： 正交性验证，将单位阵带入函数，输出仍是单位阵（matlab不具有此性质） 注4： 此程序是矩阵实现，所以图像水平分量和垂直分量估计被交换位置 注5： 此程序实现的是类小波（wavelet-like）变换，是介于小波包变换与小波变换之间的变换 注6： 此程序每层变换相对原图像矩阵，产生的矩阵都是正交阵，这和小波包一致 注7： 但小波变换每层产生的矩阵，是相对每个待分解子块的正交矩阵，而不是原图像的正交矩阵 注8： 且小波变换产生的正交矩阵维数，随分解层数2分减少 注9: 提升系数可以在MATLAB7.0以上版本，用liftwave( 9.7 )获取，这里直接给出，考虑兼容性 注10：由于MATLAB数组下标从1开始，所以注意奇偶序列的变化 注11：d为对偶上升，即预测；p为原上升，即更新

EZW Embedded Zero-tree Wavelets Encoding,video codecs from the EZW family which use a 3D version of EZW or SPIHT algorithms showed better performance than the MPEG-2 compression algorithm. These algorithms have many advantages inherent for wavelet based schemes and EZW-like coders. Their most important advantages are good compression performance and scalability.

AC97 Sample Driver and Related Code Samples. This directory contains a sample AC97 adapter driver and several related code samples. These samples need to be compiled with the Windows .NET or Windows XP build environment but are binary compatible with older operating systems like Windows 2000. To build the samples, enter any Windows .NET or Windows XP build environment and run build –cZ from this directory. The AC97 sample driver also runs in Windows 98 Second Edition or Windows Me, but the property page DLL and control panel application do not. For more information, please refer to the readme.htm files in each subdirectory. The INF file in the driver directory installs all of the samples in the subdirectories. The header file in this directory defines the private property used by each of the samples.

The iputils package contains ping, a basic networking tool. The ping command sends a series of ICMP protocol ECHO_REQUEST packets to as pecified network host and can tell you if that machine is alive and receiving network traffic.ipv6calc is a small utility which formats and calculates IPv6 addresses in different ways. It extends the existing address detection on IPv6 initscript setup or make life easier in adding reverse IPv6 zones to DNSor using in DNS queries like nslookup -q=ANY ipv6calc -r 3ffe:400:100:f101::1/48`
