"I just inherited a PHP application and discovered this," writes David Green. "I don't know what's worse: the fact that it says add but is performing subtraction, or that I can't find the accompanying addnoise() function."

public function addfunk($one, $two) {
    $val = $one - $two;
    return $val;
}

 

"I know what a Boolean is, and a know what Mutable means," Casey Borders writes, "yet I have no idea what a MutableBoolean is."

class MutableBoolean
{
    public boolean value = true;

    public MutableBoolean(boolean v)

        value = v;
    }
}

"I was browsing through the morass that is our excessively layered code base when I stumbled upon this gem of genius programming," Sebastian writes, "I started sobbing a little and people looked at me like I was some weirdo."

    return MAX_NUMBER_ATTACHMENTS != -1; 
}

public bool IsOk
{
  get
  {
    return value >= 0;
  }
}


public bool IsNotOk
{
  get
  {
    return !IsOk;
  }
}

    '***** 04/21/2004 - corrected function IsObjNothing expression type
    'IsObjNothing = (TypeName(poObject) = Nothing)
    IsObjNothing = (TypeName(poObject).ToUpper = "NOTHING") End Function

 

"While taking a stroll through the code on a new project, I came across a fantabulous override of ToString," Jay writes, "I guess you never know when this will be null."
