So apparently some Microsoft Windows source code was leaked onto the internet.
According to the news article:
"Such access could also provide a competitive edge to Microsoft rivals, who would gain a much better understanding of the inner workings of Microsoft's technology."
Says Rob Enderle, a technology expert and principal analyst with the Enderle Group:
"It's more embarrassing than anything else because it makes it look like Microsoft can't control its code.''
There's a joke in here somewhere, but I'm not sure I need to say anything.
