His reply was quite thorough, I will concede that. But he simply told you
that you were phrasing your question improperly. Not to mention he didn't
answer it with much details about whatever little standards used , if any
(which you claim to really have wanted as the answer).He explicitly said "I
won't go into details of what constitutes military specifications and how
they are framed. I will also not discuss whether the Indian Military has got
any such specifications regarding software". Heaven only knows how you got
the "correct answer" when the other person is actually and explicitly
telling you he won't give you the details of the answer at all.
Question is that if you do not know the answer, and you have been asking the
wrong questions to begin with, how do you know what is the "right" or
"wrong" answer ? Especially in this partcular context one could only say
that his reply sounded like the first "complete/adequate" answer. Phrasing
is all important. Lacking that you will only serve to irk those who are only
trying to help you.

Because A) you never specified which military. B) Military grade software
for what fields/purpose ? C) you were informed that in USA it was done via a
standard certification and on adhoc basis in here and most of the other
countries("top brass" as you phased it). There are little or no standards in
place here yet, the last time I checked(and having worked with the armed
forced maintaining their servers, I did ask them about it once). I provided
you with name of the standards used in US "Some of the standards included in
COE are POSIX (1003.1 & 1003.2), X11, Motif, CDE, TCP/IP"
Usually the armed forces here do not give out orders to the tune of those
placed by Us DoD, and hence cannot really force any of proprietary OS
developers(Novell/Microsoft/Sun) to modify their products to comply with
their guidelines(i.e. DoD insisting that the OS should be POSIX compliant).
As a "relatively smaller"(relatively only) buyer they simply have to choose
amongst what is available or try and roll their own. They can however insist
in the case of application development orders that "RDBMS application must
run on oracle backend or be compliant to such and such standard" but there
is no fixed policy on it. But quite frequently this will be done "in-house",
I'd imagine, for security reasons.
Take your second query for example : "Can anyone point me to fault tolerance
components of Linux kernel, if any exists. Or alternatively tell me how
faults are handled in linux kernel."
What kind of faults ? harddisk ? there is software RAID support in linux if
that is what you want to know. But that is the filesystem rather. The other
faults can be in memory, processor, network. Well in Linux kernel, illegal
access of kernel memory space by a user process will usually crash the user
process. Kernel memory remains intact. Period. If the RAM chip itself is
faulty it is usually the bios that informs you during booting(beep codes
remember?). Network faults ? You probably know the answer. Processor failure
? Am not sure about the standard kernel but I do recall NEC UK managing that
with a modified kernel. Then there is also clustering.
So basically what exactly are you asking ? did you make a little effort to
visit http://www.google.com ? Wouldn't you get an answer more easily and
authoritatively and on the linux-kernel list
(http://vger.kernel.org/vger-lists.html#linux-kernel)?
Before posting a problem, atleast try to show you made an effort solving it
yourself.
" Also, can anyone tell me how much immune is Linux
Kernel to noises of environment.(how noises are
handled in linux system)."
I have no idea what you are talking about here. What kind of noises ? "data
noises" ? What kind of data ? Isn't that rather upto the application in
question which is accessing the said data ? Why would kernel care ? Or do
you mean actual sounds ? What on earth would linux kernel have to do with
detection of whether you are having sonic boom explosions next to your
building ?
See? Totally ambiguous. Try and phrase your questions better.
