This new version of Ruby 1.91 is said to fix the heap overflow vulnerability in p243 and, in addition, includes over 100 bug fixes. So, it is suggested that you upgrade to p376. (Changelog) I, of course, updated mine:
wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p376.tar.bz2 tar -xvf ruby-1.9.1-p376.tar.bz2 cd ruby-1.9.1-p376 ./configure --bindir=/usr/bin --sbindir=/usr/sbin/ make -j3 make install



这脚本的好程序多吗?
RoR(Ruby on Rails)现在是公认的最效率的web开发框架,因为Ruby的语法很简洁,再加上RoR开发MVC(Model-view-controller)分离的理念。而且平常需要写个程序完成某项任务的时候,用Ruby往往能节省一些写代码时间,再加上Ruby有强大的Gem软件包管理(类似yum),而且各种应用接口很多(尤其是写点web爬虫什么的,很方便)。
