This book is for all those people.
• For the person who thinks programming is too hard
• For the person who gets bogged down when writing or changing
larger scripts (our analyst)
• For the person who knows the wrong languages well (our programmer):
languages like Java, C#, C++, and C are perfectly fine
languages—in their niche.
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

Channel transmission simulator
Channel transmission simulator
％
％ inputs:
％ sig2 - noise variance
％ Mt - number of Tx antennas
％ Mr - number of Rx antennas
％ x - vector of complex input symbols (for MIMO, this is a matrix, where each column
％ is the value of the antenna outputs at a single time instance)
％ H - frequency selective channel - represented in block-Toeplitz form for MIMO transmission
％ N - number of symbols transmitted in OFDM frame
％
％ outputs:
％ y - vector of channel outputs (matrix for MIMO again, just like x matrix)
％ create noise vector sequence (each row is a different antenna, each column is a
％ different time index) note: noise is spatially and temporally white
A very smaller script interpretor that java based system. Can work on j2se / j2me / win C++ platform ,the major goal is used to build more flexible j2me game. Script language s phrase like as BASIC .
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.
This tutorial illustrates how to use the versatile Eclipse environment to facilitate
development of Globus Toolkit V4 (GT4) grid services. The tutorial is written for
Web service and grid developers who would like the convenience of
orchestrating the whole grid service development process from within the
Eclipse IDE on Windows-based platforms.
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`
