ruby 应用
1：FXRuby is a library for developing powerful and sophisticated cross-platform graphical user interfaces (GUIs) for your Ruby applications. It’s based on the FOX Toolkit, a popular open source C++ library developed by Jeroen van der Zijp. What that means for you as an application developer is that you’re able to write code in the Ruby programming language that you already know and love, while at the same time taking advantage of the performance and functionality of a featureful, highly optimized C++ toolkit. Projects Using FXRuby Projects using FXRuby include: BeERP is a commercial ERP built entirely with the FXRuby library. Discretizer is an interactive mesh creation tool. It can be used to create geometry and meshes for three dimensional flow simulations (CFD). foxGUIb is an interactive gui builder and codegenerator for FXRuby. This tool makes it easy to quickly build complex and good looking graphical user interfaces for Ruby. FXRI is a FXRuby Interface to RI that supports search-on-typing. FXRI is a small little program that tries to provide the desired information as fast as possible. fxtwitter is a simple Twitter client written in Ruby. FreeRIDE is an IDE for the Ruby programming language. http://opensource.csdn.net/project/lang/26?show=hots&p=5 MasterView™ - Rails-optimized (x)html friendly template engine http://masterview.org/ RubyScript2Exe http://www.erikveen.dds.nl/rubyscript2exe/index.html RUBY GUI框架:http://opensource.csdn.net/project/lang/26?tag=178

有一个全新的项目，因为考虑到将来的数据扩展性能，所以考虑用Cassandra做数据存储，前端用Lighttpd + FastCGI + Rails。在使用Cassandra的时候，觉得有一些东西可能大家都需要，就写了一个简单的指南。因为内容比较长（16页），就弄了个PDF文件给大家下载。

ruby中单引号和双引号的意义有所不同，双引号包围的字符作变量替换，单引号包围的变量不做替换
也可以使用 %q 和 %Q 来生成字符串对象。%q 相当于单引号，%Q相当于双引号。
举例如下：
irb(main):010:0> "show trsult: #{1*3}"
=> "show trsult: 3"
irb(main):011:0> 'show trsult: #{1*3}'
=> "show trs ......
