[00:00] <len-1304> 10.7 ms latency on jack, more on the stream itself (maybe .5 sec)
[00:08] <Lump|AFK> heya len-1304 how was work?
[00:10] <len-1304> Work was ok... a bit heavy, but no over time.
[00:10] <Lump|AFK> meanwhile, i am again having meterbridge, jack rack idjc issue
[00:11] <Lump|AFK> doing exactly what we did the other night exceopt trying to get the ppm metere into the mix
[00:11] <len-1304> idjc uses a lot of cpu.
[00:11] <lumpy> i can't get the meters to move tonight
[00:11] <len-1304> Even with no jackrack.
[00:12] <len-1304> Could be I am running latency to low for this system
[00:12] <lumpy> i know you will get it
[00:13] <len-1304> Sometimes when switching workspaces I get xruns as xorg uses lots of cpu redrawing :)
[00:13] <len-1304> Sometimes it is ok too.
[00:15] <len-1304> idjc is using 60%, pulse 31%, audacious 12.8%, another idjc at 10%, xorg at 5% and jack is 4%
[00:16] <len-1304> There is no cpu governor as this MB does not support it.
[00:19] <len-1304> I think if I could get pulse down to 2 channels instead of 12/10 the cpu use would go down too.
[00:27]  * lumpy bangs head repeatedly off desk... picks up cinder block to assist the process with whaps to the back of the head...
[00:27] <lumpy> found my sf issue
[00:28] <len-1304> :) lots of description.
[00:28] <lumpy> for some reason, the wrong input was selected for capture
[00:28] <len-1304> CPU goes way down when I use the internal player.
[00:28] <lumpy> i didn't change it but that was it
[00:28] <len-1304> Wrong port would do it.
[00:29] <lumpy> well, i am trying to get line in --> ppm meter --> jackrack --> ppm --> idjc dialed in tonight
[00:29] <lumpy> with da nice n' pertty meters you made me hip to
[00:29] <lumpy> brb though... need coca-cola
[01:00] <lumpy> so i got it as above
[01:00] <lumpy> 21% cpu usage
[01:00] <len-1304> Ok.
[01:01] <len-1304> I think you are using a higher latency than I am though.... and no pulse.
[01:04] <len-1304> Jack says 20%, but top says idjc is using 60%.
[01:05] <len-1304> Also, I have the streamer and jack set to 48k, so idjc may be doin more work resampling.
[01:08] <lumpy> meterbridge 10, idjc (not streaming atm) 10, jackrack 2
[01:08] <lumpy> floating up and down about 3-4 from that
[01:09] <lumpy> oh and thanks for making that meterbridge cli crystal clear
[01:13] <len-1304> Ya, streaming makes a big difference. 20% no streaming, 60% streaming.
[01:15] <lumpy> i am working up to that
[01:15] <len-nb> Anyway, I need to go for a bit... bread prep
[01:16] <lumpy> waiting for the pizza, booze and dancing girls to show up first
[01:16] <lumpy> loading up the cue, once i start, i will be going, with a few breaks till 2 AM my time
[02:01] <lumpy> now streaming
[02:02] <lumpy> 35-45 % total
[06:43] <lumpy> well it is still streaming
[06:43] <lumpy> and doing pretty well
[14:50] <ShapeShifter499> hi
[14:52] <ShapeShifter499> what is the low-latency kernel and do I really need it?   I'm guessing it's for audio and to help minimize lags and issues that may occur for optimal use
[15:15] <zequence> ShapeShifter499: That's right. It makes it possible for you to run an audio server at a lower latency then with -generic
[15:15] <zequence> If you aren't planning on doing any live stuff, like playing a soft synth, you won't need it
[15:16] <ShapeShifter499> zequence, I'm new at all this stuff, big noob, but I did want to try my hand at dubstep and other music
[15:17] <zequence> ShapeShifter499: I'd start with hydrogen, and make some beats
[15:18] <zequence> dub step is a genre, and you don't just jump into that and start making great sounding music. Some things are easy to do, some things may take years to learn
[15:19] <ShapeShifter499> lol I know
[15:19] <zequence> You can use qtractor to control a soft synth too
[15:19] <zequence> hydrogen can either be synced with qtractor, or you just use hydrogen as a drum machine, making the beats with qtractor
[15:20] <zequence> qtractor is a DAW. It handles both midi and audio
[15:20] <ShapeShifter499> zequence, oh when installing, I came across this issue, ubuntustudio-default-settings  conflicted with ubuntustudio-menu, so I went with ubuntustudio-menu, any issues with that? I wasn't sure what was the diff
[15:21] <zequence> ShapeShifter499: Ok. I think -menu is not used anymore
[15:21] <zequence> You should go with -default-settings insteaad
[15:22] <ShapeShifter499> ok
[15:23] <ShapeShifter499> hmm this might mess with vmware
[15:24] <ShapeShifter499> the low-latency kernel, its at 3.5 and I could only get it working with the latest 3.7
[15:25] <zequence> ShapeShifter499: raring has both -generic and -lowlatency, if you want to install those
[15:25] <zequence> -lowlatency is a -generic kernel, but with a couple of different configs
[15:26] <zequence> So, if you can just find the same version, support is equal
[15:26] <zequence> Just make sure to install headers when you need to have a kernel module built
[15:26] <zequence> Why use vmware, when there are free alternatives?
[15:28] <ShapeShifter499> zequence, my friend had a vmware key he let me use, thought I'd try it
[15:33] <ShapeShifter499> zequence, I'll just re-patch vmware with the older 3.5 kernel hack, I already have a windows 7 vm set up and I don't want to risk having it not work in another vm app if I export it
[15:36] <zequence> ShapeShifter499: If I were you, I'd either make a new install for the audio stuff, and keep other system critical stuff separate in its own system. Maybe even another computer
[15:37] <zequence> ..or keeping it on another computer would be the second choice, I meant
[15:41] <ShapeShifter499> zequence, vmware is the only issue app,   is there a lot of issues with the lowlatency kernel?
[15:41] <zequence> ShapeShifter499: As I said, -lowlatency and -generic are the same kernel
[15:42] <zequence> The difference is very small. So small, that you'll hardly ever get into a problem with -lowlatency that you would not get with -generic of the same version as well
[15:42] <ShapeShifter499> ah ok
[15:44] <ShapeShifter499> well time for a reboot into the new kernel, brb
[15:45] <len-1304> ShapeShifter499, The only possible difference is resource use may be higher. Like more battery use.
[15:46] <len-1304> It is different on different machines.
[15:46] <len-1304> My netbook (atom based) shows no difference.
[15:46] <len-1304> But some notebooks do.
[15:53] <ShapeShifter499> back
[15:53] <ShapeShifter499> len-1304, zequence reboot went perfectly
[15:54] <ShapeShifter499> len-1304, zequence vmware even recompiled correctly
[15:54] <ShapeShifter499> uname -r shows I'm on the latest lowlatency kernel
[15:55] <len-1304> kernels seem to have a lot less issues from version to version than a few years ago.
[15:56] <ShapeShifter499> linux rocks
[15:56]  * len-1304 has given up on anything else
[15:56] <zequence> Don't forget GNU and Debian :)
[15:57] <contrapunctus> lmfao
[15:58] <ShapeShifter499> xD
[15:59] <zequence> I'm going to an education where pretty much everyone else is a Windows geek, but me. They're talking about what they like and hate about Win8, Win7, etc. And many are of the opinion that Windows is crap, yet they use it.
[16:00] <contrapunctus> o.o
[16:00] <contrapunctus> I take it they are programmers?
[16:00] <zequence> It's funny that they don't know what it is like, using a system, just like they do, but being totally oblivious to what problems occur on a MS platform
[16:01] <zequence> For them it's like Windows is the center of existence
[16:01] <zequence> It's an education for network technicians.
[16:01] <contrapunctus> It's odd that programmers tend to love Linux and hate Windows, with users it's the other way round :\
[16:02] <contrapunctus> Say, zequence
[16:02] <contrapunctus> Remember that Lilypond package yesterday?
[16:02] <contrapunctus> I installed it
[16:02] <contrapunctus> But no go.
[16:03] <zequence> Do you know why?
[16:03] <contrapunctus> Nils (Laborejo) told me - "I would go for a ppa anyway: https://launchpad.net/ubuntu/+source/lilypond"
[16:03] <contrapunctus> What did he mean by that? That page mentions nothing about no PPA :(
[16:04] <zequence> That's not a PPA. That's the package for Ubuntu
[16:04] <contrapunctus> O.o
[16:04] <zequence> For all the different releases
[16:04] <contrapunctus> So what do I do for the PPA? o.o
[16:04] <zequence> I don't know if there is any PPA that has it
[16:04] <zequence> or, the most up to date version anyway
[16:05] <contrapunctus> Raring repos install, then? ;)
[16:06] <zequence> I think your best bet is either install the .sh installer you downloaded, and figure out how to make it work (read the docs, README, INSTALL, things like that), or install 13.04
[16:06] <contrapunctus> One more thing...since I installed a version of LIlypond by using that script.
[16:06] <zequence> contrapunctus: apt-cache show lilypond | grep Depends
[16:06] <contrapunctus> Is there a way to tell where it's path is?
[16:07] <zequence> contrapunctus: You probably saw it during install. You'll probably see it during uninstall
[16:07] <ShapeShifter499> zequence, I'll do some messing around and googling, thank you for the help
[16:07] <zequence> Could be /opt
[16:07] <zequence> contrapunctus: If you are serious about adding the raring repos temporarily, make sure the dependencies won't mess up your system
[16:08] <zequence> If you're lucky, many of those dependencies are the same on earlier Ubuntu
[16:08] <contrapunctus> Hm
[16:08] <contrapunctus> zequence
[16:08] <contrapunctus> It might be solved if I could find out where the SH file is installed
[16:09] <zequence> It's either /opt/lilypond, or /usr/share/lilypond
[16:09] <contrapunctus> Naw...get this, it says that it will install it IN THE HOME FOLDER :))
[16:09] <zequence> There's also /usr/local/share/..
[16:09] <zequence> Because you didn't run it as root
[16:10] <zequence> Only root can make system installs
[16:10] <contrapunctus> /home/<home folder>/lilypond
[16:10] <contrapunctus> Man that's the first time I've seen something like that :) anyway.
[16:10] <zequence> It's quite common
[16:10] <contrapunctus> Ima try specifying this path for Laborejo then.
[16:10] <zequence> Makes it possible for users with no admin rights to install software in their home folder
[16:11] <zequence> Don't specify any paths. Just install it with a sudo command
[16:11] <contrapunctus> zequence - I installed it yesterday, without sudo.
[16:12] <contrapunctus> I need to specify the path to lilypond in one of Laborejo's config files.
[16:13] <contrapunctus> Oh great, it found it. Now to see if it can finally export as lilypond generated PDF...
[16:14] <contrapunctus> Oh, it worked. :)
[16:16] <contrapunctus> One does need to make sure that filename of the original laborejo file has no hyphens (I saw it getting stuck on a hyphen in the terminal). I removed all hyphens, caps and spaces, just to be sure. Something for nilsge to fix, I guess.
[17:07] <contrapunctus> Guys, anyone know how I can make a bootable image of my current UbuntuStudio 12.04+KXStudio install?
[17:09] <contrapunctus> zequence? o.O
[17:10] <zequence> never tried that, so no idea
[17:13] <zequence> I've only messed a bit with making a live Debian ISO. It's possible to make your own custom ones, from using pretty much anything. There might be some tools to do this
[17:14] <contrapunctus> I've used Remastersys on AVLinux.
[17:14] <contrapunctus> Something similar for Ubuntu?
[17:17] <zequence> no idea
[17:18] <len-1304> contrapunctus, how big is your install?
[17:18] <contrapunctus> No idea, len-1304
[17:19] <contrapunctus> How does one know? O.o
[17:19] <len-1304> If it is small enough, you should be able to copy to a USB stick and install grub on it.
[17:19] <len-1304> df will tell you how much of the partition is in use.
[17:20] <len-1304> du / will tell you what size the files are the -h switch in both cases makes it easier to read :)
[17:20] <zequence> will all the files be properly copied?
[17:20] <len-1304> if you use cp -a yes
[17:21] <len-1304> then do du ~/ -h to find out how big the home dir is as you would not need to copy all the stuff in there.
[17:21] <len-1304> You can subtract the size on the home directory from the size of root.
[17:22] <contrapunctus> My install is 13 GB O.o
[17:22] <len-1304> There are lots of 16G and up USB sticks.
[17:22]  * len-1304 has seen 64g USB sticks
[17:23] <contrapunctus> whoa lolwhat
[17:23] <contrapunctus> 64 GB? O.o
[17:23] <len-1304> 32g is more common though.
[17:23] <len-1304> I paid less than $20 for my 16G stick
[17:25] <contrapunctus> o.o
[17:26] <contrapunctus> This really works?
[17:26] <contrapunctus> len-1304 - How do I install grub?
[17:26] <contrapunctus> (On a stick?)
[17:27] <len-1304> Well... I have not tried it with a USB stick, but I have transferred a system from one drive to the other and installed LILO on the new drive (back before grub showed up)
[17:28] <len-1304> A USB drive (A USB stick shows up as a drive) shows up as an SDA device.
[17:28] <len-1304> So I would install Grub first.
[17:29] <zequence> There's a tool called grub-install, for installing grub. It may be as easy as doing: sudo grub-install /dev/sd*, but I'm not sure
[17:29] <len-1304> Then create the partition and format it, then copy the files over and then configure grub.
[17:29] <zequence> Replace * with the right number
[17:30] <len-1304> Remember to make a swap partition if you are going to be running on a machine without a drive that has one.
[17:33] <contrapunctus> o.o
[17:33] <contrapunctus> Cool.
[17:33] <contrapunctus> I'll give it a shot...when I have a USB flash drive that big :)
[17:34] <contrapunctus> Thanks for the info, len-1304.
[17:34] <len-1304> contrapunctus, Like I said check the size of your home directory, you may not need everything on your drive.
[17:35] <contrapunctus> I don't keep my data in the home dir, if that's what you mean...o.o
[17:35] <len-1304> Ahh.
[17:35] <contrapunctus> It's only got config files :)
[17:35] <len-1304> You may not need to copy you r data files whereever they are then.
[17:38] <contrapunctus> Yeah. :)
[17:38] <contrapunctus> Just the Linux install, to back up.
[17:47] <zequence> I have all my data in a separate partition, from where I've made symbolic links to the home dir
[17:47] <zequence> I use a script to add them each time I do a new install
