comment How many times can I format a hard disk?
A modern voice coil mechanical drive is not going to lose calibration by seeking. Old stepper motor drives did suffer from drift though.

comment Why is it not recommended to shut down a computer “brutally” (power switch)?
Back when stepper motor drives ruled, one would (ideally) park the hard drive (placing the heads over a non-writeable cylinder) before shutting down (with physical power switch). Park software would also clear the write caches. Servo drives eliminated that parking need as they added a retract mechanism when power is lost, so you paused a few seconds before power off. The heads will retract to the parking cylinder before the air cushion allows the heads to settle to the surface. It was years after that when we actually got a "soft" power off buttons. Historically it was always a hard power off.

comment “Turn off router for 10 seconds” - Quantifiable?
On the ASUS board, that's why those boards usually have a jumper you can short (once battery is safely removed) to drain the stored power. It's basically shorting the system to force an immediate dissipation.

nohup sends the output to a file where it can be processed.

comment How Is It Possible To Send Email Under Our Domain Name
SPF seems to be pretty well adopted at this point (it's been around for a long time, adoption was a slow process). DKIM seems to be more hit or miss.

comment Installing VirtualBox Guest Additions on Windows 10?
Works fine for me without additions. Definitely some under the hood changes on 10. I'm having problems installing an application that made the transition from Vista to 7 to 8 without any problems.

comment How can I find out the password complexity policy?
Not always so theoretical, having been trying to help an end user with this exact problem when the sysadmin was on vacation... It's a pretty big design flaw that Windows doesn't tell the user what the complexity requirements are during the password change process.

comment How do I install my SSL certificate?
Hmmm, Magento has a special "enable SSL" option in the GUI though. Am I supposed to use that or not? That's why I thought there was something specific to Magento in the configuration and that it's not a straight up Apache config.

comment How to determine what app is generating network traffic?
Seems popular these days to make apps that auto-update/get virus signatures by opening multiple connections that blow away the usefulness of network connections for other people. "Check for updates" seems to be a thing of the past unfortunately. The people writing these apps must only test from their local Gib/s network. Very annoying.

comment How do I disable an Outlook 2013 add-in without starting Outlook?
I've found that if you wait awhile, it will figure out that they're not responding even in user mode at startup.

comment How to properly use USB sticks on Linux and Windows machines?
I've seen the exact same problem on network shares too between Windows and Linux. I'll write a file from one OS and the other won't see it sometimes.

comment Sudden hard drive failures
Bad luck? I had a client that lost 3 hard drives (all different models, and at least 2 different makes IIRC) on the same machine in about 2 years. 4th drive has been going for years now.

comment How can I make Skype love my X230's microphone?
Update, the latest version of the drivers have several options that may need to be twiddled based on software in use. On my system Skype wants a certain set of them, and Bria a totally different set.

comment Why's Windows keep losing my storage device on reboot?
Also seems to work fine when the HDC is in a 4x/16x slot too. Just those pesky 1x slots that cause the problems.

comment Why's Windows keep losing my storage device on reboot?
This does not work. It also does a fast reboot (no self-test run/no option ROMs loaded).

comment Is it okay for a new laptop battery to report 90% capacity?
Yes, in order to extend the useful lifetime of the battery, it may only charge into the 90% charged range.

comment MBR/Boot sector wiping virus/trojan?
I didn't bother to repair the MBR. He only uses it for web surfing and checking e-mail, so data loss isn't a concern. I wiped the drive with the Adaptec firmware then built new partitions and reinstalled. I've never heard of "DropMyRights" before. I'll have to go check it out.

comment Change /etc/, /var/ permissions to 777
I was operating under the belief that root wouldn't login from console due to /etc/passwd being 777, rather than it being disabled. I'm not familiar with CentOS specifically anymore.

comment Change /etc/, /var/ permissions to 777
From the original question, I don't believe that console access will work either.

comment Latency of CPU instructions on x86 and x64 processors
One cycle, except when it's "free" (in parallel when pipelines line up correctly) or takes longer due to a cache miss. :-)
