yes, to many (including me) the solution to many problems involves government action or regulation. you conveniently ignore that people taking that stance are generally (implicitly or explicitly) talking about legislating in favor of the interests of the general population, not of private interests (the only ones this law is trying to protect).
"By default, Windows XP SP2, Windows XP SP3 and Windows XP Professional x64 Edition SP2 do not have a listening service configured in the client firewall and are therefore not affected by this vulnerability"

On an unrelated topic, I have an NVIDIA GeForce 7300 GT and up until KDE4.2.1 had experienced pretty appalling performance but, with the latest upgrade this week, thing have improved noticeably. I'm not sure if this is due to the KDE update (4.2.1 to 4.2.2), the NVIDIA driver update (180.41 to 180.44) or something else entirely but, finally, the last KDE4 issue really annoying me has vanished as well, so it looks like there's only happy times ahead.
