Ubuntu Multimedia :: Which As Used Extensively In Production Environments?
Apr 29, 2010
I imagine this question is hard to answer and will get very few takers but I am hoping someone will be able to help. Has anyone ever done a cost analysis of video production facilities that use Linux vs Windows vs OS X?
My company use Final Cut on OS X to edit video, Photoshop on Windows or OS X for photo editing and Nuke on Linux for visual effects composting. We have multiple computers running in this configuration but have not looked deeply into how to achieve maximum value for our money.
Mac's can cost up to four times as much as a comparable Windows machine but save on electricity over the course of their life and have better software for our workflow. Linux machines are even cheaper as they use the same electricity as Windows but the OS is free. Unfortunately, Linux does not have Photoshop, or a good video editor. Gimp does not support opening PSD files, which as used extensively in production environments. Basically my question is has there been any studies done on this subject?

I have installed Kubuntu 9.10 on my old laptop, and tho the graphics are nice, the performance is not spectacular.
Here's my system - humble but not too lousy either
CPU: Intel Pentium M 1.80GHz
Memory: 512MB
Graphics controller: ATI RV350 (Mobility Radeon 9600 M10)
So, I thought I'd like to test out other desktop environment, without too much bells and whistles, I am considering Xfce.
But I lack deeper Linux knowledge in order to complete this without messing up my system.
1) how to install the secondary DE properly, without hurting the existing DE?
2) How much duplication takes place, when one installs the secondary DE. Ie, will I need to reinstall, say, Firefox for the other DE? I guess KDE and Xfce definitely have different desktop managers, network managers, etc, so there will be some overhead because of this. Will I be able to install new apps and enjoy using them in both DEs, will their configs be the same?

I have both xmonad and Gnome installed and tend to switch between them quite often. Normally, I need to log out and log back in which is starting to become annoying because I need to open any running applications again.I have tried using "Switch User", but it doesn't work. I go to the switching screen when I am logged into Gnome and log in again after selecting Xmonad, but it brings me back to my Gnome session.
So is there any way to log in as the same user with two different desktop environments at the same time?

currently i run both KDE and Ubuntu Unity 11.04 on my machine. I have encountered a little problem when switching desktop environments. With KDE, i prefer to use KWin as my windows manager (since i find it highly polished), and with Unity, compiz (not by choice). The problem is that if i don't switch the windows manager to compiz before switching over to unity, all hell breaks loose. Same with switching over from Unity to KDE.
The only solution i have found is to switch to Classic Ubuntu. and use the compiz fusion icon to select the windows manager in order to avoid any problems.
when i log onto the either KDE or Unity, how can i load the correct desktop environment in case it crashes (which it has)?
Note: this has also become a concern to me because of 11.10 removing the classic gnome. If the proper window manger can be loaded before entering the preferred desktop environment KDE, Gnome3 or Unity,

I'm trying to get Gnome 3 to work on 11.04 under virtualbox (3D acceleration enabled) but I get the message that "it can't load session gnome" when I try to log in. The same message appears when I try to do this on an EC2 instance. Please let me know if someone got it to work on EC2.

I'm finalizing the the dual-boot addition that I recently completed. I've added lubuntu to the LT3114u Netbook that I use. That's done, now I'm migrating my user environment back from the Cygwin one that I've been using on Windoze, as of late. One of features that's been useful has been the global environment management possible with the windoze UI functions. As I coded my emacs environment while 'over there' (windoze side), I included a check for the lisp library repository path environment variable EMACSLOADPATH. It is globally available when one logs in, and does not get set in any user scripts, or dot files any to do with CYGWIN or emacs.
While it has been easy enough to set EMACSLOADPATH for the login shell environment, via .bashrc, .profile, and system wide via /etc/profile, I have not been able to have '/usr/bin/emacs23' have EMACSLOADPATH set when invoked via the LXDE UI. Thus, it would appear that emacs is not being initialized with the same environment that any of the shells are (old school?). Thus, what is it that one must update in order to have GNU emacs initialized with the same environment variables as bash? Or, put another way, why aren't the environment variable defined in /etc/profile, ~/.bashrc and/or ~/.profile ending up in the initialized environment upon invocation of emacs23 on lubuntu Linux?

I have two desktop environments installed on my Fedora pc. Here it is
[Code]...
Is it still possible to install other desktop environments despite already having installed KDE and GNOME? If I happen to install other desktop environments such as XFCE, LXDE, CDE, EDE, UDE, will I be able to use one particular environment by disabling the rest whenever needed

we have here a few openSUSE-machines (some 11.1 and 11.2) which mounts their /home from a NFS-Server and imports the users via NIS. I now wanted to use X-Forwarding via SSH, but that doesn't work with NIS-Users.On my machine I use Gnome and my XAUTHORITY-Variable points to /var/run/gdm/auth-for-bup_deg-E3TMSz/database
Why isn't the default ~/.Xauthority-File used for my cookies? What do I have to change to get X-Forwarding in my Setup running?

well I switched from windows several years ago and never looked back. I wanted to use fedora (and I did for a while) but ended up using ubuntu studio (actually ubuntu with selected studio components) and to be fair it has worked out well. the thing is I am looking to keep my server skills up to date and I know at this time redhat is king and fedora has most of the stuff I need to keep current (files in same places, yum/rmp vs apt-get) for that elusive linux job I am looking for. but I need a real time kernel, jack, ardour, hydrogen and other assorted open source packages because, well because that is my interest. so...
1) Are these packages available in fedora via yum (I don't want to maintain tar packages)
2) Is there a real time kernel as well from yum?
3) kvm/qemu virtual machines did not work with the rt kernel on ubuntu 9.04 but DID in fact work on ubuntu 9.10. Has anyone used the rt kernel and run kvm/qemu on fedora? cause if I cant have a few vm's (opensolaris, centos and xp to be exact) I cannot come back.
ubuntu is nice but after a year I still keep starting to type yum install vs apt-get so I guess fedora never really left me... oh I should mention my computer is 64 bit...

I assume that the maturity of UFW is irrelevant because in the end it is just a front end for iptables...
But just in case, is UFW mature enough for production use on a web server?

I have had a look round and so far the consensus seems to be that you cannot upgrade a 11.1 system to 11.4, is that right? I have a small server running for a charity, it runs Oracle Apex, Kerio Connect and acts as a file server using Samba. It has KDE4 on it. The reason for upgrading would be to continue to receive updates for the OS.
Has anyone any advice on where to start with this or whether it is a dead loss?

This is my first time to set up a production web server and I got some few questions on our migrations:
1. Our website from the Web Hosting company already gaining 5000000 hits/month and 35000 unique visitors/month, problem is we only have 2x4mb dedicated line here in the office and one IBM x3650 m3 for our LAMP, you think guys its enough to handle that kind of traffic if we start moving our web server here in the office?
2. If I register www.example.com to GoDaddy for example, do I still need to setup a DNS (BIND) server on our side?
3. This is my current Apache config:
Apache/2.2.3 (CentOS) DAV/2 mod_fcgid/2.3.6 mod_auth_kerb/5.1 PHP/5.1.6 mod_python/3.2.8 Python/2.4.3 mod_ssl/2.2.3 OpenSSL/0.9.8e-fips-rhel5 mod_perl/2.0.4 Perl/v5.8.8 with PHP eAccelerator.
Anything to share to increase the performance of the web server?

I administer several web hosting (combined with mail relays and other services) production servers under Debian GNU/Linux. I began giving these public services two years ago via three boxes: the first is a gateway which controls traffic via iptables (it's attached to a DSL modem) between a public subnet (the DMZ) and a local network which connects several workstations. In the DMZ subnet I maintain two Pentium-III era boxes, they've grown in services since I set them up. Actually, I think I should buy new ones, but, you know, I want to save money and lenghten its life.
So, they've grown in data hosted, but I've never implemented a resilent backup system. I've set up some rsync tasks sheduled via cron jobs to copy the entire UNIX file system in each of the DMZ boxes, but I'd like to be prepared before an unexpected "real" crash of some HDD, I mean, some problem that renders a disk unusable.
AFAIK, sysadmins sync entire HD backups which are capable of recovering a system via swapping the unusable unit with the backup unit. Maybe the best fashion is to implement a RAID mirroring the unit, I'm I right? So, keeping my systems as they are, I mean, capable of using 4 parallel ATA units, what would you do? Use dump, rsync or some other way to have an operational second unit with an exact copy in a bootable second drive, in order to quickly swap it if the main unit fails?
Comes to my mind to partition a second unit (so making it bootable) and backup daily via rsync only those parts of the unix file system hierarchy which are necessary to boot a system properly. What do you think about this workaround?

i have a production server running RHEL 4.0 with 2x146 GB on a RAID 1 with OS and another storage with 2x300 GB on a RAID 1 with the application, it's the database and application.
No LVM was installing and configured before, and now the second array with mirror of 300 GB is running out of disk.
1. i have 2 new hdd to build another mirror 2 x 300GB.
how can i create a LVM to star using the vgextend anytime i need it?

I'm using Apache as a web server and mod_ssl to handle my certs. Everything was working fine on Fedora 11 running 0.9.8x of openssl until I updated to 12. Version 1.0.0beta4 of open ssl is full of bugs. It is basically incompatible with .net and php's implementation of SSL. Running wireshark actually shows it fails at handshake stages...
I'm not here to report the bugs relating to openssl but can somebody please explain why there is an unstable version of openssl in Fedora 12 as standard?

We have several production machines serving our static content. I want an automatic operation where I would only need to upload to one of them and it will get replicated/mirrored to all machines.Either that or distribute automatically from local source to all machines. First option is obviously better since all machines reside on same LAN and remote to our office.
Another feature I am looking for is to get a full report on what got transferred and if any problems occurred immediately (since usually these deployments can mean downtime for us). Looking around I saw rsync.Using CentOS 5.4-5.5 btw.

i have problems with my failover machines and cant locate the cause. The last update is quite some time ago.So will it hurt my configuration when I do an yum-update? I have 5 Xen VM on each machine, also they replicate with drbd and heartbeat. Can I just update the dom0 and leave the VM untouched inside?

- Off a vanilla F11 livecd install, I stuck a 3 at the end of my grub line to boot into runlevel 3. I have been doing this for as long as I can remember (since Fedora 3). However now it seems to break and gives me a GRUB error. I press e to edit, and delete the 3. BUt it still throws and error?!?!?!?! Has this facility (ie sticking a number at the end of the grub line) been changed and why is my grub line now broken even though I've gone back and deleted the 3?
- If I install Fedora 12 beta now, will yum take me all the way into production when it goes live (assuming no killer bugs encountered), I'm guessing thats a yes?
