comment Why does my microwave kill the Wi-Fi?
The radiaton interference is unlikely from the coherent standing wave microwaves in the oven getting out but the imperfect magnetron making the whole case act as a microwave antenna with low coherence (will cause noise but can't heat anything)

comment Transferring “large” file off of MS-DOS 5.0 Machine (without removing HDD)
I just feel bad for the poor guy using a 1980's dosbox as his daily workstation

If the computer is far away from you, how will you swap floppy 1 for floppy 2?

comment How to delete “System Volume Information” from an external drive when the feature isn't even turned on
None of those uses are particularly useful for a drive being used as a basic storage drive just because it happens to be NTFS.

comment How do I remove a Linux partition and expand the Windows partition to consume the Linux partition space?
You forgot to expand the NTFS partition. Personally I would do that in the beginning just because I trust ntfs-3g (and haven't had issues ever), you can also wait until you fix the bootloader before doing this, but I don't see the point (if windows booted just fine before with grub) . Note that it doesn't require deleting the linux partition to proceed with the windows 7 bootloader recovery process.

comment Which of the Windows updates are really necessary?
I'd also like to add the common wisdom that storage is dirt cheap and you shouldn't be worried about the small amount of space used by the backups. 1 TB drives are well under $100. It's better to buy storage than compromise (potentially) system stability.

comment Can touching any hardware inside a running PC be dangerous for you?
The AT-standard only allowed for "hard" power switches, e.g. the switch physically cut the mains supply to the PSU like a light switch. The ATX standard defined a "soft" power switch that allows the motherboard to control the PSU power by supplying the proper voltage on the control line. The downside is that the PSU is required to provide a small line that is constantly on - to allow the computer to power up. The plus side is that you can shutdown/restart/powerup the computer in software.

comment What are sxxx.vmdk files and how do I get rid of some of them?
I would guess those are VMWare snapshots of a running system in order to restore from a previous state. When you shutdown your VM's are you using the snapshot/restore feature?

comment Torrent Tracker for Private Downloads
Lol, yeah, I usually just go with scp, but this kind of needs to spread to a lot of people at once and I'd rather not give everyone a user account on my host.

comment Why is my dual-core CPU recognized as a quad-core one?
The best way to think of HT is a "core-and-a-half" it shares many more resources with its brother than the seperate cores do. However it is capable of executing a thread "on its own" and the OS treats it as a thread execution unit (which you associated with a core).

comment Do x86 applications use 64 bits addresses in x64 operative systems?
You are forgetting that every page table entry has both a virtual part and a real part, both will be doubled when going from a 32 bit system to a 64 bit system (actually a little more because with 4KB pages we are masking the last 12 bits, so we are really going from 24 bits to 52bits in the PT a factor of 2.16). However you right that if we are using 32bit VA to 64 bit PA to begin with then the total change will be only be two fold

@soandos assuming we keep the same page size (of course that is a maybe) it will quadruple the current page table size. Think about it logically - if we pad pointer in our 32bit PT with 0's just for the hell of it it will at least quadruple in size (assuming a flat PT, which is reasonable enough for a size approximation)

comment Do x86 applications use 64 bits addresses in x64 operative systems?
@soandos, while it is true that for an individual application the difference in pointer size will affect the memory footprint minimally. On the os side - the 64 bit pointer increase will quadruple the size of the page table required. Page tables on a loaded 32 bit system can reach 50MB, quadrupling that is not a small difference.

comment How to determine the WiFi channel from Mac command line?
Mac OS doesn't include wlan-tools (that has iwconfig among other things) and a quick google search on iwconfig apple and similar tells me that you might be SOL.

comment Can Screwdrivers With Magnetic Tips Cause Damage To Electronics?
Hard drive disks are enclosed in an aluminum box that acts as a shield. External fields do not get inside up to the approximation that it acts a perfect conductor.

comment How is a 1GPBS 64-bit ethernet card different from a 32-bit one?
64 Bit PCI is probably referring to PCIX a 64 Bit extension to the PCI bus primarily used in servers
