comment Is there a way to activate Windows 7 when it's saying my license code is already in use?
Just so it's said: not all OEM install discs are the same, unless something's changed in the past couple of years. Last time i tried a Dell setup disc, for example, it refused to install unless it detected it was running on a Dell. It'd be possible (and MS would probably prefer) to be even more specific than that.

For reference, '/' is a slash. '\' is a backslash. (Pet peeve.)

comment Can a 7 days full 100% CPU load “burn-in” / “stress test” damage a modern notebook?
The Dell laptops i've had tended to get really hot too.

comment Figuring out how many megabytes go into gigabytes?
@Jonathan.: The fact that (a) 1024 is a power of two, and computers (and computer engineers) like working in powers of two; and (b) it's not contradicting anything -- since there's no SI unit called the "byte", it doesn't matter how SI defines its prefixes.

@user530873: Not if you want people to actually say them, they're not. :P I refuse to say the word "gibibyte" unless i'm consciously trying to sound stupid.

comment Is it safe to power on a motherboard outside of its case?
It seems like there are kinda two meanings for "ground". In an electronic circuit, your normal "ground" pin is often a local ground...just a voltage sink, electron pool, or what have you...and basically everything uses it. The case, on the other hand, provides a "chassis ground", an honest-to-goodness ground that connects to the third blade/pin on your power cord (though it probably does this indirectly through the power supply's own chassis ground).

comment How does virtualizing differ from emulation, in terms of structure?
@tonsbons: By definition. :P An emulator doesn't do the exact same thing -- it emulates everything from the CPU on up. Bochs, for example, is an emulator. Virtualization is thinner; a hypervisor runs the guest OS on the physical CPU (basically tricking the guest into thinking it owns the CPU). Since the guest doesn't have the privileges it thinks it has, though, it triggers "faults" when it attempts to do kernelly stuff. The hypervisor watches for those faults, and twiddles the virtual hardware to make it look to the guest like those operations actually happened.

comment Will ImgBurn -> ISO -> new DVD make an identical copy of a Windows 7 install DVD?
Have you tried creating an ISO and then installing in a VM? Seems to me that'd at least indicate whether the ISO is usable. (Scratch that: just reread and saw you don't yet have a DVD to rip.)

comment How do i make Chrome use an IPv6 address from my hosts file?
@MichaelHampton: FF and IE both work. Chrome doesn't. Haven't tried any other browsers (Opera being the only other one that comes to mind). I can use FF if need be, but....eh.

comment If DOS is single-tasking, how was multitasking possible in old version of Windows?
@supercat: The problem is exactly how existing real-mode code assumed segments work. To clarify, i don't mean "assume" as a bad thing -- it's quite valid to assume segments work as in the 8086, when the OS you're writing for is basically using the processor as a fancy 8086. But protected mode couldn't possibly support all of those assumptions and still widen the address space. Even today, it still can't -- virtual 8086 mode basically just emulates real mode, with its associated limitations (and a few more related to the rationale behind protected mode in the first place).

comment If DOS is single-tasking, how was multitasking possible in old version of Windows?
@david25272: Nearly any processor "supports" preemptive multitasking; all it takes is the ability to store and load registers, and support for hardware interrupts. But without the ability to protect processes from each other, it's more trouble than it's worth -- it's basically just half-assed threading, with all the issues that entails. As for the PDP-8, no one cares. :) It's quite irrelevant here, being not a DOS or Windows machine.
