HP ProBook 4520s install driver for RaLink RT3090 Wireless in KUbuntu

There is a Novell SUSE Linux on my HP4520s but I like free software. In spite of that it was bought with my notebook I decided to use Kubuntu. I installed it successfully. Only one that was not discovered was RaLink RT3090 Wireless adapter. To solve that problem I found a solution.

Iran arrests 'nuclear spies,' intelligence chief says

Does it mean that War began?

(CNN) -- Iran arrested a number of "nuclear spies," its intelligence minister said, in the wake of widespread reports of a sophisticated new computer virus that may have been aimed at Iran.
Intelligence Minister Heydar Moslehi made the announcement Saturday, without giving any details, Iran's semiofficial Mehr news agency reported.
Iran is widely thought to have been the most likely target of the Stuxnet virus, which a top computer security expert told CNN was "the most complex piece of malware in the history of computing."
Tehran has insisted its controversial nuclear program had not been compromised by the virus.

or just text version:
Firefox is in my opinion the best browser ever made until now. It includes:-improved tabbed browsing-pop up blocking
-integrated Goggle search
-enhanced privacy controls
-built-in phishing protection
-online spell checking
-lots of themes, interfaces, and extensions/addons
Mozilla Firefox officially supports:
-Microsoft Windows
-Linux
-Mac OS X
