2 Wrongs Making a Right: (false && false) = true

I just had one of those times when I thought I totally lost the ability to do simple logic. Take a look at this screenshot:

I'll break it down: req.readyState = 4, and batch.async = false.

Last time I checked 4 = 4. So blatantly (4 != 4) is false. And false && false is blatantly uber false, as true as Alice Cooper covering Barbie Girl.

So seeing firebug step through if (false) and onto the return statement made about as much sense as trying to raise Schrodinger's cat in a séance.

I think it's another quirk in Firebug. This time it's simply something funky going on with "step over".

The moral is: Firebug sometimes lies to you about where the current line is.

This is all part of me adapting DWR so that it can be used as a connector between Jaxer and some Java server. More on that in a bit.

Mitchell definitely needed to resign. He was doing such a bad job and i did not trust him at all. I am not sure what he was thinking sometimes. I think this is the best.<a rel="shelf" href="http://www.themodernline.com">shelf

The operation cost just under $500, and no one was killed, or even hurt. In that same time the Pentagon spent tens of millions of dollars and dropped tens of thousands of pounds of explosives on Viet Nam, killing or wounding thousands of human beings, causing hundreds of millions of dollars of damage. Because nothing justified their actions in our calculus, nothing could contradict the merit of ours. Funeral Urns
