Ubuntu :: Audio CD Extractor And VBR Parameters?
Mar 11, 2010
A couple of weeks ago I installed Karmic. In previous options in Audio CD Extractor I modified a string in the "edit preferences" to set the variable bit rate for MP3 ripping. Specically the option "VBR=4" (Lame New Algorthym) However, I now notice that the "VBR=" option is no longer there!
I've searched around and read some indications that using a newer realease of Lame this is no longer necessary. But its a bit unclear to me. Do I need to insert VBR=4 or not? and if I do anyway will it affect anything?

I'm trying to extract files off of an audio CD using the program that came with Ubuntu. In the preferences I set the format to FLAC but when it's done and I open up the file manager, all the files are mp3. When I try to play the file with Songbird it tells me it can't read the codec. What's going on? I've extracted the music off of CDs before.

I'm using Sound Juicer 2.31.6 to turn CD Audio into digital format for my portable digital audio player.I put in the CD into my disc drive, load up Sound Juicer. I find the track listings on Music Brainz, after having MusicBrainz search FreeDB. But how do I import the track titles into SoundJuicer? I tried "Re-read disc" after entering the name and album exactly as it appears in MusicBrainz, but that doesn't help. It still says "Could not find Unknown Title by Unknown Artist".

i have an hp pavilion dv7 and am using f13 64bit. my laptop has a built in woofer underneath that i have never been able to get to work. after the latest kernel update today my laptop now has woofer sound. there must be some new support for my laptops audio card. the problem is that it is a little overbearing. how can i a) disable this feature b) tweak the parameters like crossover frequency or gain? edit: i checked the changelog for 2.6.34 and couldn't find any info on any new audio support features.

I've recently got a problem. I've installed projectM, the pulse audio version. It worked fine until a couple of days. I noticed, that the visualization isn't synchron with the music. Then I opened pulse audio to check the volume controls. The blue bars showing the intensity of the loudness don't move at all, it's all gray. ProjectM can't analyze the music and therefor cannot visualize correctly.

I download a lot of files that have been compressed into separate pieces by winrar, so that a 4gb file will be shown as dozen or so 93mb peices. In windows, using winrar, extracting them was rather easy but in Kubuntu whatever default program is being used throws a fit. In a perfect world I would want to get a open source alternative from synaptic, alternatively anything I can download in RPM I can eventually figure out. I want to avoid trying to get winrar working under wine.

Bottom line first: Is there a GUI or otherwise friendly tool to modify the kernel parameters? One that will give help on a highlighted parameters?
Now as to my reason for this question:
In preparing for an Informix installation, I may need to change some kernel parameters. I could follow the advice of G�rard BIGOT from a couple of years ago at this URL. However, messing with the kernel this way, by directly editing /etc/sysctl.conf, is a bit scary. I have already backed up the current one and started editing according the Informix machine notes. However, I have commented out my new settings. [:Chicken]
The scariest aspect of this is that the notes recommend settings to kernel parameters that I do not find in /proc/sys/kernel. for example, it recommends setting SHMMIN to 1 but when I can /proc/sys.kernel/shmmin, there is no such file. (I did find shmmax.) Similarly for the very logical shmseg (max number of shared memory segments) - not found. I am afraid to add these into sysctl.conf if the equivalent pseudo-files don't exist.
Additional question: Where [on-line] do I find all kernel parameters documented? This is so that I am more certain of what I am doing instead of relying on my memory. For example, I don't recall the names of the parameters that control Kernel-Asynchronous I/O (KAIO) events.

How do I pass file names as parameters to the shell through a script? I have installed 'wipe' from the repos and it is a shell based app. so I made a shellscript and put it in my script folder.
the normal usage of wipe is 'wipe -q /path/to/file' so if I were to make a shell script, right click on the file in question, and run the script on it, how to I permit the shell to wipe that file only, in other words pass it as a parameter. I think on windows it was the use of %1, such as. 'wipe -q %1' for example, which was simple enough. how to I achieve this with bash?

Ubuntu 10.04 Gnome IBM Thinkpad 600e.I am trying to get sound going in my 600e which has the wrong chips in the sound card. I found some notes from 2008 that said in one of the steps to add the following to my kernel boot parameters: noapci nolapci notsc acpi=off pnpbios=off pci=noacpi
It said to hit the Esc key when I see the Grub Count on boot up to get into the kernel boot parameter's editor. However, I am not seeing any Grub Count and pressing the Esc key every second during boot up doesn't seem to get me there either. I have been searching for how to edit the boot parameters but no luck so far.

We're using 10.10-server. We are trying to make grub boot changes permanent. I've already looked at thread [URL]. We updated /etc/default/grub, and update-grub propagates those changes into /boot/grub/grub.cfg, but not into menu.lst. It appears to use menu.lst as the source at boot, so our change doesn't show up as a linux parm.

I have a mental block whenever I'm confronted with anything to do with grub2. Changing things in menu.lst was SO much simpler....
I want to include the command 'acpi=off' - but where do I put it? Can I change the detail of an existing grub entry in this way, or do I have to create a complete custom menu entry in grub.d and include it in that?

Old Toshiba laptop model A30 -- tried various installs 8.04/9.04/9.10. They all hung trying to boot the install disks after the initial few screens. Finally, I got 9.10 to install, dual booting XP and 9.10 by choosing F6 from the initial menu, and putting an X beside:
ACPI=off
noapic
nolapc
edd=on
nodmaid
and then hitting escape.But, after the install, I couldn't boot 9.10 from grub as it hangs after about 30 seconds of trying. The live CD would not work without the above parameters being set as described above, but does work with them set! I need those same parameters passed to grub at 9.10 boot time, but I can't figure out how to do that. I've had many successful installs of Ubuntu across a number of desktops and laptops, but I never had to deal with the guts of grub before. It all just worked.

My project for today has been setting up a web server. I was given a old computer with a Pentium 4 processor; 512mb of RAM, and a 42gig hard drive.I was reading over some guides and I came across this guide. It is very self explanatory; however I am having issues with my configuration files within Apache and my firewall (shorewall).I am focusing on web security. I don't even want to web edit until I know it is "lock-down" secure. In Apache are some supposed settings called Server Tokens and SeverSignature. I can't locate these files in my apache2.conf unfortunately.Here is what is posted to me in the config:
Code:
#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
[code]....
Then press Control-O and Control-X. Your firewall is now configured to only accept HTTP and SSH traffic.I couldn't get that line of code to run. I've been all over the Ubuntu forums, google, Apache 2.2...

I have a Java program (minecraft server) that needs to be run from the command line. The code is:
Code:
java -Xmx512M -Xms512M -jar minecraft_server.jar nogui
To make life easy (i've got the java file in a folder on the desktop) I want to have a shortcut (or similar) sitting on the desktop. I've tried
Code:
ln 'java -Xmx512M -Xms512M -jar minecraft_server.jar nogui' ./../minesraftserver
with single and double quotes but my unix command line skills are pretty basic and this is obviously incorrect.

I have a strange problem with RHEL4.7, with kernel 2.6.9-78.
I cannot set any kernel parameters by editing sysctl.conf file and run sysctl -p, everytime the old value appears, while it was possible before.
I tried to edit files under /proc by using vi when trying to save it gives me: E667: Fsync failed!
While echo 1>/proc/sys/net/ipv4/ip_forward also cannot edit the file.
Also I mounted proc device on another mount point:
# mount -t proc proc /mnt

Specifically I'm trying to run xmacro from within a c program. If I were to run it from the terminal I would do it along the lines of Code: xmacroplay :0.0 < script_file.txt, but I want to run it from my c program. I'm fine with my c program running it from the terminal if that's possible and easier but I'm guessing there must be a better way.

I want to change parameters of a RED queue during the simulation but it seems that some parameters can be modified only before starting the simulation, not dynamically, while the simulation is in progress. For example the following subroutines works before $ns run command but it do not change the behavior of the queue during the simulation( I want to change maxthresh_ and thresh_ after $ns
run command): Code: proc setREDParameters { redQueue MINth MAXth PER_MaxP Wq } {
$redQueue set thresh_ $MINth
$redQueue set maxthresh_ $MAXth

Just installed squeeze from previous Lenny and am having problems. With Lenny, for the tv card, needed: the modudule saa7134 card=54 tuner=78, i.e. had to give it the card= tuner= stuff - it could not autodetect that bit. Squeeze appears the same:
Code:
[ 5.055340] saa7133[0]: subsystem: 17de:7253, board: UNKNOWN/GENERIC [card=0,autodetected]
So, question, how do I give it the module options? - the problem is 'modconf' will not unload the saa7134 module because it says it is in use, even though the TV is not being used. And # modprobe saa7134 card=54 tuner=78 does not appear to do anything - it does not say anything but nothing shows on dmesg. Here is how tvtime, a fairly fool proof tv player, behaves:
Code:
root@fido:/home/lugo# tvtime
Running tvtime 1.0.2.
Reading configuration from /etc/tvtime/tvtime.xml
Reading configuration from /root/.tvtime/tvtime.xml
mixer: Can't open device /dev/mixer, mixer volume and mute unavailable.
