How do you add more space to a Fedora (LVM) partition?

Does Windows 8 allow multiboot when installing from a mounted ISO?
I just downloaded Windows 8 and am itching to install it. The installation says it will clean everything out.

Find which HT-cores are sharing a physical core from /proc/cpuinfo
There is a computer with two "Xeon(R) CPU X5550 @ 2.67GHz" CPU. The Hyper-threading is enabled, so it looks like 16-core system, but really there is only 8 physical cores.

Is it normal for a Dell Inspiron 530 to have is fan to spin up 3 times before it POSTS?
I picked up an used Dell 530 desktop. It seems to work, but it has an odd pattern of powering up the case fan (which might be faulty - it sounds like a jet engine) 3 times, while blinking the power light. No other fan seems to activate during the time, and it goes silent after that. I'm wondering, …

A scratched CD cannot be copied, but can be viewed by VLC or jetAudio - how?
I've a badly scratched VCD whose content can't be copied to hard disk. My OS is Windows 7 Ultimate x64. Windows can't copy the 750 MB video file. I also tried CDCheck and Recover Disc.
