Eeyore-Jr_Nubae: i'm going to start on my fat client.  what link did you give me this morning?02:01
Eeyore-Jr_on a fat client, is there a way to get it to only run the graphics programs ?  my fat client would run programs slower than the server.02:02
Ahmuckis edubuntu a "add-on" cd now ?02:48
stgraberyes, since 8.0402:50
LaserJockhi stgraber03:00
stgraberhey LaserJock03:02
LaserJockstgraber: nice work on LTSP lately03:03
stgraberyeah, working full-time on it helps :)03:03
LaserJockstgraber: Intrepid might work out afterall ;-)03:03
stgraberI'm finishing the localapps implementation for ltsp-cluster now (testing it basically), then will propose the change upstream03:04
stgraberbasically it's about generating a "Local applications" menu with the softwares that are installed in the chroot03:04
stgraberso you can do fullscreen youtube with firefox, blender, audacity or skype video conf which weren't possible before03:04
Eeyore-Jrwithout a "fat" client?03:04
stgraberyeah03:05
Eeyore-Jrneat03:05
Eeyore-Jrreally neat03:05
Eeyore-Jrhow does that work?03:05
Eeyore-Jrtheoretically03:05
stgrabersoftwares are installed in the chroot, an entry is added to /etc/ltsp/localapps-menu/ with a .desktop for that softwares03:06
stgraberwhen the user session open, a rc.d script is run that'll generate a xdg menu off it03:06
stgraberso the menu entries will appear on the server, clicking on it will set a X property that's read on the thin client and will trigger the software you clicked03:06
LaserJockI'd love to be able to run chemistry apps locally03:08
Eeyore-Jrah, they run locally?03:08
LaserJockthat's been a big sticking point to me pushing to do an LTSP deployment in my department03:08
Eeyore-Jrso to run large graphics you would still need a machine capable of doing it03:09
Eeyore-Jron the client side?03:09
LaserJockyeah03:09
Eeyore-Jrhrm03:09
Eeyore-Jrso, how do you mix thin and fat then, still have to tell it by mac address?03:09
LaserJockthe point of localapps is to shift CPU load to the client03:09
stgraberLaserJock: yeah, we were requested to make blender, celestia and some other edu software to work on thin clients, local apps help a lot for that :)03:10
LaserJockEeyore-Jr: you have the local apps you want installed in the chroot03:10
LaserJockEeyore-Jr: it's still a thin client03:10
stgraberEeyore-Jr: localapps can be turned on/off using the LOCALAPPS lts.conf parameter, so you can turn it off for computers that can't run it03:10
Eeyore-Jri'm confused sorta03:10
Eeyore-Jrhow does the server know when to turn them off?  mac address?03:11
Eeyore-Jrlisting ?03:11
stgraberthe menu being generated by the thin client, the server doesn't need to know about it03:11
Eeyore-Jrcan i keep asking questions without being annoying.  i'm still trying to understand what's going on03:12
Eeyore-Jrthe menu that is generated by the thin client is generated according to it's specs?03:12
Eeyore-Jrit generates a "thin" menu if it has certian hardware specs?03:13
LaserJockstgraber: I guess what Eeyore-Jr is asking is what happens if you have mixed thin clients, only some of which you want to run localapps on03:13
LaserJockstgraber: can you set LOCLAPPS on a per/client basis?03:13
Eeyore-Jri was under the impression that "fat" clients were beefier machines, and requried a special mac addressing schema on the server to identify them03:14
stgraberLaserJock: yes03:14
LaserJockEeyore-Jr: I think ^^ answers your question03:14
Eeyore-Jrok, let me re-phrase.  i have 450mhz, 256mb ram machines, but would like to run some gl games, which would require machines with higher specs, such as 1Ghz, 512MB, and 64MB video memory03:15
stgraberyou can turn on/off the localapps using lts.conf which uses mac address, so you can turn off localapps for some thin clients03:15
Eeyore-Jron a file on the server03:15
Eeyore-Jror a file with a mac address list so that heavy apps are not turned on03:15
stgraberI'm working on ltsp-cluster where we have a control center that's used to generate lts.conf based on some attributes (including hardware specifications) but it's probably a bit too big for your own installation03:15
stgraber(we use it with load balancing for really big networks)03:16
LaserJockEeyore-Jr: lts.conf is on the server03:16
Eeyore-Jractually, i've been thinking about a bewolf ltsp cluster.  is that possible?03:16
Eeyore-Jrparallel ltsp ?03:16
Eeyore-Jrwell, i think i have a better idea what's going on.  thx for the info, i'll put it in my planning03:18
Eeyore-Jrit's late.  gnite03:18
Eeyore-Jr_one thing i noticed is that there were full menus for ltsp.  menus for installing software, etc.  i assume menus can be customized.  installing software always brought up a password prompt.  i can see users confusion on this04:10
LaserJockEeyore-Jr: why?04:10
sbalneavEvening all04:10
LaserJocksbalneav!04:11
sbalneavHey LaserJock04:11
stgraberhey sbalneav04:11
stgrabersbalneav: I implemented a "Local applications" menu today, generated by the thin client from a config file in /etc/ltsp/localapps-menu/ :)04:12
sbalneavNice04:13
LaserJockwe should set a time for a Jaunty planning meeting04:23
stgraberyep04:23
LaserJockWed. 20:00 UTC?04:27
stgraberhmm, with release on Thursday, I'd prefer after-release04:28
stgraberand 19:00 UTC would be better as I need to leave the office at 21:00 UTC (and last hour is usually quite busy)04:29
stgraberFriday 19:00 UTC would be great (or any time starting from 12:00 UTC)04:30
sbalneavSigh04:34
sbalneavMultibin printing doesn't work in OpenOffice.org in Intrepid.04:34
LaserJockI can't do it earlier than 19:00 UTC on Friday04:35
LaserJockbut 19:00 would work04:35
LaserJocksbalneav: no?04:36
sbalneavNo.04:37
sbalneavI'll have to dig into it.04:37
LaserJocksbalneav: can you tell if it's on the OO.o end?04:37
stgraberLaserJock: ok, so let's go with Friday 19:00 UTC04:37
sbalneavUbuntu will never, EVER, make it big in business if it can't get this right.04:38
sbalneavNo idea.  It didn't work for hardy, either.04:38
sbalneavI came up with a patch for cups upstream.04:38
sbalneavthe pstops filter was broken hard.04:39
sbalneavTalked to Till in #ubuntu-devel, pointed him to the fix, but it's never been patched.04:39
sbalneavNow cups has changed YET AGAIN, with the "all pdf all the time" printing method.04:40
sbalneavso now, it's broken.04:40
sbalneavagain.04:40
sbalneavAnd I'll have to fix it.04:40
sbalneavAgain.04:40
stgraberArgh, looks like I found a way to break ltsp-cluster so my test terminal doesn't boot ... of course it's 30km away and my only way to access it until Monday is ssh ...04:41
stgraberI wish I'd have my test lab at home, would be a lot easier04:41
LaserJockstgraber: what about the next Wednesday?04:49
LaserJockI just realized that Friday would be Halloween here04:50
LaserJockand I'm not sure what my schedule will be since I have the day off04:50
LaserJocksbalneav: what does multibin printing do btw?04:51
stgraberoh right, forgot about halloween.04:51
stgraberLaserJock: Wednesday early afternoon is fine, then I'll need to pack stuff for LTSP BTS04:52
LaserJockso Nov. 5th at 20:00UTC04:52
LaserJockthat'd be one of our usual Edubuntu meeting times anyway04:52
stgraberhmm, that's not really early afternoon in my tiemzone :)04:52
sbalneavWell, with a laser printer in an office environment, you'll often have at least 3 bins:04:52
stgraber17:00UTC or 18:00UTC would be a lot better04:53
sbalneav1 for plain, one for letterhead, and an envelope feeder.04:53
sbalneavAnd often, the manual feed tray filled with legal size.04:53
LaserJockoh04:53
LaserJockI thought it was an LTSP thing :-)04:53
sbalneavCurrently, no matter what you set the paper tray as, it comes out on the default bin.04:54
sbalneavWhich means it's a complete non-starter to move to.04:54
LaserJockstgraber: Ubuntu QA meeting is 17:00-18:00, should we go for 18:00?04:54
stgraberah right, the QA meeting :) yeah let's go with 18:0004:55
stgraberI know of some people at Revolution Linux who will likely also be interested in attending the meeting04:57
stgraberwhere do we do it ? #ubuntu-meeting04:57
LaserJockyeah04:58
LaserJockI'm writing up an email to edubuntu-devel04:58
LaserJockstgraber: anywhere else you think I should send it?04:59
LaserJockheck, maybe I should CC ubuntu-devel04:59
stgraberyeah, ubuntu-devel may be good too04:59
stgrabermaybe edubuntu-users ? I'm not sure who we have on that list though (I'm not subscribed)04:59
stgrabersend it to the fridge mailinglist too so it gets added to the fridge05:00
stgraberubuntu-news-team@l.u.c that's05:01
highvoltagestgraber: thanks :)06:51
