comment How can my computer use 300% PC processing power?
@Vasfed I have no idea where you are getting this information from. This is a concept that has existed in Unix systems since the early 1980s, and including processes waiting for I/O in it would be insane.

comment How can my computer use 300% PC processing power?
@Vasfed The state being measured, "ready for execution" means waiting for CPU - an I/O wait doesn't count for it. All processes are waiting for something (except the one, at most per cpu core, that's currently running), after all.

comment Is there any danger when connecting a USB Y cable?
Couldn't the cable incorporate diodes to prevent backfeed?

comment Is there any danger when connecting a USB Y cable?
@MonkeyZeus Typically, the cord to the second connector (it's not really a "Y" in the conventional sense, the extra one is actually on a separate wire off of the first USB-A connector) only has the power wires, no data wires. There are even USB 3 versions where only the main one is a USB 3 plug.

comment Why are pixels square?
"""TVs had to render this data using physical phosphors, with a grid to divide them into pixels.""" - was this true of Black & White TV? My understanding was that discrete "physical phosphors" (which still never corresponded to any pixel-like item in the data stream) came with color TV, and that monochrome CRTs simply have a continuous coating of phosphor-stuff.

comment What key on a Mac keyboard corresponds to the ⇥ symbol?
Generally even though they're not labeled Mac users are expected to know the key symbols (they appear in e.g. menu shortcut labels even in the US, and on the on-screen keyboard) - even oddball ones like ⎋.

comment How and why is this string of text a fork bomb?
@MathematicalOrchid It actually takes nontrivial effort to cause backquoted stuff in user input to a shell script to get executed. And if you're constructing a shell script from user input you should know better than to put it in double quotes.

comment Why does 1366x768 resolution exist?
Before asking this question, did you do the math to consider that 683:384 is ~16.008:9, so not such a "wild" break after all? Certainly not nearly as much so as 1280x800's 16:10.

It also makes it easy to pillarbox 4:3 applications designed to run well at 1024x768.

comment Get rid of all ##### errors at once in excel
Alt H, O, I is the new access key for this... it seems a bit slower though as for me it takes a few seconds for office to draw the shortcut keys (which it doesn't bother with for the old keys).

comment Is typing %^ into cmd.exe a Windows easter egg?
@AlecTeal Yes, but to do that I have to keep putting ^ at the end of each line. If I type something (with no ^) to the first More? prompt, it executes immediately, but if I just enter, it prompts More? again. EDIT: I've done some further testing with echo which reveals that entering a blank line at the More? prompt puts a literal CR/LF in the command line. Don't know why I didn't run into that yesterday.

There's no guarantee that this executes pdfunite only once

Why does it prompt More? a second time if you don't put anything in response to the first one?

comment How to find Mac Code from serial number of Lenovo G50-70 I3
@vnodkumar1987 The ISP likely only has the MAC address of the user's router - i.e. the device that they actually use to connect to the ISP's network.

comment When do I need a pure sine wave UPS?
Speaking of monitors, I wouldn't power a CRT off of it either. Probably best to be careful about monitors in general.
