Ummm...different school of thought...write the code so the algorithm is
understandable *without* comments. Use identifiers & function names that
are concise, yet provide enough information to understand what is going
on. The purpose and function of the code should be immediately apparent
to another programmer. Comment only as much as necessary. Since it is
difficult to grasp what a hunk of code does if it is longer than 1 page,
try to keep functions short.
Compare coding to writing a report... use whitespace to set off
logically organized sections of code and use enough verbage to get your
point across, but not so much that it puts the reader to sleep...
Ideally, you sholdn't need *any* comments in the body of a
function/procedure. You give a 1 sentence prologue which contains a
description of the function (if you need more than one sentence, perhaps
your function is not cohesive enough and needs to be redesigned), a
description of the interface, and a definition of each of the
parameters. Do all of this *before* you write the code. Then write the
code as clearly as possible remembering that in *most* cases, coding
"tricks" are not necessary because the compilers can figure out its own
efficiency "tricks", but clear, understandable coding can save the next
programmer hundreds of hours and thousands of grey or yanked out
hair...;-)
*ALWAYS* code for the *other* programmer, because someday *you* may be
the *other* programmer...

How much memory is the machine.
Most modern distrubutions require >8Mb to install, even if they will run
with less.
I have a PS/1 happly running SuSE 5.3, but I have 32Mb.
30pin simms are pretty cheep these days. 16Mb will allow the install to
run and run X (if a little slowly). If you don't want to do this, install
the harddrive in another machine with more memory and do the install then
swap the drive back into the PS/1.

The problem with ISO9000 (and other quality assurance systems) is
that it assumes everybody's ability are equal and can work at 100%
efficiency all the time.
I think the main idea of ISO* is that they make people think that
you can simply replace a person because their work/methods are
documented enough to allow someone else to pick it up. In real
life that's not true.
Also, who decides the quality of the documents? Peers? I once
had to review a design document and after I read it, I just couldn't
believe it was written by a "professional".
Personally I believe programmers are artists, just like musicians.
Their creations reflect their mood and personality.

hi,
instead of updating your kernel modules, you should copy the new
compiled modules (i guess videodev, tuner, msp3400 and bttv) into
/lib/modules/KERNEL#/misc. to insert those modules into the kernel
at boot time i put lines like
insmod videodev
insmod tuner
insmod msp3400
insmod bttv
in my /sbin/init.d/boot.local file. you probably have to change and/or
add some parameters.
next you have to add the path containing your xawtv to your PATH. you
can
do that in your ~/.profile or ~/.bashrc (or whatever shell you use).
now you can open a terminal and just type xawtv and enjoy watching...
alternatively you can create a desktop icon to startup xawtv ...
good luck

Try changing the mode of the port.
Can you write directly to the device?
cat <file> > /dev/lp0 (or whatever lp yours is on)
As root. If so, might be a problem with lpd.
Otherwise I am tapped.

According to adaptec's web page (http://www.adaptec.com/) there is a
small difference between the 2940UW and the 2940UW Pro.
On the 2940UW, you can use put cables on any 2 of the 3 connectors:
68-pin external
68-pin internal
50-pin internal
On the 2940UW PRO, you can use all three simultaneously.

Hello.
We have Suse 6.1 with kernel 2.2.5 running. Now we want use our MO drive with
with 640MB medias. The kernel should support this but it doesn't work for us.
If we mount the device we got the error message that the device could not mount,
because of wrong superblock, to many mounts, etc.
After we create a new filesystem with mke2fs -b 2048 we could mount the media, but we
couldn't write on it because no space left on device.
The logfile shows us following:
...

Is there any patch for that problem? For kernel 2.0.36 the patches works but
