comment Difference between RAM bandwidth and speed
@Ramhound, yea, not so much. Technically "bandwidth" refers to the width of the frequency spectrum of a signal. Colloquially it is used to refer to throughput, otherwise known as "speed".

comment Bash: if [ tar = error ]
You will have to explain what the script is supposed to do and what "doesn't work" means. I can't understand at all why you would want to print "success" if tar prints "/dev/null" and the other message otherwise.

comment Phantom Power on laptop
If you have a usb sound card that you can plug the mic into, then you can do so, and if not, then not. Phantom power is neither here nor there.

comment What are the differences between Linux and Windows .txt files (Unicode encoding)
@barlop, that is what I have been saying: it does not return any character. read() returns the number of bytes that it stored in your buffer. On EOF, it simply gives you zero bytes. That is the signal that you have reached the end of the file, and that there is nothing more to read.

comment What are the differences between Linux and Windows .txt files (Unicode encoding)
@barlop, the terminal translates the keystroke ( it is normally ctrl-d on unix systems ) into EOF, unless this control key has been disabled. The application reads an EOF rather than the actual key you hit. That is to say, read() returns zero bytes instead of any specific character.

comment Can't increase my partition size due to start
cylinder alignment has been obsolete since the late '90s: any concept of chs geometry is completely fabricated.

comment Oracle VM: “No space left on device” But Space Exists
Yep; you can't just slap in a larger disk: you have to resize the partitions/filesystems.

comment Laptop reporting wrong count of RAM slots?
You will have to check with the manufacturer. Either they can tell you where they are, or they will tell you there are only two ( in which case, they just screwed up and did not change the default description in the bios to say there are only 2 slots that they pinned out on the board ).

comment Why do laptop manufacturers turn off only the backlight not the whole LCD?
Simple.. it is the backlight that hogs most of the power; running the lcd itself takes hardly anything, so you would not gain much by shutting it off.

comment LD_LIBRARY and ldd: cannot open shared object file although it exists
Your LD_LIBRARY_PATH is not what daemons run by the system have. Are you manually running postgressql, or letting it be started by the system? If the latter, then it doesn't get the same LD_LIBRARY_PATH.

comment AES encryption with plain text key using bash openssl
You told openssl to use 256 bit encryption, but only gave it a 128 bit key. I'm guessing the online tool is only using 128 bit encryption, and so you need to do the same.

comment Can a 32 bit OS run in a 64 bit processor?
You have a few factual errors: 1) the itanium did not introduce variable length instructions ( every x86 has had them ); it added very long word instructions, which were capable of concurrently operating on multiple 64 bit quantities. 2) x86_64 did not just slap on more address lines; it also added a bunch of extra registers, and widened all of the registers ( and the ALUs that operate on them ) from 32 to 64 bits. Compare this to the 8086/8088, which added 4 more address lines and segment selector registers, but kept them all at 16 bits, like the 8080 before it.
