comment Is it easier to install Ubuntu on a Windows 10 machine or Windows 10 on a laptop running Ubuntu
@Kevin Historically similar issues have existed with Windows multi-boot where older versions of Windows didn't know how to boot newer ones; but still installed their boot loader. The simplest way to avoid problems was to install starting with the oldest version of Windows and continuing to the newest. It's probably been close to a decade since I had multiple versions of Windows installed on a single PC, so I'm not sure if this is still an issue.

comment What is the memory requirement for Windows 10?
@Nye IT came with Win7 so it's almost certainly several years old. OTOH budget Windows tablets are shipping with 1GB of ram today.

comment UPS Do not get charged
Additional Warning/Note: If you do buy generic batteries, make sure you're getting what you think you are. My experience with getting new batteries for several 1300VA UPSes (multiple brands) is that there are plenty of un-ethical resellers who will list batteries with significantly smaller capacities (amp hours) than the OEM ones for use with larger UPSes. Presumably they'd work; but you'd end up with only the backup capacity of a 1000VA UPS instead of a 1300/1500VA model. Equivalent sized generic batteries were never more than a 5-10% cheaper than an OEM replacement.

comment Does a USB 3.0 connection require a USB 3.0 cord?
For completeness, it's worth mentioning that 10GB USB3.1 ports (twice as fast as the 3.0 standard) are commonly a lighter shade of blue. I don't know if this is an official recommendation or not; but has held with most of the 3.1 board prototypes I've seen so far.

comment Excel Run Length Encoding
I accepted this morning after confirming it worked on the production spreadsheet (needed to make sure it didn't need tweaking to play nice with everything else that one was doing.) I had to use the formulas: Filters don't update every time calls to random regenerated the bit sequence I was using as input and changed the rows that needed filtered as a result.

comment Excel Run Length Encoding
If it's not obvious to anyone else reading this answer; if you need more than 100 data points the column E/F formulas will need edited to take a larger input range.

comment Excel Run Length Encoding
I might be able to use a filter that excludes blank cells in place of the formula in the last two columns. Depends on how nicely it plays with downstream logic in the sheet on Monday morning.

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)
