Actually, installing Linux from a CD = cost of Linux CD + cost of CDROM drive.

This could end up being anywhere from $250 to $500.

The cost of Linux on floppies is whatever your employer/school pays for
net access plus whatever they paid you in terms of lost productivity.

Linux will not run "most if not all SCO binaries".

Linux will not produce viable SCO binaries.

Like it or not, SCO is the biggest UNIX platform.

SCO is more stable than Linux.

SCO has MPX.

For someone who wants to hack around with an OS, Linux is obviously
better than SCO.

For someone who wants to make money selling software packages, SCO is
obviously better than Linux.

Hello linux-world !

This is not a special linux-problem, but I think someone out
there in linux world will know the answer !

The problem :

Some weeks ago I saw a shellscript for sh with pointer in it.
It looked like this :

TEXTVARIABLE="Some Text"
POINTER=..? some syntax for pointing on TEXTVARIABLE ?...
echo POINTER  # prints "Some Text"
TEXTVARIABLE="Other Text"
echo POINTER  # prints "Other Text"

Could someone mail me the solution ?

Subject line says it, basically.  Awkcc is an AT&T-proprietary 
program to translate awk scripts into compiled C code.  The 
compiled C code supposedly runs an order of magnitude faster 
than the awk script.  While I have a copy of awkcc source, I 
haven't been able to get it to compile successfully on my linux 
system, and I do not have the time or inclination to track down 
and fix the reported errors.  So, does any one know where I
can find a version of awkcc that has been modified to work
with Linux 1.0?  I am willing to pay a reasonable sum for
this software.

        Sharing data, IMHO is not necessarily a good thing. I would
        not want several running tasks/threads sharing the same data
        due to the opportunity for collisions/race-conditions etc...
        Debugging your new system, given a fair amount of complexity,
        could become a tremendous issue. 

        Again, threads is not the only way to solve this problem. Under
        Linux you will be able to use the "select()" call to allow
        your "single" task to listen on numerous ports. i.e. no need
        to poll or round robin and thus waste CPU cycles. Let the OS
        do it for you!!

        BTW, if maintaining particular "framerate?" is a major issue
        then maybe a "real-time" OS would be better suited for your
        system. I believe QNX has real time extensions as does SVR4.2

        Why re-create the wheel?? If this type of thing is already
        available use it, then spend the time saved on the important
        features of your new system.

        One last word... Consider porting issues. If you lock your
        system into a particular vendors thread package or recreate
        multi-user accounting as part of your system, will you ever be
        able to port your system to another environment??? If you 
        address these items up front you will be able to port your
        system to other vendors offerings.

required, but not sufficient - a unique IP address is required, so that
there's no confusion between machines - but any machine you talk to needs
to know how to send data back to you. And as far as I know, that means that
every machine along the route needs a suitably set up routing table - usually,
"route messages for this subnet this way, route messages for this machine here,
and if you don't know, send it there".  So just getting your own network
address isn't sufficient to talk to external machines from your net.

True; on the other hand, the NIC application forms seem to regard class C
as the smallest allocation chunk at the moment, so presumably this isn't yet
a significant problem. On the gripping hand, with a maximum of 16.7M class Cs,
it might eventually become one - but I doubt whether linux users are going to
take more than a minute part of that :-).  And no doubt we'd probably see class
D addresses introduced (or longer addresses) if it ever does become a problem.

Exactly; your setup works because other machines know how to route to the
class B net. (Is that what you meant by 'valid'?). Unless you're using part
of an existing network address space, things start getting messy :-) and
complicated. Simpler to pay your service provider and let them sort it out,
especially since you'll probably need to pay them for it anyway :-)

Hello netters, 
        I am trying to create a new keymap ( for some language or other )
THe problem I am having is getting the damn keys to send the ASCII code I want
For example, I want the ALTGR-A key combination to return an ASCII 0x80.
so I go into the keymap and plug
altgr keycode 30 = 0x080
I load the keymap,press ALTGR-A and get 0xe1 which is 0x61 (small case 'a' ?)
with the high bit turned on.
        Can some kind soul e-mail me an expalnation please? If I cannot 
get it to work like this I am gonna rewrite the keyboard interrupt handler

And that was a promise :-)

Subject: x Windows errors
From: michael.houle@freddy.supernet.ab.ca (Michael Houle)
Date: Fri,  1 Jul 94 21:50:00 -0700

Hello Linux Users !

I was wondering if there was anyone who had a few answers for me. 

I just installed linux. Love it. Finally, a decent OS. 

Does anyone know about Xserver errors ? Everytime I exit fvwm, or any other
windows system,
I get an error message. Something like this:

Broken pipe on display 0

Waiting for Xserver to shut down. failed after 678 retry's. 

Am i missing something in my xconfig ?

Also, I am using a 1024 by 768 resolution video mode. When i use vi or use a
scrollbar on any of 
my windows, The edge of the window (panel) shakes a bit. It doesn't actually
move but gets distorted.
Almost like static. Does this mean I am using the wrong clock speeds ? I
don't think it would be my video
card cuz I don't get these problems with Microsoft windows or any other high
resolution package.

Any assistance to these problems would be greatly appreciated.

Later.

 The 2.0CSD was free, the 2.1beta was free, the 2.1 CSD was free.  I only
paid $60 for my 2.1 floppies, after you account for the IBM $30 rebate.

 Well free in the same way that Linux is free.  It actually probably costs
me on the neighborhood of $50 in lost time ftping 30 disks off the internet,
and that is only because I am fortunate to have internet access as part of
my job.

 The thing that this shendrix guy doesn't seem to understand is that he only
spent like $60-100 for OS/2 2.0, which just barely covered the production
costs.  Now he is demanding that they send him another $60 in disks and
manuals for free?  I don't think so.

 I'm sorry, I don't understand his reasoning.  $60 was a fair price for the
2.1 upgrade, and the time spent downloading the 2.1 CSD was worth every cent
as well.

 Sometimes people at .edu sites become sheltered from real world costs.  It
is sad, because colleges are supposed to be preparing people for the world,
not hiding the world from them. :(

What's the trouble with that 540MB drives? I personally share a 540MB

The only thing you must not do is making the linux boot partition larger than
