comment Could exiting the media player without stopping/closing the file cause damage?
I'm not sure what you mean by "vestigial" - the stop button has a purpose of stopping playback while leaving the application open, and File/Close is the same as "simply exiting", and always has been.

comment Why am I able to execute a program that is not in my PATH environment variable?
@MarkHurd cmd (and CreateProcess) doesn't examine the App Paths registry entry, only ShellExecute [and therefore the Run dialog] does.

comment How can I remove a folder without a name in Win7?
It probably has a name using Unicode characters that don't show up in the chinese codepage. You could probably have deleted it from Explorer - or, selecting a truetype font and hitting "tab" from the command line to autocomplete [like "rmdir <tab>"]

comment Does a computer use fewer resources when programs are minimized?
An interactive program doesn't have to "recognize when it's minimized" to be using less CPU due to simply not having any keyboard/mouse window messages to respond to.

comment What did computers use for output before monitors?
My issue was with surfasb's claim that computers naturally had screen output and "printer drivers" are redirecting that output to the printer. (I suspect this is an incorrect oversimplification even for PCs, but that's another issue)

comment What did computers use for output before monitors?
@surfasb that's a PC-centric view. UNIX systems, on the other hand, used teletypewriters (a type of printer), and a modern system simulates one (well, more or less - what it actually simulates is a VT100, which is a type of keyboard-and-monitor device that replaced teletypes) on the screen.

comment What's the difference between the “Win-D” and “Win-M” shortcuts?
They're not invisible, they're behind the desktop [which is an actual window - the "real" desktop from the 3.1 era isn't normally visible].

comment Are rights 7110 equivalent to --S--S--s?
It'd actually be --s--s--T as formatted by ls. --S--S--s is nonsense (since the last should be t), and would be 7001 in any case.

comment Understanding Linux symlinks
The problem is more that it wouldn't allow you to put anything in your home directory [bashrc etc] that's not going in /var/www. This is twice as much of a problem if he needs sudo to access the www directory, since it would mean he doesn't have a home directory that he has access to at all.

comment Ctrl + Alt + Del with a mac keyboard
What Apple keyboard doesn't have a delete key? Anyway, try the numeric keypad (period/decimal with num lock off - if it doesn't have num lock, try and see if one of the 'non-PC' keys on the numeric keypad, clear and =, are mapped to numlock by default.)

comment ls -d is not displaying directories. Is there a way to get ls to only display directories instead of files and directories
Right, but there's no logical reason ls can't have an option which will filter out items that were passed in as arguments. The fact that "wildcard expansion is divorced from entry type checking" is irrelevant, since this has nothing at all to do with wildcard expansion - only entry type checking, which there is no reason it cannot be done entirely within ls. If ls --color can shade them blue, ls -F can put a / after them, and ls -l can put a 'd' in the mode, then some other hypothetical option could omit them. That such an option does not exist doesn't mean it "cannot".

comment ls -d is not displaying directories. Is there a way to get ls to only display directories instead of files and directories
"there cannot be such an option" - that's a rather strong statement - the implementation of such an option is obvious: see a non-directory argument and ignore it. What can't be implemented is the equivalent of dir /s *.txt [without resorting to quoting wildcards as for find]

comment What is /usr/bin/[ and how do I use it?
It's required because if it were optional the syntax would be ambiguous in certain situations.

comment Can I remove a RAR file's (known) password without recompressing the archive?
No, logically, it should be possible to decrypt the data without decompressing it, because it's encrypted compressed data, not compressed encrypted data. (the latter is fundamentally impossible, due to entropy increases from encryption). It's just an obscure enough thing to want to do that it's omitted.

comment How far will you get with an 'rm -rf /' command?
The standard specifies that rm is not allowed to continue if an argument has the string "." or ".." as the basename component. You cannot remove /foo/.. even if you're not in /foo. It does not specify that you're not allowed to remove the current directory (e.g. rm -r `pwd`) or the parent of the current directory.

comment How far will you get with an 'rm -rf /' command?
"pointing out that if one attempts to remove "/" recursively, one will ultimately attempt to remove ".." and ".", and that all we are doing is allowing rm to pre-determine this heuristically. Amazingly, they bought that! " - er, wouldn't that disallow removing any directory? The actual spec only disallows .. and . in the actual command-line arguments, it doesn't say anything about what you "ultimately attempt to remove"

comment Why can't I email myself at: MyEmail@74.125.235.55?
@[ip] is a special syntax in the RFC that is defined as bypassing MX lookup.
