Windows should never see real Linux partitions.
Sounds like you may have created your Linux partitions with something that
thinks they are FAT partitions (you didn't use DOS/Win FDISK to do that
did you?). From Linux fdisk see if the Linux partition types are Linux or
Linux swap and if not, make them so (t fdisk command). If they are
already Linux partitions, try toggling the dos compatibility flag on your
Linux partitions. Then if they still show up in Windows try removing any
disk devices from Window's device list and reboot.

"Experiment"? It sounds like you already know what you need to do:
cd /usr/src/linux
make menuconfig
(change all the *s in the Sound part to Ms)
make dep bzImage modules modules_install
etc, etc.
then run lilo and reboot.
You shouldn't even have to do anything manually to get sound back after
you suspend. Check the man page for apmd, paying close attention to the
-r option. I have a small script hooked in to apmd -r that unloads and
immediately reloads the sound module, which prevents suspend from messing
up my sound.

Date: 26 May 2000 13:35:31 GMT
Reply-To: [EMAIL PROTECTED]
Does anyone know if the kernel that comes with Mandrake 7.0 is patched to
be able to play DVD? It comes with a program called 'nist' that is
supposed to be able to play DVD, but nist appeared to be still under
development at that time and docs are minimal.
I tried to follow a more recent DVD-Playing-HOWTO (May 2000) using the
LiViD utilities, and 'ac3dec' compiles, but 'oms' does not, due to
undefined variables and other problems. Since 'oms' appears to be what
hooks these to the kernel, I think the Mandrake 2.2.14 kernel might not be
patched or at least not recent enough.
Is there a kernel with DVD support that would plug into Mandrake 7.0
easily or do I need to get a generic kernel? I did link /dev/dvd to
/dev/hdc (my cdrom). I am not using the built-in sound modules anyway
because my Sony F450 needs the commercial opensound.com drivers. But I do
need pcmcia support for my nic (which works currently).

Does the BIOS see the hard disk? If so, does it have it correctly
identified (cyl/heads/sectors)? If the BIOS cannot see the hard disk
properly, then it will not be able to connect any operating system to it
appropriately.
If the BIOS does not see the hard disk, then you need to work on it
from that point of view. You can probably find some AMI reference on
the net if you do not have documentation from the computer. Sometimes,
you can tell a BIOS your disk is a dumb type (like type 1), and then
have the BIOS see enough of the disk to run its own update program to
correctly characterize it.
If the BIOS does see the hard disk, then try loading up on OS you
can completely run from a floppy or RAM (rescue disk distributions of
linux are available on the net, as is DRDOS, or you may have an image on
your RH cdrom that you can rawrite/dd from another machine). Then try
to access the hard drive from the rescue OS. You may be able to
fdisk/format/set-up-file-system then.
If you still have problems, post more info.

I don't know of any links to the info you want and I'm not an authority
on neither PHP nor Java but I do know that PHP is executed by the server
and that Java programs are executed by the client. So if you expect to
have a lot of clients connecting to your server you have to remember
that large PHP codes might slow things down for you (this might not be a
big issue).
And as usual, the choice of programming language depends on what you
want to do. Are you looking at PHP and Java for doing queries to
databases or for doing GUI stuff or something completely different?
Which language have the best API for the tasks that you want to perform?

Is it a hot ethernet connection? I find that when I don't have my system jacked

Mine varied wildly, got 20k connections to almost 50k. Mail was

I guess the thing is "what do you expect for nothin'?". I broke down

Date: 26 May 2000 14:32:32 GMT
Hi,
Like a few other people out there it seems I'm being plagued by Netscape
and its horriblness.
The version that comes with SuSE 6.4, 4.72, consistently exits whenever
trying to run anything via a plugin (and most other things too), and my
friend now has had it do the same when trying to enter a password for a
site.
The error it always gives is "Bus Error". This friend is now returning to
windows purely because of this, he needs to access a web site and he can't
do it on Linux. Period.
*Is* there any definitive answer to this continual Bus error problem, other
than downgrading to 4.71 (and on my SuSE install, at least, it won't even
work anymore). 4.73 seems to have exactly the same problems.
Strole on Konquorer, I'm utterly fed up Netscape's shitness. It's holding
back people here from going fully Linux as we *still* don't have a competent
web browser.

Actually, Java applets are executed by the client. Java applications
(including JSP pages) are executed by the server, and deliver results as
HTML pages to the client.

Subject: Re: PHP vs Java

I have done a little bit of both. There is a fundamental difference between
the two which IMHO makes JSP a little sloppy for a large volume production
site. It has to do with the fact that the JVM has no notion of class garbage
collection. Once a class is compiled and loaded, it will remain in memory
for the lifetime of the VM (even if no instances exist).This means that you
have to shut down and restart the JSP engine for it to load the new versions
of your beans whenever you need to modify them. That's not the case with PHP
because server side scripts are interpreted every time they execute.
JSP's advantage may be speed (JIT compilers like IBM's JRE have been getting
really good) but the new Zend engine in PHP4 may make that a non-issue. Has
anyone done a benchmark?
Another thing I dislike about JSP is that the mapping of CGI parameters to
bean properties only works with Strings and nothing else. So you have to
deal with type conversions and validation in your Java code. Also, JSP uses
cookies for session management and I think it's the only way they have
implemented that. With PHP4 you have the option of using URL parameters (I
believe the links can be automatically modified to contain a session
argument).
Just a few quick thoughts

Changes to a basically working system almost always introduce new
bugs and problems, but you can't make improvements without some
change. Without some kind of unit testing as soon as the code
becomes complicated enough that you can't trace it in your head
you have no way of knowing if a change is an improvement or
not, or how likely it is that you just broke a lot of other things.
If you are trying to fix an existing bug you might take the
approach that things can't get any worse and plunge ahead anyway
and if you are doing something entirely new you don't have to
worry about existing code depending on current behavior but
that phase is mostly over in Linux development.

Try putting a '&' after the command. The following line executes the
script 'child.sh' and saves its PID in the variable 'CHILDPID':
child.sh & CHILDPID=$!
This might or might not be what you wanted.

Thanks for pointing out this problem. I have to teach Linux and bash to
people with Korn shell experience, and like to be able to mention differences.
Since bash and ksh claim "POSIX" compliance (at least, to some greater extent),
they should work alike.
It's hard for me to understand why bash would spawn child-processes to
implement the pipe, but that seems to be the "excuse" that the FAQ uses.
It would seem that, if Korn shell can "make the connection" without a
subprocess, bash could also.
