For backup purposes you are completely right. In that case I prefer
products like FastBack which compress reasonably but are very fast
as well. For relatively small archives (the ones you usually download)
I think slower compression than PKZIP should be usefull as well (as
long as it delivers a better ratio of cource, like 5-15%). Decompression
should not be much slower I think.

Speed is certainly the main advantage of PKZIP. Nobody ever matched
them there.

Correct. I believe for most practical purposes ARJ is sufficient. But
I have to admit for large backups only the fastest is good enough.

One thing PKWARE is NOT fast at is fixing bugs and releasing new versions.
Could you be more specific on the information on the PKWARE BBS BTW?

When using maximal compression I collected the following results:

Result value is length of the complete archive. ZIP 1.9, PKZIP 1.93a, 
ARJ 2.30, SQZ 1.08.2.

File created with "echo hallo > hallo":
   SQZ    42
   ZIP    116
   PKZIP  116
   ARJ    110

File BCC.EXE included in Borland C++ 3.1:
   SQZ    281143
   ZIP    282304
   PKZIP  281620 
   ARJ    283934

This shows that indeed the meta information is smaller (looking at the
archive I think it has no central directory and has less meta info
per file). It also shows the compressor does a little bit better
than the rest (but with using much more time). It must have some
tricks not available in ZIP to achieve that.

>I guess it uses an algorithm very similar to Info-ZIP 1.9. 

I have experimented with my compression-killer-kit (TM) and it seems
very similar indeed. The dictionary parameters are almost equal
and it seems to use a comparable static huffman mechanism.

Agreed. The product has not much to differetiate it from the rest. Perhaps
it will be succsfull in Sweden (due to the native language support) but
it is not good enough to chalange ZIP and ARJ IMO.

I think I jumped the gun and misinterpretted your first posting.  I
thought you said that the algorithm had been published by the PATENT
HOLDER before they applied for the patent.  The law is that the *inventor*
can apply for a patent after the *inventor* has publically published
the algorithm/product --- they have up to a year to do so (this is not
true in most other countries).

So you can't just browse Scientific American for patentable
ideas unless you wrote the article.  You still have to prove "no prior
art" in a patent, meaning that if someone else published before you
did (or your patent application), then you have no grounds for a patent.

Back to the topic at hand:  I now assume that you meant that Ross Williams
published something before the *other people* applied for the patent.
Is that true?

It is available on garbo.uwasa.fi (just as about anything I believe :-)).

It is faster than ARJ 2.30 and tighter than PKZIP 1.93a.

  Are you sure? As long as you reveal prior art, I don't see a

System 7 runs as a process under A/UX.  If A/UX ran on top of the Mac OS,

Check your .profile or .login files.

If you are doing a 'tset' (for example) with either -m or -A, then it'll wait
for your input before continuing. Your <return> tells it to accept the
default...

You should be able to build 1.40 with cc with no trouble. I think
2.2.1 can be built with some user assistance. Make sure you use the
'-A 2' flag to cc (this increases its table sizes). Make a symbolic
link from gas (the GNU assembler) to 'as' in the build directory
(note: this means that you must build gas before building gcc). Tell
me where things fail if they do...

You could also just fetch the 2.2.1 binaries from wuarchive, unless
you need a tailored version of the compiler.

I don't think this is what was meant.  When you have this problem, just reboot
your mac.  When A/UX Startup launches, click on the cancel button and you will
end up in the startup shell.  At that point, you can do the command:

fsck /dev/dsk/c0d0s0 (or whatever scsi ID describes your root partition).

You might also want to add a line to the script like "trap 1 2 3 15" (I
think those are the important ones, might be good to check), to prevent
anyone with quick fingers from hitting CTRL-C and stopping the .profile
from executing.  Make the trap line the first line in the script.

First, the legal stuff. I following represents my opinion only and does not
reflect those of Apple Computer.

Okay, got that cleared up. I work at Apple as a contractor in the A/UX
test group. In my experience there, I would definately stay away from
drives by Micronet.  The reason:

1) I've had three fail on me in about a month and a half. These were brand
   new out of the box.
2) I know of at least two or three others that have also failed on coworkers.
3) They generate "Unit needs Attention" errors all the time. When running
   tests with A/UX, sometimes we're not sure if A/UX is broken, or if the
   Micronet is causing problems.
4) HD-SC setup fails to "see" them. Sure, they come pre-formatted for mac use,
   but that doesn't help when you are loading A/UX.

The micronet's have seagate mechanisms. I don't think it's seagate's fault,
but rather, the funny drivers/firmware that Micronet uses. Apple uses them
because they get them dirt cheap, but I would never buy one for myself.
