Experimental nuclear and particle physicist. These days I'm teaching, but I've spent a lot of time on nucleon structure in fixed target electron scattering and neutrino oscillations using reactors and beam sources.

@grawity: As that is directly responsive to one part of the question you should probably make it an answer.

comment Asterisks on Password for Bash Shell (or ssh?)
A quick troll through the man pages stty (1), tty (4), getpass (3), and readpassphrase (3) seems to confirm this.

comment What is the max. capacity of RAM in 32-bit machine? Why it is not 16GB?
The confusion here is between the size of the processor word (32 bits in this case) and the size of the addressable memory unit (in the case of current general purpose machines that is 1 byte = 8 bits). So yes, the processor can load four addressable memory units at a time.

comment Shell starts in incorrect directory in OS X Lion Terminal
On a vanilla unix system I would be instantly suspicious that you were logging in as root. I've never tried that on a Mac OS box, but if you I would advise you to quit doing so.

comment Is storage hierarchy the path of data flow?
This covers it all pretty well, but I will note that there have been strict load-store architectures in the past which required to be explicitly loaded into a register before it could be acted on. As far as I know those are few and far between these days. I suspect that all full service OSes restrict direct to secondary access, but we used to do that on the Apple ][+ back in the day.

comment Unix command history — finding a command fast
Note that this is a function of your shell (bash, tcsh, zsh, fish ...) not of "unix" in some general sense. If you don't have a clue what I'm talking the bash related answer below will probably work for you. Or try printenv SHELL.

comment Are there non-GPL alternatives to Busybox?
Busybox isn't a problem unless you want to (1) modify it and (2) not give the changes back. If busybox meets your needs right now (or if you are willing to see any changes put back into the commons), using it doesn't expose you to any risk at all. The lawsuits involved entities in breach of the license.
