Not to shift the blame anywhere, but I think the problem is on the news
server. I have never seen that in other news servers and I've noticed posts
like that going back several monthes. I will alert CNN to this horrendous
Y2k glitch!

well, off the top of my head,
	s = sqrt(x*x+z*z)-1
	dist = sqrt(y*y+s*s)

Geez, this reminds me back in the day when I had a vase/bad texture fetish

On a side note, isn't it odd to see how hyper and crazy I was back in 1999?
