The Object Test, a New PI, and More SHEEIT

"I've been trying to fix up the last project a colleague completed before heading for greener pastures," wrote Philip Tyre. "After finding this comment, I'm beginning to have bad thoughts about what I may find lurking around..."

//  Apparently, in at least on situation, a Statically declared public
//  variable will hold its value across different browser instances making calls to the
//  same web page.
//  For now, reset these variables on Page_PreInit.

"In Java, all classes extend the Object superclass by default and by design," Steve writes, "but just in case someone finds a way around that, we've got this unit test to make sure this magic code doesn't slip through the cracks."

/**
 * Tests if {@link XXXX} class extends {@link Object} class.
 */
@Test
public void testInheritance() {
    Assert.assertTrue("Class does not extends Object class.",
        instance instanceof Object);
}

"There are many ways to convert a number to a negative," writes Rafael L, "this, I suppose, is one of them."

// Convert to negative number
varInt := StrToInt('-' + IntToStr(varInt));

"We have some notoriously bad code in our project," wrote Robby Lann, " so much so that the Compiler throws a 'SHEEIT' Exception and advises us to start over."

"I work on a large website along with another part timer that sometimes makes minor changes to my code," writes Dave D, "usually there's no problem and we work well together, but today I opened up a piece of code I hadn't been into for over a year, only to find a new function added to object.
