最近在考虑是不是要做个论坛，因为有好几个项目需要。但是动手之前，还是先看看有没有现成的轮子。 论坛按理说应该是最常见的应用。比如大名鼎鼎的 JIVE (JAVA 论坛），那性能叫一个惊人（使用了各种cache 等优化） 。( I need a forum application for my projects, but before writing my own, I plan to seek for an open sourced Ruby forum which should be very commonly used application and many candidates. Recall the year 2006, when I first time dive into the open source project, the famous JIVE (java forum) impressed me by its extremely high performance )
google了一下， 找到三个开源的RUBY论坛： ( http://www.quora.com/What-is-the-most-mature-forum-software-built-in-Ruby-on-Rails)
1. beast (Rails 2.3.x ), altered beast (Rails3.x ) ( https://github.com/stiff/altered_beast )
2. forem (Rails3 ), 据说是最好的Ruby 论坛 (said to be the best one)
3. rborad. 据说也不错。(sounds good)
结果如下：
1.
altered Beast 是一个独立的forum. 如果你不用跟其他系统相结合，那么就用它吧！ 它有现成的皮肤，看起来似乎不错。不过不知道以后改版的话是否很麻烦。 ( altered beast is a standalone system . It's really a good choice if you don't need it to be a "plugin" or something similar and integrate it to existing system. It has its own outlooking&skin. )
缺点：一年没更新了。( not updated in this year)
2. forem. 非常棒，各种插件都是最流行最新颖的。作者也是个RUBY大牛。这个系统是一个插件，需要跟现有的系统进行集成，而且做成了一个GEM的形式。如果你没有现成的系统的话，就用不了。看你的需求了。 另外，前台的皮肤被剥离出来，做为一个独立的gem。如果你需要一个论坛插件，集成到现有系统当中，而且定制页面，那么forem是你的第一选择。 ( forem is awesome, it uses many of the cool and fancy, popular gems. the author is a top Ruby programmer. Forem is not a standalone application, but a rubygem, which need to be used as a plugin/module for existing system. and its outlooking is highly customizable/flexible. If you want your existing application have forum supported and the outlooking customized, then Forem is your first choice! )
3. rboard: 它的代码已经看不到了。官方站点只有一句话：rBoard曾经是非常棒的RUBY论坛，但是现在它被 Forem 取代了。 看起来很苍凉啊。( its source code is gone, there's only 1 README file left, saying: rboard was once a kick-ass forum, but now replaced by Forem... )
