a subset of what Linux supports. Where is Linux behind Be?

Bill,
on the apmd home page there is a reference to a patch for the 2.2.x
kernels:

Note this stuff is marked ALPHA (pre-beta), and that you're using it at

No I'm not dumping Linux, thought this would get people's attention.
I am presently running NT as my desktop with an X server for my
various headless Linux/Unix machines in my basement. Works reasonably well,
but I would like to dump NT completely (minor instability, lack of
APM, it's tieing up a PPro for mostly being an Xterminal, not to
mention the inability to do sound thru X). One application I have to
have that does not seem to exist for Linux is the ability to use a
serial scanner. Presently all my paperwork passes thru a visioneer
paperport. I would consider buying a new scanner if I can get the
equivalent functionality (clickless/automatic scanning and very
compact scanner). I checked the SANE pages, but there does not appear
to be anything for Visioneer or the HP serial scanners of equal
capability. I do not need the paperport _software_, since I figure I
can whip up whatever I need myself. But I would like to not deal with
device drivers. Anyhing?
thanks,
BM

Subject: What's the best way to do process communication ?
From: Markus Kohler <[EMAIL PROTECTED]>
Date: 02 Feb 1999 16:46:07 +0100
Hi,
I need a way to communicate between two or more processes on the
same machine and exchange data as fast as possible.
The data are arrays of double's with a size
from 10^3 elements to 10^6 elements.
Performance is VERY critical.
What should I use, shared memory, FIFO's, message queues or somthing else ?
I know that shared memory is usually the fastest but since it cannot grow
dynamically it seems to me that it is not really an option.
(Please cc: [EMAIL PROTECTED] since Im not regulary reading this newsgroup)
Thanks in advance,
Markus

Subject: Linux apps in win2000 port news!
Date: 2 Feb 1999 15:58:39 GMT
Reply-To: [EMAIL PROTECTED]
Hi all,
Just saw on the biz wire that a company http://www.interix.com has
developed a 64 bit application that runs a a unix/linux emulator within
the MSoft Win2000 (NT5.0) platform environment. They want alot of
Linux apps ported to their API interface so that Unix runs within Windows.
Seems kind of ironic since Linux is trying to run Windows apps in Unix;
but we don't have the source code to their stuff, but they have ours.
Hmmm! seems like there isn't any competition again. Msoft is supporting them
though.
They have a limited list of things they want ported such as gcc (all compilers and
assemblers) and emacs and Tex to name a few. You have 2.5 months to do it
by -- they end of January 1999. Anything else is nice but they won't pay for.
Those they'd like you to port will only pay a maximum of $1000 to a cheap
payment of $500. They didn't mention [conveniently] that they would like the
linux kernel or Sunos x86 kernel etc to run within the interix Win2000.
The reason it was supposed to be done by the end of January 1999 (now past)
is due to todays press release about this product.
Hmmm! if you can't get the Unix software vendors to port their stuf from Unix
to Window Nt, then make the Unix apps run within NT! In this way you can
say that your OS is a engineering workstation.

Look at XEmacs for a sample implementation of multiple DND protocols.
Between CDE, KDE, GNOME, OffiX and probably others, there are quite a
few to choose from. I think KDE and GNOME might be using the same
protocol but I don't know for sure.

I am interested in where you found all the information about X windows

haven't found much good information on programming custom GUI toolkits.

Were you joking with this question or is it really an easy kernel

I have to set it to 75 Hz and 1024 x 768 in order to view anything, I

Let's see, use of nice is tuning the system, but allowing interrupts
during transfers isn't? Not having DMA and compensating is "broken" but
not having more or faster CPUs is broken, you just have to use nice?
It sounds as if you have defined broken to mean "having resource
limitations diferent than my system." If you have enough CPUs you don't
need to be nice ;-) The beauty of Linux is that it will run on limited
hardware.
And I would be *very* careful about -u, on some chipsets it can corrupt
the disk. Always have a backup before doing things like this!

Don't know about that, but I do know that for me I can hear the
