Following the offical instruction to install Io language on Ubuntu 11.10 is confirmed to be problematic. I spent several hours to get Io installed successfully on my Ubuntu 11.10. Below shows how I get it all through.

I basically followed the off...

Utility, Helper, Common常被用来给静态的工具类命名，我一看到这样的东西就不由地皱眉头，不是说工具类没有用，而是因为看到太多工具类的误用了。下面是我在工作中遇到的两个例子。

有一次，看到下面的Java代码：

public void doSomething(){
    if(StringUtil.isEmpty(this.value)){
        // do this way ...
    }
    else{
        // do that way ...
    }
}

代码使用了StringUtil，觉得奇怪，难道内建的String功能不够强大，还要搞出个StringUtil？直觉告诉我，isEmpty是多余的，一定是哪里做错了什么......
