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.

comment Are super computers made with just cache technology?
top500.org maintains a list so you can see what makes a "supercomputer" by their particular standards. There are a lot of big clusters of fairly work-a-day machines plus some special purpose architectures.

comment Lightweight text-editor with two code panels
Eight Megabytes And Constantly Swapping was a heavy editor. It really was, and it's not a flyweight even now; but it just doesn't sit on large fractions of a memory anymore.

comment Which ethernet expansion card is compatible with an Apple PowerBook 5300c?
BTW--Apple was making 7.5.5 available for free for a long time, and it really is more stable than the earlier 7.5 versions.

comment How to open emacs in its own window
@BennyInc: Note that xemacs is a different program from GNU emacs running in X. There was a fork owning to deep disagreements about the proper direction of emacs development. The two branches have developed similar capabilities but the remain distinct.

comment Edit one file in two different buffers in emacs
Yikes! Shouldn't you include keyboard navigation between frames? C-x o runs other-window and cycles through the visible "windows" in each "frame". (Using the emacs configuration where window manager windows are called frames, and the separate panels inside them are called windows (I know, I know, but I'm not responsible for it).)

comment Why is the dreadful 'rm -rf /' even allowed?
I imagine that there is a philosophical bias against it. After all, once you get into the protecting users from themselves business, where should you stop?

comment Linux (All distributions) completely freeze
Hardware failure is not excluded just because Windows works. That merely means the failure is in some hardware feature that Windows does not use or that windows can detect and work around.

comment spectrum analyzer that shows 'live' input from the microphone
If you really want spectrum analysis then there is a trade-off between using a large window for the FFT (which gets precision and wide band at the cost of delay) and responsiveness.

comment Asterisks on Password for Bash Shell (or ssh?)
@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.

Or ls -l if your shell is configured the usual way.
