Acorn is an UK company that make computers running their OS, RISC OS.
They're mainly popular with schools. The Acorn Archimedes 4000, which I
used, had RISC OS 3 - it was embedded in a ROM chip, which was secure
but not very upgradeable. It had a simple desktop interface - quite
similar to Windows, come to think of it, except it was a few years
before that. It was extremely stable and easy to use though - I can't
remember a single instance when it crashed. I believe it's still going -
I heard something about a RISC PC and I think they're on something like
A8000 or A9000 now. Very underrated - the one I used was very good for
its time, though I don't know what they're like these days.
Acorn were responsible for the BBC Basic computers - ancient, chunky
text based computers which I have used once or twice.
A quick search, however, has turned up http://www.acorn.co.uk/acorn,
which shows they're still going strong. Take a look at
http://www.acorn.co.uk/acorn/products/ for their latest offerings. I see
they still only require 8Mb RAM :-)

it seems under IRIX, the limit is the system's stacksize, which you
can only change to the corresponding physical RAM and not beyond.
the stacksize on my Linux box is 'unlimited'...perhaps the limitation
is not in the system, but the compiler????
I've tried with an array that exceeds the physical 512MB of memory on
the Linux box. The compiler does not seem to complain untill
beyond 1GB, but well before 2GB. It's pretty hard to tell, I guess
without a machine with 2GB of physical RAM on it, but I am trying
to decide whether to buy one or not, so...

Professors, like most groups of human beings, vary a lot in how well they
take criticism. The better ones often encourage debate and don't mind
being shown to be wrong about something. They may even reward students
who can do this by offering them research opportunities, one-on-one
instruction, etc. Of course, that doesn't do you a whole lot of good if
the professor you're showing up is one of the BAD ones, but I'd hate to
see students as a whole stop thinking critically and raising those points
in class. That'd be the death of higher learning, IMHO.
(BTW, I'm speaking not just as a former student but as a former
professor, though not in the computer field and only for a brief period.)

Subject: substituting ppp0 for eth0 for vmware virtual NT machine
Date: Fri, 20 Aug 1999 18:42:12 GMT
I have a working install of NT4 under vmware on my Redhat Linux 6.0
notebook. I set up bridged networking and the virtual NT machine does a
great job of seeing the network via the eth0 connection that Linux has.
However, when I take the notebook on the road and use PPP, I do not boot
up with an eth0 connection. VMWare comes up saying it can't find eth0
(no surprise) and therefore the virtual LAN card doesn't come up. So the
virtual NT machine has no way to speak to the outside world (including
the Linux box it's running on.)
This is a problem since I now have no way to share the virtual file
system. I can't use the vmware-mount.pl since it doesn't support ntfs.
It didn't work for me to install to a rawdisk partition, so I can't just
mount straight up. I was using samba to talk back and forth happily,
but without networking in place, that's a bust.
I am curious if anyone has a way to fake out vmware so that if I have a
ppp0 connection, it sees it as an eth0 connection and comes up happy.
Thanks in advance,
--Tim

Trying to manage some strange parallel port device, aren't you?
Really there are two ways to go:
1. The right way
convert your program to kernel driver, which provides some special
file in /dev, which can be accessed by read/write and suitable ioctl
operations.
Linux kernel now have special provisions for multiple devices on
parallel port, so read parport docs in kernel.
Then write a program which provides interface with your device file
for users and control user access by permissions on your special file
in /dev.
If your device is widespread enough - say, parallel scanner and you
open your driver code, many people would be grateful to you
2. The quick and dirty way
Read a section about "Changing process persona" in info libc
Make your program setuid root and make call to seteuid(getuid())
just after calling ioperm.
Than make your program owned by root and chmod u+s it.
Now your program would start with effective uid root, and thus be
allowed to do permio. After it take permissions to read/write ports,
it would give up root privileges and continue to work as invoking
user, retaining rights to use ports.
Of course, having yet another suid-root prog is not good, but
it would do the job.

I have never had Solaris give me any problems, but then I
have used Linux way more than Solaris. I also don't have
Solaris configured for the Internet, as I don't know how? If I
could find out about a 'hosts' file or something similar, then I
could connect, as I need a router configured, and the default
Solaris install, does not seem to allow that. That's one thing
about Solaris, it has a another learning curve, and the
administration tools are not apparent.
Besides being stable, Solaris has a total 'out of the box'
experience, and the CDE includes almost everything you would
want and need to do as a user. I believe that the KDE is
modelled after the CDE. The CDE is slick, functional, and
stable, has much more polish than the KDE, and everything works.
The installation was easy, and recognised all my hardware
without any problem. One neat thing about Solaris, is that it
can be configured and the x-sever selected to run any language
support you wish, so the whole desktop and applications change
language.

Plenty of possible reasons:
- Quality of the DACs - how accurately do the digital sample levels
correspond to their intended analog voltage levels? Are they deep
enough to handle the bit-depth you're feeding them or are they taking
shortcuts?
- Quality of the timing chips - when you request 44.1kHz, what are you
actually getting?
- Quality of the pre-amplifiers - how much crosstalk is there between
the channels? How much noise is introduced?
- Quality of the analog effects - when you adjust the treble, bass, gain
and other controls, how much adjustment can you make? How much
distortion is introduced by the adjustments?
There are other distinguishing features that come into play if you're
not just feeding a PCM audio stream as well:
- Variety of analog effects - stereo wide, "spatializer", compression,
reverb, and other features may be present on some cards.
- Quality of the FM synthesis components, and quality of the ROM
programs used to generate FM synthesis sounds from note-events (like
from MIDI)
- Quality of the audio-in digitizers - what bit depth and sample rate is
supported? How good is the stereo separation? How much noise is
introduced?

Date: Fri, 20 Aug 1999 19:31:06 GMT
I was wondering if there was any problems with Joliet CDs and the
2.2.xx kernel(I've noticed with 2.2.7-11). I burn CD's under windows with
DirectCD (on a external 2x HP 7200+ on the printerport, not that it
matters, they are horid devices anyway), and when I get them back home and
mount them under linux, the file sizes are totally wrong. Like, I've seen
200 meg files under windows become 10 megs in linux, 40 meg files becoming
3 megs, it's madness. So I have to mount them under windows and copy the
files to the linux box via samba, and reburn the CDs under linux to get the
sizes correct. Has anyone heard of this? I've scoured the web looking for
answers and have had no luck, and no one in my IRC channel (*Shameless
Plug*) has heard of this before. I'd love any advice anyone can give me.
Many thanx in advance.

2.3.13 is a development kernel and will have lots of bugs.
report the details to the kernel dev team, and it might help
