size discrepancy

-rw-r--r-- 1 jd jd 3616593920 Sep 29 21:56 Fedora-14-Beta-i386-DVD.iso
I burned Fedora-14-Beta-i386-DVD.iso to blank dvd.
One time I used wodim, and 2nd time I used growisofs.
After each burn, I would dd the dvd back in:
dd if=/dev/sr0 of=f14.iso bs=2k
In both cases the size of f14.iso was 10240 bytes larger than
Fedora-14-Beta-i386-DVD.iso.
So, naturally, I will not be able to get the same sha256 sum
as that of Fedora-14-Beta-i386-DVD.iso
So, how do I dd the dvd in and get the same size as original iso?
Perhaps growisofs and wodim are padding during burn.
If that is the case, how do I suppress it?

Seperate audio outputs for fedora- is this limited by my soundcard or the number of outputs on my motherboard?
by Samuel Kidman
Hello
Another audio question:
I want to be able to play one audio source through my headphones (say from
one application) and then play another audio source through my line out port
(from another application). Is this possible? I have an integrated
soundcard. The computer is a Hewlett-Packard DC7600. Just wondering if the
sound card on this computer is capable of piping two different audio sources
at the same time, and if so, how this can be accomplished using fedora and
alsa or pulseaudio. Maybe even Jack?

links, mc, lynx, etc. No console mouse support.
by Silent-Hunter
I cannot seem to get console mouse support working. GPM works for
copy/paste, but Lynx, Midnight Commander, and Links will not use the
mouse unless I run them as root or with sudo. Can anyone help me get
mouse access without having to be root?

Converting ext4 to xfs
by Suvayu Ali
Hi everyone,
I was wondering if there was any way I could convert an ext4 partition
into an xfs partition without copying around files onto a separate
partition and reformatting. The partition in question is my /home on a
volume group of its own.
I realised, lately I have been dealing with very large files quite
often. Ranging from few hundred megs to a gig or two. So I decided to
switch to xfs. Do you think its worth the effort?
Also since we are talking about my /home here, there will also be small
conf/settings files along with the large files. Do you think that would
be disadvantageous somehow? Would it make more sense to shrink my /home
and have a separate xfs partition in the created space for the large files?
Thanks for any thoughts on this.

LibreOffice Install Process.
by Michael D. Setzer II
I download and setup the 64 bit version of the Fedora 13 machine using the
following process.
Extract the gz file
cd en-US
cd RPMS
rpm -Uvh *.rpm
that went fine with no problems
cd desktop-integration
ran the redhat rpm
It gave conflicts with openoffice
remove openoffice
reran redhat rpm, and it worked in the installation,
but the links did not work. Turned out they were running
libreoffice instead of the libreoffice3 from the /usr/bin.
So, I just created a link using ln -s libreoffice3 libreoffice
Don't know if this is the exact process that was meant to be done, or if it is
the same with the 32 bit version?
Wondering if others have checked it out yet.

sound-level activated recording
by Samuel Kidman
Hello all
Does anyone know of a tool chain or a way of scripting this:
1. start recording from a line-in port as soon as the sound level goes above
a certain threshold
2.stop recording after it goes below the threshold for a certain amount of
time,
3. save the whole recording in some kind of PCM format with the file name
being the time and date the recording started.
One possible application could be security, but the application I'm going to
use it for is recording music.
Just looking for some resources or maybe one of you has done this before?
