len-dtailo, automatic updates... What we turn off in xfce settings only turns off the notification of updates, the actual net traffic to find out if there are any updates still happens so long as cron/anacron is running.05:46
len-dtailo, xchat is now connected to ubuntustudio, ubuntu, #opensourcemusicans and #xubuntu05:49
knomelen-dt, automatically? humm.05:53
len-dtknome, which comment were you commenting on?05:54
knomelen-dt, xchat being connected05:55
ailolen-dt: We should turn off the updates all together, wherever it's done.05:55
len-dtxchat dosen't start automatically.05:56
knomeyes, nontheless. i'm not completely sure about opening with #xubuntu, still05:56
len-dtailo, cron does that and other things05:56
len-dtOk, not sure where to go with it then.05:59
ailolen-dt: /etc/apt/apt.conf.d/10periodic05:59
ailoAPT::Periodic::Update-Package-Lists "1";05:59
ailoShould be "0"05:59
ailoShould be adjustable from the update manager06:00
ailoIf not adjustable from any gui that is preinstalled, we might need to add that to -controls06:00
ailoThere are the other options too06:01
ailoAll of them should be "0"06:01
ailoIf that doesn't take care of it, then I don't know06:01
len-dtfrom the update manager settings in the updates tab, it can be set to never.06:02
ailolen-dt: Sounds good.06:02
len-dt(also daily, weekly etc.06:03
ailoWe should just make 0 default, and let the user change that later, if they want06:03
knomeailo, if you do that though, you probably should mention that somewhere visible :)06:05
ailoknome: We should probably mention it somewhere, but people who are used to multimedia work, especially audio will expect updates to be turned off by default06:06
len-dtunder "care and feeding of UbuntuStudio"?06:06
knomeailo, mmh. but studio isn't just audio, is it? :) i think graphic artists, on the contrary, always want the latest tools..06:06
knome(even if that meant just bugfixed stuff - inkscape is oh so crashy anyway!)06:07
ailoThe only reason to update is if something is not working in the first place06:07
ailoAnd then you do it manually06:07
ailoUpdating is a potential danger06:08
knomechecking for updates will also stop from checking for security updates too06:08
len-dtknome, ailo and I differe on this, I feel just turn cron and friends off while recording and on when not, ailo feels it should just work06:08
ailoThat's important for server people, not multimedia people06:08
knomewait... security is not important for ubuntu studio users?06:08
ailoknome: Give me an example of such an update06:09
len-dtit depends if the net is connected.06:09
ailoThere's no reason to change something that already works06:09
knomeailo, say, a firefox update that fixes a security bug that could damage your data.06:09
ailoIt's still best to have it off by default06:10
knomei don't believe there is much need to justify security updates06:10
ailoI haven't seen a single update that has had that sort of impact on a LTS, other than in theory06:11
ailoOr any release for that matter06:11
ailoAlso, if you want to keep your box tidy and working, you might do as holstein. Keep the same install for years, without updating06:11
ailoGraphics artist might install more often06:12
knomeit's your choice. i'm just giving some insight06:12
knomejust please remember ubuntu studio is just not for audio06:12
knomeif it is, please rename it as ubuntu music studio06:12
ailolen-dt: My view is that if you can do it without modes, why use modes?06:13
ailolen-dt: No reason to add complexity, if not needed06:13
ailoThe less the user needs to worry about the better06:13
len-dtailo, I know, there are two sides... I could argue with myself... and loose06:14
knome"this site says ubuntu receives security and other updates, but i haven't seen a single one... am i insecure?"06:14
knomes'pose that's not worrying :)06:14
ailoFrankly, having updates on Ubuntu Studio seemed unproffesional to me06:15
knomeagain i believe that's from the audio POV?06:15
ailoSuitable for a web browsing computer, but not for a workstation meant to use all of the system performance for only what you are using it for directly06:16
ailoYou don't want popups06:16
ailoIt's better to have manual control instead06:16
knomei'm not saying it should be on all the time06:16
ailoIf someone wants to update, just do it06:16
knomejust make it clear that the updates are really turned off06:16
ailoThe update manager is still there for anyone who wants to use it06:16
ailoFor audio the problem is of course most relevant. You don't want to start recording, and find an automatic update caused clicks in your recording, especially if you can't do retakes06:18
knomeof course06:19
len-dtailo, ok, so why do we run popularity-contest, logrotate? (check out /etc/cron.daily)06:19
ailolen-dt: Don't ask me :)06:19
len-dtAnd there are others.06:19
ailoThe intial configuration should be as good as it can get for any workflow you choose to do06:19
ailoTweaks beyond that should either be for troubleshooting, or for personal preference06:20
ailolen-dt: I've never really had a look at what processes Ubuntu Studio has. I do feel that during Gnome2, the system was very minimal and responsive, having much less bloat than Ubuntu. Since we went for XFCE, I haven't really had the time to investigate. Have only been using user desktops, and haven't gone through the trouble of installing a production machine, as I will need to before this autumn06:22
ailoComputers are a bit faster now, and many things change06:23
len-dtailo, that was my feeling the first time I ever looked at ps x06:23
len-dtailo, Computers are a bit faster, but running more extravagant software negates that.06:24
len-dtubuntu tries to automate everything. It takes cpu cycles06:25
ailolen-dt: Maybe not. Even with high cpu load, you don't nessecarily get any problems. It all depends on what prio the processes have and what they are doing, etc.06:26
ailoLast year, with gnome-shell, or unity, on a standard Ubuntu install, with the -lowlatency, I had no problems. The kernel was a bit more responsive back then too06:27
len-dtailo, one example. rtirq sets priorities... snd first then USB. one user has a PCI sound interface, the other has a USB interface. rtirq is wrong for one of them.06:29
ailoI think you might not have gotten better results with a super minimal desktop, maybe not even without graphics at all06:29
ailolen-dt: Yea. It's not good if it causes problems.06:30
ailoAs often, it doesn't even solve any06:31
ailoFor some it's essential06:31
ailoI was thinking about the possibility of a gui control for it06:31
len-dtThats what modes is.06:31
len-dtTwo settings, one click to change.06:32
ailoHow does that change the rtirq?06:32
ailoAlso, maybe the script could be enhanced06:32
len-dtRun it against two configs of need be.06:32
ailoI have no problem with investigating modes. I'm all for it. But, I don't think it's the place to start off. Rather the place to end up in as a last resort06:34
len-dtI'm 50/50 on that... one of my machines needs it for sure the other has less uses and so doesn't.06:35
len-dtA desktop machine with one use in mind, just needs permanent tweaks.06:36
ailoI'd rather see about fixing everything that can be fixed statically first06:36
ailoDamn, it's not even hot here, and I'm sweating06:37
len-dtthis is our first warm weekend... we are all to hot.06:38
len-dta laptop that gets used for everything from games and browsing to maybe some accounting with sql running and oh by the way we want to be able to record or run the guitar through it too, needs an off switch for all the junk06:41
len-dtEven while accounting with sql turned on, it might be nice to turn everything else off.06:42
len-dt(SQL eats memory worse than almost anything)06:43
ailoI guess it's kind of a nice feature to be able to get good performance, even when the system is totally messed up :). But it's also a bit up to the user. Even if the initial install is super, it is possible to mess it up06:44
len-dtIt is not messed up just because the user wants to use the system more than one way.06:45
ailoI haven't looked more closely into the mods thing, but from what I've gathered, there are things that get turned off that you might not want to06:45
len-dtThe main user of US will want just an audio machine or just video06:45
len-dtThey will want to set and forget.06:46
ailoI don't think used modes is a good "general" approach anyway06:46
ailosuing*06:46
len-dtuh oh it s legal action now ;-)06:47
ailohehe06:47
ailousing*06:47
ailoBut let's say there is a mode that gets automatically turned on with jack06:48
ailoAnd you can tweak what the mode will do06:48
ailoThe initial mode should be more or less what a normal install would be06:49
ailoIn a preference window you could choose to toggle things off06:49
len-dtYa.06:50
len-dtThats the idea.06:50
ailoI could live with that. Especially if I didn't need to bother even knowing it happened, as long as I didn't need to06:50
ailoWe could add the mode preferences to -controls06:51
len-dtThat would be a good place.06:51
ailoAnd if a workflow bar is ever created, the -controls could live there06:51
ailolen-dt: A system like that might become the envy of the linux audio world ;)06:53
len-dtCould do that or even be a part of it... but two separate pieces would be more flexable.06:53
ailoI'm going to try keep -controls in modules as much as possible06:53
ailoThere's a menu in the indicator bar, but the menu items are each separate programs06:54
len-dtNo need for envy... anyone can have it ;-)   (I get the drift)06:54
ailoSo, a mode preference item would also be a separate program06:55
ailoThe menu would mostly just open them06:55
ailoAlso, the icon in the menu might change color if there is something wrong06:55
len-dtI would like the naming to be generic so it could get used even outside audio.06:55
ailoI did a startup script last year for checking if the system was well tweaked for audio. If it wasn't, a popup after booting would let you know you should configure using -controls06:56
len-dtThe mode program I have been using is a tray item, The icon in the tray shows what the mode is. When clicked on there is a drop down menu to choose the new mode.06:56
ailoOk06:56
ailoI think I'd rather have the mode enabled with jack, and that in preferences, you can make it not run06:57
len-dtone of the dropdown menu items should/will be the config part. (call it controls or whatever.06:57
ailoI think a config window should be enough06:58
len-dtThe actual mode change is done with a CLI command. so it would be possible to have Jack prerun it.06:58
len-dt and post stop it.06:58
* len-dt does simple stuff... as few lines as he can.06:59
ailosimple is best :)06:59
len-dtanyway, it is late for me, midnight, I should go to keep wife warm...07:00
len-dtGN07:00
ailoGN len-dt 07:00
holsteinailo: yup... the idea of ven upgrading my production rig to 12.04 is daunting14:30
holstein"if it aint broke", ya know?14:30
holsteini think we are just mostly audio guys here, which is not bad necessarily14:31
holsteini look forward to cultivating some more video heavy users14:32
len-dtIts good for me I am learning lots ;-)14:32
holsteini know Scott was doing some video14:32
len-dtvideo takes a whole different artistic bent.14:33
holsteinits such a commitment... new software and workflow14:33
holsteini cant casually keep up with it to provide better support14:34
holsteinwell... i could, but im not going to take the tie it would take14:34
len-dtThe videos I have seen from Scott so far, show good use of of tools, but the content is less than stellar. Good how to stuff.14:34
holsteinyup... he's doing great at learning the ropes and showing what can be done14:34
len-dtIt is like me with keyboards, I can make a few chords and understand the midi specs and what it does... but I am no keyboard player14:36
holsteinyou N.A.R.K. !14:36
holsteinim a nark and a narg14:37
holsteinnot a real keyboardist/guitarist :)14:37
len-dt:-)14:37
holsteini can do OK at fielding some midi questions14:38
len-dtI could say the same... it is easy to see what I can't do.14:38
holsteini can help folks find things too.. but with video, i got no clue14:38
len-dtYa, if the program description says video it might work...14:39
holsteinthat too... and you might not be able to use one program for everything14:39
len-dtIf it says "player" probably not.14:39
len-dtI do have a pretty good idea how a video workflow goes, I used to work in TV, but it was all analog.14:41
len-dtearly 80s14:41
holsteinyeah, its all different14:41
holsteini feel like if you know a professional workflow for audio, JACK really makes sense14:41
len-dtJust not all real time-ish14:41
holsteinsome of the other stuff we have too... im not sure that is true for video14:41
len-dtThe one thing I find missing from video equipment is timecode14:43
len-dtThe video to sound has to be synced by eye.14:43
len-dtWe used to run TC cables to everything.14:44
len-dtOne master clock14:44
holsteingtg... bbl! :)14:45
ailo_len-dt: No work on that? midi? jack? lv2?14:45
len-dtIt has to do with the camera hardware14:46
len-dtI think the video file format can handle it ok.14:46
len-dtBut the TC has to be added at the camera for it to be any use.14:47
len-dtAnd as with audio, any two cameras will drift with time from each other.14:48
len-dtFor short videos it doesn't matter as we are not as sensitive to video/audio match up as we are to stereo match up for example.14:50
ailo_Recording sync is one thing14:51
ailo_Mixing another14:52
ailo_Both need to have sync14:52
len-dtIn audio SW we keep very close tabs on latency so we can keep sync, I don't know that video SW pays as much attention.14:53
len-dtMaybe it doesn't need to. A video that just has one shot from start to finish (goes around the world?) would be boring.14:55
ailo_The timecode needs to be relevant14:57
ailo_Otherwise, how will you know where to cut in audio?14:57
len-dtThe workflow might change depending on the material for video. A live event starts with the audio and puts video on top, a movie starts with video and does audio after.14:57
len-dtin the video world the timecode is based on real time.14:58
len-dtReal time as in wall clock14:58
len-dtailo_, in the blue prints there is mention of removing thunar or at least replacing it for the desktop.16:36
len-dtThe list of things that depend on it is quite long.16:36
