comment Could a bad energy grid system cause a BSOD back in the year 2000?
A really good PSU in the computer saves you from most problems. The worst that can happen then is a power shutdown. However, a lot of desktops have bad PSUs made for $30 in a Chinese sweatshop and called Sunshine or something like that. Those don't protect you from anything.

comment What is the difference between BIOS and firmware?
Video-BIOS is from the days when BIOS loaded Option ROMS from peripherials into the BIOS. This is how the various BIOS video INT services are provided.

comment Are CPU clock ticks strictly periodic?
I have read that in multi-core CPUs the cores are also using offset clocks because it helps avoid radio noise, helps with power distribution, and avoids the cores building harmonics.

comment Version `GLIBCXX_3.4.15' not found in CentOS (in file /usr/lib/libstdc++.so.6)
I have not looked to see of they have it but have you tried EPEL

comment Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive?
I agree that disabling swap can be a good idea. Anyone who's used Linux and had Evolution email run away with 3.5 GB of RAM would rather have Evo die than sit and wait for the laptop to stop swapping.

comment What's the difference between mobile and desktop processors?
@MattH: Having some well chosen extra instructions can help a lot. But NOT just "the instruction set is larger." After all, almost half the ISA in a modern Intel x86 chip isn't even used! Old compatibility instructions in 16 bit. Segment registers. An initial power-on sequence straight out of 1980.

comment File sizes in Windows not making sense
@FabricioAraujo: Traditionally we measured things in ounces, pounds, troy ounces, slugs, tons, stones, pinches, etc. And you had to know what you were measuring to know how big the unit was. Gold used different ounces from flour. Tradition is not a reason to do things the wrong way.

comment File sizes in Windows not making sense
@phyrfox: Mega is 1 million no matter what unit it applies to. This is the only thing that makes sense.

comment File sizes in Windows not making sense
@phyrfox: 1 MHz of CPU is 1 million cycles, not 1,073,741,824 cycles. 1 Mbps of network traffic is also 1 million bits.

comment Why do SSDs have weird sizes?
What is really weird is that non-SSD drives have been non-standard sizes since forever. What is advertised as an 80GB drive might vary from exactly 80GB by many megabytes. Anyone who runs RAID arrays knows this.

comment Why do SSDs have weird sizes?
Except that some SSDs now use TLC (tri-level) states and actually need MORE reserved space than previous drives because of the higher error rates. The Magician software for my Samsung EVO drive recommended reserving more space when I did the setup. So instead of a terabyte its only 920 GB.

comment Historical: why is the first GUI terminal in linux Ctrl-Alt-F7?
GUI was added later. Init system sets up the terminals first so they get 1-6. Then X starts up on 7.

comment Windows 8.1 comes with SQL Server and Visual C++?
MS SQL Compact is a little bit like SQLite. Or maybe a better comparison is the old JET database engine.

comment What is the danger of inserting and browsing an untrusted USB drive?
Yes they do. Almost all of them have small resettable fuses. I found this electronics.stackexchange.com/questions/66507/… to be kind of interesting.

comment What is the danger of inserting and browsing an untrusted USB drive?
@sylvainulg: I meant about the filesystem types. While Windows only mounts three or four FS types, Linux will try whatever it has available, which can be a lot of filesystems.

comment OCZ SSD drive reviews are very polarized, whereas Corsair and Sandisk reviews are mostly great - What's up with OCZ?
I don't believe the OCZ reviews are all fake. For example, I have used three OCZ drives and I have liked all of them. My current Vertex is running great.

comment Can my Windows 8 computer turn on by itself?
If the operating system wanted to, it could set a timer for every 15 minutes, wake up just a little bit to check on things like reading email for example and then sleep again. Just like a cell phone does.

Windows can set those BIOS timers you mention. It is used for scheduled tasks.

comment Tired of waiting for www.google-analytics.com — can a browser setting “opt me out”?
0.0.0.0 is a valid IP address. At least, software had better NOT be special casing it. The default route is 0.0.0.0/0. Very different from 0.0.0.0/32.

comment Why is a .ISO called a .ISO?
Wanted to point out that some programs used different extensions such as CDR or IMG. But ISO seemed to become the standard eventually.
