Recently I see a lot of negative posts on SitePoint against cloud computing. Cloud computing is fine. The problem is the huge user base of Gmail.
If a problem like this occurs to a smaller company that offers SaaS services, it won’t have such a big impact.
If you should always have access to your emails, backup your emails or go offline with google gears and stop complaining :)
If you have messed up the file permissions and ownerships of installed packages on your Linux box for any reason, you can fix these for all the packages that were installed by rpm. This method will only work for RedHat, CentOS, Fedora and other rpm based Linux distribution.
This will restore ownerships and then restore permissions for all installed packages

BBC reports that US and Russian communications satellites have collided in space in what is thought to be the biggest incident of its kind to date.
The US commercial Iridium spacecraft hit a defunct Russian satellite at an altitude of about 800km (500 miles) over Siberia on Tuesday, Nasa said.
The risk to the International Space Station and a shuttle launch planned for later this month is said to be low.
The impact produced a cloud of debris, which will be tracked into the future.
Since the Soviets launched Sputnik in 1957, it is estimated about 6,000 satellites have been put in orbit.
Satellite operators are all too aware that the chances of a collision are increasing.
The Americans are now following the debris path from the impact. It is hoped (!) that most of it will fall to Earth and burn up in the atmosphere.
