HedgeMagejsgotangco: I just suggested to highvoltage that it might be nice to make a spot on the web site for the newsletters so they are a bit more promenant.  I've had a few people ask about it, and I had to dig it up from list archives.08:23
HedgeMagejsgotangco: I was also wondering if I could write a small spot on Cookbook progress for future ones.08:24
highvoltageHedgeMage: that's a good idea08:24
highvoltageHedgeMage: i'll get that in08:24
HedgeMagehighvoltage: thanks :)08:25

Burgundaviait is standalone, that is the brilliant part08:41
HedgeMageooh08:42
HedgeMageinteresting08:42
Burgundaviaall it uses is the same backend, but that means it also integrate into your panel just like evo08:42
Burgundaviait is the direction evo should be taking08:42
HedgeMageI used to use a paper planner, I really like that better, but, well, I have a toddler :P08:42

DanielCUse edubuntu05:15
PetarisDanielC: And then just apt-get xubuntu?05:16
DanielCI'd guess:  xubuntu-desktop05:16
DanielCNote: I haven't tried this myself.05:16
Petarisok05:16
PetarisI'll give that a try05:17
DanielCLet me know if it works, I'd be interested to know.05:17
Petariswell, thats how I did it last time05:18
Petarisbut I was curious if I could avoid getting all the gnome and kde stuff05:19
DanielCYes you can, but it's probably more difficult.05:19
DanielCInstalling xubuntu-desktop afterwards is easier than configuring ltsp afterwards.05:20
Petarisok05:20
DanielCBut you can try it that way. You *will* get it to work eventually. I've never done it, but it can certainly be done.05:20
Petarishrm05:21
PetarisI might play with doing it that way then05:21
Petarisjsut for the hell of it05:21
DanielCIt would be a learning experience.05:21
DanielCIf I get a chance I think I'll try that too on a test server.05:21
Petarisyep, if its not difficult I could write a how-to05:22
PetarisDanielC: Dapper or Edgy?05:22
DanielCDapper05:23
Petarisok05:23
YagisanPetaris: it is easier to install edubuntu first, but no, you don't need edubuntu installed to set up ltsp05:27
YagisanPetaris: you can install xubuntu, then install ltsp, you'll just need to manually configure ltsp05:28
PetarisYagisan: ok, I'm going to try using xubuntu as the base just to try it05:28
PetarisYagisan: Is it the latest ltsp?05:28
YagisanPetaris: I used normal ubuntu as the base for myself05:28
DanielCWhat's the advantage of using Xubuntu other than personal preference?05:28
PetarisI heard there is a new version out05:28
YagisanPetaris: in dapper ? yes05:28
YagisanPetaris: ltsp.org and ubuntu ltsp work differently05:29
PetarisDanielC: less overhead for terminals05:29
YagisanPetaris: ubuntu's ltsp is the next generation version05:29
DanielCGnome really adds overhead on the terminals?05:29
PetarisYagisan: oh damn, thats right05:29
PetarisDanielC: compared to xfce4 it does05:29
YagisanPetaris: sudo aptitude install ltsp and it's installed. Then you need to configure it05:29
DanielCok05:30
PetarisYagisan: right05:30
PetarisDanielC: When you are running a number of clients the overhead adds up05:30
Petarisits not like just running a single instance05:30
DanielCIt isn't?05:32
DanielCIsn't that the whole point of using thin clients?05:32
DanielCThat you don't have to duplicate the heap for every user?05:32
Petarisyou get an instance for each client05:33
Petaristhe point is low cost hardware and easy upgrade/managability05:33
DanielCBut running two instances of Gnome on the same computer still shares the same heap.05:33
DanielCIt's just the user data that changes.05:33
DanielC(and hence, can't be shared)05:33
DanielCThe reason why the hardware is low cost is that you're not duplicating everything for every user.05:34
Petarislow cost hardware because no disk drives, and the bulk of the processing is done server side05:39
DanielCThe reason why the server doesn't require the resources of 20 computers to run 20 clients is that you are not replicating everything.05:40
DanielCIf a regular computer requires 512MB of RAM, running LTSP with 10 terminals does not require 5120MB of RAM.05:40
DanielCIn fact, 1-2GB will do.05:41
DanielCBecause 90% of what's in RAM is the heap (the code itself for the application) and that stuff is not replicated.05:41
DanielCIt's the same reason why having two Firefox windows open doesn't take up twice as much RAM as having one.05:41
PetarisMy perception in running is that xfce is faster and lighter then gnome05:43
DanielCI'm not arguing with that :)05:43
Petarisand thus was a better choice for a thin-client enviornment05:43
DanielCI didn't say Gnome was as fast as xfce. I said that you're not duplicating all of gnome for each user.05:43
Petarisperhaps not05:44
DanielCWhether it's better depends on what you are trying to accomplish.05:44
Petarisfor me xfce does what I need05:44
PetarisI would love to know why OO.org eats so many more resources on edubuntu then on k12ltsp05:46
PetarisI wonder what the difference is05:46
Petariswas OO.org modified on one of these distros?05:47
DanielCNo idea.05:47

Petarishow can I start an xfce session over ssh?08:55
Petarisdo I just issue a startx?08:57
PetarisI wouldn't think so08:57
Petaris*as X is already running on that system08:57
dan_youngPetaris: can you ssh -X to the server, then Xnest -query localhost :109:01
Petarishrm, I don't have Xnest09:02
Petarishrm09:03
Petarisis it safe to apt-get it?09:03
Petaristhat is, will it scew up Xorg?09:03
Petarisor try to remove it or something09:03
dan_youngPetaris: shouldn't be a problem, not sure what package it is in, just a sec....09:04
dan_youngXnest goes on the system you're ssh'ing to, of course...09:04
Petarisright09:05
Petarisbut its an ltsp server and I don't want to screw anything up09:05
dan_youngsure, package name is xnest, it is just an "Xserver in a window"09:06
Petarisok, cool09:06
dan_youngPetaris: hmm, needs XDMCP on to do "remote" login, even though we're coming from localhost...09:08
