What sort of comparison? Speed? Memory
usage? Usability? Since all three
toolkits work with three different
languages (Java, C++ and `mainly C but
often Scheme' respectively) you should
pick the right toolkit based on language,
availability and licensing. There's not
really a way to compare the toolkits side
by side on the same application.

What processor are you using? There's no
real problem with Java + TYA + Swing
on a Pentium II, but it can be a bit
painful on earlier models.

I'm in debian, and I would also have to comment a line in /etc/isapnp.conf
to do that.

Date: Mon, 25 Jan 1999 09:59:28 +0100
Hello,
did anybody get the Soundcard "miro PCM12 Rev. E"
working ? The soundcard contains the opti-chip 82C924.
The loading of the modules
insmod soundcore
insmod soundlow
insmod sound
insmod ad1848
insmod uart401
insmod sb mad16=1
works fine. Only the last module
insmod mad16 io=0x530 irq=9 dma=1 dma16=0 mpu_irq=10 mpu_io=0x330
does NOT work with the stupid error-message:
/lib/modules/2.2.0-final/misc/mad16.o: module_init: Device or
resource busy.
The kernel (/var/log/messages) gives no error-messages. There
is also no irq/dma-problem, because I checked the /proc/dma
and /proc/interrupts. Also (in the meantime), I tried all irq's
and dma's.
I'm afraid that the reason for the problem is, that the
opti 82C924 is a pnp-chip. (Opti sayes this.) But the soundcard
miro PCM12 Rev.E is NOT pnp. Also pnpdump gives nothing.
Perhaps the miro must be initialized which is not possible
under linux. (I have NO windows to check this.)
Thanks for all hints.
Karsten.
The mad16-module can also not be loaded with kernel 2.0.36.

Before everyone goes down the performance path, it seems like I need to
make clear that I'm not interested in that aspect right now. I'm looking
for a comparison on the programming level: APIs, ease of development,
general approach to GUI creation.
Thanks,
Michael

As I said, maybe they've improved it somewhat. If I recall correctly, the
machine in question was running version 3.51, maybe version 4 has fixed it. I
can't recall the hardware, think it was have been a dual pentium pro 200 with
plenty of ram. I can remember that if it took 5 minutes to log a directory in
file manager, you were happy. And you had to leave the screensaver off, if
you turned it on, due to win NT brain damage, it seemed to get priority
over whatever other tasks the machine might be performing. And it wasn't like
the thing was being overloaded, it was only functioning as a relatively low
bandwidth web/ftp server.
It's not like I still have access to the machine to test it under NT4, so I
couldn't tell you whether or not this is still the case.

There is a 2500 year scholarly tradition of interpreting those words.
If you haven't heard of it, that shows in what dire straits humanistic
education has fallen in China in this century.

I think those verses do help people to liberate their thinking from the trap
posed by words. Look at all those Chinese (and other) computer hackers who
mix English into their native speech. Much of that is due to the inability
to think in "eternal" notions and find appropriate approximations in the
cultural context that they speak in. These people no longer have any proper
thinking, they ownly echo words like parrots.
Although, I think there is even some wisdom in the sentence
"The Tao that can be implemented is not the eternal TAO".
There is a thought basis to operating systems that can't be grasped
and represented in one system. Everything that has been consolidated
into a real system is necessarily inflexible and no longer state of
the art.

Yes, until now Linux doesn't seem to provide a way of reserving resources
to the most important processes even under adverse circumstances.

The "Classic of the Way and Virtue" (which starts with "The Tao that can be
implemented is not the real Tao") is from about 600 B.C. Still, I think one
can reserve almost anything as a trademark for a limited area of
application, such as computer O.S.es.
I found the TAO OS article very tedious to wade through and gave up after a
few paragraphs. Usually I suspect that when an author fails to put the
important points in front, the rest won't be rewarding. Maybe the author
can give it another try. I would be interested in good new OS concepts.

Well, the mouse cursor being responsive over an application doesn't mean the
application will be responsive. When the system is bogged down, everything
is bogged down. A responsive mouse cursor just gives you the illusion of a
low load.

I don't see the point. You would have to keep the handling of the mouse
cursor in separate job, run it as a real-time process (using an appropriate
real-time kernel) and provide for IPC across rings beween the mouse handler
and the rest of the OS.
All that just to maintain an illusion? I'd take a jumpy mouse cursor over
that any day. And don't forget handling anything in real-time (i.e.
preempting the scheduler for it) is always a risk. If for some reason the
mouse handler goes crazy, it will grab all the cycles and lock your system
inside the real-time ring.

Hold a mouse button down and see how Windows goes into a frenzy while you
