I think the biggest question is, *WHICH* version of WDM
are you going to emulate?
Despite promises many years ago by mickeysoft that the WDM
I/F would be the end-all for device driver writing, it has
continued to migrate in such a way that a driver written for later
OS's will not even be loaded under their original release of WDM.
Given their current rate of change, I personally doubt that a final NT5
driver will load under Win98 (whenever NT5 / Windows 200x is released).
Maybe you could do the thing that they can't seem to do -- make everything
work?

I would either go for it and take the (guess: tiny) risk. You still can

that many descriptors with the same interface. I doubt though you'll ever

Subject: kernel 2.2.0-pre[1-6] and ISDN driver
Date: Sat, 09 Jan 1999 18:20:01 +0000
hi all,
i found a problem in the usage of the kernel driver. this problem exists
in pre1-pre6. the kernel crashes directly after boot (without any dumps)
if the isdn/hisax driver is compiled statically. if built-in as a
module, the isdn driver works fine.
is it a bug or a feature ? (i'm using the teles 16.3(non-pnp) card).
bye,
Chris.

Irrelevent to my point. If you support Qt/KDE, you are enhancing the value
of Qt, a commercial product. You are not an *equal* party in the software
license contract. If you support Gtk/Gnome, you are supporting the Gnu
Project, a non-profit organization who's goal is to develop a free OS,
libraries, applications, etc. It just so happens Redhat is supporting the
Gnu project. You not an *equal* party in the software license contract.
Redhat has put out more lines of code under GPL/LGPL than Troll Tech has
put out total. AFIAC, Troll Tech is cheesey.

I said Gtk/Gnome apps. Many apps are listed as Gtk only because:
1) Gnome is not finished yet, and many systems do not yet have it
installed. Nearly all Linux dists have Gtk installed by default.
2) The Gtk language extensions have not yet incorporated the Gnome
widgets.
3) Several are both Gtk-only and Gnome apps. They have Gnu autoconf setup
to use Gnome support only if ./configue can find the Gnome libs. So they
list it as a Gtk app.

See above,
Here's is what I find querying the Freshmeat search engine:
Qt - 32 Entries
KDE - 67 Entries
Gtk - 160 Entries
Gnome - 48 Entries.
That's 208 vs. 99.
Looking at the kde.org app list there's about 280 apps. Looking at the
gnome.org list there's about 148 apps. But looking at the sunsite gtk list
there's another 148 apps, of which 20 are also Gnome apps (see 3 above).
So that's 276 deducting for the 20 duplicates. Pretty much even. But
Gnome is about 1 year behind KDE. Wait until the language extensions
incorproate the Gnome widgets.......

Yes. Of course, they will have to exclude any code that they borrowed from
other GPL programs.

They haven't. What they have (reportedly) done is arrange for their code
to be released under the GPL should certain conditions (such as bankruptcy
of Troll Tech) obtain. However, someone will still own the code and that
someone could still release it under an additional license.

Qt is presently under an odd sort of non-free license. It looks like Qt
2.0 will be under a free license.

Yes. It is true. I tried (in vain, of course) to find an astrology program
written for Linux. No dice. There are dozens of serious ones for both DOS and
Windows (and hundreds of trivial ones, too!) And skip the anti-astrology
flames, pls. And where are the PC Hot Rod dynamometers, simulators, databases,
and calculation tools for serious racers etc., that abound in the DOS/Windows
world? Linux may be the next wave, but it has yet to understand the common man
or the common user, with the accent on common. Or a good graphical math
program; windoze has three or four that display 2- and 3-axis and 4-dimension
math functions. (I have not been able to get GNUplot to run....)

Windows with native DOS and legacy-16-bit support is going away. I am moving
to Linux as I will not go to Bill Gates' renamed-NT-land. Linux has a good dos
emulator (my main application is still WordPerfect 5.1 -- even after nine
years and three Windoze versions of WP.) This seems to me a good time to
migrate to a mature and stable 32-bit system that WordPerfect files are
currently useful on -- Linux.
I think you may be missing the Linux balloon ascending, but your kite is tied
to another OS -- Solaris. I'll bet both of us will run multiple OSes for a
long time to come.

All right. But KDE, while very good IMHO, is too Windoze-like. I don't like to
be reminded of the dreaded bloo screen of death. And it sucks up memory
bigtime if you surf the web with its browser or with Netscape. But you guys'll
get it right. And I'll have been here early enough to watch it happen. And
maybe even learn to help.

hi,
I am still having trouble with linux.2.0.34. The libraris
are all linked and the names are resolved. New applications
all complain that they cannot find libc.so.5. It exists,
and it is a function of the linker. It makes recompilation
problomatic... Nothing works if recompiled. Big, little,
nothing. The system seems to run just fine. sigh.
I back ported 2.7.2.3 and it does the same thing.
Any help?

Andrew, or the AUIS (Andrew User Interface System) is really an Office

Emacs does under X - yea, it has a GUI, but it is way easier to use the

This is because a bug in klogd 1.3, it check the map file's version by an
symbol in it, but if the release
that uname return contain any "pre" it will fail to match the version.
In final version, it'll be OK.

You must be using an old klogd (etc from Redhat) it it cannot load module
table correctly because of the kernel's change since 2.1.12
You can download the source from Debian and it has fixed this problem.

The size of a fd_set is FD_SETSIZE which defines the maximum number of
fd's that can fit in the type fd_set.
max_open_fd = sysconf( _SC_OPEN_MAX );
Returns the configured upper bound which may be less.
The maximum number of fd's varies and is typicaly one of
256. 1024, 4096
There are some systems that go larger than that, but not too
many. A lot of code is dependent on the "small contigous array"
approach. It's a reasonable way to do it. If you want to be
truly abstract, use a hash table.
