4Dwm runs into a bug in X11R4 Xt and xlib.
The simple work-around is to get rid of the "kill" feedback.
In   /usr/lib/X11/app-defaults/4DWm   (since you want to change 
it for everyone)  change the line:

        *showFeedback:                  behavior restart quit kill
to
        *showFeedback:                  behavior restart quit

SGI is now shipping a product called Impressario which does this for
HP DeskJet 500C printers.  It supports SGI Image, text, and Color
PostScript to the printer as well.  DeskJets and PaintJets aren't the
same, though.

I recommend the parallel port, there's fewer configurations to worry
about and its a LOT faster.

Check out Impressario, it may well be worth a little $$ (and less time
spent) to add Color PostScript capability to these printers.  You'll
still have to write the converter from generic bitmap to printer
(PCL2??) format, but that's all you'll need to do.

We have recently purchased a few SGI machines. According to the SGI people

  Take a look at the Panasonic EPL-8543.  It is not dye sublimation,
but it does a pretty good job with 4096 colors per pixel at 203
DPI.  It is substantially less expensive to purchase and to run than
a dye sublimation printer.  We connected ours to the parallel port
on a 4D/30 and wrote some simple software to dither RGB bitmaps to
print them on it.  We use GhostScript to print PostScript.

Subject: *.rgb -> TIFF -> Mac Pagemaker
Date: 28 Aug 92 22:45:18 GMT

Hello!

I'm using the 'totiff' utility from the NASA iris site @ Langley to 
convert *.rgb to TIFF. Then it is transported to Mac for incorporation
into a Pagemaker document.

Problem a):  Pagemaker dislikes this kind of TIFF, it puts some
             horizontal running black lines into the picture
             in a random way.
 
             Any other Mac Programm (e.g. Adobe Illustrator) has
             no trouble with it.

             Does anyone know about this? Unfortunately I must use
             Pagemaker.

Problem b):  The printing service has recommended to use a 4-color
             TIFF, what means that black is stored into a own
             layer. This would stop the printing machine from
             mixing up black out of red, green & blue.
             (And results into a more clear print)

             Does there exist a utility for this "4 color TIFF"?

I assume you mean the math library, since math functions in C require
linking with libmath.a, and that you mean the hypotenuse in a right-angled
triangle.  Some 6 years ago we were doing some programming on a 3130,
and we discovered that this particular math function was broken; I
believe that this turned out to be an acknowledged bug in the code for
this function.  (I don't recall if the results were _always_ wrong, or
only under some circumstances.)  Could it be that is has never been fixed?

Subject: GL puzzle: zbuffer madness
Keywords:  zbuffer, swapbuffers
Organization: University of Toronto, Engineering Computing Facility
Date: Sat, 29 Aug 1992 16:27:26 GMT

Here is a GL puzzle that really puzzles us (days of debugging but
still little clue what happens).  We hypothesise that, zbuffering
does not work well if a drawing continue after a buffer swapping.
But the manual does not say anything about this.  Hope you GL
expert can shine some light on this:

When we use this sequence, it works (I'll give criterion later):
	while (1) {
		clear();
		zclear();
		for (i=0;i<10;i++)
			draw_thousand_labels (i, eye);
		swapbuffers();
		eye = !eye;
	}
Now we use this sequence, it does not work (again, see the criterion later)
	while (1) {
		clear();
		zclear();
		for (i=0;i<10;i++) {
			draw_thousand_labels (i, eye);
			eye = !eye;
			swapbuffers();
			draw_thousand_labels (i, eye);
			eye = !eye;
			swapbuffers();
		}
	}
(The reason of trying this sequence is to allow viewer to see
 what's going on with as little delay as possible).

Criterion: using a pair shutter goggles, we can see what each buffer
is displaying.  In case I, the scene is shown as expected.  But in
case II, some of the labels that are partly occluded by some other
invisible lables (looking through the goggles). 

We are thinking these possibilities:
	1. after swapbuffers(), the zbuffer forgets about previous contents
	2. two buffers share the same zbuffer
	3. there are some tricky in using zclear() (or czclear()) which
	   are unknown to us.

Thanks for any response or advice.

Greetings people!

I just received a quote for C++ 3.0 (SC4-C++-3.0) and Fortran 77 (SC4-FTN-3.5)
from an SG Express rep. Both products were listed in parentheses as being
"3.10 backend based", with a note from the sales rep that I needed to have an
R4000 based system to use them. Is this true? It sounds rather strange to me.

What is your interpretation of this:
(a) Only the R4000 systems have sufficiently updated software to support
	3.10 level compilers?

(b) Her statement was inaccurate, and she just means that these products now
	also provide explicit support for the R4000 systems?

(c) other?

Thanks in advance.

Yes, but that isn't really a problem, since it should never match

There is some tuning that can be done to help, but it is fundamentally
wrong to put thousands of files in one directory.

Consider it from the computer's point of view.  In such a bloated
directory, every time you tell the system to do anything with a file
name, the system must consider all of the other file names.  If you
create a new name, the system must check that the name is not the same
as any other name, and so must examine every one of the other names.
If you open an existing name, the system must search for that name, and
on average examine half of the other names.  When you use `ls`, it must
sort all of the names.

A particularly bad requirement is that the system must in principle
examine the disk for each and every name.  In a directory with a few
names, the system can buffer all of the necessary disk information in
main memory and avoid disk operations on second or subsequent
requests.  If you have an eggregiously large file directory, the
system's buffers will not be big enough.  The system will fill the
buffers from the disk with the first hundreds or thousands of names
(and inodes if you use `ls -F`) as it starts working on your request.
Then if necessary, it will read more information from the disk, into
those same buffers.  If you do a second operation, it will have to
re-read everything from the disk from the beginning.  On the other
hand, if your directory is small enough, it would all fit in the
buffers, and second commands would not pay the 1000X or 10000X time
penalty of having to read the disk.

The best solution is to use hierarchies.  Spread your files into
sub-directories.

I am trying to port an existing application to an SGI work station,
running IRIX 4.0.5.  The application uses nlist() to obtain kernel
addresses and reads kernel values via lseek() and read() calls on
a /dev/kmem descriptor.  It's an open-file lister, ala ofiles or
fstat, that I call lsof.

The nlist() works properly, but I have to strip the high order bit
(0x80000000) from the addresses it returns in order to avoid an EINVAL
from lseek().  If I do that, the values I get from read() seem correct.

I've even deduced (I think) how to read the user area structure from
some hints in <sys/proc.h> and <sys/immu.h>.  However, I can't find a
way to read the array of open file pointers, using the u_ofile pointer
in the user area.  If I strip its high order bit, I get an ENXIO error
from read().  The address appears to be in the kernel stack -- e.g.,
0xffffc808.

So, two questions for the gurus of this news group.

1. Is stripping the high order bit from kernel addresses the right way
   to use them via /dev/kmem?

2. How does one read from addresses of form 0xffffc808?

E-mail replies would be appreciated.

Thanks in advance.
