comment What is the name of the cable inside PC cases?
The reason they have 2 ground wires is that it allows using the same gauge of wire for all the connections; with only a single ground wire a thicker wire would be needed to avoid overload when both the +5 and +12v lines were fully loaded.

comment Can I repair a physically broken USB drive?
IF you don't have a computer with a sacrificial port; you can get a cheap USB hub for <$10 and to plug into that instead.

comment Excel VBA program only running at 25% speed
If you're concerned about run time, porting your computational logic into another platform would be a very good idea. I achieved an ~1000x speedup porting some very computationally intensive code from (Excel 03) VBA to C#: ~4 hours vs ~15 seconds. Same algorithm in both cases; and the VBA had already gotten a 5-10x speedup over the naive implementation by caching values to variables instead of reading the cell every time and disabling refreshing of the spreadsheet on screen every time a cell was changed during the computation.

comment Can I add RAM sticks from an old PC to improve the performance of the new one?
@AwalGarg there've been a lot more than 3 ram standards. Going backwards you've got DDR1, Rambus, SDR, EDO, FPM... and that's just the last 20 years and ignores ram used for uses other than PC main memory.

comment Swap partition size on a 64 GB RAM computer for memory-intensive work
+1 for the last paragraph. The 2x recommendation dates back to when most computers didn't have enough ram to avoid swapping in normal use. Subjectively, from using computers then, the 2x limit appears to've been selected as a number big enough that the computer will become unusably slow before running out of swap.

comment How do I Connect a 30yr-old Tandy 1400LT laptop to the internet?
@thkala it probably just means the computer has 768k total ram. Standard DOS programs were limited to 640k of ram, with the space between 640k and 1024k available for use by driver type programs (TSRs).

comment Does any mouse really have 11 buttons?
@AthomSfere action RPGs too. I bought one for playing Path of Exile and bound commands to 10 of the 12 side buttons; unfortunately it's a relatively short mouse and after a few nights of use I discovered the back 6 buttons required bending my thumb too sharply to use and was causing RSI type pain in my thumb.

comment Why are laptop screens sized the way they are?
@TheCleaner Since they've rounded all the cm sizes to integer values in that table (ex in the top row: 9cm 16:9 is listed as 8x4cm); I'm not sure it's safe to assume that the actual panel sizes are even numbers of centimeter in the diagonal.

comment Why do English characters require fewer bytes to represent than other alphabets?
The ա character is 2 bytes (0xD5A1) in the UTF-8 version of unicode; the extra character (whatever is is) is present in both files. marathon-studios.com/unicode/U0561/Armenian_Small_Letter_Ayb

comment Two identical external monitors, one through HDMI another VGA. Text on VGA looks blurry
@Craig yes. It was a DVI-I port on the monitor. And I discovered the problem when I noticed that one monitor didn't offer the same on screen menu as the second. For some unknown reason when I needed longer cables I bought DVI-I instead of the -D variant. The 2090 has one port of each type. necdisplay.com/p/desktop-monitors/lcd2090uxi-bk-1

comment Two identical external monitors, one through HDMI another VGA. Text on VGA looks blurry
@Craig I was using a pair of NEC 2090's (high end 1600x1200 LCD) side by side for almost 2 years before discovering that my computer/monitor had decided to use the analog link in the DVI-I cable for one of them instead of the digital link. NEC's top line of monitors have a very large price premium to cover using top quality parts everywhere. Even knowing one 2090 was on analog I couldn't see any quality difference between the two. For most consumer grade monitors the difference is much more visible. I have immediately noticed cases where 1 of 2 dell 1280x1024 monitors was analog.

comment What are these “notches” on the side of the PCI Express connector?
silkscreened on the board next to the lock is "core unlocker". My guess would be that it is either to try and use the 4th core on a 3 core cpu (AMD only) or to remove limits on how high the CPU can be overclocked (going from generally safe limits, to values that need sub-ambient cooling of the sort normally only used for competitive overclocking.) Unfortunately glare is obscuring most of the name on the board and Asus uses Formula branding in a number of high end models.
