Got a bit of a question/issue that I'm trying to resolve. I'm asking this of
a few groups so bear with me.
I'm considering a situation where I have multiple processes running, and
each process is going to access a number of files in a dir. Each process
accesses a unique group of files, and then writes the group of files to
another dir. I can easily handle this by using a form of locking, where I
have the processes lock/read a file and only access the group of files in
the dir based on the open/free status of the lockfile.
However, the issue with the approach is that it's somewhat synchronous. I'm
looking for something that might be more asynchronous/parallel, in that I'd
like to have multiple processes each access a unique group of files from the
given dir as fast as possible.
So.. Any thoughts/pointers/comments would be greatly appreciated. Any
pointers to academic research, etc.. would be useful.
I've got an F10 install running well, and I'd like to move the system to
a flash disk. This flash will become the boot device for a small system
I'm building. Can I just use "cp" and end up with a workable system? I
know that I need to do a grub install. Anything else?
I'd appreciate any clues about what I need to tweak on the resulting
flash to get it booting/running.

My server has 5 SATA drives. I have two pairs of Intel stripped raid
(FakeRaid). These are drive C: containing XP Pro and D: containing
Vista 64. I decided to try out Fedora 10 and added a 5th standalone
drive since I knew that Fedora has problems with FakeRaid.
During the installation I added an upgrade from Hans de Goete that
allowed FC10 to see the raid volumes and I was able to successfully
install FC10 on the 5th drive. I've tried this with both the 64 and 32
versions. The install completes successfully and I can use the rescue
disk to mount the installation to check it out. So far so good.
My problem is that I can't find a way to boot FC10. I'm using a Vista
boot menu now for XP and Vista and wanted to add an FC10 option. I've
tried using EasyBCD but can't get it to work. I don't want to mess up
the XP or Vista installs as I need those for my business. However, I
would really like to see if I can migrate some of those applications
over to FC10.
Is there an easy way to boot FC10 without messing around with the
I have upgraded to kde 4.2, and two things catch me right away.
1. Switching the kde thing back to menu, I see kontrol listed, but its
apparently a dead menu entry, not even a busy pointer when I click on it.
2. Under F8, my logitech keyboards media keys for mute and volume control Just
Worked(TM) without me doing anything. I think this may be related to audio in
general cuz none of the system sounds are working although I can listen to
news video and such. The root of this may go all the way back to the fact
that the system finds 3 audio outputs, and seems to want to default to the
intel HDA built into my HD2400 Pro video card, and which is not even bonded
out to the card edge, let alone to rear panel connections unless its in the
actual monitor plug, and this monitor has no speakers. So the first thing is
to restore all the audio signal steering to the Audigy-2 (sb400) sound card.
That section of my /etc/modprobe.conf:
options snd cards_limit=8 <-new after f10 upgrade
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-1 snd-hda-intel
options snd-hda-intel index=2
alias snd-card-2 snd-hda-intel
options snd-hda-intel index=2
alias snd-card-7 snd-usb-audio <-new after F10 upgrade
options snd-usb-audio index=7 <-also new, I didn't add these.
I also had entries for the motherboard audio, which apparently didn't survive
On a startx, pulseaudio says it can't do something and will default to the
intel HDA, then fades away before I can memorize what it offers for the
reason, so I assume that is where all my missing system sounds are going.
I don't even know where to start. Help?

Thanks for your reply
I´m aware of that. Thing is that, after downloading and having tried to install
both F9 and F10 several times, I´ve ended up with no more than hangups.
I´ll try CentOS or maybe Debian

By the way, your browser sends some information about your system and
even language you're using on it in a special header. My favourite
Fedora' browser - lynx - doesn't send it. Because of that I can't browse
some pages. Error message on them says: `Sorry. Probably you're robot!`.
I am planning to build a cluster based in Linux. This cluster will
have a master node and some slave
nodes. I would like to boot the cluster from the master node and, if
possible to power/up/down the slaves from the master.
Since I´m considering Fedora 8 as the linux version to use, I woud
like to find updated information on how to do this (yes, you´ve
guessed it, I´m not an expert linux administrator).
any help will be greatly appreciated
