magically going to come up with 20,000 (guess) people to support
LINUX within 20 years? Maybe in INDIA (or China) not in most other
parts of the world. I won't go into the issues of the US government
running their super TS applications on code that was written in a
foreign country. That leaves the US government having to write and
design their own OS , boy are we in trouble.

You are full of it. Linux is written in C, not COBOL or Assembler.
Also,
there is not a different version of Linux for mainframes, the vast
majority
of the code is the same on all platforms. What is difference is memory
management and of course I/O. This is done mostly through IFDEF
statements
in the Linux kernel C code. And the System z "changes" are
integrated into
the mainstream Linux code, not something kept separate by IBM.
Go back and read what I was saying it was being sarcastic turning the
hose back on (directed at IBM) well lets see.. c is written in ....
guess what.... again who is write system level C ? Its one thing to
write application code in C (or C++) an entirely different item to
write system level C. Probably a lot of the operating system level
items will have to be done by C generating assembler instructions you
still will need to know ASSEMBLER.
Also, Linux is the NUMBER TWO operating system in the world now in
terms of
units (more than all other UNIX variants combined). It is the fastest
growing operating system and will continue to grow.
So? all that says that servers are cheap.
There have been some other comments in this thread about the
entertainment
system on A380s (and other planes) running on Linux. Well you
should be
aware that ALL the systems on the international space station are
running on
Linux.
No wonder we have spy satellites crashing. Mind you are the ones you
are talking about mission critical? Not just entertainment system
runners? I remember seeing MS running similar configs and also have
seen a BSOD on airplane screens. Management is just looking for
cheaper not the best an they get what they pay for.
I could respond to your paranoia about code written in a 'foreign
country',
but do you really think anyone develops software exclusively in the
US any
more? IBM, Microsoft, et all have development labs all over the
world. The
internet has erased the boundaries for software development (and a
lot more)
and it will continue to do so.
Well I am well aware that MS develops code around the world does it
make it better? Nope in fact its one of the worst OS's around. Talk
to any IT professional and have them compare MS to say UNIX
(assuming) you are talking to real professional you will get a finger
pointed down at MS. The issue that MS is afraid to compare is
security. Security (and integrity) has *NEVER* been part of the an MS
design point. Unix (not that UNIX is great mind you) but it has a
proven track record with security. IBM's MVS at least has a security
designation can any of MS's OS say the same ? Which begs the point
does LINUX have a security rating?
Linux will be around long after you are dust!
It depends as I am planning on being cremated so it may be sooner.
In any case LINUX will have to grow into another MVS before it comes
close to that. People are taking DUMB pills or is the education
system can't educate because the government keeps taking money away
to pay for tax breaks to the corporate world or is it .... never
mind I am sure you will find an excuse that its not my problem.
