comment Is liquid cooling necessary for high CPU performance over extended periods?
FYI newer versions of Prime95 use FMA instructions in stress testing (and presumably normal prime hunting too); making it function more like a power virus/short term burn test tool than the long term stress tester that it historically was. For my 4790k, IIRC, they pushed it ~20W above TDP at stock speeds/clocks; and 15C above the thermal load of an older non-FMA version. (I was running watercooled so my thermals were reasonable; I wouldn't be so confident about the stock Intel cooler doing well.)

comment When do I need a pure sine wave UPS?
@WarrenYoung One review site I've seen linked to occasionally did do active PFC/modified sine UPS testing. IIRC the normal result was that the maximum load the PSU could handle was less than the PSU or UPS should've been able to do. I don't recall if it was the PSU, the UPS, or both that was being de-rated; if it was the UPS you might be able to get that PC through an outage by using a more powerful backup for it. I'd probably go with just replacing the PC's power supply rather than deal with any potential headaches down the line from a non-standard config through.

comment How do I tell if my Memory is ECC or Non-ECC?
@DavidGrinberg it means your memory doesn't have ECC. Outside of servers and some high end work stations very few computers use it.

@kristianp The 2nd command had two typos in it, should've been: wmic memphysical get memoryerrorcorrection (worked for me in 8.1)

comment Fully expand email thread in outlook conversation view with single key stroke
@sunk818: I don't think what I'm seeing in 2010 could be called a regression bug. From descriptions of what's going on MS decided to be "clever" and only show an abbreviated subset of messages containing unique text. Any messages that were fully quoted in a reply are initially hidden. If that's changed in 2013, I'd call it a user revolt instead. I have access to MS HUP via my employer, so I can get a copy of 2013 cheaply. I'm not thrilled by the styling changes; but a working tree view combined with all day meetings showing on the appointment list (07 doesn't) is worth it I guess.

comment “How do you want to open this file?” dialog appearing at random after upgrading to Windows 8/8.1
@DavidPostill Unfortunately not. Clicking any other window dismisses the How... window. I tried taping the mouse button down with the intent of removing the tape to release it over the How... window once it appeared, but the cursor was reset to the arrow when the How.. windows appeared.

comment “How do you want to open this file?” dialog appearing at random after upgrading to Windows 8/8.1
@Ramhound If I can't figure out where this is coming from, I might as well nuke it, do a completely clean install and destroy all the random crud that's accumulated over the years. Useful data's easy to restore from backup, it's the 10 zillion desktop applications that would need reinstalled that made porting my existing Win7 install to new hardware and upgrading to win 8 worth the effort.

@Xavierjazz I might have 10 years, and innumerable regurgitations of it from one click bait content farm to the next ago...

comment What are the license(s) of the Linux man pages?
Debian's reasons for not using GFDL were an eye opener. Did the FSF ever respond to them?

comment What is the 6-pin power connector on an HP ProDesk?
@IsmaelMiguel the 6pin connector is designed and sold (licensed?) by a company called Molex (as the 4/8 pin, 20/24 pin, and 4 pin drive/fan connectors); they only specify the physical connector layout. What the wires built into the connectors carry is up to the company implementing them.

comment What is the 6-pin power connector on an HP ProDesk?
That test report does give some insight into what the HP PSU is doing. All of the tests measured 0W of 3.3/5V power; it only provides +12V and -12V rails. The DC-DC converters needed to supply the 3.3/5V power needed to run drives and misc devices on the board itself are on the board instead of in the PSU as standard.

comment “Turn off router for 10 seconds” - Quantifiable?
Anecdotally, several 30+ minute outages I've had over the last decade did end within a minute of my giving my cable modem a 2+ minute off period. OTOH the other ~80% of the time I tried doing so it didn't help.

comment Why are my games slower on battery power, even with the power plan set to High Performance?
@misha256 You get 2 or 3 of the following: 1) the cheap battery pack that's partially fully of air. 2) The normal battery pack that fills the standard size enclosure. 3) The oversize battery pack that extends outside the normal limits by either bulging out below or behind the main body of the laptop.

comment What is a PCI-Express Lane?
Single port gigabit networking cards don't need multiple lanes. Even a PCIe 1.0 lane offers 250MBps = 2000Gbps of bandwidth; which is enough to allow for 50% overhead losses while still being able to keep a gigabit port saturated. Multiport gigabit cards can need more than one lane; but if that's what you were referring to you should be more specific since they're generally not something seen outside of a server room.

comment What are the three buttons above touchpad in the Dell Latitude E6520 laptop?
@Kos you need to buy your next Dell from the Small Business section of the website. The pointy sticks are limited to (some) Latitude and Precision models. Alternately, some Thinkpads offer them; and at one point so did some HP business class models (not sure if they still do or not).

comment How can I tell which version of Windows was installed before update?
The error reporting log appears to get truncated as well. My oldest event there is from about 10 months ago, on an install that's several years old.

comment Why are Ethernet/MAC addresses needed?
@user2449761 All packets only go to all computers if you're using ancient networking hardware that has hubs instead of switches. Hubs were originally an option for cost reasons; but now that switches are cheap nobody uses them anymore.

comment Can a 7 days full 100% CPU load “burn-in” / “stress test” damage a modern notebook?
As a counter example, I ran a cheap 15" Acer laptop at near 100% load from 2006-2013 (distributed computing); and aside from a fan replacement at the ~5 year mark it was still working well when I gave it to a family member who needed an emergency replacement computer. AFAIK it's still running well today.

comment Can I add another stick of 2 GB to a 32 bit Windows Starter system?
It's not quite useless. While the OS is limiting you to 2gb of usable ram; going from single to dual channel mode will double ram bandwidth and should give a modest improvement in real world speed when doing anything computationally intensive.

comment What is the relationship between Unix, Linux, Ubuntu, Debian and Android?
At the same time, any non-trivial distro these days is going to include lots of stuff that is neither part of GNU nor the Linux kernel itself. Does anyone really want to chain all of those into a name less practical than the full titles of reigning monarchs?
