comment How does wake-on-lan works?
I've looked into WOL myself before and it's far less useful than one would expect. The "same broadcast domain" requirement makes it inconvenient in many circumstances (like all of them I find myself wanting WOL for).

comment How to limit CPU consumtion of a process group with standard GNU/Linux tools?
Doesn't seem like an esoteric scenario to me as I encounter it frequently. Users wanting to run larger processing tasks, but not allow them to knock down the rest of the machine at the same time. A % of CPU limit would be ideal.

comment How to diagnose slow (only for awhile after start) Windows 7 machine?
It can take 30 seconds for the system to respond to input, but the thrashing was going on for 30 minutes...

comment How to diagnose slow (only for awhile after start) Windows 7 machine?
I haven't had time to capture the boot trace yet (SDK download takes awhile on DSL), but I ran across a Google article that suggested disabling superfetch. That made a tremendous improvement in responsiveness during as well as duration of disk thrashing.

comment How to diagnose slow (only for awhile after start) Windows 7 machine?
@whs - I have an even slower, single core Atom machine here too, with the same RAM and also a slow laptop drive that does not exhibit the same issue. It settles in within a minute or 2 of booting. There's no reason for the faster machine to require over 30 minutes. Something abnormal is going on.

comment How to diagnose slow (only for awhile after start) Windows 7 machine?
I think you missed the point. It performs acceptably when running applications that consume RAM, etc after the initial tie-up right after boot. It's no screamer, but is fine except for this disk thrashing right after boot (even with no applications running). After done thrashing, it runs perfectly fine even with OpenOffice, Chrome, and an IDE open at the same time (and they startup and load just fine too as long as I don't do it until the initial disk thrash is done).

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.

comment PuTTY or OTHER - Keep executing command even after exiting PuTTY
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.
