UFRaw vs RawTherapee vs Darktable
I just started shooting with my Nikon D700. Doing it in RAW (and jpeg). Using desktop OS Ubuntu 11.10. And don't know yet which program is the best: UFRaw vs RawTherapee vs Darktable?
Any one who can push me in the right (best) direction, please?

Ubuntu and Firefox Downgrades
Oh great LJGenie that knows how to edit everything in Ubuntu,
I have two questions:
1) How can I downgrade to Maverick Meerkat? I upgraded to Maverick Meerkat from Lucid Lynx and then to Natty Narwhal from Maverick Meerkat on my laptop because I though, "Oh, I should probably upgrade" seeing that they are already working on the "O" version. However, I hate the layout of Natty Narwhal. I am also having tons of problems with things loading on Natty Narwhal. They do not start. The title bars turn gray and the rest of the screens turn white. This especially happens when I try to download any programs. The download dialogue box in firefox doesn't load. If it happens to load, the installer does not load. Is there an easy way to download or do I have to do a fresh install? Is Maverick Meerkat like Lucid Lynx or should I go back to Lucid Lynx? Also, where do I get the old versions?
2) Is it possible to run a newer and an older version of firefox? It is nice to have the newer version, but sometimes I work on ChaCha and it needs a version of firefox that is under version 4 as the toolbar needed is not compatible with the higher versions of firefox. I can use the lower versions, but it would be nice to use the high versions other than when I work on ChaCha.

how to converse properly!!!
People no longer how to converse in a proper manner. I am so utterly fucking tired of trying to talk to you people...
Every time I share a story or express how a situation caused me to feel, you all automatically bring up something from your own experiences with no regard for the possibility that I might want to go further into it...
This applies to almost everyone I know. I think it would be healthy if everyone practiced this conversational format with everyone. It will be far more rewarding for both parties involved.
Essentially... The way real conversations work is there is supposed to be that one party expresses an experience they had.
The other party (if interested) expresses interest and asks to hear more about it. THEN (if appropriate!) the listening party inquires as to how the speaking party feels about this. Things such as what they felt during this time. It is also fairly common to inquire as to what kind of impact this has had on other situations in life.
When the listening party feels as though the speaker has expressed enough to seem complete, the listener can then relate to their story with their own experience.
THIS is how a CONVERSATION works.
Thank you. :D

How to fix Shockwave Flash plugin crashing in Chromium browser under Ubuntu
THE BUG: Upgraded Chromium browser on ubuntu shows "The following plug-in has crashed: Shockwave Flash" when you go to youtube.
Previously I posted on how to downgrade your version of Adobe Flash Plugin
to make it work with the Chromium browser
Well with the newest update it now WARNS YOU each time if you try to use the older version of the plugin. And you have to click to accept the warning that you are using the older version of the plugin.
So I found another work around to enable the Chromium browser to be able to play youtube videos.
* 1- Open FIREFOX and go to Youtube. Select any video and when it loads and starts playing RIGHT CLICK inside the video to get a menu and select "Settings".
* 2- In the settings window you should see a popup window labeled "Adobe Flash Player Settings" like this.
* 3- UNCHECK the setting for hardware acceleration.
Now go open up a new CHROMIUM window and youtube videos should play fine.

About Tux and Admin. Some support needed!
Here is a picture, that i made from plasticine.
There is a shaman drum on the wall, necessary atribute of ukrainian and russian admins. They use it when system is broken, and standard methods for repair is't working. Also it frequently applies, when you need to set up some drivers on Linux :)
Abot cat: it is cat! But something strange stands near it. Our admins love cats!
Tux with Admin are celebrating birthday of some local hoster: they drinking champagne from mugs and eating sausage with cake.
That picture was made for challange, if you like it, please support me there: http://hostpro.ua/konkurs/work.html?user=125
Just click twitter or facebook icon, login by widget and push orange button under image (it appears after login).
I will be glad to hear something special about Linux admins in your country!

I'm looking to build a server to protect my data at home. I'm wondering if anybody has experience with the debate I'm having.
I'm going to use Ubuntu to build a software RAID 6 system. I was wondering about adding disks to the array afterward. Is it a real pain to do? And is it safe? I want to get my server built soon but buying the hard drives I need is going to be expensive. Should I save up the money and buy all of my drives at once or is it relatively simple to create the array with, say, 5 disks and then add one at a time as my storage needs increase?
I don't mind if it takes time to rebuild the array. I can let it do the calculations overnight and when I'm at work but is it going to put my data at risk if I add a hard dive every few months and have to rebuild the array each time?

Y'know, after more than a week of pondering, I'm still perplexed by appStream
and its possible effects.
"Developers from RedHat, Fedora, Debian, Ubuntu, openSUSE, Mandriva and Mageia got together last week at the SUSE office in Nürnberg to discuss how they might implement a universal application installer they are referring to as an Application Store. "
Sure I've got thoughts on the matter, but I haven't really been able to form an opinion either way as of yet. I'm interested in others perceptions, especially of those who were around the first time the concept was presented ?
(note: there's also a video of the meeting
//Update: from a (poorly, poorly written!) article
Current Mood: awake
"Hopefully, if Canonical agrees to drop the CLA [contributor license agreement] from the Ubuntu Software Center, then we can just make a few changes and all use that," says Hughes. "If they refuse to drop the CLA, then it's impossible to ship in GNOME, and we'll have to write our own front end client. That would put the project back 18 months or so, I would estimate, and be a real waste of everyone's time," .

Does anyone know if the new French anti-piracy tax on all non-microsoft tablet pcs extends to tablets without a pre-installed OS? Or, seeing as this law seems to be derived from and targeted towards mobile devices, is it applicable to a tablet with a full desktop GNU/Linux distribution installed? Citations are greatly appreciated :)

Linux Network Server
Not specifically a Linux question, but I can think of no better group of people to ask this...
The time has come to decommission my more than 10 year old network server, still running Slack 9, no less. Oh Slackware, we've had so much fun together :). However, the hardware started failing in the poor old thing, so I'm preparing for a slow migration to a new server, before this becomes an emergency 1 night long project :).
Anyways, this box has 3 network cards in it and it's responsible for all of the routing and network related services in the house (routing, firewall, squid, apache, ftp, ssh tunneling relay, etc).
Since I'm replacing the whole system, I decided to look into dedicated network server systems, but I have no experience with that sort of hardware at all, so I would love any suggestions you may have.
The server must satisfy the following:
- 3 NICs
- Cheaper than $400
- Kind of like this, actually: http://linitx.com/viewproduct.php?prodid=11484

The latest story in my doomed attempt to understand Linux...
To set the scene, I am working with an eleven-year-old Compaq Armada 7400 laptop (£3,437 when new...
) which I have recently tried to revive by trashing the Windoze XP Pro installation which was already installed when I bought it (£200, end of 2004), and switching to Xubuntu, on recommendation of a Linux-head I've known for years and who knows how to get Slackware to work. He's always told me Xubuntu is the one to go for on an old or slow machine, due to the lower system requirements of the XFCE desktop.
With ridiculously low resources available (a 10 GB hard drive, Pentium II 300 MHz processor, 128 MB RAM - which was probably brilliant for a laptop in 1999), I gave Xubuntu 10.10 a shot - using the alternative CD, as the system specs were too low to run the live CD - and it was as if time had frozen on it. So that was junked and I tried Xubuntu 9.04 instead - the oldest version I had easy access to. That worked... just. While searching the all-knowing oracle
I found Lubuntu, which I'd never heard of before - so I gave that a go. Live CD only, but it worked, and what a pleasant surprise, it runs... really quite smoothly!
Only one problem, though: the screen. Whether it was either of the versions of Xubuntu I tried, or the Lubuntu live CD, or the permanent installation of Lubuntu 10.10 I've got going now, it cannot get the screen resolution right. It's a nasty 800×600 screen given as maximum, when I know full well that the old Windoze installation had it set at 1024×768, which is the actual pixel resolution.
What I've tried so far is advice from a couple of troubleshooting guides (1) (2)
which mention using the xrandr command. Here's the raw output:xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 240, current 800 x 600, maximum 800 x 600
default connected 800x600+0+0 0mm x 0mm
800x600 60.0* 56.0
400x300 60.0 56.0
I notice that the mode is called "default" rather than LVDS or LVDS1 or something similar that indicates a laptop monitor. Whether this has anything to do with failing to get the size of the gamma or not I have no idea. Still, I pressed on:$ cvt 1024 768
Output:# 1024x768 59.92 Hz (CVT 0.79M3) hsync: 47.82 kHz; pclk: 63.50 MHz
Modeline "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
Which then goes into xrandr:$ xrandr --newmode "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
And it all comes crashing down again:xrandr: Failed to get size of gamma for output default
...and that's where the advice runs out, and as I have yet to understand what a single error message actually means
, here is where I have to give up.
(1) Is it supposed to be showing an LVDS or LVDS1 screen type rather than "default", and
(2) Is there any way to make it not
fail to get the size of the gamma?
Once that's sorted, then
I can have a go at putting it into .xprofile...
...and did I mention that the "delete the ~/.config/monitors.xml" trick won't work, because the file isn't there anyway?

The sorry state of software
Why is it that no one can make a music management application which can correctly sync with mass storage type players? This is not exactly rocket surgery.
- (And I realize that this is actually an Ubuntu bug) – I plug in my iPod3G running Rockbox via Firewire, which kicks it into disk mode and causes it to charge, and it automounts. However, the hal doesn’t see it as an audio player, so the various apps which use the hal (Rockbox, banshee, etc.) don’t see it. Of course, I can plug it in via USB and it works, but won’t charge, and I have to manually kick it into disk mode.
- Most of the apps allow you to drag and drop the playlists on to the player, and it will copy all the files there, but in most cases it will not do what it should and copy the playlist too. This would be ideal – drag and drop a pile of playlists, all the songs get populated and the playlists get stuck in the right spot on the device, and re-homed to work correctly with the relative pathnames of said device.
- Some apps (most notably banshee) actually support some semblance of sync. However, it only seems to handle syncing the whole library (which is too large) or a single playlist (which is too limited).
That said, this falls into the “put up or shut up” file, so I’ve written a perl script which takes a list of .m3u files and does the right thing. I plan to put it up on my website – however. after I wrote it, I realized I could extend it to have more functionality. Specifically:
- sync – well, it does this already
- rm – remove files in the playlist from the target (note, you’ll want to do an rm, then a sync to ensure that any files deleted by the rm get put back by the sync)
- du – disk usage of each playlist and aggregate usage of all of them (with appropriate accounting for the same file in multiple playlists, of course).. Might need to extend this to also account for the ones already on disk.
Uploaded initial version of the script to github

Sounds issues on Ubuntu
My laptop completely crashed, so I opted for a desktop for many reasons. It came with Windows 7, and after many tries of installing Ubuntu, I finally got it installed about the fifth time.
Anyway, my sound was working fine at first. Then, it stopped working on Ubuntu through the speakers, but it would play through the headphones.
I know these two things shouldn't have affected things, but just so you know, my mom had logged onto Windows and my sister was using the headphones, but she had muted them (they have a volume and mute on them) so she could hear something on the television.
When I came to use my computer again, the sound didn't work through the headphoens or through the speakers. I've tried every combination that I have in my sound options both with and without the headphones, but sounds never play.
I am using Ubuntu 10.10 (Maverick Meerkat). I know my Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Can anybody tell me what I need to do in order to fix this problem?

Virtual domains for Postfix MTA + Dovecot POP3 + Cyrus SASL + Fetchmail + Procmail MDA
On SuSe SLES 10SP3, using Postfix as an MTA, created a few virtual mailboxes.
Each box authenticates via POP3 to Maildir format in /home/vmail/%d/%u/Maildir/ .
If this matters, Cyrus is being used for SMTP SASL authentication.
These mailboxes are verified as fully functional.
Created a .fetchmailrc for fetchmail to pull mail from a MS BPOS Exchange 2007 cloud server, then forward to said postfix virtual mailbox.
Here is the issue: Fetchmail's pulled mail should forward via procmail toward virtual domains in Postfix. However, procmail takes issue with virtual domains, and refuses forwarding.
(Explanation of procmail's limitation available here: http://partmaps.org/era/procmail/mini-faq.html#virtdom
As an alternative, removed virtual domains in postfix's main.cf, using local linux account pam authentication. Forwarding via procmail and fetchmail toward a single local linux accounts works, will not work for multiple local accounts.
In looking for alernatives, are maildrop
good solutions for replacing fetchmail and procmail? Anyone have experience forwarding fetchmail via procmail toward multiple local server accounts? Remote accounts will not suffice for this scenario.
Attached both .fetchmailrc and .procmailrc (real sslfingerprint and account removed):.fetchmailrc
# initial setup
set postmaster "localaccount"
set daemon 600
# must provide ssl fingerprint for self signed ssl certificates
# fetchmail -d0 -vk red001.mail.microsoftonline.com
# accounts to poll
poll "red001.mail.microsoftonline.com" protocol POP3 uidl auth password
user 'firstname.lastname@example.org' there with password 'password' is localaccount here options ssl

Rant on /etc/default
In debian, /etc/default/ is a directory of mostly empty (or very small)
files. The way it is meant to work is that each /etc/init.d/foobar
script first sources /etc/default/foobar before starting/stopping the
foobar service. The purpose of the file is to provide extra options for
when starting the service, or override certain aspects of the service's
startup. A common way this is used is so a package can go ahead and
install the whole /etc/rc.d/ structure for automatic startup/shutdown,
but not actually start it until the user edits /etc/default/foobar to
really enable it by setting "FOOBAR_ENABLED=1". This way you don't have
to worry about daemons being automatically started when the user hasn't
yet configured them.
-- ( one of the half decent explanations I found on the internet about it)
To do non standard shit like that BREAKS things. In my case, it made it that the UPS utility wasn't starting ( You know, the one that auto-shutdowns the server in case of power failures? Yeah.. that one). Because the variable ISCONFIGURED was equal to "no". No, there was no note of this "unable to start service" business in /var/log/messages.
There's already a method to not start services, and that's to have a K99 ( or KXXutility, or simply nothing!) in front of the link in /etc/rc.d because then, it's OBVIOUS why the service is not starting. All that you stupid fools are doing is adding YET another layer of complexity that breaks things. Like, I understand why some of those features are even $something_good , but you guys are breaking shit trying to improve things, and that's really really dumb.
And don't get me started on if-up. Current Mood: annoyed
