One of your key system daemons has just crashed (SEGFAULT). Restarting it causes yet another crash; what do you do? If you know C coding, you start doing stack traces. If you have a support contract, you call them up.
I'm sorry, but I live in the real world. I can't justify the risk of lost time involved with the options you provide. I will make a copy of the core-dump and the data currently "live" with that daemon, before rolling back to a backup from disk, VTL or tape.
99% of the time, the problem is gone, because 99% of the time the problem will be caused by bad data triggering a/the bug. And most likely, the copy+rollback took about the same amount of time as the phone-call to support would have taken (most often less), and unless you are very experienced at debugging other peoples code it is almost guaranteed to be faster than pulling out strace, gdb and the source.
Of course, there is a reason I say "make a copy of..". After rolling back and getting things running again, I am very much interested in figuring out what went wrong. But now I have plenty of time to either do the debugging, or seek out someone who knows how...
Reduced noise is a second advantage of the configuration - part of the loud 'slapping' noise associated with conventional helicopters arises from interaction between the airflows from the main and tail rotors, which in some designs can be severe.
Why do electrical engineers always insist on using non-SI units? The correct unit for energy is the Joule, or Watt-second.
Uhm. 1 Joule == 1 Ws. 1 Wh = 3600 Ws. 1 kWh == 1000 Wh
But at first, when Orkut and Gmail were invite-only[...]
Orkut was invite only? That must have happened after Google took over. When I signed up with the service the sign-up was absolutely open.
All the data inside the hard drive is claimed to be encrypted, though this isn't actually true. The only thing that has been overwritten is the MBR.
Attempt by most users and technicians to fix the infection will be to run “fixmbr” to restore the MBR with a clean copy. Sadly it is not possible, because the rootkit wipes out the whole partition table section from the first sector of the hard drive - it is copied out to the fifth sector along with whole original MBR.
