Good, know if we can convince apple to port it to a public domain

So, if I understand well, these users you are talking about are
free to post to col.help, but they are forbidden to receive email !?!?!
So, pray tell, what happens to the answers that are sent to them ?
A standard netnews rule of thumb is that if a thread becomes too 
specific, or obnoxious, it is taken to private email. That's precisely
why the current project is going to use email to attract posters'
attention to "good housekeeping" hints. After all, the monitoring
program could POST automated replies to the newsgroup, and THEN the
complaints about waste of bandwidth would be valid.

BTW, these sites have not yet noticed, that posting to ANY newsgroup
causes you to receive email  (including now commercial junk mail) ?

I'm sure you are doing what you can in an imperfect world dominated by
moronic monopolies and governments, but posting to netnews with no email
feed clearly doesn't follow netnews customs, and promotes noise in the
newsgroups (a capital offense IMHO).

And finally, a HELPFUL SUGGESTION: Why don't you suggest (and implement
on your site) that sites that forbid their users from receiving
email mess up the From: field (for example to only a name, with no
email address) of their local posts. Some other fields may have to be
tampered with, but the monitoring program clearly won't try to email
when it can't get a decent address to email to. As you forbid these
people from receiving email anyway, that would also avoid sending
answers into a black hole.

Sorry guys, switching to French here, by sympathy for Rene:

Subject: Kernel compile dying w/SIGSEGV
Date: 28 Mar 1994 15:54:09 -0500


Greetings,

Over the course of the weekend, I attempted to recompile the kernel. The first
attempt was sucessful. However, subsequent attempts  failed with what would
appear to have been segmentation violations. A representative error message 
follows. The strange part of it though, is that the compile failed at a very
early point in the remake on one attempt, but breazed right through the same
point in the compile on a subsequent attempt. It's obvious to me that there
are not any errors in the source that are generating such problems. e.g.
dividing by zero. Has anyone else had such experiences? How about one of the
compiler and/or kernel experts speaking up? What would cause the compiler to
fail with a segmentation violation when one doesn't actually exist? What 
would cause the kernel to generate such a signal and kill the compiler?

A representative failure message:
. 
. 
gcc -D__KERNEL__ -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -pipe \
     -m386 -c -o init/main.o init/main.c
gcc: Internal compiler error: program cc1 got fatal signal 11
make: ***[init/main.o] Error 1
cpp: output pipe has been closed

Oh yea, 'signal 11' is defined in /usr/src/linux/signal.h as 'SIGSEGV'.

Cheers,

Doug Donahue

[etc]

I used to get this all the time. Then I changed the timing on my motherboard,
and it went away completely--I haven't had a problem since, and I've rebuilt
the kernel many times.

This has been discussed before, and the culprits blamed were ISA<->memory
transfers, motherboard memory itself, and the phases of the moon. It
would appear that simple tests, especially DOS- or Windows-based tests,
don't pound the machine hard enough, so rebuilding the Linux kernel is a
pretty good test. In any case, you can imagine that if gcc started paging,
and one of the paging transfers had an error in it, thus changing the
code, you could get a seg. violation. One problem with the kernel, at
least the last time I looked, is that a lot of the hardware traps
are mapped to one signal, segmentation violation. I'm not sure if that's
a POSIX thing or what, but it does make figuring out what's going on 
a bit of a hassle.

Anyway, if your motherboard has lots of settings like mine does, start
changing things like ISA bus speed, DRAM wait states, ISA bus wait states,
etc. If it doesn't, you might be SOL. I think the thing I did that made
the most dramatic difference was slowing the ISA bus down to 8 Mhz.
A lot of motherboards have a 12Mhz setting, and many ISA bus cards
are unreliable at 12Mhz. Others have found that replacing SIMMs cured their
problems. 

Also, if you have a 50Mhz DX motherboard, like I do, you might just want to
replace it with a 66Mhz DX2...Oh, another thing I've remembered--when I
first got my motherboard, it crashed a lot, and the problem turned out to be
that I had a 50Mhz motherboard with cache RAM for a 33Mhz motherboard, so
make sure that your cache SRAMs are fast enough.

I have to disagree with this.  I have an old 8088 sitting around the
house (acting as a dumb terminal) that I was thinking of upgrading
to run Linux.  I finally decided it was cheaper to get another system.

[I added $175 to cover a 170mb IDE drive, $45 to cover 1.44mb

: IBM486SLC2/66 - $300
  170mb IDE HD  - $175
  1.44mb Floppy - $ 45

: Mono VGA      - $115
: VGA card      - $ 45
: ---------------------
  Total          $1000

Looking at the prices for re-manufactured Gateway 2000 boxes 
(current prices can be gotten @ 800-846-2410), I can get a 
486SX-33 (4mb ram (64k cache), 1.44 drive, WD VGA w/1MB on MB, 2S/1P,
and a keyboard for $399.  To bring it up to (and past) your config
with 4 more megs of RAM (total 8 megs -- not purchased from GW2k), 
a 14" color monitor, and a 170mb HD would cost:

  RSX-33        - $399
  170mb HD      - $175
  +4 MB RAM     - $150
  SVGA 14"      - $199
  --------------------
  Total           $923

All of the GW2k prices are for re-manufactured parts, so they
aren't brand new, but have been tested and carry a 1 year 
warranty and lifetime tech support (for original purchaser).

This is the route I went.  I could find "Joe's Garage" PC's
in the LA area for the same or slightly lower prices, but
I felt a little more secure, that GW2k might be around in a
year if I had problems.

And this way I can still use the XT as a dumb terminal :->

  Thanks for all the info that people have sent my way.  The posts got a little 
confusing there for a while(kind of my fault) because I had originaly 
cross-posted to many different operating system groups.

  I think I'm going with a Zeos system.  It's not my first choice, but it has 
about what I want(I think) and I have to buy everything from one company(plus 
it doesn't hurt that the guy signing the money order seems to like them).

here's the specs:
    Pantera 60 or 66 Pentium system

    Diamond stealth pro PCI 2mb vram(maybe 1mb) S3928
   
    on board fast scsi2 controller (adaptic 6360 chip set?)

    Nec 17" monitor (don't know which one yet, fg, fge, or fgp)



  I think the Diamond should be pretty well supported(even some Xfree users use 
it :) it got the highest score on the lastest  Graphics card benchmarks 
survey(21 Mar 94)).  I think it should be pretty compatible on the basis that it
uses the S3928 chipset.  Anyone find different.

  The only scary part is the scsi2 controller.  All the info I have is that it
is an adaptec 6360 controller chip.  Anyone using this?  Scsi is very important
as many of the items here are unix/scsi already.  Obviously they must have 
dos/windows support, but does any one know of other operating systems(OS/2, 
Linux(Xfree86), NeXtStep, NetBSD(Xfree86)...)?  Should I just go with an IDE 
drive and get the $49 chip for scsi support also?

  Any comments from all you OS/2, Linux(Xfree86), NeXtStep, NetBSD(Xfree86) users
are always welcome.


thanks again,
  Jeff

P.S. I do know that diamond is being anal about some sort of code release policy
so XFree86 won't support it, but people seem to be using the VLbus version fine
with the XF86_S3 server(version 2.0).
